    Klinefelter syndrome is the most common sex chromosome abnormality (SCA) in infertile patients and 47,XXY genomic configuration constitutes most of the cases. However, additional Xs and/or Y such as 48,XXYY, 48,XXXY, and 47,XYY can occur less frequently than 47,XXY. Those configurations were considered as variants of Klinefelter syndrome. In this report, we present an infertile man with tall stature and decreased testicular volume. Semen analysis and hormonal evaluation supported the diagnosis of nonobstructive azoospermia. Genetic investigation demonstrated an abnormal male karyotype with two X chromosomes and two Y chromosomes consistent with 48,XXYY(17)/47,XYY (13). Additionally, the patient expressed cognitive and affective problems which were documented by psychomotor retardation and borderline intelligence measured by an IQ value between 70 and 80. Systemic evaluation also revealed cross ectopy and malrotation of the right kidney in the patient. The couple was referred to microtesticular sperm extraction (micro-TESE)/intracytoplasmic sperm injection (ICSI) cycles and preimplantation genetic diagnosis (PGD). To the best of our knowledge, this is the first report of combination of XYY and XXYY syndromes associated with cognitive, affective dysfunction and renal malrotation. PMID:26075116

    Renal oncocytoma is an uncommon benign neoplasm of tubular epithelial origin. It usually occurs as single mass and clinically may be confused with renal cell carcinoma. Angiographic, CT and ultrasound studies may suggest the diagnosis but they are not pathognomonic. The clinical, diagnostic and anatomopathological features of two cases are presented and discussed.

    Renal infarction (RI) is a rarely seen disorder, and the diagnosis is often missed. The two major causes of RI are thromboemboli originhating from a thrombus in the heart or aorta, and in-situ thrombosis of a renal artery. We report a case of RI that developed due to renal artery and vein thrombosis, as confirmed by pathological evaluation of the nephrectomy material, three weeks after renal cyst aspiration.

    As the number of renal surgical interventions increase a better understanding of the anatomy of renal arteries and their branches gain in importance. Here we describe a common trunk from the right side of the aorta ramifying into suprarenal and two renal hilar arteries in a 40-year-old male cadaver detected during dissections performed in a routine gross anatomy course. The suprarenal branch is divided into several smaller branches to supply blood to the suprarenal gland. The superior renal hilar artery gave rise to the right testicular artery and an additional suprarenal artery. The inferior renal hilar artery gave rise to one more additional suprarenal artery. The superior renal hilar artery crossed the inferior renal hilar artery. On the same side renal veins were also doubled. For better outcome interesting variations such as in this case should be kept in mind before and during any interventions involving this region.

    Renal leiomyomas are rare benign tumours of the kidney originating from muscle cells. They are usually found by an autopsy, whether the patient is asymptomatic or has symptoms (i.e., abdominal/flank pain, hematuria, palpable mass). Today the widespread use of ultrasonography and computed tomography has increased the detection of clinically asymptomatic renal leiomyomas. The differential diagnosis between leiomyomas and other malignant lesions (above all renal cell carcinoma or leiomyosarcoma) is still possible by histological examination. Radiological examinations are not sufficient for the differential diagnosis. Renal leiomyomas have no aggressive behaviour and they usually do not metastasize. The prognosis, after surgery, is excellent without recurrence. We report a case of leiomyoma in a 31-year-old man who presented hematuria and flank pain. We also review the literature and provide a summary of clinical, radiological and histological features of renal leiomyomas. PMID:22511443

    Malacoplakia is a chronic inflammatory disease which specificity is pathological: Von Hansemann's cells and Michaelis-Gutmann's bodies. Renal localization is very rare. Two cases have been collected, the diagnosis having been done in the two cases on a nephrectomy specimen. Because there is no specific symptomatology to renal malacoplakia, the presence of a particular context should suggest the diagnosis and lead to renal needle biopsy. Thus nephrectomy could be avoided. The primum movins of the affection is a trouble of the phagocytosis. The place of surgery in the treatment of renal malacoplakia remains uncertain due to the lack of experience with the medical treatment. The latter is based on the prescription of cholinergic drugs, and has proved some efficacy in other localizations, as bladder. PMID:8163848

    2015-01-01

    Longstanding renal calculus is a risk factor of squamous cell carcinoma (SCC) of the renal pelvis. It is highly aggressive and usually diagnosed at advanced stages with a poor prognosis. We present two cases of kidney stone complications with renal pelvic SCC. These two patients had a radical nephrectomy and the dissected tissues were renal pelvic SCC. Our cases further emphasize that renal pelvic SCC should be considered in patients with longstanding renal calculus. These cases contribute greatly to an early diagnosis and early treatment, both of which will significantly minimize the damage of, and markedly improve the prognosis of, renal pelvic SCC.

  9. Ventricular ectopy and QTc-interval prolongation associated with dronedarone therapy.

    PubMed

    2013-10-01

    Amiodarone is an effective treatment for atrial and ventricular arrhythmias, but its use is limited by a toxic adverse-effect profile. Although dronedarone has been touted as an antiarrhythmic agent devoid of both solid organ toxicity and proarrhythmic properties, its potential for prolonging ventricular repolarization may augment triggered ectopy. We describe a 66-year-old man who began dronedarone 400 mg twice/day for new-onset paroxysmal atrial fibrillation; he had no left ventricular dysfunction or clinical heart failure. Three months after starting the drug, he complained of malaise, fatigue, and rare palpitations. Twenty four-hour Holter monitoring revealed increased premature ventricular complexes, and the rate-corrected QT (QTc) interval was prolonged (range 525-760 msec). Dronedarone was discontinued and the patient's symptoms gradually resolved over the next 3 weeks. Holter monitoring revealed a marked reduction in ventricular ectopy burden, and the QTc interval decreased to his baseline values. Even in the absence of documented symptomatic torsade de pointes, this case suggests that caution should be exercised when prescribing dronedarone and that serial QTc interval monitoring may be appropriate. In addition, clinicians should have a low threshold to perform Holter monitoring if symptoms develop during dronedarone therapy.

    2015-01-01

    Urothelial carcinoma (UC) originated from renal pelvis is the common tumor of the urinary system, however, neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in the complete renal and ureteral duplex cases. We present the first case of renal pelvis UC of the upper moiety in a complete right renal duplex. This male patient has bilateral complete renal and ureteral duplex. To the best of our knowledge, this is the first reported case of renal pelvis UC in a complete renal duplex system. After this experience we feel that the diagnosis of renal pelvis UC in duplex kidneys is not so easy, and once the diagnosis is determined, the whole renal duplex units and bladder cuff or ectopic orifice should be excised radically.

    Renal infection with flagellated protozoa was retrospectively evaluated in 29 reptiles, including 12 turtles, 7 tortoises, and 6 chameleons; overall, 20 species of reptiles were represented. Most cases presented with nonspecific clinical signs or a combination of several concurrent diseases. Nineteen of 29 reptiles had tubulointerstitial nephritis associated with flagellates, and this lesion was considered contributory to death in 15 cases, although concurrent diseases were frequent. Infection was invasive into the renal interstitium in three reptiles due to tubular rupture and in one chameleon also spread to adjacent tissues, coelomic cavity, and blood vessels due to renal rupture. Cytologic or ultrastructural evaluation of trophozoites in two cases was consistent with diplomonad flagellates. Renal disease was often complicated with soft-tissue mineralization and/or gout. Gastrointestinal and cloacal infection with flagellates and inflammation were frequent in reptiles in which the digestive tract was available for histopathologic examination, and this supports the possibility of infections ascending the urinary tract from the cloaca. Renal disease associated with flagellate protozoa is rare in vertebrates but appears to be relevant in reptiles, particularly chelonians and chameleons.

    We report 13 cases of renal oncocytoma. Urinary symptoms occurred in only 3 cases. The patient's age ranged from 41 to 74 years with an average of 62.3 years. The mean tumor diameter was 5.6 cm (range: 1.5-14). Diagnostic features of ultrasonography, CT scan and, in some instances, angiography were suggestive of renal oncocytoma in 2 patients, but never affirmative, 4 patients were treated by partial nephrectomy. No local or metastatic recurrence was observed with a mean follow-up of 30.8 months, ranging from 6 to 96 months. We assume that the term renal oncocytoma should be restricted to tumors exclusively composed of regular oncocytic cells with an eosinophilic granular mitochondria-rich cytoplasm and an absence of malignant potential. Diagnostic imaging characteristics may sometimes suggest the diagnosis of renal oncocytoma, but cannot eliminate the main differential diagnosis, i.e. granular renal cell adenocarcinoma. When the tumor is small and unifocal, nephron sparing surgery may be considered. Whether or not the diagnosis has been confirmed by fine needle aspiration, conservative surgery must be controlled by intraoperative frozen sections of the tumor and surgical margins.

    A 75-year-old woman was referred to our department for evaluation of a left renal tumor. Computed tomography and other imaging studies demonstrated a left renal mass and tumor extension into the left renal vein passing caudally behind the aorta. We clinically diagnosed the tumor as renal cell carcinoma (RCC) associated with a retroaortic left renal vein thrombus, and performed a radical nephrectomy. Pathological examination of the surgical specimen showed a grade 2, clear cell carcinoma with a renal vein thrombus and negative surgical margin. Retroaortic left renal vein is a rare anomaly with a prevalence of 1.8-2.4%. RCC associated with a retroaortic left renal vein thrombus is rarer still. To our knowledge, this is only the third case report to describe an RCC associated with a tumor thrombus in the retroaortic left renal vein.

    Hemangioperycytoma is a rare perivascular tumor that seldom involves the urogenital system. This tumor often appears with an unspecific clinical picture, and sometimes is associated with hematuria or hypertension. Diagnosis is based on a combination of histological and immunohistological findings. We report a case of a 52-year-old patient with renal hemangiopericytoma who underwent surgical treatment at our service. This report also includes a literature review on the subject. PMID:25946050

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normal however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure.

    A 58-year-old woman visited our hospital with nausea and right flank pain. At first abdominal ultrasonography was performed, suggesting a right renal infarction. Computed tomography (CT) study of the abdomen with intravenous contrast was performed to determine the cause of the symptoms. The scan revealed poor enhancement in the lower half of the right kidney. She was diagnosed with a right renal infarction. She was initially treated with anticoagulant therapy, but 5 days later, she complained of nausea. This time, CT demonstrated exacerbation of a right renal infarction with renal artery dissection. Based on this finding, we performed a right nephrectomy. The result of pathology was segmental arterial mediolysis. She was discharged 12 days after the surgery and is doing well at 6 months after discharge. Spontaneous renal artery dissection is a rare disease. It constitutes approximately 0.05% of arteriographic dissections. In addition, spontaneous renal artery dissection shows nonspecific symptoms. Together, these two factors may cause a delay in diagnosis.

    Background Although psychological stress has been implicated in the pathogenesis of ventricular arrhythmias, the relationship between self-reported stress and ventricular ectopy has not been evaluated under naturalistic conditions in acute post-MI patients, a group at elevated risk for arrhythmias. Methods Diary-reported stress was measured during 24-hour Holter monitoring in 80 patients (52 men, 28 women) approximately 12 weeks following MI. In addition, state and trait anxiety were measured using the Spielberger State and Trait anxiety inventory (STAI), administered at the beginning of the 24-hour holter monitoring session. The relationship between diary reported stress, anxiety, and ventricular ectopy was evaluated. Results Mean diary-reported stress (β= .29, p = .01) was associated with total ventricular ectopy. State anxiety was also associated with 24-hour ectopy (β= .24, p = .04); however, trait anxiety was not significantly associated with ectopy. Temporal analyses of the relationship between stress and ectopy showed that diary-reported stress was associated with an increase in the number of VPBs occurring in the following hour (B = 0.74, p < .0001). Conclusions These findings extend existing evidence linking psychological factors to ventricular arrhythmias by demonstrating that psychological stress predicts increased arrhythmic activity during routine daily activities in post-MI patients.

    2015-01-01

    Renal endometriosis is a rare disease for which the mechanisms of pathogenesis are still unclear. As such, early diagnosis and an appropriate treatment are often delayed because of the tendency to be misdiagnosed as a renal tumor. In October 2013 we performed a radical nephrectomy for a 37-year-old woman with renal endometriosis who was preoperatively misdiagnosed as having a right renal tumor. Avoiding the misdiagnosis of renal endometriosis requires a detailed case history, especially regarding whether the cyclicity of lumbodorsal pain and hematuria correlates with patients' menstrual cycles. Imaging examinations are commonly helpful for localization, whereas relieving symptoms with drugs to create a hypoestrogenic state is useful for clinical diagnosis. However, a final diagnosis for renal endometriosis still must depend on histopathologic examination. PMID:25692445

    Primary renal lymphoma (PRL) is a rare entity with a history of controversy regarding its existence. Lymphomatous involvement of the kidney is more commonly seen secondarily to spread from an adjacent lymphomatous mass, rather than arising primarily from the kidney. PRL can mimic other renal lesions such as renal cell carcinoma, renal abscess, and metastasis; therefore, an early diagnosis is crucial to guide treatment and properly assess prognosis. We present a rare case of a 77 year-old male who presented with hematuria and PRL mimicking a subcapsular hematoma. PMID:24421949

A fifth central tumor corresponded to a conventional clear cell renal cell carcinoma. Biphasic squamoid alveolar renal cell carcinoma is a rare tumor that has been very recently characterized as a distinct histotype within the spectrum of papillary renal cell carcinoma. Immunostaining with cyclin D1 seems to be specific of this tumor subtype. This is the first reported case with multifocal presentation. PMID:27158455

Renal hemorrhage and neoplastic transformation of the cyst epithelium are the two major complications of acquired renal cystic disease, and were present in this patient. The full clinical significance of the acquired renal cystic lesion is still unclear, although the possibility of renal tumors and massive renal and retroperitoneal hemorrhage should be considered in the long-term dialysis population.

    A 49-year-old lady presented with multiple recurring painful lesions over her thighs, arms, and back. Past medical history included a left sided nephrectomy for renal cell carcinoma and a hysterectomy for multiple uterine fibroids (leiomyomas). Histopathological examination revealed changes consistent with pilar leiomyomas. Gene mutation analysis confirmed a diagnosis of hereditary leiomyomatosis and renal cell carcinoma. Hereditary leiomyomatosis and renal cell carcinoma is an uncommon autosomal dominant condition characterised by the concurrent presentation of cutaneous and uterine leiomyomas. Renal cell carcinoma associated with this condition is more aggressive and a significant cause of mortality. Due to this association with potentially fatal renal cell carcinoma we felt that it was important to highlight this case with an update on pathophysiology and management. PMID:27144040

    The incidence of urogenital tuberculosis is still frequent and constitutes a current public health problem in Morocco, a country in which tuberculosis is endemic. The clinical presentation of this form of the disease may be misleading. The pseudotumoral type of renal tuberculosis is extremely uncommon, and in this study this disease has been described in a young patient. The radiological findings suggested the possibility of this lesion being renal cancer. The preliminary diagnosis was corrected and a definitive diagnosis of pseudotumor was made following pathological examination of the surgically-removed kidney.

    Environmental exposure to inhaled carbon monoxide (CO) increases coronary artery disease risk. Sudden cardiac death, a frequent manifestation of coronary artery disease, is usually a result of ventricular dysrhythmia. The effect of exposure to CO at sea level (CO/SL) and simulated high (2.1 km) altitudes (CO/HA) on the incidence of cardiac ectopy in subjects with coronary artery disease was investigated. A double-blind crossover study was conducted, with random-order assignment, and each subject served as his own control. Seventeen men with documented coronary artery disease and stable angina pectoris performed cardiopulmonary exercise stress tests after random exposure to either CO or clean air (CA) at sea level (CA/SL) or at a simulated 2.1-km high altitude (CA/HA). The individual CO and HA exposure conditions were each selected to reduce the percentage of oxygen saturation of the subjects arterial blood by 4%. Subjects blood carboxyhemoglobin levels were increased form an average of 0.62% after clean-air exposure to 3.91% of saturation after CO exposure. The percentage of oxygen saturation in arterial blood was reduced from a baseline level of 98% to approximately 94% after CO/SL or CA/HA and to approximately 90% after CO/HA. Compared with the CA/SL the average incidence of exercise-induced ventricular ectopy was approximately doubled after all exposures and a significant trend (p {le} .05) of increased ectopy with decreased oxygen saturation in arterial blood was observed. Yet, among subjects who were free from ectopy (n=11) on CA/SL, only 2 subjects developed ectopy after CO/HA. No episodes of ventricular tachycardia or fibrillation occurred. The findings indicated that exposure to increased levels of hypoxemia, resulting from hypoxic and/or CO exposures, increased the susceptibility to ventricular ectopy during exercise in individuals with stable angina pectoris; however, this risk was nominal for those without ectopy. 26 refs., 1 fig., 2 tabs.

    A 32-year-old man was referred to our hospital for treatment of left renal cystic tumor, which was detected by computed tomographic (CT) scan 3 years ago. CT scan showed a multilocular cyst (5 cm in diameter) with a solid tumor in the left kidney which was enhanced with contrast. There was no evidence of extrarenal invasion or distant metastasis. We performed retroperitoneal laparoscopic radical nephrectomy. Pathological examinations revealed a cellular arrangement specific to carcinoid tumor and positive for CD56 (NCAM) and neuron-specific enolase. The cell proliferation rate was estimated to be under 2% with Ki67 staining. The pathological diagnosis was renal neuroendocrine tumor (carcinoid). At the 9-month follow up, he had no evidence of local recurrence or metastasis.

    Renal stone disease is characterized by the differences depending on the age, gender, and the geographic location of the patients. Seventy-five percent of the renal stone components is the calcium (Ca). The most common type of the stones is the Ca oxalate stones, while Ca phosphate, uric acid, struvite, and sistine stones are more rarely reported. Other than these types, triamterene, adenosine, silica, indinavir, and ephedrine stones are also reported in the literature as case reports. However, to the best of our knowledge, aluminum hydroxide stones was not reported reported before. Herein we will report a 38-years-old woman with the history of recurrent renal colic disease whose renal stone was determined as aluminum hydroxide stone in type. Aluminum mineral may be considered in the formation of kidney stones as it is widely used in the field of healthcare and cosmetics. PMID:25013740

    Vaishya, Raju; Nyokabi, David Ndegwa; Vaish, Abhishek

    2014-01-01

    Chronic renal disease is often associated with secondary hyperparathyroidism (HPP) and rarely with tertiary HPP. Hip arthritis with protrusio acetabuli, secondary to tertiary HPP, is a rare case scenario and has not been described well in the literature. We present a rare case of bilateral hip arthritis with protrusio acetabuli secondary to renal osteodystrophy due to tertiary HPP. The diagnosis and aetiology of hip arthritis and its treatment have been discussed along with a detailed review of literature of skeletal lesions due to HPP. PMID:24554674

    The agenesis of the Müllerian duct is the second most common cause of primary amenorrhoea after Turner syndrome. The abnormal development of Müllerian duct often associates with the urinary tract and skeletal abnormalities. MURCS (Müllerian duct aplasia-renal agenesis-cervicothoracic somite dysplasia) association is a unique and rare developmental disorder with four common features of uterine hypoplasia or aplasia, renal agenesis or ectopy, vertebral anomalies and short stature. We report a case of young female with primary amenorrhoea. She had well-developed secondary sexual characteristics along with multiple congenital developmental abnormalities such as the absence of uterus, ectopic kidney, cervical vertebral fusion, hemivertebrae, scoliosis, cervical rib, facial asymmetry and growth retardation. Our case highlights the rarity and clinical importance of this syndrome. For the evaluation of primary amenorrhoea in a female with well-developed secondary sexual characteristics, congenital anomalies should be ruled out before hormone and karyotype analyses.

    Background. We report the case of a male infant whose right kidney migrated to an ectopic position after birth. The migration of a kidney in postnatal life without any symptoms has not been reported in literature so far. Case Presentation. In a series of antenatal and the first postnatal ultrasound scans, the right kidney was normally located within the right renal fossa. During the first 3 months of life, the kidney migrated to a subdiaphragmatic position. This was confirmed on MRI scan. The infant was asymptomatic with normal renal function and blood pressure. Conclusion. Postnatal migration of a kidney has been described in cases of diaphragmatic hernia or nephroptosis. In this report, we describe a case of kidney migration where there were no underlying anatomical defects to provide an explanation for the kidney migration. This is the first report in literature of a case of postnatal migration of a kidney. PMID:27668105

    This descriptive report describes the case of a 50 year-old woman with bipolar disorder, whose maintenance therapy comprised risperidone, sodium valproato and lithium carbonate without any past occurrence of toxicity. Her past medical history was significant for hypertension, cardiopathy and obesity. She presented with a 1-week history of fever, increasing confusion and slurred speech. At presentation, the patient was somnolent. Laboratory investigations revealed a serum creatinine of 3,6 mg/dl, BUN 45 mg/dl serum lithium 3,0 mEq/L with polyuria defined as more than 3 litres a day. EEG and ECG were abnormal. CT brain scanning and lumbar puncture were negative for brain haemorrage or infection. Lithium toxicity causes impairment of renal concentration and encephalopathy due to lithium recirculation, a mechanism responsible for the so-called cerebro-renal syndrome, where dialysis plays an important role in treatment.The patient was treated with continous veno-venous haemodiafiltration (CVVHDF) over 35 hours with gradual improvement of her general condition and efficacy of renal concentration. Our case highlights a few important points. Lithium nefrotoxicity and neurotoxicity can cause a cerebro-renal syndrome even when serum lithium levels are not particularly raised (2,5-3,5 mEq/L). Haemodialysis is the treatment of choice to reduce the molecular mechanisms of lithium-related changes in urinary concentration and reinstate dopaminergic activity in the brain.

    Primary malignant tumors of the renal pelvis are relatively rare. Urothelial carcinoma of renal pelvis accounts for 7% of all renal neoplasms, with Squamous Cell Carcinoma (SCC) forming a very small percentage of these cases. Urothelial and SCC of renal pelvis is still a rarer entity. This malignancy of the renal pelvis lacks the characteristic presentation of common renal cell carcinoma and usually presents at an advanced disease stage. We report a case of urothelial and SCC of renal pelvis in a 61-year-old male who presented with non-specific clinical complaints like dysuria and right flank pain. PMID:27790450

    Intrathoracic kidney is a rare congenital abnormality with lowest frequency among all renal ectopias. Patients with thoracic kidneys are usually asymptomatic, and the condition is usually discovered incidentally during radiological evaluation for other conditions or during thoracic surgery. We report a case of a 62-year-old male who was referred to our department for renal scintigraphy for a nonvisualized left kidney on ultrasonography report. Both Tc-99m dimercaptosuccinic acid and diethylenetriaminepentaacetic acid scans revealed a left thoracic kidney which was confirmed by CT scan of the thorax and abdomen. PMID:27385896

    Diagnosis of synchronous primary genitourinary tumors are uncommon. Thus far, about 50 cases of synchronous renal tumors have been reported in the literature. We present for the first time a case of a 83-year-old man presenting in the same kidney two separate primary malignancies, a TCC of the renal pelvis and a papillary renal cell carcinoma Type 1. Considered the increased incidence of genitourinary tumors, in presence of a small renal tumor with hematuria, in our opinion, is necessary to pay attention to the diagnostic phase for the chance to highlight an urothelial cancer.

