Background Understanding predictors for the recovery of erectile function (EF) after nerve-sparing radical prostatectomy (nsRP) might help clinicians and patients in preoperative counseling and expectation management of EF rehabilitation strategies. Objective To describe the effect of potential predictors on EF recovery after nsRP by post hoc decision-tree modeling of data from A Study of Tadalafil After Radical Prostatectomy (REACTT). Design, setting, and participants Randomized double-blind double-dummy placebo-controlled trial in 423 men aged <68 yr with adenocarcinoma of the prostate (Gleason ≤7, normal preoperative EF) who underwent nsRP at 50 centers from nine European countries and Canada. Intervention Postsurgery 1:1:1 randomization to 9-mo double-blind treatment with tadalafil 5 mg once a day (OaD), tadalafil 20 mg on demand, or placebo, followed by a 6-wk drug-free-washout, and a 3-mo open-label tadalafil OaD treatment. Outcome measurements and statistical analysis Three decision-tree models, using the International Index of Erectile Function-Erectile Function (IIEF-EF) domain score at the end of double-blind treatment, washout, and open-label treatment as response variable. Each model evaluated the association between potential predictors: presurgery IIEF domain and IIEF single-item scores, surgical approach, nerve-sparing score (NSS), and postsurgery randomized treatment group. Results and limitations The first decision-tree model (n = 422, intention-to-treat population) identified high presurgery sexual desire (IIEF item 12: ≥3.5 and <3.5) as the key predictor for IIEF-EF at the end of double-blind treatment (mean IIEF-EF: 14.9 and 11.1), followed by high confidence to get and maintain an erection (IIEF item 15: ≥3.5 and <3.5; IIEF-EF: 15.4 and 7.1). For patients meeting these criteria, additional non-IIEF–related predictors included robot-assisted laparoscopic surgery (yes or no; IIEF-EF: 19.3 and 12.6), quality of nerve sparing (NSS: <2.5 and

To examine the feasibility of using laser energy during nerve-sparing robotically assisted radical prostatectomy (RARP), as the energy sources currently used for haemostasis in RARP adversely affect cavernous nerve function, while clips require application by a skilled assistant, but laser energy potentially allows precise dissection with minimal collateral tissue injury. We used laser-based RARP in 10 dogs, using the da Vinci S system (Intuitive Surgical, Sunnyvale, CA, USA) and a prototype robotic laser instrument. The potassium-titanyl-phosphate laser was used for dissection at 2-6 W, with intermittent use of the neodymium-doped yttrium-aluminium-garnet laser at 5 W for coagulating larger vessels. The peak intracavernosal pressure response to nerve stimulation was recorded as a percentage of mean arterial pressure (ICP%MAP) before and after RARP. Five dogs were killed immediately after RARP and five were maintained alive for 72 h; the haemoglobin and haematocrit levels were measured before and after RARP in the latter five dogs. All 10 procedures were performed solely using laser energy and no additional haemostatic manoeuvres. The median prostate excision time was 65 min. The ICP%MAP before and after RARP (median 98.5% and 77.0%, P = 0.12) were not significantly different; similarly, the respective haemoglobin (median 14.4 vs 12.6 g/dL, P = 0.06) and haematocrit levels (45.1% vs 40.2%, P = 0.06) were not significantly different. Two dogs had catheter-related complications and one had an anastomotic leak. There were no laser-related complications or postoperative haemorrhage. Laser RARP is feasible in dogs and further assessment is warranted.

Introduction: While the effects of increasing body mass index on prostate cancer epidemiology and surgical approach have recently been studied, its effects on surgical outcomes are less clear. We studied the perioperative outcomes of obese (BMI >= 30) men treated with daVinci-assisted laparoscopic radical prostatectomy (DLP) and compared them to those treated with open radical retropubic prostatectomy (RRP) in a contemporary time frame. Method: After Institutional Review Board approval, we used the Mayo Clinic Radical Prostatectomy database to identify patients who had undergone DLP by a single surgeon and those who had undergone open RRP by a single surgeon between December 2002 and March 2005. Baseline demographics, peri- and post-operative courses, and complications were collected by retrospective chart review, and variables from the two cohorts compared using chi-square method and least-squares method of linear regression where appropriate. Results: 59 patients who had DLP and 76 undergoing RRP were available for study. Baseline demographics were not statistically different between the two cohorts. Although DLP had a significantly lower clinical stage than RRP (p=0.02), pathological stage was not statistically different (p=0.10). Transfusion rates, hospital stay, overall complications, and pathological Gleason were also not significantly different, nor were PSA progression, positive margin rate, or continence at 1 year. After bilateral nerve-sparing, erections suitable for intercourse with or without therapy at 1 year was 88.5% (23/26) for DLP and 61.2% (30/49) for RRP (p=0.01). Follow-up time was similar. Conclusion: For obese patients, DLP appears to have similar perioperative, as well as short-term oncologic and functional outcomes when compared to open RRP.

To evaluate sexuality and erectile function of candidates for radical prostatectomy in order to assess the place of nerve-sparing surgery in the preoperative discussion. From June 2004 to January 2005, 75 consecutive patients, candidates for radical prostatectomy, were prospectively evaluated. Their erectile function and sexuality were evaluated after announcing the diagnosis. Patients completed the IIEF (International Index of Erectile Function), EQS (Erection Quality Scale) and the sexual satisfaction score (SSS). The mean age of the patients was 65 years and 50% were younger than 65. Erectile dysfunction according to the IIEF-5 scale was observed in 64% of cases (43% of patients younger than 65 and 84% of patients over 65). Erectile dysfunction was considered to be severe in 5% of young patients versus 34% of patients over 65. The majority of patients (69%) had a sexual activity more than twice a month. Only 31% of patients under 65 and 8% of older patients considered their erections to be very satisfactory according to the EQS. Despite this high frequency of erectile dysfunction in men over the age of 65, sexual satisfaction was not influenced by erectile dysfunction. In contrast, patients younger than 65, erectile dysfunction clearly altered the SST sexual satisfaction score. Erectile dysfunction was present in a large proportion of candidates for radical prostatectomy. The presence of erectile dysfunction in patients over the age of 65 did not modify their sexual satisfaction score. A detailed clinical interview concerning sexuality should be conducted to select patients likely to benefit from nerve-sparing surgery. Nerve-sparing surgery would be beneficial in young patients in whom sexual satisfaction is dependent on erectile function. In the older men, erectile dysfunction can be present without affecting sexual satisfaction.

To systematically assess the efficacy and safety of oral sildenafil citrate for post bilateral nerve-sparig radical prostatectomy (post-BNSRP) erectile dysfunction (ED). The following keywords: sildenafil, radical prostatectomy were used to search in Medline, Pubmed, Web of Science, Cochrane Library, CNKI, WanFang Database. The title, abstract and keywords of each article were independently screened by two reviewers. Randomized controlled trials (RCT) published between 1990 and 2014 were retrieved according to our inclusion and exclusion criteria. The efficacy and safety of oral sildenafil citrate for post-BNSRP ED were systematically assessed by meta-analysis. Four RCTs with 320 cases were included after literature retrieval and filtering. The potency rates were 32.1% (35/109) and 11.3% (7/62) between sildenafil and placebo groups after meta-analysis and showed statistically significant differences (OR = 4.66, 95% CI: 1.79-12.11). IIEF-5 score in sildenafil group was significant higher than that in the placebo group (WMD: 4.73, 95% CI: 3.26-6.19). In subgroup meta-analysis, the potency rates in high-dose, low-dose sildenafil groups and placebo groups were 30.4% (14/46), 25.0% (10/40) and 4.5% (2/44), respectively. There were statistically significant differences between the high-dose subgroup and placebo group (OR = 9.32, 95% CI: 1.96-44.23), and the low-dose subgroup and placebo group (OR = 6.99, 95% CI: 1.43-34.22). But there was no significant difference between high-dose and low-dose subgroups (OR = 1.31, 95% CI: 0.51-3.40). Compared with placebo, sildenafil has considerable efficacy for erectile function rehabilitationas as a primary treatment for post-BNSRP ED. There is no significant difference between high-dose and low-dose schedule for its efficacy. However, further studies are required to optimize treatment.

Abstract Background and Purpose Various imaging modalities are under investigation for real-time tissue imaging of periprostatic nerves with the idea of improving the results of nerve-sparing radical prostatectomy. We explored multiphoton microscopy (MPM) for real-time tissue imaging of the prostate and periprostatic neural tissue in a male Sprague-Dawley rat model. The unique advantage of this technique is the acquisition of high-resolution images without necessitating any extrinsic labeling agent and with minimal phototoxic effect on tissue. Materials and Methods The prostate and cavernous nerves were surgically excised from male Sprague-Dawley rats. The imaging was carried out using intrinsic fluorescence and scattering properties of the tissues without any exogenous dye or contrast agent. A custom-built MPM, consisting of an Olympus BX61WI upright frame and a modified MRC 1024 scanhead, was used. A femtosecond pulsed titanium/sapphire laser at 780-nm wavelength was used to excite the tissue; laser power under the objective was modulated via a Pockels cell. Second harmonic generation (SHG) signals were collected at 390 (±35 nm), and broadband autofluorescence was collected at 380 to 530 nm. The images obtained from SHG and from tissue fluorescence were then merged and color coded during postprocessing for better appreciation of details. The corresponding tissues were subjected to hematoxylin and eosin staining for histologic confirmation of the structures. Results High-resolution images of the prostate capsule, underlying acini, and individual cells outlining the glands were obtained at varying magnifications. MPM images of adipose tissue and the neural tissues were also obtained. Histologic confirmation and correlation of the prostate gland, fat, cavernous nerve, and major pelvic ganglion validated the findings of MPM. Conclusion Real-time imaging and microscopic resolution of prostate and periprostatic neural tissue using MPM is feasible without the need

Nerve-sparing techniques to avoid bladder dysfunction in abdominal radical hysterectomy have been established during the past two decades, and they have been applied to radical trachelectomy. Although trachelectomy retains the uterine corpus, no report mentions the preservation of uterine branches of pelvic nerves. The aim of the present study was to introduce and discuss our unique concept for preserving them. Four cases with FIGO stage Ia2-Ib1 cervical cancer, in which preservation of uterine branches of the pelvic nerves was attempted, are presented. Operative procedures basically followed the previously reported standard approaches for nerve-sparing radical hysterectomy or trachelectomy, except for some points. Before resection of the sacrouterine ligament, the hypogastric nerve was first identified and translocated laterally. Subsequently, the uterine branches of the pelvic nerve were identified as a continuation of the hypogastric nerve and could be scooped with forceps by detachment of the surrounding connective tissues. Further detachment toward the uterine corpus enabled them to be completely separated from the cervix. This separation was extended up to the level of the junction of the upper and lower branches of the uterine artery. Thereafter, standard resection of the parametrium and paracolpium was performed, followed by cervical resection when it was confirmed that the isolated uterine branches of the pelvic nerves were safely translocated and preserved. There were no recurrences of cancer in these patients. Uterine branches of autonomic nerves can be safely preserved, and the procedure may be considered one of the nerve-sparing techniques for radical abdominal trachelectomy, which may hopefully improve the reproductive outcomes of this operation, although it needs to be evaluated with more patients.

Abstract Robot-assisted radical prostatectomy (RARP) has enabled steady and stable surgical procedures due to both meticulous maneuvers and magnified, clear, 3-dimensional vision. Therefore, better surgical outcomes have been expected with RARP than with other surgical modalities. However, even in the RARP era, post-prostatectomy incontinence has a relatively high incidence as a bothersome complication. To overcome post-prostatectomy incontinence, it goes without saying that meticulous surgical procedures and creative surgical procedures, i.e., “Preservation”, “Reconstruction”, and “Reinforcement” of the anatomical structures of the pelvis, are most important. In addition, medication and appropriate pad usage might sometimes be helpful for patients with post-prostatectomy incontinence. However, patients who have 1) BMI > 26 kg/m2, 2) prostate volume > 70 mL, 3) eGFR < 60 mL/min, or a 4) Charlson comorbidity index > 2 have a tendency to develop post-prostatectomy incontinence despite undergoing the same surgical procedures. It is important for patients who have a high risk for post-prostatectomy incontinence to be given information about delayed recovery of post-prostatectomy incontinence. Thus, not only the surgical procedures, but also a comprehensive approach, as mentioned above, are important for post-prostatectomy incontinence. PMID:28747618

Good clinical care of prostate cancer patients after radical prostatectomy depends on careful assessment of post-operative morbidities, yet physicians do not always judge patient symptoms accurately. Logistical problems associated with using paper questionnaire limit their use in the clinic. We have implemented a web-interface ("STAR") for patient-reported outcomes after radical prostatectomy. We analyzed data on the first 9 months of clinical implementation to evaluate the validity of the STAR questionnaire to assess functional outcomes following radical prostatectomy. We assessed response rate, internal consistency within domains, and the association between survey responses and known predictors of sexual and urinary function, including age, time from surgery, nerve sparing status and co-morbidities. Of 1581 men sent an invitation to complete the instrument online, 1235 responded for a response rate of 78%. Cronbach's alpha was 0.84, 0.86 and 0.97 for bowel, urinary and sexual function respectively. All known predictors of sexual and urinary function were significantly associated with survey responses in the hypothesized direction. We have found that web-based assessment of functional recovery after radical prostatectomy is practical and feasible. The instrument demonstrated excellent psychometric properties, suggested that validity is maintained when questions are transferred from paper to electronic format and when patients give responses that they know will be seen by their doctor and added to their clinic record. As such, our system allows ready implementation of patient-reported outcomes into routine clinical practice.

The present study aimed to systematically evaluate the effectiveness and safety of the intrafascial and interfascial nerve sparing (ITR-NS and ITE-NS) radical prostatectomy. PubMed, Embase, and Cochrane Library databases were searched for eligible studies. Meta-analysis with random-effects model was performed. Six comparative trials were selected and embraced in this research, including one randomized controlled trial, three prospective comparative trials, and two retrospective comparative trials. With regard to perioperative parameters, no significant association of operative time, blood loss, transfusion rates, duration of catheterization, and hospital stay existed between ITR-NS and ITE-NS. With respect to the functional results, ITR-NS had advantages in terms of both continence and potency recovery compared with ITE-NS. In reference to the oncologic results, the ITR-NS showed lower overall positive surgical margin (PSM) compared with ITE-NS but pT2 PSM and biochemical recurrence free rates were similar to the two surgical types. This study demonstrates that ITR-NS has better continence at 6 mo and 36 mo and better potency recovery at 6 mo and 12 mo postoperatively, regardless of the surgical technique. The cancer control of ITR-NS was also better than that of ITE-NS. This may be explained by the fact that patients in ITE-NS group present higher risk cancer than patients in ITR-NS group.

The main objective of radical prostatectomy (RP) is optimal oncologic resection with preservation of sexual function (SF). During our initial experience with robot-assisted laparoscopic radical prostatectomy (RLRP), we noted a high rate of posterolateral location of positive surgical margins (PSM) with nerve preservation (NP). With its magnified view of the surgical field and improved instrument precision, one potential advantage of RLRP is the ability to tailor the degree of NP. We evaluated the effect of a protocol for side-specific NP based on preoperative variables on PSM rates and SF outcomes. Between June and November 2006, 150 consecutive RLRPs were performed using a surgical protocol to select side-specific NP techniques (interfascial [IF], partial extrafascial [pEF], and wide extrafascial resection [WEFR]) based on preoperative risk factors (clinical stage, biopsy Gleason score, percentage of positive cores and maximal core cancer percentage, and preoperative PSA). Pathologic and SF outcomes in these patients were compared with those of a control group of 245 consecutive RLRPs in whom non-selective IF dissection was performed. All data were prospectively collected. Mean patient age, PSA, clinical stage, biopsy Gleason score and positive core involvement, pathologic Gleason score, and stage were comparable among the two groups. The overall PSM rate (12.6% nu 20.4%; P = 0.04) and posterolateral location of PSMs (37% nu 70%; P = 0.04) were significantly lower in the study group. At 12 months, potency was reported in 80%, 67%, and 11% of men undergoing bilateral IFNP, partial extrafascial nerve preservation (pEFNP), and WEFR, respectively (P = 0.27). Planning side-specific NP during RLRP, according to selected preoperative variables, can significantly reduce overall and posterolateral PSM rates. Furthermore, partial nerve sparing (pEFNP) also appears to confer favorable early SF outcomes.

Surgical anatomy of the prostate in the era of radical robotic prostatectomy.

New insights in the anatomy of the prostate and the surrounding tissue evolve the technique of radical prostatectomy for the treatment of prostate cancer. Regarding the course of the erectile nerves along the prostate, recent studies confirmed the presence of parasympathetic pro-erectile nerve fibers at the anterolateral aspect of the prostate. Another study of intraoperative electrostimulation of those nerves confirmed an increase in intracavernosal pressure by stimulations between the 1 and 3 o'clock position. Therefore, it is very likely that these anterior nerve fibers have an effect on erectile function. Regarding the urethral sphincter in the male, a study showed no attachment of the external sphincter to the levator ani muscle, probably resulting in an absence of a levator ani support to the continence mechanism. The male urinary sphincter seems to be in isolation responsible for urinary continence. The nerve fibers at the anterolateral aspect of the prostate seem to participate in erectile function, which renders the concept of a high anterior release during nerve sparing beneficial. The isolated urinary sphincter mechanism results in the need to conserve as much urethral length as possible during radical prostatectomy to avoid urinary incontinence.

We evaluated urinary and sexual quality of life 1 year following robotic laparoscopic radical prostatectomy and identified preoperative variables predictive of a severe decrease from baseline. Using a prospective robotic laparoscopic radical prostatectomy database we identified patients with greater than 1 year of postoperative followup. The UCLA-PCI SF-36v2 questionnaire was used to evaluate urinary and sexual quality of life before and 1 year after surgery. Severe worsening of the postoperative score was defined as a greater than 1 SD decrease. Demographic and preoperative clinical variables were evaluated along with baseline scores on univariate and multivariate analysis. Between February 2003 and September 2007 a total of 1,225 robotic laparoscopic radical prostatectomies were performed at our center and 361 patients (52%) met inclusion criteria. On multivariate analysis baseline urinary function was the only predictor of significant worsening of urinary function (OR 1.04, p = 0.003). Baseline urinary bother was the only predictor of significant worsening of urinary bother (OR 1.05, p <0.0001). A significant decrease in sexual function was predicted by baseline sexual function (OR 1.03, p = 0.0001), baseline sexual bother (OR 1.03, p = 0.005) and nerve sparing technique (OR 0.31, p = 0.05). Predictors of a significant decrease in sexual bother were also baseline sexual function (OR 1.02, p = 0.0001), baseline sexual bother (OR 1.04, p = 0.0007) and nerve sparing technique (OR 0.38, p = 0.02). ORs indicated that higher baseline scores corresponded to a higher risk of postoperative score worsening. We found that overall better baseline sexual and urinary scores are associated with better postoperative outcomes. However, the risk of a significant decrease in urinary function, urinary bother, sexual function and sexual bother is higher in patients with better baseline scores. Nerve sparing positively affects sexual function and sexual bother.

During nerve-sparing robot-assisted laparoscopic prostatectomy, nerve injury caused by thermal energy is a concern. Using a porcine model, we studied thermal spread and queried whether vessels such as the prostatic pedicle may act as a heat sink, reducing the spread of thermal energy. Monopolar (MP) and bipolar (BP) cautery was applied laparoscopically on the anterior abdominal wall surface of six pigs with the da Vinci robot. Using fiberoptic thermometry (Luxtron Inc. Santa Clara, CA), temperatures were recorded with and without the interposed inferior epigastric vessels to evaluate the heat sink effect. Interposition of the inferior epigastric vessels definitively demonstrated a heat sink phenomenon: at 7 mm from the MP/BP energy source, temperatures rose 10.7 degrees C to 13.8 degrees C without interposed vessels versus only 1.9 degrees C to 2.5 degrees C when vessels were interposed (P < 0.001). The heat sink phenomenon suggests that the prostatic vascular pedicle should be protective of the neurovascular bundle during transection of the bladder neck during laparoscopic prostatectomy.

Abstract To evaluate the role of multiparametric magnetic resonance imaging (mpMRI) in predicting upgrading, upstaging, and extraprostatic extension in patients with low-risk prostate cancer (PCa). MpMRI may reduce positive surgical margins (PSM) and improve nerve-sparing during robotic-assisted radical prostatectomy (RARP) for localized prostate cancer PCa. This was a retrospective, monocentric, observational study. We retrieved the records of patients undergoing RARP from January 2012 to December 2013 at our Institution. Inclusion criteria were: PSA <10 ng/mL; clinical stage nerve-sparing RARP. During surgery, the specimen was sent for FSA of the posterolateral aspects. The surgeon, according to the localization scheme provided by the mpMRI, inked the region of the posterolateral aspect of the prostate that had to be submitted to FSA. We evaluated association between clinical features and PSM, upgrading, upstaging, and presence of unfavorable disease. Two hundred fifty-four patients who underwent nerve-sparing RARP were included. PSM rate was 29.13% and 15.75% at FSA and final pathology respectively. Interestingly, the use of FSA reduced PSM rate in pT3 disease (25.81%). Higher PIRADS scores demonstrated to be related to high probability of upgrading and upstaging. This significativity remains even when considering PIRADS 2–3 versus 4 versus 5 and PIRADS 2–3 versus 4–5. Also PSM at FSA were associated with higher probability of upgrading and upstaging. PIRADS score and FSA resulted to be strictly related to grading and staging, thus being able to predict upgrading and/or upstaging at

In this study we identified preoperative or intraoperative factors responsible for the early return of continence after robot-assisted radical prostatectomy using data from a high volume center. Data from 1,299 patients who underwent robot-assisted radical prostatectomy performed by a single surgeon from January 2008 to June 2010 were collected prospectively and analyzed retrospectively. Patients were categorized according to whether they regained continence (no pad and no urinary leakage) within 3 months and variables were then compared. A self-administered validated questionnaire (Expanded Prostate Cancer Index Composite) was used for assessment of continence status and time to recovery. Within 3 months after surgery 86.3% of patients (1,121/1,299) had recovered continence. Multivariable Cox regression analysis revealed that only age (p <0.001, hazard ratio 0.98, 95% CI 0.97-0.99) and performance of a nerve sparing procedure were independent predictors. After adjusting for age, the hazard ratio was 1.61 (95% CI 1.25-2.07, p <0.001) for partial nerve sparing and 1.44 (1.13-1.83, p = 0.003) for bilateral nerve sparing compared to the nonnerve sparing group. Median time (95% CI) to the recovery of continence was prolonged in the nonnerve sparing group compared to nerve sparing counterparts at 6 (5.12-6.88), 4 (3.60-4.40) and 5 weeks (4.70-5.30) in the nonnerve sparing, partial nerve sparing and bilateral nerve sparing groups, respectively, with log rank p <0.01. Findings from our analysis indicate that the likelihood of postoperative urinary control was significantly higher in younger patients and when a nerve sparing procedure was performed.

Preservation of urinary continence is a great challenge in Radical Prostatectomy. In order to improve functional results, Asimakopoulos et al. (2010) described a robot-assisted surgical technique with preservation of the pubovesical complex (PVC). We present a pure laparoscopic execution. A 61-year-old male patient with a diagnosis of prostate cancer, with PSA 6.54ng/ml, DRE: T1C and Gleason 6 (3+3) 1/12 fragments. All therapeutic possibilities were discussed, including active surveillance. The patient opted for surgical treatment. A transperitoneal technique was used. We started the dissection on the left side, in the limit between the detrusor and the base of the prostate. The left seminal vesicle was dissected and left neurovascular bundle released by a high anterior dissection. We repeated the same procedure on the right side. The urethra was then divided, prostatic apex was laterally drawn and PVC was released. The bladder neck was divided and an urethrovesical anastomosis was achieved. A pelvic drain was placed. The total operative time was 150 minutes. The estimated blood loss was 300mL. The drain was removed on the 1st postoperative day and the patient was discharged. The Foley catheter was removed after 7 days and the patient remained completely dry. Hystopathology revealed adenocarcinoma Gleason 6, negative margins. PSA after 30 days was <0.04ng/mL, and the patient reported partial penile erection. The Pubovesical Complex-Sparing Technique on Laparoscopic Radical Prostatectomy was feasible and safe. Further adequately designed studies are needed to confirm whether this technique enhances early functional outcomes. Copyright® by the International Brazilian Journal of Urology.

Radical prostatectomy is a commonly performed procedure for the treatment of localized prostate cancer. One of the long-term complications is erectile dysfunction. There is little consensus on the optimal management; however, it is agreed that treatment must be prompt to prevent fibrosis and increase oxygenation of penile tissue. It is vital that patient expectations are discussed, a realistic time frame of treatment provided, and treatment started as close to the prostatectomy as possible. Current treatment regimens rely on phosphodiesterase 5 inhibitors as a first-line therapy, with vacuum erection devices and intraurethral suppositories of alprostadil as possible treatment combination options. With nonresponders to these therapies, intracavernosal injections are resorted to. As a final measure, patients undergo the highly invasive penile prosthesis implantation. There is no uniform, objective treatment program for erectile dysfunction post-radical prostatectomy. Management plans are based on poorly conducted and often underpowered studies in combination with physician and patient preferences. They involve the aforementioned drugs and treatment methods in different sequences and doses. Prospective treatments include dietary supplements and gene therapy, which have shown promise with there proposed mechanisms of improving erectile function but are yet to be applied successfully in human patients.

While radical prostatectomy surgeon learning curves have characterized less blood loss, shorter operative times, and fewer positive margins, there is a dearth of studies characterizing learning curves for improving sexual function. Additionally, while learning curve studies often define volume thresholds for improvement, few of these studies demonstrate specific technical modifications that allow reproducibility of improved outcomes. Demonstrate and quantify the learning curve for improving sexual function outcomes based on technical refinements that reduce neurovascular bundle displacement during nerve-sparing robot-assisted radical prostatectomy (RARP). We performed a retrospective study of 400 consecutive RARPs, categorized into groups of 50, performed after elimination of continuous surgeon/assistant neurovascular bundle countertraction. Our approach to RARP has been described previously. A single-console robotic system was used for all cases. Expanded Prostate Cancer Index Composite sexual function was measured within 1 yr of RARP. Linear regression was performed to determine factors influencing the recovery of sexual function. Greater surgeon experience was associated with better 5-mo sexual function (p = 0.007) and a trend for better 12-mo sexual function (p = 0.061), with improvement plateauing after 250-300 cases. Additionally, younger patient age (both p<0.02) and better preoperative sexual function (<0.001) were associated with better 5- and 12-mo sexual function. Moreover, trainee robotic console time during nerve sparing was associated with worse 12-mo sexual function (p=0.021), while unilateral nerve sparing/non-nerve sparing was associated with worse 5-mo sexual function (p = 0.009). Limitations include the retrospective single-surgeon design. With greater surgeon experience, attenuating lateral displacement of the neurovascular bundle and resultant neurapraxia improve postoperative sexual function. However, to maximize outcomes, appropriate patient

We investigated the effect of the use of multiparametric prostate magnetic resonance imaging (mp-MRI) on the dissection plan of the neurovascular bundle and the oncological results of our patients who underwent robot-assisted radical prostatectomy. We prospectively evaluated 60 consecutive patients, including 30 patients who had (Group 1), and 30 patients who had not (Group 2) mp-MRI before robot-assisted radical prostatectomy. Based on the findings of mp-MRI, the dissection plan was changed as intrafascial, interfascial, and extrafascial in the mp-MRI group. Two groups were compared in terms of age, prostate-specific antigen (PSA), Gleason sum scores and surgical margin positivity. There was no statistically significant difference between the two groups in terms of age, PSA, biopsy Gleason score, final pathological Gleason score and surgical margin positivity. mp-MRI changed the initial surgical plan in 18 of 30 patients (60%) in Group 1. In seventeen of these patients (56%) surgical plan was changed from non-nerve sparing to interfascial nerve sparing plan. In one patient dissection plan was changed to non-nerve sparing technique which had extraprostatic extension on final pathology. Surgical margin positivity was similar in Groups 1, and 2 (16% and 13%, respectively) although, Group 1 had higher number of high- risk patients. mp-MRI confirmed the primary tumour localisation in the final pathology in 27 of of 30 patients (90%). Preoperative mp-MRI effected the decision to perform a nerve-sparing technique in 56% of the patients in our study; moreover, changing the dissection plan from non-nerve-sparing technique to a nerve sparing technique did not increase the rate of surgical margin positivity.

Robotic surgery is becoming more and more commonplace. At the same time, so are complications, especially related to erectile function. The population being diagnosed with cancer is younger, with more aggressive cancers and higher expectations for good erectile function postoperatively. We conduct a retrospective analysis of literature over 20 years for Embase and Medline. Search terms used include (Robotic) AND (prostatectomy) AND (erectile function). There are a variety of multifactorial causes, resulting in worsening ED post-robotic radical prostatectomy; however, there are a number of treatments that can support this. There is much we can do to help prevent patients getting postoperative erectile dysfunction post-radical surgery. However, part of this is management of realistic patient expectations.

We assessed the probability of achieving continence and potency after robotic radical prostatectomy in elderly patients. The cohort included 1,436 robotic radical prostatectomy cases performed at our institution between 2003 and 2008. Continence (pad-free) and potency (erection sufficient for intercourse) at baseline and 1 year after surgery were evaluated by the UCLA-PCI questionnaire. Point estimates of the predicted probabilities of continence and potency for age 65, 70 and 75 years were calculated from multivariate logistic regression models adjusting for age, nerve sparing status, baseline International Prostate Symptom Score and baseline Sexual Health Inventory for Men score. Patients who were impotent before surgery or those who received hormones or radiation within 1 year after surgery were censored. Mean patient age was 60 years (range 38 to 85) with 25% older than 65 years and 77 (5%) 70 years old or older. Age (OR 0.97, p = 0.002), baseline I-PSS (OR 0.98, p = 0.02) and Sexual Health Inventory for Men scores (OR 1.02, p = 0.005) were independently associated with being pad-free. Age (OR 0.92, p <0.0001), baseline Sexual Health Inventory for Men score (OR 1.1, p <0.0001) and bilateral nerve sparing (OR 2.92, p <0.0001) were independently associated with achieving potency. Predicted probabilities (95% CI) of postoperative 1-year continence at age 65, 70 and 75 years were 0.66 (0.63, 0.69), 0.63 (0.57, 0.68) and 0.59 (0.52, 0.66), respectively. The corresponding probabilities of postoperative 1-year potency after bilateral nerve sparing were 0.66 (0.62, 0.71), 0.56 (0.49, 0.64) and 0.46 (0.36, 0.56). In our experience there is an acceptable probability of achieving continence and potency after robotic radical prostatectomy in selected elderly patients. 2010 American Urological Association Education and Research, Inc.

Prostate cancer is relatively common cancer occurring in males. Radical prostatectomy (RP) is the most effective treatment for a localized tumor but erectile dysfunction (ED) is common complication, even when bilateral nerve-sparing RP (BNSRP) is performed. Clinical trials have shown varied effectiveness of phosphodiesterase type-5 inhibitors (PDE5-Is) for treatment of post-BNSRP ED, but there remains controversy over the application of this treatment and no formal systematic review and meta-analysis for the use of PDE5-Is for this condition has been conducted. This review was to systematically assess the efficacy and safety of oral PDE5-Is for post-BNSRP ED. A database search was conducted to identify randomized controlled trials (RCTs). The comparative efficacy of treatments was analyzed by fixed or random effect modeling. Erectile function was measured using the International Index of Erectile Function (IIEF), Sexual Encounter Profile (SEP) question-2, 3 and the Global Assessment Question (GAQ). The rate and incidence of adverse events (AEs) were determined. The quality of included studies was appraised using the Cochrane Collaboration bias appraisal tool. Eight RCTs were included in the analyses. PDE5-Is were effective for treating post-BNSRP ED compared to placebo when erectile function was determined using the IIEF score [mean difference (MD) 5.63, 95% confidence interval (CI) (4.26–6.99)], SEP-2 [relative risk (RR) 1.63, 95% CI (1.18–2.25) ], SEP-3 [RR 2.00, 95% CI (1.27–3.15) ] and GAQ [RR 3.35, 95% CI (2.68–4.67) ]. The subgroup analysis could find a trend that longer treatment duration, higher dosage, on-demand dosing, sildenafil and mild ED are associated with more responsiveness to PDE5-Is. PDE5-Is were overall well tolerated with headache being the most commonly reported AE. Our data provides compelling evidence for the use of PDE5-Is as a primary treatment for post-BNSRP ED. However, further studies are required to optomize usage parameters

To investigate whether use of multiparametric magnetic resonance (MR) imaging-directed intraoperative frozen-section (IFS) analysis during nerve-sparing robot-assisted radical prostatectomy reduces the rate of positive surgical margins. This retrospective analysis of prospectively acquired data was approved by an institutional ethics committee, and the requirement for informed consent was waived. Data were reviewed for 134 patients who underwent preoperative multiparametric MR imaging (T2 weighted, diffusion weighted, and dynamic contrast-material enhanced) and nerve-sparing robot-assisted radical prostatectomy, during which IFS analysis was used, and secondary resections were performed when IFS results were positive for cancer. Control patients (n = 134) matched for age, prostate-specific antigen level, and stage were selected from a pool of 322 patients who underwent nerve-sparing robot-assisted radical prostatectomy without multiparametric MR imaging and IFS analysis. Rates of positive surgical margins were compared by means of the McNemar test, and a multivariate conditional logistic regression model was used to estimate the odds ratio of positive surgical margins for patients who underwent MR imaging and IFS analysis compared with control subjects. Eighteen patients who underwent MR imaging and IFS analysis underwent secondary resections, and 13 of these patients were found to have negative surgical margins at final pathologic examination. Positive surgical margins were found less frequently in the patients who underwent MR imaging and IFS analysis than in control patients (7.5% vs 18.7%, P = .01). When the differences in risk factors are taken into account, patients who underwent MR imaging and IFS had one-seventh the risk of having positive surgical margins relative to control patients (adjusted odds ratio: 0.15; 95% confidence interval: 0.04, 0.61). The significantly lower rate of positive surgical margins compared with that in control patients provides

Radical prostatectomy surgery (RP) is the gold standard for treatment of localized prostate cancer (PCa). Recently, emergence of minimally invasive techniques such as Laparoscopic Radical Prostatectomy (LRP) and Robot-Assisted Laparoscopic Radical Prostatectomy (RARP) has improved the outcomes for prostatectomy. However, it remains difficult for the surgeons to make informed decisions regarding resection margins and nerve sparing since the location of the tumor within the organ is not usually visible in a laparoscopic view. While MRI enables visualization of the salient structures and cancer foci, its efficacy in LRP is reduced unless it is fused into a stereoscopic view such that homologous structures overlap. Registration of the MRI image and peri-operative ultrasound image using a tracked probe can potentially be exploited to bring the pre-operative information into alignment with the patient coordinate system during the procedure. While doing so, prostate motion needs to be compensated in real-time to synchronize the stereoscopic view with the pre-operative MRI during the prostatectomy procedure. In this study, a point-based stereoscopic tracking technique is investigated to compensate for rigid prostate motion so that the same motion can be applied to the pre-operative images. This method benefits from stereoscopic tracking of the surface markers implanted over the surface of the prostate phantom. The average target registration error using this approach was 3.25+/-1.43mm.

Spouses of cancer patients play a crucial role in deciding on therapeutic choices. The aim of our study was to assess their role in counseling for radical prostatectomy. We analyzed 30 videotaped preoperative consultations prior to radical prostatectomy. Thereof, 14 included the patients' female partner and 16 took place without partner attendance. We performed quantitative and qualitative conversation analysis to compare both settings. Mean age of patients was 61 (47-73) years; 13% (4/30) did not have a partner. Duration of preoperative consultations was 20 (10-32) min. Physicians spoke most of the time (93%, range 71-99%), followed by patients (7%, range 1-20%) and spouses (2%, range 0-8%). Patients whose spouse was present at the consultation tended to have a more averted posture (50% vs. 25%, p = 0.04) and tended to speak less often (5% vs. 8%, p = 0.02). In 4 of 14 (29%) consultations, the spouses tended to be more dominant, speaking more frequently. Qualitative analysis showed several examples of emotional support and helpful contributions by spouses. Difference of opinion occurred when pros and cons of a nerve-sparing approach were discussed. The spouses' impact appeared to influence the final decision of men contemplating a nerve-sparing approach in 1 of 14 conversations. Spouses appear to play a complex and sometimes ambivalent role in counseling for radical prostatectomy. Especially when discussing a nerve-sparing approach, urologist should focus on the patients' true needs while interacting with both partners. Personalized decision aids might help to identify possible conflicts in advance.Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Orgasmic Dysfunction after Radical Prostatectomy

2017-01-01

In addition to urinary incontinence and erectile dysfunction, several other impairments of sexual function potentially occurring after radical prostatectomy (RP) have been described; as a whole, these less frequently assessed disorders are referred to as neglected side effects. In particular, orgasmic dysfunctions (ODs) have been reported in a non-negligible number of cases, with detrimental impacts on patients' overall sexual life. This review aimed to comprehensively discuss the prevalence and physiopathology of post-RP ODs, as well as potential treatment options. Orgasm-associated incontinence (climacturia) has been reported to occur in between 20% and 93% of patients after RP. Similarly, up to 19% of patients complain of postoperative orgasm-associated pain, mainly referred pain at the level of the penis. Moreover, impairment in the sensation of orgasm or even complete anorgasmia has been reported in 33% to 77% of patients after surgery. Clinical and surgical factors including age, the use of a nerve-sparing technique, and robotic surgery have been variably associated with the risk of ODs after RP, although robust and reliable data allowing for a proper estimation of the risk of postoperative orgasmic function impairment are still lacking. Likewise, little evidence regarding the management of postoperative ODs is currently available. In general, physicians should be aware of the prevalence of ODs after RP, in order to properly counsel all patients both preoperatively and immediately post-RP about the potential occurrence of bothersome and distressful changes in their overall sexual function.

One postulated cause of post-prostatectomy incontinence is urethral and bladder neck hypermobility. The objective of this study was to determine the magnitude of anatomical differences of urethral and bladder neck position at rest and with valsalva in continent and incontinent men post-prostatectomy based on dynamic MRI. All subjects underwent a dynamic MRI protocol with valsalva and non-valsalva images and a standard urodynamic evaluation. MRI measurements were taken at rest and with valsalva, including (1) bladder neck to sacrococcygeal inferior pubic point line (SCIPP), (2) urethra to pubis, and (3) bulbar urethra to SCIPP. Data were analyzed in SAS using two-tailed t tests. A total of 21 subjects (13 incontinent and 8 continent) had complete data and were included in the final analysis. The two groups had similar demographic characteristics. On MRI, there were no statistically significant differences in anatomic position of the bladder neck or urethra either at rest or with valsalva. The amount of hypermobility ranged from 0.8 to 2 mm in all measures. There were also no differences in the amount of hypermobility (position at rest minus position at valsalva) between groups. We found no statistically significant differences in bladder neck and urethral position or mobility on dynamic MRI evaluation between continent and incontinent men status post-radical prostatectomy. A more complex mechanism for post-prostatectomy incontinence needs to be modeled in order to better understand the continence mechanism in this select group of men. © 2013 Wiley Periodicals, Inc.

Objective The aim of this study was to analyze the impact of introduction of robot-assisted prostate surgery and its quality measures in Finland from 2008 to 2012. Materials and methods Registry data were collected for time trends and national distribution of prostate cancer surgery in Finland, while preoperative, operative and follow-up data were collected for quality measures. Results The number and proportion of robot-assisted laparoscopic radical prostatectomies (RALPs) increased rapidly and they accounted for 68% of all radical prostatectomies in 2012. The number of centers performing prostatectomies diminished from 25 to 20 at the expense of low-volume centers. In total, 1996 patients were operated on in the four RALP centers in 2008-2012. As anticipated, the learning curve was uniform between the centers, as were mean blood loss (212 ml), hospitalization (1.8 days) and catheterization times (10.6 days). At 3 and 12 months, 49.4% and 71.2% of patients, respectively, were totally continent (no pads). After unilateral nerve-sparing surgery, 9.9% and 5.1% had partial or normal erection at 3 months postoperatively and 14.8% and 20.4% at 12 months, respectively. If bilateral nerve sparing was done, the figures were 13.0% and 13.5% at 3 months and 14.6% and 34.9% at 12 months. Clavien-Dindo grade 3, 4 or 5 complications were seen in 0.3%, 0.3% and 0.1% of patients, respectively. Limitations of the study include non-standardized collection of outcome parameters. Conclusions This report shows that the main impact of adoption of RALP on a national level was rapid spontaneous centralization of prostate cancer surgery. The main advantages of minimally invasive prostatectomy, i.e. low blood loss and short hospitalization, are easily achieved, while continuous effort is necessary for improvements in surgical outcomes.

Sexual dysfunction is common after surgery for prostate cancer. The aetiology of changes in sexual potency after radical prostatectomy is probably multifactorial, including neurogenic, vascular and psychosexual factors. A prospective study was designed to investigate haemodynamic and psychosexual changes before and after radical retropubic prostatectomy (RRP) for organ-confined prostate cancer. Penile haemodynamic evaluation and an assessment of sexual excitement were performed preoperatively and 3 months after RRP by colour Doppler ultrasonography (CDU) with visual erotic stimulation combined with a single intracavernous injection of a mixture of papaverine/phentolamine. Questionnaires on sexual function [International Index of Erectile Function (IIEF)], general health and quality of life were sent to the patients preoperative, 3 months and 5 years after operation. Forty-eight men participated in the study. Mean age was 62.6 years (range 55-69). CDU did not show any significant reduction in mean peak systolic flow velocity and mean resistance index. From the men who preoperatively had normal arterial inflow 18% developed arteriogenic insufficiency. Some form of veno-occlusive insufficiency and low resistance indices were already present in the majority of normal potent men preoperatively. Surgical technique did not influence penile arterial blood flow after the operation. Three months and 5 years postoperatively, there was a highly significant reduction in erectile function, intercourse satisfaction, overall satisfaction, orgasmic function and sexual desire. However, with respect to the outcome at 3 months there was a significant improvement of orgasmic function 5 years after operation, especially after a bilateral nerve sparing procedure. Erections sufficient for vaginal penetration (questions 3 and 4 of the IIEF, score >or=8) improved from 2% to 11% 3 months and 5 years after RRP respectively. Total IIEF score was significantly better after a bilateral nerve-sparing

OBJECTIVE To evaluate associations between baseline characteristics, nerve-sparing (NS) status and return of continence, as a relationship may exist between return to continence and preservation of the neurovascular bundles for potency during radical prostatectomy (RP). PATIENTS AND METHODS The study included 592 consecutive robotic RPs completed between 2002 and 2007. All data were entered prospectively into an electronic database. Continence data (defined as zero pads) was collected using self-administered validated questionnaires. Baseline characteristics (age, International Index of Erectile Function [IIEF-5] score, American Urological Association symptom score, body mass index [BMI], clinical T-stage, Gleason score, and prostate-specific antigen level), NS status and learning curve were retrospectively evaluated for association with overall continence at 1, 3 and 12 months after RP using univariate and multivariable methods. Any patient taking preoperative phosphodiesterase inhibitors was excluded from the postoperative analysis. RESULTS Complete data were available for 537 of 592 patients (91%). Continence rates at 12 months after RP were 89.2%, 88.9% and 84.8% for bilateral NS, unilateral NS and non-NS respectively (P = 0.56). In multivariable analysis age, IIEF-5 score and BMI were significant independent predictors of continence. Cavernosal NS status did not significantly affect continence after adjusting for other co-variables. CONCLUSION After careful multivariable analysis of baseline characteristics age, IIEF-5 score and BMI affected continence in a statistically significant fashion. This suggests that baseline factors and not the physical preservation of the cavernosal nerves predict overall return to continence. PMID:21244602

To characterize changes in indices of urinary function in prostatectomy patients with presurgical voiding symptoms. A retrospective analysis of our prostate cancer database identified robot-assisted radical prostatectomy patients between April 2007 and December 2011 who completed pre- and postsurgical (24 months) Expanded Prostate Cancer Index Composite-26 surveys. Gleason score, margins, D'Amico risk, prostate-specific antigen, radiotherapy, and nerve-sparing status were tabulated. Survey questions addressed urinary irritation/obstruction, incontinence, and overall bother. Responses were averaged to calculate a urinary sum (US) score. Patients were stratified according to the severity of their baseline urinary bother (UB), and changes in urinary indices determined at 24 months. A total of 737 patients were included. Postsurgical improvement in urinary obstruction, bother, and sum score was related to baseline UB (P <.001). Men with severe baseline bother had the greatest improvement in US (+9.3), whereas those with asymptomatic baseline UB experienced a decline in US (-2.8). All patients experienced a decline in urinary incontinence of 6.3-8.3 that was independent of baseline bother (P = .507). Patients with severe UB experienced positive outcomes, whereas those at asymptomatic baseline experienced negative US outcomes. Negative urinary incontinence outcomes were unrelated to baseline UB. Age, radiotherapy, and nerve-sparing status were not associated with improved UB (P = .029). However, baseline UB was significantly associated with improvement in postsurgical UB (P = .001). Baseline UB is a predictor of postsurgical improvement in urinary function. These data are helpful when counseling a subset of robot-assisted laparoscopic radical prostatectomy patients with severe preoperative urinary symptoms. Copyright © 2015 Elsevier Inc.

Radical hysterectomy with pelvic lymphadenectomy (RHL) for cervical cancer causes damage to the autonomic nerves, which are responsible for increased vaginal blood flow during sexual arousal. The aim of the study of which we now report preliminary data was to determine whether a nerve-sparing technique leads to an objectively less disturbed vaginal blood flow response during sexual stimulation. Photoplethysmographic assessment of vaginal pulse amplitude (VPA) during sexual stimulation by erotic films was performed. Subjective sexual arousal was assessed after each stimulus. Thirteen women after conventional RHL, 10 women after nerve-sparing RHL, and 14 healthy premenopausal women participated. Data were collected between January and August 2006. The main outcome measure was the logarithmically transformed mean VPA. To detect statistically significant differences in mean VPA levels between the three groups, a univariate analysis of variance was used. Mean VPA differed between the three groups (P= 0.014). The conventional group had a lower vaginal blood flow response than the control group (P= 0.016), which tended also to be lower than that of the nerve-sparing group (P= 0.097). These differences were critically dependent on baseline vaginal blood flow differences between the groups. The conventional group follows a vaginal blood flow pattern similar to postmenopausal women. Conventional RHL is associated with an overall disturbed vaginal blood flow response compared with healthy controls. Because it is not observed to the same extent after nerve-sparing RHL, it seems that the nerve-sparing technique leads to a better overall vaginal blood flow caused by less denervation of the vagina.

Background Robot-assisted radical prostatectomy (RARP) is increasingly used worldwide, but comparisons of perioperative, functional, and oncologic outcomes among RARP, laparoscopic radical prostatectomy (LRP), and open radical prostatectomy (ORP) remain inconsistent. Material/Methods Systematic literature searches were conducted using EMBASE, PubMed, the Cochrane Library, CNKI, and Science Direct/Elsevier up to April 2017. A meta-analysis was conducted using Review Manager and Stata software. Results We included 33 studies. Meta-analysis revealed that blood loss, transfusion rate, and positive surgical margin (PSM) rate were significantly lower following RARP compared with LRP (SMD (95% confidence interval [CI]) 0.31 [0.01, 0.61]; combined ORs (95% CI) 5.32 [1.29, 21.98]; 1.27 [1.10, 1.46]) and ORP (SMD (95% CI) 0.75 [0.30, 1.21]; and combined ORs (95% CI) 3.44 [1.21, 9.79]); positive surgical margin (PSM) rates were significantly lower following RARP compared with LRP (combined ORs (95% CI) 1.27 [1.10, 1.46]), but not ORP. Operation time was also shorter for RARP than for LRP. The rates of nerve-sparing, recovery of complete urinary continence, and recovery of erectile function were significantly higher following RARP compared with LRP (combined ORs (95% CI) 0.55 [0.31, 0.95]; 0.66 [0.55, 0.78]; 0.46 [0.30, 0.71]) and ORP (combined ORs (95% CI) 0.36 [0.21, 0.63]; 0.33 [0.15, 0.74]; 0.65 [0.37, 1.14]). Conclusions This meta-analysis demonstrates that RARP results in better overall outcomes than LRP and ORP in terms of blood loss, transfusion rate, nerve sparing, urinary continence and erectile dysfunction recovery, and suggests that RARP offers better results than LRP and ORP in treatment of prostate cancer. However, studies with larger sample sizes and long-term results are needed. PMID:29332100

For men with high-volume or high-grade prostate cancer, wide excision of the ipsilateral neurovascular bundle is commonly performed. The concept of nerve reconstruction is intriguing as a feasible approach to preserve sexual function (SF). We sought to evaluate the functional, pathologic, and oncologic outcomes of men who underwent robot-assisted sural-nerve graft (SNG) interposition. Between February 2003 and May 2007, 1175 consecutive men underwent robot-assisted laparoscopic radical prostatectomy (RLRP). Database analysis identified 27 men who had SNG: 4 bilateral (BL) and 23 unilateral (UL). SF was prospectively evaluated preoperatively and at 1, 3, 6, 12, and 24 months postoperatively using validated questionnaires. Positive surgical margins (PSMs), biochemical recurrence (BCR), and potency were evaluated. Compared with RLRP patients without SNG, patients with SNG were younger (57.2 v 61.8 years, P=0.02), had a higher Gleason score (P=0.02), and had a higher clinical and pathologic stage (P<0.001 for both). Mean surgical time was significantly longer (349 v 195 min, P<0.001) in patients with SNG. With a mean follow-up of 26.1 months, 11 (47.8%) patients with UL-SNG and zero men with BL-SNG regained potency. No significant difference in SF was observed between UL nerve sparing and no SNG (56%) compared with UL nerve sparing with UL-SNG (P=0.44). Rates of return-to-baseline SF (RTB-SF) at 6, 12, and 24 months were 11%, 36% and 45% for UL-SNG, respectively, which were also comparable to UL nerve sparing only (P>0.05). No patient (0%) in the BL-SNG group ever achieved RTB-SF status at any time point. PSMs were observed in 37% (10/27) of all patients. BCR occurred in nine patients (33.3%), seven of whom had PSM (78%); treatment failure occurred within 6 months of surgery, necessitating androgen deprivation therapy. Despite optimism regarding SNG, long-term functional outcomes have been disappointing, particularly for BL nerve interposition. UL-SNG functional

Phosphodiesterase type-5 inhibitors (PDE5-Is) have been recommended as first line therapy for erectile dysfunction for patients received nerve-sparing radical prostatectomy for prostate cancer. We examed the efficiency of PDE5-Is and considered the optimal application. Systematic search of PubMed, Embase and the Cochrane Library was performed to identify all the studies. We identified 103 studies including 3175 patients, of which 14 were recruited for systematic review. Compared with placebo, PDE5-Is significantly ameliorated the International Index of Erectile Function-Erectile Function domain score (IIEF) scores (MD 4.89, 95% CI 4.25-5.53, p < 0.001). By network meta-analysis, sildenafil seems to be the most efficiency with a slightly higher rate of treatment-emergent adverse events (TEATs), whereas tadalafil had the lowest TEATs. In terms of IIEF scores, regular regimen was remarkably better than on-demand (MD 3.28, 95% CI 1.67-4.89, p < 0.001). Regular use was not associated with higher proportion of patients suffering TEATs compared with on-demand (RR 1.02, 95% CI 0.90-1.16, p = 0.72). Compared with placebo, PDE5-Is manifested significantly improved treatment outcomes. Overall, regular regimen demonstrated statistically pronounced better potency than on-demand. Coupled with the comparable rate of side effects, these findings support the regular delivery procedure to be a cost-effective option for patients.

In the present study, we review current literature and based on our experience, we present the anatomical landmarks of open and laparoscopic/endoscopic radical prostatectomy. A thorough literature search was performed with the Medline database on the anatomy and the nomenclature of the structures surrounding the prostate gland. The correct handling of puboprostatic ligaments, external urethral sphincter, prostatic fascias and neurovascular bundle is necessary for avoiding malfunction of the urogenital system after radical prostatectomy. When evaluating new prostatectomy techniques, we should always take into account both clinical and final oncological outcomes. The present review adds further knowledge to the existing "postprostatectomy anatomical hazard" debate. It emphasizes upon the role of the puboprostatic ligaments and the course of the external urethral sphincter for urinary continence. When performing an intrafascial nerve sparing prostatectomy most urologists tend to approach as close to the prostatic capsula as possible, even though there is no concurrence regarding the nomenclature of the surrounding fascias and the course of the actual neurovascular bundles. After completion of an intrafascial technique the specimen does not contain any periprostatic tissue and thus the detection of pT3a disease is not feasible. This especially becomes problematic if the tumour reaches the resection margin. Nerve sparing open and laparoscopic radical prostatectomy should aim in maintaining sexual function, recuperating early continence after surgery, without hindering the final oncological outcome to the procedure. Despite the different approaches for radical prostatectomy the key for better results is the understanding of the anatomy of the bladder neck and the urethra.

To evaluate the pathologic and functional outcomes of patients with bilateral interfascial (IF) or extrafascial nerve-sparing (EF-NSP) techniques. It is believed that the IF-NSP technique used during robotic-assisted radical prostatectomy (RARP) spares more nerve fibers, while EF dissection may lower the risk for positive surgical margins (PSM). A prospective database was analyzed for RARP patients with bilateral IF- or EF-NSP technique. Collected parameters included age, body mass index, prostate-specific antigen, clinical and pathologic Gleason score and stage, estimated blood loss, operative time, and PSM characteristics. Functional outcomes were evaluated with the use of the University of California Los Angeles Prostate Cancer Index questionnaire. Men receiving postoperative hormonal or radiation therapy were excluded from sexual function analysis. A total of 110 and 703 cases with bilateral EF- and IF-NSP, respectively, were analyzed. EF-NSP patients had higher prostate-specific antigen, clinical, pathologic stage, and pathologic Gleason score. PSM rate did not achieve statistically significant difference between groups. There was a trend toward lower pT3-PSM in the EF group (51% vs 28%; P = .08). Mid- and posterolateral PSM location were lower in the EF-NSP group, 11% vs 37% and 11% vs 29%, respectively (P < .001). The IF-NSP group patients achieved statistically significant better sexual function (P = .02) and potency rates (P = .03) at 12 months after RARP. In lower risk patients, bilateral IF-NSP technique does not result in significantly higher PSM rates. EF-NSP appears to reduce posterolateral and mid-prostate PSM. Men with bilateral IF-NSP demonstrate significantly better sexual function outcomes.

ABSTRACT Introduction Robotic-assisted radical prostatectomy (RAP) is the dominant minimally invasive surgical treatment for patients with localized prostate cancer. The introduction of robotic assistance has the potential to improve surgical outcomes and reduce the steep learning curve associated with conventional laparoscopic radical prostatectomy. The purpose of this video is to demonstrate the early retrograde release of the neurovascular bundle without open the endopelvic fascia during RAP. Materials and Methods A 51-year old male, presenting histological diagnosis of prostate adenocarcinoma, Gleason 6 (3+3), in 4 cores of 12, with an initial PSA=3.41ng/dl and the digital rectal examination demonstrating a prostate with hardened nodule in the right lobe of the prostate base (clinical stage T2a). Surgical treatment with the robot-assisted technique was offered as initial therapeutic option and the critical technical point was the early retrograde release of the neurovascular bundle with endopelvic fascia preservation, during radical prostatectomy. Results The operative time was of 89 minutes, blood loss was 100ml. No drain was left in the peritoneal cavity. The patient was discharged within 24 hours. There were no intraoperative or immediate postoperative complications. The pathological evaluation revealed prostate adenocarcinoma, Gleason 6, with free surgical margins and seminal vesicles free of neoplastic involvement (pathologic stage T2a). At 3-month-follow-up, the patient lies with undetectable PSA, continent and potent. Conclusion This is a feasible technique combining the benefits of retrograde release of the neurovascular bundle, the preservation of the pubo-prostatic collar and the preservation of the antero-lateral cavernous nerves.

The aim of this study was to assess the capability of a 3D isotropic MRI T2-weighted sequence (3D T2 ISO) in the depiction of changes of neurovascular bundles (NVBs) after bilateral nerve-sparing radical retropubic prostatectomy (RRP). Furthermore, our aim was also to introduce a new MRI classification score of the NVB alteration patterns using the International Index Erectile Function Five-Item (IIEF-5) score as standard of reference. Fifty-three consecutive patients were postoperatively submitted to two MR examinations, including both 2D TSE T2-weighted (2D T2) and 3D T2 ISO sequences. Image findings were scored using a relative five-point classification and correlated with the postoperative IIEF-5 score. Radiologists attributed 13.2% of patients to class 0, 11.3% to class I, 34% to class II, 24.5% to class III, and 16.9% to class IV. With 3D T2 ISO images, the same radiologists determined 43.3% class 0, 32% class I, 11.4% class II, 7.5% class III, and 5.7% class IV. In all cases, the correlation and regression analysis between the 3D T2 ISO and IIEF-5 score resulted in higher coefficients values. The 3D sequence correlated most closely with patients' grading of erectile function.

Neglected side effects after radical prostatectomy have been previously reported. In this context, the prevalence of penile morphometric alterations has never been assessed in robot-assisted radical prostatectomy series. We aimed to assess prevalence of and predictors of penile morphometric alterations (i.e. penile shortening or penile morphometric deformation) at long-term follow-up in patients submitted to either robot-assisted (robot-assisted radical prostatectomy) or open radical prostatectomy. Sexually active patients after either robot-assisted radical prostatectomy or open radical prostatectomy prospectively completed a 28-item questionnaire, with sensitive issues regarding sexual function, namely orgasmic functioning, climacturia and changes in morphometric characteristics of the penis. Only patients with a post-operative follow-up ≥ 24 months were included. Patients submitted to either adjuvant or salvage therapies or those who refused to comprehensively complete the questionnaire were excluded from the analyses. A propensity-score matching analysis was implemented to control for baseline differences between groups. Logistic regression models tested potential predictors of penile morphometric alterations at long-term post-operative follow-up. Overall, 67 (50%) and 67 (50%) patients were included after open radical prostatectomy or robot-assisted radical prostatectomy, respectively. Self-rated post-operative penile shortening and penile morphometric deformation were reported by 75 (56%) and 29 (22.8%) patients, respectively. Rates of penile shortening and penile morphometric deformation were not different after open radical prostatectomy and robot-assisted radical prostatectomy [all p > 0.5]. At univariable analysis, self-reported penile morphometric alterations (either penile shortening or penile morphometric deformation) were significantly associated with baseline international index of erectile function-erectile function scores, body mass index, post

tumour volume do not (P < 0.05). Attempt at nerve sparing had no adverse effect on achieving a uPSA of < or = 0.01 ng/ml at 3 months. uPSA can be used as an early end-point in the analysis of oncological outcomes after radical prostatectomy. It is one of many measures that can be used in calculating a surgeon's learning curve for laparoscopic radical prostatectomy and in bench-marking performance. With experience, a surgeon can achieve in excess of an 80% chance of obtaining a uPSA nadir of < or = 0.01 ng/ml at 3 months after laparoscopic RRP for a British population. This is equivalent to most published open series.

Techniques for minimally invasive radical prostatectomy (RP) have been carefully reviewed by surgical teams worldwide in order to identify possible weaknesses and facilitate further improvement in their overall performance. The initial plan of action has been to carefully study the best-practice techniques for open RP in order to reproduce and standardize performance from the laparoscopic perspective. Similar to open surgery, the learning curve of minimally invasive RP has been well documented in terms of objective evaluation of outcomes for cancer control and functional results. Natural orifice transluminal endoscopic surgery (NOTES) and laparoendoscopic single-site surgery (LESS) have recently gained momentum as feasible techniques for minimal access urological surgery. NOTES-LESS drastically limit the surgeon's ability to choose the site of entry for operative instruments; therefore, the advantages of NOTES-LESS are gained with the understanding that the surgical procedure is more technically challenging. There are several key elements in RP techniques (in particular, dorsal vein control, apex exposure and cavernosal nerve sparing) that can have significant implications on oncologic and functional results. These steps are hard to perform in a limited working field. LESS radical prostatectomy can clearly be facilitated by using robotic technology.