    Acute antibody mediated rejection (AMR) is one of the most important complications after kidney transplantation. Renal graft biopsy is safe and reliable without adverse effects on the patients and transplanted kidneys, which was of great instructive significance in diagnosis and treatment of renal allograft dysfunction after renal transplantation. This paper reported a case series of 106 patients underwent renal allograft biopsies. All biopsies were evaluated according to the Banff 2007 schema. 52 examples were obtained within 1 month after transplantation, and there were another 20 examples in one to two months and other 34 examples in two to three months. Appropriate therapy was applied and clinical outcomes were observed. All patients received renal biopsies and anti-inflammatory and hemostasis treatment without complications. There were 2 cases of hyperacute rejection, and 15 cases of acute AMR. All Paraffin-embedded samples were stained by HE, periodic acid-Schiff (PAS), Masson, and immunohistochemistry (C4d, cd20, cd45RO, SV40). All samples were found C4d immunohistochemical staining positive. Patients with acute AMR were managed by steroid intravenous pulse therapy, Rabbit anti-thymocyte globulin intravenous pulse therapy, anti CD20 monoclonal antibody intravenous therapy and so on. Two cases of hyperacute rejection had renal failure, and received kidney excision; 12 cases in 15 cases of AMR recovered, another 2 cases did not recover with high-level creatine, and other 2 cases of renal allograft received excision.

    Renal leiomyomas are exceptionally rare benign tumours of the kidney. Although the renal leiomyomas usually do not metastasize, the differential diagnosis between renal leiomyomas and malign lesions (leiomyosarcoma or renal cell carcinoma) cannot be done by radiological examinations, but is possible by histological examination. Surgery is the preferred treatment. After surgery, the prognosis is excellent without recurrence. Although uterine leiomyomas can be multicentric, renal leiomyomas have been single lesions. We report an incidentally detected case of bilateral renal leiomyoma in a 50-year-old woman with a 5-year follow-up. We also review the literature and discuss clinical, radiological and histological features of renal leiomyomas. PMID:26664510

    Renal cell carcinoma accounts for 3% of all adult malignant tumors. Common sites of metastases are lungs, bone, liver, brain and adrenal glands. Metastatic disease to the head and neck ranges from 15% to 30%. The 5-year survival rate after nephrectomy is 60%-75%, but with multiorgan metastases the 5-year survival rate is significantly lower, 0-7%. A case is presented of a female patient diagnosed with renal cell carcinoma metastases to the paranasal sinuses, diagnosed and treated at the Department of ENT and Head and Neck Surgery, Zadar General Hospital, Zadar, Croatia. The tumor was surgically removed. Unfortunately, the patient died one year after the procedure due to multiorgan failure. Although metastases of renal cell carcinoma to the head and neck are very rare, it should be first suspected when investigating a metastatic tumor in this region. Surgical excision offers the best hope for long term survival. In case of unresectable tumor, other treatment options should be considered such as radiotherapy, immunotherapy and chemotherapy.

    Renal cell carcinoma is the most common form of malignant renal tumour and is extremely lethal. About 25% of the patients develop metastasis at the time of diagnosis, and in many cases during the course of the disease, affecting the lung, lymphatic ganglions, liver, and bone, with skin metastases being quite rare. A 73-year-old patient, who had undergone surgery for adenocarcinoma in the left kidney 10 years previously, visited the dermatological service due to the appearance of recent, rapidly-developing lesion at the back of his neck. It was decided to remove it surgically. The histological study confirmed clear cell carcinoma that was probably of renal origin. A computed tomography scan was performed on the thorax and abdomen, and lesions were observed that were compatible with metastasis in the right kidney and left lung. Treatment with a multikinase angiogenesis inhibitor (sunitib) was started. Due to the late development of the skin metastases and those in other regions that worsen the prognosis, these patients must be subjected to long-term clinical observation. Urologist should pay attention to cutaneous lesion appearing in these patients as in many times they look like benign lesion. PMID:19918439

A 42-year-old woman who was diagnosed as tuberous sclerosis at the age of 18 complained of left flank pain and abdominal fullness. Bilateral renal AMLs were pointed out when complete examinations were performed for hypertension at the age of 32. She suffered from severe left flank pain and abdominal distension due to the left renal tumor. Left nephrectomy and excision of the renal hilar tumor were performed. The left renal tumor weighed 1120 g, the perirenal space was filled with the tumor. histopathological diagnosis of the left renal tumor and renal hilar tumor was AML. In our case, bilateral pneumothorax appeared, and chest CT scan revealed bilateral multiple pulmonary cysts. Histopathological diagnosis of pulmonary cysts was LAM. Other complications of our case are intracranial calcification and adenoma sebaceum.

    ABSTRACT Associated congenital anomalies are seen in 21% of retrocaval ureter patients; among them, associated contralateral renal agenesis is a very rare entity. We report one such case of right circumcaval ureter with left renal agenesis, diagnosed after febrile UTI. Surgical correction with uretero-ureterostomy was successful. In literature very few such cases are reported and only one case with renal failure was reported. Unilateral renal agenesis cases complicated by associated such anomalies need definitive management and lifelong clinical monitoring to diagnose and prevent chronic kidney disease. PMID:27564299

    Pulmonary renal syndrome is a class of small vessel vasculitides that are characterized by the dual presentation of diffuse alveolar hemorrhage (DAH) and glomerulonephritis. Pulmonary renal syndrome has multiple etiologies, but its development has been rarely reported following infection with group A streptococcus. We present the case of a 36-year-old Native American male who was transferred to our facility due to refractory hypoxic respiratory failure. He had been diagnosed with streptococcal pharyngitis 2 weeks prior to admission. Given the presence of hemoptysis, bronchoscopy was performed and was consistent with DAH. Urinalysis demonstrated hematuria and proteinuria, in the setting of elevated creatinine and blood urea nitrogen. Additionally, antistreptolysin O titer was positive. Given the constellation of laboratory findings and history of streptococcal pharyngitis, the patient was diagnosed with PRS secondary to streptococcal infection. High-dose methylprednisolone was initiated with concomitant plasmapheresis. He was extubated successfully after his respiratory status improved and was eventually discharged home after making a full recovery within 2 weeks after admission. This case illustrates the importance of clinically relevant sequelae of streptococcal infection as well as the appropriate treatment of PRS secondary to streptococcal pharyngitis with plasmapheresis and intravenous corticosteroids.

    Associations between Depo-Provera (injectable, progesterone-only contraceptive) use and visible disruption of cervical epithelium and cervical ectopy were investigated using data collected as part of a cervical cancer screening study in periurban Cape Town, South Africa. Women were interviewed about their contraceptive use, and underwent a gynecologic examination that included two 35-mm photographs of the cervix after application of 5% acetic acid. Photographs of 723 subjects were reviewed (blind to clinical information and using systematic criteria developed before review) for evidence of atrophy and epithelial disruption, including inflammation and ulceration. The percentage of the cervix covered with columnar epithelium (ectopy) was also estimated from the photographs. A random sample of 85 photographs was reviewed again for reliability. A total of 121 current users of Depo-Provera were no more likely to have evidence of epithelial disruption (38%) than 574 nonusers (39%), odds ratio (OR) = 1.37, 95% CI: 0.89-2.11 adjusting for age and parity. The prevalence of significant ectopy (columnar epithelium covering > 10% of the cervix) was also no different among current Depo-Provera users (OR = 1.22, 95% CI: 0.80-1.86 adjusting for age and parity). Reliability of visual scoring of epithelial disruption and ectopy was excellent (kappa = 0.8). Although the underlying prevalence of visible disruption of cervical epithelium was very high, current use of Depo-Provera was not associated with increased prevalence of visible disruption of the cervical epithelium or with ectopy in this sample of African women.

    There is great debate as to whether the benefit gained from the knowledge of renal histology outweighs the risk to the patient from the biopsy procedure. We conducted a prospective study of 276 native renal biopsies performed on 266 patients from a single centre in 1991 to assess the effect of the knowledge of renal histology on patient management. Biopsies were performed under ultrasound guidance using the Trucut biopsy needle. The indications for biopsy were: non-nephrotic proteinuria alone (25), haematuria and proteinuria (28), nephrotic range proteinuria (28), acute renal failure (31), haematuria alone (36), and chronic renal failure (128). Two hundred and sixty-three biopsies were successful. The mean number of glomeruli obtained was 23, range 0-115. Eight patients developed macroscopic haematuria of which two required blood transfusion. The result of the biopsy altered management in 24/28 (86%) of cases of nephrotic range proteinuria, 22/31 (71%) of cases of acute renal failure, 58/128 (45%) of cases of chronic renal failure, 9/28 (32%) of cases with haematuria and proteinuria, 3/25 (12%) of cases with non-nephrotic proteinuria alone, and 1/36 (3%) of cases with haematuria alone. management was altered in 42% of cases overall. These data suggest that knowledge of renal histology is essential in the management of patients with renal disease.

    Allograft renal vein thrombosis (RVT) is an uncommon but potentially catastrophic complication. Although it usually occurs in the early posttransplant period and is associated with surgical complications or vascular rejection, it may develop later, when it is generally related with a hypercoagulable state. Typical clinical presentation is sudden oligoanuric acute renal failure, and hematuria, with a painful and swollen renal allograft. Confirmation of the diagnosis requires Doppler ultrasound and computed tomography. Herein we have reported a successfully treated case of late RVT that developed in an allograft with recurrent membranous nephropathy associated with the nephrotic syndrome. The patient fully recovered renal graft function a few days after presentation, which was related to anticoagulant therapy. We demonstrated complete recanalization of the venous thrombosis.

    A 49-year-old female patient presented with a massive left renal tumor, recurrent left flank pain and gross hematuria. The tumor was accompanied by a renal vein tumor thrombus, pancreatic infiltration and a solitary adrenal metastasis. Radical nephrectomy, distal pancreatectomy, ipsilateral adrenalectomy and splenectomy were performed. Histopathological examination suggested high-grade urothelial carcinoma (UC); however, tumor recurrence and multiple metastases were detected only 3 months after the surgery, and the patient succumbed during follow-up 1 month later. To the best of our knowledge, this is the first case of renal UC of such advanced stage with renal vein tumor thrombus, pancreatic infiltration and a solitary adrenal metastasis. PMID:27446406

    2016-01-01

    Study Objectives: To determine whether sleep disruption increases ventricular ectopy and the risk of cardiac arrest in hospitalized patients. Methods: Hospital emergency codes (HEC) trigger multiple hospital-wide overhead announcements. In 2014 an electronic “code white” program was instituted to protect staff from violent patients. This resulted in an increase in nocturnal HEC. Telemetry data was examined between September 14 and October 2, 2014. The frequency of nocturnal announcements was correlated with changes in frequency of premature ventricular complexes per hour (PVC/h). Cardiac arrest data were examined over a 3-y period. All HEC were assumed to have triggered announcements. The relationship between nocturnal HEC and the incidence of subsequent cardiac arrest was examined. Results: 2,603 hours of telemetry were analyzed in 87 patients. During nights with two or fewer announcements, PVC/h decreased 33% and remained 30% lower the next day. On nights with four or more announcements, PVC/h increased 23% (P < 0.001) and further increased 85% the next day (P = 0.001). In 2014, following the introduction of the code white program, the frequency of all HEC increased from 1.1/day to 6.2/day (P < 0.05). The frequency of cardiac arrest/24 h rose from 0.46/day in 2012–2013 to 0.62/day in 2014 (P = 0.001). During daytime hours (06:00–22:00), from 2012 through 2014, the frequency of cardiac arrest following zero, one or at least two nocturnal HEC were 0.331 ± 0.03, 0.396 ± 0.04 and 0.471 ± 0.09 respectively (R2 = 0.99, P = 0.03). Conclusions: Sleep disruption is associated with increased ventricular ectopy and increased frequency of cardiac arrest. Citation: Miner SE, Pahal D, Nichols L, Darwood A, Nield LE, Wulffart Z.

    Acute renal infarction is a well known, although relatively unfrequent, cause of flank pain resistant to administration of spasmolytic and nonsteroidal anti-inflammatory drugs. We present an original case of a 41-year-old man, complaining of acute severe left flank pain, resistant to common analgesic therapy, who was diagnosed of segmental renal infarction of a branch of left renal artery. Pathophysiology of renal damage in cocaine users is multifactorial, and it has been postulated that the right kidney was more prone to ischaemia. Left kidney represents an extremely unusual site of cocaine-related renal infarction.

    A case of renal hypertension after pyelolithotomy cured by segmental nephrectomy is reported. The patient, a 39-year-old man had had pyelolithotomy performed by the lumbodorsal approach at another hospital. Two months after operation he started to complain of headache and palpitation. The blood pressure was markedly high when he visited our hospital and peripheral plasma renin activity was also elevated. Urinalysis was normal except for slight proteinuria. The excretory urogram demonstrated cortical scarring in the lower portion of the left kidney. The renal scintigram demonstrated low uptake in this area, suggesting renal infarction. Renal arteriogram showed decreased vascularity in this area. Plasma renin activity was measured on the blood drawn from the renal vein of both sides and the ratio was about 2.4, and renin activity of the segmental renal vein from the left lower portion was elevated. Segmental nephrectomy of the lower pole was performed. The blood pressure three weeks after lower pole resection was estimated to be normal and renin activity returned to an almost normal level. Discussion was made on the cause of renal hypertension after renal surgery. In this case, it was suggested that renal hypertension is caused by subinfraction due to lesions of the dorsal renal artery in surgery for renal calculus. PMID:3832924

    Tuberous sclerosis complex (TSC) is an autosomal dominant hereditary disease characterized by a high rate of spontaneous mutations involving at least two loci: TSC(1) (9q34) and TSC(2) (16p13). It results in hamartomas or tumours which can affect a variety of organs, most commonly the brain, skin and kidneys. At least half of patients with TSC have underlying renal pathology, most commonly angiomyolipomas (AML) and/or cysts with, more rarely, adenocarcinoma, but oncocytomas, sarcomas, interstitial fibrosis and glomerulosclerosis have all been reported. Renal disorders may be asymptomatic or associated with acute lumbar ache, hematuria, abdominal mass, retroperitoneal hemorrhage. Renal failure is infrequent. The diagnosis of this disease is often performed, as in the present cases, very late and it is made possible by radiological examinations such as TC scan o RMI (when renal failure is present), usually performed after macrohaematuria or abdominal or renal colics or renal failure. When fatty tissue cannot be demonstrated within renal lesion (as in the female case), biopsy can be undertaken to exclude malignancy. Histology at the edge of an AML may look like renal carcinoma, but recent studies suggest that it can be differentiated by staining for HMB-45 which is positive in AML and negative in carcinoma. Two cases of tuberous sclerosis with different neurological fenotype, with bilateral renal angiomyolipomatosis and heavy renal failure, are presented.

    Renal transplant recipients requiring aortic reconstruction due to abdominal aortic aneurysm (AAA) pose a unique clinical problem. The concern during surgery is causing ischemic injury to the renal allograft. A variety of strategies for protection of the renal allograft during AAA intervention have been described including a temporary shunt, cold renal perfusion, extracorporeal bypass, general hypothermia, and endovascular stent-grafting. In addition, some investigators have reported no remarkable complications of the renal allograft without any specific measures. We treated a case of AAA in a patient with a renal allograft using a temporary aortofemoral shunt with good result. Since this technique is safe and effective, it should be considered in similar patients with AAA and previously placed renal allografts.

    Renal involvement with amyloidosis is common but causes patient survival to be poor, rarely reaching 5 years. In this study, we retrospectively reviewed clinical and biological characteristics as well as treatments and outcomes of patients with renal amyloidosis followed for more than 5 years. Between 1975 and 2003, 485 patients were diagnosed with renal amyloidosis including only 12 patients who were followed more than 5 years. The six men and six women of mean age 42.4 years (range 18 to 66 years) displayed renal signs of lower limb edema in all cases; hypertension in four cases, proteinuria on urinalysis in all cases with microscopic hematuria in five cases. Biological tests showed nephrotic syndrome in 11 patients, normal renal function in nine patients, and renal failure in three patients whose mean creatinine was 481.6 micromol/L (range 294 to 726). The amyloidosis was AA type in 11 cases and non-AA in one case. An etiologic survey revealed spondylarthropathy in one patient, pulmonary tuberculosis in two patients, chronic bronchitis in three patients, hepatic hydatic cyst in one patient, Mediterranean familial fever in two patients, Crohn's disease in one patient, Hodgkin's lymphoma in one patient, and multiple myeloma in one patient. Specific treatment was initiated with colchicine in seven patients. At a 110-month mean follow-up (range 53 to 153 months), remission of nephrotic syndrome was observed in four cases, progression to chronic renal failure in two patients, and to end-stage renal failure in five cases (range 53 to 196 months), with stabilization of renal function in seven patients. In conclusion, primary amyloid disease should be optimally suppressed in patients with renal involvement. The role of this treatment in remission of renal amyloidosis is not well established. This efficacy of the treatment has been demonstrated in some patients with improved survival.

Spiral abdominopelvic computerized tomography (CT) scan showed multiloculated cystic mass (120 ×100 ×80 mm) in lower portion of left kidney with internal enhancing solid components and coarse peripheral calcifications. Radical nephrectomy of left kidney was done and biopsy confirmed renal cell carcinoma (RCC), papillary type, sarcomatoid foci, Fuhrman grade III. We assumed that, presence of nephrotic syndrome and paraneoplastic glomerulopathy leaded to heavy proteinuria in this case. Secondary, paraneoplastic glomerulopathy such as immunoglobulin A nephropathy and focal segmental glomerulosclerosis as a paraneoplastic syndrome of RCC have been reported previously. RCC can present with a wide range of signs and symptoms. Atypical presentations of papillary RCC such as proteinuria should be considered for patients presenting with nephrotic syndrome.

    Introduction Hypothyroidism is prevalent in India. Its association with renal diseases though not very common but have been described in many studies. Here we are reporting renal biopsy findings in 16 cases, all of whom were already diagnosed cases of hypothyroidism. Aim To study renal parenchymal diseases associated in patients with hypothyroidism. Materials and Methods Formalin fixed paraffin embedded sections of renal biopsy were examined after staining with H&E, PAS and Acid Fuschin Orange G (AFOG) stain. Serum urea/creatinine measurements done by semi-autoanalysers and urine analysis were done by using urine strips and light microscopy. Results In 16 cases, M:F ratio was 9:7. Duration of disease varied from 6 months to 14 years. Blood urea and serum creatinine were raised in 10 cases (62.5%) and nephrotic range proteinuria was present in 13 cases (81.25%). Two of the patients had co existing systemic lupus erythaematous. Renal pathology revealed membranous glomerulonephritis (GN) in both cases. In renal biopsy seven cases (43.75%) had pure Membranous Glomerulonephritis (MGN), 4 cases (25%) had mixture of Mesan-gial cell proliferation and membranous Glomerulonephritis(GN) also called MembranoProliferative GN (MPGN). Another four cases (25%) had Focal Segmental Glomerulosclerosis (FSGS) with chronic interstitial nephritis and one case was having minimal change disease. Conclusion Thus present study concludes that hypothyroidism can cause renal parenchymal disease like membranous GN, mesangiocapillary GN which is also called as membranoproliferative GN and FSGS.

    We report herein a 27-year-old male case of inherited distal renal tubular acidosis complicated with renal diabetes insipidus, the symptoms of which were aggravated by the occurrence of diabetes mellitus. At 2 months after birth, he was diagnosed as having inherited distal renal tubular acidosis and thereafter supplementation of both potassium and alkali was started to treat his hypokalemia and metabolic acidosis. At the age of 4 years, calcification of the bilateral renal medulla was detected by computed tomography. Subsequently his urinary volume gradually increased and polyuria of approximately 4 L/day persisted. At the age of 27 years, he became fond of sugar-sweetened drinks and also often forgot to take the medicine. He was admitted to our hospital due to polyuria of more than 10 L day, muscle weakness and gait disturbance. Laboratory tests disclosed worsening of both hypokalemia and metabolic acidosis in addition to severe hyperglycemia. It seemed likely that occurrence of diabetes mellitus and cessation of medications can induce osmotic diuresis and aggravate hypokalemia and metabolic acidosis. Consequently, severe dehydration, hypokalemia-induced damage of his urinary concentration ability and enhancement of the renin angiotensin system occurred and thereby possibly worsened his hypokalemia and metabolic acidosis. As normalization of hyperglycemia and metabolic acidosis might have exacerbated hypokalemia further, dehydration and hypokalemia were treated first. Following intensive treatment, these abnormalities were improved, but polyuria persisted. Elevated plasma antidiuretic hormone (12.0 pg/mL) and deficit of renal responses to antidiuretic hormone suggested that the polyuria was attributable to the preexisting renal diabetes insipidus possibly caused by bilateral renal medulla calcification. Thiazide diuretic or nonsteroidal anti-inflammatory drugs were not effective for the treatment of diabetes insipidus in the present case.

    A 59-year-old woman with end-stage renal disease of diabetic nephropathy who had been on maintenance hemodialisis for 4 years, underwent a living-unrelated renal transplantation 6 years ago. She was admitted to our hospital, because of a low grade fever and edema. Ultrasonography revealed the cyst with heterogeneity structure in the upper pole of the transplanted kidney. Magnetic resonance imaging showed a high-intensity cystic mass measuring 68×53 mm. As fever and laboratory data did not improve sufficiently by the treatment with antibiotics, echo-guided puncture and drainage were performed for the abnormal structure in the upper pole of the transplanted kidney. In the culture of the purulent aspirate drained from renal cyst, Escherichia coli was isolated. To our knowledge, this is the first report of infected renal cyst of the graft in a renal transplant recipient in the world. PMID:22075611

    A 46-year-old woman with sudden on set strong right flank pain was transferred to our hospital with the diagnosis of right renal infarction. Cardiac ultrasonography revealed a vegetation on the posterior cusp of the mitral valve, and the renal infarction was thought to be caused by renal artery embolism from infective endocarditis. Since the vegetation remained after antimicrobial therapy as conservative management, the patient was surgically treated by mitral annuloplasty. It has been known that infective endocarditis can cause renal infarction. Infective endocarditis requires immediate and adequate treatment because of high mortality. Therefore, the appropriate diagnosis of infective endocarditis is needed for patients with renal infarction without any other disorder causing renal infarction.

The diagnosis of kidney cancer is suspected and the patient underwent open radical nephrectomy, surrenalectomy and lymphadenectomy dissection. The pathologic examinations find a rosai dorfman disease. This unusual benign entity is uncommon in the kidney, but in medical imaging, it may simulate an infiltrative renal neoplasm, especially a lymphoma or leukemia or even renal cell carcinoma. A comprehensive literature review was undertaken to summarize the clinical and pathologic features of this disorder. PMID:27642405

    Nutcracker phenomenon or renal vein entrapment is classically seen as a compression of renal vein in between abdominal aorta and superior mesenteric artery with patients being asymptomatic or clinically manifested in the form of nutcracker syndrome as proteinuria, hematuria, flank pain, pelvic congestion in women, and varicocele in men. In this report, we are presenting a case of rare variant of nutcracker phenomenon along with brief review of anatomy, pathophysiology, public health, and clinical significance of nutcracker syndrome. On a routine dissection of an adult male cadaver, we noticed an unusual arrangement of the structures at the hilum of the left kidney showing entrapment of renal vein between left anterior inferior and posterior segmental renal arteries. The variation in the course of left anterior inferior segmental renal artery leads to compression of left renal vein at renal hilum. Therefore, we have named this rare abnormal anatomical entity as hilar nutcracker phenomenon. The structures in the right renal hilum are normal. The objective of this paper is to report an unusual but important variant of nutcracker phenomenon and also give collective knowledge of such anatomical variations in renal vasculature that will help in diagnosing and treating such rare renal disorder.