Orgasm-Associated Incontinence (OAI) or climacturia has been observed in male patients maintaining sexual potency after radical prostatectomy and cystectomy. We investigated the incidence and video-urodynamic aspects of this event in continent and potent patients after bladder neck-sparing (BNS) radical prostatectomy (RP). Comparing functional and morphological aspects between climacturic and non-climacturic patients to identify a possible explanation of this unusual kind of leakage that could seriously impact the sexual life after surgery. In a pool of 84 men, potent and continent at least 1 year after BNS RP, 24 (28.6%) reported climacturia and 7 agreed to undergo video-urodynamic evaluation (group 1), which was performed also in 5 controls (group 2). Those 12 men were also evaluated with 24-hour pad test, 5-item International Index of Erectile Function and International Prostate Symptom Score questionnaires. Functional urethral length (FUL) was significantly lower in the climacturia group (P=0.02) and time to continence recovery was significantly longer (P=0.05). No other significant differences were found between the two groups. The radiological appearance of the vesicourethral junction at voiding cystourethrography was similar. To the best of our knowledge, this is the first functional and morphological evaluation of climacturia after RP. In our experience, this event is indirectly associated with a reduced FUL in the sphincter area, although both patients and controls were continent during daily activities. BNS technique seems to reduce time to continence recovery, although climacturic patients need longer time than control patients. Since in our series no rigidity of the vesicourethral anastomosis was radiographically evident, we believe that differences in FUL could explain OAI. Anatomical difference in membranous urethra length could explain the occurrence of this symptom in patients treated with the same surgical technique. © 2012 International Society

We report a 1-year update of functional urinary and sexual recovery, oncologic outcomes and postoperative complications in patients who completed a randomized controlled trial comparing posterior (Retzius sparing) with anterior robot-assisted radical prostatectomy. A total of 120 patients with clinically low-intermediate risk prostate cancer were randomized to undergo robot-assisted radical prostatectomy via the posterior and anterior approach in 60 each. Surgery was performed by a single surgical team at an academic institution. An independent third party ascertained urinary and sexual function outcomes preoperatively, and 3, 6 and 12 months after surgery. Oncologic outcomes consisted of positive surgical margins and biochemical recurrence-free survival. Biochemical recurrence was defined as 2 postoperative prostate specific antigen values of 0.2 ng/ml or greater. Median age of the cohort was 61 years and median followup was 12 months. At 12 months in the anterior vs posterior prostatectomy groups there were no statistically significant differences in the urinary continence rate (0 to 1 security pad per day in 93.3% vs 98.3%, p = 0.09), 24-hour pad weight (median 12 vs 7.5 gm, p = 0.3), erection sufficient for intercourse (69.2% vs 86.5%) or postoperative Sexual Health Inventory for Men score 17 or greater (44.6% vs 44.1%). In the posterior vs anterior prostatectomy groups a nonfocal positive surgical margin was found in 11.7% vs 8.3%, biochemical recurrence-free survival probability was 0.84 vs 0.93 and postoperative complications developed in 18.3% vs 11.7%. Among patients with clinically low-intermediate risk prostate cancer randomized to anterior (Menon) or posterior (Bocciardi) approach robot-assisted radical prostatectomy the differences in urinary continence seen at 3 months were muted at the 12-month followup. Sexual function recovery, postoperative complication and biochemical recurrence rates were comparable 1 year postoperatively. Copyright © 2018

Preservation of prostatic nerves is critical to recovery of a man’s sexual potency after radical prostatectomy. A real-time imaging method of prostatic nerves will be helpful for nerve-sparing radical prostatectomy (NSRP). Polarization-sensitive optical coherence tomography (PS-OCT), which provides both structural and birefringent information of tissue, was applied for detection of prostatic nerves in both rat and human prostate specimens, ex vivo. PS-OCT imaging of rat prostate specimens visualized highly scattering and birefringent fibrous structures superficially, and these birefringent structures were confirmed to be nerves by histology or multiphoton microscopy (MPM). PS-OCT could easily distinguish these birefringent structures from surrounding other tissue compartments such as prostatic glands and fats. PS-OCT imaging of human prostatectomy specimens visualized two different birefringent structures, appearing fibrous and sheet-like. The fibrous ones were confirmed to be nerves by histology, and the sheet-like ones were considered to be fascias surrounding the human prostate. PS-OCT imaging of human prostatectomy specimens along the perimeter showed spatial variation in the amount of birefringent fibrous structures which was consistent with anatomy. These results demonstrate the feasibility of PS-OCT for detection of prostatic nerves, and this study will provide a basis for intraoperative use of PS-OCT. PMID:27699090

Purpose To determine retrospectively the prognostic factors for urinary incontinence following robot-assisted radical prostatectomy (RARP). Methods Altogether, 180 patients with localized prostate cancer underwent RARP (same surgeon). Preoperative physical status, disease characteristics, laboratory findings, and surgical technique were recorded and the patients checked 1, 6, 12, and 24 months after RARP regarding their contribution to predicting post-prostatectomy urinary incontinence (PPI). Results Overall, 114 (63.3%) patients had PPI 1 month after RARP and 19 patients (16.0%) at 24 months. Univariate analysis showed that age was a significant factor for predicting PPI at 1 month. PPI predictors at 24 months were age, body mass index, preoperative serum albumin level, previous transurethral resection of the prostate, total operative time, and bladder neck sparing. Multivariate analysis indicated that age and total operative time were significant predictors. Conclusion Older age and longer operative time were highly relevant to short- and long-term PPI occurrence after RARP.

To evaluate the trifecta outcomes following robotic-assisted laparoscopic prostatectomy (RALP) and compare the results applying definitions of continence and potency as reported in the literature vs validated questionnaire. The trifecta rate of achieving continence, potency, and undetectable prostate-specific antigen (PSA) following radical prostatectomy has been estimated to be approximately 60% at 1-2 years in open radical prostatectomy series. The definitions of continence and potency were not standardized, which poses difficulty in comparing published results. A prospective, institutional RALP database was analyzed for preoperatively continent and potent men with >/= 1 year follow-up after bilateral nerve-sparing surgery. Continence and potency were evaluated preoperatively and at 3, 6, 12, and 24 months after surgery by surgeon interview (subjective) and using University of California Los-Angeles Prostate Cancer Index self-administered questionnaire (objective). Biochemical recurrence was defined as a detectable (> 0.05 ng/mL), increasing PSA on 2 consecutive tests. Among 1362 consecutive RALPs, 380 patients were preoperatively potent and continent underwent surgery with bilateral nerve-sparing technique and had sufficient follow-up. Trifecta rates applying subjective continence and potency definitions were 34%, 52%, 71%, and 76% at 3, 6, 12, and 24 months, respectively. The corresponding trifecta rates using objective continence and potency definitions stood at 16%, 31%, 44%, and 44%. The difference was statistically significant at each time point (P < .0001). RALP provides trifecta outcome rates comparable to open surgery. The outcome rates vary significantly depending on the tools used for continence and potency evaluation.

The purpose of this study was to determine the feasibility of performing laparoscopic radical prostatectomy in a canine model. Laparoscopic radical prostatectomy was performed on six adult male canines. A new endoscopic needle driver was used to construct a secure vesicourethral anastomosis. Average operative time required to complete the procedure was 304 min (range 270-345 min). Dissection of the prostate gland took an average of 67 min (range 35-90 min), and construction of the vesicourethral anastomosis took 154 min (rage 80-240 min). There were no intraoperative complications and only one postoperative complication (anastomotic leak). Five of the six animals recovered uneventfully from the procedure, and their foley catheters were removed 10-14 days postoperatively after a retrograde cystourethrogram demonstrated an intact vesicourethral anastomosis. Four (80%) of the surviving animals were clinically continent within 10 days after catheter removal. Post mortem examination confirmed that the vesicourethral anastomosis was intact with no evidence of urine extravasation. These data demonstrate the feasibility of laparoscopic radical prostatectomy in a canine model, and suggest that additional work with this technique should be continued to develop its potential clinical application.

There have been few reports on health-related quality of life (HRQOL) after laparoscopic radical prostatectomy (LRP) in Japanese patients. The aim of this study is to assess changes in HRQOL during 36 months after LRP compared with retropubic radical prostatectomy (RRP). The subjects were 105 consecutive patients treated with LRP between 2011 and 2012. HRQOL was evaluated using the International Prostate Symptom Score (IPSS), Medical Outcome Study 8-Items Short Form Health Survey (SF-8), and Expanded Prostate Cancer Index Composite (EPIC) at baseline and 1, 3, 6, 12 and 36 months after surgery. These results were compared with data for 107 consecutive patients treated with RRP between 2005 and 2007. The comparison between LRP and RRP was examined at every time point by Mann-Whitney U-test and chi-square test. Multiple linear regression analysis was used to identify independent factors related to the urinary domain in EPIC. The IPSS change was similar in both groups. The LRP group had a better SF-8 mental component summary score at baseline and a better SF-8 physical component summary score at 1 month after surgery. In EPIC, urinary function and bother were worse after LRP, but improved at 12 months and did not differ significantly from those after RRP; however, these factors then worsened again at 36 months after LRP. Urinary incontinence was also worse at 36 months after LRP, compared to RRP. In patients treated with nerve-sparing surgery, urinary function and urinary incontinence were similar and good at 12 and 36 months in both groups. Bowel function and bother, and sexual function and bother were similar in both groups and showed no changes from 12 to 36 months. Age and salvage radiotherapy were independent predictors of incontinence (daily use of two or more pads) in multivariate analysis. Surgical procedure was not an independent factor for incontinence, but incontinence defined as use of one pad or more was associated with the surgical procedure

Herein we describe our experience with a bone-anchored sling using a suture anchor and polypropylene mesh for the treatment of post-radical prostatectomy urinary incontinence. Eight patients with urinary incontinence as a result of intrinsic sphincter deficiency after radical prostatectomy were included in the analysis. The procedure involved piercing the pubic bone with a bone drill, inserting the suture anchor and fixing a soft or rigid polypropylene mesh to press firmly on the bulbar urethra. Urinary incontinence was significantly improved according to changes in the daily number of pads used at 1, 3 and 6 months postoperatively in comparison with preoperatively. However, no meaningful improvement at 6 months postoperatively was seen with the soft mesh. Complications included perineal pain in four cases, but pain control was achieved using non-steroidal anti-inflammatory drugs. The bone-anchored sling with a suture anchor and polypropylene mesh appears to be safe and effective for the treatment of post-radical prostatectomy urinary incontinence. Soft mesh appears inappropriate as material for the bone-anchored sling because of the progressive likelihood of worsened urinary incontinence. © 2012 The Japanese Urological Association.

Anatomical radical prostatectomy was introduced in the early 1980s by Walsh and Donker. Elucidation of key anatomical structures led to a significant reduction in the morbidity of this procedure. The strive to achieve similar oncological and functional results to this gold standard open procedure but with further reduction of morbidity through a minimally invasive access led to the establishment of laparoscopic prostatectomy. However, this procedure is complex and difficult and is associated with a long learning curve. The technical advantages of robotically assisted surgery coupled with the intuitive handling of the device led to increased precision and shortening of the learning curve. These main advantages, together with a massive internet presence and aggressive marketing, have resulted in a rapid dissemination of robotic radical prostatectomy and an increasing patient demand. However, superiority of robotic radical prostatectomy in comparison to the other surgical therapeutic options has not yet been proven on a scientific basis. Currently robotic-assisted surgery is an established technique and future technical improvements will certainly further define its role in urological surgery. In the end this technical innovation will have to be balanced against the very high purchase and running costs, which remain the main limitation of this technology.

Retzus-sparing robotic-assisted radical prostatectomy(RARP) is a newly approach that preserve the Retzus structures and provide better recovery of continence and erectile function. In Brazil, this approach has not yet been pre¬viously reported. Our goal is to describe Step-by-Step the Retzus-sparing RARP surgical technique and report our first Brazilian experience. We present a case of a 60-year-old white man with low risk prostate cancer. Surgical materials were four arms Da Vinci robotic platform system, six transperitoneal portals, two prolene wires and Polymer Clips. This surgical tech¬nique was step-by-step described according to Galfano et al. One additional step was added as a modification of Galfano et al. Primary technique description: The closure of the Denovellier fascia. We have operated one patient with this technique. The operative time was 180minutes, console time was135 min, the blood loss was 150ml, none perioperative or postoperative complications was found, hospital stay of 01 day. The anatomopathological classification revealed a pT2aN0M0 specimen with free surgical margins. The patient achieved continence immediately after bladder stent retrieval. Full erection reported after 30 days of surgery. Retzus-sparing RARP approach is feasible and reproducible. However, further comparative studies are neces¬sary to demonstrate potential benefits in continence and sexual outcomes over the standard approaches.

The aim of this study was to compare oncological and functional outcomes of pure laparoscopic radical prostatectomy (LRP) and robotic-assisted laparoscopic radical prostatectomy (RALRP) performed by a single surgeon. In total, 327 consecutive patients with prostate cancer who underwent radical prostatectomy (144 with LRP and 183 with RALRP) were enrolled. No significant differences were found in prostate-specific antigen level, biopsy Gleason score, clinical T stage or D'Amico risk stratification between the two groups. The operating time was longer in the LRP group (p < 0.001). The RALRP group patients had significantly lower postoperative pain numerical rating scale (NRS) (p = 0.016) and catheter duration (p < 0.001). There were no differences in pathological Gleason score, pathological T stage or positive surgical margin rate. No differences were found in biochemical recurrence-free survival. Postoperative pad-free continence rates revealed a more rapid recovery in the RALRP group, but rates at 12 months were not significantly different. Multivariate analysis showed that the type of surgery was a strong independent factor to predict early postoperative pad use. Postoperative potency rates were not significantly different at 3, 6 and 12 months in patients who underwent nerve-sparing procedures. LRP and RALRP performed by a single surgeon yielded similar results in terms of safety and oncological outcomes. More favorable outcomes were noted in operating time, pain NRS and catheter duration, as well as urinary continence recovery time. Therefore, RALRP showed more favorable components in terms of postoperative quality of life than LRP.

Outcomes of continence, erectile function, and oncologic control are well-described in isolation especially for the retropubic open approach. However, only few series have yet reported combined results after radical prostatectomy. To determine the proportion of men who are continent, potent, and cancer-free (trifecta rate) 2 years after robot-assisted laparoscopic radical prostatectomy (RALRP). We included patients who underwent a RALRP at our department and who were followed during at least 2 years. Men who were impotent or incontinent before the surgery were excluded from the analysis. Overall, 500 men were included. All patients prospectively completed validated questionnaires (IIEF-5, ICS) before the medical visit and concerning their voiding and sexual disorders, preoperatively, 3, 6, 12, 18, and 24 months after RALRP. Biochemical recurrence was defined as any detectable serum PSA (≥ 0.2 ng/ml). The study end point was the trifecta rate (cancer control, continence, and potency) at 2 years of the surgery. Predictive factors of the trifecta outcome were assessed in univariate and multivariate analyses. Median age and PSA level were 62.2 years and 9.7 ng/mL. A trifecta outcome was achieved in 44% and 53% of men at 12 and 24 months, respectively. The 2-year trifecta rate reached 62% in men undergoing bilateral nerve-sparing surgery and 71% in men < 60 years. Age < 60 years, PSA level < 10 ng/ml, organ-confined disease, and bilateral nerve-sparing procedure were significantly associated with the 2-year trifecta outcome. Two years after RALRP, the trifecta outcome is achieved in 53% of preoperatively potent and continent men. Copyright © 2013 Elsevier Inc. All rights reserved.

Background Prostate cancer is the second most common type of cancer in Canadian men. Radical prostatectomy is one of the treatment options available, and involves removing the prostate gland and surrounding tissues. In recent years, surgeons have begun to use robot-assisted radical prostatectomy more frequently. We aimed to determine the clinical benefits and harms of the robotic surgical system for radical prostatectomy (robot-assisted radical prostatectomy) compared with the open and laparoscopic surgical methods. We also assessed the cost-effectiveness of robot-assisted versus open radical prostatectomy in patients with clinically localized prostate cancer in Ontario. Methods We performed a literature search and included prospective comparative studies that examined robot-assisted versus open or laparoscopic radical prostatectomy for prostate cancer. The outcomes of interest were perioperative, functional, and oncological. The quality of the body of evidence was examined according to the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Working Group criteria. We also conducted a cost–utility analysis with a 1-year time horizon. The potential long-term benefits of robot-assisted radical prostatectomy for functional and oncological outcomes were also evaluated in a 10-year Markov model in scenario analyses. In addition, we conducted a budget impact analysis to estimate the additional costs to the provincial budget if the adoption of robot-assisted radical prostatectomy were to increase in the next 5 years. A needs assessment determined that the published literature on patient perspectives was relatively well developed, and that direct patient engagement would add relatively little new information. Results Compared with the open approach, we found robot-assisted radical prostatectomy reduced length of stay and blood loss (moderate quality evidence) but had no difference or inconclusive results for functional and oncological outcomes

The multicenter, randomized, double-blind, double-dummy, placebo-controlled REACTT trial suggested that treatment with tadalafil once daily (OaD) started early after bilateral nerve-sparing radical prostatectomy (nsRP) for prostate cancer may contribute to erectile function (EF)-recovery, which was predefined as achieving an International Index of Erectile Function (IIEF)-EF score ≥22. Here, we report descriptive post-hoc analyses, using the more strict definition for EF-recovery of returning back to the pre-surgery IIEF-EF-level ("back-to-baseline analysis"). REACTT included 422 men <68 years with adenocarcinoma of the prostate and preoperative IIEF-EF ≥22 who underwent nsRP at 50 centers from 9 European countries and Canada. Patients were randomized post-nsRP 1:1:1 to 9-month double-blind treatment (DBT) with tadalafil 5 mg OaD (n = 139), tadalafil 20 mg on-demand (pro-re-nata, PRN; n = 142), or placebo (n = 141), followed by 6-week drug-free washout (DFW) and 3-month open-label tadalafil OaD treatment (OLT). Proportion of patients returning to their preoperative IIEF-EF category (22-25 or ≥26) at the end of DBT, DFW, and OLT. Overall, 92.4% of patients had pre-surgery (baseline) IIEF-EF scores ≥26 (tadalafil OaD 94.2%, PRN 91.6%, placebo 91.5%), 7.4% had IIEF-EF 22-25. At the end of DBT, 22.3% of patients on tadalafil OaD had achieved "back-to-baseline" IIEF-EF, compared with 11.3% on tadalafil PRN and 7.8% on placebo. Of all 58 patients "back-to-baseline" at the end of DBT, only 1 PRN-group patient had started from a baseline IIEF-EF <26. The treatment-group difference at the end of DBT was not maintained after DFW. After 3 months of OLT with tadalafil OaD, the proportion of patients with "back-to-baseline" IIEF-EF had almost doubled in all 3 groups. Changing the definition for EF-recovery from IIEF-EF ≥22 to the more strict definition of "returning back-to-baseline IIEF-EF" had no major impact. Tadalafil OaD started early after nsRP improved

Laparoscopic cholecystectomy has evolved from being a reluctantly accepted novelty to the most widely adopted procedure. It reached a high popularity even before randomized trials could be carried out. Open cholecystectomy was at one time considered the ''gold standard'', only to be replaced by laparoscopic cholecystectomy. Today the same is happening with radical prostatectomy. Open radical prostatectomy (ORP) was the reference standard. Afterwards, came laparoscopic radical prostatectomy (LRP), which matched ORP in terms of the trifecta of oncological, continence and sexual function outcomes. Robot-assisted radical prostatectomy (RARP) was the next step in the evolution. Since 2000, it has become very widespread because of private practice promotion among surgeons and marketing hype by the manufacturers. Furthermore, patients ask for this operation. In the last eight years, there has been a rise in conceptual changes, especially in operative techniques, to improve outcomes following RARP. This review will focus on some of the key concepts emerged in the field of robotic surgery, to improve outcomes following RARP. The lack of randomized controlled trials makes it difficult to make true comparisons with ORP, LRP and other methods of treating localized prostate cancer.

To identify the health-related quality of life (HRQoL) domains that radical prostatectomy (RP) impacts most negatively and to define the recovery of these domains over 30 months of observation. A total of 1,200 RP patients completed the Patient-Oriented Prostate Utility Scale-Psychometric (PORPUS-P; range 0-100, higher is better), a prostate cancer-specific HRQoL measure, prior to RP and at 0-3 (T1), 3-9 (T2), 9-18 (T3) and 18-30 (T4) months post-RP. HRQoL changes were examined using paired t tests and a mixed-effect growth curve model. Multivariable analyses were performed to investigate demographic and treatment factors predicting the change in HRQoL. Mean baseline PORPUS-P score, 83.1, fell to 66.5 (p < 0.001) at T1. Over time HRQoL improved but did not return to baseline (T4 mean 76.4, p < 0.001). Domain analysis revealed that sexual function (p < 0.001), sexual drive (p < 0.001), energy (p = 0.001) and bladder control (p < 0.001) failed to return to baseline at T4. Sexual function demonstrated the greatest impairment overall. The multivariable model revealed Black men experienced greater losses in global HRQoL compared with White men (coefficient -2.77, 95% CI -5.00 to -0.54, p = 0.015). High baseline HRQoL, pro-erectile aid use and bilateral nerve-sparing were significantly associated with smaller reductions in HRQoL post-RP. Overall HRQoL, sexual drive, sexual function, energy and bladder control do not return to preoperative levels within 30 months post-RP. Black patients experience the greatest reductions in HRQoL. HRQoL losses may be ameliorated by use of pro-erectile aids. These findings help to identify at-risk patient populations and inform survivorship programs.

Background and Objectives: Our objective is to clarify the effect of previous transurethral resection of the prostate (TURP) or open prostatectomy (OP) on surgical, oncological, and functional outcomes after robot-assisted radical prostatectomy (RARP). Methods: Between August 1, 2009, and March 31, 2013, 380 patients underwent RARP. Of these, 25 patients had undergone surgery for primary bladder outlet obstruction (TURP, 20 patients; OP, 5 patents) (group 1). A match-paired analysis was performed to identify 36 patients without a history of prostate surgery with equivalent clinicopathologic characteristics to serve as a control group (group 2). Patients followed up for 12 months were assessed. Results: Both groups were similar with respect to preoperative characteristics, as mean age, body mass index, median prostate-specific antigen, prostate volume, clinical stage, the biopsy Gleason score, D'Amico risk, the American Society of Anesthesiologists (ASA) classification score, the International Prostate Symptom Score, continence, and potency status. RARP resulted in longer console and anastomotic time, as well as higher blood loss compared with surgery-naive patients. We noted a greater rate of urinary leakage (pelvic drainage, >4 d) in group 1 (12% vs 2,8%). The anastomotic stricture rate was significantly higher in group 1 (16% vs 2.8%). No difference was found in the pathologic stage, positive surgical margin, and nerve-sparing procedure between the groups. Biochemical recurrence was observed in 12% (group 1) and 11.1% (group 2) of patients, respectively. No significant difference was found in the continence and potency rates. Conclusions: RARP after TURP or OP is a challenging but oncologically promising procedure with a longer console and anastomosis time, as well as higher blood loss and higher anastomotic stricture rate.

Urinary incontinence remains a major concern for patients undergoing radical prostatectomy. Its prevalence can reach 20% in the late postoperative period. This clinical study investigated the differences of a dynamic evaluation of the urethra and pelvic floor contraction using perineal ultrasound in men without prostate surgery and in men submitted to radical prostatectomy with and without stress urinary incontinence. Ninety two male patients were included, which 70% of them underwent radical prostatectomy (RP) for more than one year. Thirty one men with clinically post prostatectomy incontinence were compared by two-dimensional (2D) perineal ultrasound to 34 patients without post prostatectomy incontinence and to 27 men without surgery in two centers in Brazil. Our results showed that the continent group presented the urethral angle at rest significantly lower than the prostate group (p = 0.0002). We also observed that the incontinent group showed the displacement of the anterior bladder neck during contraction significantly lower than the continent group (p = 0.008). We found that the continent group presented the urethral angle at rest significantly lower than the prostate group. The incontinent group also showed the anterior bladder neck displacement during contraction significantly lower than the continent group. It was more evident when the severe incontinent group and the continent group were compared.

To review the various methods of outcomes assessment used for effectiveness studies comparing retropubic radical prostatectomy (RRP), laparoscopic radical prostatectomy (LRP), and robotic-assisted laparoscopic prostatectomy (RALP). A review of the peer reviewed literature was performed for reported series of RRP, LRP, and RALP using Pubmed and MEDLINE with emphasis on comparing perioperative, functional, and oncologic outcomes. Common methods used for outcomes assessment were categorized and compared, highlighting the pros and cons of each approach. The majority of the literature comparing RRP, LRP, and RALP comes in the form of observational data or administrative data from secondary datasets. While randomized controlled trials are ideal for outcomes assessment, only one such study was identified and was limited. Non-randomized observational studies contribute to the majority of data, however are limited due to retrospective study design, lack of consistent endpoints, and limited application to the general community. Administrative data provide accurate assessment of operative outcomes in both academic and community settings, however has limited ability to convey accurate functional outcomes. Non-randomized observational studies and secondary data are useful resources for assessment of outcomes; however, limitations exist for both. Neither is without flaws, and conclusions drawn from either should be viewed with caution. Until standardized prospective comparative analyses of RRP, LRP, and RALP are established, comparative outcomes data will remain imperfect. Urologic researchers must strive to provide the best available outcomes data through accurate prospective data collection and consistent outcomes reporting.

The Cancer of the Prostate Risk Assessment Post-Surgical (CAPRA-S) score is a simple post-operative risk assessment tool predicting disease recurrence after radical prostatectomy, which is easily calculated using available clinical data. To be widely useful, risk tools require multiple external validations. We aimed to validate the CAPRA-S score in an Australian multi-institutional population, including private and public settings and reflecting community practice. The study population were all men on the South Australian Prostate Cancer Clinical Outcomes Collaborative Database with localized prostate cancer diagnosed during 1998-2013, who underwent radical prostatectomy without adjuvant therapy (n = 1664). Predictive performance was assessed via Kaplan-Meier and Cox proportional regression analyses, Harrell's Concordance index, calibration plots and decision curve analysis. Biochemical recurrence occurred in 342 (21%) cases. Five-year recurrence-free probabilities for CAPRA-S scores indicating low (0-2), intermediate (3-5) and high risk were 95, 79 and 46%, respectively. The hazard ratio for CAPRA-S score increments was 1.56 (95% confidence interval 1.49-1.64). The Concordance index for 5-year recurrence-free survival was 0.77. The calibration plot showed good correlation between predicted and observed recurrence-free survival across scores. Limitations include the retrospective nature and small numbers with higher CAPRA-S scores. The CAPRA-S score is an accurate predictor of recurrence after radical prostatectomy in our cohort, supporting its utility in the Australian setting. This simple tool can assist in post-surgical selection of patients who would benefit from adjuvant therapy while avoiding morbidity among those less likely to benefit. © 2017 Royal Australasian College of Surgeons.

Radical prostatectomy (RP) is the most common definitive invasive treatment option for localized prostate cancer. Although the different surgical procedures-open RP, laparoscopic RP, and robot-assisted laparoscopic RP-do not differ significantly for the results of postoperative erectile dysfunction (ED) and continence, the fear of losing erectile function (EF) is often an important factor for preoperatively sexually active men when deciding for or against a procedure. To review the available literature on rehabilitation of EF after RP and to evaluate the value of the "Kiel concept" against different strategies of phosphodiesterase type 5 inhibitor (PDE5i) low-dose treatments. A review of the available literature up to January 2017 was undertaken using the key terms postsurgical ED, penile rehabilitation," PDE5i rehabilitation, and PDE5i daily dose treatment. As a main outcome measure we chose reviewed different concepts on the rehabilitation of EF after RP, taking into account the clinical background of the Kiel concept. The different therapeutic concepts for rehabilitation of EF after nerve-sparing RP are surprising. The most frequently applied method is application of different PDE5is. Despite different studies on efficacy, the issue of an optimal concept remains unresolved. The reason for this, among others, can be found in the difficulty of comparing different studies, which can vary with respect to the degree of nerve sparing, postoperative preservation of nocturnal erections, concomitant morbidity, and the number and experience of surgeons. In 86% of patients, the Kiel concept has been shown to support rehabilitation of EF after nerve-sparing RP with some form of therapeutic method. The Kiel concept is one therapeutic option among other comparable therapeutic options. Osmonov DK, Jünemann KP, Bannowsky A.

Purpose We describe current trends in robotic and open radical prostatectomy in the United States after examining case logs for American Board of Urology certification. Materials and Methods American urologists submit case logs for initial board certification and recertification. We analyzed logs from 2004 to 2010 for trends and used logistic regression to assess the impact of urologist age on robotic radical prostatectomy use. Results A total of 4,709 urologists submitted case logs for certification between 2004 and 2010. Of these logs 3,374 included 1 or more radical prostatectomy cases. Of the urologists 2,413 (72%) reported performing open radical prostatectomy only while 961 (28%) reported 1 or more robotic radical prostatectomies and 308 (9%) reported robotic radical prostatectomy only. During this 7-year period we observed a large increase in the number of urologists who performed robotic radical prostatectomy and a smaller corresponding decrease in those who performed open radical prostatectomy. Only 8% of patients were treated with robotic radical prostatectomy by urologists who were certified in 2004 while 67% underwent that procedure in 2010. Median age of urologists who exclusively performed open radical prostatectomy was 43 years (IQR 38–51) vs 41 (IQR 35–46) for those who performed only robotic radical prostatectomy. Conclusions While the rate was not as high as the greater than 85% industry estimate, 67% of radical prostatectomies were done robotically among urologists who underwent board certification or recertification in 2010. Total radical prostatectomy volume almost doubled during the study period. These data provide nonindustry based estimates of current radical prostatectomy practice patterns and further our understanding of the evolving surgical treatment of prostate cancer. PMID:22498227

Step-by-step explanation of the technique using videos and pictures (educational video) to demonstrate the anatomy of the intrapelvic bundles of the autonomic nerve system innervating the bladder, rectum, and pelvic floor. Tertiary referral center. One 37-year-old woman with an infiltrative endometriotic nodule on the anterior third of the left uterosacral ligament and one 34-year-old woman with rectovaginal endometriosis. Exposure and preservation by direct visualization of the hypogastric nerve and the inferior hypogastric plexus. Visual control and identification of the autonomic nerve branches of the posterior pelvis. Exposure and preservation of the hypogastric nerve and the superficial part of the left hypogastric nerve were achieved on the first patient. Nerve roots S2, S3, and S4 were identified on the second patient, allowing for the exposure and preservation of the pelvic splanchnic nerves and the deep portion inferior hypogastric plexus. Radical surgery for endometriosis can induce urinary dysfunction in 2.4%-17.5% of patients owing to lesion of the autonomic nerves. The surgeon's knowledge of the anatomy of these nerves is the main factor for preserving postoperative urinary function. The following nerves are the intrapelvic part of the autonomic nervous system: the hypogastric nerves, which derive from the superior hypogastric plexus and carry the sympathetic signals to the internal urethral and anal sphincters as well as to the pelvic visceral proprioception; and the pelvic splanchnic nerves, which arise from S2 to S4 and carry nociceptive and parasympathetic signals to the bladder, rectum, and the sigmoid and left colons. The hypogastric and pelvic splanchnic nerves merge into the pararectal fossae to form the inferior hypogastric plexus. Most

Whereas open radical prostatectomy is performed extraperitoneally, minimally invasive radical prostatectomy is typically performed within the peritoneal cavity. Our objective was to determine whether minimally invasive radical prostatectomy is associated with an increased risk of small bowel obstruction compared with open radical prostatectomy. In the U.S. Surveillance, Epidemiology and End Results (SEER)-Medicare database, we identified 14,147 men found to have prostate cancer from 2000 to 2008 treated by open (n = 10,954) or minimally invasive (n = 3193) radical prostatectomy. Multivariable Cox proportional hazard models were used to examine the impact of surgical approach on the diagnosis of small bowel obstruction, as well as the need for lysis of adhesions and exploratory laparotomy. During a median follow-up of 45 and 76 months, respectively, the cumulative incidence of small bowel obstruction was 3.7% for minimally invasive and 5.3% for open radical prostatectomy (p = 0.0005). Lysis of adhesions occurred in 1.1% of minimally invasive and 2.0% of open prostatectomy patients (p = 0.0003). On multivariable analysis, there was no significant difference between minimally invasive and open prostatectomy with respect to small bowel obstruction (HR 1.17, 95% CI 0.90, 1.52, p = 0.25) or lysis of adhesions (HR 0.87, 95% CI 0.50, 1.40, p = 0.57). Limitations of the study include the retrospective design and use of administrative claims data. Relative to open radical prostatectomy, minimally invasive radical prostatectomy is not associated with an increased risk of postoperative small bowel obstruction and lysis of adhesions.

To measure the effect of treatment choice (pelvic irradiation [XRT] versus radical prostatectomy [RP] with or without nerve sparing) on sexual function and sexual bother during the first 2 years after treatment. We studied sexual function and sexual bother in 438 men recently diagnosed with early-stage prostate cancer and treated with XRT or RP with or without nerve sparing. Outcomes were assessed with the University of California, Los Angeles Prostate Cancer Index, a validated health-related quality-of-life instrument that includes these two domains. To minimize the influence of other factors, we adjusted for age, comorbidity, general health, and previous treatment for erectile dysfunction. All subjects were drawn from CaPSURE, a national, longitudinal data base. Sexual function improved over time during the first year in all treatment groups; however, during the second year, sexual function began to decline in the XRT group. Older patients who received XRT showed substantial declines in sexual function throughout the 2 years, and older patients who underwent RP experienced a return of very low baseline sexual function. Sexual function was improved by the use of nerve-sparing procedures or erectile aids. Alterations in sexual bother were ameliorated by many factors, including age, general health perceptions, and sexual function. Patients undergoing XRT or RP with or without nerve sparing all showed comparable rates of improvement in sexual function during the first year after treatment for early-stage prostate cancer. However, in the second year after treatment, patients treated with XRT began to show declining sexual function; patients treated with RP did not.

Purpose ICI has low utilization and high discontinuation rates. We examined factors associated with ICI use, long-term satisfaction with ICI, and reasons for discontinuation in men having undergone radical prostatectomy. Materials and Methods Between October 2000 and September 2003, 731 men undergoing open radical retropubic prostatectomy were enrolled in a prospective outcomes study. The eight-year follow-up evaluation included the UCLA-PCI and a survey capturing ICI use, satisfaction, and reasons for discontinuation. Logistic regression was utilized to determine associations between ICI use and pre-operative variables. Results Eight-year self-assessment was completed by 368 (50.4%) men; 140 (38%) of these indicated prior or current ICI use, with only 34 using ICI at eight years. Forty four percent of men were satisfied with ICI. Discontinuation reasons included: dislike (47%), pain (33%), return of erection (19%), inefficacy (14%), and no partner (6%). Men trying ICI had greater pre-operative UCLA-PCI sexual function scores (75.2 vs. 65.62, p = 0.00005) and greater declines in this score at three months (p = 0.0002) and two years (p = 0.003). Higher pre-operative sexual function scores were independently associated with utilization of ICI in a model adjusted for age, marital status, nerve sparing status, and BMI (OR =1.021, 95% CI 1.008–1.035). Conclusions Men pursuing ICI have better baseline erectile function and experience greater deterioration in erectile function during the early post-operative period. Despite high efficacy, many discontinue ICI due to dislike or discomfort. Satisfaction rates with ICI indicate its long-term role in restoring sexual function in men with PPED. PMID:23174252

The effectiveness of cancer control is unclear after radical prostatectomy for patients with clinical T3 prostate cancer. We retrospectively reviewed 1409 patients who underwent radical prostatectomy between April 2007 and December 2014, including 210 patients with cT3 prostate cancer. Nine patients who received neoadjuvant hormonal therapy and three patients who were lost to follow-up were excluded from the analysis. Clinical staging was performed by an experienced radiologist using preoperative magnetic resonance imaging findings. We analyzed the predictors of biochemical recurrence using Cox proportional hazard analyses. A total of 113 patients (57%) underwent radical retropubic prostatectomy and 85 patients (43%) underwent robot-assisted radical prostatectomy. The median follow-up period was 36 months. Downstaging occurred for 60 patients (30%), positive surgical margins were identified in 117 patients (59%), and biochemical recurrence was observed for 89 patients (45%). In the multivariate analyses, the independent preoperative predictors of biochemical recurrence were ≥50% proportion of positive biopsy cores [hazard ratio (HR): 2.858, P < 0.0001] and a biopsy Gleason score of ≥8 (HR: 1.800, P = 0.0093). The independent post-operative predictors of biochemical recurrence were positive surgical margins (HR: 2.490, P = 0.0018) and seminal vesicle invasion (HR: 2.750, P < 0.0001). Among patients with cT3 prostate cancer, the percentage of positive biopsy cores and the biopsy Gleason score should be considered to select treatment. Compared with radical retropubic prostatectomy, robot-assisted radical prostatectomy may be a feasible treatment option in this setting.

Nerve-sparing radical hysterectomy (NSRH) was introduced with the aim to reduce pelvic dysfunctions related to conventional radical hysterectomy (RH). Here, we sought to assess the effectiveness and safety of NSRH in a relatively large number of the patients of cervical cancer (CC) patients undergoing either primary surgery or neoadjuvant chemotherapy (NACT) followed by surgery. Outcomes of consecutive patients undergoing NSRH and of a historical cohort of patients undergoing conventional RH were retrospectively reviewed. This study included 325 (49.8%) and 327 (50.2%) undergoing NSRH and RH, respectively. Via a multivariable model, nodal status was the only factor predicting for DFS (hazard ratio [HR]=2.09; 95% confidence interval [CI]=1.17-3.73; p=0.01). A trend towards high risk of recurrence was observed for patients affected by locally advanced cervical cancer (LACC) undergoing NACT followed by surgery (HR=2.57; 95% CI=0.95-6.96; p=0.06). Type of surgical procedures (NSRH vs. RH) did not influence risk of recurrence (p=0.47). Similarly, we observed that the execution of NSRH rather than RH had not a detrimental effect on OS (HR=1.19; 95% CI=0.16-9.01; p=0.87). Via multivariable model, no factor directly correlated with OS. No difference in early complication rates was observed between the study groups. Conversely, a significant higher number of late complications was reported in RH versus NSRH groups (p=0.02). Our data suggested that NSRH upholds effectiveness of conventional RH, without increasing recurrence and complication rates but improving pelvic dysfunction rates. Copyright © 2018.

Post-radical prostatectomy erectile dysfunction (post RP ED) is a major postoperative complication with a great impact on the quality of life of the patients. Until present, no proper algorithm or guideline based on the clinical trials has been established for the management of post RP ED. According to literature, it is better to initiate a penile rehabilitation program as soon as possible after surgery than doing nothing, in order to prevent and limit the postoperative local hypoxygenation and fibrosis. The results of numerous clinical trials regarding the effectiveness of the phosphodiesterase 5 inhibitors therapy on post RP ED have made them the gold standard treatment. Encouraging results have been achieved in studies with vacuum erectile devices, intraurethral suppositories with alprostadil and intracavernosal injections, but due to their side effects, especially in the cases of intracavernosal injections and intraurethral suppositories, their clinical use was limited therefore making them a second line option for the post RP ED treatment. What should not be forgotten is that penile implant prosthesis has proven very effective, numerous studies confirming high rates of satisfaction for both patients and partners. PMID:28255370

A comparison of the robotic-assisted versus retropubic radical prostatectomy.

Laviana, A A; Hu, J C

After Walsh's detailed anatomic description of pelvic anatomy in 1979, the retropubic radical prostatectomy (RRP) was the predominant surgical treatment for prostate cancer for more than twenty-five years. Over the past decade, however, the robotic-assisted radical prostatectomy (RARP) has grown increasingly popular and now is the most used surgical modality. Willingness to adopt this approach has been confounded by the novelty of technology and widespread marketing campaigns. In this article, we performed a literature search comparing radical retropubic prostatectomy to robotic-assisted radical prostetectomy with regard to perioperative, oncologic, and quality-of-life outcomes. We performed a PubMed literature search for a review of articles published between 2000 and 2013. Relevant articles were highlighted using the following keywords: robot or robotic prostatectomy, open or retropubic prostatectomy. Perioperative outcomes including decreased blood loss, fewer blood transfusions, and decreased length of hospital stay tend to favor RARP, while perioperative mortality is near negligible in both. Short-term positive surgical margins, prostate-specific antigen recurrence free survival, and need for salvage therapy following RARP are similar to RRP, though data at greater than ten years is limited. Preservation of urinary and sexual function and quality of life favored RARP, though this is dependent on surgeon technique. Finally, cost, though evolving, favors RRP. In our current state, most prostatectomies will continue to be perfromed robotically. Though there is evidence the robotic-assisted radical prostatectomy offers shorter lengths of stay, decreased intraoperative blood loss, faster return of sexual function and continence, there is a paucity on long-term oncologic outcomes. Rigorous, prospective randomized-controlled trials need to be performed to determine the long-term success of the robotic-assisted radical prostatectomy and whether it is cost

Introduction: We assess the practice patterns of artificial urinary sphincter (AUS) and urethral sling insertion after radical prostatectomy (RP) from a large population-based cohort. Methods: We examined 25 346 men in Ontario, Canada who underwent RP between 1993 and 2006. Using hospital and cancer registry data, we identified patients who subsequently underwent an incontinence procedure. We characterized the practice patterns of post-prostatectomy incontinence procedures across Ontario during the study interval. Results: A total of 703 (2.8%) men underwent subsequent insertion of an AUS and 282 (1.1%) underwent a urethral sling procedure (985 total incontinence procedures, 3.9%) over the study period. During the study period, 121 hospitals performed RP. Among them, 32 (26%) hospitals performed both RP and AUS/sling procedures, and 89 (74%) performed RP only. Four hospitals performed AUS/sling procedures but not RP. Of the 36 institutions that performed AUS/sling procedures, the median annual case volume was 0.29 (interquartile range: 0.083-0.75). Of all incontinence procedures, 56% were performed at 3 academic institutions. When examining observed rates of AUS/sling procedures compared with expected rates from the overall cohort, 15 of 32 hospitals (47%) performed significantly fewer incontinence procedures than expected given their RP case volume (p range: <0.0001–0.0390) and 5 (16%) performed significantly more (p range: <0.0001–0.038). Conclusions: A small number of academic institutions provide most of the surgical care for men with incontinence following RP in Ontario. Many centres that perform RP refer out to other centres to surgically manage their patients’ incontinence. PMID:25408805

The peripheral nervous system plays an important role in motility, sensory, and autonomic functions of the human body. Preservation of peripheral nerves in surgery, namely nerve-sparing surgery, is now promising technique to avoid functional deficits of the limbs and organs following surgery as an aspect of the improvement of quality of life of patients. Detection of peripheral nerves including myelinated and unmyelinated nerves is required for the nerve-sparing surgery; however, conventional nerve identification scheme is sometimes difficult to identify peripheral nerves due to similarity of shape and color to non-nerve tissues or its limited application to only motor peripheral nerves. To overcome these issues, we proposed a label-free detection technique of peripheral nerves by means of Raman spectroscopy. We found several fingerprints of peripheral myelinated and unmyelinated nerves by employing a modified principal component analysis of typical spectra including myelinated nerve, unmyelinated nerve, and adjacent tissues. We finally realized the sensitivity of 94.2% and the selectivity of 92.0% for peripheral nerves including myelinated and unmyelinated nerves against adjacent tissues. Although further development of an intraoperative Raman spectroscopy system is required for clinical use, our proposed approach will serve as a unique and powerful tool for peripheral nerve detection for nerve-sparing surgery in the future.

To report our unique approach for individualizing robotic prostate cancer surgery by risk stratification and sub classification of the periprostatic space into 4 distinct compartments, and thus performing 4 precise different grades of nerve sparing based on neurosurgical principles and to present updated potency and continence outcomes data of patients undergoing robotic-assisted laparoscopic prostatectomy (RALP) using our risk-stratified approach based on layers of periprostatic fascial dissection. (1) Between January 2005 and December 2010, 2,536 men underwent RALP by a single surgeon at our institution. (2) Included patients were those with ≥ 1-year follow-up and were preoperatively continent and potent, defined as having a SHIM questionnaire score of >21; thus, the final number of patient in the study cohort was 1,335. (3) Postoperative potency was defined as the ability to have successful intercourse (score of ≥ 4 on question 2 of the SHIM); continence was defined as the use of no pads per 24 h. (1) The potency and continence for NS grades 1, 2, 3, and 4 were found to be 90.6, 76.2, 60.5, and 57.1 % (P < 0.001) and 98, 93.2, 90.1, and 88.9 % (P < 0.001), respectively. (2) The overall PSM rates for patients with NS grades 1, 2, 3, and 4 were 10.5, 7, 5.8, and 4.8 %, respectively (P = 0.064). The study found a correlation between risk-stratified grades of NS technique and continence and potency. Patients with lesser grades of NS had higher rates of potency and continence.

To investigate the early and delayed effects of cavernous nerve electrocautery injury (CNEI) in a rat model, with the expectation that this model could be used to test rehabilitation therapies for erectile dysfunction (ED) after radical prostatectomy (RP). In all, 30 male Sprague-Dawley rats were randomly divided equally into two groups (15 per group). The control group received CNs exposure surgery only and the experimental group received bilateral CNEI. At 1, 4 and 16 weeks after surgery (five rats at each time point), the ratio of maximal intracavernosal pressure (ICP) to mean arterial pressure (MAP) was measured in the two groups. Neurofilament expression in the dorsal penile nerves was assessed by immunofluorescent staining and Masson's trichrome staining was used to assess the smooth muscle to collagen ratio in both groups. At the 1-week follow-up, the mean ICP/MAP was significantly lower in the CNEI group compared with the control group, at 9.94% vs 70.06% (P < 0.05). The mean ICP/MAP in the CNEI group was substantially increased at the 4- (35.97%) and 16-week (37.11%) follow-ups compared with the 1-week follow-up (P < 0.05). At all three follow-up time points, the CNEI group had significantly decreased neurofilament staining compared with the control group (P < 0.05). Also, neurofilament expressions in the CNEI group at both 4 and 16 weeks were significantly higher than that at 1 week (P < 0.05), but there was no difference between 4 and 16 weeks (P > 0.05). The smooth muscle to collagen ratio in the CNEI group was significantly lower than in the control group at the 4- and 16-week follow-ups (P < 0.05), and the ratio at 16 weeks was further reduced compared with that at 4 weeks (P < 0.05). In the CNEI rat model, we found the damaging effects of CNEI were accompanied by a decline in ICP, reduced numbers of nerve fibres in the dorsal penile nerve, and exacerbated fibrosis in the corpus cavernosum. This may provide a basis for studying potential preventative

The current status of robot-assisted radical prostatectomy

Robot-assisted radical prostatectomy (RARP) is a rapidly evolving technique for the treatment of localized prostate cancer. In the United States, over 65% of radical prostatectomies are robot-assisted, although the acceptance of this technology in Europe and the rest of the world has been somewhat slower. This article reviews the current literature on RARP with regard to oncological, continence and potency outcomes–the so-called 'trifecta'. Preliminary data appear to show an advantage of RARP over open prostatectomy, with reduced blood loss, decreased pain, early mobilization, shorter hospital stay and lower margin rates. Most studies show good postoperative continence and potency with RARP; however, this needs to be viewed in the context of the paucity of randomized data available in the literature. There is no definitive evidence to show an advantage over standard laparoscopy, but the fact that this technique has reached parity with laparoscopy within 5 years is encouraging. Finally, evolving techniques of single-port robotic prostatectomy, laser-guided robotics, catheter-free prostatectomy and image-guided robotics are discussed. PMID:19050687

To assess the effect of a multicomponent theory-based intervention, incorporating patient information guides, an evidence summary, audit and feedback processes and a provider directory, in the provision/receipt of preoperative pelvic floor muscle training (PFMT) among patients undergoing radical prostatectomy. Over an 18-month period (9 months before and 9 months after the intervention), we measured the provision/receipt of preoperative PFMT using surveys of patients undergoing radical prostatectomy at one public hospital (n = 32) and two private hospitals (n = 107) in Western Sydney, Australia, as well as practice audits of associated public sector (n = 4) and private sector (n = 2) providers of PFMT. Self-report urinary incontinence was assessed 3 months after radical prostatectomy using the International Consultation on Incontinence Questionnaire - Urinary Incontinence Form (ICIQ-UI Short Form). There was a significant increase in the proportion of survey respondents receiving preoperative PFMT post-intervention (post-intervention: 42/58 respondents, 72% vs pre-intervention: 37/81 respondents, 46%, P = 0.002). There was a corresponding significant increase in provision of preoperative PFMT by private sector providers (mean [sd] post-intervention: 16.7 [3.7] patients/month vs pre-intervention: 12.1 [3.6] patients/month, P = 0.018). Respondents receiving preoperative PFMT had significantly better self-report urinary incontinence at 3 months after radical prostatectomy than those who did not receive preoperative PFMT (mean [sd] ICIQ-UI Short Form sum-scores: 6.2 [5.0] vs 9.2 [5.8], P = 0.002). The intervention increased the provision/receipt of preoperative PFMT among patients undergoing radical prostatectomy. Additional component strategies aimed at increasing the use of public sector providers may be necessary to further improve PFMT receipt among patients undergoing radical prostatectomy in the public hospital system. © 2013 The Authors.

Does penile rehabilitation have a role in the treatment of erectile dysfunction following radical prostatectomy?

PubMed

Blecher, Gideon; Almekaty, Khaled; Kalejaiye, Odunayo; Minhas, Suks

2017-01-01

In men undergoing radical treatment for prostate cancer, erectile function is one of the most important health-related quality-of-life outcomes influencing patient choice in treatment. Penile rehabilitation has emerged as a therapeutic measure to prevent erectile dysfunction and expedite return of erectile function after radical prostatectomy. Penile rehabilitation involves a program designed to increase the likelihood of return to baseline-level erectile function, as opposed to treatment, which implies the therapeutic treatment of symptoms, a key component of post-radical prostatectomy management. Several pathological theories form the basis for rehabilitation, and a plethora of treatments are currently in widespread use. However, whilst there is some evidence supporting the concept of penile rehabilitation from animal studies, randomised controlled trials are contradictory in outcomes. Similarly, urological guidelines are conflicted in terms of recommendations. Furthermore, it is clear that in spite of the lack of evidence for the role of penile rehabilitation, many urologists continue to employ some form of rehabilitation in their patients after radical prostatectomy. This is a significant burden to health resources in public-funded health economies, and no effective cost-benefit analysis has been undertaken to support this practice. Thus, further research is warranted to provide both scientific and clinical evidence for this contemporary practice and the development of preventative strategies in treating erectile dysfunction after radical prostatectomy.

Most patients benefitted from immediate facial nerve grafting after radical parotidectomy. Even weak movement is valuable and can be augmented with secondary static operations. Post-operative radiotherapy does not seem to affect the final outcome of facial function. During radical parotidectomy, the sacrifice of the facial nerve results in severe disfigurement of the face. Data on the principles and outcome of facial nerve reconstruction and reanimation after radical parotidectomy are limited and no consensus exists on the best practice. This study retrospectively reviewed all patients having undergone radical parotidectomy and immediate facial nerve reconstruction with a free, non-vascularized nerve graft at the Helsinki University Hospital, Helsinki, Finland during the years 1990-2010. There were 31 patients (18 male; mean age = 54.7 years; range = 30-82) and 23 of them had a sufficient follow-up time. Facial nerve function recovery was seen in 18 (78%) of the 23 patients with a minimum of 2-year follow-up and adequate reporting available. Only slight facial movement was observed in five (22%), moderate or good movement in nine (39%), and excellent movement in four (17%) patients. Twenty-two (74%) patients received post-operative radiotherapy and 16 (70%) of them had some recovery of facial nerve function. Nineteen (61%) patients needed secondary static reanimation of the face.

Open conversion during minimally invasive radical prostatectomy: impact on perioperative complications and predictors from national data.

Despite the increased use of minimally invasive radical prostatectomy, open conversion may occur due to surgical complications, surgeon inexperience or failure to progress. We used nationally representative data to quantify the impact of open conversion compared to nonconverted minimally invasive radical prostatectomy and open radical prostatectomy, and identify predictors of open conversion. Years 2004 to 2010 of the Nationwide Inpatient Sample were queried for patients who underwent radical prostatectomy to analyze the association of open conversion during minimally invasive radical prostatectomy with Clavien complications. Multivariate regression models yielded significant predictors of open conversion. From 2004 to 2010, 134,398 (95% CI 111,509-157,287) minimally invasive radical prostatectomies were performed with a 1.8% (95% CI 1.4-2.1) open conversion rate, translating to 2,360 (95% CI 2,001-2,720) conversions. Open conversion cases had a longer length of stay (4.17 vs 1.71 days, p <0.001) and higher hospital charges ($51,049 vs $37,418, p <0.001) than nonconverted cases. Of open conversion cases 45.2% experienced a complication vs 7.2% and 12.9% of minimally invasive radical prostatectomy and open radical prostatectomy cases, respectively (p <0.001). After adjusting for age and comorbidities, open conversion was associated with significantly increased odds of a Clavien grade 1, 2, 3 and 4 complication compared to nonconverted minimally invasive radical prostatectomy and open radical prostatectomy (OR range 2.913 to 15.670, p <0.001). Significant multivariate predictors of open conversion were obesity (OR 1.916), adhesions (OR 3.060), anemia (OR 5.692) and surgeon volume for minimally invasive radical prostatectomy less than 25 cases per year (OR 7.376) (all p <0.01). Open conversion during minimally invasive radical prostatectomy is associated with a higher than expected increase in complications compared to open radical prostatectomy and minimally

Twenty-five to thirty percent of patients with prostate cancer present with locally advanced disease. While risk stratification remains the same with high incidence of upstaging of disease on imaging and histopathological evaluation; there have been progressive refinements in surgical therapy. With availability of reasonably robust data, radical prostatectomy in men with locally advanced prostate cancers seems to effect improvement in both cancer specific and overall survival rates in comparison to the current standard of care of radiation with androgen deprivation therapy. Studies using radical prostatectomy as a part of multimodality approach have also shown promising results. There is an imminent need for well-designed prospective studies of benefits of radical prostatectomy over radiation and androgen deprivation as well as benefits of multimodality therapy over monotherapy. Surgery for patients with locally advanced prostate cancer is technically challenging. Surgical outcomes are comparable to those of organ-confined disease when performed in high-volume centers. Neoadjuvant therapies prior to radical prostatectomy might improve surgical outcomes, but whether they will translate into a better cancer specific and overall survival are yet to be ascertained.

Relationships between perioperative physical activity and urinary incontinence after radical prostatectomy: an observational study

Background Higher physical activity levels are continence-protective in non-prostate cancer populations. Primary aims of this study were to investigate changes in physical activity levels over the perioperative period in patients having radical prostatectomy, and relationships between perioperative physical activity levels and post-prostatectomy urinary incontinence. Methods A prospective analysis of patients having radical prostatectomy and receiving perioperative physiotherapy including pelvic floor muscle training and physical activity prescription (n = 33). Physical activity levels were measured using the International Physical Activity Questionnaire and/or the SenseWear Pro3 Armband at four timepoints: before preoperative physiotherapy, the week before surgery, and 3 and 6 weeks postoperatively. Urinary incontinence was measured at 3 and 6 weeks postoperatively using a 24-hour pad test and the International Consultation on Incontinence Questionnaire – Urinary Incontinence Short Form (ICIQ). Results Physical activity levels changed significantly over the perioperative period (p < 0.001). At 6 weeks postoperatively, physical activity levels did not differ significantly from baseline (p = 0.181), but remained significantly lower than the week before surgery (p = 0.002). There was no significant interaction effect between preoperative physical activity category and time on the 24-hour pad test (p = 0.726) or ICIQ (p = 0.608). Nor were there any significant correlations between physical activity levels and the 24-hour pad test and ICIQ at 3 or 6 weeks postoperatively. Conclusions This study provides novel data on perioperative physical activity levels for patients having radical prostatectomy. There was no relationship between perioperative physical activity levels and post-prostatectomy urinary incontinence, although participants had high overall preoperative physical activity levels and low overall urinary incontinence.

In the last few years there have been increasing claims that robotic assisted laparoscopic radical prostatectomy decreases short-term morbidity in patients undergoing surgical treatment for prostate cancer. However, there is surprisingly little objective evidence to support this point, which is often used to market the procedure to patients. To address this issue we prospectively evaluated patients undergoing open and robotic assisted laparoscopic radical prostatectomy at baseline and weekly through the postoperative period using a validated questionnaire. A total of 162 men undergoing radical prostatectomy, including open radical prostatectomy in 120 and robotic assisted laparoscopic radical prostatectomy in 42, for clinically localized prostate cancer completed the SF-12, version 2 Physical and Mental Health Survey Acute Form preoperatively and each week postoperatively for 6 weeks. Physical and Mental Component Scores were calculated from the questionnaires at each time point. Comparisons between the 2 surgical approaches were made at each time point. No significant differences were seen between the open and robotic assisted laparoscopic radical prostatectomy groups with regard to patient age, clinical stage or preoperative prostate specific antigen. Mean surgical blood loss was significantly higher in the open group compared to that in the robotic assisted laparoscopic group. Physical Component Scores in the robotic assisted laparoscopic group were significantly higher than those in the open cohort beginning postoperative week 1 and extending through week 6. On statistical extrapolation Physical Component Scores returned to baseline between weeks 5 and 6 postoperatively in the robotic assisted laparoscopic group and between weeks 6 and 7 in the open group. Mental Component Score scores were not statistically different between the groups except preoperatively. This study helps prospectively define short-term health related quality of life in patients undergoing

Robot-assisted surgery has been rapidly adopted in the U.S. for prostate cancer. Its adoption has been driven by market forces and patient preference, and debate continues regarding whether it offers improved outcomes to justify the higher cost relative to open surgery. We examined the comparative effectiveness of robot-assisted vs open radical prostatectomy in cancer control and survival in a nationally representative population. This population based observational cohort study of patients with prostate cancer undergoing robot-assisted radical prostatectomy and open radical prostatectomy during 2003 to 2012 used data captured in the SEER (Surveillance, Epidemiology, and End Results)-Medicare linked database. Propensity score matching and time to event analysis were used to compare all cause mortality, prostate cancer specific mortality and use of additional treatment after surgery. A total of 6,430 robot-assisted radical prostatectomies and 9,161 open radical prostatectomies performed during 2003 to 2012 were identified. The use of robot-assisted radical prostatectomy increased from 13.6% in 2003 to 2004 to 72.6% in 2011 to 2012. After a median followup of 6.5 years (IQR 5.2-7.9) robot-assisted radical prostatectomy was associated with an equivalent risk of all cause mortality (HR 0.85, 0.72-1.01) and similar cancer specific mortality (HR 0.85, 0.50-1.43) vs open radical prostatectomy. Robot-assisted radical prostatectomy was also associated with less use of additional treatment (HR 0.78, 0.70-0.86). Robot-assisted radical prostatectomy has comparable intermediate cancer control as evidenced by less use of additional postoperative cancer therapies and equivalent cancer specific and overall survival. Longer term followup is needed to assess for differences in prostate cancer specific survival, which was similar during intermediate followup. Our findings have significant quality and cost implications, and provide reassurance regarding the adoption of more

BACKGROUND The effectiveness of surgery versus observation for men with localized prostate cancer detected by means of prostate-specific antigen (PSA) testing is not known. METHODS From November 1994 through January 2002, we randomly assigned 731 men with localized prostate cancer (mean age, 67 years; median PSA value, 7.8 ng per milliliter) to radical prostatectomy or observation and followed them through January 2010. The primary outcome was all-cause mortality; the secondary outcome was prostate-cancer mortality. RESULTS During the median follow-up of 10.0 years, 171 of 364 men (47.0%) assigned to radical prostatectomy died, as compared with 183 of 367 (49.9%) assigned to observation (hazard ratio, 0.88; 95% confidence interval [CI], 0.71 to 1.08; P = 0.22; absolute risk reduction, 2.9 percentage points). Among men assigned to radical prostatectomy, 21 (5.8%) died from prostate cancer or treatment, as compared with 31 men (8.4%) assigned to observation (hazard ratio, 0.63; 95% CI, 0.36 to 1.09; P = 0.09; absolute risk reduction, 2.6 percentage points). The effect of treatment on all-cause and prostate-cancer mortality did not differ according to age, race, coexisting conditions, self-reported performance status, or histologic features of the tumor. Radical prostatectomy was associated with reduced all-cause mortality among men with a PSA value greater than 10 ng per milliliter (P = 0.04 for interaction) and possibly among those with intermediate-risk or high-risk tumors (P = 0.07 for interaction). Adverse events within 30 days after surgery occurred in 21.4% of men, including one death. CONCLUSIONS Among men with localized prostate cancer detected during the early era of PSA testing, radical prostatectomy did not significantly reduce all-cause or prostate-cancer mortality, as compared with observation, through at least 12 years of follow-up. Absolute differences were less than 3 percentage points. (Funded by the Department of Veterans Affairs Cooperative Studies

Recovery of baseline erectile function (EF) after robotic radical prostatectomy in men with high-risk prostate cancer is under-reported. Published studies have selectively reported on low-risk disease using non-validated and poorly defined thresholds for EF recovery. To assess return to baseline EF in men after robotic radical prostatectomy for high-risk prostate cancer. Five hundred thirty-one men underwent robotic radical prostatectomy for high-risk prostate cancer from February 2010 through July 2014. Pre- and postoperative EF was prospectively assessed using the International Index of Erectile Dysfunction (IIEF-5) questionnaire. Multivariate logistic regression analysis determined the effect of age, preoperative function, comorbidities, body mass index, prostate-specific antigen level, cancer stage or grade, nerve-sparing status, adjuvant therapy, and continence on EF return (defined as postoperative return to baseline EF with or without use of phosphodiesterase type 5 inhibitors). Kaplan-Meier analysis and log-rank test were used to analyze return over time. Mann-Whitney U-test was used to compare IIEF-5 scores. Pre- and postoperative EF was assessed using the IIEF-5 Sexual Health Inventory for Men at 3 months, 6 months, 1 year, 2 years, 3 years, and 4 years postoperatively. Overall, return of EF was seen in 23.5% of patients at 18 months. This was significantly increased in men no older than 60 years (P = .024), with a preoperative IIEF-5 score of at least 22 (P = .042), and after undergoing neurovascular bundle preservation (34.9% of patients, P < .001). There was no significant change in IIEF-5 scores from 3 to 36 months in patients who were treated with phosphodiesterase type 5 inhibitors in the non-neurovascular bundle preservation group (P = .87), although there was significant improvement in those receiving second- or third-line therapies (P = .042). Other than preoperative hypertension (P = .03), none of the other comorbidities predicted return of

Orgasm associated incontinence, that is the inadvertent leakage of urine at orgasm, has received little attention in the literature. We evaluated the rate of occurrence of orgasm associated incontinence following radical pelvic surgery as well as its associated factors and predictors. From January 2005 to March 2006, 696 patients were evaluated for post-radical pelvic surgery sexual dysfunction. A database was created, and descriptive statistics, chi-square analysis and logistic regression analysis were used to evaluate associated factors and predictors. Of 475 patients 96 (20%) reported orgasm associated incontinence following radical pelvic surgery. The incidence was significantly less in the cystoprostatectomy group than in the open and laparoscopic radical prostatectomy groups (p <0.05). Orgasm associated incontinence was more commonly found within 12 months following surgery vs greater than 12 months (RR 0.81, 95% CI 0.72-0.92, p <0.01) and in patients with orgasm associated pain (RR 1.09, 95% CI 1.01-1.16, p <0.01) and penile length loss (RR 1.32, 95% CI 1.09-1.59, p <0.01). On multivariate analysis all factors associated on univariate analyses remained predictive. Orgasm associated incontinence was not associated with patient age, the degree of nerve sparing, surgical margin status, seminal vesicle or lymph node involvement, preoperative erectile function, nocturnal erections, libido level or daytime continence. Orgasm associated incontinence occurs in a fifth of men (96 of 475) following radical pelvic surgery. The incidence of orgasm associated incontinence is greater with radical prostatectomy than with radical cystectomy and it is unrelated to the type of prostatectomy performed (open vs laparoscopic). Orgasm associated incontinence is more likely to be reported within year 1 following surgery and in men who complain of orgasmic pain and/or penile shortening.

Orgasm is a neurophysiological event, which produces bulbous cavernous muscle contraction that usually coincided with ejaculation. The aim of this study was to assess the orgasm's presence and quality in patients treated with radical prostatectomy, as well as its impact on quality of life of these patients. The medical records of 152 patients with radical prostatectomy were reviewed retrospectively. Patients were operated between january 1999 and december 01, with an average age of 64.4 (44-75) years and the follow-up period was 33 (21-45) months. 42 (31.6%) patients showed erectile dysfunction (ED) previous to surgery. The research was performed by a personal interview through a questionnaire. 134 patients (96.4%) treated showed post operative ED, 91.6% of patients had stable relationship and 44.4% have sexual intercourse, 23.3% masturbation only and 32.3% no sexual activity. 84 patients (55.2%) were not interested in receiving treatment and 25 (16.4%) referred a reduced libido. Concerning to orgasm sensation, 140 patients (92.1%) preserved a subjectively normal orgasm, 4 (2.6%) referred lack of it and 8 (5.2%) a weakened or anomalous sensation. Furthermore 24 patients (15.7) had urine loss during orgasm. After radical prostatectomy, both the orgasmic function and libido were kept by the majority of patients despite the neuro vascular bundle damaged caused. Only a minority of patients having urine loss, as a consequence of surgical procedure.

It is common for men to develop erectile dysfunction after radical prostatectomy. The anatomy of the rat allows the cavernous nerve (CN) to be identified, dissected, and injured in a controlled fashion. Therefore, bilateral CN injury (BCNI) in the rat model is routinely used to study post-prostatectomy erectile dysfunction. To compare and contrast the available literature on pharmacologic intervention after BCNI in the rat. A literature search was performed on PubMed for cavernous nerve and injury and erectile dysfunction and rat. Only articles with BCNI and pharmacologic intervention that could be grouped into categories of immune modulation, growth factor therapy, receptor kinase inhibition, phosphodiesterase type 5 inhibition, and anti-inflammatory and antifibrotic interventions were included. To assess outcomes of pharmaceutical intervention on erectile function recovery after BCNI in the rat model. The ratio of maximum intracavernous pressure to mean arterial pressure was the main outcome measure chosen for this analysis. All interventions improved erectile function recovery after BCNI based on the ratio of maximum intracavernous pressure to mean arterial pressure results. Additional end-point analysis examined the corpus cavernosa and/or the major pelvic ganglion and CN. There was extreme heterogeneity within the literature, making accurate comparisons between crush injury and therapeutic interventions difficult. BCNI in the rat is the accepted animal model used to study nerve-sparing post-prostatectomy erectile dysfunction. However, an important limitation is extreme variability. Efforts should be made to decrease this variability and increase the translational utility toward clinical trials in humans. Haney NM, Nguyen HMT, Honda M, et al.

Despite the large number of analytical reports regarding the learning curve in the transition from open to robot-assisted radical prostatectomy (RARP), few comparative results with laparoscopic radical prostatectomy (LRP) have been reported. Thus, we evaluated operative and postoperative outcomes in RARP versus 100 simultaneously performed LRPs. A single surgeon had performed more than 1,000 laparoscopic operations, including 415 cases of radical nephrectomy, 85 radical cystectomies, 369 radical prostatectomies, and treatment of 212 other urological tumors, since 2009. We evaluated operative (operation time, intraoperative transfusion, complications, hospital stay, margin status, pathological stage, Gleason score) and postoperative (continence and erectile function) parameters in initial cases of RARP without tutoring compared with 100 recently performed LRPs. Mean operation time and length of hospital stay for RARP and LRP were 145.5±43.6 minutes and 118.1±39.1 minutes, and 6.4±0.9 days and 6.6±1.1 days, respectively (p=0.003 and p=0.721). After 17 cases, the mean operation time for RARP was similar to LRP (less than 2 hours). Positive surgical margins in localized cancer were seen in 11.1% and 8.9% of cases in RARP and LRP, respectively (p=0.733). At postoperative 3 months, sexual intercourse was reported in 14.0% and 12.0%, and pad-free continence in 96.0% and 81.0% in patients with RARP and LRP, respectively (p=0.796 and p=0.012). Previous large-volume experience of LRPs may shorten the learning curve for RARP in terms of oncological outcome. Additionally, previous experience with laparoscopy may improve the functional outcomes of RARP.

To investigate the outcome of preperitoneal inguinal hernia mesh repairs performed during endoscopic extraperitoneal radical prostatectomy (EERPE). Ninety-three patients underwent inguinal hernia repair during 2125 EERPEs performed between 2002 and 2008. Seventy-seven patients had a unilateral hernia and 16 bilateral inguinal hernias. Patients were treated with EERPE or nerve-sparing EERPE and pelvic lymphadenectomy (if indicated) for localized prostate cancer. The mean age of the patients was 63 years (range 49-75 years). Operative time was 150 minutes (range 85-285 minutes) and estimated mean blood loss was 240 mL (range 30-600 mL). Blood transfusion was never deemed necessary. No conversions to open surgery took place. The mean duration of catheterization was 6.5 days (range 4-25 days). One patient developed a pelvic haematoma, three patients had symptomatic pelvic lymphoceles, and one developed an anastomotic stricture. One patient suffered a rectal injury during the procedure and another developed deep venous thrombosis. The only complication of hernia repair was mild penile bruising and edema. During the follow-up period, we have never observed mesh infection or hernia recurrence. EERPE combined with either a unilateral or bilateral laparoscopic hernia repair appears to be a safe and effective procedure. The incidence of complications related to either EERPE or the hernia repair was not increased. Oncological and functional outcome of EERPE seems not to be influenced by the performance of inguinal hernia repair.

To offer a comprehensive account of surgical outcomes on a defined series of patients treated with radical retropubic prostatectomy (RRP) for prostate cancer in a single European Center after 5-year minimum follow-up according to the Survival, Continence and Potency (SCP) system. We evaluated our Institutional database of patients who underwent RRP from November 1995 to September 2008. Oncological and functional outcomes were reported according to the recently proposed SCP system. The 5- and 10-year biochemical recurrence-free survival rates were 80.1% and 55.8%, respectively. At the end of follow-up, 611 (78.5%) patients were fully continent (C0), 107 (13.8%) used 1 pad for security (C1) and 60 (7.7%) patients were incontinent (C2). Of the 112 patients who underwent nerve-sparing RRP, 22 (19.6%) were fully potent without aids (P0), 13 (11.6%) were potent with assumption of PDE-5 inhibitors (P1) and 77 (68.8%) experienced erectile dysfunction (P2). The combined SCP outcomes were reported together only in 95 (12.2%) evaluable patients. In patients preoperatively continent and potent, who received a nerve-sparing and did not require adjuvant therapy, oncological and functional success was attained by 29 (30.5%) patients. In the subgroup of 508 patients not evaluable for potency recovery, oncological and continence outcomes were obtained in 357 patients (70.3%). Survival, Continence and Potency (SCP) classification offer a comprehensive report of surgical results, even in those patients who do not represent the best category, thus allowing to provide a much more accurate evaluation of outcomes after RP.

To provide an update of recent studies relevant to robot-assisted radical prostatectomy, highlighting technical modifications and associated functional outcomes, mid-term oncologic results and patient perception and satisfaction. Several recent studies have investigated methods of further reducing the morbidities associated with prostatectomy, namely erectile dysfunction and incontinence. These studies provide important anatomic insights into additional mechanisms responsible for potency and incontinence and measures for preserving both. Mid-term oncologic outcomes have also been reported; further substantiating the role of robotics in the treatment of clinically localized prostate cancer. The technique of robotic prostatectomy has evolved over the last decade with significant efforts in improving functional outcomes following surgery. However, aggressive-marketing campaigns and lack of regulation of hospital websites may be contributing to unrealistic expectations in patients who choose to undergo robotic prostatectomy, resulting in dissatisfaction for some patients. National interests in this topic will likely result in the mandate for more stringent studies to assess the comparative effectiveness of robot-assisted prostatectomy with other competing therapies for clinically localized prostate cancer.

To evaluate the positive surgical margin rates and locations in radical prostatectomy among three surgical approaches, including open radical prostatectomy, laparoscopic radical prostatectomy and robot-assisted radical prostatectomy. We retrospectively reviewed clinical outcomes at our institution of 450 patients who received radical prostatectomy. Multiple surgeons were involved in the three approaches, and a single pathologist conducted the histopathological diagnoses. Positive surgical margin rates and locations among the three approaches were statistically assessed, and the risk factors of positive surgical margin were analyzed. This study included 127, 136 and 187 patients in the open radical prostatectomy, laparoscopic radical prostatectomy and robot-assisted radical prostatectomy groups, respectively. The positive surgical margin rates were 27.6% (open radical prostatectomy), 18.4% (laparoscopic radical prostatectomy) and 13.4% (robot-assisted radical prostatectomy). In propensity score-matched analyses, the positive surgical margin rate in the robot-assisted radical prostatectomy was significantly lower than that in the open radical prostatectomy, whereas there was no significant difference in the positive surgical margin rates between robot-assisted radical prostatectomy and laparoscopic radical prostatectomy. In the multivariable analysis, PSA level at diagnosis and surgical approach (open radical prostatectomy vs robot-assisted radical prostatectomy) were independent risk factors for positive surgical margin. The apex was the most common location of positive surgical margin in the open radical prostatectomy and laparoscopic radical prostatectomy groups, whereas the bladder neck was the most common location in the robot-assisted radical prostatectomy group. The significant difference of positive surgical margin locations continued after the propensity score adjustment. Robot-assisted radical prostatectomy may potentially achieve the lowest positive

To present our preliminary experience with augmented reality robot-assisted radical prostatectomy (AR-RARP). From June to August 2017, patients candidate to RARP were enrolled and underwent high-resolution multi-parametric magnetic resonance imaging (1-mm slices) according to dedicated protocol. The obtained three-dimensional (3D) reconstruction was integrated in the robotic console to perform AR-RARP. According to the staging at magnetic resonance imaging or reconstruction, in case of cT2 prostate cancer, intrafascial nerve sparing (NS) was performed: a mark was placed on the prostate capsule to indicate the virtual underlying intraprostatic lesion; in case of cT3, standard NS AR-RARP was scheduled with AR-guided biopsy at the level of suspected extracapsular extension (ECE). Prostate specimens were scanned to assess the 3D model concordance. Sixteen patients underwent intrafascial NS technique (cT2), whereas 14 underwent standard NS+ selective biopsy of suspected ECE (cT3). Final pathology confirmed clinical staging. Positive surgical margins' rate was 30% (no positive surgical margins in pT2). In patients whose intraprostatic lesions were marked, final pathology confirmed lesion location. In patients with suspected ECE, AR-guided selective biopsies confirmed the ECE location, with 11 of 14 biopsies (78%) positive for prostate cancer. Prostate specimens were scanned with finding of a good overlap. The mismatch between 3D reconstruction and scanning ranged from 1 to 5 mm. In 85% of the entire surface, the mismatch was <3 mm. In our preliminary experience, AR-RARP seems to be safe and effective. The accuracy of 3D reconstruction seemed to be promising. This technology has still limitations: the virtual models are manually oriented and rigid. Future collaborations with bioengineers will allow overcoming these limitations.

In 2010, we published a review summarising the available literature on surgical anatomy of the prostate and adjacent structures involved in cancer control and the functional outcome of prostatectomy. To provide an update based on new literature to help the surgeon improve oncologic and surgical outcomes of radical prostatectomy (RP). We searched the PubMed database using the keywords radical prostatectomy, anatomy, neurovascular bundle, nerve, fascia, pelvis, sphincter, urethra, urinary continence, and erectile function. Relevant articles and textbook chapters published since the last review were critically reviewed, analysed, and summarised. Moreover, we integrated aspects that were not addressed in the last review into this update. We found new evidence for several topics. Up to 40% of the cross-sectional surface area of the urethral sphincter tissue is laterally overlapped by the dorsal vascular complex and might be injured during en bloc ligation. Denonvilliers fascia is fused with the base of the prostate in a horizontal fashion dorsally/caudally of the seminal vesicles, requiring sharp detachment when preserved. During extended pelvic lymph node dissection, the erectile nerves are at risk in the presacral and internal iliac area. Dissection planes for nerve sparing can be graded according to the amount of tissue left on the prostate as a safety margin against positive surgical margins. Vascular structures can serve as landmarks. The urethral sphincter and its length after RP are influenced by the shape of the apex. Taking this shape into account allows preservation of additional sphincter length with improved postoperative continence. This update provides additional, detailed information about the surgical anatomy of the prostate and adjacent tissues involved in RP. This anatomy remains complex and widely variable. These details facilitate surgical orientation and dissection during RP and ideally should translate into improved outcomes. Based on recent

Few studies have investigated the efficacy and safety of the nerve-sparing approach via minimally invasive surgery for the treatment of cervical cancer. We aimed to review the current evidence comparing nerve-sparing minimally invasive radical hysterectomy (NS-MRH) with conventional minimally invasive radical hysterectomy (MRH). This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD#57655). Overall, 675 patients were included: 350 (51.9%) and 325 (48.1%) patients undergoing MRH and NS-MRH, respectively. MRH was associated with a shorter operative time in comparison with NS-MRH (mean difference = 32.57 minutes; 95% CI, 22.87-42.48). The estimated blood loss (mean difference = 97.14 mL, 20.01-214.29) and transfusion rate (odds ratio [OR] = 0.67; 95% confidence interval [CI], 0.15-3.01) did not differ statistically between the 2 groups. The risk of developing intraoperative (OR = 0.43; 95% CI, 0.08-2.23) and severe postoperative (OR = 0.63; 95% CI, 0.17-2.39) complications was similar between NS-MRH and MRH. Patients undergoing NS-MRH experienced lower voiding (OR = 0.39; 95% CI, 0.19-0.81) dysfunction rates than patients undergoing MRH. Moreover, a trend toward lower sexual (OR = 0.25; 95% CI, 0.06-1.07) and rectal (OR = 0.12; 95% CI, 0.01-1.02) issues was observed for patients having NS-MRH compared with patients undergoing MRH. Survival outcomes are not influenced by the type of surgical approach (recurrence [OR = 1.27; 95% CI, 0.49-3.28] and death [OR = 1.01; 95% CI, 0.36-2.83]) rates. The pooled data suggested that NS-MRH is equivalent to MRH for the treatment of cervical cancer and may be superior in reducing pelvic floor dysfunction rates. However, because of the low level of evidence of the included studies, further randomized trials are warranted. Copyright © 2017 American Association of Gynecologic Laparoscopists.

The purpose of this study was to assess the 5-year survival and morbidity in cases with radical hysterectomy and pelvic lymphadenectomy with pre- and postoperative irradiation performed to treat Stage IA2-IIB cervical cancer. During a 10(1/2)-year period between July 1990 and December 2000, 501 consecutive radical hysterectomies with bilateral pelvic lymphadenectomy were performed by the same gynecological surgeon in Stage IA2, IB, IIA and IIB cervical cancer. The patients were treated by pre- and postoperative irradiation as well. Apart from recurrence, perioperative complications were minimal with no long-term morbidity. The absolute 5-year survival rates for the patients in Stage IA2, IB1, IB2, IIA and IIB were 94.4%, 90.7%, 84.1%, 71.1%, and 55.4%, respectively. The respective 5-year survival rates for patients without or with lymph node metastasis were 94.5% and 33.3% in Stage IB2, 81.7% and 48.7% in Stage IIA and 70.2% and 36.5% in Stage IIB, respectively. Nerve-sparing radical hysterectomy with pelvic lymph node dissection and pre- and postoperative irradiation remains the treatment of choice for most patients with early-stage and even Stage IIB cervical cancer. The radicalism and extent of lymph node dissection and parametrial resection should be individualized and tailored to tumor- and patient-related risk factors.

To investigate predictors of continence outcomes after robot-assisted radical prostatectomy. Clinical records of 272 patients who underwent robot-assisted radical prostatectomy were investigated. Preoperative Overactive Bladder Symptom Score, International Prostate Symptom Score and clinicopathological factors were investigated, and relationships between factors and recovery of continence after robot-assisted radical prostatectomy were assessed. The presence of overactive bladder was defined as having urgency for more than once a week and having ≥3 points according to the Overactive Bladder Symptom Score. Age (≤66 years) was significantly associated with continence within 6 months after robot-assisted radical prostatectomy (P = 0.033). The absence of overactive bladder and lower Overactive Bladder Symptom Score (<3) were significantly associated with recovery of continence within 12 months after surgery (both variables P = 0.009). In terms of achieving recovery of continence after robot-assisted radical prostatectomy, Kaplan-Meier curves showed earlier recovery in "age ≤66 years," "prostate weight ≤40 g" and "overactive bladder symptom score <3" (P = 0.0072, 0.0172 and 0.0140, respectively). Multivariate analysis showed that the presence of overactive bladder was an independent negative predictor for recovery of continence within 12 months after surgery (P = 0.019). The presence of baseline overactive bladder seems to represent an independent negative predictor for recovery of continence at 12 months after robot-assisted radical prostatectomy. © 2017 The Japanese Urological Association.

We compare the comprehensive 1-year charges in a consecutive group of patients undergoing radical prostatectomy and transperineal interstitial brachytherapy for clinically localized prostate cancer at a single urban institution. A total of 60 consecutive men with clinically localized prostate cancer (T1-T2, N0, M0) were treated during a 15-month period with radical prostatectomy or interstitial brachytherapy. Hospital and outpatient records were analyzed for each patient in regard to preoperative, operative and postoperative charges. Parameters included number of encounters, diagnostic and therapeutic interventions, hospitalization and operative charges, and followup visits, diagnostic tests and interventions for 1 year. All charge calculations were based arbitrarily on the 1996 Medicare fee schedule, factoring in the mandated global charge reimbursement period of 90 days for both procedures. Of the patients 38 underwent radical prostatectomy (prostatectomy group) and 22 underwent interstitial brachytherapy (brachytherapy group). The brachytherapy group was older with higher pretreatment serum prostate specific antigen and clinical stage disease, and more frequently received neoadjuvant hormonal therapy compared to the prostatectomy group. The 2 groups were similar in Gleason score and, when applicable, duration of neoadjuvant hormonal therapy. Preoperative charges were 15.3% lower for prostatectomy than for brachytherapy (not statistically significant). Conversely, operative charges for prostatectomy were 13.5% higher (p = 0.04). The major difference among preoperative, operative and postoperative charges was for those incurred postoperatively by the brachytherapy group, which were 56.0% higher than those for the prostatectomy group ($2,285.20 versus $1,007.20, p = 0.0004). Transperineal interstitial seed implantation is perceived by many as more cost-effective than radical prostatectomy for patients with clinically localized prostate cancer. We demonstrated that

Radical prostatectomy is associated with perioperative bleeding and multiple transfusions. Abdominal obesity is a perioperative risk factor. We suggest that the adipocytes have a protective effect in oncological patients undergoing radical prostatectomy. The aim was to evaluate the effect of waist-hip ratio (WHR) on the amount of bleeding and perioperative transfusion requirements in oncological patients undergoing radical prostatectomy. We performed a cohort study in 156 patients. We had two groups: the control group (WHR<0.95) and the problem group (WHR≥0.95). Blood loss and fractions transfused during surgery and in the postoperative period were recorded. In the analysis of variables, for descriptive statistics we used measures of central tendency and dispersion. Inferential statistics was obtained by chi square, Student's t test, Mann-Whitney U and ANOVA. A p<0.05 was significant. We found significant differences in weight, body mass index, waist, WHR, perioperative bleeding, fractions transfused, permanence of the catheter, and hospital days. Patients who underwent radical prostatectomy with a WHR≥0.95 had a magnitude of perioperative bleeding and transfusion requirements with a WHR<0.95.

There has been an increase in the number of urologic procedures performed robotically assisted; this is the case for radical prostatectomy. Currently, in the USA, 67% of prostatectomies are performed robotically assisted. With this increase in robotic urologic surgery it is clear that there are more surgeons in their learning curve, where most of the complications occur. Among the complications that can occur are vascular injuries. These can occur in the initial stages of surgery, such as in accessing the abdominal cavity, as well as in the intraoperative or postoperative setting. We present the most common vascular injuries in robot-assisted radical prostatectomy, as well as their management and prevention. We believe that it is of vital importance to be able to recognize these injuries so that they can be prevented. PMID:25642293

To determine the extent of variability in the definitions of the 'trifecta' after radical prostatectomy (undetectable PSA, urinary continence and potency) to be found in the literature. To establish a consensus definition of the trifecta in an effort to standardize criteria and reporting. A systematic review of published articles found in the PubMed database for the period from January 2003 to March 2012 was performed. The search queries included the keywords 'radical prostatectomy,' 'prostatectomy outcome,' and 'trifecta'. A total of 86 publications were identified of which 14 were used for analysis. Eight different definitions of biochemical recurrence were reported, the most common definition being PSA ≥0.2 ng/mL. The definition of potency was the most variable. Ten different definitions of potency were found, with the most common being 'having erections sufficient for intercourse with or without a phosphodiesterase-5 inhibitor'. Nine different definitions of continence were found. The most common definition of continence was 'wearing no pads'. Only six of the 14 articles used validated questionnaires in their outcome measures. The definitions of trifecta reported in the literature are highly variable. We propose the following consensus definition based on our analysis: (1) PSA >0.2 ng/mL with confirmatory value; (2) attainment of erections sufficient for intercourse with or without oral pharmacological agents; (3) wearing zero pads. This consensus definition should be considered when designing studies and reporting outcomes of radical prostatectomy. © 2013 BJU International.

Purpose To develop a microRNA (miRNA)-based predictive model for prostate cancer patients of 1) time to biochemical recurrence after radical prostatectomy and 2) biochemical recurrence after salvage radiation therapy following documented biochemical disease progression post-radical prostatectomy. Methods Forty three patients who had undergone salvage radiation therapy following biochemical failure after radical prostatectomy with greater than 4 years of follow-up data were identified. Formalin-fixed, paraffin-embedded tissue blocks were collected for all patients and total RNA was isolated from 1mm cores enriched for tumor (>70%). Eight hundred miRNAs were analyzed simultaneously using the nCounter human miRNA v2 assay (NanoString Technologies; Seattle, WA). Univariate and multivariate Cox proportion hazards regression models as well as receiver operating characteristics were used to identify statistically significant miRNAs that were predictive of biochemical recurrence. Results Eighty eight miRNAs were identified to be significantly (p<0.05) associated with biochemical failure post-prostatectomy by multivariate analysis and clustered into two groups that correlated with early (≤ 36 months) versus late recurrence (>36 months). Nine miRNAs were identified to be significantly (p<0.05) associated by multivariate analysis with biochemical failure after salvage radiation therapy. A new predictive model for biochemical recurrence after salvage radiation therapy was developed; this model consisted of miR-4516 and miR-601 together with, Gleason score, and lymph node status. The area under the ROC curve (AUC) was improved to 0.83 compared to that of 0.66 for Gleason score and lymph node status alone. Conclusion miRNA signatures can distinguish patients who fail soon after radical prostatectomy versus late failures, giving insight into which patients may need adjuvant therapy. Notably, two novel miRNAs (miR-4516 and miR-601) were identified that significantly improve

Radical prostatectomy (RP) is curative for localized prostatic cancer. Incontinence after RP (P-RP-I) varies widely (2% to <60%) according to the definition and quantification of incontinence, timing of evaluation, and who evaluates (physician or patient). Conservative treatments, including pelvic floor muscle training (PFMT), anal electrical stimulation (AES), lifestyle adjustment, or combination are usually recommended at first for P-RP-I. Between January 2002 and December 2004, a total of 911 patients, median age 63 years (46-78), with different grades of P-RP-I have been retrospectively examined for perioperative risk factors and effect of rehabilitation procedures. These consecutive patients were from 67 clinics with median postoperative interval of 26 days. Incontinence was graded by Stamey classification, number of used pads and pads' consistency (dry, lightly wet, and wet). Therapeutic measures were done by team of specialists in rehabilitation, psycho-oncology, physiotherapy, internal medicine, and urology. Ninety-six percent of patients suffered different grades of incontinence at beginning of hospitalization. This was reported as Stamey first grade (49.4%), second grade (36.4%), and third grade (10.3%). Analysis included patients' age, body mass index (BMI), prostate volume, surgical approach, nerve sparing, pelvic lymphadenectomy, previous therapy, and catheterization time. Analysis showed age, nerve sparing, and BMI as significant risk factors for P-RP-I. Conservative therapy, including PFMT, AES, or combinations has been performed on all patients. Grade of P-RP-I showed significant improvement after 3 weeks rehabilitation period. Preoperative counseling of patients should provide them with realistic expectations for P-RP-I and motivate them to conservative therapy, as it reduces the duration and degree of urinary incontinence.

Radical prostatectomy is the most common treatment for localised prostate cancer in New Zealand. Active surveillance was introduced to prevent overtreatment and reduce costs while preserving the option of radical prostatectomy. This study aims to evaluate the cost-effectiveness of active surveillance compared to watchful waiting and radical prostatectomy. Markov models were constructed to estimate the life-time cost-effectiveness of active surveillance compared to watchful waiting and radical prostatectomy for low risk localised prostate cancer patients aged 45-70 years, using national datasets in New Zealand and published studies including the SPCG-4 study. This study was from the perspective of the Ministry of Health in New Zealand. Radical prostatectomy is less costly than active surveillance in men aged 45-55 years with low risk localised prostate cancer, but more costly for men aged 60-70 years. Scenario analyses demonstrated significant uncertainty as to the most cost-effective option in all age groups because of the unavailability of good quality of life data for men under active surveillance. Uncertainties around the likelihood of having radical prostatectomy when managed with active surveillance also affect the cost-effectiveness of active surveillance against radical prostatectomy. Active surveillance is less likely to be cost-effective compared to radical prostatectomy for younger men diagnosed with low risk localised prostate cancer. The cost-effectiveness of active surveillance compared to radical prostatectomy is critically dependent on the 'trigger' for radical prostatectomy and the quality of life in men on active surveillance. Research on the latter would be beneficial.

Surgery for prostate cancer has a large impact on quality of life (QoL). To evaluate predictors for the level of self-assessed QoL at 3 mo, 12 mo, and 24 mo after robot-assisted laparoscopic (RALP) and open radical prostatectomy (ORP). The LAParoscopic Prostatectomy Robot Open study, a prospective, controlled, nonrandomised trial of more than 4000 men who underwent radical prostatectomy at 14 centres. Here we report on QoL issues after RALP and ORP. The primary outcome was self-assessed QoL preoperatively and at 3 mo, 12 mo, and 24 mo postoperatively. A direct validated question of self-assessed QoL on a seven-digit visual scale was used. Differences in QoL were analysed using logistic regression, with adjustment for confounders. QoL did not differ between RALP and ORP postoperatively. Men undergoing ORP had a preoperatively significantly lower level of self-assessed QoL in a multivariable analysis compared with men undergoing RALP (odds ratio: 1.21, 95% confidence interval: 1.02-1.43), that disappeared when adjusted for preoperative preparedness for incontinence, erectile dysfunction, and certainty of being cured (odds ratio: 1.18, 95% confidence interval: 0.99-1.40). Incontinence and erectile dysfunction increased the risk for poor QoL at 3 mo, 12 mo, and 24 mo postoperatively. Biochemical recurrence did not affect QoL. A limitation of the study is the nonrandomised design. QoL at 3 mo, 12 mo, and 24 mo after RALP or ORP did not differ significantly between the two techniques. Poor QoL was associated with postoperative incontinence and erectile dysfunction but not with early cancer relapse, which was related to thoughts of death and waking up at night with worry. We did not find any difference in quality of life at 3 mo, 12 mo, and 24 mo when open and robot-assisted surgery for prostate cancer were compared. Postoperative incontinence and erectile dysfunction were associated with poor quality of life. Copyright © 2017 European Association of Urology. Published

To assess trends in the distribution of patients for radical prostatectomy in Germany from 2006 to 2013 and the impact of robotic surgery on annual caseloads. We hypothesized that the advent of robotics and the establishment of certified prostate cancer centers caused centralization in the German radical prostatectomy market. Using remote data processing we analyzed the nationwide German billing data from 2006 to 2013. We supplemented this database with additional hospital characteristics like the prostate cancer center certification status. Inclusion criteria were a prostate cancer diagnosis combined with radical prostatectomy. Hospitals with certification or a surgical robot in 2009 were defined as 'early' group. Linear covariant-analytic models were applied to describe trends over time. Annual radical prostatectomy numbers declined from 28 374 (2006) to 21 850 (2013). High-volume hospitals (⩾100 cases) decreased from 87 (22.0%) in 2006 to 43 (10.4%) in 2013. Low-volume hospitals (<50 cases) increased from 193 (48.7%) to 280 (67.4%). Mean radical prostatectomy caseloads of hospitals with early vs without certification declined from 155 to 130 vs 77 to 39 (P=0.021 for trend comparison). Early robotic hospitals maintained their volume >200 cases per year contrary to the overall trend (P<0.001 for trend comparison). A multivariate model for caseload numbers of 2013 indicated a robotic system to be the most important factor for higher caseloads (multiplication factor 7.3; 95% confidence interval: 6.6-8.0). A prostate cancer center certification (multiplication factor 1.6; 95% confidence interval: 1.50-1.59) had a much smaller impact. We found decentralization of radical prostatectomy in Germany. The driving force for this development might consist in the overall decline of radical prostatectomy numbers. The most important factor for achieving higher caseloads was the presence of a robotic system. In order to optimize outcomes of radical prostatectomy additional

Positive surgical margins are an independent predictive factor for biochemical recurrence after radical prostatectomy. We analyzed the incidence of and associative factors for positive surgical margins in a multi-institutional series of 8,418 robotic assisted radical prostatectomies. We analyzed the records of 8,418 patients who underwent robotic assisted radical prostatectomy at 7 institutions. Of the patients 323 had missing data on margin status. Positive surgical margins were categorized into 4 groups, including apex, bladder neck, posterolateral and multifocal. The records of 6,169 patients were available for multivariate analysis. The variables entered into the logistic regression models were age, body mass index, preoperative prostate specific antigen, biopsy Gleason score, prostate weight and pathological stage. A second model was built to identify predictive factors for positive surgical margins in the subset of patients with organ confined disease (pT2). The overall positive surgical margin rate was 15.7% (1,272 of 8,095 patients). The positive surgical margin rate for pT2 and pT3 disease was 9.45% and 37.2%, respectively. On multivariate analysis pathological stage (pT2 vs pT3 OR 4.588, p<0.001) and preoperative prostate specific antigen (4 or less vs greater than 10 ng/ml OR 2.918, p<0.001) were the most important independent predictive factors for positive surgical margins after robotic assisted radical prostatectomy. Increasing prostate weight was associated with a lower risk of positive surgical margins after robotic assisted radical prostatectomy (OR 0.984, p<0.001) and a higher body mass index was associated with a higher risk of positive surgical margins (OR 1.032, p<0.001). For organ confined disease preoperative prostate specific antigen was the most important factor that independently correlated with positive surgical margins (4 or less vs greater than 10 ng/ml OR 3.8, p<0.001). The prostatic apex followed by a posterolateral site was the most

There are few studies evaluating multiple variables on sextant biopsies with the intent to predict stage in radical prostatectomy specimens. We studied 113 sextant biopsies with corresponding totally submitted radical prostatectomy specimens. Variables evaluated on sextant biopsies included total length and percent of cancer; maximum length and percent of cancer on one core; location (apex, mid, base); bilaterality; Gleason grade; number of cores involved; serum prostate-specific antigen (PSA) level; and serum PSA density (PSAD). Radical prostatectomy stage was classified as organ versus non-organ confined. The following variables individually correlated with radical prostatectomy stage: total cancer measured in millimeters (P <0.0001) or percent (P <0.0005); biopsy Gleason score (P <0.0001); number of involved cores (P <0.0001); maximum cancer on one core measured in millimeters (P = 0.0001); maximum percent of cancer on one core (P = 0.01); bilaterality (P = 0.01); PSA level (P = 0.03), and PSAD (P = 0.001). The most predictive sets of two variables that correlated with stage included high Gleason score (P <0.0001) combined with numbers of cores involved (P = 0.002). When biopsies had Gleason scores of 6 or less, two or fewer positive cores, and serum PSA of 0 to 4 ng/mL, 89% were organ confined. When biopsies had Gleason scores of 6 or less with two unilaterally positive cores, 87% were organ confined. In biopsies with Gleason scores of 7 or more and more than one positive core, only 10% were organ confined. The most important predictors of stage by sextant needle biopsy evaluation are numbers of cores involved with carcinoma and high Gleason score. Bilaterality and serum PSA values improved prediction in two small subgroups. In 37% of our population we were able to predict with a greater than 87% probability the organ-confined versus non-organ-confined status.

To analyze the importance of the starting time for pelvic floor physiotherapy in patients with post radical prostatectomy urinary incontinence. Between May 2003 and February 2004 18 patients with the diagnosis of post radical prostatectomy urinary incontinence underwent physiotherapy of the pelvic floor. Each patient received 12 sessions using kinesotherapy and electric stimulation on a weekly basis. Patients were divided into two groups: Group 1 included eight patients that started therapy within the first six months after surgery; Group 2 included 10 patients starting therapy after the sixth post operative month. All patients were evaluated by the pad test and number of incontinence pads per day. Evaluating pad tests before and after treatment, six patients in group 1 had a reduction of the amount of urine leak in comparison to seven patients in group 2. The statistical analysis showed significant differences before and after treatment for both groups (group 1: p = 0.028; group 2: p = 0.018). The evaluation of the number of pads showed: Group 1: all eight patients using pods had a reduction in the number of pads. Group 2: 5 of the eight patients using pads had a reduction and the other three continued using the same number. Statistical analysis comparing the number of pads per day before and after treatment showed a significant difference in group 1 (p = 0.004). There was no statistically significant difference in the number of pads per day before and after physiotherapy in group 2, although half of the patients showed a diminishment in the number of pads required after treatment. Results demonstrate that early indication of physiotherapy for the treatment of post radical prostatectomy urinary incontinence is better than delayed treatment. New works may be developed in the future to confirm our results.

Involuntary release of urine during sexual climax, orgasm-associated urinary incontinence, occurs frequently after radical prostatectomy. We know little about its prevalence and its effect on sexual satisfaction. To determine the prevalence of orgasm-associated incontinence after radical prostatectomy and its effect on sexual satisfaction. Consecutive series, follow-up at one point in calendar time of men having undergone radical prostatectomy (open surgery or robot-assisted laparoscopic surgery) at Karolinska University Hospital, Stockholm, Sweden, 2002-2006. Of the 1,411 eligible men, 1,288 (91%) men completed a study-specific questionnaire. Prevalence rate of orgasm-associated incontinence. Of the 1,288 men providing information, 691 were sexually active. Altogether, 268 men reported orgasm-associated urinary incontinence, of whom 230 (86%) were otherwise continent. When comparing them with the 422 not reporting the symptom but being sexually active, we found a prevalence ratio (with 95% confidence interval) of 1.5 (1.2-1.8) for not being able to satisfy the partner, 2.1 (1.1-3.5) for avoiding sexual activity because of fear of failing, 1.5 (1.1-2.1) for low orgasmic satisfaction, and 1.4 (1.2-1.7) for having sexual intercourse infrequently. Prevalence ratios increase in prostate-cancer survivors with a higher frequency of orgasm-associated urinary incontinence. We found orgasm-associated urinary incontinence to occur among a fifth of prostate cancer survivors having undergone radical prostatectomy, most of whom are continent when not engaged in sexual activity. The symptom was associated with several aspects of sexual life. © 2011 International Society for Sexual Medicine.

Laparoscopic radical prostatectomy (LRP) is a relatively new technique for treating organ-confined prostate cancer. Recent progress of laparoscopic/endoscopic techniques allow to perform these complex oncological procedure. Since the first description of LRP in the early 1990s the technique has undergone significant technical modifications. Two operation routes were mainly used: the transperitoneal LRP and the extraperitoneal endoscopic radical prostatectomy (EERPE). Here we review the surgical techniques of both operation routes, and highlight results, outcome and complications. The transperitoneal LRP and the EERPE can be used successfully and reproducibly, giving results comparable with those from the open retropubic procedure. Despite many advantages, transperitoneal LRP is associated with potential intraperitoneal complications. The technical improvements of the EERPE completely obviates these complications. The available data are encouraging and promising, but long-term oncological results will define the definitive role of these new techniques. We truly believe that minimally invasive surgery in treating localized prostate cancer has a bright future and that these techniques will continue to be developed.

Success in the era of value-based payment will depend on the capacity of health systems to improve quality while controlling costs. Comparative quality performance review can be used to drive improvements in surgical outcomes and thereby reduce costs. We sought to determine the efficacy of a comparative quality performance review to improve a surgeon-level measure of surgical oncologic quality, that is the positive surgical margin rate at the time of radical prostatectomy. Eight surgeons who performed consecutive radical prostatectomies at a single high volume institution between January 1, 2015 and December 31, 2015 were included in analysis. Individual surgeons were provided with confidential report cards every 6 months detailing their case mix, case volume and pT2 radical prostatectomy positive surgical margin rate relative to 1) their own self-matched data, 2) the de-identified data of their colleagues and 3) institutional aggregate data during the study period. Positive surgical margin rates were compared before and after intervention. Hierarchal logistic regression analysis was used to examine the association of study period on the odds of positive surgical margins, adjusted for prostate specific antigen level and National Comprehensive Cancer Network® risk group. Overall, 1,822 (1,392 before and 430 after intervention) radical prostatectomies were performed that met study inclusion criteria. The aggregate departmental unadjusted positive surgical margin rates were 10.6% and 7.4% in the pre-intervention and post-intervention groups, respectively. After adjusting for higher risk cancer in the post-intervention group, there was a significant protective association of post-intervention status on positive margins (OR 0.64, 95% CI 0.43-0.97, p = 0.03). All 5 surgeons with positive surgical margin rates higher than the aggregate department rate in the pre-intervention period showed improvement after intervention.

Robotic-assisted laparoscopic radical prostatectomy (RLRP) is increasingly becoming an alternative to open and laparoscopic radical prostatectomy in the treatment of localized prostate cancer. RLRP has been associated with low morbidity, short convalescence and comparable oncologic and functional outcomes. We report our initial experience of 300 consecutive cases with selective use of interfascial nerve preservation (IFNP). Between February 2003 and September 2005, 300 consecutive men underwent RLRP at our institution. Patients were followed prospectively with validated questionnaires. Mean operative time was 282 minutes with an estimated blood loss of 273 ml. The intra-operative complication rate was 2.3% with no mortality. Return to baseline (RTB) urinary function and subjective continence at 12 months were 71% and 90.2%, respectively. RTB sexual function and subjective potency at 12 months were 53% and 80.4%, respectively. Overall, the positive surgical margin (PSM) rate was 20.9%: 15.1% for pT2 and 52.1% for pT3 disease and 93.1% had an undetectable PSA (<0.1 ng/mL) with a mean follow-up of 17.3 months. Fifty-four percent of PSMs occured in a poster-lateral (PL) location. Retrospectively, IFNP was performed in 86.5% and 62.5% of pT2 and pT3 PSMs, respectively. Pathologic-T3 PSMs were found to occur significantly more often in a PL location when ipsilateral IFNP was performed when compared to non-IFNP (73% vs 33%, p=0.05). IFNP appears to result in favorable return of potency, however, postero-lateral PSMs appear to occur more frequently with this technique. Proper patient selection for robotic surgery and nerve-preservation appears to be critical in order to reduce PSM and optimize the oncologic efficacy of this technology.

The litigious nature of the medical-legal environment is a major concern for American physicians with an estimated cost of $10 billion. In this study we identify the causes of litigation in cases of radical prostatectomy as well as the factors that contribute to verdicts or settlements resulting in indemnity payments. Publicly available verdict reports were recorded using the Westlaw® legal database. To identify pertinent cases we used the search terms "medical malpractice" and "prostate" or "prostatectomy" with dates ranging from 2000 to 2013. Cases were evaluated for alleged cause of malpractice, resulting injury, findings and indemnity payment (if any). The database search yielded 222 cases, with 25 being relevant to radical prostatectomy. Of these cases 24.0% were settled out of court and the remaining 76.0% went to trial. Of those cases that went to trial 20.8% saw patients awarded damages. There was no significant difference in awards between verdict and settlement. Overall 36.0% of patients claimed that they did not receive proper informed consent and 16.0% claimed that the surgery was not the proper standard of care. Thirteen of the cases claimed negligence in the performance of the surgery with the bulk of these claims being the result of rectal perforation. The main issues that arise in radical prostatectomy malpractice litigation are those of informed consent and clinical performance. Comprehensive preoperative counseling, when combined with proper surgical technique, may minimize the impact of litigation.

To evaluate the impact of prostate weight (PW) on probability of positive surgical margin (PSM) in patients undergoing robotic-assisted radical prostatectomy (RARP) for low-risk prostate cancer. The cohort consisted of 690 men with low-risk prostate cancer (clinical stage T1c, prostate-specific antigen <10 ng/mL, biopsy Gleason score ≤6) who underwent RARP with bilateral nerve-sparing at our institution by 1 of 2 surgeons from 2003 to 2009. PW was obtained from the pathologic specimen. The association between probability of PSM and PW was assessed with univariate and multivariate logistic regression analysis. A PSM was identified in 105 patients (15.2%). Patients with PSM had significant higher prostate-specific antigen (P = .04), smaller prostates (P = .0001), higher Gleason score (P = .004), and higher pathologic stage (P < .0001). After logistic regression, we found a significant inverse relation between PSM and PW (OR 0.97%; 95% confidence interval [CI] 0.96, 0.99; P = .0003) in univariate analysis. This remained significant in the multivariate model (OR 0.98%; 95% CI 0.96, 0.99; P = .006) adjusting for age, body mass index, surgeon experience, pathologic Gleason score, and pathologic stage. In this multivariate model, the predicted probability of PSM for 25-, 50-, 100-, and 150-g prostates were 22% (95% CI 16%, 30%), 13% (95% CI 11%, 16%), 5% (95% CI 1%, 8%), and 1% (95% CI 0%, 3%), respectively. Lower PW is independently associated with higher probability of PSM in low-risk patients undergoing RARP with bilateral nerve-sparing. Copyright © 2011 Elsevier Inc. All rights reserved.

To evaluate the impact of metabolic syndrome on the early recovery of urinary continence after robot-assisted radical prostatectomy. The present study included a total of 302 consecutive Japanese patients with clinically localized prostate cancer who underwent robot-assisted radical prostatectomy. In this study, postoperative urinary continence was defined as no leak or the use of a security pad. The continence status was assessed by interviews before and 1 and 3 months after robot-assisted radical prostatectomy. Metabolic syndrome was defined as follows: body mass index ≥25 kg/m 2 and two or more of the following: hypertension, diabetes mellitus and dyslipidemia. The effect of the presence of metabolic syndrome on the continence status of these patients was retrospectively examined. A total of 116 (38.4%) and 203 (67.2%) of the 302 patients were continent at 1 and 3 months after robot-assisted radical prostatectomy, respectively. A total of 31 (10.3%) patients were judged to have metabolic syndrome. Despite the operative time being longer in patients with metabolic syndrome, no significant differences were observed in the remaining preoperative, intraoperative or postoperative variables between patients with or without metabolic syndrome. On multivariate logistic regression analysis, metabolic syndrome and the duration of hospitalization were significantly correlated with the 1-month continence status. Similarly, metabolic syndrome and estimated blood loss during surgery were independent predictors of continence rates at 3 months after robot-assisted radical prostatectomy. These findings suggest that the presence of metabolic syndrome could have a significant impact on the early recovery of urinary continence after robot-assisted radical prostatectomy. © 2017 The Japanese Urological Association.

To compare the length of the membranous (functional) urethra in male patients who underwent the male transobturator sling (TOS) for postradical prostatectomy urinary incontinence (PPI). The TOS is in established use for treatment of PPI; however, the precise mechanism of action is unknown. This is a prospective case-controlled study on men undergoing male TOS surgery from 2008 to 2014. The comparison arm included patients without incontinence after radical prostatectomy. All participants underwent dynamic magnetic resonance imaging (MRI) at baseline and this was repeated after TOS placement for those who underwent the procedure. Three standardized points were measured using MRI and compared in both groups in addition to clinical measures. Thirty-nine patients were enrolled and 31 patients completed the protocols. The controls (N = 14) had a longer vesicourethral anastomosis to urethra measured at the penile bulb (functional urethral length) distance compared to the pre-TOS group at rest (1.92 cm controls vs 1.27 cm pre-TOS, P = .0018) and at Valsalva (2.13 cm controls vs 1.72 cm pre-TOS, P = .0371). Placement of the sling (N = 17) increased the functional urethral length distance at rest (1.92 cm control vs 1.53 cm post-TOS, P = .09) and at Valsalva (1.94 cm post-TOS vs 2.13 cm control, P = .61), so that the difference was no longer statistically significant. We identified that one possible mechanism in improvement in stress urinary incontinence post-TOS placement is the lengthening of the vesicourethral anastomosis to bulbar-urethra distance. This is the first such study utilizing dynamics MRI in post prostatectomy controls, incontinent pre-TOS, and post-TOS to assess and show these findings. Copyright © 2018 Elsevier Inc.

To evaluate in a prospective, controlled, nonrandomized study the surgical stress and acute-phase systemic response in robotic-assisted laparoscopic prostatectomy (RALP) compared to open radical retro-pubic prostatectomy (ORRP) by measuring humoral mediators. Forty consecutive patients undergoing either RALP or ORRP were prospectively included to assess the extent of systemic response. Blood samples were collected before surgery (T1), at the time of prostatectomy (T2), at the time of wound closure (T3), and 12 h (T4), 24 h (T5), and 48 h (T6) after surgery, and assayed for interleukins (IL-6 and IL-10), C-reactive protein (CRP), and hemoglobin. A 2-sided p < 0.05 was considered to indicate significance. Baseline levels of IL-6, IL-10, and CRP were comparable in both arms of the study. IL-6 and IL-10 increased in both groups during surgery and reached maximum levels at 12 and 24 h after surgery. The RALP and RRP groups differed significantly at T2 (p = 0.009), T3 (p = 0.046), T5 (p = 0.05) and T6 (p = 0.0007) for IL-6, and at T3 (p = 0.05) and T4 (p = 0.05) for IL-10. CRP levels differed significantly at 48 h postoperative (p = 0.0053). The maximum levels of all 3 mediators in the RALP group were significantly lower than those in the open surgery group. Patients in the RALP group experienced less pain from day 2 to 4 according to the Visual Analog Scale (p < 0.05). The study suggests that IL-6 and IL-10 are useful objective markers for surgical stress and that tissue trauma and activation of post-aggression metabolism seem to be less in RALP compared to ORRP. © 2017 S.

Robotic surgery has been widely adopted for radical prostatectomy. We hypothesized that this change is rapidly shifting procedures away from hospitals that do not offer robotics and consequently increasing patient travel. A population-based observational study of all prostatectomies for cancer in New York, New Jersey, and Pennsylvania from 2000 to 2009 was performed using hospital discharge data. Hospital procedure volume was defined as the number of prostatectomies performed for cancer in a given year. Straight-line travel distance to the treating hospital was calculated for each case. Hospitals were contacted to determine the year of acquisition of the first robot. From 2000 to 2009, the total number of prostatectomies performed annually increased substantially. The increase occurred almost entirely at the very high-volume centers (≥ 106 prostatectomies/year). The number of hospitals performing prostatectomy fell 37% from 2000 to 2009. By 2009, the 9% (21/244) of hospitals that had very high volume performed 57% of all prostatectomies, and the 35% (86/244) of hospitals with a robot performed 85% of all prostatectomies. The median travel distance increased 54% from 2000 to 2009 (P<.001). The proportion of patients traveling ≥ 15 miles increased from 24% to 40% (P < .001). Over the past decade, the number of radical prostatectomies performed has risen substantially. These procedures have been increasingly centralized at high-volume centers, leading to longer patient travel distances. Few prostatectomies are now performed at hospitals that do not offer robotic surgery. Copyright © 2011 American Cancer Society.

Objective. We sought to compare positive surgical margin rates (PSM), estimated blood loss (EBL), and quality of life outcomes (QOL) among perineal (RPP), retropubic (RRP), and robot-assisted laparoscopic (RALP) prostatectomies. Methods. Records from 463 consecutive men undergoing RPP (92), RRP (180), or RALP (191) for clinically localized prostate cancer were retrospectively reviewed. Age, percent tumor volume, Gleason score, stage, EBL, PSM, and QOL using the expanded prostate cancer index composite (EPIC) were compared. Results. PSM were similar when adjusted for stage, grade, and volume. EBL was significantly less in the RALP (189 ml) group compared to both RPP (475 ml) and RRP (999 ml) groups. When corrected for nerve sparing, there were no differences in erectile function and sexual function amongst the three groups. Urinary summary and pad usage scores showed no significant differences. Conclusion. RPP, RRP, and RALP offer similar surgical and QOL outcomes. RALP and RPP demonstrate less EBL compared to RRP. PMID:22111001

The objective of this study is to compare the quality of life (QOL) outcomes between laparoscopic radical prostatectomy (LRP) and robot-assisted radical prostatectomy (RARP). Between July 2007 and July 2013, 229 patients with localized prostate cancer underwent LRP while 105 patients with localized prostate cancer underwent RARP between December 2012 and August 2014. We evaluated their QOL using the 8-item Short-Form Health Survey (SF-8) and Expanded Prostate Cancer Index of Prostate (EPIC) questionnaires at preoperative and at postoperative 3, 6 and 12 months. In the LRP and RARP groups, over 80 and 90% of patients answered questionnaires at each follow-up time, respectively. At baseline QOL of EPIC and SF-8, there was no significant difference between LRP and RARP groups. At postoperative 3 months, Physical and Mental Components of SF-8 and Urinary Summary (U), all Urinary Subscales, Sexual Function and Bowel Function of EPIC showed significantly better scores in RARP group than in LRP group. At postoperative 6 and 12 months, there were no differences between LRP and RARP groups in terms of all QOL scores. RARP group showed better scores in SF-8 as well as urinary and sexual function of EPIC at postoperative-3 months. These differences disappeared at postoperative 6 and 12 months.

To evaluate the role of simultaneous laparoscopic mesh prosthetic hernioplasty during laparoscopic radical prostatectomy (LRP), because 5% to 10% of candidates for radical prostatectomy present with a detectable inguinal hernia at their preoperative physical examination. Moreover, data have suggested a greater incidence of inguinal hernia after open radical prostatectomy. During 1035 LRP procedures, 50 laparoscopic mesh prosthetic hernioplasty procedures were performed in 37 patients (3.6%) for 13 bilateral and 24 unilateral inguinal hernias. We compared the outcome of LRP with simultaneous laparoscopic inguinal hernioplasty (group 1) with that of 37 match-paired patients treated by LRP alone (group 2). Both groups were matched according to age, prostate-specific antigen level, prostate volume, pathologic stage, and Gleason score. Perioperative parameters (ie, operative time, analgesic requirements) and postoperative results were analyzed. The patient age was 64.1 +/- 6.4 years versus 62.8 +/- 4.9 years old and had a body mass of 26.5 +/- 3.0 versus 27.4 +/- 3.2 kg/m2 in groups 1 and 2 (with and without laparoscopic hernioplasty), respectively. The mean operating time (221.9 versus 191.2 minutes, P = 0.011) and the total amount of narcotic analgesic requirements (26.8 mg versus 17.5 mg, P = 0.026) was significantly increased in the patients who underwent simultaneous laparoscopic inguinal hernia mesh repair. No statistically significant difference was found in the complication rate (4% versus 2%), median catheter time (7 days), and positive surgical margins (21.8%). Simultaneous repair of inguinal hernia during LRP using prosthetic mesh is feasible without adverse effects on surgical and functional parameters. Neither the transperitoneal nor extraperitoneal approach is associated with an increase in complications or morbidity. However, an extraperitoneal access allows an easier repair without the refixation of the peritoneum.

To study the effect of end-expiratory pressure used during anesthesia on blood loss during radical prostatectomy. We evaluated 247 patients who underwent either radical retropubic prostatectomy or robot-assisted laparoscopic prostatectomy at a single institution from 2008 to 2013 by one of four surgeons. Patient characteristics were compared using t-tests, rank sum or χ(2) -tests as appropriate. The association between positive end-expiratory pressure and estimated blood loss was tested using linear regression. Patients were classified into high (≥4 cmH2 O) and low (≤1 cmH2 O) positive-end expiratory pressure groups. Estimated blood loss in radical retropubic prostatectomy was higher in the high positive end-expiratory pressure group (1000 mL vs 800 mL, P = 0.042). Estimated blood loss in robot-assisted laparoscopic prostatectomy was lower in the high positive end-expiratory pressure group (150 mL vs 250 mL, P = 0.015). After adjusting for other factors known to influence blood loss, a 5-cmH2 O increase in positive end-expiratory pressure was associated with a 34.9% increase in estimated blood loss (P = 0.030) for radical retropubic prostatectomy, and a 33.0% decrease for robot-assisted laparoscopic prostatectomy (P = 0.038). In radical retropubic prostatectomy, high positive end-expiratory pressure was associated with higher estimated blood loss, and the benefits of positive end-expiratory pressure should be weighed against the risk of increased estimated blood loss. In robot-assisted laparoscopic prostatectomy, high positive end-expiratory pressure was associated with lower estimated blood loss, and might have more than just pulmonary benefits. © 2016 The Japanese Urological Association.

The best technique of radical prostatectomy--open retropubic versus robot-assisted surgery--is a subject of controversy. Between January 1st, 2007 and December 31st, 2011, 2,177 men underwent radical prostatectomy at our department. 252 (12%) cases were laparoscopic robot-assisted, the remainder open retropubic procedures. In Germany, certified prostate cancer centers are required to collect urinary tract-related outcome data after radical prostatectomy using the International Consultation of Incontinence Questionnaire Male Lower Urinary Tract Symptoms. The questionnaire data were used to compare both surgical approaches concerning the urinary tract-related outcome 1, 2 and 3 years postoperatively. Neither the voiding score nor the incontinence score or the bother scale sum differed between the two cohorts at any of the measurement times. Concerning continence recovery, in this series, there were no detectable differences between robot-assisted and open radical prostatectomy. Copyright © 2012 S. Karger AG, Basel.

We herein review our experience with endoscopic extraperitoneal radical prostatectomy (EERPE) as a first line therapy for localized prostate cancer. A series of 1,300 patients underwent EERPE ("wide excision", standard nervesparing technique (nsEERPE), or intrafascial nsEERPE). The mean age of the patients was 63.3 years. Preoperative PSA mean value was 10.1 ng/ml. A total of 415 patients had undergone previous surgical procedure in the lower abdomen (n = 336) and prior surgery of the prostate (n = 79), respectively. The EERPE was employed in all cases without any specific selection criteria. Mean operative time was 153 (50-320) min. including lymphadenectomy with no conversion to open surgery. Seven intraoperative, 91 early and 4 late complications occurred. The transfusion rate was 0.9%. Positive surgical margins were found in 83 patients with pT2 stage (9.8%) and in 154 patients in pT3 stage (34.3%). The mean catheterization time was 6.2 days. The 12 month follow up indicated continence rate of 91.9% and potency rates of 34% in the unilateral nerve sparing group and 69.8% in the bilateral group. In the intrafascial nsEERPE group potency rates were 33.3% (unilateral) and 79.1% (bilateral) after 12 months. Postoperative positive surgical margins rate were 6.1% for pT2 and 20% for pT3 and the complications rate 4%. The results of this large series of 1,300 patients are promising. The recently introduced intrafascial nsEERPE further ameliorates the outcome of the procedure.

To demonstrate a novel frozen section analysis technique during robot assisted radical prostatectomy with 2 distinct advantages: evaluation of the entire circumference and easier reconstruction for whole mount evaluation. Istanbul Preserve was performed on patients who underwent robotic prostatectomy with nerve sparing between 10/2014 and 7/2016. Gland was sectioned at 3-4mm intervals from apex to bladder neck. Entire tissue representing margins (except for the most anterior portion) was circumferentially excised and microscopically analyzed. In margin positivity, approach was individualized based on extent of positive margin and Gleason pattern. A matched cohort was established for comparison. Retrospective analysis of a prospectively maintained database was performed. Impact of FSA on PSM rate was primarily assessed. Data on 170 patients was analyzed. Positive surgical margin was reported in 56(33%) on frozen section. Neurovascular bundle was partially or totally resected in 79% and 18%. Conversion of positive margin to negative was achieved in 85%. Overall positive margin rate decreased from 22.5% to 7.5%. Nerve sparing increased from 87% to 93%. Location of positive margin at frozen was at the neurovascular bundle area in 39%; thus Istanbul Preserve detected 61% additional margin positivity compared to other techniques. Reconstruction for whole mount was easy. Istanbul Preserve is a novel technique for intraoperative FSA during RARP allowing for microscopic examination of the entire prostate for margin status and easy re-construction for whole mount examination. It guarantees safer margins together with increased rate of nerve sparing. Copyright © 2017 Elsevier Inc. All rights reserved.

Obesity is associated with poorly differentiated and advanced prostate cancer and increased mortality. In preclinical models, caloric restriction delays prostate cancer progression and prolongs survival. We sought to determine if weight loss (WL) in men with prostate cancer prior to radical prostatectomy affects tumor apoptosis and proliferation, and if WL effects other metabolic biomarkers. In this Phase II prospective trial, overweight and obese men scheduled for radical prostatectomy were randomized to a 5-8 week WL program consisting of standard structured energy-restricted meal plans (1200-1500 Kcal/day) and physical activity or to a control group. The primary endpoint was apoptotic index in the radical prostatectomy malignant epithelium. Secondary endpoints were proliferation (Ki67) in the radical prostatectomy tissue, body weight, body mass index (BMI), waist to hip ratio, body composition, and serum PSA, insulin, triglyceride, cholesterol, testosterone, estradiol, leptin, adiponectin, interleukin 6, interleukin 8, insulin-like growth factor 1, and IGF binding protein 1. In total 23 patients were randomized to the WL intervention and 21 patients to the control group. Subjects in the intervention group had significantly more weight loss (WL:-3.7 ± 0.5 kg; Control:-1.6 ± 0.5 kg; p = 0.007) than the control group and total fat mass was significantly reduced (WL:-2.1 ± 0.4; Control: 0.1 ± 0.3; p = 0.015). There was no significant difference in apoptotic or proliferation index between the groups. Among the other biomarkers, triglyceride, and insulin levels were significantly decreased in the WL compared with the control group. In summary, this short-term WL program prior to radical prostatectomy resulted in significantly more WL in the intervention vs. the control group and was accompanied by significant reductions in body fat mass, circulating triglycerides, and insulin. However, no significant changes were observed in malignant

There are competing hypotheses about the etiology of post prostatectomy incontinence (PPI). The purpose of this study was to determine the anatomical and functional differences between men with and without PPI. Case-control study of continent and incontinent men after radical prostatectomy who underwent functional and anatomic studies with urodynamics and 3.0 Tesla MRI. All men were at least 12 months post prostatectomy and none had a history of pelvic radiation or any prior surgery for incontinence. Baseline demographics, surgical approach, and pathology were similar between incontinent (cases) (n = 14) and continent (controls) (n = 12) men. Among the cases, the average 24 hr pad weight was 400.0 ± 176.9 g with a mean of 2.4 ± 0.7 pads per day. Urethral pressure profiles at rest did not significantly differ between groups; however, with a Kegel maneuver the rise in urethral pressure was 2.6 fold higher in controls. On MRI, the urethral length was 31-35% shorter and the bladder neck was 28.9° more funneled in cases. There were no differences in levator ani muscle size between groups. There was distortion of the sphincter area in 85.7% of cases and in 16.7% of controls (P = 0.001). Men with PPI were not able to increase urethral pressure with a Kegel maneuver despite similar resting urethral pressure profiles. Additionally, incontinent men had shorter urethras and were more likely to have distortion of the sphincter area. All suggesting that the sphincter in men with PPI is both diminutive and poorly functional. © 2014 Wiley Periodicals, Inc.

Aims There are competing hypotheses about the etiology of post prostatectomy incontinence (PPI).The purpose of this study was to determine the anatomical and functional differences between men with and without PPI. Methods Case control study of continent and incontinent men after radical prostatectomy who underwent functional and anatomic studies with urodynamics and 3.0 Tesla MRI. All men were at least 12 months post prostatectomy and none had a history of pelvic radiation or any prior surgery for incontinence. Results Baseline demographics, surgical approach and pathology were similar between incontinent (cases) (n=14) and continent (controls) (n=12) men. Among the cases, the average 24 hour pad weight was 400.0 ±176.9 grams with a mean of 2.4 ±0.7 pads per day. Urethral pressure profiles at rest did not significantly differ between groups; however with a Kegel maneuver the rise in urethral pressure was 2.6 fold higher in controls. On MRI, the urethral length was 31–35% shorter and the bladder neck was 28.9 degrees more funneled in cases. There were no differences in levator ani muscle size between groups. There was distortion of the sphincter area in 85.7% of cases and in 16.7% of controls (p=0.001). Conclusions Men with PPI were not able to increase urethral pressure with a Kegel maneuver despite similar resting urethral pressure profiles. Additionally, incontinent men had shorter urethras and were more likely to have distortion of the sphincter area. All suggesting that the sphincter in men with PPI is both diminutive and poorly functional. PMID:24752967

The use of robot-assisted radical prostatectomy has increased rapidly despite the absence of randomized, controlled trials showing the superiority of this approach. While recent studies suggest an advantage for perioperative complication rates, they fail to account for the volume-outcome relationship. We compared perioperative outcomes after robot-assisted and open radical prostatectomy, while considering the impact of this established relationship. Using the NIS (Nationwide Inpatient Sample), we abstracted data on patients treated with radical prostatectomy in 2009. Univariable and multivariable logistic regression analyses were done to compare the rates of blood transfusion, intraoperative and postoperative complications, prolonged length of stay, increased hospital charges and mortality between robot-assisted and open radical prostatectomy overall and across volume quartiles. An estimated 77,616 men underwent radical prostatectomy, including a robot-assisted and an open procedure in 63.9% and 36.1%, respectively. Low volume centers averaged 26.2 robot-assisted and 5.2 open cases, while very high volume centers averaged 578.8 robot-assisted and 150.2 open cases. Overall, patients treated with the robot-assisted procedure experienced a lower rate of adverse outcomes than those treated with the open procedure for all measured categories. Across equivalent volume quartiles robot-assisted radical prostatectomy outcomes were generally favorable. However, the open procedure at high volume centers resulted in a lower postoperative complication rate (OR 0.59, 95% CI 0.46-0.75), elevated hospital charges (OR 0.75, 95% CI 0.64-0.87) and a comparable blood transfusion rate (OR 1.38, 95% CI 0.93-2.02) relative to the robot-assisted procedure at low volume centers. Regionalization has occurred to a greater extent for robot-assisted than for open radical prostatectomy with an associated benefit in overall outcomes. Nonetheless, low volume institutions experienced inferior

Statins have been linked with improved prostate cancer survival and lower risk of recurrence in men treated with radiation therapy. However, the association is unclear for surgically-treated men. We studied the risk of prostate cancer recurrence and death by statin usage after radical prostatectomy in a cohort of prostate cancer patients treated with radical prostatectomy. A cohort of 1,314 men who underwent curative-intent radical prostatectomy at the Tampere University Hospital, Tampere, Finland during 1995-2009 were linked to national prescription database to obtain detailed information on statin purchases. The risk of PSA recurrence and death (overall and prostate cancer-specific) by statin use before and after the surgery were evaluated using Cox regression with model adjustment for tumor characteristics, total cholesterol and simultaneous use of antidiabetic and antihypertensive drugs. Tissue expression of putative prognostic markers were measured from a subgroup of 323 men. During the median follow-up of 8.6 years after surgery 484 men recurred, while 244 men died (32 due to prostate cancer). In general statin use before or after prostatectomy was not associated with risk of disease recurrence or death. Tissue expression of Ki-67 and ERG modified the association between statin use and risk of disease recurrence; the risk estimates were lower in men with Ki-67 expression above the median (P for interaction 0.001 and 0.004 for statin use before and after prostatectomy, respectively) and no ERG expression in the tumor tissue (P for interaction 0.006 and 0.011). Statin use generally did not affect prostate cancer prognosis after prostatectomy. The effect on disease recurrence may depend on tumor properties, such as proliferation activity. Thus possible future prospective studies should recognize and enroll subgroups of prostate cancer patients most likely to benefit from statins. © 2015 Wiley Periodicals, Inc.