    AA amyloidosis is a disorder characterized by the abnormal formation, accumulation and systemic deposition of fibrillary material that frequently involves the kidney. Recurrent AA amyloidosis in the renal allograft has been documented in patients with tuberculosis, familial Mediterranean fever, ankylosing spondylitis, chronic pyelonephritis and rheumatoid arthritis. De novo AA amyloidosis is rarely described. We report two cases of AA amyloidosis in the renal allograft. Our first case is a 47-year-old male with a history of ankylosing spondylitis who developed end-stage renal disease reportedly from tubulointerstitial nephritis from non-steroidal anti-inflammatory agent use. A biopsy was never performed. One year after transplantation, AA amyloidosis was identified in the femoral head and 8 years post-transplantation, AA amyloidosis was identified in the renal allograft. He was treated with colchicine and adalimumab and has stable renal function at 1 year-follow-up. Our second case is a 57-year-old male with a long history of intravenous drug use and hepatitis C infection who developed end-stage kidney disease due to AA amyloidosis. Our second patient's course was complicated by renal adenovirus, pulmonary aspergillosis and hepatitis C with AA amyloidosis subsequently being identified in the allograft 2.5 years post-transplantation. Renal allograft function remains stable 4-years post-transplantation. These reports describe clinical and pathologic features of two cases of AA amyloidosis presenting with proteinuria and focal involvement of the renal allograft.

    Gastroduodenal ulcers in renal transplant recipients are usually originated from excessive acid secretion or infection of Helicobacter pyroli. Herein, we report a case of cytomegalovirus (CMV)--induced gastric ulcer following cadaveric renal transplantation. The patient was a 48-year-old man with chronic renal failure and received cadaveric renal transplantation. A month later, he had epigastralgia without CMV-positive antigenemia and received gastrointestinal fiberscopy. Endoscopically, gastric ulcer was identified. Histological findings revealed conspicious nuclear enlargement of the non-epithelial cells in the ulcer bed, which indicated CMV infection. The patient was treated with ganciclovir for 2 weeks and the symptom was relieved. He discharged with a good renal function on day 75 posttransplant. CMV infection plays an important role in gastric ulcer after renal transplantation. Antigenemia assay dose not seem feasible for the detection of CMV-induced gastric ulcer. PMID:15508703

    Solitary fibrous tumors (SFTs) are unusual spindle cell neoplasms initially described in the pleura but have since been discovered in many extrapleural locations. SFT of the kidney is extremely rare, the majority occurring in middle-aged adults. To date, only two pediatric cases of renal SFT have been reported. We report a case of large SFT in the kidney of a 3-year-old boy that was clinically and radiologically thought to be a nephroblastoma. This case is the first pediatric renal SFT to be reported with detailed histopathologic and cytogenetic analyses. SFT should be included in the differential diagnosis of pediatric renal tumors.

    A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used. Although considered to be accompanied with risks of bleeding, bowel injury, and renal dysfunction, PNL is effective for urinary lithiasis after renal transplantation. TUL is less invasive, but access may be difficult when the ureter has an unusual course or ureteral stricture exists, as in our patient. PMID:27018408

    ABSTRACT Familial juvenile nephronophtisis, an autosomal recessive tubulointerstitial chronic nephritis, is characterized by progressive renal disease and end stage renal failure, which require kidney transplantation. Post-transplant diabetes mellitus (PTDM) incidence after kidney transplantation varies from 4–25%. Obesity, positive oral glucose tolerance test, metabolic syndromes, and post–transplantation multi-drug, high dose, long-term immunosuppressive therapy are the risk factors incriminated. We present the case of a 15-year-old overweight boy who was diagnosed with familial juvenile nephronophtisis five years before, afterwards progressive renal disease and end stage renal failure. This young patient developed PTDM three years after renal transplantation. His underweight brother, with the same medical history, did not develop PTDM. Transplantation was mandatory for a child with familial juvenile nephronophtisis. The case illustrates the risk factors for PTDM. PMID:24023594

    Authors report clinicopathological features of an unusual case of composite renal lesion occuring in 32-year-old Caucasian male. The patient was followed for cystic lesion of retroperitoneal-renal region for 5 years. He was indicated for resection of the cystic lesion because of changes of the retroperitoneal mass on CT scan. A cyst was located on upper renal pole. A huge cystic mass filled mainly by necrotic material was resected and submitted for histological examination. The wall of the cyst was composed of fibrous tissue, indistinguishable from inflammatory pseudotumor on histological level. The vital intracystic tissue was formed by well-differentiated papillary renal cell carcinoma. The most important step within differential diagnosis is distinguishing of sarcomatoid differentiation in renal cell carcinoma. This very rare case demonstrates the importance of careful examination of all spindle cell lesions of the kidney.

    A right renal cyst was found in a 69-year-old man with stage IV chronic kidney disease on abdominal ultrasonography performed to investigate a right upper abdominal swelling. Aspiration cytology of the cyst revealed no malignancy, but malignancy could not be ruled out on magnetic resonance imaging because of the cyst's wall thickness and heterogeneous contents. At one-year of follow-up, emergent abdominal surgery was performed due to incidental perforation of ascending colon diverticulitis. At that time, cystic fenestration was performed because the large renal cyst obstructed the operative procedure. Pathological examination showed type-1 papillary renal cell carcinoma, and radical nephrectomy was performed after the patient's general condition improved. Hemodialysis was started after the operation, and there has been no disease recurrence for two years. PMID:23328163

The serum creatinine concentration at the time of presentation ranged from 265 to 1380 μmol/l (3.0 to 15.6 mg/dl), with a mean of 787 μmol/l (8.9 mg/dl). Although only two patients were hypercalcemic at the time of presentation, the 24-hour urinary excretion of calcium was increased in three of the four patients in whom it was measured, and renal calculi were present in one case. Renal biopsy revealed interstitial nephritis and tubular atrophy in all cases, as well as nephrocalcinosis in three cases and noncaseating granulomas negative for acid-fast bacilli in four cases. In each patient steroid therapy led to a rapid improvement in renal function (mean post-treatment serum creatinine level 274 μmol/l [3.1 mg/dl]). The follow-up period ranged from 8 months to 8 years (mean 3.0 years). In three patients renal function remained stable with low-dose steroid therapy. In two cases recurrent hypercalcemia and deteriorating renal function accompanied steroid withdrawal but resolved with its reinstitution. In one additional case reversible deterioration in renal function accompanied tapering of the steroid dose; however, there was no hypercalcemia. This report emphasizes the importance of considering sarcoidosis in the differential diagnosis of acute renal failure of unknown origin. Long-term follow-up of such patients is essential, as relapse is common. ImagesFIG. 1FIG. 2FIG. 3 PMID:519562

    Numerous cases of enamel renal syndrome have been previously reported. Various terms, such as enamel renal syndrome, amelogenesis imperfecta and gingival fibromatosis syndrome, and enamel-renal-gingival syndrome, have been used for patients presenting with the dental phenotype characteristic of this condition, nephrocalcinosis or nephrolithiasis, and gingival findings. This report describes a case of amelogenesis imperfecta of the enamel agenesis variety with nephrolithiasis in a 21-year-old male patient who complained of small teeth. The imaging modalities employed were conventional radiography, cone-beam computed tomography, and renal sonography. Such cases are first encountered by dentists, as other organ or metabolic diseases are generally hidden. Hence, cases of amelogenesis imperfecta should be subjected to advanced diagnostic modalities, incorporating both dental and medical criteria, in order to facilitate comprehensive long-term management.

    A case of false positive I-131 MIBG imaging for detection of pheochromocytoma is presented. There was an area of increased tracer uptake in the left renal region that showed steadily reducing activity over a period of three days. This raised the suspicion of a dilated renal pelvis, which was later confirmed by Tc-99m DTPA imaging. It is advisable in cases of ambiguous I-131 MIBG imaging to use Tc-99m DTPA rather than Tc-99m DMSA for localizing the kidneys and renal pelvis.

    Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vascular structures at the hilum of the kidney in terms of their pattern of arrangement and division. The present paper describes a bilateral anomalous arrangement of the structures at the renal hilum as well as their peculiar branching pattern which is of clinical and surgical relevance. Multiple branching of the renal vessels was observed in both kidneys due to which the hila were congested. The right renal artery immediately after its origin divided into 2 branches. The upper branch represented an aberrant artery whereas the lower branch gave 5 divisions. The left renal artery also divided into 2 branches much before the hilum as anterior and posterior divisions. The anterior branch took an arched course and gave 6 branches. The posterior branch gave 3 terminal branches before entering the renal substance. In addition to anomalous hilar structures, normal architecture of both kidneys was altered and the hilum of the left kidney was found on its anterior surface. PMID:23346454

    During routine dissection which was carried out for the medical students, a circumaortic left renal vein draining into inferior vena cava was observed. There were 2 renal veins through which the left kidney drained into the inferior vena cava, of which the larger one ran ventral to aorta and the other smaller one ran posterior to aorta and received lumbar veins before opening into inferior vena cava. This is a relatively rare condition which can result in left renal hypertension (LRVH) syndrome which is otherwise called as anterior and posterior nutcracker syndromes. This venous anomaly results from the errors of embryological development. It is of clinical significance, mainly during retroperitoneal surgeries and intra caval interventions. It is also important in conditions which warrant extensive venous dissections, venous reconstructions as in transplantations and invasion of veins by cancerous tissue, resulting in life threatening haemorrhage.

    Renal biopsy is one of the pivotal diagnostic tools used in the field of nephrology. A morphological analysis of the kidney may also be of value for the overall management of patients with diabetic nephropathy. However, the indications for renal biopsy differ considerably among nephrologists, and no global consensus regarding performing this procedure among diabetic patients with various renal manifestations has yet been achieved. In this report, we would like to describe our serendipitous experience with a male type 2 diabetic patient presenting with nephrotic syndrome complicated by concurrent gastric carcinoma. We also discuss several conundrums that arose in the current case, which had an impact on our diagnostic and therapeutic decisions.

    Renal infarction secondary to thromboembolism is usually a sequela of cardiac disease, the heart being the source of systemic arterial emboli in up to 94% of cases; the three major causes are: atrial fibrillation, myocardial infarction and rheumatic mitral stenosis. Renal infarction is often confused with other conditions due to similar presenting symptoms. This leads to delay in initiating treatment and significantly decreases the chances of renal salvage. We report a sonographic diagnosis in 39-year-old man, with risk factors for thrombosis, without a prior history of thromboembolism.

    Renal vein thrombosis (RVT) is an uncommon condition in adults and may be caused by endothelial damage, stasis, or hypercoagulable states. RVT is commonly identified in patients with nephrotic syndrome or malignancy. We present the case of a 57-yearold man with no past medical history who presented with a 1-month history of abdominal pain, dysuria, and hematuria. Initial laboratory studies were consistent with acute kidney injury (AKI). Imaging revealed bladder distension, enlargement of the prostate, bilateral hydronephrosis, and left renal vein thrombosis extending into the inferior vena cava. His renal failure and presenting symptoms resolved with placement of a Foley catheter and ureteral stent. The patient was discharged on anticoagulation. Here, we report a rare case of RVT that appears to have occurred as a consequence of obstructive uropathy causing massive bladder distention resulting in compression of the renal vein.

    We report the case of a 33-year-old male with hypothyroidism who developed acute renal impairment with rhabdomyolysis after strenuous physical activity (snow shoveling). His thyroid function test confirmed marked hypothyroidism. Severe elevation of serum CK consistent with rhabdomyolysis was noted and an elevated creatinine indicated acute renal impairment. Patient's condition improved significantly after starting him on thyroid hormone replacement therapy and aggressive hydration. Acute renal impairment with rhabdomyolysis in patients with hypothyroidism is quite rare and we expect that this case report adds to the existing literature on this subject. We also emphasize that thyroid status should be evaluated in patients with unexplained acute renal impairment and presenting with the symptoms of muscle involvement. PMID:24822067

    Objective The aim of this case report is to discuss the clinicopathological features of a patient with a primary renal carcinoid tumor. Methods We report on the clinical and pathological information of one case of a patient with a primary renal carcinoid tumor as well as review relative literature. Results The patient was diagnosed with a renal tumor when she received physical examination, and exhibited no positive symptoms. The diameter of tumor was 5 cm, the cross surface of the tumor was light yellow and firm, and the central part was soft with hemorrhage and necrosis. Immunohistochemical staining revealed strong and diffuse staining with synaptophysin, chromogranin A, and neuron-specific enolase. Conclusion A primary renal carcinoid tumor is extremely rare. Surgical resection is a preferred therapeutic method. PMID:26966374

    The relationships between ambient PM(2.5) and PM(10) and arrhythmia and the effect modification by cigarette smoking were investigated. Data from U.S. Environmental Protection Agency (EPA) air quality monitors and an established national-scale, log-normal kriging method were used to spatially estimate daily mean concentrations of PM at addresses of 57,422 individuals from 59 examination sites in 24 U.S. states in 1999-2004. The acute and subacute exposures were estimated as mean, geocoded address-specific PM concentrations on the day of, 0-2 d before, and averaged over 30 d before the electrocardiogram (ECG) (Lag(0); Lag(1); Lag(2); Lag(1-30)). At the time of standard 12-lead resting ECG, the mean age (SD) of participants was 67.5 (6.9) yr (84% non-Hispanic White; 6% current smoker; 15% with coronary heart disease; 5% with ectopy). After the identification of significant effect modifiers, two-stage random-effects models were used to calculate center-pooled odds ratios and 95% confidence intervals (OR, 95% CI) of arrhythmia per 10 mug/m(3) increase in PM concentrations. Among current smokers, Lag(0) and Lag(1) PM concentrations were significantly associated ventricular ectopy (VE)-the OR (95% CI) for VE among current smokers was 2 (1.32-3.3) and 1.32 (1.07-1.65) at Lag(1) PM(2.5) and PM(10), respectively. The interactions between current smoking and acute exposures (Lag(0); Lag(1); Lag(2)) were significant in relationship to VE. Acute exposures were not significantly associated with supraventricular ectopy (SVE), or with VE among nonsmokers. Subacute (Lag(1-30)) exposures were not significantly associated with arrhythmia. Acute PM(2.5) and PM(10) exposure is directly associated with the odds of VE among smokers, suggesting that they are more vulnerable to the arrhythmogenic effects of PM.

    A 59-year-old woman consulted our hospital for a left renal mass which she had been aware of for 4 years. The tumor was in the lower portion of the left kidney. It was a cystic tumor whose wall was enhanced on computed tomography and magnetic resonance imaging. The lesion 3.0 cm in diameter, which was enhanced equally to the aorta, was found in a part of the wall. It was thought to be a pseudoaneurysm by renal angiography. We suspected a cystic renal cell carcinoma because of the plural feeding arteries and tumor staining, and performed left total nephrectomy. Pathological diagnosis was angiomyolipoma with few fat components. To our knowledge only 3 previous cases of renal angiomyolipoma with marked cystic degeneration have been reported in Japan. In all 3 cases, it was difficult in preoperative diagnosis to distinguish angiomyolipoma with cystic degeneration from cystic renal cell carcinoma complicated cyst. Moreover, this is the first reported case of renal angiomyolipoma with marked cystic degeneration and pseudoaneurysm.

    Polycythaemia vera represents a rare chronic myeloproliferative neoplasm characterized by an increased thrombotic risk. Previous case reports have documented a link between primary or secondary polycythemia and the presence of renal artery stenosis and renovascular hypertension. Herein, we report an exceptional case of renal artery restenosis leading to uncontrolled hypertension in a patient with PV and high haematocrit levels. A 52-year-old female patient with a history of polycythaemia vera under treatment with hydroxyurea and phlebotomy presented in our outpatient clinic with newly diagnosed hypertension caused by left renal artery stenosis. Six months after stenting, patient returned for a follow-up visit due to uncontrolled hypertension and high haematocrit levels. Total restenosis of the left renal artery was found. Patient received optical medical treatment and was prescribed to higher doses of hydroxyurea by her treating haematologist. Since then, blood pressure and Hct levels remain adequately controlled. As described by earlier case reports, renal artery stenosis, hypertension and polycythemia often coexist. However, renovascular hypertension may not only lead to secondary erythrocytosis but also be a thrombotic complication of primary erythrocytosis. Thus, patients with polycythaemia vera should be carefully evaluated and optimally managed when hypertension or impaired renal function coexist. PMID:24991947

    Clear cell papillary renal cell carcinoma (CCPRCC) was recently included in the International Society of Urological Pathology Vancouver Classification of Renal Neoplasia as a subtype of RCC that is morphologically, immunohistochemically, and genetically distinct from both clear cell renal cell carcinoma (CCRCC) and papillary renal cell carcinoma. In our clinical practice we have observed tumors with overlapping histologic features of CCPRCC and CCRCC; therefore, our aim was to describe the morphologic, immunohistochemical, and clinical characteristics of these tumors. We examined a large series of consecutive nephrectomies diagnosed as CCRCC and found 37 tumors with morphologic overlap between CCRCC and CCPRCC, identifying 2 patterns. Pattern 1 tumors (N=19) had areas diagnosable as CCRCC admixed with foci having a prominent linear arrangement of nuclei away from the basement membrane imparting a resemblance to CCPRCC; however, other morphologic features commonly seen in CCPRCC (such as branching acini and cystic spaces with papillary tufts) were not typical and, when present, were focal or poorly developed. Pattern 2 (N=18) tumors had 2 discrete areas, one area with an appearance strongly resembling CCPRCC and the other with higher grade nuclei and features diagnosable as CCRCC, sometimes including rhabdoid differentiation, sarcomatoid differentiation, necrosis, and high-stage disease. Four (21%) of the pattern 1 tumors had grade 3 nuclei in the CCRCC-like areas, and 4 were high stage (pT3a). Of the 16 immunostained pattern 1 tumors, all expressed cytokeratin 7 (CK7) at least focally in the CCPRCC-like areas, strongly and diffusely in 9 (56%) cases; 12 (75%) showed negative to focal and/or weak CK7 expression in the CCRCC-like areas. CD10, α-methylacyl-CoA-racemase, high-molecular-weight cytokeratin, and carbonic anhydrase IX (CA IX) had no significant differential expression between these foci. No cup-like staining pattern was seen with CA IX. Two (11%) patients

    Isolated extrarenal retroperitoneal and renal echinococcal cysts are rare manifestations of hydatid disease. We report 23 cases of renal and other retroperitoneal hydatid cysts diagnosed and treated in our clinic. Flank pain, abdominal mass and non-specific symptoms such as nausea and vomiting were the major symptoms. Indirect haemagglutination test was positive in 18 cases and eosinophilia in four cases. Among imaging studies computerized tomography was the most valuable diagnostic examination. A high index of suspicion is needed for preoperative diagnosis of hydatid disease of kidney and retroperitoneum.

    A range of cancer types, at increased rates, is described in renal transplant recipients receiving immunosuppression. Aside from immunodeficiency, heightened medical surveillance for cancer, lifestyle, and other risk factors all play a role. Although the relation between cancer risk and degree of immunodeficiency might not be linear, and might be different for a wide range of cancer subtypes, human papillomavirus-related cancers in long-term transplant recipients may suggest the role of even modest immunosuppression, when present long enough. High-risk human papillomavirus types are recognized as the cause of cancer of the cervix. We report a 49-year-old female renal transplant recipient diagnosed with cervical squamous cell carcinoma, 5 years after the transplant. Based on this patient, we highlight difficulties in surgical approach and the importance of close clinical follow-up including regular gynecologic screening for cervical premalignant and malignant lesions.

    A 71-year-old man who had been treated conservatively for advanced prostate cancer with hormonal therapy presented with complaint of left flank pain. Intravenous urography demonstrated obstruction caused by a left upper ureteral calculus and leakage of contrast medium outside the renal pelvis and calyces. Left percutaneous nephrostomy was performed, and subsequent nephrostography showed extravasation into a parapelvic renal sinus cyst previously recognized on follow-up computed tomography (CT). The left ureteral calculus was treated with extracorporeal shock wave lithotripsy (ESWL), after which obstruction and extravasation disappeared. One month later, abdominal CT demonstrated no left renal nor ureteral calculi, as well as a reduction in the left renal sinus cyst. Urinary extravasation sometimes occurs as a complication of acute urinary obstruction. However, extravasation into a cyst is very rare. We have found only one case reported in the literature, so far.

    Cyclosporine can cause acute and chronic nephrotoxicity. Renal biopsy is a reliable tool for the diagnosis of cyclosporine nephrotoxicity. The authors report a 56-year-old Thai female with a history of end-stage renal disease who underwent cadaveric renal transplantation. A transplanted kidney biopsy was performed on day 9 post-transplant to identify the cause of delayed graft function. Light and electron microscopic findings revealed widespread (> 50% involvement) numerous tubules filled with uniformly-sized vacuoles in cytoplasm (isometric vacuolization). Serum cyclosporine trough level was 534 ng/mL. Neither acute rejection nor acute tubular necrosis was seen. Diagnosis of acute cyclosporine nephrotoxicity was made. Isometric vacuolization in more than 50% involvement of the tubules is rare (3%) in biopsy specimens. The tubular isometric vacuolization might not have the strong impact to the long term graft outcome. This is the first case report of isometric tubular vacuolization due to cyclosporine toxicity in renal transplant recipient in Thailand.

    Hypoparathyroidism is an uncommon disease and its coexistence with chronic renal failure is quite rare. Hypocalcemia and hyperphosphatemia are seen in both diseases. Diagnosis of hypoparathyroidism may be overlooked when parathormone response is not evaluated in patients with chronic renal failure. A 19-year-old female patient who had been receiving hemodialysis for 3 years because of chronic renal failure was diagnosed as idiopathic hypoparathyroidism and hashimoto thyroiditis. When her medical records on the first admission and medical history were evaluated, hypoparathyroidism and hashimoto thyroiditis were seen to be present also when she was started hemodialysis. Idiopathic hypoparathyroidism should be suspected in case as absence of parathormone response to hypocalcemia in patients with chronic renal failure. It should be taken into consideration that hashimoto thyroiditis may accompany and required analysis should be done.