Radical prostatectomy has recently been shown to prolong cancer-specific survival compared to watchful waiting in patients with localized prostate cancer. Most patients who seek medical advice for this disease are treated in hospitals in which the operation is performed relatively infrequently. The aim of this study is to report the oncological outcome at intermediate- to long-term follow-up after radical prostatectomy performed in a community hospital. A total of 148 patients underwent radical prostatectomy at Ryhov County Hospital between 1985 and 1997. Patients without T3 tumours, prostate-specific antigen (PSA) >10 ng/ml or poorly differentiated tumours were judged to be in a low-risk group, those with one risk factor to be in an intermediate group and those with two or more factors to be in a high-risk group. The projected biochemical disease free- and cancer-specific survival rates were compared between these risk groups. Median follow-up was 96 months for surviving patients. Patients in the low- and intermediate risk groups had equal 10-year PSA-free survival rates of 68.8%, while that in the high-risk group was only 19.3% (9-year data). Corresponding cancer-specific survival rates were 93% and 84%, respectively. The oncological outcome seems comparable to that reported in the literature, even when the operation is performed in a low-volume community-based setting.

The aim of this study is to analyze the current literature on single port radical prostatectomy (LESS-RP). Single port radical prostatectomy laparoendoscopic (LESS-RP) has established itself as a challenge for urological community, starting with the proposal of different approaches: extraperitoneal, transperitoneal and transvesical, initially described for laparoscopy and then laparoscopy robot-assisted. In order to improve the LESS-RP, new instruments, optical devices, trocars and retraction mechanisms have been developed. Advantages and disadvantages of LESS-RP are controversial, while some claim that it is a non-trustable approach, regarding the low cases number and technical difficulties, others acclaim that despite this facts some advantages have been shown and that previous described difficulties are being overcome, proving this is novel proposal of robotics platform, the Da Vinci SP, integrating the system into "Y". The LESS-RP approach gives us a new horizon and opens the door for rapid standardization of this technique. The few studies and short series available can be result of a low interest in the application of LESS-RP in prostate, probably because of the technical complexity that it requires. The new robotic platform, the da Vinci SP, shows that it is clear that the long awaited evolution of robotic technologies for laparoscopy has begun, and we must not lose this momentum.

The robotic assisted radical prostatectomy (RARP) has become the most common operative choice for localized prostate cancer. At our institution, we have also seen a substantial increase in the proportion of RARP. Possible patient factors may include marketing, increased Internet usage by patients, and patient-to-patient communication. We surveyed urologists from the central United States to determine possible surgeon factors for the popularity of the RARP. We mailed a survey to all urologists in the South Central Section of the American Urological Association. After demographic information was obtained, participants were asked to choose an operation for themselves based on two prostate cancer scenarios; low risk and high risk. For the low risk prostate cancer scenario, 54.3% chose RARP while 32.9% chose a radical retropubic prostatectomy (RRP). In the high risk scenario, 32.3% chose a RARP while 58.8% chose the RRP. The top reasons for choosing robotics included decreased blood loss, better pain control, and visualization of the apex. The most popular reasons for an open operation included improved lymph node dissection, better tactile sensation, and easier operation for the surgeon. The two most important factors for choosing a particular operation were cancer control and the urologist performing the operation. Also, urologists favored the operative choice in which he or she performed. Robotic assisted radical prostatectomy has become the favored operative approach for low risk prostate cancer. However, many urologists still feel an oncologic difference may exist between open and robotic surgery as evidenced by more urologists favoring an open approach for high risk prostate cancer.

Knowledge of the psychological distress of long- and very long-term (>10 years) prostate cancer (PC) survivors is limited. This study intended to examine the parameters influencing anxiety related to prostate-specific antigen (PSA) and PC in long-term survivors after radical prostatectomy. We surveyed 4719 PC survivors from the German multicenter prospective database "Familial Prostate Cancer." We evaluated the association of PC-related anxiety (MAX-PC) with sociodemographic characteristics, family history of PC, global health status/quality of life (EORTC QLQ-C30), depression and anxiety (PHQ-2; GAD-2), latest PSA level, time since radical prostatectomy, and current therapy. The survey participants' mean age was 75.2 years (SD = 6.5). Median follow-up was 11.5 years, and 19.5% of participants had survived more than 15 years since the initial treatment. The final regression analysis found that younger age, lower global health status/quality of life, higher depression and anxiety scores, higher latest PSA level, and shorter time since radical prostatectomy predicted increased PSA-related anxiety and PC anxiety. Familial PC was predictive only of PSA anxiety (all p < 0.05). The final model explained 12% of the variance for PSA anxiety and 24% for PC anxiety. PC-related anxiety remained relevant many years after prostatectomy and was influenced by younger age, psychological status, rising PSA level, and shorter time since initial treatment. Survivors with these characteristics are at increased risk of PC-related anxieties, which should be considered by the treating physician during follow-up.

Acute normovolemic haemodilution for management of blood loss during radical prostatectomy.

PubMed

Gal, R

2008-01-01

The reduction of the risks of anemia and allogeneic transfusion is one the basic parts of the anaesthesia management in large urological procedures. We used acute normovolemic haemodilution (ANH) as a technique of autologous blood procurement in patients scheduled for radical prostatectomy. 15 patients undergoing radical prostatectomy were enrolled in our study. After starting general anaesthesia the left radial artery line was placed for invasive blood pressure monitoring and withdrawing blood for ANH. The restoration of circulated volume was instituted by infusion of crystalloids and colloids. Reinfusion of gained blood was started after transfusion trigger was reached (Hct 0.25). The average total blood loss was in amount of 2393 +/- 238 (ml), autologous blood was infused in amount of 1919 +/- 220 (ml). The preoperative haematocrit was 41 +/- 3, after ANH 29 +/-2 and 31 +/- 3 (%) postoperatively. One unit of allogeneic blood was transfused in 2 patients only. All patients were hemodynamically stable during the entire surgery, with minimal systolic blood pressure of 100 mmHg and were extubated in the operation room with no complications. This study demonstrated the effectiveness and safety of ANH as a method for avoiding the allogeneic blood transfusion in patients undergoing radical prostatectomy (Tab. 1, Ref. 10).

Transperitoneal versus extraperitoneal robotic-assisted radical prostatectomy: which one?

PubMed

Atug, F; Thomas, R

2007-06-01

As robotic surgery has proliferated, both in its availability as well as in its popularity, there are certainly several unresolved matters in the burgeoning field of robotic radical prostatectomy. Matters that are commonly discussed at forums relating to robotic prostatectomy include training, proctoring, overcoming the learning curve, positive surgical margins, quality of life issues, etc. Among the approaches available for robotic radical prostatectomy are the trans-peritoneal (TP) and the extraperitoneal (EP) approaches. Although use of the TP approach vastly outnumbers the EP approach by a wide margin, one must not discount the need for learning the EP approach, especially in patients who could greatly benefit from this approach. The obese, those who have had intraperitoneal procedures in the past, those with ostomies (colostomy, ileostomy) should be considered candidates for the EP approach. For the beginner, it is recommended that familiarizing oneself with the TP approach may be the quickest way to get proficient with use of the robot and for getting over the learning curve, which varies from surgeon to surgeon. Once comfortable with the TP approach, one should consider the application of the EP access, when indicated. One distinct disadvantage of the EP approach is the limited space available for robotic movements. This is why one would prefer getting experience in the TP before forging into the EP approach. Certainly, adequate balloon dissection of the retroperitoneal space above the bladder is critical, as well as additional dissection with the camera in place. Another criticism of the EP approach is the fact that one may not have enough space or ability to perform a complete pelvic lymph node dissection. However, in experienced hands, one is able to do a very comparable job. Though the TP approach would continue to be the premium approach for robotic and laparoscopic radical prostatectomy, one should familiarize oneself with the EP approach since this

Decision regret (DR) may occur when a patient believes their outcome would have been better if they had decided differently about their management. Although some studies investigate DR after treatment for localised prostate cancer, none report DR in patients undergoing surgery and post-prostatectomy radiotherapy. We evaluated DR in this group of patients overall, and for specific components of therapy. We surveyed 83 patients, with minimum 5 years follow-up, treated with radical prostatectomy (RP) and post-prostatectomy image-guided intensity-modulated radiotherapy (IG-IMRT) to 64-66 Gy following www.EviQ.org.au protocols. A validated questionnaire identified DR if men either indicated that they would have been better off had they chosen another treatment, or they wished they could change their mind about treatment. There was an 85.5% response rate, with median follow-up post-IMRT 78 months. Adjuvant IG-IMRT was used in 28% of patients, salvage in 72% and ADT in 48%. A total of 70% of patients remained disease-free. Overall, 16.9% of patients expressed DR for treatment, with fourfold more regret for the RP component of treatment compared to radiotherapy (16.9% vs 4.2%, P = 0.01). DR for androgen deprivation was 14.3%. Patients were regretful of surgery due to toxicity, not being adequately informed about radiotherapy as an alternative, positive margins and surgery costs (83%, 33%, 25% and 8% of regretful patients respectively). Toxicity caused DR in the three radiotherapy-regretful and four ADT-regretful patients. Patients were twice as regretful overall, and of surgery, for salvage vs adjuvant approaches (both 19.6% vs 10.0%). Decision regret after RP and post-prostatectomy IG-IMRT is uncommon, although patients regret RP more than post-operative IG-IMRT. This should reassure urologists referring patients for post-prostatectomy IG-IMRT, particularly in the immediate adjuvant setting. Other implications include appropriate patient selection for RP (and

In this study, we document trends in radical prostatectomy (RP) employment in Germany during the period 2005-2012 and compare the morbidity of open (ORP), laparoscopic and robotic-assisted RP based on nationwide administrative data of Allgemeine Ortskrankenkassen (AOK) German local healthcare funds. Administrative claims data of all AOK patients subjected to RP during 2005-2012 (57,156 cases) were used to evaluate the employment of minimally invasive RP (MIRP) procedures, pelvic lymph node dissection (PLND) and nerve-sparing approaches during this period. In addition, data from the most recent three-year period of our dataset (2010-2012) were used to compare the morbidity among the different surgical approaches. Study end points comprised 30-day mortality, 30-day transfusion, 1-year reintervention and 30-day adverse events, as well as 1-year overall complications. A 20 % reduction in RP utilization from 2007 to 2012 was documented. ORP remained the predominant RP approach in Germany. MIRP approaches carried a lower risk of 30-day transfusions, 1-year reinterventions and 1-year overall complications than ORP when adjusting for confounding factors. PLND was associated with an increased risk of complications, while age in the highest quintile and the presence of comorbidities were independent risk factors for morbidity and mortality. Lack of pathological data was the main limitation of the study. RP utilization in Germany is dropping, but the use of MIRP has risen steadily during the years 2005-2012, which is expected to have a positive impact on the morbidity of the operation.

Limited data are available regarding the impact of the type of healthcare delivery system on technology diffusion and associated clinical outcomes. We assessed the adoption of minimally invasive radical prostatectomy (MIRP), a recent clinical innovation, and whether this adoption altered surgical morbidity for prostate cancer surgery. Retrospective review of administrative data from TRICARE, the healthcare program of the United States Military Health System. Surgery occurred at military hospitals, supported by federal appropriations, or civilian hospitals, supported by hospital revenue. We evaluated TRICARE beneficiaries with prostate cancer (International Classification of Disease, 9th Revision, Clinical Modification [ICD-9-CM] code: 185) who received a radical prostatectomy (60.5) between 2005 and 2009. MIRP was identified based on minimally invasive surgery codes (54.21, 17.42). We assessed yearly MIRP utilization, 30-day postoperative complications (Clavien classification system), length of stay, blood transfusion, and long-term urinary incontinence and erectile dysfunction. A total of 3366 men underwent radical prostatectomy at military hospitals compared with 1716 at civilian hospitals, with minimal clinic-demographic differences. MIRP adoption was 30% greater at civilian hospitals. There were fewer blood transfusions (odds ratio, 0.44; P <.0001) and shorter lengths of stay (incidence risk ratio, 0.85; P <.0001) among civilian hospitals, while 30-day postoperative complications, as well as long-term urinary incontinence and erectile dysfunction rates, were comparable. Compared with military hospitals, civilian hospitals had a greater MIRP adoption during this timeframe, but had comparable surgical morbidity.

Does penile rehabilitation have a role in the treatment of erectile dysfunction following radical prostatectomy?

2017-01-01

In men undergoing radical treatment for prostate cancer, erectile function is one of the most important health-related quality-of-life outcomes influencing patient choice in treatment. Penile rehabilitation has emerged as a therapeutic measure to prevent erectile dysfunction and expedite return of erectile function after radical prostatectomy. Penile rehabilitation involves a program designed to increase the likelihood of return to baseline-level erectile function, as opposed to treatment, which implies the therapeutic treatment of symptoms, a key component of post–radical prostatectomy management. Several pathological theories form the basis for rehabilitation, and a plethora of treatments are currently in widespread use. However, whilst there is some evidence supporting the concept of penile rehabilitation from animal studies, randomised controlled trials are contradictory in outcomes. Similarly, urological guidelines are conflicted in terms of recommendations. Furthermore, it is clear that in spite of the lack of evidence for the role of penile rehabilitation, many urologists continue to employ some form of rehabilitation in their patients after radical prostatectomy. This is a significant burden to health resources in public-funded health economies, and no effective cost-benefit analysis has been undertaken to support this practice. Thus, further research is warranted to provide both scientific and clinical evidence for this contemporary practice and the development of preventative strategies in treating erectile dysfunction after radical prostatectomy.

To develop a nomogram based on postoperative factors and prostate-specific antigen levels to predict the non-biochemical recurrence rate after radical prostatectomy ina Japanese cohort. A total of 606 Japanese patients with T1-3N0M0 prostate cancer who underwent radical prostatectomy and pelvic lymph node dissection at Tokyo Medical University hospital from 2000 to 2010 were studied. A nomogram was constructed based on Cox hazard regression analysis evaluating the prognostic significance of serum prostate-specific antigen and pathological factors in the radical prostatectomy specimens. The discriminating ability of the nomogram was assessed by the concordance index (C-index), and the predicted and actual outcomes were compared with a bootstrapped calibration plot. With a mean follow up of 60.0 months, a total of 187 patients (30.9%) experienced biochemical recurrence, with a 5-year non-biochemical recurrence rate of 72.3%. Based on a Cox hazard regression model, a nomogram was constructed to predict non-biochemical recurrence using serum prostate-specific antigen level and pathological features in radical prostatectomy specimens. The concordance index was 0.77, and the calibration plots appeared to be accurate. The postoperative nomogram described here can provide valuable information regarding the need for adjuvant/salvage radiation or hormonal therapy in patients after radical prostatectomy.

Routine pelvic drainage not required after open or robotic radical prostatectomy.

To determine whether radical prostatectomy requires urinary drainage. All patients with clinically localized prostate cancer had complete clinical and pathologic information recorded prospectively in a database. The criteria for omission of pelvic drainage were successful bladder neck preservation; urethrovesical anastomosis performed using 6 interrupted sutures in open cases or 12 continuous sutures in robotic cases; and a watertight urethrovesical anastomosis on irrigation. Most patients were discharged on the first or second postoperative day. The catheters were removed routinely on postoperative day 9. A pelvic drain was not placed in 78% of 325 consecutive patients. A drain was omitted in 73% of 225 open cases and 90% of 100 robotic cases. The recovery of continence and the complication rates were similar between the two groups with and without pelvic drainage. Complications occurred in 11% of the group with pelvic drainage and 6% in the group without pelvic drainage. In the past 2 years, 17 of 126 patients required pelvic drainage. The frequency of complications in robotic versus open procedures was similar (chi-square test, P >0.05). Pelvic drainage may be omitted after radical prostatectomy when the urethrovesical anastomosis is performed well. Drainage omission could contribute to shortened hospital stays and reduced costs, without added complications. These benefits can be extended safely to patients undergoing open or robotic radical prostatectomy.

Therapy (case series). 4. To evaluate factors that affect compliance in men who enroll in a phosphodiesterase type 5 inhibitor (PDE5I) protocol after nerve-sparing robot-assisted prostatectomy (RAP), and report on short-term outcomes, as PDE5Is may help restore erectile function after RAP and patient adherence to the regimen is a factor that potentially can affect outcome. We prospectively followed 77 men who had nerve-sparing RAP and enrolled in a postoperative penile rehabilitation protocol. The men received either sildenafil citrate or tadalafil three times weekly. The minimum follow-up was 8 weeks. Potency was defined as erection adequate for penetration and complete intercourse. Compliance was defined as men adhering to the regimen for > or =2 months. The mean age of the cohort was 57.8 years and the median follow-up was 8 months. In all, 32% of the men discontinued the therapy <2 months after RAP and were deemed noncompliant with an additional 39% discontinuing therapy by 6 months, with the high cost of medication being the primary reason (65%). Long-term compliance and preoperative erectile dysfunction were independent predictors of potency return after adjusting for age and nerve sparing. The high cost of medication remains a significant barrier to maintaining therapy. Noncompliance to PDE5I therapy in a tertiary care centre was much higher than reported in clinical trial settings. With longer-term follow-up, we need to further define the factors that improve overall recovery of sexual function after RAP.

Low-intensity extracorporeal shock wave therapy (LI-ESWT) is a novel treatment for erectile dysfunction (ED). Its ability to improve erectile function has been shown in patients with vasculogenic ED by many randomized-controlled trials against sham procedures. However, the role of LI-ESWT in ED caused by radical prostatectomy (RP) is still questionable because this type of ED was excluded from nearly all clinical studies; it has been investigated in only a few small single-arm trials. This review summarizes preclinical studies on mechanisms of action of LI-ESWT for ED and neurological diseases to explore the potential of this treatment for nerve-impaired ED after RP.

To study a novel penile reinnervation technique using four sural nerve grafts and end-to-side neurorraphies connecting bilaterally the femoral nerve and the cavernous corpus and the femoral nerve and the dorsal penile nerves. Ten patients (mean [± sd; range] age 60.3 [± 4.8; 54-68] years), who had undergone radical prostatectomy (RP) at least 2 years previously, underwent penile reinnervation in the present study. Four patients had undergone radiotherapy after RP. All patients reported satisfactory sexual activity prior to RP. The surgery involved bridging of the femoral nerve to the dorsal nerve of the penis and the inner part of the corpus cavernosum with sural nerve grafts and end-to-side neurorraphies. Patients were evaluated using the International Index of Erectile Function (IIEF) questionnaire and pharmaco-penile Doppler ultrasonography (PPDU) preoperatively and at 6, 12 and 18 months postoperatively, and using a Clinical Evolution of Erectile Function (CEEF) questionnaire, administered after 36 months. The IIEF scores showed improvements with regard to erectile dysfunction (ED), satisfaction with intercourse and general satisfaction. Evaluation of PPDU velocities did not reveal any difference between the right and left sides or among the different time points. The introduction of nerve grafts neither caused fibrosis of the corpus cavernosum, nor reduced penile vascular flow. CEEF results showed that sexual intercourse began after a mean of 13.7 months with frequency of sexual intercourse varying from once daily to once monthly. Acute complications were minimal. The study was limited by the small number of cases. A total of 60% of patients were able to achieve full penetration, on average, 13 months after reinnervation surgery. Patients previously submitted to radiotherapy had slower return of erectile function. We conclude that penile reinnervation surgery is a viable technique, with effective results, and could offer a new treatment method for ED after

To describe our pelvic lymphadenectomy (PLND) technique during robot-assisted radical prostatectomy and to evaluate the nodal yield and perioperative outcomes. PLND is commonly performed with radical prostatectomy for localized prostate cancer. Because of the limitations of the robotic arm pitch in accessing the pelvic sidewall and undersurface of the iliac bifurcation, uro-oncologists have questioned the adequacy of robotic PLND. PLND was routinely performed on men with higher risk preoperative prostate cancer parameters (ie, prostrate-specific antigen >10 ng/mL, primary Gleason score > or =4, or clinical Stage T2b or greater). The outcomes of robot-assisted radical prostatectomy with bilateral, standard template PLND (group 1; n = 296 [26%]) were compared with those of a cohort of 859 robot-assisted radical prostatectomy patients (74%) without PLND (group 2). We also compared these data with those from a single-surgeon experience of open, standard-template PLND for retropubic radical prostatectomy. The mean number of lymph nodes removed was 12.5 (interquartile range 7-16). The mean operative time (224 vs 216 minutes; P = .09), estimated blood loss (206 vs 229 mL; P = .14), and hospital stay (1.32 vs 1.24 days; P = .46) were comparable between the 2 groups. The rate of intraoperative complications (1% vs 1.5%; P = .2), overall postoperative complications (9% vs 7%; P = .8), and lymphocele formation (2% vs 0%; P = .9) were not significantly different. The review of our open series and the historically published open standard-template PLND series revealed a mean yield of 15 and a range of 6.7-15 lymph nodes removed, respectively. Our data support the feasibility and low complication rate of robotic standard-template PLND with lymph node yields comparable to those with open PLND. Considering the low morbidity of PLND in experienced hands, coupled with the potential of preoperative undergrading and understaging and the therapeutic benefit to patients with

Purpose: To evaluate outcomes among a matched cohort of prostate cancer patients treated with radical retropubic prostatectomy (RRP) and robot assisted radical prostatectomy (RARP). Materials and methods: Between 2002 and 2005, 294 patients underwent RARP at our institution. Comparison RRP patients were matched 2:1 for surgical year, age, PSA, clinical stage, and biopsy grade (n=588). Outcomes among groups were compared. From an oncologic standpoint, pathologic features among groups were assessed and Kaplan-Meier estimates of PSA recurrence free survival were compared. Results: Overall margin positivity was not significantly different between groups (RARP, 15.6%, RRP, 17%), yet risk of apical margin was significantly less with RARP. RARP was associated with significantly shorter hospitalization (p<0.01) and lower incidence of blood transfusion (p < 0.01). Early complications were higher in the RARP group (16% vs 10%, p<0.01). Among late complications, risk of bladder neck contracture was lower with RARP (1.2%, p=0.02). Adjuvant hormonal therapy was significantly higher in the RRP group (6.6% p<0.01). Continence at 1 year among groups was equivalent (p=0.15). Potency at 1 year was better among RARP patients (p=0.02). At a median followup of 1.3 years, PSA recurrence free estimates were not significantly different (92% vs 92%, p=0.69). Conclusions: Early complications were higher in this RARP group, but this experience includes cases performed in the learning curve. Oncologic, quality of life, and functional data in this study revealed encouraging results for RARP when compared to RRP.

Length and location of positive surgical margins are independent predictors of biochemical recurrence after open radical prostatectomy. We assessed their impact on biochemical recurrence in a large robotic prostatectomy series. Data were collected prospectively from 1,398 men undergoing robotic radical prostatectomy for clinically localized prostate cancer from 2003 to 2008 at a single institution. The associations of preoperative prostate specific antigen, pathological Gleason score, pathological stage and positive surgical margin parameters (location, length and focality) with biochemical recurrence rate were evaluated. Margin status and length were measured by a single uropathologist. Biochemical recurrence was defined as serum prostate specific antigen greater than 0.1 ng/ml on 2 consecutive tests. Cox regression models were constructed to evaluate predictors of biochemical recurrence. Of 1,398 consecutive patients who underwent robotic prostatectomy positive margins were present in 243 (17%) (11% of pathological T2 and 41% of T3). Preoperative prostate specific antigen, pathological stage, Gleason score, margin status, and margin length as a continuous and categorical variable (less than 1, 1 to 3, more than 3 mm) were independent predictors of biochemical recurrence. Patients with negative margins and those with a positive margin less than 1 mm had similar rates of biochemical recurrence (log rank test p = 0.18). Surgical margin location was not independently associated with biochemical recurrence. Margin status and length are independent predictors of biochemical recurrence following robotic radical prostatectomy. Although longer followup and validation studies are necessary for confirmation, patients with a positive margin less than 1 mm appear to have similar recurrence rates as those with negative margins.

Abdominal straining associated with voiding dysfunction or constipation has traditionally been associated with the development of abdominal wall hernias. Thus, classic general surgery dictum recommends that any coexistent bladder outlet obstruction should be addressed by the urologist before patients undergo surgical repair of a hernia. While organ-confined prostate cancer is usually not associated with the development of lower urinary tract symptoms, a modest proportion of patients treated with radical prostatectomy may have coexisting benign prostatic hyperplasia with elevated symptom scores and hernias may be incidentally detected at the time of surgery. Furthermore, dissection of the space of Retzius during retropubic or minimally invasive prostatectomy may result exposure of abdominal wall defects which may have been present, but asymptomatic if plugged with preperitoneal fat. Herein we examine the literature regarding the incidence of postoperative inguinal hernias after prostatectomy, review potential risk factors which could aid in preoperative patient identification, and discuss the published experience regarding concurrent hernia repair at the time of open or minimally invasive radical prostatectomy.

Indium-111 radioimmunoscintigraphy (RIS) has an increasing role in the treatment of prostate cancer and is most commonly performed at this disease site using labeled monoclonal antibody against prostate-specific membrane antigen. There are many limitations of RIS, including low spatial resolution, low diagnostic yield and limited availability. Despite these limitations, the efficacy of RIS has been demonstrated in many clinical studies, including multi-institutional investigations. The highest sensitivity and specificity of RIS appears to be in the post-radical retropubic prostatectomy (post-RRP) setting. RIS has recently been explored for its role in clinical radiotherapy decision-making, and was found to have a significant impact in selecting patients for radiotherapy and for the general radiotherapy treatment volume definition. RIS has also recently been explored for its role in radiotherapy planning and was found to impact clinical target volume design. However, manual editing of the RIS volume is still necessary when projected into the radiotherapy-planning scan, as there is often overlap in the RIS-defined uptake regions with normal structures (rectum, bladder and symphysis bone marrow). The impact of RIS on biochemical control has been explored, with studies in this area yielding conflicting results. It appears that the maximum impact of RIS is possible when areas of labeled antibody uptake regions are co-registered with the radiotherapy-planning computed tomography scan.The larger RIS-guided target volumes do not appear to be prohibitive in increasing radiotherapy-related toxicity. Future directions of the use of RIS for post-RRP prostate cancer are discussed. PMID:17607048

To investigate if pathologic biopsy reevaluation and implementation of immunohistochemical biomarkers could improve prediction of radical prostatectomy outcome in men initially on active surveillance. Biopsy specimens from diagnosis until switching to radical prostatectomy in men initially on active surveillance in the Dutch part of the Prostate cancer Research International Active Surveillance (PRIAS) study were collected and revised by a single pathologist. Original and revised biopsy Gleason score were compared and correlated with radical prostatectomy Gleason score. Biopsy specimens were immunohistochemically stained for Ki67 and ERG. Predictive ability of clinical characteristics and biomarkers on Gleason ≥7 or ≥pT3 on radical prostatectomy was tested using logistic regression and ROC curve analysis. A total of 150 biopsies in 95 men were revised. In 13% of diagnostic or second-to-last biopsies and 20% of the last biopsies on active surveillance revision of Gleason score resulted in change of recommendation (ie, active treatment or active surveillance). Concordance with Gleason score on radical prostatectomy was however similar for both the revised and original Gleason on biopsy. Ki67 and ERG were not statistically significant predictors of Gleason ≥7 or ≥pT3 on radical prostatectomy. Although interobserver differences in pathology reporting on biopsy could result in a change of management strategy in approximately 13-20% of men on active surveillance, both pathological revision and tested biomarkers (Ki67 and ERG) did not improve prediction of outcome on radical prostatectomy. Undersampling of most aggressive tumor remains the main focus in order to increase accurate grading at time of treatment decision making. © 2017 Wiley Periodicals, Inc.

Objective To establish whether the good prognosis of Gleason score 6 (GS6) is maintained in the setting of multiple involved cores. Patients and Methods In total, 6156 men (from 1 April 2000 to 30 April 2007) with GS6 on biopsy underwent radical prostatectomy (RP) at our institution. The number of positive cores was correlated with the outcome at RP. Results More positive cores correlated with less organ-confined disease (P < 0.001), positive margins (P < 0.012), increasing RP grade (P < 0.001) and increased seminal vesicles/lymph node involvement (P = 0.012). For men with data available, the actuarial risk of being biochemically free of disease at 5 years was 93.2% when ≤6 cores were positive (812 men followed to 5 years) vs 89.1% if >6 cores were positive (41 men followed to 2 years) (P = 0.6). Although the predicted ‘cure rate’ of >75% probability of a tumour showing no evidence of biochemical recurrence at 10 years after RP was statistically different between cases with ≤6 vs >6 positive cores (P < 0.0001), the outcome in both groups was still favourable (90.5% vs 84%). Partin-like tables were generated factoring in the number of positive cores to predict organ-confined disease as a guide for urologists to perform nerve-sparing surgery. For example, with T1c disease, there was a ≥75% probability of organ-confined disease with one to three positive cores regardless of prostate-specific antigen (PSA) level, and the same probability was present with four to six positive cores and a PSA level of 0–4 ng/mL. Conclusion A low Gleason score on biopsy is a powerful prognostic finding, such that this favourable outcome is maintained even in the setting of multiple positive cores with GS6. PMID:23350787

Robotic radical prostatectomy: present and future.

The last 10 years have witnessed unprecedented evolution regarding de surgical removal of the prostate gland. Laparoscopic radical prostatectomy broke the open paradigm and started to generate great excitement and expectations. Shortly however, robot-assisted, laparoscopic - Robotic Surgery - emerged to address a fundamental pitfall of prostate laparoscopic surgery: execution reproducibility. Today, robotic assisted laparoscopic prostatectomy is the most used surgical approach to remove the prostate gland. Consistent advantages of this technique are: a shorter convalescent state, marked decrease in blood loss and in experienced hands, shorter average surgical times. Importantly it served to highlight the importance of outcomes as ultimate judge of a procedure success. The data suggest equivalency in long-term functional and oncological outcomes, while clear advantages in the short run: perioperative outcomes with patient rapid return to productive state. That said, the major challenge for robotic surgeons still remains: establish a paradigm that breaks with the tradition and prevents biased reporting due to technology and marketing enthusiasm, but rather takes a critical approach based in prospective, controlled, randomize clinical trials. If the latter objective is reached, urologic robotic surgeons will deliver counseling based on clinical evidence delivering major progress for our Urology field.

Urinary and sexual outcomes in long-term (5+ years) prostate cancer disease free survivors after radical prostatectomy

Background After long term disease free follow up (FUp) patients reconsider quality of life (QOL) outcomes. Aim of this study is assess QoL in prostate cancer patients who are disease-free at least 5 years after radical prostatectomy (RP). Methods 367 patients treated with RP for clinically localized pCa, without biochemical failure (PSA ≤ 0.2 ng/mL) at the follow up ≥ 5 years were recruited. Urinary (UF) and Sexual Function (SF), Urinary (UB) and Sexual Bother (SB) were assessed by using UCLA-PCI questionnaire. UF, UB, SF and SB were analyzed according to: treatment timing (age at time of RP, FUp duration, age at time of FUp), tumor characteristics (preoperative PSA, TNM stage, pathological Gleason score), nerve sparing (NS) procedure, and hormonal treatment (HT). We calculated the differences between 93 NS-RP without HT (group A) and 274 non-NS-RP or NS-RP with HT (group B). We evaluated the correlation between function and bother in group A according to follow-up duration. Results Time since prostatectomy had a negative effect on SF and a positive effect SB (both p < 0.001). Elderly men at follow up experienced worse UF and SF (p = 0.02 and p < 0.001) and better SB (p < 0.001). Higher stage PCa negatively affected UB, SF, and SB (all: p ≤ 0.05). NS was associated with better UB, SF and SB (all: p ≤ 0.05); conversely, HT was associated with worse UF, SF and SB (all: p ≤ 0.05). More than 8 years after prostatectomy SF of group A and B were similar. Group A subjects (NS-RP without HT) demonstrated worsening SF, but improved SB, suggesting dissociation of the correlation between SF and SB over time. Conclusion Older age at follow up and higher pathological stage were associated with worse QoL outcomes after RP. The direct correlation between UF and age at follow up, with no correlation between UF and age at time of RP suggests that other issues (i.e: vascular or neurogenic disorders), subsequent to RP, are determinant on urinary incontinence.

ABSTRACT Background Radical prostatectomy (RP) has been used as the main primary treatment for prostate cancer (PCa) for many years with excellent oncologic results. However, approximately 20-40% of those patients has failed to RP and presented biochemical recurrence (BCR). Prostatic specific antigen (PSA) has been the pivotal tool for recurrence diagnosis, but there is no consensus about the best PSA threshold to define BCR until this moment. The natural history of BCR after surgical procedure is highly variable, but it is important to distinguish biochemical and clinical recurrence and to find the correct timing to start multimodal treatment strategy. Also, it is important to understand the role of each clinical and pathological feature of prostate cancer in BCR, progression to metastatic disease and cancer specific mortality (CSM). Review design A simple review was made in Medline for articles written in English language about biochemical recurrence after radical prostatectomy. Objective To provide an updated assessment of BCR definition, its meaning, PCa natural history after BCR and the weight of each clinical/pathological feature and risk group classifications in BCR, metastatic disease and CSM.

Robot assisted prostatectomy (RAP) is more costly than traditional radical retropubic prostatectomy (RRP) under the cost structures at certain hospitals. However, this finding may not be the case in all care settings. We investigated the sensitivity of RAP and RRP inpatient costs to variations in length of stay (LOS), local hospitalization costs and robotic case volume in the specialist and generalist settings. We developed a model of RAP vs RRP costs in the specialist and generalist settings using published data on operative time and LOS, and cost data from our academic medical center. All inpatient cost centers were included, namely surgery costs, professional fees, postoperative care, robotic equipment and service. Extensive 1 and 2-way sensitivity analyses were performed. Our base case model demonstrated a cost premium for RAP vs RRP of USD $783 and $195 in the specialist and generalist settings, respectively. Sensitivity analysis of our model assumptions demonstrated that RAP could achieve cost equivalence with RRP at a surgical volume of 10 cases weekly. If case volume increased to 14 cases weekly, RAP would be less expensive than RRP in some practice settings in which RAP LOS was less than 1.5 days. The inpatient costs of robotic assisted prostatectomy are volume dependent and cost equivalence with generalist radical retropubic prostatectomy is possible at higher volume RAP specialty centers. While RAP may be cost competitive with RRP at high cost hospitals or high volume RAP specialist centers, this procedure would exist at a cost premium to RRP in other practice settings.

To develop a methodology for predicting operative times for robot-assisted radical prostatectomy (RARP) using preoperative patient, disease, procedural and surgeon variables to facilitate operating room (OR) scheduling. The model included preoperative metrics: BMI, ASA score, clinical stage, National Comprehensive Cancer Network (NCCN) risk, prostate weight, nerve-sparing status, extent and laterality of lymph node dissection, and operating surgeon (6 surgeons were included in the study). A binary decision tree was fit using a conditional inference tree method to predict operative times. The variables most associated with operative time were determined using permutation tests. The data was split at the value of the variable that results in the largest difference in means for surgical time across the split. This process was repeated recursively on the resultant data. 1709 RARPs were included. The variable most strongly associated with operative time was the surgeon (surgeons 2 and 4 - 102 minutes shorter than surgeons 1, 3, 5, and 6, p<0.001). Among surgeons 2 and 4, BMI had the strongest association with surgical time (p<0.001). Among patients operated by surgeons 1, 3, 5 and 6, RARP time was again most strongly associated with the surgeon performing RARP. Surgeons 1, 3, and 6 were on average 76 minutes faster than surgeon 5 (p<0.001). The regression tree output in the form of box plots showed operative time median and ranges according to patient, disease, procedural and surgeon metrics. We developed a methodology that can predict operative times for RARP based on patient, disease and surgeon variables. This methodology can be utilized for quality control, facilitate OR scheduling and maximize OR efficiency.

To analyze the influential factors in the response in prostatectomized patients with subsequent biochemical relapse (BCR) and treated with salvage radiotherapy (RTP). We analyzed 313 patients with pT2/pT3 prostate cancer who were receiving salvage therapy due to biochemical relapse (from a series of 1,310 radical prostatectomies between 1989-2012). Of the 313 patients; 159 (50.8%) only received androgen deprivation (AD), 63 (20.1%) Radiotherapy (RTP) plus concomitant AD and 91 (29.1%) only RTP. Of these, 57 (62.6%) have maintained complete response and 34 (37.4%) had failure response with post-RTP BCR. Study of the group treated exclusively with salvage RTP. Ninety-one patients were treated with salvage RTP. Median follow-up was 6.4 years and median to recurrence 11 months. Post-RTP biochemical relapse-free survival (PRBRFS) was 68 ± 7% and 30 ± 10% in 5 to 10 years. Median PRBRFS was 7.3 years (6.3-8.3). Initial PSA (HR: 1.08; 95% CI: 1.01-1.1 P=.02) with best PSA cut-off point PSA>20 ng/ml (HR: 13.6; 95% CI: 2.1-86 P=.005) and PSA pre-RTP (HR: 1.9; 95% CI: 1.2-3.3; P=.009), best PSA cut-off point PSA preRTP 0.92 ng/ml (HR: 4.5; 95% CI: 1.3-15.6; P=.01) showed independent influence in the response in the multivariate study. PRBRFS at 5 years, 81 ± 9% versus 58 ± 9% with initial PSA <20 or >20 ng/ml (P=.03). PRBRFS at 5 years, 93 ± 5% versus 53 ± 10% according to PSA pre-RTP <0.9 or >0.9 ng/ml (P=.02). In patients treated with salvage RTP after radical prostatectomy, the preoperative PSA>20 ng/ml and PSA preRTP>0.92 ng/ml shows an independent influence on the response. Copyright © 2013 AEU.

Objective: evaluate the general and perceived self-efficacy, psychological morbidity, and knowledge about postoperative care of patients submitted to radical prostatectomy. Identify the relationships between the variables and know the predictors of self-efficacy. Method: descriptive, cross-sectional study, conducted with 76 hospitalized men. The scales used were the General and Perceived Self-efficacy Scale and the Hospital Anxiety and Depression Scale, in addition to sociodemographic, clinical and knowledge questionnaires. Results: a negative relationship was found for self-efficacy in relation to anxiety and depression. Psychological morbidity was a significant predictor variable for self-efficacy. An active professional situation and the waiting time for surgery also proved to be relevant variables for anxiety and knowledge, respectively. Conclusion: participants had a good level of general and perceived self-efficacy and small percentage of depression. With these findings, it is possible to produce the profile of patients about their psychological needs after radical prostatectomy and, thus, allow the nursing professionals to act holistically, considering not only the need for care of physical nature, but also of psychosocial nature.

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsy before radical prostatectomy. The aim of our study was to evaluate whether the interval from prostate biopsy to radical prostatectomy affects immediate operative outcomes, with a focus on differences in surgical approach. The study population of 1,848 radical prostatectomy patients was divided into two groups according to the surgical approach: open or minimally invasive. Open group included perineal and retropubic approach, and minimally invasive group included laparoscopic and robotic approach. The cut-off of the biopsy-to-surgery interval was 4 weeks. Positive surgical margin status, operative time and estimated blood loss were evaluated as endpoint parameters. In the open group, there were significant differences in operative time and estimated blood loss between the <4-week and ≥4-week interval subgroups, but there was no difference in positive margin rate. In the minimally invasive group, there were no differences in the three outcome parameters between the two subgroups. Multivariate analysis revealed that the biopsy-to-surgery interval was not a significant factor affecting immediate operative outcomes in both open and minimally invasive groups, with the exception of the interval ≥4 weeks as a significant factor decreasing operative time in the minimally invasive group. In conclusion, performing open or minimally invasive radical prostatectomy within 4 weeks of prostate biopsy is feasible for both approaches, and is even beneficial for minimally invasive radical prostatectomy to reduce operative time.

To evaluate the impact of nerve-sparing (NS) approach on outcomes of patients undergoing minimally invasive radical hysterectomy (MRH) for locally advanced stage cervical cancer (LACC). Data of consecutive patients undergoing minimally invasive surgery for LACC were retrospectively retrieved in a multi-institutional setting from 2009 to 2016. All patients included had minimally invasive class III radical hysterectomy (MRH or NS-MRH). Propensity matching algorithm was used to decrease possible allocation bias when comparing outcomes between groups. Overall, 83 patients were included. The prevalence of patients undergoing NS approach increased aver the study period (from 7% in the year 2009-2010 to 97% in the year 2015-2016; p-for-trend < 0.001). NS-MRH and MRH were performed in 47 (57%) and 36 (43%) patients, respectively. After the application the propensity-matching algorithm, we compared 35 patients' pair (total 70 patients). Postoperative complications rate was similar between groups. Patients undergoing NS-LRH experienced shorter hospital stay than patients undergoing LRH (3.6 vs. 5.0 days). 60-day pelvic floor dysfunction rates, including voiding, fecal and sexual alterations, were lower in the NS group in comparison to control group (p = 0.02). Five-year disease-free (p = 0.77) and overall (p = 0.36) survivals were similar comparing NS-MRH with MRH. The implementation of NS approach in the setting of LACC improves patients' outcomes, minimizing pelvic dysfunction rates. NS approach has not detrimental effects on survival outcomes.

Detailed knowledge of the anatomy of the prostate and adjacent tissues is mandatory during radical prostatectomy to ensure reliable oncologic and functional outcomes. To review critically and to summarize the available literature on surgical anatomy of the prostate and adjacent structures involved in cancer control, erectile function, and urinary continence. A search of the PubMed database was performed using the keywords radical prostatectomy, anatomy, neurovascular bundle, fascia, pelvis, and sphincter. Relevant articles and textbook chapters were reviewed, analyzed, and summarized. Anatomy of the prostate and the adjacent tissues varies substantially. The fascia surrounding the prostate is multilayered, sometimes either fused with the prostate capsule or clearly separated from the capsule as a reflection of interindividual variations. The neurovascular bundle (NVB) is situated between the fascial layers covering the prostate. The NVB is composed of numerous nerve fibers superimposed on a scaffold of veins, arteries, and variable amounts of adipose tissue surrounding almost the entire lateral and posterior surfaces of the prostate. The NVB is also in close, cage-like contact to the seminal vesicles. The external urethral sphincter is a complex structure in close anatomic and functional relationship to the pelvic floor, and its fragile innervation is in close association to the prostate apex. Finally, the shape and size of the prostate can significantly modify the anatomy of the NVB, the urethral sphincter, the dorsal vascular complex, and the pubovesical/puboprostatic ligaments. The surgical anatomy of the prostate and adjacent tissues involved in radical prostatectomy is complex. Precise knowledge of all relevant anatomic structures facilitates surgical orientation and dissection during radical prostatectomy and ideally translates into both superior rates of cancer control and improved functional outcomes postoperatively.

Background Prostate-specific antigen (PSA) testing is recommended every 6 to 12 months for the first 5 years following radical prostatectomy as a means to detect potential disease recurrence. Despite substantial research on factors affecting treatment decisions, recurrence, and mortality, little is known about whether men receive guideline-concordant surveillance testing or whether receipt varies by year of diagnosis, time since treatment, or other individual characteristics. Methods Surveillance testing following radical prostatectomy among elderly men was examined using Surveillance, Epidemiology, and End Results cancer registry data linked to Medicare claims. Multivariate logistic regression was used to examine the effect of demographic, tumor, and county-level characteristics on the odds of receiving surveillance testing within a given one-year period following treatment. Results Overall, receipt of surveillance testing was high, with 96% of men receiving at least one test the first year after treatment and approximately 80% receiving at least one test in the fifth year after treatment. Odds of not receiving a test declined with time since treatment. Non-married men, men with less advanced disease, and non-Hispanic Blacks and Hispanics had higher odds of not receiving a surveillance test. Year of diagnosis did not affect the receipt of surveillance tests. Conclusion Most men receive guideline-concordant surveillance PSA testing after prostatectomy, although evidence of a racial disparity between non-Hispanic Whites and some minority groups exists. The decline in surveillance over time suggests the need for well-designed long-term surveillance plans following radical prostatectomy. PMID:23893821

Perez, Bradford A; Koontz, Bridget F

2015-05-01

Men with localized high-risk prostate cancer carry significant risk of prostate cancer-specific mortality. The best treatment approach to minimize this risk is unclear. In this review, we evaluate the role of radiation before and after radical prostatectomy. A critical review of the literature was performed regarding the application of external radiation therapy (RT) in combination with prostatectomy for high-risk localized prostate cancer. Up to 70% of men with high-risk localized disease may require adjuvant therapy because of adverse pathologic features or biochemical recurrence in the absence of systemic disease. The utility of adjuvant RT among men with adverse pathologic features are well established at least regarding minimizing biochemical recurrence risk. The optimal timing of salvage radiation is the subject of ongoing studies. Neoadjuvant RT requires further study but is a potentially attractive method because of decreased radiation field sizes and potential radiobiologic benefits of delivering RT before surgery. Salvage prostatectomy is effective at treating local recurrence after radiation but is associated with significant surgical morbidity. Combining local therapies including radical prostatectomy and RT can be a reasonable approach. Care should be taken at the initial presentation of high-risk localized prostate cancer to consider and plan for the likelihood of multimodality care. Copyright © 2015 Elsevier Inc.

A growing number of men undergo repeat biopsies prior to radical prostatectomy for prostate cancer. However, the long-term impact of repeat biopsies on functional outcomes in this patient population remains unelucidated. Thus, we compared functional outcomes between patients who underwent single biopsy versus repeat biopsies before radical prostatectomy. From 1996 to 2015, 1015 consecutive patients underwent radical prostatectomy, and subsequently had urinary continence and erectile function assessed for >2 years follow-up. One-fourth of patients (275; 27%) had ≥2 biopsies before prostatectomy. Logistic regression models tested whether repeat biopsy before prostatectomy predicted continence or erectile function recovery. For the overall cohort, continence rates were 84%, 92%, 96%, and 98% at 3, 6, 12, and 24 months, respectively. Repeat biopsy before prostatectomy was associated with lower continence rate at 3 months compared to single biopsy (P = 0.03); however, no significant differences were observed at 6, 12, or 24 months. In multivariable analyses adjusting for age, body mass index and diabetes/cardiovascular disease/smoking, the association between repeat biopsy and lower likelihood of continence at 3 months remained (odds ratio 0.67, 95% confidence interval 0.47-0.97; P = 0.03). Overall erectile function recovery rates were 16%, 33%, 51%, and 55% at 3, 6, 12, and 24 months, respectively. No difference in erectile function recovery rates was seen at any time point for single biopsy versus repeat biopsy. In multivariable analyses, repeat biopsy was not predictive of erectile function recovery at any time point. Repeat biopsy before radical prostatectomy impairs early continence after surgery. However, erectile function recovery and mid-term to long-term continence are not affected. These data support the current trend towards active surveillance and delayed local treatment in patients with low- to intermediate-risk prostate cancer. © 2018 Wiley

• Many experts consider that media coverage, marketing and/or direct-to-consumer advertising, particularly Internet-based forms, are fundamental to the widespread adoption of robotic-assisted prostatectomy (RARP). However, this has not been explored previously. • The primary objective of the present study was to delineate the role of media coverage and marketing of RARP on the Internet, whereas the secondary goal focused on website quality with respect to the presentation of prostatectomy. • Website content was evaluated for direct-to-consumer advertising after the retrieval of the first 50 websites using Google and Yahoo for each of the terms: 'robotic prostatectomy, laparoscopic prostatectomy (LP) and open radical prostatectomy (ORP)'. • A linear regression analysis was performed for the annual number of Internet news hits over the last decade for each procedure. Website quality assessment was performed using WHO Honesty on the Internet (HON) code principles. • Of the retrieved sites, the proportion containing direct-to-consumer advertising for RARP vs LP vs ORP using Google was 64% vs 14% vs 0%, respectively (P < 0.001) and, using Yahoo, 80% vs 16% vs 0%, respectively (P < 0.001). • In a linear regression analysis, the r(2) values for news hits for each year over the last 10 years were 0.89, 0.74 and 0.76 for RARP, LP and ORP, respectively. • Website quality assessment found that a minority of the websites were accredited with HONcode principles, with no difference between procedure types (P > 0.05). • Media coverage and marketing of RARP on the Internet is more widespread compared to LP and ORP. • Disturbingly, the quality of websites using any technique for prostatectomy was of poor quality when using principles of honest information presenting and such findings need to be discussed with respect to obtaining informed consent from patients. © 2011 THE AUTHORS.

Incidence of prostate cancer has been increasing in recent decades. In the year 2005, prostate cancer became the second most common cancer in males in Macau. The purpose of this report was to review and summarize the clinical features and prognosis of the 54 patients undergoing radical prostatectomy in Macau Special Administrative Region (SAR), China. From November 2000 to November 2006, retropubic radical prostatectomy were performed in 54 cases for the treatment of prostate cancer. The mean age of patients was 69.8 years (range from 54 to 79). The preoperative prostate specific antigen (PSA) level, postoperative pathologic stage and Gleason's score, operation duration, intraoperative bleeding and intraoperative and postoperative complications were reported. The follow-up duration was 3 months to 6.25 years with a mean of 2.1 years. Postoperative parameters including PSA alteration, biochemical recurrence, local recurrence, distant metastasis and mortality were observed. Most of the patients in our study were diagnosed as localized prostate cancer. The patients' preoperative serum PSA was 0-4.0 ng/ml (16.7%), 4.0-10.0 ng/ml (51.8%), 10.1-20.0 ng/ml (24.1%) and above 20.0 ng/ml (7.4%). The TNM stage T1a+T1b comprised 7.6% of patients, stage T2a+T2b comprised 20.3%, stage T2c 38.9%, stage T3a 20.3% and over T3a only 12.9%. There were 9.5% cases with Gleason scores of 2-4, 41.5% with scores of 5-6, 30.2% with scores of 7 and 18.8% with scores of 8 - 10. The average operative duration was 216 minutes and the average intraoperative bleeding was 760 ml. Intraoperative complications included one massive hemorrhage (1.9%), one rectal injury (1.9%) and one obturator nerve injury (1.9%). Early postoperative complications consisted of urinary incontinence (14 cases, 25.9%), bladder neck stricture (5 cases, 9.3%), acute urinary retention (4 cases, 7.4%), pelvic effusion (2 cases, 3.8%), lymphocele (1 case, 1.9%) and vesicorectal fistula (only 1 case, 1.9%).

Inflammation is commonly observed in radical prostatectomy specimens, and evidence suggests that inflammation may contribute to prostate carcinogenesis. Multiple microorganisms have been implicated in serving as a stimulus for prostatic inflammation. The pro-inflammatory anaerobe, Propionibacterium acnes, is ubiquitously found on human skin and is associated with the skin disease acne vulgaris. Recent studies have shown that P. acnes can be detected in prostatectomy specimens by bacterial culture or by culture-independent molecular techniques. Radical prostatectomy tissue samples were obtained from 30 prostate cancer patients and subject to both aerobic and anaerobic culture. Cultured species were identified by 16S rDNA gene sequencing. Propionibacterium acnes isolates were typed using multilocus sequence typing (MLST). Our study confirmed that P. acnes can be readily cultured from prostatectomy tissues (7 of 30 cases, 23%). In some cases, multiple isolates of P. acnes were cultured as well as other Propionibacterium species, such as P. granulosum and P. avidum. Overall, 9 of 30 cases (30%) were positive for Propionibacterium spp. MLST analyses identified eight different sequence types (STs) among prostate-derived P. acnes isolates. These STs belong to two clonal complexes, namely CC36 (type I-2) and CC53/60 (type II), or are CC53/60-related singletons. MLST typing results indicated that prostate-derived P. acnes isolates do not fall within the typical skin/acne STs, but rather are characteristic of STs associated with opportunistic infections and/or urethral flora. The MLST typing results argue against the likelihood that prostatectomy-derived P. acnes isolates represent contamination from skin flora. Copyright © 2012 Wiley Periodicals, Inc.

To evaluate the efficacy and safety of laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in patients who have undergone robot-assisted laparoscopic radical prostatectomy (RALP). From July 2014 to December 2016, TAPP inguinal hernia repair was conducted in 40 consecutive patients who had previously undergone RALP. Their data were retrospectively analyzed as an uncontrolled case series. The mean operation time in patients who had previously undergone RALP was 99.5 ± 38.0 min. The intraoperative blood loss volume was small, and the duration of hospitalization was 2.0 ± 0.5 days. No intraoperative complications or major postoperative complications occurred. During the average 11.2-month follow-up period, no patients who had previously undergone prostatectomy developed recurrence. Laparoscopic TAPP inguinal hernia repair after RALP was safe and effective. TAPP inguinal hernia repair may be a valuable alternative to open hernioplasty.

Increases in serum levels of prostate-specific antigen (PSA) occur commonly in prostate cancer after radical prostatectomy and are designated "biochemical recurrence." Because the phytochemical sulforaphane has been studied extensively as an anticancer agent, we performed a double-blinded, randomized, placebo-controlled multicenter trial with sulforaphane in 78 patients (mean age, 69 ± 6 years) with increasing PSA levels after radical prostatectomy. Treatment comprised daily oral administration of 60 mg of a stabilized free sulforaphane for 6 months (M0-M6) followed by 2 months without treatment (M6-M8). The study was designed to detect a 0.012 log (ng/mL)/month decrease in the log PSA slope in the sulforaphane group from M0 to M6. The primary endpoint was not reached. For secondary endpoints, median log PSA slopes were consistently lower in sulforaphane-treated men. Mean changes in PSA levels between M6 and M0 were significantly lower in the sulforaphane group (+0.099 ± 0.341 ng/mL) than in placebo (+0.620 ± 1.417 ng/mL; P = 0.0433). PSA doubling time was 86% longer in the sulforaphane than in the placebo group (28.9 and 15.5 months, respectively). PSA increases >20% at M6 were significantly greater in the placebo group (71.8%) than in the sulforaphane group (44.4%); P = 0.0163. Compliance and tolerance were very good. Sulforaphane effects were prominent after 3 months of intervention (M3-M6). After treatment, PSA slopes from M6 to M8 remained the same in the 2 arms. Daily administration of free sulforaphane shows promise in managing biochemical recurrences in prostate cancer after radical prostatectomy. ©2015 American Association for Cancer Research.

Single nucleotide polymorphisms are inherited genetic variations that can predispose or protect individuals against clinical events. We hypothesized that single nucleotide polymorphism profiling may improve the prediction of biochemical recurrence after radical prostatectomy. We performed a retrospective, multi-institutional study of 703 patients treated with radical prostatectomy for clinically localized prostate cancer who had at least 5 years of followup after surgery. All patients were genotyped for 83 prostate cancer related single nucleotide polymorphisms using a low density oligonucleotide microarray. Baseline clinicopathological variables and single nucleotide polymorphisms were analyzed to predict biochemical recurrence within 5 years using stepwise logistic regression. Discrimination was measured by ROC curve AUC, specificity, sensitivity, predictive values, net reclassification improvement and integrated discrimination index. The overall biochemical recurrence rate was 35%. The model with the best fit combined 8 covariates, including the 5 clinicopathological variables prostate specific antigen, Gleason score, pathological stage, lymph node involvement and margin status, and 3 single nucleotide polymorphisms at the KLK2, SULT1A1 and TLR4 genes. Model predictive power was defined by 80% positive predictive value, 74% negative predictive value and an AUC of 0.78. The model based on clinicopathological variables plus single nucleotide polymorphisms showed significant improvement over the model without single nucleotide polymorphisms, as indicated by 23.3% net reclassification improvement (p = 0.003), integrated discrimination index (p <0.001) and likelihood ratio test (p <0.001). Internal validation proved model robustness (bootstrap corrected AUC 0.78, range 0.74 to 0.82). The calibration plot showed close agreement between biochemical recurrence observed and predicted probabilities. Predicting biochemical recurrence after radical prostatectomy based on

Veno-occlusive dysfunction (formerly called "venous leakage") is a clinical-radiographic manifestation of a multi-aetiology syndrome, the pathogenesis of which is to be sought in intrinsic damage to the erectile tissue. It has been attributed to psycho-neurogenic, neurovascular and local--physical factors. The unsatisfactory results of the various surgical techniques proposed (venous ligatures, crural plication, corporopexy) can be explained by the formation of vicarious venous circles, a phenomenon which occurs regardless of the type of procedure adopted and which is the direct consequence of the alteration of the occlusive mechanisms intrinsic to the erectile tissue. At the Urological Institute of the University of Milan, a study has been carried out with the aim of experimentally assessing these aetiopathogenetic hypotheses. 48 sexually potent patients were selected from those scheduled for extensive surgical procedures on account of malignant pathologies of the pelvic cavity (urethro-prostato-cystectomy, radical prostatectomy). The protocol included a series of examinations before and after the operation (at three months): computerised recording of nocturnal erections (NPT test, three consecutive nights), dynamic penile Doppler velocimetry, dynamic cavernosometry/graphy, examination of bulbocavernosus reflex. The goal of the study was to evaluate the haemodynamic consequences of the massive venous ligatures effected during these operations (periprostatic plexus, deep dorsal vein, spongio-cavernous connections). There were 28 cases of radical prostatectomy and 20 cases of radical urethro-prostato-cystectomy. Among the cases of radical prostatectomy, the extrafascial retropubic technique was used for 14 patients, the monolateral nerve-sparing procedure was applied for 10 patients (stage B1) and the transperineal approach was used for 4 patients (the most recent).(ABSTRACT TRUNCATED AT 250 WORDS)

To report experience with combined therapy using intracorporal injection (ICI) of alprostadil and oral phosphodiesterase 5 (PDE-5) inhibitors for the minimally invasive treatment of erectile dysfunction (ED) after radical prostatectomy (RP), as PDE-5 inhibitors are effective but a few patients may have a suboptimal response. In a retrospective study, 34 men (aged 46-66 years) had a nerve-sparing retropubic RP and subsequent ED. Patients were titrated on sildenafil citrate or vardenafil to maximum doses. All had a suboptimal response after a maximum of eight doses of oral therapy and were then treated with ICI therapy using 15 or 20 microg alprostadil. Erectile function was assessed with the Sexual Health Inventory for Men (SHIM). Of the 32 patients who continued combined therapy, 22 (68%) had an improvement in erectile function after ICI therapy, as assessed by the SHIM score. On follow-up, 36% of these patients used ICI therapy only intermittently, instead of regularly, as they felt that this was adequate enough for good results. PDE-5 oral pharmacotherapy is the most commonly used effective therapy for ED but may not be as effective in patients who have radical surgery; the addition of testosterone patches may have side-effects or be considered a risk in patients with a history of prostate cancer. The use of ICI therapy as an adjunct or maintenance therapy to their oral medication may be another alternative in these patients.

Physical activity is recognized as a complementary therapy to improve physical and physiological functions among prostate cancer survivors. Little is known about communication between health providers and African-American prostate cancer patients, a high risk population, regarding the health benefits of regular physical activity on their prognosis and recovery. This study explores African-American prostate cancer survivors' experiences with physical activity prescription from their physicians. Three focus group interviews were conducted with 12 African-American prostate cancer survivors in May 2014 in St. Louis, MO. Participants' ages ranged from 49 to 79 years, had completed radical prostatectomy, and their time out of surgery varied from 7 to 31 months. Emerged themes included physician role on prescribing physical activity, patients' perceived barriers to engaging in physical activity, perception of normalcy following surgery, and specific resources survivors' sought during treatment. Of the 12 men who participated, 8 men (67%) expressed that their physicians did not recommend physical activity for them. Although some participants revealed they were aware of the importance of sustained physical activity on their prognosis and recovery, some expressed concerns that urinary dysfunction, incontinence, and family commitments prevented them from engaging in active lifestyles. Transitioning from post radical prostatectomy treatment to normal life was an important concern to survivors. These findings highlight the importance of physical activity communication and prescription for prostate cancer patients.

Retzius space sparing (RSS) during laparoscopic robot-assisted radical prostatectomy (RALP) has been offered as an approach that reduces perioperative complications and enables faster gaining of full urinary continence due to bladder anatomy preservation. Retro and transperitoneal techniques have been proposed, whereby RSS has been implemented. We sought to explore whether Retzius space reconstruction (RSR) following transperitoneal RALP will be an advantageous step as well. A prospective registry database of 102 consecutive transperitoneal RALP cases performed by a single surgeon was reviewed. The Retzius space had been opened by dissecting the bladder away from the anterior abdominal wall to the level of both internal rings. In the last 51 cases (RSR group), the peritoneal layer had been sutured back, thus repositioning the bladder back to the anterior abdominal wall and reconstructing the Retzius space. Perioperative factors were analyzed and compared between the two groups. Demographic and perioperative data did not differ between the two groups. RSR group demonstrated shorter length of stay (LOS) compared with the control group (p = 0.01), as well as faster urinary continence recovery (i.e., 0 pads) (p = 0.01). Moreover, lower numbers of Clavien-Dindo class 3 complications and 12 mm port-site hernias (p = 0.03) were seen in the RSR group compared with the control group. RSR following transperitoneal RALP is a simple and efficient step that potentially reduces early and late post-operative complications, shortens LOS and accelerates full urinary continence.

To compare the predictive ability of primary and secondary Gleason pattern for positive surgical margins in patients with clinically localized prostate cancer and a preoperative Gleason score ≤ 6. A retrospective analysis of the medical records of patients undergone a radical prostatectomy between January 2005 and October 2010 was conducted. Patients' age, prostate volume, preoperative PSA, biopsy Gleason score, the 1st and 2nd Gleason pattern were entered a univariate and multivariate analysis. The 1st and 2nd pattern were tested for their ability to predict positive surgical margins using receiver operating characteristic curves. Positive surgical margins were noticed in 56 cases (38.1%) out of 147 studied patients. The 2nd pattern was significantly greater in those with positive surgical margins while the 1st pattern was not significantly different between the 2 groups of patients. ROC analysis revealed that area under the curve was 0.53 (p=0.538) for the 1st pattern and 0.60 (p=0.048) for the 2nd pattern. Concerning the cases with PSA <10 ng/ml, it was also found that only the 2nd pattern had a predictive ability (p=0.050). When multiple logistic regression analysis was conducted it was found that the 2nd pattern was the only independent predictor. The second Gleason pattern was found to be of higher value than the 1st one for the prediction of positive surgical margins in patients with preoperative Gleason score ≤ 6 and this should be considered especially when a neurovascular bundle sparing radical prostatectomy is planned, in order not to harm the oncological outcome.

Androgen deprivation is commonly prescribed for men with a rising prostate specific antigen level after radical prostatectomy, despite scant evidence regarding its efficacy and side effects. In the current study, the authors compared measures of health-related quality of life (HRQOL) in men who were treated with androgen deprivation after radical prostatectomy with those for men who underwent surgery but were not treated with androgen deprivation. Medicare Provider and Analysis and Review (MedPAR) files were used to identify men who had undergone radical prostatectomies between 1991-1992. Medicare Part B data then were used to select two samples: men who subsequently were androgen deprived and those who were not. In 1999, a mail survey was administered that addressed a range of disease-related and treatment-related issues, including HRQOL. Age-adjusted comparisons of responses to seven multiitem measures of HRQOL were performed. The overall response rate was 82%. On all seven HRQOL measures (impact of cancer and treatment, concern regarding body image, mental health, general health, activity, worries about cancer and dying, and energy), there were statistically significant decrements associated with androgen deprivation. Patients and physicians must weigh the price patients pay with regard to HRQOL against the uncertain benefits of early androgen deprivation.

Research of predictive factors of biochemical recurrence to guide the establishment of an adjuvant treatment after radical prostatectomy for cancer with positive surgical margins. A retrospective cohort of 1577 afro-caribbean patients undergoing radical prostatectomy operated between 1st January 2000 and 1st July 2013 was analyzed. In this cohort, 406 patients had positive surgical margin, we excluded 11 patients who received adjuvant therapy (radiotherapy, hormonotherapy, radio-hormonotherapy) and 2 patients for whom histological analysis of the surgical specimen was for a pT4 pathological stage. After a descriptive analysis, we used a Cox model to look for predictors of survival without biochemical recurrence then, depending on the significant variables, we separated our population into six groups: stage pT2 with Gleason score≤3+4 (group 1), stage pT2 with a score of Gleason≥4+3 (group 2), stage pT3a with a Gleason core≤3+4 (group 3), pT3a stage with a score of Gleason≥4+3 (group 4), stage pT3b with a Gleason score≤3+4 (group 5) and stage pT3b Gleason≥with a score of 4+3 (group 6) and compared survival without biochemical recurrence using a log rank test. After radical prostatectomy with surgical margins with an anatomopathological stage≤pT3b, a Gleason score≥4+3 had a pejorative survival without biochemical recurrence than pathological stage (P<0.001). In multivariate analysis, predictors of survival without biochemical recurrence after radical prostatectomy with positive surgical margins were the majority Gleason postoperative (P<0.0001), pathological stage (P=0.049) adjusted preoperative PSA (P=0.826), with the body mass index (BMI) (P=0.59) and tumor volume (P=0.95). A high postoperatively Gleason score (≥4+3) has a better predictive value of biochemical recurrence than pathological stage pT2 or pT3 at the patients having been treated for prostate cancer by radical prostatectomy with positive surgical margins. 4.

HRQOL, based on the expanded prostate cancer index composite (EPIC) and SF-8 questionnaires, was prospectively compared after either a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) at a single institute. Between October 2005 and June 2007, 96 patients were treated by an RRP and 88 patients were treated by a PPB. A HRQOL survey was completed at baseline, and at 1, 3, 6 and 12 months after treatment, prospectively. The general HRQOL in the RRP and PPB groups was not different after 3 months. However, at baseline and 1 month after treatment, the mental component summary was significantly better in the PPB group than in the RRP group. Moreover, the disease-specific HRQOL was worse regarding urinary and sexual functions in the RRP group. Urinary irritative/obstructive was worse in the PPB group, but urinary incontinence was worse in the RRP group and had not recovered to baseline after 12 months. The bowel function and bother were worse in the PPB group than in the RRP group after 3 months. In the RRP group, the patients with nerve sparing demonstrated the same scores in sexual function as the PPB group. This prospective study revealed the differences in the HRQOL after an RRP and PPB. Disease-specific HRQOL is clarified by using EPIC survey. These results will be helpful for making treatment decisions.

To assess patients' symptoms, quality of life and satisfaction with information three to four years after radical prostatectomy, radical external beam radiotherapy and postoperative radiotherapy and to analyse differences between treatment groups and the relationship between disease-specific, health-related and overall quality of life and satisfaction with information. Radical prostate cancer treatments are associated with changes in quality of life. Differences between patients undergoing different treatments in symptoms and quality of life have been reported, but there are limited long-term data comparing radical prostatectomy with radical external beam radiotherapy and postoperative radiotherapy. A cross-sectional survey design was used. The study sample included 143 men treated with radical prostatectomy and/or radical external beam radiotherapy. Quality of life was measured using the 12-item Short Form Health Survey and the 50-item Expanded Prostate Cancer Index Composite Instrument. Questions assessing overall Quality of life and satisfaction with information were included. Descriptive statistics and interference statistical methods were applied to analyse the data. Radical external beam radiotherapy was associated with less urinary incontinence and better urinary function. There were no differences between the groups for disease-specific quality of life sum scores. Sexual quality of life was reported very low in all groups. Disease-specific quality of life and health-related quality of life were associated with overall quality of life. Patients having undergone surgery were more satisfied with information, and there was a positive correlation between quality of life and patient satisfaction. Pretreatment information and patient education lead to better quality of life and satisfaction. This study indicates a need for structured, pretreatment information and follow-up for all men going through radical prostate cancer treatment. Long-term quality of life

We sought to apply the principles of human factors research to robotic-assisted radical prostatectomy to understand where training and integration challenges lead to suboptimal and inefficient care. Thirty-four robotic-assisted radical prostatectomy and bilateral pelvic lymph node dissections over a 20 week period were observed for flow disruptions (FD) - deviations from optimal care that can compromise safety or efficiency. Other variables - physician experience, trainee involvement, robot model (S versus Si), age, body mass index (BMI), and American Society of Anesthesiologists (ASA) physical status - were used to stratify the data and understand the effect of context. Effects were studied across four operative phases - entry to insufflations, robot docking, surgical intervention, and undocking. FDs were classified into one of nine categories. An average of 9.2 (SD = 3.7) FD/hr were recorded, with the highest rates during robot docking (14.7 [SD = 4.3] FDs/hr). The three most common flow disruptions were disruptions of communication, coordination, and equipment. Physicians with more robotic experience were faster during docking (p < 0.003). Training cases had a greater FD rate (8.5 versus 10.6, p < 0.001), as did the Si model robot (8.2 versus 9.8, p = 0.002). Patient BMI and ASA classification yielded no difference in operative duration, but had phase-specific differences in FD. Our data reflects the demands placed on the OR team by the patient, equipment, environment and context of a robotic surgical intervention, and suggests opportunities to enhance safety, quality, efficiency, and learning in robotic surgery.

The aim of this study is to determine electromyographic pelvic floor muscles activity during the first 6 months post RRP and its relationship to urinary continence. Thirty-eight men (mean age of 63.1 ± 5.7 year) with prostate cancer scheduled for open radical retropubic prostatectomy were evaluated. pelvic radiotherapy, systemic or neurologic diseases, pre-operative International Prostate Symptoms Score (IPSS) >7 and OABq ≥8. Surface electromyography (sEMG) evaluation, IPSS, Urinary Distress Inventory, Incontinence Impact Questionnaire, and Overactive Bladder Questionnaire-short form were applied before and at 1, 3, and 6 months after RRP. Six months after surgery, 18 men (47.4 %) presented urinary leakage. The sEMG evaluations within the first 6 months presented changes in fast contraction amplitude (p = 0.006), rest amplitude after fast contraction (p = 0.04), 10 s sustained contraction mean amplitude (p = 0.024) and final rest amplitude (p = 0.011). We observed that continent and incontinent patients as a group presented electromyographic changes during the first 6 months after radical prostatectomy that could be justified by the denervation/reinnervation of the external urethral sphincter. This finding is consistent with the adaptation of the pelvic floor musculature to the new urethral sphincter condition following surgery.

To demonstrate any differences in the perioperative, functional and oncologic outcomes after radical retropubic prostatectomy (RRP) among those patients having previously performed transurethral resection of prostate (TURP) and those not. A total of 35 patients were diagnosed with prostate cancer (T1a and T1b) after TURP, underwent RRP and completed a 1 year follow up (group A). They were matched with a cohort of another 35 men (group B) in terms of age, body mass index (BMI), prostatic specific antigen (PSA), Gleason score, prostate volume (before surgery), pathological stage and neurovascular bundle-sparing technique. That was a retrospective study completed between September 2011 and March 2014. Not a significant difference was demonstrated among the two groups of patients concerning the functional and oncologic results. On the other hand, previous prostate surgery made the operation procedure more demanding. Besides, operative time and blood loss (though not translated in transfusion rates) were higher among patients in group A. Besides, catheter removal in group A patients was performed later than their counterparts of group B. RRP after TURP is a relatively safe procedure and in the hands of experienced surgeons, a previously performed TURP, does not seem to compromise oncologic outcomes of the operation. Continence is preserved, though erectile function seems to be compromised compared with patients undergoing RRP without prior TURP. Moreover, defining the prostate and bladder neck margins can be challenging and the surgeon has to be aware of the difficulties that might confront.

We evaluated single institution toxicity outcomes after post-prostatectomy radiotherapy (PPRT) via image-guided intensity-modulated radiation therapy (IG-IMRT) with implanted fiducial markers following national eviQ guidelines, for which late toxicity outcomes have not been published. Prospectively collected toxicity data were retrospectively reviewed for 293 men who underwent 64-66 Gy IG-IMRT to the prostate bed between 2007 and 2015. Median follow-up after PPRT was 39 months. Baseline grade ≥2 genitourinary (GU), gastrointestinal (GI) and sexual toxicities were 20.5%, 2.7% and 43.7%, respectively, reflecting ongoing toxicity after radical prostatectomy. Incidence of new (compared to baseline) acute grade ≥2 GU and GI toxicity was 5.8% and 10.6%, respectively. New late grade ≥2 GU, GI and sexual toxicity occurred in 19.1%, 4.7% and 20.2%, respectively. However, many patients also experienced improvements in toxicities. For this reason, prevalence of grade ≥2 GU, GI and sexual toxicities 4 years after PPRT was similar to or lower than baseline (21.7%, 2.6% and 17.4%, respectively). There were no grade ≥4 toxicities. Post-prostatectomy IG-IMRT using Australian contouring guidelines appears to have tolerable acute and late toxicity. The 4-year prevalence of grade ≥2 GU and GI toxicity was virtually unchanged compared to baseline, and sexual toxicity improved over baseline. This should reassure radiation oncologists following these guidelines. Late toxicity rates of surgery and PPRT are higher than following definitive IG-IMRT, and this should be taken into account if patients are considering surgery and likely to require PPRT. © 2017 The Royal Australian and New Zealand College of Radiologists.

Variation in care within and across geographic areas remains poorly understood. The goal of this article was to examine whether physician social networks-as defined by shared patients-are associated with rates of complications after radical prostatectomy. In five cities, we constructed networks of physicians on the basis of their shared patients in 2004-2005 Surveillance, Epidemiology and End Results-Medicare data. From these networks, we identified subgroups of urologists who most frequently shared patients with one another. Among men with localized prostate cancer who underwent radical prostatectomy, we used multilevel analysis with generalized linear mixed-effect models to examine whether physician network structure-along with specific characteristics of the network subgroups-was associated with rates of 30-day and late urinary complications, and long-term incontinence after accounting for patient-level sociodemographic, clinical factors, and urologist patient volume. Networks included 2677 men in five cities who underwent radical prostatectomy. The unadjusted rate of 30-day surgical complications varied across network subgroups from an 18.8 percentage-point difference in the rate of complications across network subgroups in city 1 to a 26.9 percentage-point difference in city 5. Large differences in unadjusted rates of late urinary complications and long-term incontinence across subgroups were similarly found. Network subgroup characteristics-average urologist centrality and patient racial composition-were significantly associated with rates of surgical complications. Analysis of physician networks using Surveillance, Epidemiology and End Results-Medicare data provides insight into observed variation in rates of complications for localized prostate cancer. If validated, such approaches may be used to target future quality improvement interventions. Copyright © 2014 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

Between 2004 and 2006, 50 radical prostatectomies were performed in our department, 46 of them through a laparoscopic approach addressed to early stage cancer (T1a,b,c and T2a,b,c N0 M0). We present the case of a 63 year old patient, who was initially diagnosed with prostate cancer in T1bN0M0 stage, Gleason score 8 and later presented atypical hepatic and trocar site metastases. This particular evolution of the case can be explained by the high value of the Gleason score and by the extension into microvessels observed on the sample prelevated by prostatectomy. The rarity of this atypical metastases and its association, the diagnostic and therapy problems are the reasons for the detailed presentation of this case.

We sought to evaluate post-operative return of urinary and sexual function in men undergoing robotic-assisted laparoscopic radical prostatectomy (RLRP). Prospective assessment of urinary continence and sexual function was performed in patients undergoing RLRP. Subjective assessment involved the use of the validated RAND-36 Item Health Survey/UCLA Prostate Cancer Index questionnaire. Questionnaires were completed pre-operatively and at 1, 3, 6 and 12 months post-operatively. Subset analyses were performed to assess the effect of age on functional outcomes. A total of 338 consecutive patients underwent RLRP between February 2003 and August 2005. Included patients for evaluation comprised of 21, 129, and 150 patients, aged <50, 50-59, and ≥60 years old, respectively. Kaplan-Meier curve analysis demonstrated that younger men (<60 years) achieved subjective continence significantly earlier than older age group (≥60 years) (P = 0.02). Continence rates, however, equalized among all age groups at 1 year follow-up. Younger men (<50 years) also demonstrated a quicker and greater return of sexual function (P = 0.01), which persisted through assessment at 1 year post-operatively. Our results suggest that younger men may have an earlier return of continence and potency when compared to men > 60 years. Despite this finding, continence outcomes appear to be equal among age groups after 1 year of follow-up. Moreover, men < 60 years continue to report superior potency outcomes compared to men > 60 years at 1 year post-operatively. Such findings are valuable in counseling patients undergoing RLRP.

Debate: Open radical prostatectomy vs. laparoscopic vs. robotic.

2007-01-01

Surgical removal of clinically localized prostate cancer remains the most definitive treatment for the disease. The emergence of laparoscopic and robotic radical prostatectomy (RP) as alternatives to open RP has generated considerable discussion about the real and relative merits of each approach. Such was the topic of a debate that took place during the 2006 Society of Urologic Oncology meeting. The participants were Dr. William Catalona, Northwestern University, advocating for open RP, Dr. Betrand Guillonneau, Memorial Sloan Kettering Cancer Center advocating for laparoscopic RP, and Dr. Mani Menon, Henry Ford Hospital, advocating for robotic RP. The debate was moderated by Dr. Joel Nelson, University of Pittsburgh. This paper summarizes that debate.

The neuroanatomical structures of the radical prostatectomy (RP) are extensively discussed for their existence, localization and function. Especially structures, e.g. the so-called neurovascular bundle (NVB) that are points of debate in numerous anatomical studies. We review the literature and present our observations in cadaveric specimens, to reconstruct neuroanatomical structures in three dimensions (3D) with the use of appropriate computer applications and produce images of operative fields. We used an internet PubMed survey (http://www.ncbi.nlm.nih.gov) to review recent publications and included back copies of historical neuroanatomical studies from our own library. Our own experimental cadaveric (specimens preserved in Thiel's solution) studies of the autonomic nerve supply of the lower urinary tract were also reviewed. Visualization of the pelvic anatomy and neuroanatomy was done using computer-based software packages. No unified terminology for the structures of the NVBs can be presented to date. The innervation of the smooth muscular structures of the urethra and the complex morphology of urethral sphincter remain unclear. Our cadaveric studies showed that nerves are located on the lateral aspect of the prostate in addition to the NVBs described at the dorsolateral side of the prostate. The neuroanatomical investigations of the male pelvis and visualization of the structures in 3D enable the presentation of operative sites as seen intraoperatively. Moreover, dynamic depiction of the pelvic floor is also possible.

In 2012, Japanese national insurance started covering robot-assisted surgery. We carried out a population-based comparison between robot-assisted and three other types of radical prostatectomy to evaluate the safety of robot-assisted prostatectomy during its initial year. We abstracted data for 7202 open, 2483 laparoscopic, 1181 minimal incision endoscopic, and 2126 robot-assisted radical prostatectomies for oncological stage T3 or less from the Diagnosis Procedure Combination database (April 2012–March 2013). Complication rate, transfusion rate, anesthesia time, postoperative length of stay, and cost were evaluated by pairwise one-to-one propensity-score matching and multivariable analyses with covariants of age, comorbidity, oncological stage, hospital volume, and hospital academic status. The proportion of robot-assisted radical prostatectomies dramatically increased from 8.6% to 24.1% during the first year. Compared with open, laparoscopic, and minimal incision endoscopic surgery, robot-assisted surgery was generally associated with a significantly lower complication rate (odds ratios, 0.25, 0.20, 0.33, respectively), autologous transfusion rate (0.04, 0.31, 0.10), homologous transfusion rate (0.16, 0.48, 0.14), lower cost excluding operation (differences, −5.1%, −1.8% [not significant], −10.8%) and shorter postoperative length of stay (–9.1%, +0.9% [not significant], –18.5%, respectively). However, robot-assisted surgery also resulted in a + 42.6% increase in anesthesia time and +52.4% increase in total cost compared with open surgery (all P < 0.05). Introduction of robotic surgery led to a dynamic change in prostate cancer surgery. Even in its initial year, robot-assisted radical prostatectomy was carried out with several favorable safety aspects compared to the conventional surgeries despite its having the longest anesthesia time and the highest cost.

Acquisition of the da Vinci surgical system (Intuitive Surgical, Mountain View, USA) has enabled robot-assisted surgery to become an acceptable alternative to open radical prostatectomy (ORP). Implementation of robotics at a single institution in Korea induced a gradual increase in the number of performances of robot-assisted laparoscopic radical prostatectomy (RALP) to surgically treat localized prostate cancer. We analyzed the impact of robotic instrumentation on practice patterns among urologists and explain the change in value in ORP and RALP-the standard treatment and the new approach or innovation of robotic technology. The overall number of prostatectomies has increased over time because the number of RALPs has grown drastically whereas the number of OPRs did not decrease during the period of evaluation. Our experience emphasizes the potential of RALP to become the gold standard in the treatment of localized prostate cancer in various parts of the world.

Several robot-assisted radical prostatectomy (RARP) series have reviewed the impact of the initial learning curve on perioperative outcomes. However, little is known about the impact of experience on urinary and sexual outcomes. Herein, we review the perioperative, pathological and functional outcomes of our initial 700 consecutive procedures with at least 1 year follow up. From 2003-2006, 700 consecutive men underwent RARP at a single, academic institution. Perioperative data and pathologic outcomes were prospectively collected. Validated, UCLA-PCI-SF36v2 quality-of-life questionnaires were also obtained at 1, 3, 6 and 12 months following surgery. Outcomes between groups (cases 1-300, 301-500, and 501-700) were compared. Mean operative time (OT) and blood loss significantly decreased during the experience (286, 198, 190 min; p or=7 in 24%, 40%, 44%; p postRARP, pad free continence rate was 81% when self reported and 62% when assessed by the UCLA-PCI-SF36v2 questionnaire in the initial group. Continence rates improved to 93% and 75%, respectively, for cases 501-700 (p nerve preservation) and 56% (unilateral nerve preservation) at 12 months when self reported and 63% and 37% respectively by the UCLA-PCI-SF36v2. No significant differences in sexual function were noted with increased experience. A prolonged learning curve is observed for EBL, OT and pT2-PSM. In addition, to the best of our knowledge, this is first series demonstrating a continued improvement in urinary continence with increased RARP experience.

Diaphragm-Sparing Nerve Blocks for Shoulder Surgery.

PubMed

Tran, De Q H; Elgueta, Maria Francisca; Aliste, Julian; Finlayson, Roderick J

Shoulder surgery can result in significant postoperative pain. Interscalene brachial plexus blocks (ISBs) constitute the current criterion standard for analgesia but may be contraindicated in patients with pulmonary pathology due to the inherent risk of phrenic nerve block and symptomatic hemidiaphragmatic paralysis. Although ultrasound-guided ISB with small volumes (5 mL), dilute local anesthetic (LA) concentrations, and LA injection 4 mm lateral to the brachial plexus have been shown to reduce the risk of phrenic nerve block, no single intervention can decrease its incidence below 20%. Ultrasound-guided supraclavicular blocks with LA injection posterolateral to the brachial plexus may anesthetize the shoulder without incidental diaphragmatic dysfunction, but further confirmatory trials are required. Ultrasound-guided C7 root blocks also seem to offer an attractive, diaphragm-sparing alternative to ISB. However, additional large-scale studies are needed to confirm their efficacy and to quantify the risk of periforaminal vascular breach. Combined axillary-suprascapular nerve blocks may provide adequate postoperative analgesia for minor shoulder surgery but do not compare favorably to ISB for major surgical procedures. One intriguing solution lies in the combined use of infraclavicular brachial plexus blocks and suprascapular nerve blocks. Theoretically, the infraclavicular approach targets the posterior and lateral cords, thus anesthetizing the axillary nerve (which supplies the anterior and posterior shoulder joint), as well as the subscapular and lateral pectoral nerves (both of which supply the anterior shoulder joint), whereas the suprascapular nerve block anesthetizes the posterior shoulder. Future randomized trials are required to validate the efficacy of combined infraclavicular-suprascapular blocks for shoulder surgery.

Objective The health-related quality of life (HRQOL) after treatment of prostate cancer is examined using a new HRQOL tool. HRQOL, based on the expanded prostate cancer index composite (EPIC) and SF-8 questionnaires, was prospectively compared after either a radical retropubic prostatectomy (RRP) or a permanent prostate brachytherapy (PPB) at a single institute. Methods Between October 2005 and June 2007, 96 patients were treated by an RRP and 88 patients were treated by a PPB. A HRQOL survey was completed at baseline, and at 1, 3, 6 and 12 months after treatment, prospectively. Results The general HRQOL in the RRP and PPB groups was not different after 3 months. However, at baseline and 1 month after treatment, the mental component summary was significantly better in the PPB group than in the RRP group. Moreover, the disease-specific HRQOL was worse regarding urinary and sexual functions in the RRP group. Urinary irritative/obstructive was worse in the PPB group, but urinary incontinence was worse in the RRP group and had not recovered to baseline after 12 months. The bowel function and bother were worse in the PPB group than in the RRP group after 3 months. In the RRP group, the patients with nerve sparing demonstrated the same scores in sexual function as the PPB group. Conclusions This prospective study revealed the differences in the HRQOL after an RRP and PPB. Disease-specific HRQOL is clarified by using EPIC survey.

To test the impact of surgeon experience on urinary continence (UC) recovery after robot-assisted radical prostatectomy (RARP). The study included 1477 consecutive patients treated with RARP by four surgeons between 2006 and 2014. UC recovery was defined as being completely dry over a 24-hour period at follow-up. Surgeon experience was coded as the total number of RARP performed by the surgeon before the patient's operation. Multivariable analysis tested the association between surgeon experience and UC recovery. Covariates consisted of patient age, Charlson comorbidity index, preoperative International Index of Erectile Function-Erectile Function domain (IIEF-EF), nerve-sparing surgery (none vs unilateral vs bilateral), and preoperative risk groups (low- vs intermediate- vs high risk). The number of cases performed by each surgeon was 541, 413, 411, and 112, respectively. Median follow-up was 24 months (inter-quartile range: 18, 40). The UC recovery rate at 1 year after surgery was 82%. At multivariable analyses, surgeon experience represented an independent predictor of UC recovery (hazard ratio: 1.02, p < 0.001). The surgical learning curve was similar among surgeons, moving linearly from ∼60% of UC rate at the initial cases to almost 90% after more than 400 procedures. In patients undergoing RARP, surgeon experience is a significant predictor of UC recovery. The surgical learning curve of UC recovery does not reach a plateau even after more than 100 cases, suggesting a continuous improvement of the surgical technique. These findings deserve attention for patient counseling and future comparative studies evaluating functional outcomes after RARP.

Although nerve-sparing robot-assisted radical prostatectomy (NS-RALP) is performed, a large number of patients still experience erectile dysfunction (ED) after surgery. To evaluate the efficacy and safety of tadalafil 5 mg once daily (OaD) in ED treatment over 2 years and investigate the cause of vascular ED after NS-RARP. We retrospectively evaluated 95 men who underwent NS-RARP and had a penile rehabilitation treatment with tadalafil 5 mg OaD. They were classified into 3 groups: tadalafil 5 mg OaD for 2 years (group I), tadalafil 5 mg OaD for 1 year (group II), and no tadalafil (group III). All patients in group I underwent penile color duplex ultrasound to evaluate the cause of vascular ED. Patients were surveyed using the abridged 5-item International Index of Erectile Function (IIEF-5). Statistically significant improvements were observed in group I for all IIEF-5 domain scores (P = .000). There was no statistically significant difference in recovery of erectile function (EF) the 2-year follow-up between groups I and II. Sub-analysis based on NS status showed no difference in recovery of EF. However, group I showed better trends in EF improvement. Those with venogenic ED had poor responses compared with those with arteriogenic ED or unremarkable findings with tadalafil 5-mg OaD treatment (14.2% vs 55.0% vs 53.3%). The overall side effects included hot flushing in 9.5%, headache in 7.1%, and dizziness in 2.3% of patients. Long-term usage of tadalafil 5 mg OaD after RARP can be an effective option for penile rehabilitation. The present study is a retrospective study with a relatively small sample. Although the responses of patients with venogenic ED were limited compared with those with arteriogenic ED, tadalafil 5-mg OaD treatment was well tolerated and significantly improved EF up to 2 years after NS-RARP.

Several experienced practitioners of open surgery with limited or no laparoscopic background have adopted robot-assisted laparoscopic radical prostatectomy (RLRP) as an alternative to open radical prostatectomy (RRP), demonstrating outcomes comparable to those in large RRP and laparoscopic prostatectomy series. Thus, the significance of prior laparoscopic skills seems unclear. The learning curve, with respect to operative time and complications, in the hands of a devoted laparoscopic surgeon has not been critically assessed. We evaluated the learning curve of a highly experienced laparoscopic surgeon in achieving expertise with RLRP. We prospectively evaluated 150 consecutive patients undergoing RLRP by a single surgeon between March 2003 and September 2005. The first 25 cases were performed with the assistance of a surgeon experienced in open RRP. Data were compared for the first, second, and third groups of 50 cases. Demographic data were similar for the three groups. Urinary and sexual function data were evaluated subjectively and objectively using the RAND-36v2 Survey and the UCLA PCI preoperatively and at 3, 6, and 12 months postoperatively. The mean operative time, blood loss, and conversion rate decreased significantly with increasing experience. All open conversions occurred during the first 25 cases. Intraoperative and postoperative complication rates were similar among groups. Although the differences were not significant, urinary and sexual function recovery improved with experience. The RLRP learning curve for a fellowship-trained laparoscopic surgeon seems to be similar to that of laparoscopically naive yet experienced practitioners of open RRP. The RLRP is safe and reproducible and even during the learning curve can produce results similar to those reported in large RRP series. The importance of assistance by an experienced open RRP surgeon during the learning curve cannot be overemphasized.

We examine the complication and continence rates with early catheter removal (day 3 or 4) after radical retropubic prostatectomy. A total of 365 patients with localized prostate cancer underwent radical retropubic prostatectomy at Indiana University Hospital with planned urethral catheter removal before discharge home. Low pressure cystograms were performed on postoperative day 3 or 4 to determine if catheter removal was possible. A subset of patients were analyzed using a validated prostate cancer specific questionnaire (University of California, Los Angeles Prostate Cancer Symptom Index) to determine quality of life outcomes. The catheter was removed on postoperative day 3 or 4 in 263 patients (72%). The reasons for leaving the catheter indwelling were significant leak on cystogram or excessive suprapubic drainage (21%), extensive bladder neck reconstruction (1%) and prolonged hospitalization because of an ileus or other complicating factor (6%). Thirteen patients (3.6%) were either unable to void after catheter removal or presented with retention (not associated with hematuria or clots) after hospital discharge, requiring reinsertion of the Foley catheter. A total of 41 patients (11%) had either an early or late complication (excluding incontinence). There were 3 complications (0.8%) that were considered major because they were potentially life threatening or required a return to the operating room. A pelvic abscess developed in 2 patients and a lymphocele in 1, which required percutaneous drainage. After at least 6 months (mean 20.9 months) 140 patients (89.2%) and 14 (8.9%) reported excellent and good continence, respectively. The patient questionnaire demonstrated bother scores to be minimal to no bother for 95% to 98% of patients at 6 and 12 months. This study confirms that it is safe to remove catheters in most patients 3 to 4 days after prostatectomy if a cystogram demonstrates no extravasation.

We have 3 options when perfoming prostatectomy for the treatment of localized prostate cancer. Those are retropubic radical prostatectomy, laparoscopic radical prostatectomy and robot-assisted laparoscopic radical prostatectomy. We compared the characteristics and results of these techniques. Robot-assisted laparoscopic radical prostatectomy could be superior to the others in many ways. However, it would be very difficult to adopt it in Japan because it would pose economical difficulties. The administrative assistance in the insurance systems requireds much more than we have.

We aimed to evaluate the risk factors of acute urinary retention (AUR) following robot-assisted radical prostatectomy (RARP), as well as the relationship of AUR with early continence outcomes. The records of 740 consecutive patients who underwent RARP by two experienced surgeons at our institution were retrospectively reviewed from a prospectively collected database. Multiple factors, including age, body mass index (BMI), international prostate symptom score (IPSS), prostate volume, presence of median lobe, nerve preservation status, anastomosis time, and catheter removal time (Day 4 vs. 7), were evaluated as risk factors for AUR using univariate and multivariate analysis. The relation between AUR and early return of continence (one and three months) post-RARP was also evaluated. The incidence of clinically significant vesico-urethral anastomotic (VUA) leak and AUR following catheter removal were 0.9% and 2.2% (17/740), respectively. In men who developed AUR, there was no significant relationship with regards to age, BMI, IPSS, prostatic volume, median lobe, nerve preservation, or anastomosis time; however, the incidence of AUR was significantly higher for men with catheter removal at Day 4 (4.5% [16/351]) vs. Day 7 (0.2% [1/389]) (p=0.004). Moreover, patients with early removal of the catheter (Day 4) who developed AUR had an earlier one-month return of 0-pad continence 87.5% (14/16) compared to patients without AUR 45.6% (153/335), with no significant difference at three months. While AUR is an uncommon complication of RARP, its incidence is much higher than VUA leakage. Further, it is often not well-discussed during patient counselling preoperatively. Moreover, earlier return of urinary continence was observed in patients experiencing AUR following RARP exclusively with catheter removal at Day 4. Future studies are warranted to validate the long-term impact of AUR on continence outcomes.

We compare urethrogram delineation of the caudal aspect of the anastomosis to the recommended guidelines of post prostatectomy radiotherapy. Level one evidence has established the indications for, and importance of, adjuvant radiotherapy following radical prostatectomy. Several guidelines have recently addressed delineation of the prostate bed target volume including identification of the vesico-urethral anastomosis, taken as the first CT slice caudal to visible urine in the bladder neck. The inferior border of clinical target volume is then variably defined 5-12 mm below this anastomosis or 15 mm cranial to the penile bulb. Thirty-three patients who received adjuvant radiotherapy following radical prostatectomy were reviewed. All underwent planning CT with urethrogram. The authors (MM, JC) independently identified the CT slice caudal to the last slice showing urine in the bladder neck (called the CT Reference Slice), and measured the distance between this and the tip of the urethrogram cone. Five patients also had a diagnostic MRI at the time of CT planning to better visualize the anatomy. Sixty-six readings were obtained. The mean distance between the Bladder CT Reference Slice and the most cranial urethrogram contrast slice was 16.1 mm (MM 16.4 mm, JC 15.8 mm), range: 6.8-34.2 mm. The mean distance between the urethrogram tip and the ischial tuberosities was 19.9 mm (range 12.5-29.8 mm). The mean distance between the CT Reference Slice and the ischial tuberosities was 36.9 mm (range 28.3-52.4 mm). Guidelines for prostate bed radiation post prostatectomy have been developed after publication of the trials proving benefit of such treatment, and are thus untested. The anastomosis is a frequent site of local relapse but is variably defined by the existing guidelines, none of which take into account anatomic patient variation and all of which are at variance with urethrogram data. We recommend the use of planning urethrogram to better delineate the vesico

To perform a contemporary comparative cost-analysis of robotic-assisted laparoscopic radical prostatectomy (RARP) and open radical retropubic prostatectomy (RRP). All patients undergoing RARP (n = 115) or RRP (n = 358) by 1 of 4 surgeons at a single institution during a 15-month period were retrospectively reviewed. The hospital length of stay (LOS), operative time, hospital charges, reimbursement, and direct and indirect hospital costs were analyzed and compared. The mean LOS between patients undergoing RARP (1.2 ± 0.6 days) and RRP (1.4 ± 0.8 days) was not significantly different. The operating room supply costs per case were almost 7 times greater for RARP ($2852 ± $528) than for RRP ($417 ± $59; P < .05). The ancillary, cardiology, imaging, administrative, laboratory, and pharmacy costs were not significantly different between the 2 approaches. The mean total costs per case for RARP exceeded the total costs for RRP by 62% ($14 006 ± $1641 vs $8686 ± $1989; P < .05). Payment to the hospital from all sources was nearly equivalent: $10 011 for RRP and $9993 for RARP. Therefore, the average profit for each RRP was $1325 and each RARP lost $4013. In the present single-institution analysis, the total actual costs associated with RARP were significantly greater than those for RRP and were attributable to the robotic equipment and supplies.

Robot-assisted laparoscopic radical prostatectomy (RALP) is an evolving minimally invasive treatment of for localized prostate cancer. We present our experience of 1500 consecutive cases with an analysis of perioperative outcomes. Fifteen hundred consecutive RALPs were performed by a single surgeon (VRP). Following Institutional Review Board approval, clinical coordinators performed prospective intraoperative and postoperative data collection. Functional outcomes were assessed using validated self-administered questionnaires. Mean OR time from skin incision to fascial closure (the time that the surgeon was present) was 105 minutes (55-300). Mean EBL was 111 cc (50-500). Ninety-seven percent of patients were discharged home on postoperative day 1. The overall complication rate was 4.3% with no mortalities. The positive margin rate (PMR) was 9.3% overall. PMR was 4% for pT2, 34% for T3 and 40% for pathologic stage T4. Our initial series represents one of the largest published series for perioperative outcomes of robotic assisted prostatectomy. Our data demonstrates the feasibility, safety and efficacy of the procedure.

Prostate cancer is commonly diagnosed in men worldwide. Surgery, in the form of radical prostatectomy, is one of the main forms of treatment for men with localised prostate cancer. Prostatectomy has traditionally been performed as open surgery, typically via a retropubic approach. The advent of laparoscopic approaches, including robotic-assisted, provides a minimally invasive alternative to open radical prostatectomy (ORP). To assess the effects of laparoscopic radical prostatectomy or robotic-assisted radical prostatectomy compared to open radical prostatectomy in men with localised prostate cancer. We performed a comprehensive search using multiple databases (CENTRAL, MEDLINE, EMBASE) and abstract proceedings with no restrictions on the language of publication or publication status, up until 9 June 2017. We also searched bibliographies of included studies and conference proceedings. We included all randomised controlled trials (RCTs) with a direct comparison of laparoscopic radical prostatectomy (LRP) and robotic-assisted radical prostatectomy (RARP) to ORP, including pseudo-RCTs. Two review authors independently classified studies and abstracted data. The primary outcomes were prostate cancer-specific survival, urinary quality of life and sexual quality of life. Secondary outcomes were biochemical recurrence-free survival, overall survival, overall surgical complications, serious postoperative surgical complications, postoperative pain, hospital stay and blood transfusions. We performed statistical analyses using a random-effects model and assessed the quality of the evidence according to GRADE. We included two unique studies with 446 randomised participants with clinically localised prostate cancer. The mean age, prostate volume, and prostate-specific antigen (PSA) of the participants were 61.3 years, 49.78 mL, and 7.09 ng/mL, respectively. Primary outcomes We found no study that addressed the outcome of prostate cancer-specific survival. Based on data from one

Background: There are significant post-surgical reductions in health-related quality of life (HRQOL) in prostate cancer (PCa) patients undergoing radical prostatectomy (RP). Physical activity (PA) interventions have improved treatment outcomes for PCa patients undergoing radiation and hormone therapy, but PA effects have not previously been examined in the RP setting. This study examined the relationship between preoperative PA levels and postoperative HRQOL outcomes in PCa patients treated with RP. Methods: Sixty patients were interviewed regarding lifetime PA and completed preoperative (2 weeks prior to surgery) and postoperative (4 weeks after surgery) HRQOL questionnaires. Aerobic fitness testing was conducted on a subsample of 22 patients. Results: Higher levels of total past-year PA and occupational PA significantly correlated with lesser HRQOL declines from presurgery to 4 weeks post-surgery (Beta = −0.364, p = 0.037 and Beta = −0.243, p = 0.089, respectively) in models adjusted for age, postoperative questionnaire completion date, Gleason score and education. Past-year occupational PA was highly positively correlated with past-year total PA (r = 0.785, p < 0.001). Lifetime total PA was correlated with estimated VO2 max (r = 0.486, p = 0.026) in the 22 patients who were aerobically tested. Lifetime and past-year PA volumes were not correlated with waist circumference or body mass index. Interpretation: Declines in HRQOL after RP may be reduced in patients with higher preoperative levels of self-reported PA. These findings require further study with larger samples to confirm results. If confirmed, findings suggest exercise preoperatively may improve HRQOL outcomes after RP. PMID:20514281

A publication on behalf of the European Society of Urological Oncology questioned the need for removing the seminal vesicles during radical prostatectomy in patients with prostate specific antigen less than 10 ng/ml except when biopsy Gleason score is greater than 6 or there are greater than 50% positive biopsy cores. We applied the European Society of Urological Oncology algorithm to an independent data set to determine its predictive value. Data on 1,406 men who underwent radical prostatectomy and seminal vesicle removal between 1998 and 2004 were analyzed. Patients with and without seminal vesicle invasion were classified as positive or negative according to the European Society of Urological Oncology algorithm. Of 90 cases with seminal vesicle invasion 81 (6.4%) were positive for 90% sensitivity, while 656 of 1,316 without seminal vesicle invasion were negative for 50% specificity. The negative predictive value was 98.6%. In decision analytic terms if the loss in health when seminal vesicles are invaded and not completely removed is considered at least 75 times greater than when removing them unnecessarily, the algorithm proposed by the European Society of Urological Oncology should not be used. Whether to use the European Society of Urological Oncology algorithm depends not only on its accuracy, but also on the relative clinical consequences of false-positive and false-negative results. Our threshold of 75 is an intermediate value that is difficult to interpret, given uncertainties about the benefit of seminal vesicle sparing and harm associated with untreated seminal vesicle invasion. We recommend more formal decision analysis to determine the clinical value of the European Society of Urological Oncology algorithm.

Robust biomarkers that identify prostate cancer patients with high risk of recurrence will improve personalised cancer care. In this study, we investigated whether tissue metabolites detectable by high-resolution magic angle spinning magnetic resonance spectroscopy (HR-MAS MRS) were associated with recurrence following radical prostatectomy. We performed a retrospective ex vivo study using HR-MAS MRS on tissue samples from 110 radical prostatectomy specimens obtained from three different Norwegian cohorts collected between 2002 and 2010. At the time of analysis, 50 patients had experienced prostate cancer recurrence. Associations between metabolites, clinicopathological variables, and recurrence-free survival were evaluated using Cox proportional hazards regression modelling, Kaplan-Meier survival analyses and concordance index (C-index). High intratumoural spermine and citrate concentrations were associated with longer recurrence-free survival, whereas high (total-choline+creatine)/spermine (tChoCre/Spm) and higher (total-choline+creatine)/citrate (tChoCre/Cit) ratios were associated with shorter time to recurrence. Spermine concentration and tChoCre/Spm were independently associated with recurrence in multivariate Cox proportional hazards modelling after adjusting for clinically relevant risk factors (C-index: 0.769; HR: 0.72; P=0.016 and C-index: 0.765; HR: 1.43; P=0.014, respectively). Spermine concentration and tChoCre/Spm ratio in prostatectomy specimens were independent prognostic markers of recurrence. These metabolites can be noninvasively measured in vivo and may thus offer predictive value to establish preoperative risk assessment nomograms.

We compared biochemical recurrence between men on active surveillance who underwent radical prostatectomy triggered by grade reclassification and men diagnosed with similar grade disease treated with immediate radical prostatectomy. We retrospectively analyzed the records of men who underwent surgery from 1995 to 2015 at our institution. We identified 4 groups, including 94 and 56 men on active surveillance who underwent radical prostatectomy following reclassification to Gleason 7 (3 + 4) or greater (grade groups 2 or greater) and Gleason 7 (3 + 4) (grade group 2), and 3,504 and 1,979 in the immediate prostatectomy group diagnosed with grade group 2 or greater and 2, respectively. Biochemical recurrence was assessed by Kaplan-Meir analysis and a multivariable Cox model. Men on active surveillance had a lower incidence of biochemical recurrence than men in the immediate radical prostatectomy groups for biopsy grade groups 2 or greater and 2 (each p <0.05). One, 5 and 10-year biochemical recurrence-free survival for men in the active surveillance group vs the immediate radical prostatectomy group was 97.9% vs 85.5%, 76.6% vs 65.1% and 69.0% vs 54.2% in biopsy grade groups 2 or greater (p = 0.009) and 96.4% vs 91.2%, 89.6% vs 74.0% and 89.6% vs 63.9%, respectively, in biopsy grade group 2 (p = 0.071). For biopsy grade groups 2 or greater there was no significant difference in the risk of biochemical recurrence between the groups after adjusting for age, biopsy extent of cancer and prostate specific antigen density. Patients on active surveillance reclassified to grade groups 2 or greater are at no greater risk for treatment failure than men newly diagnosed with similar grades.

Our present understanding of the effect of robotic surgery and surgical volume on the cost of radical prostatectomy (RP) is limited. Given the increasing pressures placed on healthcare resource utilization, such determinations of healthcare value are becoming increasingly important. Therefore, we performed a study to define the effect of robotic technology and surgical volume on the cost of RP. The state of Maryland mandates that all acute-care hospitals report encounter-level and hospital discharge data to the Health Service Cost Review Commission (HSCRC). The HSCRC was queried for men undergoing RP between 2008 and 2011 (the period during which robot-assisted laparoscopic radical prostatectomy [RALRP] was coded separately). High-volume hospitals were defined as >60 cases per year, and high-volume surgeons were defined as >40 cases per year. Multivariate regression analysis was performed to evaluate whether robotic technique and high surgical volume impacted the cost of RP. There were 1499 patients who underwent RALRP and 2565 who underwent radical retropubic prostatectomy (RRP) during the study period. The total cost for RALRP was higher than for RRP ($14,000 vs 10,100; P<0.001) based primarily on operating room charges and supply charges. Multivariate regression demonstrated that RALRP was associated with a significantly higher cost (β coeff 4.1; P<0.001), even within high-volume hospitals (β coeff 3.3; P<0.001). High-volume surgeons and high-volume hospitals, however, were associated with a significantly lower cost for RP overall. High surgeon volume was associated with lower cost for RALRP and RRP, while high institutional volume was associated with lower cost for RALRP only. High surgical volume was associated with lower cost of RP. Even at high surgical volume, however, the cost of RALRP still exceeded that of RRP. As robotic surgery has come to dominate the healthcare marketplace, strategies to increase the role of high-volume providers may be needed to

We set out to evaluate outcomes in patients over 74 after robotic radical prostatectomy. Six hundred forty-seven patients over 74 (≥75) were analyzed for preoperative factors (body mass index [BMI], American Society of Anestesiologists classification [ASA], prostate-specific antigen [PSA], International prostate symptome score [IPSS], International index of erectile function [IIEF]), operative and perioperative characteristics (technique, erythrocyte conc., complications), and histopathological results. After 12 months, following items were assessed: PSA, frequency of urine loss, number of pads used (including safety), incontinence at night, and potency as quantified by IIEF-5. Mean age in the group <75 was 64.8 years (range 46-74 years) and in the group ≥75 76.9 years (75-88). No statistically significant differences could be detected in terms of BMI, ASA score, or preoperative PSA, respectively. IPSS and IIEF were significantly worse in the group ≥75. Major complications (>Clavien-Dindo III) were found in 1.6% vs. 1.3% (≥75) of cases. Minor complications were encountered in 22.8% vs. 26.3% (≥75). There was a remarkably high percentage of locally advanced disease (73.3% vs. 71.0%) in both groups. Patients ≥75 showed a tendency toward more aggressive cancer and more frequent nodal involvement; we found a higher percentage of R1-resections (19.5% vs. 30.4%, p < 0.05) and PSA relapse after 1 year (12.3% vs. 22.8%, p < 0.05). Twelve months pad-free continence rate (69.9% vs. 63.2%) showed no statistically significant difference between both groups as did the preservation rate of erectile function. We could show that robotic prostatectomy can be carried out safely with good functional and histopathological results in patients ≥75. It is therefore questionable if elderly patients can be precluded from curative radical treatment solely because of their age.

To report the 5-year oncological outcomes of robot-assisted radical prostatectomy from the largest series ever reported from Asia. A retrospective analysis of 800 Asian patients who were treated with robot-assisted radical prostatectomy from July 2005 to May 2010 in the Department of Urology and Urological Science Institute, Yonsei University College of Medicine, Seoul, Korea was carried out. The primary end-point was to evaluate the biochemical recurrence. The secondary end-point was to show the biochemical recurrence-free survival, metastasis-free survival and cancer-specific survival. A total of 197 (24.65%), 218 (27.3%), and 385 (48.1%) patients were classified as low-, intermediate- and high-risk patients according to the D'Amico risk stratification risk criteria, respectively. The median follow-up period was 64 months (interquartile range 28-71 months). The overall incidence of positive surgical margin was 36.6%. There was biochemical recurrence in 183 patients (22.9%), 38 patients (4.8%) developed distant metastasis and 24 patients (3%) died from prostate cancer. Actuarial biochemical recurrence-free survival, metastasis-free survival, and cancer-specific survival rates at 5 years were 76.4%, 94.6% and 96.7%, respectively. Positive lymph node was associated with lower 5-year biochemical recurrence-free survival (9.1%), cancer-specific survival (75.7%) and metastasis-free survival (61.9%) rates (P < 0.001). On multivariable analysis, among all the predictors, positive lymph node was the strongest predictor of biochemical recurrence, cancer-specific survival and metastasis-free survival (P < 0.001). Herein we report the largest robot-assisted radical prostatectomy series from Asia. Robot-assisted radical prostatectomy is confirmed to be an oncologically safe procedure that is able to provide effective 5-year cancer control, even in patients with high-risk disease. © 2016 The Japanese Urological Association.

Several staging tools have been developed for open radical prostatectomy (ORP) patients. However, the validity of these tools has never been formally tested in patients treated with robot-assisted laparoscopic radical prostatectomy (RALP). We tested the accuracy of an ORP-derived nomogram in predicting the rate of extracapsular extension (ECE) in a large RALP cohort. Serum prostate specific antigen (PSA) and side-specific clinical stage and biopsy Gleason sum information were used in a previously validated nomogram predicting side-specific ECE. The nomogram-derived predictions were compared with the observed rate of ECE, and the accuracy of the predictions was quantified. Each prostate lobe was analyzed independently. As complete data were available for 576 patients, the analyses targeted 1152 prostate lobes. Median age and serum PSA concentration at radical prostatectomy were 60 years and 5.4 ng/mL, respectively. The majority of side-specific clinical stages were T(1c) (993; 86.2%). Most side-specific biopsy Gleason sums were 6 (572; 49.7%). The median side-specific percentages of positive cores and of cancer were, respectively, 20.0% and 5.0%. At final pathologic review, 107 patients (18.6%) had ECE, and side-specific ECE was present in 117 patients (20.3%). The nomogram was 89% accurate in the RALP cohort v 84% in the previously reported ORP validation. The ORP side-specific ECE nomogram is highly accurate in the RALP population, suggesting that predictive and possibly prognostic tools developed in ORP patients may be equally accurate in their RALP counterparts.

The long-term biochemical relapse-free survival and overall survival were compared for patients receiving either radiotherapy (RT) alone or radiotherapy combined with a short-course of total androgen suppression for failure after radical prostatectomy. Between 1985 and 2001, a total of 122 patients received RT after radical prostatectomy at our institution. Fifty-three of these patients received a short-course of total androgen suppression (TAS) 2 months before and 2 months concurrent with RT with a nonsteroidal antiandrogen and an luteinizing hormone-releasing hormone (LHRH) agonist (combined therapy group); the remaining 69 patients received RT alone. Treatment failure was defined after postoperative RT as a detectable PSA >0.05 ng/mL. Clinical and treatment variables examined included: presurgical PSA, clinical T stage, pathologic Gleason sum (pGS), seminal vesicle (SV) involvement, lymph node involvement, surgical margins, pre-RT PSA, prostate dose, pelvic irradiation, indication for postoperative RT (salvage or adjuvant), and time interval between surgery and RT. Minimum follow-up after postoperative RT was 1 year and median follow-up was 5.9 years (maximum, 14 years) for patients receiving RT alone, and 3.9 years (maximum, 11 years) for patients receiving RT with TAS (combined therapy group). Kaplan-Meier analysis was performed for PSA failure-free survival (bNED) and for overall survival (OS). Cox proportional hazards multivariable analysis examined the influence all clinical and treatment variables predicting for bNED and OS. The median time to PSA failure after postoperative RT was 1.34 years for the combined therapy group and 0.97 years for the RT alone group (p = 0.19), with no failures beyond 5 years. At 5 years, the actuarial bNED rates were 57% for the combined therapy group compared with 31% for the RT alone group (p = 0.0012). Overall survival rates at 5 years were 100% for the combined therapy group compared with 87% for the RT alone group (p = 0

Recent studies have demonstrated associations between ABO blood groups and prognosis in various types of cancers. The aim of this study was to investigate the association between ABO blood groups and biochemical recurrence (BCR) after radical prostatectomy (RP). A total of 555 patients with prostate cancer who underwent RP were included in the study. No patients received neoadjuvant and/or adjuvant therapy. The effect of ABO blood groups on BCR was examined using univariate and multivariate analyses. During the follow-up period (mean, 52.0 months), 166 patients (29.9%) experienced BCR, with a 5-year BCR-free rate of 67.3%. Although the ABO blood group was not a significantly associated with BCR in the univariate analysis, it was an independent predictor of BCR in the multivariate analysis: blood type O patients had a significantly lower risk of BCR compared to type A patients (Hazard ratio, 0.608; 95% confidence interval, 0.410-0.902; P = 0.014). Further analyses revealed that surgical margin status confounded the assessment of the association between the ABO blood group and BCR. In the analyses of patients with a negative surgical margin, the 5-year BCR-free rate in blood type O patients was a significantly higher than that in type A patients (91.2% vs. 71.0%; P = 0.026). Blood type O is significantly associated with a decreased risk of biochemical recurrence after radical prostatectomy. Further studies are needed to clarify the nature of this association.

Patients with high-risk prostate cancer have historically been treated with multimodal therapy and considered poor candidates for minimally invasive surgery. We reviewed our experiences with robot-assisted radical prostatectomy (RARP) in patients with high-risk clinical features. Clinical database review identified high-risk patients undergoing RARP by two high-volume robotic surgeons. D'Amico's criteria for high-risk prostate cancer were utilized: prostate-specific antigen ≥ 20 ng/mL, clinical stage ≥ T2c, or preoperative Gleason grade ≥ 8. About 148 patients were identified in the study group. Mean age at surgery was 60.9 years, and mean body mass index was 27.9. Mean estimated blood loss was 150 cc and the transfusion rate was 2.7%. Median hospital stay was 1 day and the rate of major complications (Clavien grade ≥ 3) was 3.4%. Bilateral nerve preservation was feasible in 28.4%, and the rate of positive surgical margins was 20.9%. Final pathology demonstrated extra-capsular disease in 54.1% of patients and 12.3% had lymph node involvement. At 2 years of follow-up, 21.3% of patients had experienced biochemical recurrence or had persistent disease after treatment. Continence was 91.2% (1 pad or less) and total impotence (inability to masturbate) was 48.3%. RARP does not compromise oncologic or functional outcomes in patients with high-risk prostate cancer. Although long-term study is necessary to validate oncologic and functional outcomes, our data suggest that the presence of high-risk disease is not a contraindication to a minimally invasive approach for radical prostatectomy at experienced centers.

To develop a nomogram for predicting side-specific extracapsular extension (ECE) for planning nerve-sparing radical prostatectomy. We retrospectively analysed data from 561 patients who underwent robot-assisted radical prostatectomy between February 2014 and October 2015. To develop a side-specific predictive model, we considered the prostatic lobes separately. Four variables were included: prostate-specific antigen; highest ipsilateral biopsy Gleason grade; highest ipsilateral percentage core involvement; and ECE on multiparametric magnetic resonance imaging (mpMRI). A multivariable logistic regression analysis was fitted to predict side-specific ECE. A nomogram was built based on the coefficients of the logit function. Internal validation was performed using 'leave-one-out' cross-validation. Calibration was graphically investigated. The decision curve analysis was used to evaluate the net clinical benefit. The study population consisted of 829 side-specific cases, after excluding negative biopsy observations (n = 293). ECE was reported on mpMRI and final pathology in 115 (14%) and 142 (17.1%) cases, respectively. Among these, mpMRI was able to predict ECE correctly in 57 (40.1%) cases. All variables in the model except highest percentage core involvement were predictors of ECE (all P ≤ 0.006). All variables were considered for inclusion in the nomogram. After internal validation, the area under the curve was 82.11%. The model demonstrated excellent calibration and improved clinical risk prediction, especially when compared with relying on mpMRI prediction of ECE alone. When retrospectively applying the nomogram-derived probability, using a 20% threshold for performing nerve-sparing, nine out of 14 positive surgical margins (PSMs) at the site of ECE resulted above the threshold. We developed an easy-to-use model for the prediction of side-specific ECE, and hope it serves as a tool for planning nerve-sparing radical prostatectomy and in the reduction of PSM in

To examine how surgical robot emergence affects prostate-cancer patient behavior in seeking radical prostatectomy focusing on geographical accessibility. In Japan, robotic surgery was approved in April 2012. Based on data in the Japanese Diagnosis Procedure Combination database between April 2012 and March 2014, distance to nearest surgical robot and interval days to radical prostatectomy (divided by mean interval in 2011: % interval days to radical prostatectomy) were calculated for individual radical prostatectomy cases at non-robotic hospitals. Caseload changes regarding distance to nearest surgical robot and robot introduction were investigated. Change in % interval days to radical prostatectomy was evaluated by multivariate analysis including distance to nearest surgical robot, age, comorbidity, hospital volume, operation type, hospital academic status, bed volume and temporal progress. % Interval days to radical prostatectomy became wider for distance to nearest surgical robot <30 km. When a surgical robot emerged within 30 and 10 km, the prostatectomy caseload in non-robot hospitals reduced by 13 and 18% within 6 months, respectively, while the robot hospitals gained +101% caseload (P < 0.01 for all) Multivariate analyses including 9759 open and 5052 non-robotic minimally invasive radical prostatectomies in 483 non-robot hospitals revealed a significant inverse association between distance to nearest surgical robot and % interval days to radical prostatectomy (B = -17.3% for distance to nearest surgical robot ≥30 km and -11.7% for 10-30 km versus distance to nearest surgical robot <10 km), while younger age, high-volume hospital, open-prostatectomy provider and temporal progress were other significant factors related to % interval days to radical prostatectomy widening (P < 0.05 for all). Robotic surgery accessibility within 30 km would make patients less likely select conventional surgery. The nearer a robot was, the faster the caseload reduction was

Previous studies have demonstrated differences in surgical outcomes after radical prostatectomy based on ethnicity. We compared sexual and urinary outcomes in African-American (AA) patients 6 and 12 months after robot-assisted radical prostatectomy (RARP) with those of non-AA patients. We reviewed our RARP database at our institution for patients with at least 12 months of follow-up. Erectile function was defined using the University of California, Los Angeles Prostate Cancer Index as erections "firm enough for masturbation and foreplay" or "firm enough for intercourse," while urinary continence was defined as being "pad free." Only patients who were potent and pad free preoperatively were included in the analysis. Multivariate logistic regression was used to compare postoperative potency and urinary pad-free status between AA and non-AA patients while controlling for pertinent demographic, clinical, and pathologic variables. In the urinary continence analysis, 140 AA patients and 576 non-AA patients were included, compared with 105 AAs and 500 non-AA patients who were included in the analysis of sexual function. At 12 months postoperatively, a smaller proportion of AA patients were potent compared with non-AA patients (60% vs 76.4%, P=0.001). Similarly, we found a lower incidence of pad-free status for AA patients at 12 months postoperatively (55.7% vs 69.8%, P=0.039). Similar functional results were found at 6 months postoperatively for both analysis groups. AA men appear to have worse urinary and sexual outcomes at 12 months after RARP compared with non-AA patients. At 6 months, there is no statistically significant difference. Further, longer-term studies are needed to validate these results.

Overall 1 in 5 patients with prostate cancer has a positive family history. In this report we evaluated the association between family history and long-term outcomes following radical prostatectomy. Patients treated with radical prostatectomy were identified from a German registry, and separated into positive first-degree family history vs negative family history (strictly negative, requiring at least 1 male first-degree relative older than 60 years and no prostate cancer in the family). Kaplan-Meier curves and Cox proportional hazards models were used for association analyses with biochemical recurrence-free and prostate cancer specific survival. Median followup for 7,690 men included in the study was 8.4 years. Of the 754 younger patients less than 55 years old 50.9% (384) had a family history compared to 40.4% of the older patients (2,803; p <0.001). The 10-year biochemical recurrence-free (62.5%) and prostate cancer specific survival (96.1%) rates did not differ between patients with vs without a family history, nor between the younger vs older patient groups (all p >0.05). Prostate specific antigen, pathological stage, node stage and Gleason score were the only significant predictors for biochemical recurrence-free survival, while pathological stage, node stage (all p <0.005) and Gleason score (Gleason 7 vs 6 or less-HR 1.711, 95% CI 1.056-2.774, p = 0.03; Gleason 8 or greater vs 6 or less-HR 4.516, 95% CI 2.776-7.347, p <0.0001) were the only predictors for prostate cancer specific survival. A family history of prostate cancer has no bearing on long-term outcomes after radical prostatectomy. Copyright © 2016 American Urological Association Education and Research, Inc.

Health related quality of life concerns factor prominently in prostate cancer management. We describe health related quality of life impact and recovery profiles of 4 commonly used operative treatments for localized prostate cancer. Beginning in February 2000 all patients treated with open radical prostatectomy, robot assisted laparoscopic prostatectomy, brachytherapy or cryotherapy were asked to complete the UCLA-PCI questionnaire before treatment, and at 3, 6, 12, 18, 24, 30 and 36 months after treatment. Outcomes were compared across treatment types with statistical analysis using univariate and multivariate models. A total of 785 patients treated between February 2000 and December 2008 were included in the analysis with a mean followup of 24 months. All health related quality of life domains were adversely affected by all treatments and recovery profiles varied significantly by treatment type. Overall urinary function and bother outcomes scored significantly higher after brachytherapy and cryotherapy compared to open radical prostatectomy and robotic assisted laparoscopic radical prostatectomy. Brachytherapy and cryotherapy had a 3-fold higher rate of return to baseline urinary function compared to open radical prostatectomy and robotic assisted laparoscopic radical prostatectomy. Sexual function and bother scores were highest after brachytherapy, with a 5-fold higher rate of return to baseline function compared to cryotherapy, open radical prostatectomy and robotic assisted laparoscopic radical prostatectomy. All 4 treatments were associated with relatively transient and less pronounced impact on bowel function and bother. In a study of sequential health related quality of life assessments brachytherapy and cryotherapy were associated with higher urinary function and bother scores compared to open radical prostatectomy and da Vinci prostatectomy. Brachytherapy was associated with higher sexual function and bother scores compared to open radical prostatectomy

To systematically assess the physicians' point of view of multimedia support in preoperative patient education for radical prostatectomy. We evaluated the view of physicians performing multimedia supported preoperative educations within a randomized controlled trial. Therein 8 physicians educated 203 patients for radical prostatectomy. All physicians rated multimedia supported education better than the standard procedure. Main reasons were better comprehensibility, the visual presentation, and greater ease in explaining complex issues. Objective time measurement showed no difference between both educations. The major disadvantage was the impression, that multimedia supported education lasted longer. Moreover, they had the impression that some details could be further improved. Given the choice, every physician would decide for multimedia support. Physicians appreciate multimedia support in preoperative education and contrary to their impression, multimedia support does not prolong patient education. Therefore, patients and physicians likewise profit from multimedia support for education and counseling. The readiness of physicians is a possible obstacle to this improvement, as their view is a key factor for the transition to everyday routine. Therefore, our results could alleviate this possible barrier for establishing multimedia supported education in clinical routine. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Urologists are cautious to offer minimally invasive radical prostatectomy in prostate cancer patients with high prostate-specific antigen (and therefore anticipated to have locally advanced or metastatic disease) because of concerns regarding lack of complete cure after minimally invasive radical prostatectomy and of worsening of continence if adjuvant radiotherapy is used. A retrospective review of our institutional database was carried out to identify patients with PSA ≥20 ng/mL who underwent minimally invasive radical prostatectomy between January 2002 and October 2010. Intraoperative, pathological, functional and short-term oncological outcomes were assessed. Overall, 233 patients met study criteria and were included in the analysis. The median prostate-specific antigen and prostate size were 28.5 ng/mL and 47 mL, respectively. Intraoperative complications were the following: rectal injury (0.86%) and blood transfusion (1.7%). Early postoperative complications included prolonged (>6 days) catheterization (9.4%), hematoma (4.7%), deep venous thrombosis (0.86%) and lymphocele (5.1%). Late postoperative complications included cerebrovascular accident (0.4%) and anastomotic stricture (0.8%). Pathology revealed poorly differentiated cancer in 48.9%, pT3/pT4 disease in 55.8%, positive margins in 28.3% and lymph node disease in 20.2% of the cases. Adverse pathological findings were more frequent in patients with prostate-specific antigen >40 ng/mL and (or) in those with locally advanced disease (pT3/pT4). In 62.2% of the cases, adjuvant radiotherapy was used. At 1-year follow up, 80% of patients did not show evidence of biochemical recurrence and 98.8% of them had good recovery of continence. Minimally invasive radical prostatectomy might represent a reasonable option in prostate cancer patients with high prostate-specific antigen as a part of a multimodality treatment approach. © 2012 The Japanese Urological Association.