    Renal oncocytoma is one of the most unusual benign lesion, which are usually diagnosed postoperatively, since their differentiation from renal cell carcinoma is challenging. The present study reports two cases of renal oncocytoma in a 60-year-old woman and a 46-year-old man. Relevant clinical and pathological data on the two patients were retrieved. The tumors were excised and the patients underwent laparoscopic radical nephrectomy. Typical features of oncocytoma were observed upon histological examination of the excised specimens. The postoperative course of each patient was uneventful and they were discharged 8 and 7 days post-surgery, respectively. In addition, the current study presents the results of a literature review regarding the radiological, immunohistochemical and pathological characteristics of renal oncocytoma. PMID:27347140

    Background Cocaine abuse has been known to have detrimental effects on the cardiovascular system. Its toxicity has been associated with myocardial ischemia, cerebrovascular accidents and mesenteric ischemia. The pathophysiology of cocaine-related renal injury is multifactorial and involves renal hemodynamic changes, alterations in glomerular matrix synthesis, degradation and oxidative stress, and possibly induction of renal atherogenesis. Renal infarction as a result of cocaine exposure, however, is rarely reported in the literature. Case presentation A 48 year-old male presented with a four-day history of severe right flank pain following cocaine use. On presentation, he was tachycardic, febrile and had severe right costovertebral angle tenderness. He had significant proteinuria, leukocytosis and elevated serum creatinine and lactate dehydrogenase. Radiographic imaging studies as well as other screening tests for thromboembolic events, hypercoagulability states, collagen vascular diseases and lipid disorders were suggestive of Cocaine-Induced Renal Infarction (CIRI) by exclusion. Conclusion In a patient with a history of cocaine abuse presenting with fevers and flank pain suggestive of urinary tract infection or nephrolithiasis, cocaine-induced renal infarction must be considered in the differential diagnosis. In this article, we discuss the prior reported cases of CIRI and thoroughly review the literature available on this disorder. This is important for several reasons. First, it will allow us to discuss and elaborate on the mechanism of renal injury caused by cocaine. In addition, this review will demonstrate the importance of considering the diagnosis of CIRI in a patient with documented cocaine use and an atypical presentation of acute renal injury. Finally, we will emphasize the need for a consensus on optimal treatment of this disease, for which therapy is not yet standardized. PMID:16176587

    Schwannoma is a benign soft tissue tumor of neural origin arising from the Schwann cells of the neural sheath. It has rarely been reported in renal or perirenal region. The preoperative diagnosis has mostly been confused with renal cell carcinoma in this location in most previous reports. We report a case that presented with a large "simple cystic" mass at the renal hilum. The preoperative differential diagnosis included hilar renal cortical cyst, renal sinus cyst, ureteropelvic junction obstruction (UPJO), or even a hydatid cyst. The final diagnosis was clinched only on histopathological examination.

    The infectious origin of non-traumatic rhabdomyolysis is rare (5% of cases). An elevated muscle enzyme level is often reported in the legionnaire's disease. We report the case of a 39-year-old male, with no previous medical history, admitted for renal failure (creatininemia=977 micromol/l) secondary to rhabdomyolysis and a twelve-day history of infectious syndrome with pneumonia in the left base. Legionella pneumophila was considered responsible for these symptoms because of a positive serology. The other microbial assessments were negative. After rehydration and three weeks of antibiotics, the outcome was favorable: the renal failure resolved completely and the muscle enzyme level returned to normal.

    Wegener's granulomatosis (WG) is a necrotizing granulomatous vasculitis involving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glomerulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bilateral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment. PMID:22382229

    Calciphylaxis is characterized by progressive vascular calcification, soft tissue necrosis, and ischemic necrosis of the skin. The condition is usually associated with end-stage renal disease and has a poor prognosis. We present a 76-year-old man on hemodialysis who developed small, painful purpura on the thigh. The purpura rapidly spread to his back and hip and became ulcerated. Histological examination of a skin biopsy revealed arterial calcification in the subcutaneous adipose tissue. We therefore diagnosed calciphylaxis and administered intravenous antibiotics and debrided the necrotic soft tissue. However, the lesions did not heal and the patient died from sepsis related to cellulitis. PMID:21063168

    Multiple primary neoplasms are not common, those containing renal neurilemoma are even more rare. Our study involves the diagnosis and treatment of a female patient with multiple primary neoplasms with renal neurilemoma. She was previously diagnosed with left ovarian dermoid cyst, right posterior mediastinal neurilemmoma, left forearm neurilemmoma, and papillary thyroid carcinoma, underwent operation treatment. Physical examination reveals a left renal mass with a left adrenal tumor a month before, and underwent retroperitoneal laparoscopic left adrenal nodule resection and left partial nephrectomy. Operation was successful, without conversions to open. Artery occlusion time was 18 min, and blood loss was 20 mL. Post operation pathologic result shows a left renal cellular leiomyoma neurilemmoma with focal cystic change, and tumor diameter was about 3 cm. Immunohistochemistry reports S-100 (+), Ki-67 (15%+), and short-term follow-up without recurrence. In our case of study, even though the tumors were heterochronism, they were both treated with surgical resection. Renal neurilemoma is benign. Laparoscopic partial nephrectomy is not only minimally invasive, fast in recovery, but most importantly preserves renal tissue to the largest extent. It can prevent preoperative pathological uncertainty, which often undergoes radical nephrectomy.

    Malakoplakia is an unusual chronic inflammatory disease related to prior urinary tract infection. It is characterized by the presence of macrophages with foamy cytoplasm exhibiting larger PAS positive inclusions that stain for calcium and iron. Malakoplakia affects renal allograft and is associated with severe morbidity. Herein, the authors report a new case of renal graft malakoplakia in a 23-year-old female patient. The patient received a living-related donor renal transplantation with a high immunological risk. Plasmapheresis and intravenous immunoglobulin (i.v. Ig) treatment, pre- and post-transplant, and induction with rabbit anti-thymocyte globulins were used due to presence of donor specific antibodies and positive B cross match by flow cytometry. The patient had an early urinary tract infection with a good outcome. On Day 36 post-transplant (PO), the patient returned to the clinic with fever, graft pain and acute renal dysfunction leading to hemodialysis. Escherichia coli (E. coli) was present in the blood and urine culture. At the time, the renal biopsy revealed numerous sheets of macrophages with foamy, eosinophilic cytoplasm showing several PAS positive granules and large inclusions that stained strongly with hematoxylin, calcium (von Kossa method) and iron (Prussian blue). The patient was diagnosed with malakoplakia related to a kidney transplant. Despite prolonged treatment with antibiotics, determined by a susceptibility test, the patient did not recover renal function and remained on dialysis. PMID:23195831

    Most of the reports of oxalic acid intoxication are in cases of ethylene glycol intoxication. These symptoms are known to be central nerve system manifestations, cardiopulmonary manifestations and acute renal failure. There have been only a few reports of direct oxalic acid intoxication. However, there have been a few recent reports of oxalic acid intoxication due to the ingestion of star fruit and ascorbic acid. We herein report the case of a patient with acute renal failure and metabolic acidosis caused directly by consumption of oxalic acid. During the initial examination by the physician at our hospital, the patient presented with tachypnea, a precordinal burning sensation, nausea and metabolic acidosis. After admission, the patient developed renal failure and anion gap high metabolic acidosis, but did not develop any CNS or cardio-pulmonary manifestations in the clinical course. The patient benefitted symptomatically from hemodialysis.

    Dengue is an emerging, rapidly expanding disease, whose clinical and biological manifestations vary. Kidney injury is not usual but can be severe, and it is most often associated with dengue hemorrhagic fever or shock. Guadeloupe, which is located in an endemic area, experienced an epidemic from 2013 to 2014. During this outbreak, a case of renal failure during dengue was observed in a 10-year-old child. No evidence of dengue hemorrhagic fever or shock syndrome was found. The clinical and biological course improved with symptomatic treatment. The association of acute renal failure with hemolytic anemia suggested a diagnosis of hemolytic uremic syndrome. However, this could not be confirmed in the absence of thrombocytopenia and cytopathologic evidence. This case illustrates the diversity of clinical presentations of dengue, and the possibility of severe renal impairment unrelated to the usual factors encountered in dengue.

    Renal cell carcinoma (RCC) accounts for approximately 3% of all cancer cases. RCCs usually metastasize to the lungs, bones, liver, or brain. Only <1% of patients with bone metastases manifested clavicular RCC metastases. Thus, clavicular metastasis as the initial presentation of RCC is extremely rare. We report a patient with RCC metastasis to the left clavicle, which was first presented with pain caused by a pathological fracture. Magnetic resonance image revealed a renal tumor, and technetium-99m–methylene diphosphonate bone scintigraphy showed multiple osseous metastases. The patient eventually underwent surgery to remove the lateral end of the left clavicle and right kidney. Histopathology revealed renal tumor and clear cell carcinoma in the clavicle. Finally, we review 17 cases of clavicular metastases originating from different malignancies. PMID:26779378

    An 86-year-old woman with a 13-year history of hypertension was admitted because of consciousness disturbance, hypotension, tachycardia, and cyanosis at her extremities. Enhanced computed tomography showed a thrombus in the truncus pulmonalis and right pulmonary artery, and also showed a left renal mass and a right renal cyst. Under a diagnosis of pulmonary embolism we started anticoagulant therapy, but the patient died five days after admission. At autopsy, a saddle-like thrombus was found in the truncus pulmonalis and bilateral trunks of pulmonary arteries. Microscopic examination showed smooth muscle cells in the thrombus. We could not find any other thrombus in the inferior vena cava, intrapelvic veins, nor in veins of lower extremities by milking. We also found tumors in both kidneys. Microscopically all tumors were diagnosed as angiomyolipoma. There were many fibrin thrombi in the sinuses of the tumors but there was no evidence of malignancy. We finally diagnosed pulmonary embolism due to renal angiomyolipoma because there was no other thrombus origin and microscopically the same smooth muscle cells were found both in the renal tumor and the pulmonary thrombus. There is only one case report concerning pulmonary embolism due to renal angiomyolipoma which happened during operative treatment. The treatment method of renal angiomyolipoma is determined by tumor size and symptoms, and usually intensive treatment is not performed in cases without symptoms. Our patient had no symptoms until the onset of severe complication of pulmonary embolism, suggesting that radical treatment is necessary for renal angiomyolipoma with a thrombus even when there are no symptoms.

    Introduction: Renal transplantation are admitted to emergency department (ED) more than normal population. The present brief report aimed to determine the reasons of renal transplant patients’ ED visits. Methods: This retrospective case series study analyzed the reasons of renal transplant recipients’ admission to one ED between 2011 and 2014. The patient data were collected via a checklist and presented using descriptive statistics tools. Results: 41 patients with the mean age of 40.63 ± 10.95 years were studied (60.9% male). The most common ED presenting complaints were fever (36.6%) and abdominal pain (26.8%). Infections were the most common final diagnosis (68.3%). Among non-infectious causes, the most common was acute renal failure (9.7 %). 73.2% of the patients were hospitalized and no cases of graft loss and mortality were seen. Conclusion: The most common reason for ED admission was fever, and infections were the most common diagnosis. Acute gastroenteritis being the most frequent infection and among non-infectious problems, acute renal failure was the most frequent one. PMID:27800542

    Clear cell papillary renal cell carcinoma (CCPRCC) is a newly described variant of renal cell carcinoma (RCC) which is composed mainly of cells with clear cytoplasm arranged in cystic and papillary patterns. We report the clinicopathologic features, prognosis and differential diagnosis of 6 Clear Cell Papillary Renal Cell Carcinomas. The clinical information and follow-up data were analyzed. The patients were six males with median age of 52.5 years. Case 1 revealed dense calcification and ossification. Cases 2 and 3 contain a variably prominent smooth muscle stromal component. CA-IX, CK7, PAX-8 and VIM were positive in all cases. TFE3 and AMACR were not expressed in any tumor. CD10 was negative in 5 of 6 cases .The patients were followed for 13~55 months with no local tumor recurrences and tumor metastasis. The CCPRCC was associated with a more favorable outcome. These were low-grade and low-stage renal tumors. No lymph node or distant metastasis of the six tumors. PMID:26191150

    Hantavirus infection is seldom reported in Taiwan. The spectrum of clinical severity ranges from mild to severe and may cover Hantavirus pulmonary syndrome and hemorrhagic fever with renal syndrome (HFRS). We report a case of HFRS in a 24-year-old soldier presenting with fever, chills, abdominal pain and generalized myalgia. His clinical course progressed through febrile, hypotensive, oliguria and polyuria phases. Hantavirus infection was proven by serology at the second hospital week. The patient was successfully treated with supportive management. Clinicians should be alert to the possibility of HFRS when examining patients with symptoms of fever, renal function impairment, hemorrhagic tendency and with rural exposure in Taiwan.

    Renal involvement is most often seen in conjunction with multisystemic, disseminated lymphoma either by direct extension from a retroperitoneal mass or via hematogenous spread. Primary lymphoma of the kidney is not a common entity and it is a controversial issue on account of the absence of lymphatic tissues in the normal kidney. In this case report, we describe a 19-year-old male with hematuria, acute kidney injury, and bilateral renal masses due to massive lymphomatous infiltration of the kidneys, which was diagnosed as diffuse large B-cell non-Hodgkin lymphoma by Tru-Cut biopsy.

    Renal transplant patients are at high risk of developing various infections causing morbidity and mortality. Invasive fungal infection has been recognized as a significant complication of organ transplantation. The major fungal infections in these patients are due to candida, aspergillus and mucormycosis. However, infection because of infrequently encountered fungi like hyaline molds, dematiaceous filamentous fungi and zygomycetes are increasing in immunocompromised hosts. Dematiaceous fungi are recognized pathogens in organ transplant recipients with skin and soft tissue infection. We report the case of a 37-year-old man, a renal transplant recipient who developed an asymptomatic dematiaceous fungal infection in submandibular salivary gland. He recovered after excision and antifungal therapy. PMID:27656452

    We present a unique case of acute bacterial prostatitis caused by a very rare human pathogen, Raoultella planticola, in a renal allograft recipient 3.5 months post transplantation. Only a few cases of human infection by this pathogen have been reported worldwide. The present study reports the case of a 67-year-old man who was admitted to our transplant unit 3.5 months post transplantation with fever, dysuria, suprapubic pain, symptoms and signs of acute prostatitis, and elevated markers of inflammation and prostate-specific antigen. R. planticola was isolated in the urine culture. The patient was treated with ciprofloxacin (based on the antibiogram) and had a full recovery, with satisfactory renal function. To the best of our knowledge, this is not only the first reported case of R. planticola prostatitis, but also the first report of such an infection in a solid organ transplant recipient or in a patient on immunosuppressive medication.

    Primary localized amyloidomas of the renal pelvis are challenging to diagnose, due to non-specific imaging results and the unusual location. The present study reports a rare case of primary localized amyloidoma of the renal pelvis and aims to illustrate the challenges in pre-operatively discriminating between this disease and transitional cell carcinomas. The present study identified that the mass was situated in the left renal pelvis using ultrasonography. A nephroureterectomy was performed following careful preparation. Finally, histopathological studies revealed that the tumor consisted of massive diffuse deposits of amyloid and microscopic amorphous eosinophilic material, which stained positively for Congo red, demonstrating potassium permanganate digestion. Consequently, a diagnosis of amyloid light chain-type amyloidoma was determined. Systematic examinations were performed following the unexpected diagnosis, which eliminated the possibility of amyloid associated-type amyloidoma. In total, 4 months post-surgery, the patient remained tumor-free. PMID:26893698

    Acute renal failure (ARF) is a relatively frequent complication associated with heart transplantation. It develops in the first few days postoperatively and is characterized by oliguria with laboratory and urinary indices typical of pre-renal azotemia. Cyclosporine, especially with higher doses, is one of the many factors which play an integral part in the nephrotoxicity following cardiac transplant. Poor preoperative renal function and perioperative hemodynamic compromise may also contribute to ARF. The actual incidence of ARF now encountered by transplant centers may be lower than previously reported, the result of lower cyclosporine doses. Currently, management is entirely supportive, but novel therapeutic approaches with atrial natriuretic peptide-like substances are being explored. A case illustrating the typical clinical presentation of ARF after heart transplant will be presented and the clinical features will be reviewed. PMID:9381741

    A 58-year-old man was admitted to our hospital. Laboratory data showed severe liver injury and that the patient was positive for immunoglobulin M anti-hepatitis A virus (HAV) antibodies. He was also complicated with severe renal dysfunction and had an extremely high level of serum hepatocyte growth factor (HGF). Therefore, he was diagnosed with severe acute liver failure with acute renal failure (ARF) caused by HAV infection. Prognosis was expected to be poor because of complications by ARF and high serum HGF. However, liver and renal functions both improved rapidly without intensive treatment, and he was subsequently discharged from our hospital on the 21(st) hospital day. Although complication with ARF and high levels of serum HGF are both important factors predicting poor prognosis in acute liver failure patients, the present case achieved a favorable outcome. Endogenous HGF might play an important role as a regenerative effector in injured livers and kidneys.

    Elevated factor VIII level has recently been shown to be associated with increased risk of thrombosis. We report here a case of renal infarction in association with elevated factor VIII level. The patient presented with a three-day history of flank pain. Laboratory studies on presentation showed an elevated serum creatinine concentration and microscopic hematuria. He was found to have bilateral pulmonary emboli and left common femoral vein thrombosis; imaging studies showed evidence of renal arterial thrombosis with infarction. Hypercoagulability assessment showed an elevated factor VIII level. He was treated with heparin and warfarin with significant improvement in his renal function. Consideration should be given to measurement of factor VIII level as a part of the workup of unexplained thrombo-embolic events.

    Onyx is an emerging treatment modality for visceral vascular malformations, especially in cases in which delicate nidal penetration of the arteriovenous malformation (AVM) is desired. A computed tomography (CT) image presentation of hyperdense striations along the renal medulla secondary to the tantalum powder has not been previously reported. A 65-year-old woman presented to our institution with intermittent gross hematuria and left flank pain for 10 days. Both CT and conventional angiographies confirmed cirsoid-type renal AVM, which was successfully treated with Onyx. Follow-up CT after treatment revealed presence of hyperdense striations along the renal medulla, which resolved during later image follow-up. Despite its frequent usage in neural intervention, the application of Onyx in visceral AVM is gradually gaining interest, especially in cases in which delicate nidal penetration of the AVM is desired. Renal hyperdense striation sign should be recognized to avoid confusion with embolizer migration, and further studies in patients with renal function impairment may be helpful in understanding its influence of renal function.

    Onyx is an emerging treatment modality for visceral vascular malformations, especially in cases in which delicate nidal penetration of the arteriovenous malformation (AVM) is desired. A computed tomography (CT) image presentation of hyperdense striations along the renal medulla secondary to the tantalum powder has not been previously reported. A 65-year-old woman presented to our institution with intermittent gross hematuria and left flank pain for 10 days. Both CT and conventional angiographies confirmed cirsoid-type renal AVM, which was successfully treated with Onyx. Follow-up CT after treatment revealed presence of hyperdense striations along the renal medulla, which resolved during later image follow-up. Despite its frequent usage in neural intervention, the application of Onyx in visceral AVM is gradually gaining interest, especially in cases in which delicate nidal penetration of the AVM is desired. Renal hyperdense striation sign should be recognized to avoid confusion with embolizer migration, and further studies in patients with renal function impairment may be helpful in understanding its influence of renal function.

    Two studies in rhesus monkeys have shown that progesterone implants, Depo-Provera and Norplant, were associated with vaginal thinning. Progesterone implants have also been associated with an increased risk of simian immunodeficiency virus (SIV) acquisition. This study in 16 women was done to assess vaginal epithelial thickness and number of cell layers from biopsies taken in the untreated follicular and luteal phases, and at 1 month and 3 months after administration of Depo-Provera. There was no significant change over time in either parameter from biopsies obtained in the luteal phase compared with those at either time after Depo-Provera administration. There was also no change in the mean number of Langerhans cells in vaginal wall specimens and no change in cervical ectopy. It appears that women do not respond to exogenous progestins with the dramatic vaginal thinning seen in rhesus monkeys.

    We report a 15-year-old girl with features of the MURCS (Mullerian abnormalities, renal agenesis/ectopy and cervicothoracic somite dysplasia) association and birth defects not typically associated with MURCS. In addition to seizures and intellectual disability, she has cortical brain heterotopia, bilateral subclinical cataracts, submucous cleft palate and patent ductus arteriosus. We propose that this patient represents a more severe form of MURCS, or 'MURCS-plus', which may represent a defect of or insult to mesodermal morphogenesis. PMID:17786121

    Urolithiasis in children occurs with the incidence of 0.1-5%. Risk factors such as metabolic disorders, recurrent urinary tract infections and/or congenital abnormalities of urinary tract are detected in 75-85% of children with urolithiasis. Staghorn calculi is associated with delayed diagnosis and treatment of urinary tract infection caused by specific organisms, which produce the enzyme urease, promoting generation of ammonia and hydroxide from urea. We present two boys with staghorn calculi recognized in 8th and 31st month of age. The reason for performing ultrasonography was urinary tract infection in both boys. The younger child was previously healthy, with no symptoms of urolithiasis, the older one had recurrent urinary tract infections caused by Proteus mirabilis, episodes of anxiety and abdominal pain. Laboratory test and imaging studies excluded congenital abnormalities in the urinary tract and typical metabolic causes of urolithiasis in both boys. Treatment of infection-related stones in the younger child included two extracorporeal shock-wave lithotripsy (ESWL). In the older child, both ESWL and operation were performed. Staghorn calculi were composed of mixtures of magnesium ammonium phosphate (struvite) and calcium carbonate (apatite) and confirmed to be identified as infection-related stones. During follow-up in a nephrology outpatient clinic, values of blood pressure, renal ultrasonography, kidney function test were normal and no symptoms of urinary tract infections were clinically present. In patients with recurrent urinary tract infections, urolithiasis should be taken into consideration. The majority of staghorn calculi is often asymptomatic and can be diagnosed with an ultrasonography study performed routine or during urinary tract infection. PMID:27416622

We report a 77-year-old man, consulting in the emergency room for anuria that appeared 24 hours after a syncope. The patient was carrier of an inferior vena cava filter prophylactically installed 17 months earlier and was not receiving anticoagulation. Serum creatinine on admission was 5.45 mg/dl and blood urea nitrogen was 54 mg/dl. Computed tomography and Doppler ultrasonography showed an extensive thrombosis of inferior vena cava and both renal veins. Heparin therapy was started with a rapid recovery of renal function and diuresis.

    BACKGROUND Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil's disease. CASE REPORT A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient's condition drastically improved after initiation of doxycycline. On subsequent days, the patient's Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. CONCLUSIONS As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis presenting as Weil's disease is a common cause of renal and hyperbilirubinemia in endemic areas. Often, as was the case for our patient where the time from presentation to acute

    Common iliac artery stenosis after renal transplantation is a rare complication; it can occur in the course of hypertension and renal dysfunction. We report a case of suspected renal allograft rejection with iliac artery stenosis proximal to a transplanted kidney. A 52-year-old man with a history of cadaveric kidney transplantation 26 years previously underwent a second cadaveric kidney transplantation in the left iliac fossa because of graft failure 3 years before. In June 2012, the patient had progressive renal dysfunction. In July, a percutaneous needle biopsy was taken, and it showed no rejection; however, his renal function continued to get worse through September. A percutaneous allograft renal biopsy was performed under ultrasound guidance and showed hyperplasia of the juxtaglomerular apparatus and renin granules. Magnetic resonance angiography was used to evaluate the arteries in the pelvis and showed left common iliac artery stenosis, and a stent was placed. After percutaneous intervention, the patient's ankle brachial pressure index was within the normal range and the allograft function had improved. PMID:24656037

It is caused by renal cysts, benign and malignant renal tumors, vascular lesions, and antiplatelet or anticoagulant therapy. In this paper we report an unusual case of rupture of a renal cyst of a 66-year-old male patient during an aortic and iliac endovascular procedure for a massive calcified atheroma above the iliac bifurcation. We suspected that the bolus of high weight molecular heparin given during the procedure caused the rupture of the cyst. According to the literature, this is the first case of renal cyst rupture during an endovascular aortic procedure after administering a high weight molecular heparin bolus. PMID:27579210

Ingestion of large quantities can lead to methemoglobinemia, hemolytic anemia, jaundice, and acute renal failure. We report a case of a 78-year-old male with previously normal renal function who developed acute renal failure and jaundice without methemoglobinemia or hyperbilirubinemia after taking nearly 8 g of phenazopyridine over the course of 4 days. Initially presenting with oliguria, the urine output began to increase by day 2 of his admission, and the creatinine peaked 11 days after he began taking phenazopyridine, and he was discharged safely soon after. To our knowledge, this is the first such case of renal failure and jaundice without methemoglobinemia or hemolytic anemia in an adult patient with normal renal function.