Prostate cancer is an extremely prevalent cause of morbidity and mortality among American men. Several different treatments exist, but differences in utilization between these treatments are not well understood. We performed an observational study using administrative datasets linked to hospital survey data, which included non-metastatic prostate cancer patients receiving robot-assisted radical prostatectomy (RARP) or open radical prostatectomy (ORP) in California, Florida, or New York from 2009-2011. We developed two hierarchical regression models with fixed effect accounting for hospital clustering and physician clustering to determine factors associated with utilization of RARP versus ORP at hospitals offering robotic surgery. A total of 36,694 patients were identified, with 77.13% receiving RARP and 22.87% receiving ORP. African American patients had lower RARP rates than White patients (OR = 0.80, p < 0.001). Patients using Medicare (OR = 0.91, p = 0.028), Medicaid (OR = 0.68, p < 0.001), or self-pay (OR = 0.72, p = 0.046) had lower RARP rates than patients using private insurance. Patients in Florida had lower RARP rates than patients in California (OR = 0.48, p = 0.010). Patients treated at teaching hospitals had lower RARP rates than patients treated at non-teaching hospitals (OR = 0.50, p = 0.006). The average cost of RARP was $13,614.83, and the average cost of ORP was $12,167.44 (p < 0.001). This population based study suggests that both patient and hospital characteristics are associated with utilization of RARP versus ORP in hospitals where robotic surgery is offered.

To quantify complications to surgery in patients treated with robot-assisted radical prostatectomy (RARP) and open retropubic radical prostatectomy (RRP) at our institution. Radical prostatectomy is associated with specific complications that can affect outcome results in patients. Between January 2002 and August 2007, a series of 1738 consecutive patients underwent RARP (n = 1253) or RRP (n = 485) for clinically localized prostate cancer. Surgery-related complications were assessed using a prospective hospital-based complication registry. The baseline characteristics of all patients were documented preoperatively. Overall, 170 patients required blood transfusions (9.7%), 112 patients (23%) in the RRP group compared with 58 patients (4.8%) in the RARP group. Infectious complications occurred in 44 RRP patients (9%) compared with 18 (1%) in the RARP group. Bladder neck contracture was treated in 22 (4.5%) patients who had undergone RRP compared with 3 (0.2%) in the RARP group. Clavien grade IIIb-V complications were more common in RRP patients (n = 63; 12.9%) than in RARP patients (n = 46; 3.7%). The introduction of RARP at our institution has resulted in decreased number of patients with Clavien grade IIIb-V complications, such as bladder neck contractures, a decrease in the number of patients who require blood transfusions, and decreased numbers of patients with postoperative wound infections.

Cervical cancer is the most common cancer of the female reproductive system up to 20% of malignant tumors of the female genital organs. Surgery is the main method in treatment for local cervical cancer but postoperative complications often are associated with dysfunction of the pelvic organs. Some researchers focus their attention on the preservation of the pelvic innervation without loss of surgery's radicalism, which is represented in this survey. The paper presents the results of comparative analysis of 54 cases of surgical treatment for invasive cervical cancer.

Abstract Introduction: We set out to evaluate outcomes in patients over 74 after robotic radical prostatectomy. Materials and Methods: Six hundred forty-seven patients over 74 (≥75) were analyzed for preoperative factors (body mass index [BMI], American Society of Anestesiologists classification [ASA], prostate-specific antigen [PSA], International prostate symptome score [IPSS], International index of erectile function [IIEF]), operative and perioperative characteristics (technique, erythrocyte conc., complications), and histopathological results. After 12 months, following items were assessed: PSA, frequency of urine loss, number of pads used (including safety), incontinence at night, and potency as quantified by IIEF-5. Results: Mean age in the group <75 was 64.8 years (range 46–74 years) and in the group ≥75 76.9 years (75–88). No statistically significant differences could be detected in terms of BMI, ASA score, or preoperative PSA, respectively. IPSS and IIEF were significantly worse in the group ≥75. Major complications (>Clavien-Dindo III) were found in 1.6% vs. 1.3% (≥75) of cases. Minor complications were encountered in 22.8% vs. 26.3% (≥75). There was a remarkably high percentage of locally advanced disease (73.3% vs. 71.0%) in both groups. Patients ≥75 showed a tendency toward more aggressive cancer and more frequent nodal involvement; we found a higher percentage of R1-resections (19.5% vs. 30.4%, p < 0.05) and PSA relapse after 1 year (12.3% vs. 22.8%, p < 0.05). Twelve months pad-free continence rate (69.9% vs. 63.2%) showed no statistically significant difference between both groups as did the preservation rate of erectile function. Conclusion: We could show that robotic prostatectomy can be carried out safely with good functional and histopathological results in patients ≥75. It is therefore questionable if elderly patients can be precluded from curative radical treatment solely because of their age. PMID:29232985

To evaluate the diagnostic accuracy of conventional cystography for the detection of urine leakage at the vesicourethral anastomosis (VUA) site after radical prostatectomy based on computed tomography (CT) cystography. Patients who underwent radical prostatectomies at a single tertiary cancer centre were prospectively enrolled. Conventional cystography was routinely performed on postoperative day 7. Non-enhanced pelvic CT images were obtained after retrograde instillation of the same contrast material for a reference standard of urine leakage at the VUA site. Urine leakage was classified as follows: none; a plication abnormality; mild; moderate; and excessive. One hundred and twenty consecutive patients were enrolled. Conventional cystography detected 14 urine leakages, but CT cystography detected 40 urine leakages, which consisted of 28 mild and 12 moderate urine leakages. When using CT cystography as the standard measurement, conventional cystography showed a diagnostic accuracy of 17.8% (5/28) for mild urine leakage and 75% (9/12) for moderate leakage. Of nine patients diagnosed with mild leakage on conventional cystography, four (44.4%) had complicated moderate urine leakages based on CT cystography, requiring prolonged catheterization. The sensitivity, specificity, positive and negative predictive values, and accuracy of conventional cystography were 35, 100, 100, 75.4, and 78.3%, respectively. Conventional cystography is less accurate than CT cystography for diagnosing urine leakage at the VUA site after a radical prostatectomy. The present results suggest that CT cystography is a good choice for diagnostic imaging of urine leakage after radical prostatectomy. Copyright © 2010 The Royal College of Radiologists.

Although malformations of the genitourinary tract are typically identified during childhood, they can remain silent until incidental detection in evaluation and treatment of other pathologies during adulthood. The advent of the minimally invasive era in urologic surgery has given rise to unique challenges in the surgical management of anomalies of the genitourinary tract. This article reviews the embryology of anomalies of Wolffian duct (WD) derivatives with specific attention to the seminal vesicles, vas deferens, ureter, and kidneys. This is followed by a discussion of the history of the laparoscopic approach to WD derivative anomalies. Finally, we present two cases to describe technical considerations when managing these anomalies when encountered during robotic-assisted radical prostatectomy. The University of Chicago Robotic Laparoscopic Radical Prostatectomy (RLRP) database was reviewed for cases where anomalies of WD derivatives were encountered. We describe how modifications in technique allowed for completion of the procedure without difficulty. None Of the 1230 RLRP procedures performed at our institution by three surgeons, only two cases (0.16%) have been noted to have a WD anomaly. These cases were able to be completed without difficulty by making simple modifications in technique. Although uncommon, it is important for the urologist to be familiar with the origin and surgical management of WD anomalies, particularly when detected incidentally during surgery. Simple modifications in technique allow for completion of RLRP without difficulty.

To evaluate the occurrence of severe urinary complications within 2 years of surgery in men undergoing either robot-assisted radical prostatectomy (RARP), laparoscopic radical prostatectomy (LRP) or retropubic open radical prostatectomy (ORP). We conducted a population-based cohort study in men who underwent RARP (n = 4 947), LRP (n = 5 479) or ORP (n = 6 873) between 2008 and 2012 in the English National Health Service (NHS) using national cancer registry records linked to Hospital Episodes Statistics, an administrative database of admissions to NHS hospitals. We identified the occurrence of any severe urinary or severe stricture-related complication within 2 years of surgery using a validated tool. Multi-level regression modelling was used to determine the association between the type of surgery and occurrence of complications, with adjustment for patient and surgical factors. Men undergoing RARP were least likely to experience any urinary complication (10.5%) or a stricture-related complication (3.3%) compared with those who had LRP (15.8% any or 5.7% stricture-related) or ORP (19.1% any or 6.9% stricture-related). The impact of the type of surgery on the occurrence of any urinary or stricture-related complications remained statistically significant after adjustment for patient and surgical factors (P < 0.01). Men who underwent RARP had the lowest risk of developing severe urinary complications within 2 years of surgery. © 2017 The Authors BJU International published by John Wiley & Sons Ltd on behalf of BJU International.

Bladder neck contracture (BNC) after radical prostatectomy has been reported to occur in 5% to 32% of men after open radical retropubic prostatectomy (RRP) and 0% to 3% after laparoscopic RRP. Optimal anastomotic closure involves creating a watertight, tension-free anastomosis with well-vascularized, mucosal apposition and correct realignment of the urethra. The cause of BNC is poorly understood; however, it is likely related to multiple factors, including excessive luminal narrowing at the site of reconstruction, local tissue ischemia, failed mucosal apposition, and urinary leakage. In this large series of patients who underwent robot-assisted laparoscopic radical prostatectomy (RLRP), we report the incidence of BNC, evaluate the influence of age, body mass index (BMI), estimated blood loss (EBL), surgical time, and prostate weight on its development and assess follow-up urinary function. Between February 2003 and July 2006, 650 consecutive men underwent RLRP at our institution. Patients with aborted or open conversion procedures were excluded from analysis. The mean overall follow-up for the remaining 634 patients was 19.5 months. Patients presenting with symptoms of outlet obstruction were evaluated with cystoscopy to confirm a BNC. Comparisons of age, BMI, EBL, operative time, and prostate weight were performed using the Student t-test and chi-square analysis. BNC was the diagnosis in seven patients (1.1%), with a mean time of presentation of 4.8 (3-12) months postoperatively. The BNC patients had comparable mean age, BMI, prostate weight, and EBL to the non-BNC cohort. Their operative time, however, was significantly longer (283 v 225 min, P = 0.04). The incidence of BNC after radical prostatectomy is 1.1% in a large series of men undergoing RLRP. The diagnosis was made within 1 year. No significant impact on urinary continence or quality-of-life urinary function was observed after BNC management. A running anastomosis, better visualization, improved

Vesicourethral anastomotic urine leak is a common postoperative complication of radical prostatectomy. Herein we describe a novel method for the treatment of this complication. Intervention for a prolonged or massive anastomotic urine leak was required in 10 out of 1828 patients (0.5%) submitted to radical prostatectomy between 2007 and 2011. N-butyl-2-cyanoacrylate (Histoacryl) followed by fibrin glue (Greenplast) were injected under local anesthesia into vesicourethral anastomotic gaps under fluoroscopic guidance using a 20-Fr rigid cystoscope. Cystograms were taken in all patients to confirm complete urine leak resolution before the removal of the urethral catheter. Cystoscopic injection of Histoacryl followed by fibrin glue was technically successful and well tolerated in all patients. The mean time from radical prostatectomy to glue injection was 16.0 days (range 12-27 days). Urethral catheterization was required for an average of 7.7 days after cystoscopic injection of fibrin glue (range 3-13 days). These measures ultimately enabled complete resolution of the urine leak in all cases. At a mean follow up of 23.3 months, all 10 patients were fully continent. The mean time to recovery of urinary continence was 20.4 weeks (range 3.9-60.0 weeks). Cystoscopic injection of N-butyl-2-cyanoacrylate followed by fibrin glue into the anastomotic gap is both a feasible and effective solution in patients with a persistent or massive vesicourethral anastomotic urine leak after radical prostatectomy. © 2013 The Japanese Urological Association.

In the present study the authors assess the advantages of new technologies in thyroid surgery: to prevent nerve injury by using an intra-operative continuous nerve-monitoring techniques and to compare the real advantages of advanced coagulation devices. Among a series of 440 thyroidectomies (jan 2004-feb 2006) the Authors reviewed charts from two groups: (1) 240 total thyroidectomies performed using the traditional monopolar electrocautery, non-absorbable stitches for the principal vascular pedicles. (2) 140 total thyroidectomies performed using dedicated small bipolar electro thermal coagulator (ligasure-precise). (3) Since 2006 in a double blind group selection of 70, we've performed sutureless thyroidectomy with continuous intraoperative nerve monitoring using dedicated endotracheal tube. Mean operative time, post-operative bleeding, post-operative stay, incidence of transient or definitive laryngeal nerve lesions, incidence of permanent or transient hypocalcaemia, costs of the procedures were analyzed. Major complications in the first two groups compared with the data of the literature are absolutely over-imposable, except a reduction of incidence of transient hypocalcaemia in the Precise group, but if we compare data of the 3rd group (NIM), we find a significative reduction of transient and permanent laryngeal nerve palsy incidence. This new technology offers several advantages: (1) atraumatic; (2) easy to use; (3) continuous monitoring and audio feedback to the surgeon (4) works outside the operation field (5) high sensitiveness. Cost-analysis confirm that NIM + ligasure have same or less cost and time and probably less complications than traditional Total Thyroidectomy.

Objective To assess 90-day postoperative mortality after Robot assisted laparoscopic Radical prostatectomy (RARP) and retropubic radical prostatectomy (RRP) by use of nationwide population-based registry data. Patients and methods Cohort study in the National Prostate Cancer Register (NPCR) of Sweden of 22 344 men with prostate cancer in clinical local stage T1-T3, PSA <50 μg/ml who had undergone primary RP in 1998 - 2012. Vital status was ascertained through the Total Population Register. 90-day postoperative mortality was analysed by use of logistic regression analysis and comparison of 90-day mortality with the background population were made using standardised mortality ratios (SMR). Results 29 out of 14820 men (0.20%) died after RRP and 10 out of 7524 men (0.13%) died after RARP. Mortality during the 90-day postoperative period in the cohort was lower than in an age-matched background population, SMR 0.57 (CI 95% 0.39-0.75). There was no statistically significant difference in 90-day mortality according to surgical method, RARP vs. RRP (odds ratio, OR 1.14; 95% CI, 0.46-2.81). Postoperative 90-day mortality decreased over time, 2008-2012 vs. 1998-2007 (OR 0.44; 95% CI, 0.21-0.95), mainly due to decreased mortality after RARP. Limitations of our study include the non-randomised design and that more RARP were performed in recent years compared to RRP. Conclusion 90-day postoperative mortality was low after RARP and RRP and there was nostatistically significant difference between the methods. Given the long life expectancy among men with low and intermediate risk prostate cancer, very low postoperative mortality is a prerequisite for RP which was fulfilled by both RRP and RARP. The selection of healthy men for RP is highlighted by the lower 90-day mortality after RP compared to the background population. PMID:26762928

To evaluate the oncological profile and risk of biochemical recurrence of patients with prostate cancer who underwent radical prostatectomy based on the time period in which the patients were operated. To evaluate the differences in prostate-specific antigen (PSA) at diagnosis of patients with or without biochemical recurrence based on these time periods. Observation carried forward study of a cohort of 972 radical prostatectomies performed during 3 time periods (1994-2000, 2001-2006, 2007-2011). The importance of PSA at diagnosis on the time periods and on biochemical recurrence was assessed using a generalized linear model. The independent predictive behavior of biochemical recurrence was analyzed using Cox regression. The median follow-up was 38 (16-76) months. PSA levels at diagnosis were higher in the period 1994-2000 (12.97ng/mL, P<.001). Seventy-two percent of the patients from the period 2007-2011 were diagnosed as clinical stage T1c (P<.001), compared with 55% from the period 1994-2000. The percentage of extracapsular extension in the specimen decreased from 27% to 18% from the period 1994-2000 to the period 2007-2011 (p<.001). The percentage of patients with biochemical recurrence went from 38% to 14% from the first to the third period (P>.001). The difference between PSA levels at diagnosis for the patients with or without biochemical recurrence was independent of the period (P=.84). The period during which surgery was performed was not an independent predictive factor for biochemical recurrence (P=.09). Patients from the 2007-2011 period had less extracapsular disease in the radical prostatectomy. The period was not an independent predictive factor for biochemical recurrence. Copyright © 2014 AEU.

Identifying the optimal surgical approach for patients with localized prostate cancer (PCa) managed in the community setting remains controversial due to the lack of robust, prospective data. To assess surgical outcomes and changes in urinary and sexual quality of life (QOL) over time in patients undergoing radical prostatectomy (RP). Our study included patients enrolled in Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE), a large, prospective, mostly community-based, nationwide PCa registry, who underwent RP between 2004 and 2016. Open (ORP) versus robot-assisted radical prostatectomy (RARP) for localized PCa. Demographic and clinicopathologic data and surgical outcomes were compared between ORP and RARP. Self-reported, validated questionnaires (scaled 0-100 with higher numbers indicating better function) were used to evaluate urinary and sexual QOL at different time points. Repeated measures mixed-models assessed changes in function and bother over time in each domain. Among 1892 men (n = 1137 ORP; n = 755 RARP), Cancer of the Prostate Risk Assessment score, Gleason grade at biopsy and RP, and pT-stage were lower in ORP patients (all p < 0.01). Men undergoing RARP had comparable surgical margin rates, lymph node yields, and biochemical recurrence rates. In a subset analysis with 1451 men reporting baseline and follow-up QOL data, ORP patients reported superior scores in urinary incontinence (ORP mean ± standard deviation 69 ± 26 vs RARP 62 ± 27) and bother (ORP 75±29 vs RARP 68±28, both p < 0.01) only in the 1st yr after RP. Differences in sexual outcomes did not differ between groups, nor did any QOL scores beyond 1 yr. Limitations include a decrease in the rate of questionnaire response during follow-up, potential selection biases in terms of patient assignment to ORP versus RARP and survey completion rates, and the fact that RARP cases likely included the initial learning curve for the CaPSURE surgeons.

Laparoendoscopic single-site surgery (LESS) represents a novel approach to abdominal surgery. Several applications have already been described. Drawbacks include limited range of motion and need for articulated instruments. Robotic technology could overcome such technical difficulties. We report our experience with LESS radical prostatectomy (LESS-RP) in a cadaver and LESS robot-assisted radical prostatectomy (LESS-RARP) in a human patient. Standard laparoscopic instruments (SLI) and articulated laparoscopic instruments were used in the cadaveric LESS-RP. The da Vinci system was used in the LESS-RARP. Both procedures reproduced standard extraperitoneal laparoscopic prostatectomy as performed at Institut Montsouris. Control of the dorsal venous complex (DVC) and urethrovesical anastomosis (UVA) were key elements evaluated for feasibility. Cadaveric model: Total operative time (TOT) was 160 minutes, with 5 minutes for the DVC (one stitch) and 35 minutes for the UVA (six stitches). Although articulated instruments were helpful in the operation, SLI remained essential for the procedure. Clinical experience: LESS-RARP was performed for T(1c) prostate cancer. TOT was 150 minutes, including 5 minutes for the DVC (one figure-of-eight stitch) and 30 minutes for the UVA (six interrupted stitches). Blood loss was 500 mL. Bilateral neurovascular preservation was performed, and results of final pathologic examination showed negative surgical margins. The human cadaver is an adequate model for LESS-RP, and LESS-RARP is feasible to be performed in the clinical arena. The synergy of robotic technology and LESS represents a new generation of surgery.

The uterine fibroid pseudocapsule is a fibro-neurovascular structure surrounding a leiomyoma, separating it from normal peripheral myometrium. The fibroid pseudocapsule is composed of a neurovascular network rich in neurofibers similar to the neurovascular bundle surrounding a prostate. The nerve-sparing radical prostatectomy has several intriguing parallels to myomectomy. It may serve either as a useful model in modern fibroid surgical removal, or it may accelerate our understanding of the role of the fibrovascular bundle and neurotransmitters in the healing and restoration of reproductive potential after intracapsular myomectomy. Surgical innovations, such as laparoscopic or robotic myomectomy applied to the intracapsular technique with magnification of the fibroid pseudocapsule surrounding a leiomyoma, originated from the radical prostatectomy method that highlighted a careful dissection of the neurovascular bundle to preserve sexual functioning after prostatectomy. Gentle uterine leiomyoma detachment from the pseudocapsule neurovascular bundle has allowed a reduction in uterine bleeding and uterine musculature trauma with sparing of the pseudocapsule neuropeptide fibers. This technique has had a favorable impact on functionality in reproduction and has improved fertility outcomes. Further research should determine the role of the myoma pseudocapsule neurovascular bundle in the formation, growth, and pathophysiological consequences of fibroids, including pain, infertility, and reproductive outcomes.

Background Ipsilateral phrenic nerve blockade is a common adverse event after an interscalene brachial plexus block, which can result in respiratory deterioration in patients with preexisting pulmonary conditions. Diaphragm-sparing nerve block techniques are continuing to evolve, with the intention of providing satisfactory postoperative analgesia while minimizing hemidiaphragmatic paralysis after shoulder surgery. Case Report We report the successful application of a combined ultrasound-guided infraclavicular brachial plexus block and suprascapular nerve block in a patient with a complicated pulmonary history undergoing a total shoulder replacement. Conclusion This case report briefly reviews the important innervations to the shoulder joint and examines the utility of the infraclavicular brachial plexus block for postoperative pain management.

The aim of this work was to report our experience in robotic-assisted laparoscopic radical prostatectomy for the treatment of localized prostate cancer in a kidney transplant recipient. A 73-year-old man with chronic renal failure underwent living-donor kidney transplantation (KT) in 1993. His baseline creatinine after KT was ∼1.2 mg/dL. He developed lower urinary tract symptoms in 1999. He was diagnosed with benign prostatic hyperplasia and treated accordingly. He was followed regularly with the use of digital rectal examination and measurement of serum prostatic-specific antigen (PSA). In 2014, his serum PSA was 11.53 ng/mL. Prostate biopsy was done and revealed localized prostatic adenocarcinoma with a Gleason score of 7 (3+4). We performed robotic-assisted laparoscopic radical prostatectomy with the use of the Retzius space preservation technique. The patient underwent successful robotic-assisted laparoscopic radical prostatectomy without any complications. The operative time was 210 minutes with estimated blood loss of 250 mL. The patient tolerated the procedure well and was discharged on the 6th day after surgery with a retained Foley catheter. A cystogram was done on the 13th day after surgery and showed no urethrovesical anastomosis leakage. After Foley catheter removal, the patient could urinate normally without urinary incontinence. Pathologic analysis revealed positive surgical margin with no extraprostatic extension and no seminal vesical invasion. One month after the operation, PSA was 0.08 ng/mL and renal function remained stable. Robotic-assisted laparoscopic radical prostatectomy is technically feasible and safe for the treatment of localized prostate cancer in the renal transplant patient. The Retzius space preservation technique is helpful in minimizing the manipulation of transplanted kidney and urinary bladder during the operation, resulting in favorable postoperative renal function and continence outcome.

During 2008, the Royal Brisbane and Women's Hospital became the first public hospital in Australia to have a da Vinci Surgical Robot purchased by government funding. The cost of performing robotic surgery in the public sector is a contentious issue. This study is a single centre, cost analysis comparing open radical prostatectomy (RRP) and robotic-assisted radical prostatectomy (RALP) based on the newly introduced pure case-mix funding model. A retrospective chart review was performed for the first 100 RALPs and the previous 100 RRPs. Estimates of tangible costing and funding were generated for each admission and readmission, using the Royal Brisbane Hospital Transition II database, based on pure case-mix funding. The average cost for admission for RRP was A$13 605, compared to A$17 582 for the RALP. The average funding received for a RRP was A$11 781 compared to A$5496 for a RALP based on the newly introduced case-mix model. The average length of stay for RRP was 4.4 days (2-14) and for RALP, 1.2 days (1-4). The total cost of readmissions for RRP patients was A$70 487, compared to that of the RALP patients, A$7160. These were funded at A$55 639 and A$7624, respectively. RALP has shown a significant advantage with respect to length of stay and readmission rate. Based on the case-mix funding model RALP is poorly funded compared to its open equivalent. Queensland Health needs to plan on how robotic surgery is implemented and assess whether this technology is truly affordable in the public sector. © 2013 The Authors.

The pathology report of radical prostatectomy specimens plays an important role in clinical decisions and the prognostic evaluation in Prostate Cancer (PCa). The anatomical schema is a helpful tool to document PCa extension for clinical and research purposes. To achieve electronic documentation and analysis, an appropriate documentation model for anatomical schemas is needed. For this purpose we developed cMDX. The document architecture of cMDX was designed according to Open Packaging Conventions by separating the whole data into template data and patient data. Analogue custom XML elements were considered to harmonize the graphical representation (e.g. tumour extension) with the textual data (e.g. histological patterns). The graphical documentation was based on the four-layer visualization model that forms the interaction between different custom XML elements. Sensible personal data were encrypted with a 256-bit cryptographic algorithm to avoid misuse. In order to assess the clinical value, we retrospectively analysed the tumour extension in 255 patients after radical prostatectomy. The pathology report with cMDX can represent pathological findings of the prostate in schematic styles. Such reports can be integrated into the hospital information system. "cMDX" documents can be converted into different data formats like text, graphics and PDF. Supplementary tools like cMDX Editor and an analyser tool were implemented. The graphical analysis of 255 prostatectomy specimens showed that PCa were mostly localized in the peripheral zone (Mean: 73% ± 25). 54% of PCa showed a multifocal growth pattern. cMDX can be used for routine histopathological reporting of radical prostatectomy specimens and provide data for scientific analysis.

Chronic post-surgical pain (CPSP) by definition develops for the first time after surgery and is not related to any preoperative pain. Preoperative pain is assumed to be a major risk factor for CPSP. Prospective studies to endorse this assumption are missing. In order to assess the incidence and the risk factors for CPSP multidimensional pain and health characteristics and psychological aspects were studied in patients prior to radical prostatectomy. Follow-up questionnaires were completed three and six months after surgery. CPSP incidences in 84 patients after three and six months were 14.3% and 1.2%. Preoperatively, CPSP patients were assigned to higher pain chronicity stages measured with the Mainz Pain Staging System (MPSS) (p=0.003) and higher pain severity grades (Chronic Pain Grading Questionnaire) (p=0.016) than non-CPSP patients. CPSP patients reported more pain sites (p=0.001), frequent pain in urological body areas (p=0.047), previous occurrence of CPSP (p=0.008), more psychosomatic symptoms (Symptom Check List) (p=0.031), and worse mental functioning (Short Form-12) (p=0.019). Three months after surgery all CPSP patients suffered from moderate to high-risk chronic pain (MPSS stages II and III) compared to 66.7% at baseline and 82.3% had high disability pain (CPGQ grades III and IV) compared to 41.7% before surgery. CPSP patients scored significantly less favorably in physical and mental health, habitual well-being, and psychosomatic dysfunction three months after surgery. All patients with CPSP reported on preoperative chronic pain. Patients with preoperative pain, related or not related to the surgical site were significantly at risk to develop CPSP. High preoperative pain chronicity stages and pain severity grades were associated with CPSP. CPSP patients reported poorer mental health related quality of life and more severe psychosomatic dysfunction before and 3 months after surgery.

Penile length (PL) shortening is an underreported phenomenon following radical prostatectomy (RP) and risk factors are not fully explored. We aimed to describe longitudinal patterns of PL recovery and evaluate factors predicting complete return to baseline PL. PL measurement was performed during a preoperative and postoperative follow-up visits at 7 days and 3, 6, 9, and 12 months. Patients who completely recovered (CR: N = 397) their preoperative stretched PL measured during at least one of their follow-up visits were compared to those with incomplete recovery (IR: N = 131). Recovery patterns were analyzed for both groups and were also compared in regards to demographics, nerve-sparing techniques, prostate size, cardiovascular risk profiles, and phosphodiesterase-5 inhibitor (PDE5i) uses. Logistic regression analyses were performed using age and other relevant clinicopathologic variables to predict PL recovery. 60.2% of the total study population regained their preoperative PL at 12 months. Average percent (length) differences from baseline were - 1.70% (- 0.25 cm) and - 16.42% (- 2.35 cm) in the CR and the IR groups, respectively (p < 0.001). Multivariate logistic regression demonstrated that younger age (OR 0.962; 95%CI 0.931-0.994; p = 0.019), high preoperative erectile function (EF) (OR 1.028; 95%CI 1.001-1.056; p = 0.046), and consistent PDE5i use (OR 1.998; 95%CI 1.166-3.425; p = 0.012) were independent predictors of CR. At 12-month follow up, PL difference for consistent PDE5iusers was statistically different from those who did not use PDE5i consistently (- 3.25%vs. -6.64%; P = 0.001). Age, preoperative EF, and consistent use of PDE5i were associated with complete recovery of baseline PL after RP. The therapeutic effect of PDE5i was most pronounced at 12-month visit, suggesting an added benefit with long-term use.

IMPORTANCE Soy consumption has been suggested to reduce risk or recurrence of prostate cancer, but this has not been tested in a randomized trial with prostate cancer as the end point. OBJECTIVE To determine whether daily consumption of a soy protein isolate supplement for 2 years reduces the rate of biochemical recurrence of prostate cancer after radical prostatectomy or delays such recurrence. DESIGN, SETTING, AND PARTICIPANTS Randomized, double-blind trial conducted from July 1997 to May 2010 at 7 US centers comparing daily consumption of a soy protein supplement vs placebo in 177 men at high risk of recurrence after radical prostatectomy for prostate cancer. Supplement intervention was started within 4 months after surgery and continued for up to 2 years, with prostate-specific antigen (PSA) measurements made at 2-month intervals in the first year and every 3 months thereafter. INTERVENTION Participants were randomized to receive a daily serving of a beverage powder containing 20 g of protein in the form of either soy protein isolate (n=87)or, as placebo, calcium caseinate (n=90). MAIN OUTCOMES AND MEASURES Biochemical recurrence rate of prostate cancer (defined as development of a PSA level of ≥0.07 ng/mL) over the first 2 years following randomization and time to recurrence. RESULTS The trial was stopped early for lack of treatment effects at a planned interim analysis with 81 evaluable participants in the intervention group and 78 in the placebo group. Overall, 28.3% of participants developed biochemical recurrence within 2 years of entering the trial (close to the a priori predicted recurrence rate of 30%). Among these, 22 (27.2%) occurred in the intervention group and 23 (29.5%) in the placebo group. The resulting hazard ratio for active treatment was 0.96 (95% CI, 0.53–1.72; log-rank P = .89). Adherence was greater than 90% and there were no apparent adverse events related to supplementation. CONCLUSION AND RELEVANCE Daily consumption of a beverage

The CAPRA-S score predicts prostate cancer recurrence based on pathological information from radical prostatectomy. To our knowledge CAPRA-S has never been externally validated in a European cohort. We independently validated CAPRA-S in a single institution European database. The study cohort comprised 14,532 patients treated with radical prostatectomy between January 1992 and August 2012. Prediction of biochemical recurrence, metastasis and cancer specific mortality by CAPRA-S was assessed by Kaplan-Meier analysis and the c-index. CAPRA-S performance to predict biochemical recurrence was evaluated by calibration plot and decision curve analysis. Median followup was 50.8 months (IQR 25.0-96.0). Biochemical recurrence developed in 20.3% of men at a median of 21.2 months (IQR 7.7-44.9). When stratifying patients by CAPRA-S risk group, estimated 5-year biochemical recurrence-free survival was 91.4%, 70.4% and 29.3% in the low, intermediate and high risk groups, respectively. The CAPRA-S c-index to predict biochemical recurrence, metastasis and cancer specific mortality was 0.80, 0.85 and 0.88, respectively. Metastasis developed in 417 men and 196 men died of prostate cancer. The CAPRA-S score was accurate when applied in a European study cohort. It predicted biochemical recurrence, metastasis and cancer specific mortality after radical prostatectomy with a c-index of greater than 0.80. The score can be valuable in regard to decision making for adjuvant therapy. Copyright © 2015. Published by Elsevier Inc.

To assess the risk factors for biochemical recurrence in D'Amico intermediate-risk prostate cancer patients treated using radical prostatectomy. We retrospectively reviewed the medical records of 1268 men with prostate cancer treated using radical prostatectomy without neoadjuvant therapy. The association between various risk factors and biochemical recurrence was then statistically evaluated. The Kaplan-Meier method, log-rank tests and Cox proportional hazards models were used for statistical analysis. In the intermediate-risk group, 96 patients (14.5%) experienced biochemical recurrence during a median follow up of 41 months. In the intermediate-risk group, preoperative prostate-specific antigen level, prostate volume and prostate-specific antigen density were significant preoperative risk factors for biochemical recurrence, whereas other factors including age, primary Gleason 4, clinical stage >T2 and percentage of positive biopsies were not. In multivariate analysis, higher preoperative prostate-specific antigen level and density, and a smaller prostate volume were independent risk factors for biochemical recurrence in the intermediate-risk group. Biochemical recurrence-free survival of patients in the intermediate-risk group with a higher prostate-specific antigen level and density (≥15 ng/mL, ≥0.6 ng/mL/cm(3), respectively), and lower prostate volume (≤10 mL) was comparable with that of high-risk group individuals (P = 0.632, 0.494 and 0.961, respectively). Preoperative prostate-specific antigen, prostate volume and prostate-specific antigen density are significant risk factors for biochemical recurrence in D'Amico intermediate-risk prostate cancer patients treated using radical prostatectomy. Using these variables, a subset of the intermediate-risk patients can be identified as having equivalent outcomes to high-risk patients. © 2015 The Japanese Urological Association.

We sought to identify the clinical and magnetic resonance imaging variables predictive of biochemical recurrence after robotic assisted radical prostatectomy in patients who underwent multiparametric 3 Tesla prostate magnetic resonance imaging. We performed an institutional review board approved, HIPAA (Health Insurance Portability and Accountability Act) compliant, single arm observational study of 3 Tesla multiparametric magnetic resonance imaging prior to robotic assisted radical prostatectomy from December 2009 to March 2016. Clinical, magnetic resonance imaging and pathological information, and clinical outcomes were compiled. Biochemical recurrence was defined as prostate specific antigen 0.2 ng/cc or greater. Univariate and multivariate regression analysis was performed. Biochemical recurrence had developed in 62 of the 255 men (24.3%) included in the study at a median followup of 23.5 months. Compared to the subcohort without biochemical recurrence the subcohort with biochemical recurrence had a greater proportion of patients with a high grade biopsy Gleason score, higher preoperative prostate specific antigen (7.4 vs 5.6 ng/ml), intermediate and high D'Amico classifications, larger tumor volume on magnetic resonance imaging (0.66 vs 0.30 ml), higher PI-RADS® (Prostate Imaging-Reporting and Data System) version 2 category lesions, a greater proportion of intermediate and high grade radical prostatectomy Gleason score lesions, higher pathological T3 stage (all p <0.01) and a higher positive surgical margin rate (19.3% vs 7.8%, p = 0.016). On multivariable analysis only tumor volume on magnetic resonance imaging (adjusted OR 1.57, p = 0.016), pathological T stage (adjusted OR 2.26, p = 0.02), positive surgical margin (adjusted OR 5.0, p = 0.004) and radical prostatectomy Gleason score (adjusted OR 2.29, p = 0.004) predicted biochemical recurrence. In this cohort tumor volume on magnetic resonance imaging and pathological variables, including Gleason score

Barriers and enablers to the provision and receipt of preoperative pelvic floor muscle training for men having radical prostatectomy: a qualitative study

PubMed Central

2013-01-01

Background Strong evidence exists to support preoperative pelvic floor muscle training (PFMT) to reduce the severity and duration of urinary incontinence after radical prostatectomy. Receipt of preoperative PFMT amongst men having radical prostatectomy in Western Sydney, however, is suboptimal. This study was undertaken to investigate barriers and enablers to provision/receipt of preoperative PFMT from the perspectives of potential referrers to and providers of PFMT, and of men having radical prostatectomy. Methods A qualitative research design was used. Semi-structured, one-to-one interviews were conducted with participants from three groups: (i) current and potential referrers to PFMT, including urological cancer surgeons, urological cancer nurses and general practitioners (n = 11); (ii) current and potential providers of PFMT across public and private sector hospital and outpatient settings, including physiotherapists and continence nurses (n = 14); and (iii) men having had radical prostatectomy at a specific public and co-located private hospital in Western Sydney (n = 13). Interview schedules were developed using Michie’s theoretical domains for investigating the implementation of evidence-based practice, and allowed participants to identify potential and actual barriers and enablers to preoperative PFMT. Transcribed interview data were analysed using a framework approach, and key themes were identified. Results Participant groups concurred that a recommendation for PFMT from the urological cancer surgeon, accompanied with a referral to a specific provider, was a key enabler of preoperative PFMT. Perceived barriers varied between participant groups and across public and private healthcare settings. Perceptions of financial cost of private sector PFMT, limited knowledge amongst referrers of public sector providers of PFMT, and limited awareness amongst patients of the benefits of PFMT were all posited to contribute to suboptimal PFMT provision and

To evaluate the feasibility and functional urinary and digestive results of nerve sparing techniques in endometriosis surgery. A research on the medline/pubmed database using specific keywords (nerve sparing, endometriosis, pelvic nerves) identified 7 publications among about 50 whose purpose was to describe the feasibility, the techniques and the functional results of nerve preservation in this indication. Among them there are: 2 uncontrolled retrospective studies, 3 prospective non-randomized studies, a meta-analysis and a review of the literature. Nerve preservation requires a perfect knowledge of the anatomy of the pelvic autonomic system. The laparoscopic approach is preferred by the different authors due to its anatomical advantage. The feasibility of this technique seems to be demonstrated despite certain limitations in the different studies and depending of the retroperitoneal extension of the lesions. When feasible, it is likely to significantly improve postoperative urinary function (urinary retention) compared to a conventional technique. It is observed no difference regarding digestive function. Nerve sparing in this indication is a technique the feasibility of which has been demonstrated and is subject to the topography and extent of the disease. In the absence of invasion or entrapment of pelvic autonomic nerves by endometriosis, this technique improves postoperative voiding function (NP3). During pelvic surgery for endometriosis, it is recommended to identify and preserve autonomic pelvic nerves whenever possible (GradeC). Copyright © 2018. Published by Elsevier Masson SAS.

Blue nevus of the prostate: incidental finding in radical prostatectomy specimen with a pre-operative echographic image of peripheral hypoechogenic nodule.

2011-12-01

Blue nevus is a stromal melanin deposition, which is microscopically characterized by deeply pigmented melanin-filled spindle cells within the fibromuscular stroma. Cases with prominent melanosis such as those with grossly visible pigment are uncommon. Melanocytic lesions of the prostate are incidental findings with no evidence of malignant transformation. There have only been very few reports of a malignant melanoma of primary prostatic origin. We report an incidental finding of a blue nevus of the prostate, in a radical prostatectomy specimen, in a 64-years-old man with a pre-operative ecographic image of peripheral hypoechogenic nodule. The are very few reports of blue nevi associated to prostatic adenocarcinoma, but none has been evidentiated before surgery as a distinct ultrasound lesion interpreted as adenocarcinoma, therefore inducing the clinician to perform biopsies and consequently a radical prostatectomy.

Salvage cryotherapy: is there a role for focal therapy?

PubMed

Gowardhan, Bharat; Greene, Damian

2010-05-01

Prostate cancer treatment has undergone vast development over the last few decades, but the most notable changes have included nerve-sparing open radical prostatectomy, laparoscopic radical prostatectomy, including robot-assisted and, more recently, cryotherapy and high-intensity focused ultrasound (HIFU). While radical surgery is the current gold standard, the less invasive therapeutic options of cryotherapy and HIFU are regarded as largely experimental by governing bodies. In the case of cryotherapy, a wealth of experience has been accumulated demonstrating its efficacy. Initially used as a salvage treatment for radiation-failed prostate cancer, cryotherapy has been widely used as a primary treatment for localized and locally advanced prostate cancer. More recently, there has been interest expressed in the concept of focal therapy in prostate cancer. This has been evaluated as a primary treatment for prostate cancer, but little information is available regarding the potential use as a salvage treatment. In this article, we evaluate the potential for focal treatment in the salvage setting.

To The standard technique for obtaining a histologic diagnosis of prostatic carcinomas is transrectal ultrasound guided prostate biopsy. Acute prostatitis which might develop after prostate biopsy can cause periprostatic inflammation and fibrosis. In this study, we performed a retrospective review of our database to determine whether ABP history might affect the outcome of RP. 441 RP patients who were operated in our clinic from 2002 to 2014 were included in our study group. All patients' demographic values, PSA levels, biopsy and radical prostatectomy specimen pathology results and their perioperative/postoperative complications were evaluated. There were 41 patients in patients with acute prostatitis following biopsy and 397 patients that did not develop acute prostatitis. Mean blood loss, transfusion rate and operation period were found to be significantly higher in ABP patients. Hospitalization period and reoperation rates were similar in both groups. However, post-op complications were significantly higher in ABP group. Even though it does not affect oncological outcomes, we would like to warn the surgeons for potential complaints during surgery in ABP patients.

Bladder neck contracture (BNC) after radical prostatectomy has been reported to occur in 5% to 32% of men after open retropubic prostatectomy (RRP) and in 0% to 3% after laparoscopic RRP. Optimal anastomotic closure involves creating a watertight, tension-free anastomosis with well-vascularized, mucosal apposition and correct realignment of the urethra. The cause of BNC is poorly understood; however, it is likely related to multiple factors, including excessive luminal narrowing at the site of reconstruction, local tissue ischemia, failed mucosal apposition, and urinary leakage. In this large series of patients who underwent robot-assisted laparoscopic radical prostatectomy (RLRP), we report the incidence of BNC, evaluate the influence of age, body mass index (BMI), estimated blood loss (EBL), surgical time, and prostate weight on its development and assess follow-up urinary function. Between February 2003 and July 2006, 650 consecutive men underwent RLRP at our institution. Patients with aborted or open conversion procedures were excluded from analysis. The mean overall follow-up for the remaining 634 patients was 19.5 months. Patients presenting with symptoms of outlet obstruction were evaluated with cystoscopy to confirm a BNC. Comparisons of age, BMI, EBL, operative time, and prostate weight were performed using the Student t-test and chi-square analysis. BNC was the diagnosis in seven patients (1.1%) with a mean time of presentation of 4.8 (3-12) months postoperatively. The BNC patients had comparable mean age, BMI, prostate weight, and EBL to the non-BNC cohort. Their operative time, however, was significantly longer (283 v 225 min., P = 0.04). The incidence of BNC after radical prostatectomy is 2.2% in a large series of men undergoing RLRP. The diagnosis was made within 1 year. No significant impact on urinary continence or quality-of-life urinary function was observed after BNC management. A running anastomosis, better visualization, improved instrument

Clinical map document based on XML (cMDX): document architecture with mapping feature for reporting and analysing prostate cancer in radical prostatectomy specimens

PubMed Central

2010-01-01

Background The pathology report of radical prostatectomy specimens plays an important role in clinical decisions and the prognostic evaluation in Prostate Cancer (PCa). The anatomical schema is a helpful tool to document PCa extension for clinical and research purposes. To achieve electronic documentation and analysis, an appropriate documentation model for anatomical schemas is needed. For this purpose we developed cMDX. Methods The document architecture of cMDX was designed according to Open Packaging Conventions by separating the whole data into template data and patient data. Analogue custom XML elements were considered to harmonize the graphical representation (e.g. tumour extension) with the textual data (e.g. histological patterns). The graphical documentation was based on the four-layer visualization model that forms the interaction between different custom XML elements. Sensible personal data were encrypted with a 256-bit cryptographic algorithm to avoid misuse. In order to assess the clinical value, we retrospectively analysed the tumour extension in 255 patients after radical prostatectomy. Results The pathology report with cMDX can represent pathological findings of the prostate in schematic styles. Such reports can be integrated into the hospital information system. "cMDX" documents can be converted into different data formats like text, graphics and PDF. Supplementary tools like cMDX Editor and an analyser tool were implemented. The graphical analysis of 255 prostatectomy specimens showed that PCa were mostly localized in the peripheral zone (Mean: 73% ± 25). 54% of PCa showed a multifocal growth pattern. Conclusions cMDX can be used for routine histopathological reporting of radical prostatectomy specimens and provide data for scientific analysis. PMID:21078179

Intraoperative monitoring of the cranial nerve XI (CN XI) may decrease shoulder disability following modified radical neck dissection. Prospective study was designed comparing results of Constant Shoulder Score (CSS), Shoulder Pain and Disability Index (SPADI) and EMG score of the trapezius muscle (mT) before and after surgery. One side of the neck was monitored during surgery with intraoperative nerve monitor. EMG scores of the mT 6 months postoperatively were statistically better on monitored as compared to the non-monitored side of the neck (p = 0.041), while the differences of the CSS and SPADI were not statistically significant. Patients with better EMG scores of the mT at 6 weeks recuperated better and with smaller decrease of the CSS. Intraoperative monitoring is beneficial at the beginning of the surgeon's learning curve and in the process of familiarizing with anatomical variation of the CN XI.

Over the past decade, the introduction of robotics in the field of medicine has provided a new approach to patients requiring surgery, and both its advantages and disadvantages are currently under study by many groups worldwide. The use of robotics has especially been considered by the urological community as a treatment option in radical prostatectomy. The current case report is one in which the da Vinci Surgical System™, with fourth arm use was employed in radical prostatectomy. This case presents a unique occurrence in which a bolt of the Prograsper forcep became loose during an operation, leading to diminished device functionality and later impedance of its removal. A circumstance such as this has not previously been reported, so we introduce for other robotic surgeons our unique instrumental malfunction case during a robotic prostatectomy. PMID:20046531

To investigate the effects of oral carbohydrate solution consumed until 2 h before the surgery in the patients that would undergo open radical retropubic prostatectomy on postoperative metabolic stress, patient anxiety, and comfort. A total of 50 adult patients, who were in ASA I-II group and would undergo open radical retropubic prostatectomy, were included in the study. While Group 1 = CH (n = 25) received oral glucose solution, Group 2 = FAM (n = 25) was famished starting from 24:00 h. Blood glucose, insulin, and procalcitonin levels of the patients were recorded, and the patients completed state-trait anxiety inventory (STAI) test, which reflects the anxiety level of the patients, both before surgery and on the postoperative 24th hour. In order to evaluate patient comfort, senses of hunger, thirst, nausea, and cold were assessed in the morning prior to the surgery. No difference was observed between the two groups in terms of demographic data and insulin resistance levels (p > 0.05). Comparing with the preoperative levels, insulin resistance showed statistically significant elevation in both groups (p < 0.05). Procalcitonin levels were similarly increased in both groups in the postoperative period (p < 0.05). Preoperative and postoperative STAI state scores were similar in both groups (p > 0.05). With regard to preoperative patient comfort, sense of hunger was present in lesser number of subjects and at lower level in Group 1 (p < 0.05). Preoperative consumption of high carbohydrate drink (Pre-op) decreases insulin resistance and enhances patient comfort leading to lesser sense of hunger and thirst in the preoperative period in open radical retropubic prostatectomies.

The economic value of robotic-assisted laparoscopic prostatectomy (RALP) in the United States is still not well understood because of limited view analyses. The objective of this study was to examine the costs and benefits of RALP versus retropubic radical prostatectomy from an expanded view, including hospital, payer, and societal perspectives. We performed a model-based cost comparison using clinical outcomes obtained from a systematic review of the published literature. Equipment costs were obtained from the manufacturer of the robotic system; other economic model parameters were obtained from government agencies, online resources, commercially available databases, an advisory expert panel, and the literature. Clinical point estimates and care pathways based on National Comprehensive Cancer Network guidelines were used to model costs out to 3 years. Hospital costs and costs incurred for the patients' postdischarge complications, adjuvant and salvage radiation treatment, incontinence and potency treatment, and lost wages during recovery were considered. Robotic system costs were modeled in two ways: as hospital overhead (hospital overhead calculation: RALP-H) and as a function of robotic case volume (robotic amortization calculation: RALP-R). All costs were adjusted to year 2014 US dollars. Because of more favorable clinical outcomes over 3 years, RALP provided hospital ($1094 savings with RALP-H, $341 deficit with RALP-R), payer ($1451), and societal ($1202) economic benefits relative to retropubic radical prostatectomy. Monte-Carlo probabilistic sensitivity analysis demonstrated a 38% to 99% probability that RALP provides cost savings (depending on the perspective). Higher surgical consumable costs are offset by a decreased hospital stay, lower complication rate, and faster return to work.

Hem-o-lok clips are widely used during robot-assisted and laparoscopic radical prostatectomy to control the lateral pedicles. There are a few reports of hem-o-lok clip migration into the bladder or vesico-urethral anastomosis and only four cases of hem-o-lok clip migration resulting into bladder neck contracture. Herein, we describe the first case, to our knowledge, of hem-o-lok clip migration leading to severe bladder neck contracture and subsequent stress urinary incontinence. A 62-year-old Caucasian man underwent robot-assisted laparoscopic radical prostatectomy for a T1c Gleason 8 prostate cancer. One month after surgery the patient was fully continent; however, three months later, he presented with acute urinary retention requiring suprapubic drainage. Urethroscopy showed a hem-o-lok clip strongly attached to the area between the vesico-urethral anastomosis and the urethral sphincter and a severe bladder neck contracture behind it. Following cold-knife urethral incision and clip removal, the bladder neck contracture was widely resected. At 3-month follow-up, the patient voided spontaneously with a peak flow rate of 9.5 ml/sec and absence of post-void residual urine, but leaked 240 ml urine at the 24-hour pad test. To date, at 1-year follow-up, his voiding situation remains unchanged. The present report provides further evidence for the risk of hem-o-lok clip migration causing bladder neck contracture, and is the first to demonstrate the potential of such complication to result into stress urinary incontinence.

The life expectancy of patients with localized prostate cancer at treatment initiation has increased, and post-treatment quality of life has become a key issue. The aim of this study is to assess the impact of Radical prostatectomy (RP) on patients' sexual health and satisfaction according to sexual motivation using a self-administered questionnaire completed by two groups of RP patients, with high or lower levels of sexual motivation. A total of 63 consecutive patients were included (mean age, 63.9 years), of whom 74.6% were being treated for erectile dysfunction (ED). After RP, patients reported lower sexual desire (52.4%), reduced intercourse frequency (79.4%), anorgasmia (39.7%), less satisfying orgasm (38.1%), climacturia (25.4%), greater distress (68.3%) and/or lower partner satisfaction (56.5%). Among the most sexually motivated patients, 76.0% reported loss of masculine identity, 52% loss of self-esteem and 36.0% anxiety about performance. These rates were lower among less motivated patients (52.6, 28.9, and 18.4%, respectively). Mean overall satisfaction score was 4.8 ± 2.9. The score was significantly lowered in motivated than less motivated patients (3.4 vs 5.8) (P = 0.001). In conclusion, RP adversely affected erectile and orgasmic functions but also sexual desire, self-esteem and masculinity. The more motivated patients experienced greater distress and were less satisfied.

Urinary continence is a driver of quality of life after radical prostatectomy. In this study we evaluated the impact of a biological bladder neck sling on the return of urinary continence after robot-assisted radical prostatectomy. This study compared early continence in patients undergoing robot-assisted radical prostatectomy with a sling and without a sling in a 2-group, 1:1, parallel, randomized controlled trial. Patients were blinded to group assignment. The primary outcome was defined as urinary continence (0 to 1 pad per day) at 1 month postoperatively. Inclusion criteria were organ confined prostate cancer and a prostate specific antigen less than 15 ng/ml. Exclusion criteria were any prior surgery on the prostate, a history of neurogenic bladder and history of pelvic radiation. A chi-squared test was used for the primary outcome. A total of 147 patients were randomized (control 74, sling 73) and 92% were available for primary end point analysis at 1 month. There were no significant differences in baseline or perioperative data except that operating room time was 20.1 minutes longer for the sling group (p=0.04). The continence rate was similar between the control and sling groups at 1 month (47.1% vs 55.2%, p=0.34) and 12 months (86.7% vs 94.5%, p=0.15), respectively. Adverse events were similar between the control and sling groups (10.8% vs 13.7%, p=0.59). The application of an absorbable urethral sling at robot-assisted radical prostatectomy was well tolerated with no increase in obstructive symptoms in this randomized trial. However, the sling failed to show a significant improvement in continence. Copyright © 2016 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Abstract Introduction: The primary aims of this study were to assess the learning curve effect of robot-assisted radical prostatectomy (RARP) in a large administrative database consisting of multiple U.S. hospitals and surgeons, and to compare the results of RARP with open radical prostatectomy (ORP) from the same settings. Materials and Methods: The patient population of study was from the Premier Perspective Database (Premier, Inc., Charlotte, NC) and consisted of 71,312 radical prostatectomies performed at more than 300 U.S. hospitals by up to 3739 surgeons by open or robotic techniques from 2004 to 2010. The key endpoints were surgery time, inpatient length of stay, and overall complications. We compared open versus robotic, results by year of procedures, results by case volume of specific surgeons, and results of open surgery in hospitals with and without a robotic system. Results: The mean surgery time was longer for RARP (4.4 hours, standard deviation [SD] 1.7) compared with ORP (3.4 hours, SD 1.5) in the same hospitals (p<0.0001). Inpatient stay was shorter for RARP (2.2 days, SD 1.9) compared with ORP (3.2 days, SD 2.7) in the same hospitals (p<0.0001). The overall complications were less for RARP (10.6%) compared with ORP (15.8%) in the same hospitals, as were transfusion rates. ORP results in hospitals without a robot were not better than ORP with a robot, and pretreatment co-morbidity profiles were similar in all cohorts. Trending of results by year of procedure showed no differences in the three cohorts, but trending of RARP results by surgeon experience showed improvements in surgery time, hospital stay, conversion rates, and complication rates. Conclusions: During the initial 7 years of RARP development, outcomes showed decreased hospital stay, complications, and transfusion rates. Learning curve trends for RARP were evident for these endpoints when grouped by surgeon experience, but not by year of surgery. PMID:24350787

We present a case of post-traumatic posterior urethral stricture and localized prostate cancer, which could be treated successfully with simultaneous radical perineal prostatectomy and membranous urethral stricture excision. After 6 months follow-up, the patient is continent with no evidence of stricture recurrence. Post-traumatic posterior urethral strictures can be managed surgically through a perineal approach with high success rates. Prostate surgery after pelvic fracture with posterior urethral distraction defects does not necessarily lead to stress urinary incontinence.

To report our intermediate experience in treating patients with severe incontinence using an adjustable perineal male sling with a tissue expander. An adjustable male sling procedure was performed on 21 patients with severe incontinence. The underlying etiology of urinary incontinence was radical prostatectomy in 13 patients, open prostatectomy in 5 patients and transurethral prostate resection in 3 patients. The difference between the classical and the adjustable sling is that in the latter there is a 25 mL tissue expander between the two layers of polypropylene mesh with an injection port. Adjustment of the sling was performed with saline via an inflation port, in case of recurrence or persistence of incontinence. The mean age of the patients was 66.2 ± 7.3 (50-79) years and mean pad usage was 6.4 ± 0.6 per day. The mean follow-up time was 40.1 ± 23.2 (6-74) months. The balloon was postoperatively inflated on average with 11.6 ± 5.7 (5-25) mL. After the mean 40.1 months of follow-up, 16 of the 21 patients (76.2%) were dry (11 patients, 0 pads; 5 patients using safety pads), 3 patients (14%) had mild and 2 (9.8%) had moderate degree post-prostatectomy urinary incontinence (PPI). The average maximum urine flow rate of the patients was 15.6 ± 4.7 (10-31) mL/s. No residual urine was found. In 2 patients, all parts of the device were removed due to infection and discomfort, and in 3 patients only the inflation component was removed due to local scrotal infection. Our results show that using an adjustable perineal male sling with a tissue expander seems to be an efficient, and safe surgical treatment option in patients with PPI.

A 53-year-old man presented to our hospital with a few-month history of fatigue and anorexia. His aging male's symptoms (AMS) score was 57, and the free testosterone value was low (6.5 pg/ml). He was diagnosed with severe late-onset hypogonadism indicative of androgen replacement therapy (ART). His serum prostate specific antigen was 8.7 ng/ml, and pelvic magnetic resonance imaging showed a low intensity area in the peripheral zone of the prostate. A systematic 10-core prostate biopsy revealed one core of adenocarcinoma with a Gleason score of 3 + 3=6. Imaging examination revealed organ-confined prostate cancer that was cT2aN0M0. Given his desire for ART for the treatment of hypogonadism, the patient underwent open radical prostatectomy. Pathologic examination demonstrated prostate adenocarcinoma that was pT2aN0, and Gleason score of 3 + 3=6. After confirming that the prostate specific antigen value was under 0.01 ng/ml for three years after prostatectomy, the patient received 125 mg methyltestosterone monthly. His hypogonadism-related symptoms diminished and AMS score dropped to 48. During a three-year follow-up of ART, no biochemical recurrence was found.

This exploratory study examines the experience of three gay couples managing sexual dysfunction as a result of undergoing a radical prostatectomy. Semi-structured interviews were conducted as part of a larger study at an urban hospital in Toronto, Ontario, Canada. Interview transcripts were transcribed verbatim, and analyzed using interpretative phenomenological analysis. The authors clustered 18 subordinate themes under 3 superordinate themes: (a) acknowledging change in sexual experience (libido, erectile function, sexual activity, orgasmic function); (b) accommodating change in sexual experience (strategies: emphasizing intimacy, embracing plan B, focus on the other; barriers: side-effect concerns, loss of naturalness, communication breakdown, failure to initiate, trial and failure, partner confounds); and (c) accepting change in sexual experience (indicators: emphasizing health, age attributions, finding a new normal; barriers: uncertain outcomes, treatment regrets). Although gay couples and heterosexual couples share many similar challenges, we discovered that gay men have particular sexual roles and can engage in novel accommodation practices, such as open relationships, that have not been noted in heterosexual couples. All couples, regardless of their level of sexual functioning, highlighted the need for more extensive programming related to sexual rehabilitation. Equitable rehabilitative support is critical to assist homosexual couples manage distress associated with prostatectomy-related sexual dysfunction.

To determine whether the prescribing patterns for nonindicated androgen suppression therapy (AST), using neoadjuvant AST as the model, changed according to the prevailing clinical evidence, changes in reimbursement, or evidence of increased harm from treatment. We identified 34,976 men with prostate cancer who had undergone radical prostatectomy within 12 months of diagnosis from the Surveillance, Epidemiology, and End Results-Medicare data set (1992-2007), and their clinical and demographic parameters were assessed. We measured the Medicare claims for receipt of AST before radical prostatectomy and calculated the annual rates of neoadjuvant AST, which were adjusted for confounding variables using multivariate logistic regression analysis, and compared them with the prevailing published clinical data on the outcomes of neoadjuvant AST, changes in reimbursement, or published data on clinical harm from treatment. The use of neoadjuvant AST increased from 7.8% in 1992 to a peak of 17.6% in 1996 and then decreased steadily to 4.6% in 2007. This rate change was significant on multivariate regression analysis, with a single join point in 1996 (P <.001), and corresponded to published data showing improved surgical margin rates and pathologic downstaging in the early 1990s and data showing no improvement in disease recurrence or overall survival beginning in 1997. Changes in reimbursement and evidence of harm from AST were not associated with the decreased use of neoadjuvant AST. Using neoadjuvant AST as the model for the nonindicated use of AST, physicians reduced AST use in response to high-level evidence showing a lack of benefit, despite the high reimbursement. This suggests that physicians adapt to emerging evidence and use evidence-based practice. Copyright © 2013 Elsevier Inc. All rights reserved.

Identification of chromosomal aberrations that may be used for diagnostic or prognostic evaluation of prostatic adenocarcinoma has been the subject of great interest. In a previous study, we applied the fluorescence in situ hybridization (FISH) method on paraffin-embedded material to show that trisomy 7 was associated with the progression of human prostate cancer. In this study, we attempted to assess the utility of the FISH technique in detecting aneuploidy in fine needle aspirate (FNA) smears of prostatic tissues and to compare FISH results with that of DNA flow cytometry (FCM). Paired samples of normal and tumor FNA smears were obtainedmore » from 10 radical prostatectomy specimens. Dual-color chromosomes 7 and 9-specific centromeric DNA probes were used for FISH. FISH analysis demonstrated increased frequencies of trisomy 7 cells in all 10 tumors studied when compared with the paired normals. In contrast, 6 of 10 tumors were determined to be diploid by FCM. Our results show that FNA of radical prostatectomy specimens is a practical method for obtaining suitable material for both FISH and FCM analyses of prostate carcinoma. Thus, interphase FISH may be a practical screening tool to determine aneuploidy in FNA smears of prostatic carcinoma.« less

To evaluate the impact of radical prostatectomy on lower urinary tract symptoms by using the International Prostate Symptom Score and International Prostate Symptom Score quality of life. The present prospective study comprised 804 patients having localized prostate cancer who underwent radical prostatectomy. International Prostate Symptom Score and International Prostate Symptom Score quality of life were recorded preoperatively, and at 1, 3, 6, 12 and 24 months. Two study groups were considered: group 1 included patients with International Prostate Symptom Score ≤7 (mild) and group 2 included patients with International Prostate Symptom Score ≥8 (moderate to severe). Student's t-test and logistic regression were carried out to detect a predictive factor of International Prostate Symptom Score ≤7 at 24 months. The mean International Prostate Symptom Score was 5.58 ± 6.6, 11.12 ± 7.1 and 7.62 ± 6 at baseline, 1 month and 3 months, respectively (P <0.0001). The mean quality of life score showed the same evolution with a significant difference at 1 and 3 months. The mean International Prostate Symptom Score was initially 1.57 ± 1.9 in group 1 and 13.51 ± 5.5 in group 2 (P <0.0001), evolving to 3.41 ± 3.1 and 7.69 ± 5.8 at 24 months (P <0.0001), respectively. The mean quality of life score was significantly different between the groups initially, and at 6 and 12 months with P <0.0001, P = 0.005 and P = 0.02, respectively. The multivariate logistic regression showed that age, prostate volume and preoperative International Prostate Symptom Score were independent predictive factors of International Prostate Symptom Score ≤7 at 24 months (P <0.0001). In group 2, 47 patients (17%) had an International Prostate Symptom Score ≥8 at 24 months, 15 of them (32%) having a QoL score ≥3. The present study shows the beneficial impact of radical prostatectomy on lower urinary tract symptoms. However, a proportion of patients with a

The aim of this retrospective study was to determine the respective accuracies of three types of functional MRI sequences-diffusion-weighted imaging (DWI), dynamic contrast-enhanced (DCE) MRI, and 3D (1)H-MR spectroscopy (MRS)-in the depiction of local prostate cancer recurrence after two different initial therapy options. From a cohort of 83 patients with suspicion of local recurrence based on prostate-specific antigen (PSA) kinetics who were imaged on a 3-T MRI unit using an identical protocol including the three functional sequences with an endorectal coil, we selected 60 patients (group A, 28 patients who underwent radical prostatectomy; group B, 32 patients who underwent external-beam radiation) who had local recurrence ascertained on the basis of a transrectal ultrasound-guided biopsy results and a reduction in PSA level after salvage therapy. All patients presented with a local relapse. Sensitivity with T2-weighted MRI and 3D (1)H-MRS sequences was 57% and 53%, respectively, for group A and 71% and 78%, respectively, for group B. DCE-MRI alone showed a sensitivity of 100% and 96%, respectively, for groups A and B. DWI alone had a higher sensitivity for group B (96%) than for group A (71%). The combination of T2-weighted imaging plus DWI plus DCE-MRI provided a sensitivity as high as 100% in group B. The performance of functional imaging sequences for detecting recurrence is different after radical prostatectomy and external-beam radiotherapy. DCE-MRI is a valid and efficient tool to detect prostate cancer recurrence in radical prostatectomy as well as in external-beam radiotherapy. The combination of DCE-MRI and DWI is highly efficient after radiation therapy. Three-dimensional (1)H-MRS needs to be improved. Even though it is not accurate enough, T2-weighted imaging remains essential for the morphologic analysis of the area.

PURPOSE Integrating ultra-sensitive PSA (uPSA) into surveillance of high-risk patients following radical prostatectomy (RP) potentially optimizes management by correctly identifying actual recurrences, promoting an early salvage strategy and minimizing overtreatment. The power of uPSA following surgery to identify eventual biochemical failures is tested. PATIENTS AND METHODS From 1991–2013, 247 high-risk patients with a median follow-up was 44 months after RP were identified (extraprostatic extension and/or positive margin). Surgical technique, initial PSA (iPSA), pathology and post-op PSA were analyzed. The uPSA assay threshold was 0.01 ng/mL. Conventional biochemical relapse (cBCR) was defined as PSA ≥0.2 ng/mL. Kaplan Meier and Cox multivariate analyses (MVA) compared uPSA recurrence vs. cBCR rates. RESULTS Sensitivity analysis identified uPSA ≥0.03 as the optimal threshold identifying recurrence. First post-op uPSA ≥0.03, Gleason grade, T-stage, iPSA, and margin status predicted cBCR. On MVA, only first post-op uPSA ≥0.03, Gleason grade, and T-stage independently predicted cBCR. First post-op uPSA ≥0.03 conferred the highest risk (HR 8.5, p<0.0001) and discerned cBCR with greater sensitivity than undetectable first conventional PSA (70% vs. 46%). Any post-op PSA ≥0.03 captured all failures missed by first post-op value (100% sensitivity) with accuracy (96% specificity). Defining failure at uPSA ≥0.03 yielded a median lead-time advantage of 18 months (mean 24 months) over the conventional PSA ≥0.2 definition. CONCLUSION uPSA ≥0.03 is an independent factor, identifies BCR more accurately than any traditional risk factors, and confers a significant lead-time advantage. uPSA enables critical decisions regarding timing and indication for post-op RT among high-risk patients following RP.

Purpose: To compare treatment impact on health-related quality of life (HRQL) in patients with localized prostate cancer, from before treatment to 2 years after the intervention. Methods and Materials: This was a longitudinal, prospective study of 614 patients with localized prostate cancer treated with radical prostatectomy (134), three-dimensional external conformal radiotherapy (205), and brachytherapy (275). The HRQL questionnaires administered before and after treatment (months 1, 3, 6, 12, and 24) were the Medical Outcomes Study 36-Item Short Form, the Functional Assessment of Cancer Therapy (General and Prostate Specific), the Expanded Prostate Cancer Index Composite (EPIC), and the American Urological Associationmore » Symptom Index. Differences between groups were tested by analysis of variance and within-group changes by univariate repeated-measures analysis of variance. Generalized estimating equations (GEE) models were constructed to assess between-group differences in HRQL at 2 years of follow-up after adjusting for clinical variables. Results: In each treatment group, HRQL initially deteriorated after treatment with subsequent partial recovery. However, some dimension scores were still significantly lower after 2 years of treatment. The GEE models showed that, compared with the brachytherapy group, radical prostatectomy patients had worse EPIC sexual summary and urinary incontinence scores (-20.4 and -14.1; p < 0.001), and external radiotherapy patients had worse EPIC bowel, sexual, and hormonal summary scores (-3.55, -5.24, and -1.94; p < 0.05). Prostatectomy patients had significantly better EPIC urinary irritation scores than brachytherapy patients (+4.16; p < 0.001). Conclusions: Relevant differences between treatment groups persisted after 2 years of follow-up. Radical prostatectomy had a considerable negative effect on sexual functioning and urinary continence. Three-dimensional conformal radiotherapy had a moderate negative impact on bowel

Radioactive iodine-125 implantation for cancer of the prostate.

Localized cancer of the prostate can be treated by radical prostatectomy, external beam irradiation, or radioactive implantation with similar survival results. Radical prostatectomy, however, almost universally results in impotency, although a new, nerve-sparing procedure may preserve potency in B1 patients. External beam irradiation radiates a large volume of tissue with significant rectal and bladder morbidity, 23-47% risk of impotency, and requires prolonged treatment (6-8 weeks). Radioactive implantation may be done suprapubically or transperineally using iodine-125, gold-198, or radon-222 permanent implantation techniques and iridium-192 or radium-226 removable implantation techniques. Interstitial iodine-125 implantation is frequently employed since it is a short procedure and limits the morbidity to a 7% incidence of impotency, 20% urinary complications, and 5% rectal complications. The overall 5-year survival of patients with iodine-125 is 79%, the survival rate decreasing with increasing T or N stage or increasing grade of tumor.

Prostate cancer, one of the most common malignant tumors among men, is closely associated with obesity and, thus far, several studies have suggested the association between obesity and aggressive pathological characteristics in the United States. However, the effect of obesity on prostate cancer mortality is controversial, and it remains unclear whether obesity contributes to the aggressiveness of prostate cancer in Asian patients. The aim of the present study was to investigate the association between body mass index (BMI) and the clinicopathological characteristics of prostate cancer in 2,003 Japanese patients who underwent radical prostatectomy. There was a significant association between higher BMI and higher Gleason score (GS). The multivariate analysis also revealed that BMI was an independent indicator for GS ≥8 at surgery. Moreover, among patients with lower prostate-specific antigen levels, biochemical recurrence-free survival was significantly worse in those with higher BMI. These results suggest that BMI may be a classifier for predicting adverse pathological findings and biochemical recurrence after radical prostatectomy in Japanese patients. PMID:28515927

To determine whether a variable definition of biochemical recurrence (BCR) based on clincopathologic features facilitates early identification of patients likely to suffer from disease progression. The definition of BCR after radical prostatectomy (RP) bears important implications for patient counseling and management; however, there remains a significant debate regarding the appropriate definition. The study cohort consisted of 3619 men who underwent RP for localized prostate cancer from 1989 to 2007, with data abstracted from the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) registry. Patients were stratified into three risk groups according to Cancer of the Prostate Risk Assessment post-Surgical (CAPRA-S) score. Three single threshold PSA cut-points for BCR were evaluated (PSA > or =0.05, > or =0.2 and > or =0.4 ng ml(-1)) as well as a variable cut-point defined by risk group. After reaching the cut-points, patients were followed for further PSA progression. The proportion of patients with BCR differed by cut-point and risk group, ranging from 7 to 37% (low risk), 22 to 58% (intermediate risk) and 60 to 86% (high risk). The positive-predictive value (PPV) for predicting further PSA progression was 49% for the PSA > or =0.05 ng ml(-1), 62% for the PSA > or =0.2 ng ml(-1), 65% for the PSA > or =0.4 ng ml(-1) and 68% for the risk-adjusted definition. Five-year progression-free survival was 39% for the risk-adjusted definition compared with 45-52% for the other definitions of BCR. These data suggest that a variable definition of BCR determined by clinicopathologic risk may improve the identification of early recurrence after RP without increasing the overdiagnosis of BCR. By using a risk-adjusted BCR definition, clinicians can better predict future PSA progression and more appropriately counsel patients regarding salvage therapies.

To define the nature of information posted on websites related to radical prostatectomy (RP), specifically its accuracy and comprehensiveness, as RP is associated with erectile dysfunction (ED). We reviewed 70 robotic RP (RARP) and 20 open RP (ORP) medical centres. Their websites were reviewed for various factors, by two separate reviewers whose reviews were not seen by each other. Websites were graded based on accuracy and comprehensiveness of information by the senior investigator. Of the academic and community-based RARP centres, 55% and 79% had specific websites (P < 0.05); 45% of RARP sites had generic information copied directly from the website of Intuitive Surgical (Sunnyvale, CA, USA; the manufacturer of the robotic system). ED was mentioned by only 54% of RARP sites and 45% of ORP sites; 17% of RARP sites were deemed accurate, compared with 30% of ORP sites (P < 0.05). Just over 1% of RARP sites were considered comprehensive, vs 10% of ORP sites (P < 0.05). A third of RARP sites had a direct link to the Intuitive Surgical website (16% academic vs 53% community, P < 0.05), compared to 10% of open sites (P < 0.05). Of most interest was that half of the RARP sites suggested that ED rates were lower for RARP than for ORP; this compared to ED rates being cited as lower for ORP on 5% of the ORP sites (P < 0.05). Despite the stature of RP as a treatment option for men with prostate cancer, and the recent increase in the use of RARP, the accuracy of information pertaining to sexual health on RP websites is poor, with many making false statements about the long-term outcomes for erectile function. This inadequacy appears to be greater on RARP than on ORP websites.

The risk of biochemical recurrence (BCR) following radical prostatectomy for pathologic Gleason 7 prostate cancer varies according to the proportion of Gleason 4 component. We sought to explore the value of several novel quantitative metrics of Gleason 4 disease for the prediction of BCR in men with Gleason 7 disease. We analyzed a cohort of 2630 radical prostatectomy cases from 1990-2007. All pathologic Gleason 7 cases were identified and assessed for quantity of Gleason pattern 4. Three methods were used to quantify the extent of Gleason 4: a quantitative Gleason score (qGS) based on the proportion of tumor composed of Gleason pattern 4, a size-weighted score (swGS) incorporating the overall quantity of Gleason 4, and a size index (siGS) incorporating the quantity of Gleason 4 based on the index lesion. Associations between the above metrics and BCR were evaluated using Cox proportional hazards regression analysis. qGS, swGS, and siGS were significantly associated with BCR on multivariate analysis when adjusted for traditional Gleason score, age, prostate specific antigen, surgical margin, and stage. Using Harrell's c-index to compare the scoring systems, qGS (0.83), swGS (0.84), and siGS (0.84) all performed better than the traditional Gleason score (0.82). Quantitative measures of Gleason pattern 4 predict BCR better than the traditional Gleason score. In men with Gleason 7 prostate cancer, quantitative analysis of the proportion of Gleason pattern 4 (quantitative Gleason score), as well as size-weighted measurement of Gleason 4 (size-weighted Gleason score), and a size-weighted measurement of Gleason 4 based on the largest tumor nodule significantly improve the predicted risk of biochemical recurrence compared with the traditional Gleason score.

Existing population-based reports on complication rates after minimally invasive radical prostatectomy (MIRP) did not address temporal trends. To examine contemporary temporal trends in perioperative MIRP outcomes. Between 2001 and 2007, 4387 patients undergoing MIRP were identified using the Nationwide Inpatient Sample. To examine the rates and trends of intraoperative and postoperative complications, transfusion rates, length of stay in excess of the median, and in-hospital mortality. We tested the effect of the late (2006-2007) versus the early (2001-2005) study period on all outcomes using multivariable logistic regression models controlled for clustering among hospitals. Intraoperative and postoperative complications decreased from 7.0% to 0.8% (p < 0.001) and from 28.5% to 8.7% (p < 0.001), respectively. Transfusion rates decreased from 3.5% to 2.1% (p = 0.3). Hospital length of stay >2 d decreased from 56% to 15% (p < 0.001). In multivariable analyses, intraoperative (odds ratio [OR]: 0.41; p = 0.002) and postoperative (OR: 0.65; p = 0.007) complications were less frequent in the late versus the early study period. Late study period patients were less likely to stay >2 d than early study period patients (OR: 0.34; p > 0.001). Limitations of these findings include the lack of adjustment for several patient variables including disease characteristics, surgeon variables including surgeon caseload, and the restriction to in-hospital events. Our analyses demonstrate that in-hospital complication rates and length of stay after MIRP decreased over time. This implies that temporal differences specific to complication rates after MIRP must be considered when comparisons are made with other radical prostatectomy techniques.

The aim of this meta-analysis was to evaluate the evidence of the effect of pelvic floor muscle training on urinary incontinence after radical prostatectomy. A bibliographic search was conducted in four databases. Studies were grouped according to the intervention program(muscle training versus control and individual home-based versus physiotherapist-guided muscle training). Eight studies were selected for meta-analysis after satisfying the selection criteria. The data show that pelvic floor muscle training improves continence rate in the short (RR=2.16; p<0.001), medium (RR=1.45; p=0.001) and long term (RR=1.23; p=0.019) after surgery. The number of randomized controlled trials and the heterogeneity in the study population and type of pelvic floor muscle training were the main limitations. Programs including at least three sets of 10 repetitions of muscle training daily appear to improve continence rate after radical prostatectomy. Our meta-analysis shows that muscle training programs for urinary incontinence provide similar results to those of physiotherapist-guided programs, therefore being more cost-effective. © 2014 S.

The recovery of potency following radical prostatectomy is complex and has a very wide range. In this study, we analyzed in detail the precise pattern of recovery of potency following robot-assisted radical prostatectomy (RARP). Prospectively collected database of patients with a minimum follow-up of 1 year after RARP were evaluated retrospectively. Of 503 patients identified, 483 patients completed the sexual health inventory for men (SHIM) preoperatively and postoperatively every 3 months for the first 12 months. Overall potency, usage of phosphodiesterase type-5 (PDE-5) inhibitors, and return to baseline erectile function were evaluated. Potency was defined as having erection that is sufficient for sexual intercourse more than 50% of attempts, while quality potency was defined as being potent without the use of PDE-5 inhibitors. Preoperatively, the overall potency and quality potency rate were 67.1% and 48.1%, respectively. Postoperatively, the overall potency rate was 61.4%, while the quality potency rate was 37.2%. In multivariate regression analysis, independent predictors of potency recovery were young age (<60), preoperative potency status, and bilateral preservation of neurovascular bundles (NVBs). In men with SHIM>21, the overall potency and quality potency rate were 79.7% and 41.2%, respectively. More importantly, only 21.4% of the men with normal erection preoperatively (SHIM>21) returned to baseline erectile function (SHIM>21) 12 months after surgery. This study indicates that young age (<60), preoperative potency, and bilateral preservation of NVBs were positive predictors of potency recovery following RARP. However, an overwhelming majority of men experience a deterioration in the overall quality of erection after RARP.

Prostatectomy: information provision and education for patients.

PubMed

Simpson, Paula

Following the diagnosis of prostate cancer, information should be imparted to ensure an informed decision regarding treatment can be made. The impact of a cancer diagnosis could lead men to opt for surgical intervention without fully understanding the consequences of treatment. Effective communication of evidence-based information can assist men to fully understand the consequences of treatment. Radical prostatectomy, whether robotically assisted laparoscopic or retropubic, will lead to quality-of-life issues with functional outcomes such as erectile dysfunction and urinary incontinence being at the forefront. Issues should be discussed and communicated in depth so that frustration and regret following treatment are avoided. A cautious approach to information provision should be considered so the patient does not feel in a position of information overload. Advanced communication skills are of utmost importance to ensure information is tailored to suit individual needs, as no one model of information giving suits all. This article is a rapid literature search relating to post-prostatectomy functional outcomes and how communication and information giving before treatment assists with acceptance of treatment outcomes.

Radical prostatectomy in the 21st century - the gold standard for localized and locally advanced prostate cancer.

PubMed

Schostak, M; Miller, K; Schrader, M

2008-01-01

Radical prostatectomy for treatment of prostate cancer is a technically sophisticated operation. Simpler therapies have therefore been developed in the course of decades. The decisive advantage of a radical operation is the chance of a cure with minimal collateral damage. It is the only approach that enables precise tumor staging. The 10-year progression-free survival probability is approximately 85% for a localized tumor with negative resection margins. This high cure rate is unsurpassed by competitive treatment modalities. Nowadays, experienced surgeons achieve excellent functional results (for example, recovery of continence and erectile function) with minimum morbidity. Even in the locally advanced stage, results are very good compared to those obtained with other treatment modalities. Pathological staging enables stratified adjuvant therapy based on concrete information. The overall prognosis can thus be significantly improved.

Natural language processing (NLP) software programs have been widely developed to transform complex free text into simplified organized data. Potential applications in the field of medicine include automated report summaries, physician alerts, patient repositories, electronic medical record (EMR) billing, and quality metric reports. Despite these prospects and the recent widespread adoption of EMR, NLP has been relatively underutilized. The objective of this study was to evaluate the performance of an internally developed NLP program in extracting select pathologic findings from radical prostatectomy specimen reports in the EMR. An NLP program was generated by a software engineer to extract key variables from prostatectomy reports in the EMR within our healthcare system, which included the TNM stage, Gleason grade, presence of a tertiary Gleason pattern, histologic subtype, size of dominant tumor nodule, seminal vesicle invasion (SVI), perineural invasion (PNI), angiolymphatic invasion (ALI), extracapsular extension (ECE), and surgical margin status (SMS). The program was validated by comparing NLP results to a gold standard compiled by two blinded manual reviewers for 100 random pathology reports. NLP demonstrated 100% accuracy for identifying the Gleason grade, presence of a tertiary Gleason pattern, SVI, ALI, and ECE. It also demonstrated near-perfect accuracy for extracting histologic subtype (99.0%), PNI (98.9%), TNM stage (98.0%), SMS (97.0%), and dominant tumor size (95.7%). The overall accuracy of NLP was 98.7%. NLP generated a result in <1 second, whereas the manual reviewers averaged 3.2 minutes per report. This novel program demonstrated high accuracy and efficiency identifying key pathologic details from the prostatectomy report within an EMR system. NLP has the potential to assist urologists by summarizing and highlighting relevant information from verbose pathology reports. It may also facilitate future urologic research through the rapid and

We compared location of positive cores in biopsy and location of positive surgical margin (PSM) following radical prostatectomy. This retrospective analysis included patients who were diagnosed as prostate cancer by standard 12-core transrectal ultrasonography guided prostate biopsy, and who have PSM after radical prostatectomy. After exclusion of number of biopsy cores <12, and lack of biopsy location data, 46 patients with PSM were identified. Locations of PSM in pathologic specimen were reported as 6 difference sites (apex, base and lateral in both sides). Discordance of biopsy result and PSM was defined when no positive cores in biopsy was identified at the location of PSM. Most common location of PSM were right apex (n=21) and left apex (n=15). Multiple PSM was reported in 21 specimens (45.7%). In 32 specimens (69.6%) with PSM, one or more concordant positive biopsy cores were identified, but 14 specimens (28%) had no concordant biopsy cores at PSM location. When discordant rate was separated by locations of PSM, right apex PSM had highest rate of discordant (38%). The discordant group had significantly lower prostate volume and lower number of positive cores in biopsy than concordant group. This study showed that one fourth of PSM occurred at location where tumor was not detected at biopsy and that apex PSM had highest rate of discordant. Careful dissection to avoid PSM should be performed in every location, including where tumor was not identified in biopsy.

To compare the initial costs of the three most established treatments for clinically localized prostate cancer according to risk, age and comorbidity groups, from the healthcare provider's perspective. We carried out a cost comparison study in a sample of patients consecutively recruited between 2003 and 2005 from a functional unit for prostate cancer treatment in Catalonia (Spain). The use of services up to 6 months after the treatment start date was obtained from hospital databases and direct costs were estimated by micro-cost calculation. Information on the clinical characteristics of patients and treatments was collected prospectively. Costs were compared by using nonparametric tests comparing medians (Kruskall-Wallis) and a semi-logarithmic multiple regression model. Among the 398 patients included, the cost difference among treatments was statistically significant: medians were € 3,229.10, € 5,369.00 and € 6,265.60, respectively, for the groups of patients treated with external 3D conformal radiotherapy, brachytherapy and radical retropublic prostatectomy, (p<0.001). In the multivariate analysis (adjusted R(2)=0.8), the average costs of brachytherapy and external radiotherapy were significantly lower than that of prostatectomy (coefficient -0.212 and -0.729, respectively). Radical prostatectomy proved to be the most expensive treatment option. Overall, the estimated costs in our study were lower than those published elsewhere.

Achieving cancer-free surgical margins in oncologic surgery is critical to reduce the need for additional adjuvant treatments and minimize tumor recurrence; however, there is a delicate balance between completeness of tumor removal and preservation of adjacent tissues critical for normal post-operative function. We sought to establish the feasibility of video-rate structured illumination microscopy (VR-SIM) of the intact removed tumor surface as a practical and non-destructive alternative to intra-operative frozen section pathology, using prostate cancer as an initial target. We present the first images of the intact human prostate surface obtained with pathologically-relevant contrast and subcellular detail, obtained in 24 radical prostatectomy specimens immediately after excision. We demonstrate that it is feasible to routinely image the full prostate circumference, generating gigapixel panorama images of the surface that are readily interpreted by pathologists. VR-SIM confirmed detection of positive surgical margins in 3 out of 4 prostates with pathology-confirmed adenocarcinoma at the circumferential surgical margin, and furthermore detected extensive residual cancer at the circumferential margin in a case post-operatively classified by histopathology as having negative surgical margins. Our results suggest that the increased surface coverage of VR-SIM could also provide added value for detection and characterization of positive surgical margins over traditional histopathology.

Neuropathic pain is common and debilitating with limited effective treatments. Macrophage/microglial activation along ascending somatosensory pathways following peripheral nerve injury facilitates neuropathic pain. However, polarization of macrophages/microglia in neuropathic pain is not well understood. Photobiomodulation treatment has been used to decrease neuropathic pain, has anti-inflammatory effects in spinal injury and wound healing models, and modulates microglial polarization in vitro. Our aim was to characterize macrophage/microglia response after peripheral nerve injury and modulate the response with photobiomodulation. Adult male Sprague-Dawley rats were randomly assigned to sham (N = 13), spared nerve injury (N = 13), or injury + photobiomodulation treatment groups (N = 7). Mechanical hypersensitivity was assessed with electronic von Frey. Photobiomodulation (980 nm) was applied to affected hind paw (output power 1 W, 20 s, 41cm above skin, power density 43.25 mW/cm 2 , dose 20 J), dorsal root ganglia (output power 4.5W, 19s, in skin contact, power density 43.25 mW/cm 2 , dose 85.5 J), and spinal cord regions (output power 1.5 W, 19s, in skin contact, power density 43.25 mW/cm 2 , dose 28.5 J) every other day from day 7-30 post-operatively. Immunohistochemistry characterized macrophage/microglial activation. Injured groups demonstrated mechanical hypersensitivity 1-30 days post-operatively. Photobiomodulation-treated animals began to recover after two treatments; at day 26, mechanical sensitivity reached baseline. Peripheral nerve injury caused region-specific macrophages/microglia activation along spinothalamic and dorsal-column medial lemniscus pathways. A pro-inflammatory microglial marker was expressed in the spinal cord of injured rats compared to photobiomodulation-treated and sham group. Photobiomodulation-treated dorsal root ganglion macrophages expressed anti-inflammatory markers. Photobiomodulation effectively reduced

WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: It has been suggested that a very short positive margin does not confer additional risk of BCR after radical prostatectomy. This study shows that even very short PSM is associated with increased risk of BCR. To re-evaluate, in a larger cohort with longer follow-up, our previously reported finding that a positive surgical margin (PSM) ≤ 1 mm may not confer an additional risk for biochemical recurrence (BCR) compared with a negative surgical margin (NSM). Margin status and length were evaluated in 2866 men treated with radical prostatectomy (RP) for clinically localized prostate cancer at our institution from 1994 to 2009. We compared the BCR-free survival probability of men with NSMs, a PSM ≤ 1 mm, and a PSM < 1 mm using the Kaplan-Meier method and a Cox regression model adjusted for preoperative prostate-specific antigen (PSA) level, age, pathological stage and pathological Gleason score (GS). Compared with a NSM, a PSM ≤ 1 mm was associated with 17% lower 3-year BCR-free survival for men with pT3 and GS ≥ 7 tumours and a 6% lower 3-year BCR-free survival for men with pT2 and GS ≤ 6 tumours (log-rank P < 0.001 for all). In the multivariate model, a PSM ≤ 1 mm was associated with a probability of BCR twice as high as that for a NSM (hazard ratio [HR] 2.2), as were a higher PSA level (HR 1.04), higher pathological stage (HR 2.7) and higher pathological GS (HR 3.7 [all P < 0.001]). In men with non-organ-confined or high grade prostate cancer, a PSM ≤ 1 mm has a significant adverse impact on BCR rates. © 2012 The Authors. BJU International © 2012 BJU International.

Technical Note: Method to correlate whole-specimen histopathology of radical prostatectomy with diagnostic MR imaging

McGrath, Deirdre M., E-mail: d.mcgrath@sheffield.ac.uk; Lee, Jenny; Foltz, Warren D.

Purpose: Validation of MRI-guided tumor boundary delineation for targeted prostate cancer therapy is achieved via correlation with gold-standard histopathology of radical prostatectomy specimens. Challenges to accurate correlation include matching the pathology sectioning plane with the in vivo imaging slice plane and correction for the deformation that occurs between in vivo imaging and histology. A methodology is presented for matching of the histological sectioning angle and position to the in vivo imaging slices. Methods: Patients (n = 4) with biochemical failure following external beam radiotherapy underwent diagnostic MRI to confirm localized recurrence of prostate cancer, followed by salvage radical prostatectomy. High-resolutionmore » 3-D MRI of the ex vivo specimens was acquired to determine the pathology sectioning angle that best matched the in vivo imaging slice plane, using matching anatomical features and implanted fiducials. A novel sectioning device was developed to guide sectioning at the correct angle, and to assist the insertion of reference dye marks to aid in histopathology reconstruction. Results: The percentage difference in the positioning of the urethra in the ex vivo pathology sections compared to the positioning in in vivo images was reduced from 34% to 7% through slicing at the best match angle. Reference dye marks were generated, which were visible in ex vivo imaging, in the tissue sections before and after processing, and in histology sections. Conclusions: The method achieved an almost fivefold reduction in the slice-matching error and is readily implementable in combination with standard MRI technology. The technique will be employed to generate datasets for correlation of whole-specimen prostate histopathology with in vivo diagnostic MRI using 3-D deformable registration, allowing assessment of the sensitivity and specificity of MRI parameters for prostate cancer. Although developed specifically for prostate, the method is readily

Minimally invasive surgical techniques have many benefits, including reduced postoperative pain. Despite this, most patients require opioid analgesia, which can have significant side effects and toxicity. We report the first urologic study using multimodal analgesia with pregabalin, a gabapentinoid. The present retrospective study included 60 patients who underwent robotic-assisted laparoscopic radical prostatectomy. Of the 60 patients, 30 received multimodal treatment with pregabalin 150 mg, acetaminophen 975 mg, and celecoxib 400 mg orally 2 hours before the start of the procedure and continued postoperatively. These patients were compared with 30 consecutive previous patients, who had received a standard postoperative analgesic regimen with intravenous ketorolac 15 mg every 6 hours with oxycodone 5 mg and acetaminophen 325 mg, 1 to 2 tablets, every 4 hours as needed for pain. The patients in the multimodal treatment group had a significantly reduced intraoperative opioid requirement, as measured by the mean morphine equivalent dose administered (38.4 ± 2.73 mg vs 49.1 ± 2.65 mg; P < .01). The mean postoperative opioid use was also significantly reduced (10.7 ± 2.82 mg vs 26.2 ± 6.56 mg; P = .034), as was the mean total morphine equivalent dose administered (49.1 ± 2.7 mg vs 75.3 ± 4.6 mg; P < .001). The operative time, estimated operative blood loss, antiemetic use, postoperative creatinine and hemoglobin levels, and length of stay were similar in the 2 groups. No operative or treatment complications occurred in either group. The present retrospective review has indicated that a multimodal analgesic approach with pregabalin and celecoxib administered preoperatively decreases intraoperative and postoperative opioid use in patients undergoing robotic-assisted laparoscopic radical prostatectomy.

CONTEXT The safety and feasibility of robotic-assisted radical prostatectomy (RARP) compared with retropubic radical prostatectomy(RRP) is debated. Recently, a number of large-scale and high-quality studies have been conducted. OBJECTIVE To obtain a more valid assessment, we update the meta-analysis of RARP compared with RRP to assessed its safety and feasibility in treatment of prostate cancer. METHODS A systematic search of Medline, Embase, Pubmed, and the Cochrane Library was performed to identify studies that compared RARP with RRP. Outcomes of interest included perioperative, pathologic variables and complications. RESULTS 78 studies assessing RARP vs. RRP were included for meta-analysis. Although patients underwent RRP have shorter operative time than RARP (WMD: 39.85 minutes; P < 0.001), patients underwent RARP have less intraoperative blood loss (WMD = -507.67ml; P < 0.001), lower blood transfusion rates (OR = 0.13; P < 0.001), shorter time to remove catheter (WMD = -3.04day; P < 0.001), shorter hospital stay (WMD = -1.62day; P < 0.001), lower PSM rates (OR:0.88; P = 0.04), fewer positive lymph nodes (OR:0.45;P < 0.001), fewer overall complications (OR:0.43; P < 0.001), higher 3- and 12-mo potent recovery rate (OR:3.19;P = 0.02; OR:2.37; P = 0.005, respectively), and lower readmission rate (OR:0.70, P = 0.03). The biochemical recurrence free survival of RARP is better than RRP (OR:1.33, P = 0.04). All the other calculated results are similar between the two groups. CONCLUSIONS Our results indicate that RARP appears to be safe and effective to its counterpart RRP in selected patients. PMID:27852051

In our series of 1,900 endoscopic extraperitoneal radical prostatectomies (EERPE) the incidence of symptomatic lymphocele following simultaneous pelvic lymph node dissection (PLND) is between 3 and 14% depending on the extent of lymph node dissection. We report the impact of bilateral peritoneal fenestration after completion of extraperitoneal prostatectomy and PLND on the incidence of lymphocele, postoperative pain and complications. A total of 100 consecutive patients undergoing EERPE and extended PLND were allocated into two groups. In Group A (n = 50) a 4-6 cm incision was performed bilaterally over the external iliac vessels down to the obturator fossa after completion of the main procedure. In Group B (n = 50) no peritoneal incisions were made. The postoperative assessment protocol included a visual analogue pain scale administered three times daily for 6 days, analgesia requirement, and ultrasound examination on 4th and 8th days, and 3 months postoperatively. CRP and leucocyte counts were measured on 1st and 2nd postoperative days. Complications were recorded according to our standard protocol using the Clavien classification. Three patients (6%) in Group A were found to have lymphoceles, none of which were symptomatic. Significantly more patients in Group B developed a lymphocele, (n = 16, 32%, P < 0.001) of which a significant number were symptomatic (n = 7, 14%, P < 0.001) and required laparoscopic fenestration. No significant difference was observed between the pain score in either group. Mean pain scores were 3.4 versus 3.8 at 6 h, and 0.8 versus 1.1 at 6 days, respectively. No difference in analgesia requirement, serum inflammatory markers and return to normal bowel activity was observed between the groups. This study demonstrates that peritoneal fenestration significantly reduces the incidence of both symptomatic and asymptomatic lymphocele, without an increase in postoperative morbidity. As symptomatic lymphocele is one of the most common

Prostate cancer is one of the most common cancers in the elderly population. The standard treatment is radical prostatectomy (RARP). However, urologists do not have consents on the postoperative urine drainage management (suprapubic tube (ST)/ urethral catheter (UC)). Thus, we try to compare ST drainage to UC drainage after robot-assisted radical prostatectomy regarding to comfort, recovery rate and continence using the method of meta-analysis. A systematic search was performed in Dec. 2017 on PubMed, Medline, Embase and Cochrane Library databases. The authors independently reviewed the records to identify studies comparing ST with UC of patients underwent RARP. Meta-analysis was performed using the extracted data from the selected studies. Seven studies, including 3 RCTs, with a total of 946 patients met the inclusion criteria and were included in our meta-analysis. Though there was no significant difference between the ST group and the UC group on postoperative pain (RR1.73, P 0.20), our study showed a significant improvement on bother or discomfort, defined as trouble in hygiene and sleep, caused by catheter when compared two groups at postoperative day (POD) 7 in ST group (RR2.05, P 0.006). There was no significant difference between the ST group and UC group on urinary continence (RR0.98, P 0.74) and emergency department visit (RR0.61, P 0.11). The rates of bladder neck contracture and other complications were very low in both groups. Compared to UC, ST showed a weak advantage. So it might be a good choice to choose ST over RARP.

Retrospective single institution data suggest that postoperative pain after robot-assisted laparoscopic radical prostatectomy is decreased by early removal of the urethral catheter with suprapubic tube drainage. In a randomized patient population we determined whether suprapubic tube drainage with early urethral catheter removal would improve postoperative pain compared with urethral catheter drainage alone. Men with a body mass index of less than 40 kg/m(2) who had newly diagnosed prostate cancer and elected robot-assisted laparoscopic radical prostatectomy were included in analysis. Block randomization by surgeon was used and randomization assignment was done after completing the urethrovesical anastomosis. In patients assigned to suprapubic tube drainage the urethral catheter was removed on postoperative day 1 and all catheters were removed on postoperative day 7. Visual analog pain scale and satisfaction questionnaires were administered on postoperative days 0, 1 and 7. A total of 29 patients were randomized to the urethral catheter vs 29 to the suprapubic tube plus early urethral catheter removal at the time of interim futility analysis. Mean visual analog pain scale scores did not differ between the groups at any time point and a similar percent of patients cited the catheter as the greatest bother with nonsignificant differences in treatment related satisfaction. Complications during postoperative week 1 did not vary between the groups. Based on interim results the trial was terminated due to lack of effect. Patients randomized to suprapubic tube vs urethral catheter drainage for the week after prostatectomy had similar pain, catheter related bother and treatment related satisfaction in the perioperative period. We no longer routinely offer suprapubic tube drainage with early urethral catheter removal at our institution. Copyright © 2014 American Urological Association Education and Research, Inc.

The current study was undertaken within the framework of a screening trial to compare the health-related quality-of-life (HRQOL) outcomes of two primary treatment modalities for localized prostate cancer: radical prostatectomy and external-beam radiotherapy. We conducted a prospective longitudinal cohort study among 278 patients with early screen-detected (59%) or clinically diagnosed (41%) prostate cancer using both generic and disease-specific HRQOL measures (SF-36, UCLA Prostate Cancer Index [urinary and bowel modules] and items relating to sexual functioning) at three points in time: t1 (baseline), t2 (6 months later), and t3 (12 months after t1). Questionnaires were completed by 88% to 93% of all initially enrolled patients. Patients referred for primary radiotherapy were significantly older than prostatectomy patients (63 v 68 years, P <.01). Analyses (adjusted for age and pretreatment level of functioning) revealed poorer levels of generic HRQOL after radiotherapy. Prostatectomy patients reported significantly higher (P <.01) posttreatment incidences of urinary incontinence (39% to 49%) and erectile dysfunction (80% to 91%) than radiotherapy patients (respectively, 6% to 7% and 41% to 55%). Bowel problems (urgency) affected 30% to 35% of the radiotherapy group versus 6% to 7% of the prostatectomy group (P <.01). Patients with screen-detected and clinically diagnosed cancer reported similar posttreatment HRQOL. Prostatectomy and radiotherapy differed in the type of HRQOL impairment. Because the HRQOL effects may be valued differently at the individual level, patients should be made fully aware of the potential benefits and adverse consequences of therapies for early prostate cancer. Differences in posttreatment HRQOL were not related to the method of cancer detection.

Apical dissection in robot-assisted radical prostatectomy (RARP) affects not only cancer control, but also continence recovery. To describe a novel approach for apical dissection, the collar technique, to reduce apical positive surgical margins (PSMs). A total of 189 consecutive patients (81 in the control group, 108 in the collar technique group) underwent RARP at a single center. rates of apical PSMs; secondary outcome: urinary continence. The urethral sphincter complex is incised 2-3mm distally to the apex, to stay farther from it and reduce PSMs; the underlying smooth muscle is exposed and incised closer to the apex to preserve the maximal length of the lissosphincter. Mann-Whitney U and chi-square tests compared median and proportions between the two groups, respectively. Univariate logistic regression tested the association between technique employed and risk of apical PSMs. Fourteen patients (7.4%) revealed apical PSMs (9.9% in the control group, 5.6% in the collar group; p=0.7). When the collar technique was used, significantly lower rates of apical PSMs occurred in pT2 disease (0% vs 7.1%; p=0.03). In case of apical tumor at preoperative magnetic resonance imaging (MRI; n=43), the collar technique determined significantly lower overall (9.7% vs 42%) and apical (3.2% vs 42%) PSMs (all p≤0.02). Continence recovery in the collar and control groups was similar. When preoperative MRI showed an apical tumor, the collar technique had a significantly lower risk of apical PSMs (odds ratio: 0.05, p=0.009). The collar technique reduces the rates of apical PSMs in case of apical tumor, preserving the length of the lissosphincter. We describe a novel approach for apical dissection during robot-assisted radical prostatectomy. Our technique reduces the rates of apical surgical margins in case of apical tumor at preoperative magnetic resonance imaging and leads to optimal continence recovery.

Tertiary Gleason patterns and biochemical recurrence after prostatectomy: proposal for a modified Gleason scoring system.

2009-10-01

We investigated the relationship between the tertiary Gleason component in radical prostatectomy specimens and biochemical recurrence in what is to our knowledge the largest single institution cohort to date. We evaluated data on 3,230 men who underwent radical prostatectomy at our institution from 2000 to 2005. Tertiary Gleason component was defined as Gleason grade pattern 4 or greater for Gleason score 6 and Gleason grade pattern 5 for Gleason score 7 or 8. Biochemical recurrence curves for cancer with tertiary Gleason component were intermediate between those of cancer without a tertiary Gleason component in the same Gleason score category and cancer in the next higher Gleason score category. The only exception was that Gleason score 4 + 3 = 7 with a tertiary Gleason component behaved like Gleason score 8. The tertiary Gleason component independently predicted recurrence when factoring in radical prostatectomy Gleason score, radical prostatectomy stage and prostate specific antigen (HR 1.45, p = 0.029). Furthermore, the magnitude of the tertiary Gleason component effect on recurrence did not differ by Gleason score category (p = 0.593). Although the tertiary Gleason component is frequently included in pathology reports, it is routinely omitted in other situations, such as predictive nomograms, research studies and patient counseling. The current study adds to a growing body of evidence highlighting the importance of the tertiary Gleason component in radical prostatectomy specimens. Accordingly consideration should be given to a modified radical prostatectomy Gleason scoring system that incorporates tertiary Gleason component in intuitive fashion, including Gleason score 6, 6.5 (Gleason score 6 with tertiary Gleason component), 7 (Gleason score 3 + 4 = 7), 7.25 (Gleason score 3 + 4 = 7 with tertiary Gleason component), 7.5 (Gleason score 4 + 3), 8 (Gleason score 4 + 3 with tertiary Gleason component or Gleason score 8), 8.5 (Gleason score 8 with tertiary Gleason

During the last decade urologists have faced a dramatic increase in robotic surgery. Despite the exceptional acceptance of this technique there is a complete lack of evidence for the equi-efficacy or superiority of this technique compared to open or laparoscopic prostatectomy. There is now an increasing body of evidence for the evaluation of robotic assisted prostatectomy. Robotic assisted prostatectomy is a safe procedure. The rate of technical failure is small. The rate of surgical complications is comparable with that of open or conventional laparoscopic prostatectomy. Similar to the conventional laparoscopic prostatectomy there is a trend for a minor blood loss and a smaller transfusion rate compared to the retropubic approach. In recent meta-analyses there is no advatage regarding the oncological or functional outcome for robotic prostatectomy. Neither the rate of positive surgical margins nor the rate of biochemical recurrence favours robotic prostatectomy. Regarding functional outcome some publications describe better results for urinary and sexual function for robotic surgery. Careful evaluation of these data reveals a low level of evidence due to a strong bias in favour of robotic surgery. In contrast, recent analysis of "Medicare" data reveal a considerable poorer urinary function after robotic prostatectomy compared to open retropubic prostatectomy. The Urological Board of the Helios Hospital Group does not recommend the use of a robotic device for radical prostatectomy. © Georg Thieme Verlag KG Stuttgart · New York.

Robot-assisted radical prostatectomy: a case series of the first 100 patients -constitutional introduction and implementation on the basis of comprehensive department of minimal invasive surgery center-

Background Although a very small number of Japanese hospitals had been performing robotic surgery before 2011, the number now using it is increasing rapidly due to the application of health insurance to robotic surgery for prostate cancer (PCa) since April, 2012. We report our initial experience of treating 100 patients by robot-assisted radical prostatectomy (RARP) with a focus on constitutional introduction and implementation based on minimal invasive surgery center (MISC) and patient outcomes. Methods The MISC involved all of the hospital sections related to robotic surgery including four surgery departments, anesthesiology, operating room nurses, medical engineers. The data were prospectively collected from the first 100 consecutive patients who underwent RARP under supervision of MISC for localized PCa from October 2010 to December 2012. Results During the period of our initial 100 cases of RARP, the gynecology, respiratory and digestive surgery departments performed initial cases of 20, 33 and 23 robotic surgeries under control of MISC. Peri-operative complications in RARP appeared to be minimal with no cases of intra-operative open conversion. The positive surgical margin rate was 19% for the entire series. At the median follow-up time of 11.9 months, 91% of patients had undetectable PSA levels, and 76% of patients were not using pads. Sequential urinary functional data indicated a significant beneficial effect on lower urinary tract symptoms beyond cancer control over a period of several months. Although the pre-operative potent patient number was small, the transitions of constant potency recovery at precise time points were shown according to different nerve sparing procedures. Conclusions This is the first report of an initial 100 RARP cases that were implemented using the constitutional framework of an academic institution. The MISC is providing immeasurable benefits from the aspects of patient safety and education for the robotic surgical team. RARP

To determine the significant independent predictors of inguinal hernia development after radical prostatectomy (RP) so that prophylactic measures can be undertaken in those at increased risk. Although inguinal hernia is a recognized complication after RP, the risk factors have not been well elucidated. From January 1999 to June 2007, 4592 consecutive patients underwent open retropubic RP or laparoscopic RP without previous radiotherapy. The median follow-up was 36.9 months (interquartile range 20.3, 60.6). Comorbidities were recorded, as well as the occurrence of inguinal hernia, wound infection, and bladder neck contracture. Cox proportional hazards analysis was performed for the predictors of inguinal hernia after RP on multivariate analysis. Inguinal hernia developed after RP in 68 men (1.5%) men at a median follow-up of 7.9 months (interquartile range 4.3, 18.1). The laterality was bilateral in 7, right in 27, left in 24, and not documented in 10 patients. The significant independent predictors of inguinal hernia included age (hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.01-1.09, P = .016), body mass index (HR 0.91, 95% CI 0.85-0.98, P = .011), history of inguinal hernia repair (HR 3.9, 95% CI 1.8-8.2, P <.001), and bladder neck contracture (HR 2.8, 95% CI 1.3-5.9, P = .007) but not the RP approach (HR 1.08, 95% CI 0.60-1.96, P = .80 for laparoscopic RP vs retropubic RP). The results of our study have indicated that older patients, thinner patients, those with previous inguinal hernia repair, and those developing bladder neck contracture are at increased risk of developing an inguinal hernia. These factors might identify a subset for whom evaluation for subclinical hernia might allow prophylactic inguinal hernia repair at RP. Copyright © 2011 Elsevier Inc. All rights reserved.

To review and compare the outcome of patients undergoing radical retropubic prostatectomy (RRP) or radical perineal prostatectomy (RPP) for clinically localized prostate cancer. From 1988 to 1997, 1382 men who were treated by RRP and 316 by RPP were identified from databases of the Uniformed Services Urology Research Group. The following variables were assessed; age, race, prostate-specific antigen (PSA) level before surgery, clinical stage, biopsy Gleason sum, estimated blood loss (EBL), margin-positive rate, pathological stage, biochemical recurrence rate, short and long-term complication rates, impotence and incontinence rates. To eliminate selection bias, the analysis was concentrated on pairs of patients matched by race, preoperative PSA level, clinical stage and biopsy Gleason sum. In the 190 matched patients there were no significant differences between the RRP and RPP groups in either organ-confined (57% vs 55%), margin-positive (39% vs 43%), or biochemical recurrence rates (12.9% vs 17.6% at a mean follow-up of 47.1 vs 42.9 months), respectively. The mean EBL was 1575 mL in the RRP group and 802 mL in the RPP group (P < 0.001). The only significant difference in complication rates was a higher incidence of rectal injury in the RPP group (4.9%) than in the RRP group (none, P < 0.05). In similar populations of patients, RPP offers equivalent organ-confined, margin-positive and biochemical recurrence rates to RRP, while causing significantly less blood loss.

Of men with very low risk prostate cancer at biopsy recent evidence shows that black American men are at greater risk for adverse oncologic outcomes after radical prostatectomy. We studied radical prostatectomy specimens from black and white men at very low risk to determine whether there are systematic pathological differences. Radical prostatectomy specimens were evaluated in men with National Comprehensive Cancer Network® (NCCN) very low risk prostate cancer. At diagnosis all men underwent extended biopsy sampling (10 or more cores) and were treated in the modern Gleason grade era. We analyzed tumor volume, grade and location in 87 black and 89 white men. For each specimen the dominant nodule was defined as the largest tumor with the highest grade. Compared to white men, black men were more likely to have significant prostate cancer (61% vs 29%), Gleason 7 or greater (37% vs 11%, each p <0.001) and a volume of greater than 0.5 cm(3) (45% vs 21%, p = 0.001). Dominant nodules in black men were larger (median 0.28 vs 0.13 cm(3), p = 0.002) and more often anterior (51% vs 29%, p = 0.003). In men who underwent pathological upgrading the dominant nodule was also more frequently anterior in black than in white men (59% vs 0%, p = 0.001). Black men with very low risk prostate cancer at diagnosis have a significantly higher prevalence of anterior cancer foci that are of higher grade and larger volume. Enhanced imaging or anterior zone sampling may detect these significant anterior tumors, improving the outcome in black men considering active surveillance.

Objectives Erectile rehabilitation (ER) following radical prostatectomy (RP) is considered an essential component to help men regain erectile functioning; however many men have difficulty adhering to this type of a program. This qualitative study explored men's experience with ER, erectile dysfunction (ED), and ED treatments to inform a psychological intervention designed to help men adhere to ER post-RP. Methods Thirty men, one to three years post-RP, who took part in an ER program, participated in one of four focus groups. Thematic analysis was used to identify the primary themes. Results Average age was 59 (SD=7); mean time since surgery was 26 months (SD=6). Six primary themes emerged: 1) frustration with the lack of information about post-surgery ED; 2) negative emotional impact of ED and avoidance of sexual situations; 3) negative emotional experience with penile injections and barriers leading to avoidance; 4) the benefit of focusing on the long-term advantage of ER versus short-term anxiety; 5) using humor to help cope; and 6) the benefit of support from partners and peers. Conclusions Men's frustration surrounding ED can lead to avoidance of sexual situations and ED treatments, which negatively impact men's adherence to an ER program. The theoretical construct of Acceptance and Commitment Therapy (ACT) was used to place the themes into a framework to conceptualize the mechanisms underlying both avoidance and adherence in this population. As such, ACT has the potential to serve as a conceptual underpinning of a psychological intervention to help men reduce avoidance to penile injections and adhere to an ER program. PMID:25707812

Surgical planning for radical prostatectomies using three-dimensional visualization and a virtual reality display system

Thousands of radical prostatectomies for prostate cancer are performed each year. Radical prostatectomy is a challenging procedure due to anatomical variability and the adjacency of critical structures, including the external urinary sphincter and neurovascular bundles that subserve erectile function. Because of this, there are significant risks of urinary incontinence and impotence following this procedure. Preoperative interaction with three-dimensional visualization of the important anatomical structures might allow the surgeon to understand important individual anatomical relationships of patients. Such understanding might decrease the rate of morbidities, especially for surgeons in training. Patient specific anatomic data can be obtained from preoperative 3D MRI diagnostic imaging examinations of the prostate gland utilizing endorectal coils and phased array multicoils. The volumes of the important structures can then be segmented using interactive image editing tools and then displayed using 3-D surface rendering algorithms on standard work stations. Anatomic relationships can be visualized using surface displays and 3-D colorwash and transparency to allow internal visualization of hidden structures. Preoperatively a surgeon and radiologist can interactively manipulate the 3-D visualizations. Important anatomical relationships can better be visualized and used to plan the surgery. Postoperatively the 3-D displays can be compared to actual surgical experience and pathologic data. Patients can then be followed to assess the incidence of morbidities. More advanced approaches to visualize these anatomical structures in support of surgical planning will be implemented on virtual reality (VR) display systems. Such realistic displays are `immersive,' and allow surgeons to simultaneously see and manipulate the anatomy, to plan the procedure and to rehearse it in a realistic way. Ultimately the VR systems will be implemented in the operating room (OR) to assist the

Peripheral nerve injury evokes a complex cascade of chemical reactions including generation of molecular radicals. Conversely, the reactions within nerve induced by stress are difficult to directly detect or measure to establish causality. Monitoring these reactions in vivo would enable deeper understanding of the nature of the injury and healing processes. Here, we utilized near-infrared fluorescence molecular probes delivered via intra-neural injection technique to enable live, in vivo imaging of tissue response associated with nerve injury and stress. These initially quenched fluorescent probes featured specific sensitivity to hydroxyl radicals and become fluorescent upon encountering reactive oxygen species (ROS). Intraneurally delivered probes demonstrated rapid activation in injured rat sciatic nerve but minimal activation in normal, uninjured nerve. In addition, these probes reported activation within sciatic nerves of living rats after a stress caused by a pinprick stimulus to the abdomen. This imaging approach was more sensitive to detecting changes within nerves due to the induced stress than other techniques to evaluate cellular and molecular changes. Specifically, neither histological analysis of the sciatic nerves, nor the expression of pain and stress associated genes in dorsal root ganglia could provide statistically significant differences between the control and stressed groups. Overall, the results demonstrate a novel imaging approach to measure ROS in addition to the impact of ROS within nerve in live animals. Copyright © 2016 Elsevier Inc. All rights reserved.

To determine the pharmacodynamic effects of Sonidegib (LDE-225) in prostate tumor tissue from men with high-risk localized prostate cancer, by comparing pre-surgical core-biopsy specimens to tumor tissue harvested post-treatment at prostatectomy. We conducted a prospective randomized (Sonidegib vs. observation) open-label translational clinical trial in men with high-risk localized prostate cancer undergoing radical prostatectomy. The primary endpoint was the proportion of patients in each arm who achieved at least a two-fold reduction in GLI1 mRNA expression in post-treatment versus pre-treatment tumor tissue. Secondary endpoints included the effect of pre-surgical treatment with Sonidegib on disease progression following radical prostatectomy, and safety. Fourteen men were equally randomized (7 per arm) to either neoadjuvant Sonidegib or observation for 4 weeks prior to prostatectomy. Six of seven men (86%) in the Sonidegib arm (and none in the control group) achieved a GLI1 suppression of at least two-fold. In the Sonidegib arm, drug was detectable in plasma and in prostatic tissue; and median intra-patient GLI1 expression decreased by 63-fold, indicating potent suppression of Hedgehog signaling. Sonidegib was well tolerated, without any Grade 3-4 adverse events observed. Disease-free survival was comparable among the two arms (HR = 1.50, 95% CI 0.26-8.69, P = 0.65). Hedgehog pathway activity (as measured by GLI1 expression) was detectable at baseline in men with localized high-risk prostate cancer. Sonidegib penetrated into prostatic tissue and induced a >60-fold suppression of the Hedgehog pathway. The oncological benefit of Hedgehog pathway inhibition in prostate cancer remains unclear.

Can TRUS Power Doppler Predict the Preservation of Erectile Function in HIFU Treatment of Localised Prostate Cancer? — A Preliminary Study

Perhaps the single most significant unifying feature in men diagnosed with organ confined prostate cancer is the hope of erectile preservation in the treatment that offers cure. Although it is not 100% certain that the preservation of neurovascular bundle (NVB) can actually lead to intact sexual function, there is evidence that non-sparing nerve radical prostatectomy has a much higher incidence of impotence compared to nerve-sparing ones. The idea to monitor NVB flow can be realized using a simple power Doppler technique that was done before and after HIFU. The NVB flow was found intact in all patients (n=14). Tumescence returned in 93% of patients with a mean time of 6 weeks for this to occur. The erectile function score, IIEF-15 decreased by a third but shows a trend towards recovery. This preliminary study demonstrates the feasibility of transrectal power Doppler as a monitoring tool to provide immediate feedback on the NVB flow which was found intact in all patients. Although early reports of the tumescence proved encouraging, its full impact on erectile function will require longer follow-up.

Role of Schwann cells in the regeneration of penile and peripheral nerves

Schwann cells (SCs) are the principal glia of the peripheral nervous system. The end point of SC development is the formation of myelinating and nonmyelinating cells which ensheath large and small diameter axons, respectively. They play an important role in axon regeneration after injury, including cavernous nerve injury that leads to erectile dysfunction (ED). Despite improvement in radical prostatectomy surgical techniques, many patients still suffer from ED postoperatively as surgical trauma causes traction injuries and local inflammatory changes in the neuronal microenvironment of the autonomic fibers innervating the penis resulting in pathophysiological alterations in the end organ. The aim of this review is to summarize contemporary evidence regarding: (1) the origin and development of SCs in the peripheral and penile nerve system; (2) Wallerian degeneration and SC plastic change following peripheral and penile nerve injury; (3) how SCs promote peripheral and penile nerve regeneration by secreting neurotrophic factors; (4) and strategies targeting SCs to accelerate peripheral nerve regeneration. We searched PubMed for articles related to these topics in both animal models and human research and found numerous studies suggesting that SCs could be a novel target for treatment of nerve injury-induced ED.

To compare acute normovolemic hemodilution versus low central venous pressure strategy versus conventional fluid management in reducing intraoperative estimated blood loss, hematocrit drop and need for blood transfusion in patients undergoing radical retropubic prostatectomy under general anesthesia. Patients undergoing radical retropubic prostatectomy under general anesthesia were randomized to conventional fluid management, acute normovolemic hemodilution or low central venous pressure (≤5 mmHg). Treatment effects on estimated blood loss and hematocrit change were tested in multivariable regression models accounting for surgeon, prostate size, and all two-way interactions. Ninety-two patients completed the study. Estimated blood loss (mean ± SD) was significantly lower with low central venous pressure (706 ± 362 ml) compared to acute normovolemic hemodilution (1103 ± 635 ml) and conventional (1051 ± 714 ml) groups (p = 0.0134). There was no difference between the groups in need for blood transfusion, or hematocrit drop from preoperative values. The multivariate model predicting estimated blood loss showed a significant effect of treatment (p = 0.0028) and prostate size (p = 0.0323), accounting for surgeon (p = 0.0013). In the model predicting hematocrit change, accounting for surgeon difference (p = 0.0037), the treatment effect depended on prostate size (p = 0.0007) with the slope of low central venous pressure differing from the other two groups. Hematocrit was predicted to drop more with increased prostate size in acute normovolemic hemodilution and conventional groups but not with low central venous pressure. Limitations include the inability to blind providers to group assignment, possible variability between providers in estimation of blood loss, and the relatively small sample size that was not powered to detect differences between the groups in need for blood transfusion.

Purpose: The addition of androgen deprivation therapy (ADT) to definitive external beam radiation therapy (RT) improves outcomes in higher-risk prostate cancer patients. However, the benefit of ADT with salvage RT in post-prostatectomy patients is not clearly established. Our study compares biochemical outcomes in post-prostatectomy patients who received salvage RT with or without concurrent ADT. Methods and Materials: Of nearly 2,000 post-prostatectomy patients, we reviewed the medical records of 191 patients who received salvage RT at University of Pennsylvania between 1987 and 2007. Follow-up data were obtained by chart review and electronic polling of the institutional laboratory database and Social Securitymore » Death Index. Biochemical failure after salvage RT was defined as a prostate-specific antigen of 2.0 ng/mL above the post-RT nadir or the initiation of ADT after completion of salvage RT. Results: One hundred twenty-nine patients received salvage RT alone, and 62 patients received combined ADT and salvage RT. Median follow-up was 5.4 years. Patients who received combined ADT and salvage RT were younger, had higher pathologic Gleason scores, and higher rates of seminal vesicle invasion, lymph node involvement, and pelvic nodal irradiation compared with patients who received salvage RT alone. Patients who received combined therapy had improved biochemical progression-free survival (bPFS) compared with patients who received RT alone (p = 0.048). For patients with pathologic Gleason scores {<=}7, combined RT and ADT resulted in significantly improved bPFS compared to RT alone (p = 0.013). Conclusions: These results suggest that initiating ADT during salvage RT in the post-prostatectomy setting may improve bPFS compared with salvage RT alone. However, prospective randomized data are necessary to definitively determine whether hormonal manipulation should be used with salvage RT. Furthermore, the optimal nature and duration of ADT and the patient subgroups

To explore the application of immediate recurrent laryngeal nerve reconstruction in the treatment of thyroid cancer invading the recurrent laryngeal nerve. Ten patients with thyroid cancer invading unilateral recurrent laryngeal nerve underwent radical surgery and immediate recurrent laryngeal nerve reconstruction. The reconstructive surgical approach included recurrent laryngeal nerve decompression surgery, end-to-end anastomosis of the recurrent laryngeal nerve, anastomosis of ansa cervicalis nerve to the recurrent laryngeal nerve, and nerve-muscle pedicle (NMP) technique. Among the ten patients, one underwent nerve decompression, one underwent end-to-end anastomosis of the recurrent laryngeal nerve, seven had anastomosis of ansa cervicalis to recurrent laryngeal nerve, and one case had anastomosis of ansa cervicalis to recurrent laryngeal nerve combined with nerve-muscle pedicle (NMP) technique. The effect of surgery was evaluated by videolaryngoscopy, maximum phonation time (MPT), phonation efficiency index (PEI) and voice assessment. T-test was used in the statistical analysis. All of the 10 patients had no complications including tumor recurrence and hypoparathyroidism after the surgery. Their hoarseness symptoms were improved, and the patients returned to normal or near-normal voice. Postoperative videolaryngoscopy showed that paralyzed vocal cord returned to normal muscle tone and volume, and the vocal cord vibration and mucosal wave were symmetric and the patients got good glottal closure. The pre- and post-operative maximum phone times of the patients were (4.52 ± 0.89) s and (11.91 ± 1.87) s, respectively (P < 0.01). The pre- and post-operative phonation efficiency indices were (1.37 ± 0.43) s/L and (4.02 ± 1.33) s/L, respectively (P < 0.05). In patients with thyroid cancer invading unilateral recurrent laryngeal nerve, immediate recurrent laryngeal nerve reconstruction following radical surgery of thyroid cancer can effectively achieve recovery in

Male stress urinary incontinence (SUI) after radical prostatectomy (RP) is common. The surgical standard of care traditionally has been placement of an artificial urinary sphincter (AUS) but since its introduction the transobturator male sling has been shown to have particular unique advantages. Our aim was to assess outcomes of a consecutive series of suburethral sling insertions in men presenting with all degrees of post RP SUI. A consecutive cohort of men undergoing AdVance sling insertion following RP were studied. Parameters assessed included pre and postoperative urinary function, 24 hour pad use, quality of life (QoL) outcomes, complications and further treatments. Degree of incontinence was categorized as mild (1-2), moderate (3-5) or severe (≥ 6) depending on daily pad use. Patients were reviewed at 1, 4 and 6 months. The International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) was used to assess symptom severity and QoL outcomes. Seventy-seven patients were included, mean age 68 and mean time to sling post RP 34 (8-113) months. Preoperative degree of incontinence: mild 22%, moderate 58%, severe 20%. Fourteen percent had undergone post RP radiation therapy (RT). In total 73% experienced complete resolution of symptoms post sling, 12% significant improvement, 15% no reduction in pad use. Sixty percent with severe incontinence were classified as cured (no pad or 1 dry pad for security reasons). When patients with preoperative RT were excluded, cure rate rose to 82%. On follow up survey at 30 months (mean), the ICIQ-SF score decreased from baseline 17.7 (9-21.0) to 8.0 (0-20) (p < 0.0001), CI 95% (8-12). Suburethral slings are effective and safe for all degrees of post RP incontinence, are associated with improved QoL parameters and with appropriate selection and counseling are a viable option for more severe degrees of post RP SUI.

Whether surgeons perform better utilising a robot-assisted laparoscopic technique compared with an open approach during prostate cancer surgery is debatable. To report erectile function and early oncologic outcomes for both surgical modalities, stratified by prostate cancer risk grouping. In a prospective nonrandomised trial, we recruited 2545 men with prostate cancer from seven open (n=753) and seven robot-assisted (n=1792) Swedish centres (2008-2011). Clinometrically-validated questionnaire-based patient-reported erectile function was collected before, 3 mo, 12 mo, and 24 mo after surgery. Surgeon-reported degree of neurovascular-bundle preservation, pathologist-reported positive surgical margin (PSM) rates, and 2-yr prostate-specific antigen-relapse rates were measured. Among 1702 preoperatively potent men, we found enhanced erectile function recovery for low/intermediate-risk patients in the robot-assisted group at 3 mo. For patients with high-risk tumours, point estimates for erectile function recovery at 24 mo favoured the open surgery group. The degree of neurovascular bundle preservation and erectile function recovery were greater correlated for robot-assisted surgery. In pT2 tumours, 10% versus 17% PSM rates were observed for open and robot-assisted surgery, respectively; corresponding rates for pT3 tumours were 48% and 33%. These differences were associated with biochemical recurrence in pT3 but not pT2 disease. The study is limited by its nonrandomised design and relatively short follow-up. Earlier recovery of erectile function in the robot-assisted surgery group in lower-risk patients is counterbalanced by lower PSM rates for open surgeons in organ-confined disease; thus, both open and robotic surgeons need to consider this trade-off when determining the plane of surgical dissection. Robot-assisted surgery also facilitates easier identification of nerve preservation planes during radical prostatectomy as well as wider dissection for pT3 cases. For

Summary Reconstruction of the middle third of the leg is a challenging procedure. The tibialis anterior muscle flap can be useful in reconstruction of the middle third of the leg with exposed tibia. The aim of this work was to evaluate the efficacy of tibialis anterior pivoted muscle flap for reconstruction of the middle third of the leg with functional preservation. This study, performed in the Plastic, Reconstructive and Burn Unit, Menoufiya University Hospital, Egypt, included 16 patients (13 males and 3 females) during the period February 2007/May 2010: seven post-burn and nine post-traumatic patients with post-burn middle-third leg defects with exposed tibia. Their ages ranged from 14 to 67 years. A function-sparing lateral split tibialis anterior pivoted muscle flap was used in all the patients. Follow-up ranged from six months to two years. Partial flap loss occurred in one patient (6.25%), there was no post-operative haematoma or infection, and only one case of wound dehiscence (6.25%), managed by secondary suture. No donor site morbidity or any significant functional impairment was observed, and the subjective aesthetic results were satisfactory. Lateral split tibialis anterior pivoted muscle flap is a useful, simple technique, allowing rapid, durable and reliable coverage of middle-third leg defects without significant impairment of function and without sacrificing major nerves or vessels in the foot, and without any donor site morbidity.