Our purpose is to present the ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) findings in a case of left adrenal adenoma with a coincidental RLRV and to discuss the clinical importance of their imaging. Abdominal and scrotal US, abdominal CT and MRI were performed for a 50-year-old male patient who was referred with continuous abdominal pain, intractable hypertension, high levels of blood cortisol and proteinuria. On US, a hypoechoic solid mass measuring 4 × 3 cm in the left adrenal location and coincidental RLRV, besides multiple renal cysts, hepatomegaly, left-sided varicocele, and small-sized left testis were detected. CT and MRI also revealed the mass in the left adrenal gland which was consistent with adenoma. With CT and MRI, presence of RLRV was also verified.

    Tuberous sclerosis complex is a rare multisystemic genetic disorder associated with the development of benign hamartomas. Angiomyolipomas are one such characteristic finding that may be seen in 55–80% of tuberous sclerosis complex patients. While being normally asymptomatic, they can also cause significant morbidity and mortality. We present the case of a patient with tuberous sclerosis complex and recently discovered bilateral renal angiomyolipomas, admitted for hematuria who underwent left renal artery embolization; however, worsening renal function necessitated subsequent nephrectomy. Despite still being mainstays of treatment, invasive interventions are now being recommended for specific patient populations as demonstrated in our case. Emerging strategies targeting the PI3K/AKT/mTOR pathway have been shown to reduce the size of angiomyolipomas and are now used to treat asymptomatic cases >3 cm. Our review discusses these treatment options with the intention of increasing awareness of current recommendations and hopefully leading to increased application of these novel therapies that will reduce the need for invasive interventions.

    1990-05-01

    By means of TCM differentiation of symptom-complexes, the authors tested and analysed the urine osmotic pressure (UOP) and the urine and plasma osmotic ratio (UPOR) for 428 cases of renal disease, with the conclusion that the UOP and the UPOR were within the normal value range for not only the 36 cases lack of clinical symptoms so as to be unable to have TCM classification identified, but also for 24 cases of Wind edema excess syndrome mainly caused by pathogenic Wind's invasion to the Lung. But for 74 cases of damp-heat Kidney impairment and 294 cases with the main symptom being Kidney deficiency [including weakness of Qi of Kidney, Yang deficiency of Spleen and Kidney, Yin deficiency of Liver and Kidney], the value of their UOP and the UPOR had the tendency of reduction (P less than 0.01), among which the value of the patients of Kidney Yang deficiency reduced most obviously. The further observation showed that, for the nocturia patients caused by renal disease, the value of UOP and the UPOR reduced more obviously than usual. Therefore the authors assert that the test on UOP and UPOR will offer an objective index to patients' nocturia and Kidney-Qi weakness. 60 cases with renal disease of Kidney deficiency syndrome and 27 cases of damp-heat Kidney impairment syndrome under the diagnosis and treatment based on an overall analysis of symptoms and signs leads to the following conclusion: With the elimination of pathogenic factors and recovery of kidney, the damp-heat Kidney impairment patients' UOP will be increased. The low UOP of patients caused simply by Kidney deficiency, however, will recover slower.

    Portal vein thrombosis refers to an obstruction of blood flow in the portal vein; this rare disease can be both local and systemic. Local risk factors, accounting for about 70% of cases, can be abdominal cancers, inflammatory of infective diseases, surgical procedures or cirrhosis. A 62-year-old man, affected by hypertension and taking acetylsalicylic acid after a myocardial infarction in 1994, developed deep venous thrombosis on the right leg. Six months later the patient was admitted to the emergency unit due to abdominal pain. A CT scan revealed the presence of a complete splanchnic vein thrombosis and a primary tumor on the right kidney. The patient was treated with total parenteral nutrition and intravenous solution of heparin sodium first and then, because of occurrence of allergy, fondaparinux, with improvement of the abdominal pain. Subsequently he underwent right radical nephrectomy.

    Renal biopsy is an integral part of the nephrologists' diagnostic armamentarium. Usually it is performed by radiologists or nephrologists with radiologist's assistance. Our aim was to assess the efficacy and safety of percutaneous ultrasound-guided renal biopsy performed solely by nephrologists. We performed real-time ultrasound-guided renal biopsy on 37 patients (N group). The results were then compared with those of a similar number of biopsies done with radiologist's support (NR group) immediately prior to these. In the N group, 36 biopsies (97.3%) were successful and were histopathologically adequate, whereas in the NR group, all biopsies were successful but only 28 were adequate (75.68%). Eighteen patients required only a single attempt in the N group, whereas majority (34 patients) in the NR group required two or more attempts. The average attempt per bit of renal tissue was 1.22 in both the groups. The average number of passes per patient was 1.77 in the N group and 2.32 in the NR group. The mean size of renal tissue obtained was 1.41 ± 0.47 cm in the N group and 1.19 ± 0.42 cm in the NR group. The average number of glomeruli was 15.62 ± 5.26 and 13.7 ± 7.38 in the N and NR groups, respectively (P<0.05). In the N group, there were no complications except two cases of post procedural hematuria that was managed conservatively. There was no need for blood transfusion and both of them were discharged after 48 hours. No patient had peri-renal collection or hematoma on repeat ultrasonography of the abdomen at 24 hours. However, in the NR group, five patients developed complications and one patient required laparotomy. Our study shows that percutaneous ultrasound-guided renal biopsy can be safely and successfully performed entirely by nephrologists without outside assistance. In our series, nephrologists who performed solely took fewer attempts, had better yield and fewer complications when compared to biopsies performed with radiologist's assistance. More and

    Primary mucinous adenocarcinoma of the renal pelvis is easily misdiagnosed and it was rarely reported in the literature. We describe in this study a case of 40-year-old male patient presented with right lumbar pain of one year duration and elevated level of carcinoembryonic antigen (CEA). After a series of imaging examinations, the initial impression was a cystic renal cell carcinoma. Right radical nephrectomy was performed on the patient. The postoperative pathological examination indicated a primary mucinous adenocarcinoma of enteric type of the renal pelvis. After surgical removal of the tumor, an immunotherapy was administrated to prevent recurrence. The patient survives upon this report. A review of pertinent literature is also presented.

  15. Xp11.2 translocation renal cell carcinoma with egg-shell calcification mimicking a benign renal tumour: A case report

    The present study reports the case of a 20-year-old female who was identified to have a left renal angiomyolipoma (AML) with hemorrhage. Following temporary conservative observation, the patient received continuous ultrasonic follow-up. Due to the rapid growth of the lesion, further examinations were performed. Computed tomography (CT) plain scans revealed a partly high-density mass with marginal egg-shell calcification. Enhanced CT revealed a solid tumor with a rich blood supply. Since no fats were detected, the possibility of a typical AML was excluded, but the diagnoses of epithelioid AML or renal cancer were considered. Finally, the left kidney was partially excised laparoscopically. The intraoperative frozen section indicated a diagnosis of renal cell carcinoma (RCC). The left kidney was subsequently radically excised. Routine histopathological and immunohistochemical tests confirmed that the lesion was an RCC with an Xp11.2 translocation. The present study introduces the pitfalls in the diagnosis of Xp11.2 translocation RCC, which is a rare RCC subtype accompanied with uncommon imaging manifestations. The study suggests that when a rapidly-growing AML is detected by ultrasound, renal cancer with marginal calcification should be considered. Moreover, although egg-shell calcification mostly occurs in benign renal lesions, further examinations, such as enhanced CT, are recommended for identifying the nature of the masses and excluding the possibility of malignant tumors.

  16. Beethoven's renal disease based on his autopsy: a case of papillary necrosis.

    1993-06-01

    The autopsy report of Ludwig van Beethoven written by Dr Johann Wagner in 1827 reveals that he had renal calculi that had not been diagnosed during his lifetime, together with perirenal fibrosis. The most comprehensive interpretation of this autopsy finding is that the regular calcareous deposits in every one of his renal calices represented calcified necrotic papillae. Severe urinary obstruction or diabetes as possible causes of papillary necrosis were not present. Analgesic abuse because of headaches, back pain, and attacks of rheumatism or gout may be presumed on the basis of Beethoven's uncontrolled way of taking medication. Salicin, a commonly used analgesic substance of that time (dried and powdered willow bark), is able to cause papillary necrosis. Perirenal fibrosis may be due to chronic infection or drug intake. Beethoven's other well-known diseases are deafness caused by otosclerosis of the inner ear, relapsing attacks of diarrhea as the symptoms of irritable bowel syndrome, and liver cirrhosis following viral hepatitis and chronic alcohol consumption. Liver cirrhosis also may cause papillary necrosis. In Beethoven's case, renal papillary necrosis was most probably the consequence of analgesic abuse together with decompensated liver cirrhosis. The autopsy report of Beethoven is the first case of papillary necrosis recorded in the literature.

    An extremely rare adult example of renal carcinoma with t(6;11)(p21;q12 or q13) is presented here. The tumor of a 45-year-old Japanese male, excised under the diagnosis of renal cell carcinoma, was a well circumscribed 7 cm mass with light brown sectioned surfaces. Histologically, it was composed of a major population of large polygonal epithelioid cells in a nested alveolar growth and a subpopulation of smaller cells clustering around hyaline basement membrane material. The former cells possessed ample, clear to eosinophilic granular cytoplasm with well-defined cell borders and the latter was frequently accompanied by psammomatous calcification. These tumor cells exhibited immunoreactivity for melanoma markers, transcription factor EB and cathepsin K, but were not reactive for epithelial markers and transcription factor E3. While pulmonary metastatic foci that were noted preoperatively progressed rapidly following interferon-based therapy, subsequent sunitinib malate yielded a partial response and stabilized the lung metastasis for 6 months after surgery. We could trace 20 cases of 6p21 translocation renal carcinoma, among which only four were in individuals older than 40 years. Description of a new case like this is important since little is known about the prognosis and treatment of adult patients with this condition.

    Renal vein thrombosis (RVT) in neonates is a rare condition of low mortality but significant morbidity due to renal impairment.We report the case of a male term newborn with left RVT and elevated serum factor VIII (FVIII).The main symptoms of the patient and the important clinical findings: prompt diagnosis of RVT was possible because the classic clinical presentation of macroscopic hematuria, thrombocytopenia, and palpable flank mass were present in this newborn infant.The main diagnoses: finally, the reason of RVT was established when the infant was 3 months of age: the increased level of FVIII was confirmed. We discuss the diagnosis, therapy, and outcome of the patient and compare with the literature.Therapeutics interventions: however, despite anticoagulant therapy the left kidney developed areas of scarring and then atrophy.Conclusions and outcomes: Prothrombotic defects should be considered in all patients with perinatal RVT. Elevated factor VIII as a reason of RVT in neonatal period is particularly rare. Given a poor renal outcome in children associated with elevated levels of factor VIII, consideration could be given to more aggressive antithrombotic therapy in such cases.

    Renal dysfunction is increasingly recognized as a potential clinical feature of mitochondrial cytopathies such as mitochondrial encephalomyopathy, lacticacidosis and stroke-like episodes (MELAS) syndrome. Five cases of MELAS syndrome with renal involvement from 4 unrelated families are presented in this case series. Three of the 5 patients had a history of maternally-inherited diabetes and/or deafness. Focal and segmental glomerulosclerosis and arteriolar hyaline thickening were the most striking findings on renal biopsy. In addition to clinical presentation with the typical symptoms of MELAS syndrome, genetic testing in these patients identified the A3243G point mutation in the tRNALeu gene of the mitochondrial DNA (mtDNA). The diagnosis of MELAS syndrome was thus considered to be unequivocal. The incidence of kidney disease in MELAS syndrome may be underestimated although a study is required to investigate this hypothesis. As the A3243G mtDNA mutation leads to a progressive adult-onset form of focal segmental glomerulosclerosis (FSGS), screening for the MELAS A3243G mtDNA mutation should therefore be performed especially in patients with maternally-inherited diabetes or hearing loss presenting with FSGS.

    Cervical cancer is the most frequent type of cancer in women in many developing countries. Squamous cell carcinoma of the cervix spreads principally by lymphatics and less commonly through blood vessels. The most frequent sites for those who develop distant metastasis include lungs (21%), lumbar and thoracic spine (16%), and para-aortic lymph nodes (7%). Metastasis to the kidney is extremely rare with <10 previously reported cases. We report a case of renal metastasis from squamous cell carcinoma of the cervix detected in end-stage kidney due to hydronephrosis. PMID:27499599

    In the period January 1988-December 1995, a case-control study of diet and renal cell carcinoma (RCC) risk involving 121 cases and 243 hospitalized controls was carried out in Montevideo, Uruguay. After adjusting for major covariates, red meat intake was associated with a 3.4 increase in risk for the highest category of intake, with a significant dose-response pattern. Also, barbecued meat, protein and heterocyclic amine intakes were associated with significant increases in risk of RCC. The consumption of the beverage known as 'mate' (a ocal tea derived from the herb Ilex paraguariensis) was associated with an increased risk of 3.0 for heavy drinkers. PMID:9820187

    Tumor-to-tumor metastasis (TTM) is a rare phenomenon. We present a case of an invasive ductal carcinoma (IDC) of the breast metastasizing to a clear cell renal cell carcinoma (RCC). Breast cancer (BC) metastasis to the RCC is rarely reported, especially in resected kidney tumor. In several cases reported, IDC was the exclusively histologic type of BC metastasized to RCC. It seems that the different molecular type of IDC doesn't affect the metastatic tendencies to RCC. TTM was an indicator of diffuse disease. For any patient with a history of breast cancer, especially with multi-organs metastasis, resection of kidney tumor should be carefully considered.

    Squamous cell carcinoma of the renal pelvis is a rare neoplasm, often unsuspected clinically due to its rarity and ambiguous clinical and radiological features, and hence patients present at advanced stages resulting in poor prognosis. We report here four cases of incidentally diagnosed primary renal squamous cell carcinoma, treated at our hospital over a short span of one year, and review the relevant literature. Mean age of the patients (3 males, 1 female) was 60 years. All suffered from staghorn stones. Interestingly, renal carcinoma was unsuspected clinically in all patients. In one case, a computerised tomography scan showed a suspicious nodule. All underwent nephrectomy for nonfunctioning kidney. In just two cases, tumor was identified on gross examination, while the other two only showed thickened pelvis. Our series emphasises the need for pelvicalyceal biopsy during treatment for long-standing nephrolithiasis, and thorough sampling of the renal pelvis in nephrectomy specimen of such patients.

    Neonatal renal vein thrombosis is a rare condition. The present case is rather unfrequent and particularly educative since it shows the complete diagnostic triad including hematuria, flank mass and thrombocytopenia. The diagnosis relies on the demonstration, by Doppler ultrasound, of an obstructed renal venous bed. The investigation is completed by a platelet count and the determination of the prothrombin time, of the activated partial thromboplastin time as well as of the concentration of fibrinogen. The screening also includes the search for a possible etiology, such as a deficiency in coagulation proteins, the presence of antiphospholipid antibodies or of a genetic mutation of one of the coagulation factors. Since there exist no evidence based guidelines for the management of the disease, we will discuss the diagnosis and treatment in relation with the published literature.

    Emphysematous pyelonephritis (EPN) in renal allograft is rare but potentially lethal complication and requires aggressive medical and/or surgical therapy to achieve cure. We report a case of 60-year-old diabetic male with poor cardiac function on maintenance hemodialysis, who underwent delayed allograft nephrectomy for EPN in failed renal allograft. Blood culture grew Bacteroides. He was stable in the postoperative period but passed away on day 4 due to myocardial infarction likely secondary to poor baseline cardiac function. Delay in diagnosis and treatment could have contributed to this unfavorable outcome. There is a paucity of published literature regarding EPN in the transplant population, such that management decisions (percutaneous conservative versus urgent surgical) are challenging. Further studies are required to establish treatment guidelines.

    We report a rare case of primary renal allograft dysfunction due to myeloma cast nephropathy in a patient with no overt clinical features of multiple myeloma preceding his transplantation. A 45-year-old man on hemodialysis for six months for end-stage kidney disease due to presumed chronic glomerulonephritis developed immediate graft dysfunction post-transplantation. The graft biopsy was diagnostic of myeloma cast nephropathy. Other criteria for lambda light chain multiple myeloma were fulfilled with immunofixation electrophoresis and bone marrow biopsy. He was treated with plasmapheresis, bortezomib and high-dose dexamethasone. However, the patient succumbed to septicemia on the 37 th post-operative day. This is probably the first report of primary renal allograft dysfunction due to myeloma cast nephropathy diagnosed within the first week post-transplanation in a patient with unrecognized multiple myeloma.

    Renal cell carcinoma (RCC) metastatic to the head and neck region is quite rare. This report describes a case of RCC metastatic to the oral tongue presenting initially with a renal mass that evaded diagnosis by biopsy examination of the primary lesion and was eventually established as a papillary type RCC by lingual biopsy examination. The tongue mass progressed rapidly despite chemotherapy with interferon-α2b, caused difficulties with oral food intake, and thus necessitated removal by partial glossectomy. Treatment alternatives for lingual RCC metastasis include surgical resection for major functional impairment, risk of airway compromise, or massive hemorrhage. Radiotherapy might be useful and should be considered for specific patients. Lingual metastasis from RCC usually predicts poor survival.

    Malignant renal epithelioid angiomyolipoma (EAML) is rare, and currently there is no malignant criteria for its pathological diagnosis. In the present study, the case of a patient who suffered malignant renal EAML and underwent nephrectomy is reported. The histological patterns of the tumor were composed of sheets or nests of large polygonal epithelioid cells and thick-walled blood vessels, with clear mitoses. Immunohistochemistry demonstrated that the epithelioid and smooth muscle cells characteristically expressed human melanoma black-45, epithelial membrane antigen and actin. Pathological evaluation revealed malignant EAML with regional lymph node metastases. Magnetic resonance imaging and X-ray examination identified multiple liver and lung nodules at 16 months post-surgery. Since the patient did not respond to the initial treatment with doxorubicin and cisplatin, sorafenib was subsequently administered. However, the treatment was not effective, and the patient succumbed to multiple metastases six months later. PMID:26870174

    Fibromuscular dysplasia (FMD) is a well-known disease, but its diagnosis can be challenging. Typically, the symptomatic FMD are reported by young and middle aged people with high blood pressure refractory to medical treatment. We present a rare case of a young, healthy, and normotensive patient who presented with pain secondary to renal infarction, without any prior signs or symptoms or history of hypertension. This presentation of FMD has not been previously described. The typical but subtle angiographic findings of the macro-aneurysmal FMD as well as the successful endovascular treatment are discussed herein. The macro-aneurysmal form of FMD should be considered in the differential diagnosis of acute renal infarction in young and middle aged patients even if they do not have a history of hypertension.

    Patient: Male, 53 Final Diagnosis: Leptospirosis Symptoms: — Medication: — Clinical Procedure: None Specialty: Infectious Diseases Objective: Rare disease Background: Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil’s disease. Case Report: A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient’s condition drastically improved after initiation of doxycycline. On subsequent days, the patient’s Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. Conclusions: As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis

    Cholesterol crystal emboli (CCE) syndrome involving native kidneys is an underdiagnosed condition. CCE is rare in renal allografts. It may present with acute kidney injury, but usually not acute graft loss. CCE should be considered in patients with a history of atherosclerosis and an invasive arterial procedure who present with acute or chronic renal allograft dysfunction. Therapy for CCE is mainly supportive and carries a high rate of mortality. To the best of our knowledge, this is the first reported case of a patient who lost his native kidneys and renal allograft due to CCE arising from his own vasculature.

    Renal involvement is a significant complication of multicentric Castleman’s disease (MCD) and various glomerular involvements have been reported. A 56-year-old Chinese woman presented with proteinuria and skin rash, with lymphadenopathy and hypergammaglobulinemia. Lymph nodes and skin biopsy proven the case was multicentric CD with plasma cell pathological pattern. The renal biopsy was performed and six glomeruli were observed and two of these showed global sclerosis. Moderate increasing of mesangial matrix with mesangial cell proliferation were seen in every glomerulus. In addition, one-segmental sclerosis accompanied by adhesion of the Bowman’s capsule was revealed. Two of the glomeruli had crescents formation. Under immunofluorescence microscopy, immunofluorescence for anti-IgA, IgM, C3, C1q and FRA showed coarse and fine granular depositions along capillary walls and sparsely in the mesangium. Staining for anti-IgG was negative. Under electron microscopy revealed indiscriminate amyloidal deposits in glomerular basement membrane. The foot process of glomerular podocytes was fusion. Moderate increasing of mesangial matrix and mesangial cell proliferation were found. Subsequently, she was successfully treated with prednisone combined with cyclophosphamide therapy not only for proteinuria but also for renal function. PMID:25932265

    Inflammatory myofibroblastic tumor (IMT) is a rare type of mesenchymal tumor, which may affect various organs. The preferential site for IMT in the genitourinary system is the urinary bladder, while the presence of IMT in the kidney, and particularly in the renal pelvis, is rare. In the present report, the case of a 43-year-old man who was admitted to the Department of Urology of The Second Xiangya Hospital of Central South University (Changsha, China) in July 2012, with complaints of iterative gross hematuria and abdominal pain unresponsive to antibiotics is described. Computed tomography and magnetic resonance imaging indicated a slightly enhanced mass in the left renal pelvis of 1.5 cm in diameter. On request of the patient, a left nephrectomy was then performed, based on a suspected diagnosis of renal pelvic carcinoma. However, analysis of the intraoperative fast-frozen section exhibited proliferation of compact spindle cells, suggesting IMT. Therefore, further ureterectomy was avoided, and the patient remained in healthy condition thereafter. PMID:26788220

    Thrombo-embolism is one of the serious complications of takotsubo syndrome (TS). It typically occurs in the classical mid-apical left ventricular ballooning form of TS. This complication has not been reported in cases of left mid-ventricular ballooning type of TS. We describe a 67-year-old woman who presented with 2-3 days of increasing signs and symptoms of heart failure. Echocardiography showed marked hypokinesia/akinesia in the mid-anterior, mid-anterolateral, and mid-inferior wall of the left ventricle and mild hypokinesia in the apical region. There was also hypokinesia of the mid and apical parts of the right ventricle. One day after admission, she developed acute left-sided renal infarction. Left ventriculography and coronary angiography 3 days after admission showed typical left mid-ventricular ballooning with no identifiable coronary lesion. Follow-up echocardiography showed complete resolution of left and right ventricular dysfunction. Takotsubo syndrome with right ventricular involvement complicated with heart failure and left renal embolic infarction was diagnosed. The mechanism of left renal embolic infarction is discussed.