To assess the effects of a Pilates exercise program compared to conventional pelvic floor muscle training (PFMT) protocol on pelvic floor muscle strength (PFMS) in patients with post-prostatectomy urinary incontinence. Patients were randomized into three treatment groups (G1: Pilates, G2: electrical stimulation combined with PFMT, and G3: control group). Duration of therapy was 10 weeks. Baseline assessment included the 24 h pad-test and the ICI-Q questionnaire. PFMS was measured using a manometric perineometry device at baseline and 4 months after radical prostatectomy (RP). The level of significance was P < 0.05. One hundred twenty three patients were randomized and 104 patients completed the study protocol (G1: n = 34; G2: n = 35; G3: n = 35). Post-treatment assessment showed statistically significant improvements in maximum strength in G2, increased endurance in G1 and G2, and increment of muscle power in all three groups (P < 0.05). However, there were no significant differences in the mean changes of maximum strength, endurance, and muscle power between groups after treatment (P > 0.05). G1 and G2 achieved a higher number of fully continent patients than G3 (P < 0.05). At the end of treatment, 59% of patients in G1, 54% in G2, and 26% in G3 were continent (no pads/day). Improvements in PFMS parameters were distinct among active treatment groups versus controls, but did not predict recovery of urinary continence at final assessment. The Pilates method promoted similar outcomes in the proportion of fully continent patients when compared to conventional PFMT 4 months after RP. © 2017 Wiley Periodicals, Inc.

Ion channels are very important in the peripheral sensitization in neuropathic pain. Our present study aims to investigate the possible contribution of Ca V 3.2 T-type calcium channels in damaged dorsal root ganglion neurons in neuropathic pain. We established a neuropathic pain model of rats with spared nerve injury. In these model rats, it was easy to distinguish damaged dorsal root ganglion neurons (of tibial nerve and common peroneal nerve) from intact dorsal root ganglion neurons (of sural nerves). Our results showed that Ca V 3.2 protein expression increased in medium-sized neurons from the damaged dorsal root ganglions but not in the intact ones. With whole cell patch clamp recording technique, it was found that after-depolarizing amplitudes of the damaged medium-sized dorsal root ganglion neurons increased significantly at membrane potentials of -85 mV and -95 mV. These results indicate a functional up-regulation of Ca V 3.2 T-type calcium channels in the damaged medium-sized neurons after spared nerve injury. Behaviorally, blockade of Ca V 3.2 with antisense oligodeoxynucleotides could significantly reverse mechanical allodynia. These results suggest that Ca V 3.2 T-type calcium channels in damaged medium-sized dorsal root ganglion neurons might contribute to neuropathic pain after peripheral nerve injury.

Erectile Dysfunction after Radical Prostatectomy: Prevalence, Medical Treatments, and Psychosocial Interventions

Purpose of review This review will discuss erectile dysfunction (ED) in prostate cancer patients following radical prostatectomy (RP). It will focus on the prevalence and current treatments for ED as well as the emotional impact of ED and the current psychosocial interventions designed to help patients cope with this side effect. Recent findings While there is a large discrepancy in prevalence rates of ED after RP, several recent studies have cited rates as high as 85%. The concept of “penile rehabilitation” is now the standard of practice to treat ED following RP. However, many men avoid seeking help or utilizing ED treatments. This avoidance is related to the shame, frustration, and distress many men with ED and their partners experience. Recent psychosocial interventions have been developed to facilitate the use of treatments and help men cope with ED. These interventions have shown initial promise, however, continued intervention development is needed to reduce distress and improve long-term erectile function (EF) outcomes. Summary ED is a significant problem following prostate cancer surgery. While there are effective medical treatments, the development of psychosocial interventions should continue to evolve to maximize the assistance we can give to men and their partners. PMID:26808052

We conducted a questionnaire survey of hospitals with robot-assisted surgical equipment to study changes of the surgical case loads after its installation and the managerial strategies for its purchase. The study included 154 hospitals (as of April 2014) that were queried about their radical prostatectomy case loads from January 2009 to December 2013, strategies for installation of the equipment in their hospitals, and other topics related to the study purpose. The overall response rate of hospitals was 63%, though it marginally varied according to type and area. The annual case load was determined based on the results of the questionnaire and other modalities. It increased from 3,518 in 2009 to 6,425 in 2013. The case load seemed to be concentrated in hospitals with robot equipment since the increase of their number was very minimal over the 5 years. The hospitals with the robot treated a larger number of newly diagnosed patients with the disease than before. Most of the patients were those having localized cancer that was indicated for radical surgery, suggesting again the concentration of the surgical case loads in the hospitals with robots. While most hospitals believed that installation of a robot was necessary as an option for treatment procedures, the future strategy of the hospital, and other reasons, the action of the hospital to gain prestige may be involved in the process of purchasing the equipment. In conclusion, robot-assisted laparoscopic radical prostatectomy has become popular as a surgical procedure for prostate cancer in our society. This may lead to a concentration of the surgical case load in a limited number of hospitals with robots. We also discuss the typical action of an acute-care hospital when it purchases expensive clinical medical equipment.

Chemotherapy and novel therapeutics before radical prostatectomy for high-risk clinically localized prostate cancer.

Although both surgery and radiation are potential curative options for men with clinically localized prostate cancer, a significant proportion of men with high-risk and locally advanced disease will demonstrate biochemical and potentially clinical progression of their disease. Neoadjuvant systemic therapy before radical prostatectomy (RP) is a logical strategy to improve treatment outcomes for men with clinically localized high-risk prostate cancer. Furthermore, delivery of chemotherapy and other systemic agents before RP affords an opportunity to explore the efficacy of these agents with pathologic end points. Neoadjuvant chemotherapy, primarily with docetaxel (with or without androgen deprivation therapy), has demonstrated feasibility and safety in men undergoing RP, but no study to date has established the efficacy of neoadjuvant chemotherapy or neoadjuvant chemohormonal therapies. Other novel agents, such as those targeting the vascular endothelial growth factor receptor, epidermal growth factor receptor, platelet-derived growth factor receptor, clusterin, and immunomodulatory therapeutics, are currently under investigation.

Cigarette smoking has been consistently associated with increased risk of overall mortality, but the importance of smoking for patients with prostate cancer (CaP) who are candidates for curative radical prostatectomy (RP) has received less attention. This retrospectively designed cohort study investigated the association of smoking history at RP with subsequent CaP treatment outcomes and overall mortality. A total of 1981 patients who underwent RP at Roswell Park Cancer Institute (RPCI) between 1993 and 2014 were studied. Smoking history was considered as a risk factor for overall mortality as well as for currently accepted CaP treatment outcomes (biochemical failure, treatment failure, distant metastasis, and disease-specific mortality). The associations of smoking status with these outcomes were tested by Cox proportional hazard analyses. A total of 153 (8%) patients died during follow-up. Current smoking at diagnosis was a statistically significant predictor of overall mortality after RP (current smokers vs. former and never smokers, hazards ratio 2.07, 95% confidence interval [CI]: 1.36-3.14). This association persisted for overall mortality at 3, 5, and 10 years (odds ratios 2.07 [95% CI: 1.36-3.15], 2.05 [95% CI: 1.35-3.12], and 1.8 [95% CI: 1.18-2.74], respectively). Smoking was not associated with biochemical failure, treatment failure, distant metastasis, or CaP-specific mortality, and the association of smoking with overall mortality did not appear to be functionally related to treatment or biochemical failure, or to distant metastasis. Smoking is a non-negligible risk factor for death among CaP patients who undergo RP; patients who smoke are far more likely to die of causes other than CaP. © 2017 The Authors.

The goal of our study was to report on the feasibility of outpatient laparoscopic radical hysterectomy in patients with early-stage cervical cancer. We included all patients who underwent a laparoscopic radical hysterectomy at the Instituto de Cancerología - Las Americas in Medellin, Colombia, between January 2013 and July 2015. The control group was a similar cohort of patients who were admitted after their surgery. Seventy-six patients were included [outpatient (31) and admitted (45)]. There were no statistically significant differences between groups regarding age, clinical stage, histology, nodal count, need of adjuvant treatment, visual pain scores at discharge or follow up time. All patients underwent a transversus abdominis plane block. The median operative time was 150min (range, 105-240) in the outpatient group vs. 170min (range, 97-300) in the admitted group (p=0.023). The median estimated blood loss was 50ml (range, 20-150) in the outpatient group vs. 120ml (range, 20-1000) in the admitted group (p=0.001). All patients were able to void spontaneously and tolerate a diet before discharge. In patients who were admitted, the median hospital stay was 1day, (range; 1-6), and 39 (87%) were discharged at postoperative day 1. There were 6 postoperative complications, 3 in each group. There were no recurrences in the follow-up period in the outpatient group, and there were 3 (6.6%) recurrences in the admitted group. Outpatient laparoscopic radical hysterectomy is feasible and can be performed safely in a developing country in well-selected patients. Copyright © 2016. Published by Elsevier Inc.

To develop a Web-based audiovisual telementoring system for robot-assisted radical prostatectomy (RARP) and to assess the utility of this system. A telementoring system for RARP, consisting of a 3-dimensional high-definition view of the operating field, overview of the operating room, annotation function, and 2-channel audio feed with bidirectional connectivity between 2 institutions, was developed. The outcome of RARP performed for the initial 30 patients by 2 surgeons with telementoring was compared with that for 2 surgeons who received direct mentoring. This system was shown to function properly with an acceptable latency. There were no significant differences in several parameters reflecting surgical outcomes, including the operating time, complication rate, early continence status, and positive margin rate between the telementoring and direct mentoring groups. These findings suggest the usefulness of the telementoring system for promoting the spread of precise surgical techniques associated with RARP. To our knowledge, this is the first report concerning telementoring for robot-assisted surgery. Copyright © 2014 Elsevier Inc. All rights reserved.

Whether or not sacrificing accessory pudendal arteries (APAs) during radical prostatectomy affects potency has been an ongoing source of concern. Herein, we present our potency results relative to sacrificing APAs in normally pre-potent men following robot-assisted radical prostatectomy (RARP). The distribution of APAs and clinical characteristics were prospectively recorded in 200 consecutive patients undergoing RARP with a cautery-free technique. Sexual function was assessed using the International Index of Erectile Function 5-item questionnaire (IIEF-5). All APAs were sacrificed due to stapling the dorsal vein complex. Postoperatively, potency was defined by an affirmative answer to the following two questions: "Were erections adequate for penetration?" and "were the erections satisfactory?" Postoperative IIEF-5 scores and quality of erections (% of preoperative firmness: 0%, 25%, 50%, 75%, 100%) were also obtained. Subgroup analysis of patients age < or =65 years with IIEF-5 score of 22-25 was performed. Eighty patients (40%) had APAs. Preoperatively, there was no association with having an APA and normal/abnormal sexual function. Preoperatively, 58/200 were < or =65 years with self-administered IIEF-5 scores of 22-25. Postoperatively, 53/58 (91%) were potent at 24 months follow-up. Nineteen of 58 patients had a sacrificed APA; 39 patients had no APA. Eighteen of 19 (95%) patients with sacrificed APAs were potent vs. 35/39 (90%) with no APA present (P = 0.53). Multivariate analysis showed no significant correlation between sacrificing an APA and time of potency recovery, quality of postoperative erections (94% vs. 90% P = 0.80) or mean IIEF-5 score (22.4 vs. 20.8, P = 0.13). We found no correlation between the presence or absence of APAs and preoperative sexual function. Furthermore, after sacrificing all APAs, we found no correlation with potency return, time to return of potency, quality of erections, or mean IIEF-5 scores at 24 months.

Urinary incontinence is one of the most commonly reported and distressing side effects of radical prostatectomy for prostate carcinoma. Several studies have suggested that symptoms may be worse in obese men but to our knowledge no research has addressed the joint effects of obesity and a sedentary lifestyle. We evaluated the association of obesity and lack of physical activity with urinary incontinence in a sample of men who had undergone radical prostatectomy. Height and weight were abstracted from charts, and obesity was defined as body mass index 30 kg/m(2) or greater. Men completed a questionnaire before surgery that included self-report of vigorous physical activity. Men who reported 1 hour or more per week of vigorous activities were considered physically active. Men reported their incontinence to the surgeon at their urology visits. Information on incontinence was abstracted from charts at 6 and 58 weeks after surgery. At 6 weeks after surgery 59% (405) of men were incontinent, defined as any pad use. At 58 weeks after surgery 22% (165) of men were incontinent. At 58 weeks incontinence was more prevalent in men who were obese and physically inactive (59% incontinent). Physical activity may offset some of the negative consequences of being obese because the prevalence of incontinence at 58 weeks was similar in the obese and active (25% incontinent), and nonbese and inactive (24% incontinent) men. The best outcomes were in men who were nonobese and physically active (16% incontinent). Men who were not obese and were active were 26% less likely to be incontinent than men who were obese and inactive (RR 0.74, 95% CI 0.52-1.06). Pre-prostatectomy physical activity and obesity may be important factors in post-prostatectomy continence levels. Interventions aimed at increasing physical activity and decreasing weight in patients with prostate cancer may improve quality of life by offsetting the negative side effects of treatment.

Early salvage radiotherapy (eSRT) represents the only curative option for prostate cancer patients experiencing biochemical recurrence (BCR) for local recurrence after radical prostatectomy (RP). To develop and internally validate a novel nomogram predicting BCR after eSRT in patients treated with RP. Using a multi-institutional cohort, 472 node-negative patients who experienced BCR after RP were identified. All patients received eSRT, defined as local radiation to the prostate and seminal vesicle bed, delivered at prostate-specific antigen (PSA) ≤ 0.5 ng/ml. BCR after eSRT was defined as two consecutive PSA values ≥ 0.2 ng/ml. Uni- and multivariable Cox regression models predicting BCR after eSRT were fitted. Regression-based coefficients were used to develop a nomogram predicting the risk of 5-yr BCR after eSRT. The discrimination of the nomogram was quantified with the Harrell concordance index and the calibration plot method. Two hundred bootstrap resamples were used for internal validation. Mean follow-up was 58 mo (median: 48 mo). Overall, 5-yr BCR-free survival rate after eSRT was 73.4%. In univariable analyses, pathologic stage, Gleason score, and positive surgical margins were associated with the risk of BCR after eSRT (all p ≤ 0.04). These results were confirmed in multivariable analysis, where all the previously mentioned covariates as well as pre-RT PSA were significantly associated with BCR after eSRT (all p ≤ 0.04). A coefficient-based nomogram demonstrated a bootstrap-corrected discrimination of 0.74. Our study is limited by its retrospective nature and use of BCR as an end point. eSRT leads to excellent cancer control in patients with BCR for presumed local failure after RP. We developed the first nomogram to predict outcome after eSRT. Our model facilitates risk stratification and patient counselling regarding the use of secondary therapy for individuals experiencing BCR after RP. Salvage radiotherapy leads to optimal cancer control in

Surgical approach for radical prostatectomy is even today a subject of debate in the urologic community. Many comparative studies between retropubic and laparoscopic approach (robotic assisted or not) were reported since 10 years without being able to decide between the supporters of retropubic or laparoscopic approach. The committee of cancer research of the French urological association took hold this question after a recent meta-analysis publication on this subject. Although imperfect, this meta-analysis exists and permits to conclude partially on the advantages and the inconveniences supposed for each surgical approach. Regarding morbidity after radical prostatectomy, the only significant difference reported concerns the hemorrhagic risk in favour of the laparoscopic approach. Regarding oncologic results, the only exploitable data concern positive surgical margins rate, which is identical whatever surgical approach. Concerning the functional results, no difference was reported in the literature between different surgical approaches. Copyright © 2010 Elsevier Masson SAS. All rights reserved.

To assess the prognostic value of new Gleason grade grouping system in high-risk prostate cancer patients, we compared oncological outcomes after radical prostatectomy for patients with Gleason score 8 versus 9-10. Between 1987 and 2008, 3,755 men underwent radical prostatectomy with curative intent at University of Southern California. Patients who had Gleason score 8-10 at final histopathological evaluation (pT2-4N0) were included in this study. Eligible patients were divided into two groups; 226 with Gleason score 8 and 132 with Gleason score 9-10. Various patient and disease characteristics as well as oncological outcomes (biochemical recurrence, clinical recurrence, and overall survival) were compared between the groups. Impact of Gleason score on outcomes was controlled for preoperative prostate specific antigen, pathological stage, use of adjuvant radiotherapy, and neoadjuvant/adjuvant hormone therapy in multivariable analyses. A total of 358 patients (mean age: 65 years) were included in the analysis. Mean age and median duration of follow-up (9.6 years) were comparable between the study groups. Gleason 9-10 prostate cancer was associated with worse biochemical (HR 1.6; 95%CI [1.1-2.3]) and clinical recurrence free survival (HR = 1.9; 95%CI [1.1-3.3]); however, overall survival did not differ significantly between the groups. In addition, more patients with Gleason score 9-10 received adjuvant hormone therapy in the course of disease. Long-term follow-up after radical prostatectomy revealed significant differences in disease-specific outcomes between patients with Gleason score 8 versus 9-10. This sub-classification of high-risk patients might be helpful for patient counseling and determining therapeutic strategies.

2004-03-01

We performed a global self-assessment of continence following radical retropubic prostatectomy (RRP) and determined how this global self-assessment of continence correlates with commonly used definitions of continence. Between October 2000 and February 2002 all men who underwent RRP were encouraged to complete the University of California-Los Angeles Prostate Cancer Index 3, 6, 12 and 24 months postoperatively. Beginning October 2002 a single question capturing the patient global self-assessment of continence status was added to the postoperative continence assessment. The study design was cross-sectional since only continence surveys submitted between October 2002 through February 2003 were evaluated. Sensitivity, specificity and kappa coefficient was determined for the relationship between the patient global assessment of continence vs the definition of continence based on pad requirement, problem due to incontinence and frequency of incontinence. Continence progressively improved 3 to 24 months following RRP for all continence outcomes. At 24 months following RRP 97.1% of men considered themselves continent, while 97.1%, 94.1% and 97.1% were considered continent using continence definitions, including the requirement of no or 1 pad in a 24-hour interval, no or slight bother due to incontinence and total control or occasional dribbling, respectively. Our 3 definitions of continence derived from responses to the University of California-Los Angeles Prostate Cancer Index had excellent agreement with patient global self-assessment of continence (kappa coefficients between 0.76 and 0.83). The majority of men achieve continence without invasive intervention following RRP. Final continence status should be ascertained at 24 months. The patient global assessment of continence provides face validity for other definitions of continence based on responses to validated self-administered questionnaires.

Purpose Men with apparently localized prostate cancer often relapse years after radical prostatectomy (RP). We sought to determine if epithelial-like cells identified from bone marrow (BM) in patients after RP (commonly called disseminated tumor cells, DTC) were associated with biochemical recurrence (BR). Experimental Design We obtained BM aspirates from 569 men prior to RP and from 34 healthy men with PSA<2.5 ng/ml to establish a comparison group. Additionally, an analytic cohort consisting of 98 patients after RP with no evidence of disease (NED) was established to evaluate the relationship between DTC and BR. Epithelial cells in the BM were detected by magnetic bead enrichment with antibodies to CD45 and CD61 (negative selection) followed by antibodies to human epithelial antigen (positive selection) and confirmation with FITC-labeled anti-BerEP4 antibody. Results DTC were present in 72% (408/569) of patients prior to RP. There was no correlation with pathologic stage, Gleason grade, or pre-operative PSA. Three of 34 controls (8.8%) had DTC present. In patients NED post-RP, DTC were present in 56/98 (57%). DTC were detected in 12/14 (86%) NED patients post-RP who subsequently suffered BR. Presence of DTC in NED patients was an independent predictor of recurrence (HR 6.9, CI 1.03–45.9). Conclusions Approximately 70% of men undergoing RP had DTC detected in their BM prior to surgery, suggesting that these cells escape early in the disease. Though pre-operative DTC status does not correlate with pathologic risk factors, persistence of DTC after RP in NED patients was an independent predictor of recurrence. PMID:19147774

To identify the ability of multiple variables to predict prostate cancer specific mortality (PCSM) in a whole of population series of all radical prostatectomies (RP) performed in Victoria, Australia. A total of 2154 open RPs were performed in Victoria between July 1995 and December 2000. Subjects without follow up data, Gleason grade, pathological stage were excluded as were those who had pT4 disease or received neoadjuvant treatment. 1967 cases (91.3% of total) met the inclusion criteria for this study. Tumour characteristics were collated via a central registry. We used competing hazards regression models to investigate associations. At median follow up of 10.3 years pT stage of RP (P < 0.001) and high Gleason score of the RP specimen (P < 0.001 for ≥8 [Subhazard ratio (SHR) 11.19] and 4 + 3 = 7 [SHR 7.10]) compared with Gleason score 6 disease were strong predictors of progression to PCSM. Gleason score 3 + 4 = 7 was not at this time a significant predictor of PCSM (P = 0.08, SHR 1.84). Predictors of PCSM, independent of stage and grade, included rural residency (P = 0.003), primary surgeon contributing less than 40 cases (low-volume) to the VRPR (P = 0.025) and the involvement of a trainee surgeon in the operation (P = 0.031). The significant prediction of PCSM by pT cancer stage, Gleason score and primary Gleason pattern at RP in this whole of population study suggests a need to avoid understaging/grading in the process of cancer diagnosis and active surveillance protocols. Multi-modality therapy is likely to have a greater impact on PCSM in higher stage and Gleason grade disease. Identification of increased PCSM with rural residency and with involvement of a trainee urologist, and reduction in PCSM with higher surgeon volume all suggest potential for improved PC outcomes to be achieved with changes to surgical training and service delivery. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

To report on the establishment of a unified, electronic patient-reported outcome (PRO) infrastructure and pilot results from the first 5 practices enrolled in the web-based collection system developed by the Michigan Urological Surgery Improvement Collaborative. Eligible patients were those undergoing radical prostatectomy of 5 academic and community practices. PRO was obtained using a validated 21-item web-based questionnaire, regarding urinary function, erection function, and sexual interest and satisfaction. Data were collected preoperatively, at 3 months, and 6 months postoperatively. Patients were provided a link via email to complete the surveys. Perioperative and PRO data were analyzed as reports for individual patients and summary performance reports for individual surgeons. Among 773 eligible patients, 688 (89%) were enrolled preoperatively. Survey completion rate was 88%, 84%, and 90% preoperatively, at 3 months, and 6 months. Electronic completion rates preoperatively, at 3 months, and 6 months were 70%, 70%, and 68%, respectively. Mean urinary function scores were 18.3, 14.3, and 16.6 (good function ≥ 17), whereas mean erection scores were 18.7, 7.3, and 9.1 (good erection score ≥ 22) before surgery, at 3 months, and 6 months. Variation was noted for erectile function among the practices. Collection of electronic PRO via this unified, web-based format was successful and provided results that reflect expected recovery and identify opportunities for improvement. This will be extended to more practices statewide to improve outcomes after radical prostatectomy. Copyright © 2017 Elsevier Inc. All rights reserved.

To evaluate the influence of preservation of the muscular internal sphincter and proximal urethra on continence recovery after radical prostatectomy. This was a prospective single-center, case-control study. A total of 40 consecutive patients with organ-confined prostate cancer were submitted to radical prostatectomy with the preservation of the muscular internal sphincter and the proximal urethra (group 1), and their outcomes were compared with those of 40 patients submitted to a standard procedure (group 2). Continence rates were assessed using a self-administrated questionnaire at 3, 7 and 30 days, and 3 and 12 months after removal of the catheter. Group 1 had a faster recovery of early continence than group 2 at day 3 (45% vs 22%; P = 0.029) and at day 7 (75% vs 50%; P = 0.018). Considering the number of pads, group 1 had a faster recovery of continence at 3, 7 and 30 days, and also had less incidence of severe incontinence. There was no statistically significant difference in terms of continence at 3 and 12 months among the two groups. Multivariate logistic regression analysis showed that surgical technique and young age were significantly associated with earlier time to continence at 3 and 7 days. The two groups had no significant differences in terms of surgical margins. Our modified technique of radical retropubic prostatectomy with preservation of the smooth muscular internal sphincter, as well as of the proximal urethra during bladder neck dissection, results in a significantly increased urinary continence at 3, 7 and 30 days after catheter removal, with a minor incidence of severe incontinence. The technique is also oncologically safe, and it does not increase the operative duration of the procedure. © 2013 The Japanese Urological Association.

Influence of radical prostatectomy for prostate cancer on work status and working life 3 years after surgery.

The purpose of this study is to study the influence of radical prostatectomy (RP) for prostate cancer on work status and working life in men 3 years after surgery. In a prospective, questionnaire-based study on adverse effects after RP, 330 prostate cancer (PCa) patients who had been active in the workforce before RP described their work status 3 years after having surgery. We dichotomized their postoperative work status into "unchanged or increased" versus "reduced." The participants also reported whether their working life was influenced by the PCa trajectory to no, some, or a great extent. Univariate and multiple logistic regression models were established with sociodemographic and clinical characteristics as independent variables and "work status" or "influence of PCa trajectory on working life" as dependent variables. Twenty-five percent of the participants had retired. Of the remaining participants, approximately 20 % had a reduced work status, which in the multivariate analyses was significantly associated with increasing age. One third of the men still active in the workforce considered the PCa to negatively influence their working life. This was independently associated with bother related to urinary leakage, fatigue, and having undergone additional oncological therapy (pelvic radiotherapy and/or hormone treatment). Though RP does not affect work status in most men, approximately one third of them experience problems in their working life due to adverse effects related to RP and/or additional post-RP anti-cancer therapy. Most PCa survivors can expect to remain in the workforce for at least 3 years after RP, but for some, persistent adverse effects after RP and /or additional anti-cancer treatment negatively affect their working life. Pre-RP counseling of men within the workforce should cover possible post-RP changes concerning work status and working life.

Whole mount processing is more resource intensive than routine systematic sampling of radical retropubic prostatectomy specimens. We compared whole mount and systematic sampling for detecting pathological outcomes, and compared the prognostic value of pathological findings across pathological methods. We included men (608 whole mount and 525 systematic sampling samples) with no prior treatment who underwent radical retropubic prostatectomy at Vanderbilt University Medical Center between January 2000 and June 2008. We used univariate and multivariate analysis to compare the pathological outcome detection rate between pathological methods. Kaplan-Meier curves and the log rank test were used to compare the prognostic value of pathological findings across pathological methods. There were no significant differences between the whole mount and the systematic sampling groups in detecting extraprostatic extension (25% vs 30%), positive surgical margins (31% vs 31%), pathological Gleason score less than 7 (49% vs 43%), 7 (39% vs 43%) or greater than 7 (12% vs 13%), seminal vesicle invasion (8% vs 10%) or lymph node involvement (3% vs 5%). Tumor volume was higher in the systematic sampling group and whole mount detected more multiple surgical margins (each p <0.01). There were no significant differences in the likelihood of biochemical recurrence between the pathological methods when patients were stratified by pathological outcome. Except for estimated tumor volume and multiple margins whole mount and systematic sampling yield similar pathological information. Each method stratifies patients into comparable risk groups for biochemical recurrence. Thus, while whole mount is more resource intensive, it does not appear to result in improved detection of clinically important pathological outcomes or prognostication.

We retrospectively analysed 156 consecutive patients who had RRPs between June 2003 and May 2004 to determine the incidence of urinary retention after early catheter removal, with no cystogram or using an alpha-blocker. The mean age of the men was 60 years and 99% were clinical stage T1 or T2; 74% had their catheters removed 8 days after RRP. The incidence of urinary retention was 1.3%, and of haematuria requiring catheter replacement 2.6%. Two patients (1.3%) developed a bladder neck contracture. In the present study removing an indwelling catheter 1 week after RRP was safe, with a minimal risk of urinary retention or bladder neck contracture. The addition of an alpha-blocker is unlikely to reduce the already low incidence of urinary retention.

Paravertebral block, pectoral nerve (Pecs) block and wound infiltration are three modalities for post-operative analgesia following breast surgery. This study compares the analgesic efficacy of these techniques for post-operative analgesia. Sixty-five patients with American Society of Anesthesiologists' physical status 1 or 2 undergoing modified radical mastectomy with axillary dissection were recruited for the study. All patients received 21 mL 0.5% bupivacaine with adrenaline in the technique which was performed at the end of the surgery prior to extubation. Patients in Group 1 (local anaesthetic [LA], n = 22) received infiltration at the incision site after surgery, Group 2 patients (paravertebral block [PVB], n = 22) received ultrasound-guided ipsilateral paravertebral block while Group 3 patients [PECT] ( n = 21) received ultrasound-guided ipsilateral Pecs blocks I and II. Patients were evaluated for pain scores at 0, 2, 4, 6, 12 and 24 h, duration of post-operative analgesia and rescue analgesic doses required. Non-normally distributed data were analysed using the Kruskal-Wallis test and Analysis of variance for normal distribution. The post-operative visual analogue scale scores were lower in PVB group compared with others at 0, 2, 4, 12 and 24 h ( P < 0.05). Mean duration of analgesia was significantly prolonged in PVB group ( P < 0.001) with lesser rescue analgesic consumption up to 24 h. Ultrasound-guided paravertebral block reduces post-operative pain scores, prolongs the duration of analgesia and decreases demands for rescue analgesics in the first 24 h of post-operative period compared to ultrasound-guided Pecs block and local infiltration block.

To investigate the association between Agent Orange (AO) exposure and long-term prostate cancer (PC) outcomes. Data from 1,882 men undergoing radical prostatectomy for PC between 1988 and 2011 at Veterans Affairs Health Care Facilities were analyzed from the Shared Equal Access Regional Cancer Hospital database. Men were stratified by AO exposure (binary). Associations between AO exposure and biopsy and pathologic Gleason sum (GS) and pathologic stage were determined by logistic regression models adjusted for preoperative characteristics. Hazard ratios for biochemical recurrence (BCR), secondary treatment, metastases, and PC-specific mortality were determined by Cox models adjusted for preoperative characteristics. There were 333 (17.7%) men with AO exposure. AO-exposed men were younger (median 59 vs. 62 y), had lower preoperative prostate-specific antigen levels (5.8 vs. 6.7 ng/ml), lower clinical category (25% vs. 38% palpable), and higher body mass index (28.2 vs. 27.6 kg/m(2)), all P<0.01. Biopsy GS, pathologic GS, positive surgical margins, lymph node positivity, and extracapsular extension did not differ with AO exposure. At a median follow-up of 85 months, 702 (37.4%) patients had BCR, 603 (32.2%) patients received secondary treatment, 78 (4.1%) had metastases, and 39 (2.1%) died of PC. On multivariable analysis, AO exposure was not associated with BCR, secondary treatment, metastases, or PC mortality. AO exposure was not associated with worse preoperative characteristics such as elevated prostate-specific antigen levels or biopsy GS nor with BCR, secondary treatment, metastases, or PC death. Thus, as data on AO-exposed men mature, possible differences in PC outcomes observed previously are no longer apparent. Copyright © 2015 Elsevier Inc. All rights reserved.

To examine the Centers for Medicare and Medicaid Services, which since 2008 has identified and not reimbursed 10 common postoperative complications deemed "never events" or hospital-acquired conditions (HACs). Prostate cancer, the most frequent cancer among U.S. men, is most often treated with radical prostatectomy (RP). Therefore, its complications in total may represent significant costs to hospitals and providers if not reimbursed. We evaluated the potential effect of these unreimbursed HACs following RP on clinical outcomes and costs. Using the Nationwide Inpatient Sample, we selected a weighed, national, estimated sample of 451,707 men with prostate cancer who underwent RP between 2002 and 2009. Baseline sociodemographic and hospital characteristics are described. We calculated estimated frequencies and costs of HACs and the predictors of in-hospital mortality, prolonged length of stay, and increased total hospital costs. Overall, HACs were infrequent at 0.08%, with pressure ulcer development (0.02%) and foreign object retained at surgery (0.02%) being the most common. HAC occurrence was not affected by hospital teaching status or surgical volume, but larger hospital size was related to more HACs. Those experiencing an HAC were much more likely to have a prolonged length of stay (odds ratio = 6.68, 95% CI: 5.34-8.36) and increased hospital costs (odds ratio = 5.03, 95% CI: 4.05-6.24). HACs after RP cost an estimated nearly $1 million annually in the United States. In a robust sample of patients who underwent RP in the United States, HACs were very uncommon and contributed approximately $1 million in additional expenditures. As the U.S. government continues to expand quality improvement programs and develop incentives to avoid complications, efforts to monitor unnecessary complications should continue as well.

The relationship between urological and psychosocial variables, and generic quality of life in patients operated on for post-prostatectomy incontinence has hardly been studied, and our aim was to investigate this relationship. Patients who had an artificial urinary sphincter AMS800 (n = 100) implanted between January 2002 and June 2010 were invited to complete a mailed questionnaire covering demographic data including work ability, urinary and sexual function, anxiety/depression, and generic quality of life. Poor quality of life was defined as a score <40 on either the physical or the mental Short Form 12 summary scales. Of 85 compliant patients, 30 (35%) reported poor generic quality of life and 55 (65%) reported better quality of life at a median follow-up time of 26 months (range 6-104 months). The poor quality of life group showed significantly more overall urinary and sexual problems, and more men had undergone surgical revisions compared with the better quality of life group. Levels of anxiety and depression were significantly higher, and work ability was lower in the poor quality of life group. In multivariate logistic regression models, increased level of depression and impaired work ability, inability to reach orgasm, and not recommending the operation remained significantly associated with poor quality of life. Poor generic quality of life after surgery for post-prostatectomy incontinence is more strongly associated with reduced work ability and depression rather than urinary and sexual problems. © 2013 The Japanese Urological Association.

To evaluate the protection of urinary function after laparoscopic radical resection with pelvic autonomic nerve preservation (PANP) for rectal cancer. Prospectively 139 patients with middle or low rectal cancer receiving surgery during November 2005 to October 2007 were divided into two groups (L-PANP, n = 63; O-PANP, n = 76). The radicalism and safety of L-PANP surgery were analyzed and the effects upon urinary function between the two groups assessed by follow-ups and urodynamic study. Patients receiving subtypes I and II of L-PANP surgery had less decrease in contraction of bladder than those receiving the same subtype of O-PANP surgery at 10 days post-operation (Z = -2.358, P = 0.018; Z = -2.268, P = 0.033). And no difference was observed in patients receiving subtype III PANP surgery (Z = -1.302, P = 0.237). However, no matter which subtype of PANP surgery, patients of L-PANP group had a better contraction of bladder than those of O-PANP group at 1 month post-operation (P < 0.05). The 1-year survival rate was 98.0% (50/51) in L-PANP group and 96.6% (57/59) in O-PANP group. And no statistical difference was found between them (P = 0.898). Meanwhile, the 1-year relapse rate of pelvic cavity was 3.9% (2/52) in L-PANP group and 5.1% (3/59) in O-PANP group. And no statistical difference was found between them (P = 0.867). As compared with O-PANP surgery, L-PANP surgery shows a superiority in protection of urinary function.

Recent studies have shown promising results of neoadjuvant therapy in prostate cancer (PC). The aim of this study was to evaluate the potential of [11C]Choline PET/CT in therapy response monitoring after combined neoadjuvant docetaxel chemotherapy and complete androgen blockade in locally advanced and high risk PC patients. In [11C]Choline PET/CT there was a significant decrease of SUVmax and SUVmean (p = 0.004, each), prostate volume (p = 0.005) and PSA value (p = 0.003) after combined neoadjuvant therapy. MRI showed a significant prostate and tumor volume reduction (p = 0.003 and 0.005, respectively). Number of apoptotic cells was significantly higher in prostatectomy specimens of the therapy group compared to pretherapeutic biopsies and the control group (p = 0.02 and 0.003, respectively). 11 patients received two [11C]Choline PET/CT and MRI scans before and after combined neoadjuvant therapy followed by radical prostatectomy and pelvic lymph node dissection. [11C]Choline uptake, prostate and tumor volume, PSA value (before/after neoadjuvant therapy) and apoptosis (of pretherapeutic biopsy/posttherapeutic prostatectomy specimens of the therapy group and prostatectomy specimens of a matched control group without neoadjuvant therapy) were assessed and tested for differences and correlation using SPSS. The results showing a decrease in choline uptake after combined neoadjuvant therapy (paralleled by regressive and apoptotic changes in histopathology) confirm the potential of [11C]Choline PET/CT to monitor effects of neoadjuvant therapy in locally advanced and high risk PC patients. Further studies are recommended to evaluate its use during the course of neoadjuvant therapy for early response assessment.

With the advent of minimally invasive surgery (MIS) for treating urologic malignancies, emphasis has been placed on reducing patient morbidity and resuming normal activity. We sought to clarify whether open surgeons (OS) have modified their techniques, surgical equipment, and perioperative management in response to this trend. A survey sent to all members of the Society of Urologic Oncology assessed changes that OS performing radical retropubic prostatectomy have made in analgesia, operative technique, perioperative management, and follow-up patterns. We also assessed OS sense of competition from MIS. Surgeon perception of the influence MIS had on these changes was scored from 0 to 4 (0 = not at all, 1 = slightly, 2 = moderately, 3 = greatly, 4 =completely). Overall and major influence by MIS included scores 1-4 and 3-4, respectively. Reduced radical retropubic prostatectomy (RRP) case volume because of MIS competition was reported by 20 OS (24%), with 27 OS (32%) starting to perform MIS, and 20 (24%) doing mostly/exclusively MIS. MIS has influenced OS to reduce incision length (overall influence 56%/major influence 33%), operative time (40%/12%), blood loss (31%/17%), and transfusion rate (33%/14%). MIS has influenced OS to use new instruments (48%/44%) or loupes (20%/9%), modify dissection (45%/31%) or anastomotic technique (14%/12%), and increase the use of hemostatic agents (48%/19%). MIS has reduced convalescence in OS patients by reducing length of stay (52%/28%), time to a regular diet (40%/18%), duration of drain (21%/16%) and Foley (32%/15%), time to return to work (49%/25%), and exercise (44%/21%). MIS has changed follow-up of OS patients by increasing the use of clinical pathways (14%/9%) and validated questionnaires (22%/13%). To date, the influence of MIS on the OS has not been comprehensively assessed. This survey finds that OS report that MIS serves as major competition to the open technique and that it has influenced them to modify their surgical

To study the influence, in terms of prognosis, of the finding of seminal vesicle involvement in patients with prostate adenocarcinoma treated with radical prostatectomy. We reviewed a series of patients with seminal vesicle involvement with clinically localized prostate adenocarcinoma who underwent radical prostatectomy between 1989 and 2009, focusing on their clinical-pathological characteristics, biochemical progression-free survival (BPFS) and specific survival (SS). We assessed the variables that influenced BPFS and designed a risk model. A total of 127 out of 1,132 patients who underwent surgery (11%) presented seminal vesicle invasion (i.e., pT3b). In the multivariate study of the entire series (Cox model), pT3b affects the BPFS (HR: 2; 95% CI: 1.4-3.3; P=.001). Other influential factors were the affected borders, initial prostate-specific antigen levels, pathological Gleason score and the presence of palpated tumor. The pT3b tumors have poorer clinical-pathological variables when compared with pT2 and pT3a tumors. Sixty-five percent of the patients evidenced biochemical progression. The BPFS was significantly poorer for pT3b (40 ± 4% and 28 ± 4% at 5 and 10 years, respectively) than for pT2 and pT3a (P<.0001). The SS was also poorer in patients with pT3b tumors (91 ± 2% and 76 ± 4% at 5 and 10 years, respectively) (P<.0001). The predictors within the pT3b patient group were: PSA levels >10 ng/mL (HR: 1.9; 95% CI: 1.04-3.6; P=.04) and pathological Gleason score 8-10 (HR: 2.1; 95% CI: 1.2-3.5; P=.03). We designed a risk model that accounts for the variables involved, which entails 2 groups with different BPFS (P=.004): Group 1 (0-1 variable), with a BPFS of 46 ± 7% and 27 ± 8% at 5 and 10 years, respectively; and Group 2 (2 variables), with a BPFS of 14 ± 7% and 5 ± 5% at 5 and 10 years, respectively. Seminal vesicle involvement severely and negatively affects the BPFS and SS. We designed a risk model with the independent influential variables in BPFS

Although post-radical prostatectomy (RP) adjuvant radiation therapy (ART) benefits disease that is staged as pT3 or higher, the optimal ART timing remains unknown. Our objective is to characterize the outcomes and optimal timing of early vs. delayed ART. From the Surveillance, Epidemiology and End Results-Medicare data from 1995 to 2007, we identified 963 men with pT3N0 disease receiving early (<4 mo after RP, n = 419) vs. delayed (4-12 mo after RP, n = 544) ART after RP. Utilizing propensity score methods, we compared overall mortality, prostate cancer-specific mortality (PCSM), bone-related events (BRE), salvage hormonal therapy utilization, and intervention for urethral stricture. We then used the maximal statistic approach to determine at what time post-RP ART had the most significant effect on outcomes of interest in men with pT3N0 disease. When compared with delayed ART in men with pT3 disease, early ART was associated with improved PCSM (0.47 vs. 1.02 events per 100 person-years; P = 0.038) and less salvage hormonal therapy (2.88 vs. 4.59 events per 100 person-years; P = 0.001). Delaying ART beyond 5 months is associated with worse PCSM (hazard ratio [HR] 2.3; P = 0.020), beyond 3 months is associated with more BRE (HR 1.6; P = 0.025), and beyond 4 months is associated higher rates of salvage hormonal therapy (HR 1.6; P = 0.002). ART performed after 9 months was associated with fewer urethral strictures (HR 0.6; P = 0.042). Initiating ART less than 5 months after RP for pT3 is associated with improved PCSM. Early ART is also associated with fewer BRE and less use of salvage hormonal therapy if administered earlier than 3 and 4 months after RP, respectively. However, ART administered later than 9 months after RP is associated with fewer urethral strictures. Our population-based findings complement randomized trials designed with fixed ART timing. © 2013 Published by Elsevier Inc.

In this study we evaluate an ultrasensitive prostate specific antigen assay in patients with prostate cancer after radical prostatectomy to predict long-term biochemical recurrence-free survival. A total of 754 men who underwent radical prostatectomy and had an undetectable prostate specific antigen after surgery (less than 0.1 ng/ml) were studied. Prostate specific antigen was measured in banked serum specimens with an ultrasensitive assay (Hybritech® PSA, Beckman Coulter Access® 2) using a cutoff of 0.01 ng/ml. Prostate specific antigen was also measured in 44 men after cystoprostatectomy who had no pathological evidence of prostate cancer with the Hybritech assay and with the Quanterix AccuPSA™ assay. Of the 754 men 17% (131) experienced biochemical recurrence (median 4.0 years). Those men without biochemical recurrence (83%, 623) had a minimum of 5 years of followup (median 11). Prostate specific antigen was less than 0.01 ng/ml in 93.4% of men with no biochemical recurrence, whereas 30.5% of men with biochemical recurrence had a prostate specific antigen of 0.01 ng/ml or greater. On multivariate analysis postoperative prostate specific antigen at a 0.01 ng/ml cutoff, pathological stage and Gleason score, and surgical margins were significant independent predictors of biochemical recurrence risk. Kaplan-Meier estimates for mean biochemical recurrence-free survival were 15.2 years (95% CI 14.9-15.6) for prostate specific antigen less than 0.01 ng/ml and 10.0 years (95% CI 8.4-11.5) for prostate specific antigen 0.01 ng/ml or greater (p <0.0001). Biochemical recurrence-free rates 11 years after surgery were 86.1% (95% CI 83.2-89.0) for prostate specific antigen less than 0.01 ng/ml and 48.9% (95% CI 37.5-60.3) for prostate specific antigen 0.01 ng/ml or greater (p <0.0001). Prostate specific antigen concentrations in 44 men after cystoprostatectomy were all less than 0.03 ng/ml, with 95.4% less than 0.01 ng/ml. In men with a serum prostate specific antigen

Objective Fertility sparing surgery (FSS) is a strategy often considered in young patients with early epithelial ovarian cancer. We investigated the role and the outcomes of FSS in eEOC patients who underwent comprehensive surgery. Methods From January 2003 to January 2011, 24 patients underwent fertility sparing surgery. Eighteen were one-to-one matched and balanced for stage, histologic type and grading with a group of patients who underwent radical comprehensive staging (n=18). Demographics, surgical procedures, morbidities, pathologic findings, recurrence-rate, pregnancy-rate and correlations with disease-free survival were assessed. Results A total of 36 patients had a complete surgical staging including lymphadenectomy and were therefore analyzed. Seven patients experienced a recurrence: four (22%) in the fertility sparing surgery group and three (16%) in the control group (p=not significant). Sites of recurrence were: residual ovary (two), abdominal wall and peritoneal carcinomatosis in the fertility sparing surgery group; pelvic (two) and abdominal wall in the control group. Recurrences in the fertility sparing surgery group appeared earlier (mean, 10.3 months) than in radical comprehensive staging group (mean, 53.3 months) p<0.001. Disease-free survival were comparable between the two groups (p=0.422). No deaths were reported. All the patients in fertility sparing surgery group recovered a regular period. Thirteen out of 18 (72.2%) attempted to have a pregnancy. Five (38%) achieved a spontaneous pregnancy with a full term delivery. Conclusion Fertility sparing surgery in early epithelial ovarian cancer submitted to a comprehensive surgical staging could be considered safe with oncological results comparable to radical surgery group.

The 2009 International Society of Urological Pathology Consensus Conference in Boston made recommendations regarding the standardization of pathology reporting of radical prostatectomy specimens. Issues relating to the infiltration of tumor into the seminal vesicles and regional lymph nodes were coordinated by working group 4. There was a consensus that complete blocking of the seminal vesicles was not necessary, although sampling of the junction of the seminal vesicles and prostate was mandatory. There was consensus that sampling of the vas deferens margins was not obligatory. There was also consensus that muscular wall invasion of the extraprostatic seminal vesicle only should be regarded as seminal vesicle invasion. Categorization into types of seminal vesicle spread was agreed by consensus to be not necessary. For examination of lymph nodes, there was consensus that special techniques such as frozen sectioning were of use only in high-risk cases. There was no consensus on the optimal sampling method for pelvic lymph node dissection specimens, although there was consensus that all lymph nodes should be completely blocked as a minimum. There was also a consensus that a count of the number of lymph nodes harvested should be attempted. In view of recent evidence, there was consensus that the diameter of the largest lymph node metastasis should be measured. These consensus decisions will hopefully clarify the difficult areas of pathological assessment in radical prostatectomy evaluation and improve the concordance of research series to allow more accurate assessment of patient prognosis.

Background and Aims: Paravertebral block, pectoral nerve (Pecs) block and wound infiltration are three modalities for post-operative analgesia following breast surgery. This study compares the analgesic efficacy of these techniques for post-operative analgesia. Methods: Sixty-five patients with American Society of Anesthesiologists’ physical status 1 or 2 undergoing modified radical mastectomy with axillary dissection were recruited for the study. All patients received 21 mL 0.5% bupivacaine with adrenaline in the technique which was performed at the end of the surgery prior to extubation. Patients in Group 1 (local anaesthetic [LA], n = 22) received infiltration at the incision site after surgery, Group 2 patients (paravertebral block [PVB], n = 22) received ultrasound-guided ipsilateral paravertebral block while Group 3 patients [PECT] (n = 21) received ultrasound-guided ipsilateral Pecs blocks I and II. Patients were evaluated for pain scores at 0, 2, 4, 6, 12 and 24 h, duration of post-operative analgesia and rescue analgesic doses required. Non-normally distributed data were analysed using the Kruskal-Wallis test and Analysis of variance for normal distribution. Results: The post-operative visual analogue scale scores were lower in PVB group compared with others at 0, 2, 4, 12 and 24 h (P < 0.05). Mean duration of analgesia was significantly prolonged in PVB group (P < 0.001) with lesser rescue analgesic consumption up to 24 h. Conclusion: Ultrasound-guided paravertebral block reduces post-operative pain scores, prolongs the duration of analgesia and decreases demands for rescue analgesics in the first 24 h of post-operative period compared to ultrasound-guided Pecs block and local infiltration block.

To evaluate the feasibility of urinary catheter removal 10 days after a radical retropubic prostatectomy (RRP) by assessing the incidence of urinary extravasation and its effect on postoperative stricture and continence rates. During a 4.5-year period, 619 patients undergoing RRP were evaluated. If no extravasation was detected on gravity cystography, the urinary catheter was removed 10 days after RRP. In patients with significant extravasation the catheter was left in place for 3 weeks. Overall stricture and continence rates were recorded in patients at 3, 6 and 12 months after surgery. There was extravasation during cystography in 29 patients (4.6%). At 3, 6 and 12 months, continence rates after catheter removal at 10 days were 74.9%, 87.9%, and 93.6%, respectively, while in the late-removal group they were 72.4%, 84.6% and 90.9%, respectively, with no significant difference between the groups. At 3 months the overall continence rate was 74.8% and at 12 months up to 93.5%. There was no difference in stricture rates between the groups, with an overall stricture rate of 0.7%. Catheter removal 10 days after RRP is feasible, giving excellent early and late continence rates, with low anastomotic stricture rates obtained using good surgical technique. Extravasation at 10 days was rare and with proper management did not influence the final results.

Objective: This study was conducted to research the factors determining biochemical recurrence (BCR) in low-risk localized prostate cancer patients who underwent radical prostatectomy (RP). Materials and methods: We retrospectively analyzed the data of 504 patients who had undergone RP between 2003 and 2013 at our clinic. One hundred and fifty-two patients who underwent RP for low-risk prostate cancer were included in the study. Results: The mean follow-up period for patients was 58.7 (21–229) months. The mean age of the patients was 63.7±7.2 years (49–79). The mean prostate specific antigen (PSA) value was 5.25±4.22 ng/mL (3.58–9.45). The BCR rate after the operation was 25% (38/152). In the univariate analysis, recurrence determining factors were shown to include extracapsular involvement (ECI) (p=0.004), capsular invasion (CI) (p=0.001), age (p=0.014), and tumor size (p=0.006). However, only CI was found to be significant in multivariate analysis (p=0.001). Conclusion: Capsular invasion is an independent risk factor in low-risk prostate cancer patients who underwent RP for BCR. PMID:26328203

To study the feasibility of avoiding a urethral catheter after robotic radical prostatectomy by using suprapubic diversion with a urethral splint, as urethral catheterization is often a source of major discomfort and pain to the patient, and can cause more concern to the patient than the procedure; we present the outcomes of a pilot study. This pilot study involved 30 patients; in group 1 (the study group of 10 patients) we used a custom-made suprapubic catheter which provided a small anastomotic splint, multiple holes for drainage and the ability to retract the splint to give a voiding trial before removing the drainage device. Group 2 was a control group of 20 patients who had standard urethral catheterization with an 18 F Silastic Foley catheter. Demographic, intraoperative and outcome data were measured and analysed. Urethral symptoms were recorded using a specially developed questionnaire. The two groups were comparable in terms of age, serum prostate specific antigen level, body mass index, Gleason scores, tumour stage, operative duration, amount of bleeding, console times, anastomotic leakage and postoperative retention rates. The study group had significantly less penile shaft or tip pain and discomfort during walking or sleeping. No patient in either group had haematuria or clot retention requiring irrigation. Urethral catheter-less robotic radical prostatectomy is feasible. The advantages are decreased penile shaft and tip pain, and decreased patient discomfort and an earlier return of continence.

Complete embedding and close step-sectioning of radical prostatectomy specimens both increase detection of extra-prostatic extension, and correlate with increased disease-free survival by stage of prostate cancer patients.

The objectives of this work were to evaluate the efficacy of controlled close step-sectioned and whole-mounted radical prostatectomy specimen processing in prediction of clinical outcome as compared to the traditional processing techniques. Two-hundred and forty nine radical prostatectomy (RP) specimens were whole-mounted and close step-sectioned at caliper-measured 2.2-2.3 mm intervals. A group of 682 radical prostatectomy specimens were partially sampled as control. The RPs were performed during 1993-1999 with a mean follow-up of 29.3 months, pretreatment PSA of 0.1-40, and biopsy Gleason sums of 5-8. Disease-free survival based on biochemical or clinical recurrence and secondary intervention were computed using a Kaplan-Meier analysis. There were no significant differences in age at diagnosis, age at surgery, PSA at diagnosis, or biopsy Gleason between the two groups (P<0.05). Compared with the non-close step-sectioned group, the close step-sectioned group showed higher detection rates of extra-prostatic extension (215 (34.1%) vs, 128 (55.4%), P<0.01), and seminal vesicle invasion (50 (7.6%) vs 35 (14.7%), P<0.01). The close step-sectioned group correlated with greater 3-y disease-free survival in organ-confined (P<0.01) and specimen-confined (P<0.01) cases, over the non-uniform group. The close step-sectioned group showed significantly higher disease-free survival for cases with seminal vesicle invasion (P=0.046). No significant difference in disease-free survival was found for the positive margin group (P=0.39) between the close step-sectioned and non-uniform groups. The close step-sectioned technique correlates with increased disease-free survival rates for organ and specimen confined cases, possibly due to higher detection rates of extra-prostatic extension and seminal vesicle invasion. Close step-sectioning provides better assurance of organ-confined disease, resulting in enhanced prediction of outcome by pathological (TNM) stage.

Knowledge of preanalytic conditions that biospecimens are subjected to is critically important because novel surgical procedures, tissue sampling, handling, and storage might affect biomarker expression or invalidate tissue samples as analytes for some technologies. We investigated differences in RNA quality, gene expression by quantitative real-time PCR, and immunoreactive protein expression of selected prostate cancer biomarkers between tissues from retropubic radical prostatectomy (RRP) and robot-assisted laparoscopic prostatectomy (RALP). Sections of tissue microarray of 23 RALP and 22 RRP samples were stained with antibodies to androgen receptor (AR) and prostate-specific antigen (PSA) as intersite controls, and 14 other candidate biomarkers of research interest to three laboratories within the Australian Prostate Cancer BioResource tissue banking network. Quantitative real-time PCR was done for AR, PSA (KLK3), KLK2, KLK4, and HIF1A on RNA extracted from five RALP and five RRP frozen tissue cores. No histologic differences were observed between RALP and RRP tissue. Biomarker staining grouped these samples into those with increased (PSA, CK8/18, CKHMW, KLK4), decreased (KLK2, KLK14), or no change in expression (AR, ghrelin, Ki67, PCNA, VEGF-C, PAR2, YB1, p63, versican, and chondroitin 0-sulfate) in RALP compared with RRP tissue. No difference in RNA quality or gene expression was detected between RALP and RRP tissue. Changes in biomarker expression between RALP and RRP tissue exist at the immunoreactive protein level, but the etiology is unclear. Future studies should account for changes in biomarker expression when using RALP tissues, and mixed cohorts of RALP and RRP tissue should be avoided.

The advent of robotics has facilitated new surgical techniques for radical prostatectomy. These allow adjustment of pelvic anatomical and functional relationships after removal of the prostate to ameliorate postprostatectomy incontinence (PPI) and reduce the time to complete continence. To describe the results of a new surgical technique for reconstruction of vesicourethral anastomosis using the levator ani muscle for support during robot-assisted radical prostatectomy (RARP). A prospective, randomised, single-blind study among 66 consecutive patients with localised prostate cancer (cT1-2N0M0) undergoing RARP from June to September 2014, 32 using the new technique and 34 using the standard posterior reconstruction according to Rocco. In the advanced reconstruction of vesicourethral support (ARVUS) intervention group, the fibres of the levator ani muscle, Denonvilliers fascia, retrotrigonal layer, and median dorsal raphe were used to form the dorsal support for the urethrovesical anastomosis. Suture of the arcus tendineus to the bladder neck served as the anterior fixation. We compared demographic data and preoperative and postoperative functional and oncologic results for the two groups. The primary endpoint was continence evaluated at different time points (24h, 2, 4, and 8 wk, and 6 and 12 mo). The secondary endpoints were perioperative and postoperative complications and erectile function. Using a continence definition of 0 pads/d, the continence rates for the ARVUS versus the control group were 21.9% versus 5.9% at 24h (p=0.079), 43.8% versus 11.8% at 2 wk (p=0.005), 62.5% versus 14.7% at 4 wk (p<0.001), 68.8% versus 20.6% at 8 wk (p<0.001), 75.0% versus 44.1% at 6 mo (p=0.013), and 86.66% versus 61.29% at 12 mo (p=0.04). International Index of Erectile Function questionnaire results at 6 and 12 mo after surgery showed similar potency rates for the control group (40.0% and 73.33%) and the ARVUS group (38.8% and 72.22%). There were four postoperative

During standard, six-port set-up, robotic-assisted laparoscopic radical prostatectomy (RLRP) using a three-arm daVinci system (DVS), two assistants are routinely required. The role of the second assistant is often limited to isometric traction during prostate dissection. Due to muscle fatigue and inability of the operator to see the operative field, frequent repositioning of the second assistant is often required. In an attempt to improve efficiency in such surgical situations, we describe the use of the Endoholder, an adjustable articulating instrument holder, to assist during RLRP. During 100 consecutive cases, the Endoholder provided quick, reproducible retraction to facilitate exposure. No complications occurred with its use. The device reduced the need for a dedicated second assistant to stand bedside. We have achieved significant improvements in the safety and efficiency of retraction of the rectum, bladder, and prostate during RLRP with the Endoholder. For urologists working with a three-armed DVS, use of the Endoholder may help facilitate tissue retraction during dissection.

To determine the association between the anthropometric measurements by magnetic resonance imaging (MRI) and perioperative outcomes of extraperitoneal laparoscopic radical prostatectomy (ELRP). From 2008 to June 2016, 86 patients underwent preoperative MRI prior to undergoing ELRP for localized prostate cancer. We analyzed the associations between anthropometric measurements of MRI and the perioperative outcomes of patients who underwent ELRP. The mean patient age was 69.61±8.30 years. The medians of operating time and blood loss were 2.30 hours and 725.30ml, respectively. The total post-surgical complication rate was 1.16%. The median hospital stay was 6.50 days. The pathological stages for T2 and T3 were 45.74% and 34.04%, respectively. The rate as positive surgical margins (PSMs) was 18.09% (pT2 and pT3; 6.38% and 9.57%). The angles between pubic bone and prostate gland (angle 1&2), were significantly associated with operative time and hospital stay, respectively (p<0.05). There was no correlation between the pelvimetry and positive surgical margin. The findings of the present study suggest that anthropometric measurements of the MRI are related to operative difficulties in ELRP. This study confirmed that MRI planning is the key to preventing complications in ELRP. Copyright® by the International Brazilian Journal of Urology.

Transrectal ultrasound (TRUS) is a non-invasive approach to measure prostate size as a surrogate (density =1.0) for prostate weight with implications in prostate cancer prognosis. But the question is how reliable is this preoperative measurement compared to other measures of prostate weight. This work presents the correlations between preoperative TRUS prostate weight and prostate weight obtained after radical prostatectomy in 434 patients with mean TRUS weight 36g (range: 10g-120g) and the mean prostate weight obtained after radical prostatectomy 51g (range: 16g-180g) from the Northwestern University Prostate SPORE database. 311 patients with weight obtained by digital rectal exam (DRE) were also compared to the TRUS prostate weights with mean and range of DRE weights 33g (10g - 78g). Correlations were adjusted by age, BMI, an indicator variable for a pathological stage of III or greater, and for Gleason score greater than 7. Correlations were also computed for separately for European American and Other Race populations. Differences in means were evaluated via the paired t-test. Results indicate TRUS measures obtained via ultrasound as promising but improvement in the technology still appears needed.

Purpose: To investigate whether 3-T esla (3T) multiparametric endorectal MRI (erMRI) can add information to established predictors regarding occult extraprostatic or high-grade prostate cancer (PC) in men with clinically localized PC. Methods and Materials: At a single academic medical center, this retrospective study's cohort included 118 men with clinically localized PC who underwent 3T multiparametric erMRI followed by radical prostatectomy, from 2008 to 2011. Multivariable logistic regression analyses in all men and in 100 with favorable-risk PC addressed whether erMRI evidence of T3 disease was associated with prostatectomy T3 or Gleason score (GS) 8-10 (in patients with biopsy GS {<=}7)more » PC, adjusting for age, prostate-specific antigen level, clinical T category, biopsy GS, and percent positive biopsies. Results: The accuracy of erMRI prediction of extracapsular extension and seminal vesicle invasion was 75% and 95%, respectively. For all men, erMRI evidence of a T3 lesion versus T2 was associated with an increased odds of having pT3 disease (adjusted odds ratio [AOR] 4.81, 95% confidence interval [CI] 1.36-16.98, P=.015) and pGS 8-10 (AOR 5.56, 95% CI 1.10-28.18, P=.038). In the favorable-risk population, these results were AOR 4.14 (95% CI 1.03-16.56), P=.045 and AOR 7.71 (95% CI 1.36-43.62), P=.021, respectively. Conclusions: Three-Tesla multiparametric erMRI in men with favorable-risk PC provides information beyond that contained in known preoperative predictors about the presence of occult extraprostatic and/or high-grade PC. If validated in additional studies, this information can be used to counsel men planning to undergo radical prostatectomy or radiation therapy about the possible need for adjuvant radiation therapy or the utility of adding hormone therapy, respectively.« less

To quantify the successful outcome in patients following optic nerve decompression in post traumatic unilateral optic neuropathy in form of improvement in visual acuity. A prospective study was carried out over a period of 5 years (January 2011 to June 2016) at civil hospital Ahmedabad. Total 20 patients were selected with optic neuropathy including patients with direct and indirect trauma to unilateral optic nerve, not responding to conservative management, leading to optic neuropathy and subsequent impairment in vision and blindness. Decompression was done via Transnasal-Ethmo-sphenoidal route and outcome was assessed in form of post-operative visual acuity improvement at 1 month, 6 months and 1 year follow up. After surgical decompression complete recovery of visual acuity was achieved in 16 (80%) patients and partial recovery in 4 (20%). Endoscopic transnasal approach is beneficial in traumatic optic neuropathy not responding to steroid therapy and can prevent permanent disability if earlier intervention is done prior to irreversible damage to the nerve. Endoscopic optic nerve surgery can decompress the traumatic and oedematous optic nerve with proper exposure of orbital apex and optic canal without any major intracranial, intraorbital and transnasal complications.

The da Vinci Xi robot has been introduced as the successor to the Si platform. The promise of the Xi is to open the door to new surgical procedures. For robotic-assisted radical prostatectomy (RARP)/pelvic surgery, the potential is better vision and longer instruments. How has the Xi impacted on operative and pathological parameters as indicators of surgical performance? This is a comparison of an initial series of 42 RARPs with the Xi system in 2015 with a series using the Si system immediately before Xi uptake in the same calendar year, and an Si series by the same surgeon synchronously as the Xi series using operative time, blood loss, and positive margins as surrogates of surgical performance. Subjectively and objectively, there is a learning curve to Xi uptake in longer operative times but no impact on T2 positive margins which are the most reflective single measure of RARP outcomes. Subjectively, the vision of the Xi is inferior to the Si system, and the integrated diathermy system and automated setup are quirky. All require experience to overcome. There is a learning curve to progress from the Si to Xi da Vinci surgical platforms, but this does not negatively impact the outcome.