    We report a case of a 73-year-old male with heterochronous triple urogenital cancer. The patient was referred to our hospital because serum PSA was elevated (7.0 ng/ml) in 1998. Prostatic needle biopsy revealed prostatic cancer in the right lobe, and total prostatectomy was performed. The histopathological diagnosis was moderately differentiated adenocarcinoma (TlcNOMO). Non-muscle invasive bladder cancer (NMIBC) was detected during an examination for microhematuria in 2002. Transurethral resection of the bladder tumor (TURBT) procedure was performed, and the histopathological diagnosis was grade 2 urothelial carcinoma (pTa). A right renal mass was detected incidentally on follow-up CT for bladder cancer in 2008. Renal enucleation was performed in 2009. The histopathological diagnosis was grade 2 clear cell renal cell carcinoma (pTlaNXMO). NMIBC was detected on follow-up urethrocystoscopy in 2011. The TURBT procedure was performed, and the histopathological diagnosis was grade 2 urothelial carcinoma (pTa). On follow-up for urogenital cancer patients, it is important to investigate recurrence of the primary cancer and also heterochronous canceration of other urogenital organs.

    Renal transplantation usually is performed by placing the graft in the iliac fossa, anastomosing the renal vein to the iliac vein or, when this is not possible, to the vena cava. When vascular complications occur, particularly on the venous side, the position of the graft may have to be changed. This report describes orthotopic renal grafts and positioning of the organ with anastomosis to the splenic vessels. Venous drainage was established directly into the mesenteric-portal territory, with two cases to the portal vein and one to the inferior mesenteric vein. A new technique for the venous drainage of the renal graft is shown. We have used this model in two cases of infrarenal inferior vena cava thrombosis. The kidney was located in a retroperitoneal position, with venous drainage to the superior mesenteric vein through an orifice in the posterior peritoneum.

    We report a case of non-Hodgkin lymphoma (NHL) with acute renal failure. A 62-year-old man was admitted to our hospital on March 8, 2002 with leg edema and dyspnea on effort. About 3 weeks before admission, he was found to have slightly high serum creatinine (Cr) and high lactate dehydrogenase (LDH) levels by another home doctor. Physical examination revealed anemic conjunctivae and leg edema, but the urinary volume was preserved. Blood examination showed high BUN (64 mg/dl) and Cr levels (3.91 mg/dl). Urinary analysis showed proteinuria (1.05 g/day) and high BMG (14,434/microg/day) and NAG (4.55 U/day) levels, suggesting severe tubulointerstitial injury. On ultrasonography of the kidney, the bilateral kidneys showed marked swelling without hydronephrosis. To investigate the genesis of renal failure, we performed a renal biopsy. The specimen showed normal glomeruli, but a large number of cells infiltrated in the tubulointerstitial area with normal tubulointerstitial structure. The cells stained positively with anti-leukocyte antigen and L26 (B cell marker), and negatively with cytokeratin and UCHL-1 (T cell marker). These findings indicate that the interstitial cells were non-Hodgkin lymphoma with B cell diffuse large cells. Chemotherapy was performed with VAD (vincristine sulfate, doxorubicin hydrochloride, dexamethasone) considering his renal dysfunction. To avoid tumor lysis syndrome after chemotherapy, hemodialysis was performed on days 1-4 after the initiation of chemotherapy. After a series of chemotherapy, the urinary volume increased and serum Cr levels decreased to 2 mg/dl. After additional therapy with 4 courses of CHOP, he improved and was discharged on day 180 after admission.

    Tumor thrombus from renal cell carcinoma is commonly reported in renal vein and inferior vena cava with a few reports of gonadal vein involvement. Here, we report a case of an elderly female who underwent fluorodeoxyglucose (FDG) positron emission tomography-computed tomography scan for initial staging of left renal cell carcinoma. Along with an FDG avid left renal mass lesion, scan also revealed FDG avid tumor thrombus in the entire length of the left gonadal vein.

    We describe a nematode larva in a subcutaneous nodule excised from a 44-year-old Chinese male who had been living in Japan for 15 years. Morphological features suggested that the worm was a dioctophimatid nematode. PCR amplification and sequencing of small subunit ribosomal DNA and mitochondrial cytochrome subunit c oxidase genes allowed us to identify the larva as the giant kidney worm, Dioctophyme renale (Goeze, 1972). This is the first molecularly confirmed human case of a dermal D. renale infection.

    Introduction Herein we present a rare case of pontaneous rupture of a giant renal angiomyolipoma (AML), with symptoms of hypovolemic shock (Wunderlich’s syndrome), which was managed by urgent total nephrectomy. Presentation of case A 53 year old female was transferred to the emergency room with progressive acute painful swelling of the left lateral abdominal area, duration of 5 h. An emergent ultrasonic examination, revealed a heterogeneous—solid mass with maximum diameter of 23 cm, with probable origin from the left kidney. Due to worsening of the clinical status (hypovolemic shock), loss of consciousness and acute drop of haematocrit level to 17.8%, the patient was urgently intubated in the emergency room and transferred to the operating theater. A giant haemorrhagic mass was found originating from the left kidney, which removed en-block with the left kidney. The patient was transferred to the intensive care unit. Her recovery was uneventful. The histopathologic examination revealed a giant renal angiomyolipoma (25 × 18 × 8 cm) with extensive bleeding. Discussion Enlarged renal AMLs can rupture. This can be sudden and painful with manifestations of hypovolemic shock. The management of AMLs has been correlated with symptoms. Patients with life-threatening retroperitoneal haemorrhage, require urgent exploration as retroperitoneal bleeding can lead to severe complications, increasing morbidity. Conclusion In case of giant angiomyolipoma with intratumoral haemorrhage, and symptoms of Wunderlich’s syndrome, partial or total nephrectomy is a good treatment option in order to save the patient’s life.

    Xp11 translocation renal cell carcinoma (RCC) is a relatively rare tumor mainly affecting children and adolescents. It shows significant morphological overlap with the 2 most common adult renal tumors, which are the clear cell (conventional) RCC and papillary RCC. We describe case of a young adult female who presented with right flank pain and abdominal mass. Radiological investigations showed features suggestive of renal cell carcinoma in the right kidney. Histopathological findings while suggestive of Xp11 carcinoma, showed significant overlap with the recently described entity clear cell papillary RCC. TFE3 immunohistochemistry confirmed the tumor to be Xp11 translocation RCC. The patient had an aggressive course with lymph node metastasis. In this report, we discuss differential diagnosis and the diagnostic challenges of Xp11 translocation RCC in adults.

    Abstract Rhodococcus equi is an unusual cause of infection in humans, but has emerged as an opportunistic pathogen among immunocompromised patients. Primary pulmonary involvement is the most common clinical presentation, although the spectrum of disease is broad. Diagnosing R. equi infections remains challenging, both from clinical and microbiological view, and no standard treatment has been established. In this report, we present a detailed case of a 57-year-old male renal transplant recipient who developed R. equi bacteremia with a concomitant Pneumocystis jirovecii pneumonia. We describe the clinical features of R. equi infections, highlight the importance of an early diagnosis, and briefly review treatment options for this rare infection. PMID:27500216

    Chronic renal failure results in reduced elimination of a variety of substances within the blood, including numerous drugs and their metabolites. This report describes a case of a man who died in jail, after less than 48 hours of being incarcerated, wherein postmortem toxicology testing revealed a blood benzoylecgonine level of 0.25 mg/L with no cocaine detected, suggesting possible recent cocaine use in jail. Autopsy and investigation revealed severe underlying cardiovascular disease and dialysis-dependent CRF, thus accounting for the elevated benzoylecgonine levels and allaying concerns that the man obtained and used cocaine in jail.

    Transformation of the urothelium to the intestinal type of epithelium is rare in the pelvis with very few cases reported in the literature. The present study reports extensive intestinal metaplasia of the pelvi-calyceal system without residual urothelium in a 35-years-old woman with a 2 years history of renal calculi. Right - sided Nephrectomy was undertaken. Immunohistochemistry of the metaplastic epithelium revealed positive expression of CK20, low Ki-67 index and negative expression of p53. In this patient long standing metaplastic changes did not progress to adenocarcinoma which indicates that extensive intestinal metaplasia is not always associated with malignancy. PMID:26549072

    It has been hypothesized that chronic renal failure (CRF) predisposes patients to infection with intestinal protozoa. We tested this hypothesis with a matched case-control study to determine the prevalence of these protozoa and their diarrhea associated symptoms among 50 patients with CRF (cases) from Taif, western Saudi Arabia. Fifty diarrheal patients without CRF were recruited in the study as controls. Participants were interviewed by a structured questionnaire and stool samples were collected. Samples were thoroughly examined with microscopy and three coproantigens detection kits. Enteric protozoa were detected in 21 cases and 14 controls. Blastocystis spp. were the most predominant parasite (16% in cases versus 8% in controls), followed by Giardia duodenalis (10% in cases versus 12% in controls) and Cryptosporidium spp. (10% in cases versus 6% in controls). Cyclospora cayetanensis was identified in two cases, while Entamoeba histolytica was described in one case and one control. Intestinal parasitism was positively associated with the male gender, urban residence, and travel history. Clinical symptoms of nausea/vomiting and abdominal pain were significantly varied between the parasitized cases and controls (P value ≤ 0.05). Given the results, we recommend screening all diarrheal feces for intestinal protozoa in the study's population, particularly those with CRF. PMID:26491455

    We herein report the case of a 74 year-old woman with a diffuse large B-cell lymphoma and bilateral renal masses identified on computed tomography scans during the initial staging process. Following partial bilateral nephrectomy, histopathological examination revealed renal cell carcinoma (RCC) and oncocytoma in the left and the right kidneys, respectively. Shortly afterwards, lymphoma of the left palatine tonsil was diagnosed and the patient received chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP regimen), followed by radiotherapy. Due to metastasis of the RCC to the right breast, pancreas and the area of the left psoas major muscle, systemic treatment with pazopanib was commenced. To the best of our knowledge, this is the first reported case of simultaneous diagnosis of non-Hodgkin lymphoma (NHL), RCC and oncocytoma. The aim of this study was to review the related literature, discuss issues regarding the management of this unusual case and identify possible common etiopathological mechanisms underlying the simultaneous occurrence of NHL, RCC and oncocytoma.

An unusual cause of massive gross hematuria and an even rarer cause of hemodynamically significant anemia, its presentation remains variable from incidental imaging findings to severe hypertension and congestive heart failure. Case presentation We present a case of a 44-year-old Chinese man with no personal or familial history of bleeding diasthesis that presented with gross hematuria leading to clot retention after routine physical activity. Conclusions We have presented this case in an effort to highlight the possibility of this entity as a cause of acute upper urinary tract hemorrhage and the need for a computed tomography angiogram to clinch the diagnosis.

    Legionella pneumophyla is the agent responsible of Legionnaire's disease. It appears as a severe pneumonia and often requires admission in Intensive Care Unit. In literature, renal failure is reported to occur in 15 percent of Legionnaire disease and this event induce a mortality over 50% of these cases. The authors describe a case of Legionnaire's pneumonia with respiratory failure, rhabdomyolysis and acute renal failure. Patient was a female, 61 yrs old, admitted to our hospital because of fever (38 degrees-38.5 degrees C), severe respiratory failure (pH = 7.49, PaCO2 = 23.1 mmHg, PaO2 = 56.7 mmHg), oliguria (< 200 ml/24 h); chest x-rays and computed tomography (TC) showed a pneumonia at right lower lobe. Among other things, in blood analysis was noted the following values: BUN = 47 mg/dl, creatinine = 2.1 mg/dl, Na+ = 133 mmol/L, Cl- = 97 mmol/L, Ca+ = 7.2 mg/dl, K+ = 5.8 mmol/L, AST = 213 U/L, ALT = 45 U/L, LDH = 1817 U/L, CPK = 16738 U/L, CPK-MB = 229 U/L, myoglobin > 4300 ng/ml., leucocyte count = 17,500/mmc (N = 92%, L = 3%, M = 5%), positive anti Legionella IgG and IgM (IgG > 1:64, IgM > 1:96), evidence of Legionella soluble antigen in the urine analysis. Therapy with clarytromicyne (500 mg b.i.d i.v.) and rifampicin (600 mg/die i.v.) was begun; computed tomography showed after six days an improvement of pulmonary lesion but, in the following days, health status and blood analysis got worse. Patient went on antibiotics and underwent haemotherapy (Hb: 8 gr/dl), haemodialysis because of acute renal failure but healthy status worse furthermore and she died on 18th days after admission. This case point out rhabdomyolysis with acute renal failure is suggestive for Legionnaire's disease and is associated with high rate of mortality.

  15. A rare case of cytomegalovirus, scedosporium apiospermum and mycobacterium tuberculosis in a renal transplant recipient

    PubMed Central

    2014-01-01

    Background Renal transplant recipients are at high risk of developing multiple infections, often concomitantly because of their immunocompromised status. Post renal transplant infections are often elusive and require extensive evaluation for proper diagnosis and treatment. A high index of suspicion is required and an attempt should be made to confirm the microbiological diagnosis from each site involved to rule out multiple infections. Case presentation We report a 50-year-old female, a renal allograft recipient who presented with left hemiplegia, esophageal ulcers and fever 3 months after her transplant. Esophageal biopsy revealed Cytomegalovirus (CMV) inclusions and the whole blood quantitative CMV polymerase chain reaction (PCR) was positive. Neuroimaging showed a brain abscess, stereotactic biopsy from which revealed Scedosporium apiospermum on fungal culture. Her tacrolimus and mycophenolate were stopped and she was managed with intravenous ganciclovir and voriconazole. With these measures, she showed marked improvement in her general and neurological condition. Two months later, she developed recurrence of fever with dry cough. Radiological investigation revealed a cavitating lung lesion, a needle aspiration from which demonstrated acid-fast bacilli. She was started on antituberculous treatment. With these measures, she recovered completely and maintained good graft function despite being on only prednisolone 10 mg once a day. Conclusion Although CMV disease is not uncommon in the first three months post transplant, Scedosporium is a rare cause of brain abscess. On the other hand, tuberculosis is common in transplant recipients, especially in developing countries, like India. However, this is the first case report of occurrence of these three infections in the same patient, demonstrating the importance of a good microbiological work-up from each site involved in immunosuppressed subjects.

    We present herein the cases of two patients who developed idiopathic portal hypertension (IPH) following renal transplantation. Both patients had been treated with azathioprine and prednisolone for 6 years and 4 months and for 4 years and 7 months, respectively, and presented with splenomegaly and thrombocytopenia suggesting hypersplenism. Celiac angiography showed a dilated splenic artery and vein in both patients. When the splenic artery was obliterated with a balloon catheter in case 1, the portal venous pressure decreased from 51 cmH2O to 36 cmH2O, and the direction of the superiomesenteric venous blood flow became hepatopetal rather than hepatofugal. These results suggested that the spleen might have played an important role in the development of IPH in these two patients. A splenectomy was therefore performed, immediately following which the portal venous pressure decreased remarkably, and the esophageal varices disappeared during the postoperative follow-up period. Microscopic examination of liver biopsies taken at the operation revealed lymphoplasmacytic infiltration with bile duct hyperplasia but no evidence of periportal fibrosis, and electron microscopy demonstrated very mild perisinusoidal fibrosis. Thus, the histological changes seen in the livers of these patients seemed not to have caused the portal hypertension. In conclusion, although few patients develop IPH after renal transplantation, we should be aware of its possibility and consider splenectomy as the treatment of choice.

    In the United States during the year 2015, approximately 61,560 patients are expected to be diagnosed with kidney cancer and 14,080 to die from the disease. We present the case of a patient with renal cell carcinoma who suffered severe perioperative bleeding and coagulopathy after emergency sternotomy. We also engage in relevant aspects of perioperative anesthesia care including the considerations and management of coagulopathy, liver failure and renal failure in the oncologic patient. The case is a 49-year-old man with vena cava tumor thrombus who underwent radiologic tumor embolization, left radical nephrectomy, and inferior vena cava (IVC) thrombectomy. Postoperatively, he developed sepsis, multiple organ failure, and a pericardial effusion requiring pericardiocentesis. During pericardiocentesis, he suffered an iatrogenic left entricular perforation, requiring an emergency sternotomy and left ventricular repair. Cancer patients are often challenging for surgical and anesthesia teams, emergency care requires an organized and comprehensive approach. The use of recombinant factor VIIa NovoSeven can help in managing severe postoperative bleeding after cardiothoracic surgery in oncologic patients, but further studies should be done to confirm this.

    A morphologic study of biopsy specimens from 16 cases of membranous nephropathy in the cat (11 cases) and dog (five cases) was carried out using conventional light microscopy, immunofluorescence, transmission electron microscopy, and scanning electron microscopy. Depending on the degree of membranous change of the capillary loops and glomerular scarring, each case was graded "mild," "moderately severe," or "advanced." Clinically, most cases were presented showing the nephrotic syndrome, although two cases were presented in chronic renal failure. Most cases were followed through to necropsy after an interval ranging between 2 days and 3 years. In some cases, repeated biopsies were taken during this period. PMID:7024632

    The relationships between ambient PM2.5 and PM10 and arrhythmia and the effect modification by cigarette smoking were investigated. Data from EPA air quality monitors and an established national-scale, log-normal kriging method were used to spatially estimate daily mean concentrations of PM at addresses of 57,422 individuals from 59 examination sites in 24 US states in 1999-2004. The acute and subacute exposures were estimated as mean, geocoded address-specific PM concentrations on the day of, 0-2 days before, and averaged over 30 days before the ECG (Lag0; Lag1; Lag2; Lag1-30). At the time of standard 12-lead resting ECG, the mean age (SD) of participants was 67.5 (6.9) years (84% non-Hispanic White; 6% current smoker; 15% with coronary heart disease; 5% with ectopy). After the identification of significant effect modifiers, two-stage random-effects models were used to calculate center-pooled odds ratios and 95% confidence intervals (OR, 95% CI) of arrhythmia per 10 μg/m3 increase in PM concentrations. Among current smokers, Lag0 and Lag1 PM concentrations were significantly associated ventricular ectopy (VE) - the OR (95% CI) for VE among current smokers was 2 (1.32-3.3) and 1.32 (1.07-1.65) at Lag1 PM2.5 and PM10, respectively. The interactions between current smoking and acute exposures (Lag0; Lag1; Lag2) were significant in relationship to VE. Acute exposures were not significantly associated with supraventricular ectopy (SVE), or with VE among non-smokers. Subacute (Lag1-30) exposures were not significantly associated with arrhythmia. Acute PM2.5 and PM10 exposure is directly associated with the odds of VE among smokers, suggesting that they are more vulnerable to the arrhythmogenic effects of PM. PMID:18979352

    Renal artery dissection may be caused by iatrogenic injury, trauma, underlying arterial diseases such as fibromuscular disease, atherosclerotic disease, or connective tissue disease. Radiological imaging may be helpful in detecting renal artery pathology, such as renal artery dissection. For patients with acute, isolated renal artery dissection, surgical treatment, endovascular management, or medical treatment have been considered effective measures to preserve renal function. We report a case of renal infarction that came about as a consequence of renal artery dissection.

    Mucin and mucin-like material are features of mucinous tubular and spindle renal cell carcinoma (MTS RCC) but are rarely seen in papillary renal cell carcinoma (PRCC). We reviewed 1311 PRCC and identified 7 tumors containing extracellular and/or intracellular mucinous/mucin-like material (labeled as PRCCM). We analyzed these using morphological, histochemical, immunohistochemical, and molecular genetic methods (arrayCGH, FISH). Clinical data were available for six of the seven patients (five males and one female, age range 61-78 years). Follow-up was available for four patients (2-4 years); one patient died of widespread metastases. Tumor size ranged from 3 to 5 cm (mean 3.8). Of all cases, histological architecture showed a predominantly papillary pattern. Mucin or mucin-like was extracellular in one, intracellular in three, and both intra/extracellular in three cases. All tumors were positive for AMACR, vimentin, and OSCAR, while CK7 was positive in four. Mucicarmine stain was positive in all cases, PAS in six and Alcian blue in three cases. Five tumors were positive for MUC 1, but none were positive for MUC 2, MUC 4, or MUC 6. In only four cases, genetic analysis could be performed. Gain of chromosomes 7 and 17 was found in two cases; gain of 17 only was found in one case. Loss of heterozygosity of 3p was found in one case together with polysomy of chromosomes 7 and 17. No abnormalities of VHL, fumarate dehydrogenase, and TFE3 genes were detected. We conclude that PRCCM is a rare but challenging subtype of RCC that deserves to be further studied. In all the tumors, the mucin-like material was found in those stained with mucicarmin, but other conventional and immunohistochemical stains did not reveal consistent features of a single mucin. The molecular-genetic profile of these tumors was most consistent with that of typical papillary RCC, although one case had mixed genetic features of papillary and clear RCC. PRCCM has metastatic potential, as evidenced by

    A case report is presented of a young man admitted to a general hospital with leukocytosis, elevated temperature, right lower lobe infiltrate, and confusion. A diagnosis of rhabdomyolysis, acute renal failure, and Legionnaire's disease was made. The patient subsequently had a respiratory arrest and died on the 29th hospital day. This triad is currently an enigma in the field of internal medicine. The diagnosis of each entity is elusive, and in many cases must be made by the astute clinician. Diagnostic features along with early intervention measures and their expected outcomes are discussed. Recognition of the interrelationship of these diseases, risk factors, and vague clinical presentations might allow further prospective intervention methods and diagnostic procedures to be undertaken to avoid the fatal consequences seen in this disease triad.

    Systemic sclerosis (SSc) is a chronic multisystem autoimmune disorder characterised by progressive functional and structural abnormalities in blood vessels leading to microvascular dysfunction, excessive production and deposition of collagen leading to the fibrosis of skin and internal organs. The aetiology of the disease is unknown. However, exposure to various environmental factors, such as polyvinyl chloride and silica have been thought to play a role in the development of the disease. For this reason, silicone breast implants have been postulated as a cause for a range of autoimmune diseases including systemic sclerosis. This remains as yet unconfirmed. We report the case of a 52-year-old woman who presented with rapid development of skin thickening followed by scleroderma renal crisis (SRC) following rupture of silicone breast implants. This is the first published case of SRC in this setting. The literature on silicone and autoimmunity is reviewed. PMID:24480575

    Abstract De-novo malignancy is a serious posttransplant complication. While the incidence of Kaposi sarcoma (KS) is low, the time for its diagnosis is early after renal transplantation. Typically, it can be identified because of the classical skin lesion. We herein report an unusual case of rapid progressive KS without skin lesions in a 52-year-old patient leading to death within 8 months after kidney transplantation. This striking case illustrates the usefulness of [18F]2-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography for demonstrating the cause of unexplained deterioration of patient’s condition. Early identification of KS is critical because early (modification of) therapy can substantially improve patient’s prognosis. PMID:25192485

    Renal cell carcinoma (RCC) may metastasize to mediastinal lymph nodes without any abdominal lymph node involvement. The present study describes an autopsy-proven case of RCC presenting with a large mediastinal mass; the case had been previously misdiagnosed as small cell lung carcinoma due to imaging analysis results, an elevated serum level of neuron-specific enolase and the presence of small atypical cells with a high nuclear/cytoplasmic ratio. Despite RCC occurrence being rare, it should be considered in the differential diagnosis, particularly when a mass located in the kidneys presents with metastases to the mediastinal lymph nodes, even if there is no involvement of the abdominal lymph nodes and the primary lesion is of a small size.

    Serum creatinine is commonly used as a marker of renal function, but increases in serum creatinine might not represent changes in glomerular filtration rate (GFR). INCB039110 (2-(3-(4-(7H-pyrrolo[2,3-day]pyrimidin-4-yl)-1H-pyrazol-1-yl)-1-(1-(3-fluoro-2-(trifluoromethyl)isonicotinoyl)piperidin-4-yl)azetidin-3-yl)acetonitrile) is an inhibitor of the Janus kinases (JAKs) with selectivity for JAK1. In a phase 1 study, a modest and reversible increase in serum creatinine was observed after treatment with INCB039110. However, a dedicated renal function study with INCB039110, assessed by iohexol plasma clearance, conducted in healthy volunteers indicated no change in GFR. In vitro studies were therefore conducted to investigate the interaction of INCB039110 with five transporters that are likely involved in the renal clearance of creatinine. Cell systems expressing individual or multiple transporters were used, including a novel quintuple-transporter model OAT2/OCT2/OCT3/MATE1/MATE2-K. INCB039110 potently inhibited OCT2-mediated uptake of creatinine as well as MATE1-/MATE2-K-mediated efflux of creatinine. Given the interactions of INCB039110 with multiple transporters affecting creatinine uptake and efflux, an integrated system expressing all five transporters was sought; in that system, INCB039110 caused a dose-dependent decrease in transcellular transport of creatinine with weaker net inhibition compared with the effects on individual transporters. In summary, a molecular mechanism for the increase in serum creatinine by INCB039110 has been established. These studies also underline the limitations of using serum creatinine as a marker of renal function. PMID:25605813

Normally, the relative renal function estimated by the two methods correlates well with each other. We here present two patients with renal tubular acidosis who showed impaired/altered DMSA uptake with normal EC renal dynamic study depicting the pitfall of DMSA imaging in tubular disorders. The two presented cases also depict distinct pattern of Tc-99m DMSA scintigraphic findings in patients with proximal and distal renal tubular acidosis, thus highlighting the factors affecting DMSA kinetics.

    Delusional infestation is an aspecific psychiatric condition manifested either as a primary psychotic disorder or a secondary disorder induced by a wide range of very different medical conditions. Both primary and secondary delusional infestations seem to respond to typical and atypical antipsychotics. The latter are considered the first-line treatment although the use of second-generation antipsychotics featuring a higher metabolic, cardiovascular, and renal tolerability is preferable in secondary cases, which often occur in patients with multiple, severe medical conditions. We report a case of a 72-year-old patient affected by delusional infestation associated with severe renal failure, metabolic syndrome, hypertensive cardiopathy, and chronic cerebrovascular disease.

    Carcinoid tumors are well documented in the pulmonary and gastrointestinal systems, but very rare in the urinary tract, especially in the renal pelvis. We report on a 60-year-old female patient who presented with left flank pain and fever. Abdominal computed tomography demonstrated a heterogeneously enhancing mass in the left renal pelvis and a stone at the left proximal ureter. Multiple parenchymal lesions were also observed, which were identified as uneven caliectasis displaying air-fluid levels and renal parenchymal atrophy. The patient underwent simple nephro-ureterectomy. Macroscopically, a polypoid mass was observed in the renal pelvis. Microscopically, the tumor revealed acinar, tubular, and solid pattern and was composed of small, monotonous and hyperchromatic cells. Lining epithelia in renal pelvis and ureter revealed columnar epithelia with dysplastic change. The tumor cells were positive for chromogranin A, synaptophysin, CD56, and focally positive for cytokeratin. Immunohistochemical staining of synaptophysin and chromogranin A highlighted the neuroendocrine cells in the columnar epithelium. Ki-67 (1:50; MIB-1) labeling index was less than 1% in the area with highest uptake. We report here a case of carcinoid tumor of the renal pelvis that was associated with adjacent dysplastic columnar epithelium. PMID:26644387

    Renal vein thrombosis is a complication of the nephrotic syndrome presumably related to compression of renal veins by edematous parenchyma and a concomitant hypercoagulable state. The diagnosis has been made by demonstrating marked widening of the left renal vein as it crosses horizontally anterior to the aorta on computed tomography. Inferior venacavography confirmed the presence of thrombosis within the vessels. CT is suggested as a method for noninvasive imaging of the renal veins which might eliminate the need for venography.

    Bilateral renal cell carcinomas (RCCs) pose a challenge for clinical treatment and management. Most bilateral RCCs are sporadic, and do not show a hereditary pattern indicative of VHL syndrome or other inherited cancers. The origin and evolution of these sporadic bilateral RCCs remains elusive. We obtained normal and tumor samples from two male patients suffering from early stage synchronous bilateral clear cell RCC (ccRCC), and analyzed genomic DNA using whole exome sequencing and bisulfite pyrosequencing. We detected distinct 3p loss of heterozygosity (LOH) in both tumors in each patient. Two tumors within the same patient harbored distinct driver mutations and different CpG hypermethylation sites in the VHL promoter. Moreover, tumors exhibit independent evolutionary trajectories. Therefore, distinct 3p LOH, combined with contingent driver gene mutations and independent VHL hypermethylation, led to independent tumor origin and parallel evolution of bilateral ccRCC in these two patients. Our results indicate that tumors in these two cases were not due to common germline oncogenic mutations. They were results of multiple de novo mutations in each kidney, rather than primary ccRCC with contralateral renal metastasis. Therefore, histopathologic and genetic profiling from single tumor specimen may underestimate the mutational burden and somatic heterogeneity of bilateral ccRCCs. PMID:27383411

    Xp11.2 translocation/transcription factor enhancer 3 (TFE3) fusion gene associated with renal cell carcinoma (Xp11.2 translocation RCC) is rare and occurs predominantly in children and adolescents. The current study reports the case of a 14-year-old male with Xp11.2 translocation RCC, who presented with chest pain that had persisted for 1 month. A solid neoplasm was located in the left kidney of the patient. Contrast-enhanced computed tomography revealed the presence of a solid mass in the kidney, with uneven enhancement. Destruction of multiple bones was also observed. The patient was treated with a radical nephrectomy. The pathological examination of the tumor revealed that the tumor cells contained an eosinophilic cytoplasm in the renal interstitial tissue. Immunohistochemistry revealed that the tumor cells expressed P504S, cluster of differentiation 10, pan-cytokeratin, vimentin and TFE3. In conclusion, Xp11.2 translocation RCC is a rare type of kidney cancer. Diagnosing this disease prior to surgery is challenging, and providing a definite diagnosis requires histopathological and immunohistochemical examination, while genetic analysis may also be required.

    The effect of diuretics on residual renal function expressed as residual GFR (rGFR) and urine volume (rUV) using 24-hour urine collections has not been well examined in hemodialysis (HD) patients. We present a small (seven patient) but provocative case series describing a strikingly low rate of decline in rUV and rGFR (average of creatinine and urea clearances, 24-hour urine collections) in patients treated with increasing doses of furosemide (up to 360 mg/day) during the first 2 years after initiation of HD. Between 6 and 12 months, the mean rUV fell by 1 ml/month, whereas rGFR declined by 0.03 ml/min/1.73 m(2) /month. The mean rate of decline from 12 to 24 months for rUV (33 ml/month) and rGFR (0.02 ml/min/1.73 m(2) /month) were also low. While data are clearly limited and the observation retrospective, they are consistent with the better documented benefit of diuretics observed in end-stage renal disease patients treated with peritoneal dialysis.

    Metastatic pancreatic cancer is rare, accounting for approximately 2% of all pancreatic malignancies, and most cases arise from renal cell carcinoma. We report the case of a 63-year-old woman, who presented with a pancreatic tumor detected during her annual health examination. She had undergone left nephrectomy 13 years previously for renal cell carcinoma. Computed tomography (CT) revealed two tumors in the head and body of the pancreas, a hypervascular tumor and a hypovascular tumor with an enhanced rim, respectively. She underwent pylorus-preserving pancreaticoduodenectomy, and metastatic pancreatic tumors arising from the kidney with clustered clear cell carcinoma immunohistochemically positive for CD10 were diagnosed. This report presents the different enhancement features of different lesions on CT scans. Because the enhancement features of lesions have been reported to vary according to the size of the metastatic tumor, a knowledge of the history of renal cell carcinoma is crucial for diagnosis.

    Sorafenib is a tyrosine kinase inhibitor (TKI) of the vascular endothelial growth factor receptor (VEGFR) used for advanced renal cell carcinoma. Treatment with sorafenib prolongs progression-free survival in patients with advanced clear-cell renal cell carcinoma. However, in spite of its therapeutic efficacy, sorafenib causes a wide range of adverse events. Cardiovascular adverse events have been observed when sorafenib was used with targeted agents. Although these adverse events like hypertension, reduced left ventricular ejection fraction, cardiac ischemia or infarction were manageable with standard medical therapies in most cases, some had a poor clinical outcome. We report three cases of acute myocardial infarction associated with sorafenib in patients with metastatic renal cell carcinoma. PMID:26497860

Our patient is a 31-year-old woman referred for left flank pain and gross hematuria who was noted on imaging to have a 6.5 cm left renal pelvis stone containing gas. Cultures revealed Escherichia coli from the urine and stone material. Chemistry revealed underlying gouty diathesis. The stone was removed using robotic extended pyelolithotomy. Overall, renal function remained unchanged while drainage improved on nucleotide renography. Review of the world literature suggests that gas-containing renal stones are invariably associated with emphysematous pyelonephritis commonly caused by E. coli and Klebsiella. Contributing factors to gas-containing stone formation include urinary stasis, metabolic mineral derangement and, in a minority of the cases, diabetes. PMID:23798875

    Introduction and Aims. Congenital absence of the vas deferens is an uncommon anomaly and this clinical condition is responsible for up to 1-2% of male infertility. It can be either unilateral or bilateral and the associated anomalies include cryptorchidism, seminal vesicles and ejaculatory ducts anomalies, and renal anomalies such as renal agenesis. We hereby present a case of congenital unilateral absence of vas deferens, which was found incidentally during an evaluation of undescended testis in a patient with ipsilateral renal agenesis. Case Presentation. A 10-month-old boy was referred to the urology clinic with an undescended right testis. Preoperative abdominal ultrasonography showed agenesis of the right kidney and the absence of right vas deferens and epididymis was confirmed during laparoscopic orchiectomy performed due to short right spermatic cord. There were no other concomitant anomalies of the genitourinary system observed in evaluation. Conclusion. Congenital unilateral absence of the vas deferens with cryptorchidism and renal agenesis is a rare diagnostic entity. Cryptorchidism or absent vas deferens found incidentally should lead the physician to evaluate the status of the contralateral vas deferens and conduct a renal tract ultrasound study. PMID:27597925

    Four feline renal cell carcinomas (RCCs) were examined using histopathological and immunohistochemical procedures. Specimens were classified by predominant histological pattern according to WHO criteria. A panel of antibodies including β-catenin, C-KIT, VEGF and VEGF-R2 and double immunostaining for vimentin/cytokeratin and for E-cadherin/CD10 was selected to characterize the tumors. Neoplasms were classified as tubular (3/4) and papillary (1/4). Neoplastic epithelial cells were cytokeratin, vimentin, E-cadherin, VEGF-R2 positive and C-KIT negative; 3 cases were β-catenin positive, whereas only 2 tumors were CD10 and VEGF positive. No correlation with histotype was evident. Our results confirm the low frequency of RCCs in cats and suggest a histological pattern similar to canine RCCs. In contrast, a peculiar immunohistochemical profile different from both canine and human RCCs is identified. PMID:26888581

    Exact prediction of Hemorrhagic fever with renal syndrome (HFRS) epidemics must improve to establish effective preventive measures in China. A Seasonal Autoregressive Integrated Moving Average (SARIMA) model was applied to establish a highly predictive model of HFRS. Meteorological factors were considered external variables through a cross correlation analysis. Then, these factors were included in the SARIMA model to determine if they could improve the predictive ability of HFRS epidemics in the region. The optimal univariate SARIMA model was identified as (0,0,2)(1,1,1)12. The R2 of the prediction of HFRS cases from January 2014 to December 2014 was 0.857, and the Root mean square error (RMSE) was 2.708. However, the inclusion of meteorological variables as external regressors did not significantly improve the SARIMA model. This result is likely because seasonal variations in meteorological variables were included in the seasonal characteristics of the HFRS itself. PMID:27706256

    Mucormycosis is a rare infection caused by the ubiquitous filamentous fungi of the order Mucorales and class Zygomycetes. These species are vasotropic, causing rapid onset of tissue infarctions and necrosis and subsequent thrombosis by invading vascular bed. The disease spectrum ranges from involvement of skin, sinuses, lung, and brain to disseminated and mostly fatal infections, especially in immunocompromised hosts. Here, we present a case of a fatal disseminated mucormycosis in a 56-year-old female who had deceased donor renal allograft transplantation ~2 weeks prior to presentation. She presented with shortness of breath and dry cough. Despite being on broad-spectrum antibiotics/antifungals and proper management by transplant, infectious disease, and primary team, she died within 3 weeks of admission. Autopsy showed disseminated mucormycosis of lungs and thyroid. Disseminated infection within 2 weeks of solid organ transplantation in this patient was one of the rare features of mucormycosis.

    Hepatobiliary cystadenomas are mucinous cystic neoplasms arising in the liver, extrahepatic bile ducts or gall bladder. Extrahepatic cystadenomas are rare neoplasms requiring complete excision as there is a chance for recurrence and malignant transformation. Angiomyolipoma (AML) belongs to the perivascular epithelioid cell group of neoplasms, and kidney is the commonest site involved. We report a case of an unusual combination of extrahepatic biliary cystadenoma with angiomyolipoma in an adult female without evidence of tuberous sclerosis. The patient presented with abdominal discomfort and on ultrasonological examination showed a cyst close to liver suggestive of hydatid disease and an incidental mass in kidney which was diagnosed as angiomyolipoma. Histopathological examination revealed biliary cystadenoma of liver and renal angiomyolipoma. Clinical and radiological evaluation did not show any manifestations of tuberous sclerosis. Such an unusual incidence of two separate neoplasms in a patient without syndromic association was not obtained even after extensive literature search. PMID:27437238

A diagnosis of a metastatic tumor to the mandible from the right kidney was made after evaluation by computed tomography and bone scan with Tc99 methyl diphosphonate which also revealed multiple bone metastases. Histologically diagnosis was clear cell variant of RCC. Patient has been put on radiotherapy for symptomatic treatment and a molecularly targeted drug. The therapy effectively stopped the progressive growth of oral and other metastatic lesions. The quality of life is relatively well maintained with tolerable adverse effects. The patient is still on our follow-up with an improved quality of life. PMID:27563625

    Hepatobiliary cystadenomas are mucinous cystic neoplasms arising in the liver, extrahepatic bile ducts or gall bladder. Extrahepatic cystadenomas are rare neoplasms requiring complete excision as there is a chance for recurrence and malignant transformation. Angiomyolipoma (AML) belongs to the perivascular epithelioid cell group of neoplasms, and kidney is the commonest site involved. We report a case of an unusual combination of extrahepatic biliary cystadenoma with angiomyolipoma in an adult female without evidence of tuberous sclerosis. The patient presented with abdominal discomfort and on ultrasonological examination showed a cyst close to liver suggestive of hydatid disease and an incidental mass in kidney which was diagnosed as angiomyolipoma. Histopathological examination revealed biliary cystadenoma of liver and renal angiomyolipoma. Clinical and radiological evaluation did not show any manifestations of tuberous sclerosis. Such an unusual incidence of two separate neoplasms in a patient without syndromic association was not obtained even after extensive literature search.

    Four feline renal cell carcinomas (RCCs) were examined using histopathological and immunohistochemical procedures. Specimens were classified by predominant histological pattern according to WHO criteria. A panel of antibodies including β-catenin, C-KIT, VEGF and VEGF-R2 and double immunostaining for vimentin/cytokeratin and for E-cadherin/CD10 was selected to characterize the tumors. Neoplasms were classified as tubular (3/4) and papillary (1/4). Neoplastic epithelial cells were cytokeratin, vimentin, E-cadherin, VEGF-R2 positive and C-KIT negative; 3 cases were β-catenin positive, whereas only 2 tumors were CD10 and VEGF positive. No correlation with histotype was evident. Our results confirm the low frequency of RCCs in cats and suggest a histological pattern similar to canine RCCs. In contrast, a peculiar immunohistochemical profile different from both canine and human RCCs is identified. PMID:26888581

    We report 3 cases of primary renal cell tumor simulating atrophic kidney with distinct gross, morphologic, immunohistochemical, and molecular genetic features. The tumors were retrieved out of more than 17 000 renal tumors from the Plzen Tumor Registry. Tissues for light microscopy had been fixed, embedded, and stained with hematoxylin and eosin using routine procedures. The tumors were further analyzed using immunohistochemistry, array comparative genomic hybridization, and human androgen receptor. Analyses of VHL gene and loss of heterozygosity (LOH) 3p were also performed. The patients were 2 women and 1 man, with ages ranging from 29 to 35 years (mean, 31.3 years). Grossly, the neoplasms were encapsulated and round with largest diameter of 3.5 cm (mean, 3.2 cm). Follow-up available for all patients ranged from 2 to 14 years (mean, 8 years). No aggressive behavior was noted. Histologically, akin to atrophic (postpyelonephritic) kidney parenchyma, the tumors were composed of follicles of varying sizes that were filled by eosinophilic secretion. Rare areas contained collapsed follicles. Each follicle was endowed with a small capillary. The stroma was loose, inconspicuous, and focally fibrotic. Two types of calcifications were noted: typical psammoma bodies and amorphous dark-blue stained calcified deposits. Immunohistochemically, tumors were strongly positive for cytokeratins (OSCAR), CD10, and vimentin, with weak immunopositivity for CAM5.2 and AE1-AE3. WT1 and cathepsin K were weakly to moderately focally to diffusely positive. Tumors were negative for cytokeratin 20, carbonic anhydrase IX, parvalbumin, HMB45, TTF1, TFE3, chromogranin A, thyroglobulin, PAX8, and ALK. Only 1 case was suitable for molecular genetic analyses. No mutations were found in the VHL gene; no methylation of VHL promoter was noted. No numerical aberrations were found by array comparative genomic hybridization analysis.

    Renal cell carcinomas (RCCs) have a strong tendency to metastasize, and the most common sites are the lungs, bones and liver. Late recurrence is another feature of the RCC, with lesions appearing ≥10 years after surgical treatment. However, fibrosis has rarely been associated with the disease. The present study reports a case of recurrent RCC that manifested as a fibrotic mass within the thorax. A 48-year-old man presented with dyspnea that had persisted for 3 days. The patient had undergone a right radical nephrectomy for stage II clear cell carcinoma of the kidney 6 years previously. The patient was a current smoker, with a smoking history of 20 pack-years. Chest radiography showed pleural effusion in the right thorax with an egg-sized mass shadow within the right upper lung (RUL) field. Computed tomography (CT) showed a main mass, 7 cm in diameter, within the RUL, with heterogeneous enhancement and multiple nodules of various sizes in the lungs, suggestive of primary lung cancer or metastatic RCC. A CT-guided percutaneous needle aspiration biopsy was obtained from the main mass, but histology revealed dense fibrous tissue without any malignant cells. Positron emission tomography-CT demonstrated an irregular hypermetabolic RUL mass, with a standardized uptake value (SUV) of 5.0, along the right pleura, and small pulmonary nodules (SUV, 2.0). Ultrasound-guided biopsy was attempted for a smaller hypermetabolic pleural nodule and the result was clear cell adenocarcinoma, consistent with the previous renal histology. The present study describes the case, along with a review of the relevant literature. PMID:27313703

    Succinate dehydrogenase (SDH), which is located on the mitochondrial inner membrane, is essential to the Krebs cycle. Mutations of the SDH gene are associated with many tumors, such as renal cell carcinoma, wild type gastrointestinal stromal tumors (WT GISTs) and hereditary paragangliomas/pheochromocytomas. Herein we present a rare case diagnosed as a WT GIST complicated with a renal chromophobe cell tumor and detected a novel germline heterozygous mutation (c.2T>C: p.M1T) in the initiation codon of the SDHA gene. We also conduct a preliminary exploration for the mechanism of reduced expression of SDHB without mutation of SDHB gene. Our case enriches the mutation spectrum of the SDH gene. After reviewing previous studies, we found it to be the first case diagnosed as a WT GIST complicated with a synchronous renal chromophobe cell tumor and identified a novel germline heterozygous mutation. It was also the second reported case of a renal cell carcinoma associated with an SDHA mutation. PMID:26722403

    Agenesis of the inferior vena cava, especially of the infrarenal segment, is exceptional. This condition is thought to result from thrombosis during gestation rather than from a true congenital malformation. Agenesis of the inferior vena cava can be associated with renal vein thrombosis, which in turn is related to suprarenal hemorrhage in the fetus. We present a case of agenesis of the inferior vena cava with preservation of the hepatic segment, thrombosis of the left renal vein, and secondary bilateral suprarenal hemorrhage diagnosed prenatally using sonography and magnetic resonance imaging.

    Secondary causes of minimal change disease (MCD) account for a minority of cases compared to its primary or idiopathic form and provide ground for consideration of common mechanisms of pathogenesis. In this paper we report a case of a 27-year-old Latina woman, a renal transplant recipient with systemic lupus erythematosus (SLE), who developed nephrotic range proteinuria 6 months after transplantation. The patient had recurrent acute renal failure and multiple biopsies were consistent with MCD. However, she lacked any other features of the typical nephrotic syndrome. An angiogram revealed a right external iliac vein stenosis in the region of renal vein anastomosis, which when restored resulted in normalization of creatinine and relief from proteinuria. We report a rare case of MCD developing secondary to iliac vein stenosis in a renal transplant recipient with SLE. Additionally we suggest that, in the event of biopsy-proven MCD presenting as an atypical nephrotic syndrome, alternative or secondary, potentially reversible, causes should be considered and explored.

    There is a widening gap between the needs and possibilities of kidney transplantation. In order to solve the problem of organ shortage, the selection criteria for kidney donors have been less stringent over the last years. Favorable outcome of renal transplantation from deceased donors with acute renal failure requiring dialysis may have an important role in expanding the pool of donors. We present the case of two renal transplantations from a polytraumatized 20-years old donor with acute renal failure requiring dialysis. One recipient established good diuresis from the first post-transplant day and did not require hemodialysis. The second recipient had delayed graft function and was treated with 8 hemodialysis sessions. The patient was discharged with good diuresis and normal serum creatinine. After two years of follow-up, both recipients have normal graft function. According to our experience, kidneys from deceased young donors with acute renal failure requiring dialysis may be transplanted, in order to decrease the number of patients on transplantation waiting lists.

    BACKGROUND--The organisation, management, outcome and cost of follow up of a large group of mainly immunocompromised patients and healthcare workers who were exposed to a staff member of a London renal unit with smear positive pulmonary tuberculosis are described. METHODS--Following British Thoracic Society (BTS) guidelines, 576 close contacts were identified and divided into three groups: (1) 303 renal patients including 61 with renal transplants; (2) 90 surgical patients; and (3) 183 staff members. Screened contacts were interviewed, completed a symptoms questionnaire, and were offered a chest radiograph and Heaf or Mantoux test if appropriate with referral to a chest physician if required. RESULTS--Overall, 524 (85%) living contacts have been screened: 243 (97%) renal (first screening), 63 (70%) surgical, and 135 (74%) staff contacts. Thirty one transplant patients were prescribed isoniazid chemoprophylaxis. Fifty two renal patients had died before screening and 11 deaths occurred after first interview. One case of tuberculosis epidemiologically related to the index case was diagnosed on clinical criteria. A review of the case records and/or death certificates and entries on to tuberculosis registers indicated no further cases. The cost of the investigation was estimated to be approximately franc25 000, or franc44 per contact screened, with staff costs comprising 79% of the total. CONCLUSIONS--Undiagnosed tuberculosis in healthcare workers working with immunosuppressed patients can lead to large and expensive follow up studies. The applicability of the 1990 and 1994 BTS guidelines to the investigation of tuberculosis in an immunocompromised nosocomial group, and the role of the infection control doctor and the consultant in Communicable Disease Control in overlapping nosocomial and community incidents, are discussed.

    The historic, physical, laboratory, and histologic findings for 74 cats with chronic renal disease were reviewed. Most cats were older, and no breed or sex predilection was detected. This most common clinical signs detected by owners were lethargy, anorexia, and weight loss. Dehydration and emaciation were common physical examination findings. Common laboratory findings were nonregenerative anemia, lymphopenia, azotemia, hypercholesterolemia, metabolic acidosis, hyperphosphatemia, and isosthenuria. The most common morphologic diagnosis was chronic tubulointerstitial nephritis of unknown cause. The other pathologic diagnoses were renal lymphosarcoma, renal amyloidosis, chronic pyelonephritis, chronic glomerulonephritis, polycystic renal disease, and pyogranulomatous nephritis secondary to feline infectious peritonitis.

    Benign renal lesions, apart from simple cysts, are rarely sampled by fine-needle aspiration biopsy (FNAB) and are potential diagnostic pitfalls. A complex renal mass in a 33-yr-old pregnant woman, presenting in the second trimester with haematuria, was aspirated twice, a week apart, under ultrasound guidance. The second FNAB yielded predominantly mesenchymal elements thought to represent an angiomyolipoma, but the mass was identified as a multilocular renal cyst (MLRC) on the nephrectomy specimen. Differential diagnoses of angiomyolipoma, MLRC, and renal cell carcinoma (RCC) are compared and discussed in relation to patient management.

    The typical symptoms of advanced cancer of the stomach are well known in clinical practice. The presented case concerns a patient with symptoms of left-sided renal colic, caused by a malignant tumour involving the ureter, which was diagnosed with a CT scan. The multifocal process, involving the stomach, two parts of the colon, the left ovary and the side of the pelvis, was confirmed only during surgery. The resection or partial resection of the above-mentioned organs involved by the malignant process and reconstruction of the alimentary tract as well as the ureter were performed at time of this operation. The patient's recovery was without any complications. The histopathological findings support the diagnosis of this malignant process as disseminated stomach cancer. In the available literature only two cases of stomach cancer metastasis to the ureter have been described. In both cited examples resection of the ureter with nephrectomy was performed. The review of the literature supports the value of stomach palliative resection in prolonging life and improving quality of life. PMID:23788876

    Tumor-to-tumor metastasis is an uncommon but well-documented phenomenon. We present a case of a clear cell renal cell carcinoma (RCC) metastasizing to an invasive ductal carcinoma (IDC) of the breast. A 74-year-old woman with a past history of clear cell RCC status after radical nephrectomy underwent right modified radical mastectomy for an enlarging breast mass 3 years after nephrectomy. Histological examination revealed a small focus with distinct morphological features similar to clear cell RCC encased in the otherwise typical IDC. Immunohistochemical studies showed that this focus was positive for CD10 and vimentin, in contrast to the surrounding IDC, which was negative for both markers and positive for Her2/neu. Based on the histological and immunohistochemical features, the patient was diagnosed with metastasis of clear cell RCC to the breast IDC. To the best of our knowledge, this is the first reported case of a breast neoplasm as the recipient tumor in tumor-to-tumor metastasis. PMID:24530247

    We herein report an unusual case of a low-grade myxoid renal epithelial neoplasm, with peculiar and previously unreported morphologic and immunohistochemical features. The lesion was characterized by noninfiltrative borders, myxoid stroma and elongated tubular and cordlike epithelial structures. These were lined by 2 different epithelial cell types, flat and elongated basal cells and cuboidal to spindle shaped eosinophilic luminal cells, with low-grade nuclear features and a few small nucleoli. The lesion morphologically resembled a pleomorphic adenoma of the salivary gland. The immunohistochemical profile interestingly confirmed the myoepithelial differentiation of the basal epithelial layer, as demonstrated by the coexpression of several myoepithelial markers such as p63, caldesmon, calponin, smooth muscle actin, and S-100, together with epithelial markers such as low and high-molecular weight cytokeratins. The tumor proved benign at follow-up. A definitive classification and histogenetic interpretation of this previously unreported tumor type awaits description of further cases showing similar features which, perhaps, as it may happen, went so far unnoticed.

    Renal infarction (RI) is frequently misdiagnosed or diagnosed late because of its rarity and nonspecific clinical presentation, which may result in irreversible damage to the renal parenchyma or increase the risk of other embolic events affecting additional organs. Multiple causal mechanisms and cases of idiopathic RI have been reported, but the causal factors are not clear in most cases.Here, we report the case of a patient with heterochronic bilateral RI caused by thrombophilia. Although he had several risk factors for hypercoagulation disorders, two gene mutations-MTHFR 677 C>T and PLG 1858G>A-were identified by genome sequencing of the entire exome. The findings suggest the possibility of a synergistic relationship between the two gene mutations.Thus, screening for gene mutations may provide additional clues for clarifying the cause of RI and thrombophilia.

    Renal actinomycosis is a rare infection caused by fungi of the genus Actinomyces. A 74-year-old male was admitted to our hospital because of gross hematuria with urinary symptoms and intermittent chills. Computed tomography of the abdomen showed thrombosis in the left renal vein and diffuse, heterogeneous enlargement of the left kidney. After nephrectomy, sulfur granules with chronic suppurative inflammation were seen microscopically, and the histopathological diagnosis was renal actinomycosis. Our case is the first report of renal actinomycosis with renal vein thrombosis.

    INTRODUCTION Metastases to the breast from extra-mammary tumors are uncommon and few sporadic cases are reported in the international literature. An accurate differential diagnosis of secondary cancer is mandatory because both prognosis and treatment differ with respect to primary breast tumors. PRESENTATION OF CASE We present the case of a 70-year-old woman with an isolated metastasis to the breast occuring 9 years after undergoing a nephrectomy for Renal Cell Carcinoma (RCC). Clinical examination revealed a palpable and mobile mass in the right breast with an enlarged ipsilateral axillary lymph node. Mammographic findings showed a dense, well circumscribed solid mass and the breast ultrasonography findings were those of a hypoechoic homogeneous solid nodule with no posterior attenuation but with prominent peripheral vascularity. A tru-cut biopsy was conclusive for a metastatic deposit by RCC. A whole-body CT scan showed no evidence of further recurrences. The patient underwent metastasectomy and exeresis of the papable lymphnode. DISCUSSION In patients with former surgery for RCC, a diagnosis based on a preoperative biopsy allows to indicate the proper surgical treatment: in facts, as compared to primary breast tumors treatment, the rationale to pursue wide surgical margins is pointless in cases of metastases and, similarly, the biopsy of the sentinel lymphnode is void of sense due to the lack of its physiopathological prerequisite. CONCLUSION We suggest to consider a micro-histological biopsy of any new breast lesion appearing in a patient with a history of treatment for RCC. Prompt diagnosis is necessary to choose the right treatment. PMID:24632302

    Renal artery embolism (RAE) is an uncommon entity that is most often secondary to a cardiac source. Most reported cases have been in patients with underlying atrial fibrillation (AF), and occurrence of RAE, especially in patients with valvular heart disease, and sinus rhythm is very rare. We describe an unusual case of a young female who presented with sudden onset right flank pain, vomiting, anorexia, and hematuria, and was found to have thrombotic occlusion of the distal right renal artery. Although she denied any previous cardiac history, detailed cardiovascular examination revealed the presence of severe rheumatic mitral stenosis without any evidence of AF or left atrial clot. She was initially managed conservatively using low molecular weight heparin followed by oral anticoagulation with resolution of symptoms. A successful balloon mitral valvotomy was performed six weeks later. The patient is asymptomatic at her last follow-up of six months with preserved renal function. In symptomatic patients, clinicians need to consider the possibility of RAE even in patients of valvular heart disease with underlying sinus rhythm. Appropriate management of the underlying cardiac condition is imperative since embolism may be recurrent leading to compromise of renal function, if left untreated. PMID:26997399

    This case report illustrates the dynamic and static renal scintigraphic images of a patient with an unusual large diverticulum of the renal pelvis. The initial diagnosis by intravenous pyelography (IVP) and ultrasonographic (US) examination was a renal pelvic diverticulum of the left kidney, and the patient was referred to the nuclear medicine department for exploration of the effect of the pelvic diverticulum on renal functions. We performed dynamic renal scintigraphy with technetium-99m (Tc-99m) labeled mercaptoacetyl triglycine (MAG-3) and static renal scintigraphy with Tc-99m labeled dimercaptosuccinic acid (DMSA). In dynamic renal scintigraphy, bilaterally normal concentration function was observed. While right kidney excretion function was normal, an incomplete excretion pattern was seen on the left side. Complete urinary flow obstruction occurred approximately at the 10th minute of the acquisition, which did not seem to respond to the i.v. furosemide application. However, when only the renal cortex was included in the region of interest, the obstructive pattern disappeared. In static renal scintigraphy, a large renal pelvic diverticulum localized antero-medially was clearly visualized in the left-anterior oblique projection, most probably due to accumulation of radiopharmaceutical inside it. This case showed that a renal pelvic diverticulum should be thought of when an incomplete excretion pattern is seen on dynamic renal scintigraphy. Using only a cortical region of interest may also help to distinguish other types of obstructive pattern from diverticulum. Additionally, Tc-99m DMSA scintigraphy may show diverticulum localization with antero-oblique projections in addition to routine projections.

    Renal cell carcinoma (RCC) linked to germline mutation of succinate dehydrogenase subunits A, B, C, and D (SDHA, SDHB, SDHC, and SDHD, respectively) has been recently included as a provisional entity in the 2013 International Society of Urological Pathology Vancouver classification. Most SDH-deficient tumors show SDHB mutation, with only a small number of RCC with SDHC or SDHD having been reported to date. Only one case of SDH-deficient renal carcinoma known to be SDHA mutated has been previously reported. Here we report an additional RCC harboring an SDHA mutation occurring in a 62-year-old man with right flank pain and nodal metastasis. The tumor was characterized by an infiltrative pattern with solid, acinar, and papillary components. Loss of SDHA and SDHB protein by immunohistochemistry confirmed the diagnosis. Hybrid capture-based comprehensive genomic profiling identified 3 genomic alterations in tumor tissue: (i) a novel single-nucleotide splice site deletion in SDHA gene, (ii) single-nucleotide deletion in NF2 gene, and (iii) EGFR gene amplification of 19 copies. This is the second report of SDHA-mutated RCC. With increased awareness, this rare tumor can be recognized on the basis of distinctive morphology and confirmation by immunohistochemistry and genomic profiling. PMID:26476567

    A case is presented of minimum renal trauma, leading to a retroperitoneal hematoma as a consequence of a simple renal cyst rupture as well as an artery contained therein. The etiopathogenicity of this phenomenon is commented. The different clinical manifestations of renal trauma are highlighted, as well as the suspicion of previous renal pathology when a large renal lesion is found secondary to minimum renal trauma. The approach of the renal pediculum must be the first step in the surgical treatment of renal trauma.

    Only 2 previous studies, conducted in Australia, United States and northern Europe, considered the role of dietary fibre intake on renal cell carcinoma (RCC) risk, and both showed a modest, inverse association. Therefore, we investigated in depth the topic of fibres and RCC, using data from a multicenter case-control study conducted in Italy from 1992 to 2004, including 767 cases with incident, histologically confirmed RCC and 1,534 controls admitted to the same network of hospitals as cases with acute nonmalignant conditions. Multivariate odds ratios (OR) and 95% confidence intervals (CI) were obtained after allowance for major identified confounding factors, including total energy intake. The continuous OR for an increase in intake equal to the difference between the 80th and the 20th percentile were 0.94 (95% CI: 0.82-1.08) for total dietary fibre, 0.98 (95% CI: 0.85-1.13) for soluble noncellulose polysaccharides, 0.92 (95% CI: 0.80-1.05) for total insoluble fibre, 0.90 (95% CI: 0.78-1.04) for cellulose, 0.95 (95% CI: 0.84-1.06) for insoluble noncellulose polysaccharides and 1.06 (95% CI: 0.93-1.21) for lignin. With reference to the sources of fibre, we found an inverse association with vegetable fibre (OR = 0.84, 95% CI: 0.73-0.97), but no association with fruit (OR = 0.98, 95% CI: 0.86-1.12) and grain fibre (OR = 1.05, 95% CI: 0.95-1.15). The inverse association with vegetable fibre may reflect a real favorable effect, or be an indicator of a beneficial role of a diet rich in vegetable on RCC risk. PMID:17582601

    Epidemiological evidence of a relationship between vitamin D and kidney cancer risk has been inconsistent despite experimental data indicating that vitamin D and its metabolites may inhibit carcinogenesis. Previously we reported an inverse association between renal cell carcinoma (RCC) risk and occupational ultraviolet (UV) exposure among European men. In this study, we examined the association between occupational UV exposure and RCC risk among US residents and investigated whether this association varied by race and sex. Lifetime occupational data for 1,217 RCC cases and 1,235 controls in a population-based case-control study, conducted from 2002 to 2007, were assessed for occupational UV exposure. We evaluated exposure metrics in quartiles based on control exposure levels and calculated associations between RCC risk and occupational UV exposure using unconditional logistic regression adjusted for sex, race, body mass index, smoking, hypertension, center, education, family history of cancer and dietary vitamin D intake. A general pattern of decreasing RCC risk with increasing UV exposure was observed. Cases had significantly lower cumulative occupational UV exposure than controls (fourth quartile vs. first: odds ratio = 0.74 [95% confidence interval = 0.56-0.99], p-trend = 0.03). Similar results were observed for other UV exposure metrics. The association with occupational UV exposure was stronger for women than for men, but did not differ by race. Our findings suggest an inverse association between occupational UV exposure and RCC, particularly among women. Given the sex finding discrepancies in this study versus our previous study, additional research is need to clarify whether the protective effects of occupational UV exposure and RCC risk are real.

    Metastatic tumors involving salivary glands arising from the non-head and neck area are very rare. Renal cell carcinoma (RCC) is known for its high propensity for metastasis to unusual localizations. RCC metastasis to the maxillofacial area is an uncommon event (16%), but metastasis to salivary glands is extremely rare. We report a series of 9 such cases retrieved from two institutions. The group included 6 females and 3 males. The age at diagnosis ranged from 60 to 97 years (mean 72.6 years). The tumors involved the parotid gland in 7 cases, and the submandibular and small salivary gland of the oral cavity in 1 case each. The size of tumors ranged from 0.4 to 5 cm. Total parotidectomy with selective neck dissection was performed in 4 cases, while superficial parotidectomy was performed in 1 case and simple resection in 3 cases. Histologically, all the tumors were clear cell renal cell carcinomas, and therefore the differential diagnosis mainly included clear cell variants of salivary gland carcinomas. The parotid gland was the initial manifestation of renal malignancy in 4 of the cases, while in the remaining 5 cases a history of RCC had been known. The salivary gland involvement developed from 11 months to 13 years after the time of diagnosis of the primary tumor. In 2 cases it was the first site of dissemination. Pathologists need to maintain a high index of suspicion for the possibility of metastasis when confronted with oncocytic or clear cell neoplasms developing in salivary glands. RCC, although rare, should be included in this differential diagnosis. PMID:27179273

    Donation after circulatory death (DCD) supplies a big percentage of the organ source pool. Compared to living-related donations, donor kidneys from DCD are commonly with lower quality since they inevitably suffer from hypoxia, hypotension, and inadequate organ perfusion during the progression to circulatory arrest. The current case presents a 44-year-old male donor with wide range subarachnoid hemorrhage and multiple skull fracture from a car accident. Multiple stones were detected in his right kidney. We performed a modified ex vivo pyelolithotomy and ureteroscopy on the bench to render a stone-free allograft. We also improved the donor kidney with hypothermic/perfusion preservation machine before renal transplantation. The recipient showed no complications during the first two-month post-operational follow-up. Such a donor kidney with stones may probably be discarded by conventional perspective. Yet, the combination of the ex vivo bench-surgery technique and hypothermic oxygenation/perfusion makes it a qualified donor kidney. Thus we have demonstrated a promising way of saving borderline qualified DCD donor kidneys. PMID:26885172

    Mucinous tubular and spindle cell carcinoma of the kidney (MTSCC-K) is an unusual renal tumor. It is important to increase the recognition of the clinicopathological features of MTSCC-K and improve its clinical and differential diagnosis. This report described four cases of MTSCC-K with clinical, imaging, and pathological examination and showed that the tumor boundaries of MTSCC-K were clear, and tumor cells arranged into tubules and cord-like beams, between which was lightly stained myxoid stroma. The tumor cells were smaller and cube- or oval-shaped, with single small eosinophilic nucleoli, low-grade nuclei, and little nuclear fission. The myxoid stroma was scattered around lymphocytes and plasma cells. Immunohistochemical markers including CK7, CD117, EMA (epithelial membrane antigen), vimentin, and CK8/18, showed positive expression in tumor cells, but the tumor cells were negative for CD10 and villin. The proliferation index of Ki-67 was 5-10%. Since MTSCC-K is a rare low-grade malignancy, with unique histological and immunohistochemical characteristics, it is important for clinicians and pathologists to have a defined awareness of this tumor type in order to decrease the rate of misdiagnosis.

    We report on a 61-year-old woman with a history of right-sided nephrectomy for clear cell renal cell carcinoma (RCC) occurring 21 years ago; she currently presented with a bilateral ovarian tumour. Histologically, the tumour of both ovaries was clear cell carcinoma. Immunohistochemically, the tumour cells were positive for vimentin, RCC marker, epithelial membrane antigen, cytokeratin AE1/3 and CD10. Cytokeratin 7, CA125, HMWCK, estrogen and progesterone receptors were all negative. Based on the morphology and immunophenotype of the tumour, we established a diagnosis of late metastasis of RCC in the ovaries. A postoperative abdominal computed tomography scan, however, revealed a tumour mass solely in the left kidney, which had not been visible in the preoperative ultrasound. The patient underwent nephron-sparing surgery and a biopsy showed the tumour to be clear cell RCC. Metastasis of RCC to the ovaries is rare, and to the best of our knowledge, only 24 cases have been reported to date. However, due to the different treatments and prognosis, the distinction between a primary ovarian tumour and metastasis of RCC is important. PMID:24678363

    We report the first two genetically confirmed cases of primary renal sclerosing epithelioid fibrosarcoma (SEF), occurring in a 17 year-old male and a 61 year-old female. In both cases, the tumors demonstrated the typical epithelioid clear cell morphology associated with extensive hyalinizing fibrosis, raising the differential diagnosis of solitary fibrous tumor, metanephric stromal tumor, and the sclerosing variant of clear cell sarcoma of the kidney. Both neoplasms demonstrated diffuse immunoreactivity for MUC4, a highly specific marker for SEF, and both demonstrated evidence of rearrangement of both the EWSR1 and CREB3L1 genes which have recently shown to be fused in this entity. Both neoplasms presented with metastatic disease. Primary renal SEF represents yet another translocation-associated sarcoma now shown to arise primarily in the kidney. PMID:25353281

    Renal cell carcinoma is the most common malignancy of the kidney in adults. In children, however, it only accounts for an estimated 1.8 to 6.3% of all pediatric malignant renal tumors. Papillary renal cell carcinoma is the second most common type of renal cell carcinoma in children. We present the case of a 12-year-old boy with a 2-month history of abdominal pain, unexplained weight loss, and gross hematuria. Computed tomography revealed a horseshoe kidney and a well-defined mass of 4 cm arising from the lower pole of the right kidney. Microscopically the tumor was composed of papillae covered with cells with abundant eosinophilic cytoplasm and high-grade nuclei with prominent nucleoli. Immunohistochemistry was performed; EMA, Vimentin, and AMACR were strongly positive while CK7, CD10, RCC antigen, TFE3, HMB-45, and WT-1 were negative. Currently, 10 months after the surgical procedure, the patient remains clinically and radiologically disease-free.

    Renal angiomyolipoma is a benign tumor formed by smooth muscle, adipose tissue and blood vessels. It is commonly found incidentally and its clinical manifestations are pain and abdominal mass or spontaneous tumor rupture with retroperitoneal bleeding. The clinical presentation of a hemorrhagic shock secondary to a retroperitoneal hematoma is uncommon. We report a 40 year-old male who presented to the emergency room with lumbar pain and deterioration of hemodynamic parameters. The CT scan showed a left renal injury associated to an expansive retroperitoneal process. The abdominal exploration, vascular control of the renal pedicle and nephrectomy allowed a successful outcome.

    Introduction Metachronous metastatic spread of clinically localized renal cell carcinoma (RCC) affects almost 1/3 of the patients. They occur most frequently in lung, liver, bone and brain. Isolated omental metastasis of RCC has not been reported so far. Case presentation A 62-year-old patient previously diagnosed and treated due to pulmonary sarcoidosis has developed an omental metastatic lesion 13 years after having undergone open extraperitoneal partial nephrectomy for T1 clear-cell RCC. Constitutional symptoms and imaging findings that were attributed to the presence of a sarcomatoid paraneoplastic syndrome triggered by the development this metastatic focus complicated the diagnostic work-up. Biopsy of the [18F]-fluorodeoxyglucose (+) lesions confirmed the diagnosis of metastatic RCC and the patient was managed by the resection of the omental mass via near-total omentectomy followed by targeted therapy with a tyrosine kinase inhibitor. Discussion Late recurrence of RCC has been reported to occur in 10–20% of the patients within 20 years. Therefore lifelong follow up of RCC has been advocated by some authors. Diffuse peritoneal metastases have been reported in certain RCC subtypes with adverse histopathological features. However, isolated omental metastasis without any sign of peritoneal involvement is an extremely rare condition. Conclusion To our knowledge, this is the first reported case of metachronously developed, isolated omental metastasis of an initially T1 clear-cell RCC. Constitutional symptoms, despite a long interval since nephrectomy, should raise the possibility of a paraneoplastic syndrome being associated with metastatic RCC. Morphological and molecular imaging studies together with histopathological documentation will be diagnostic. PMID:26874583

    Renal cell carcinoma comprises about 2% of adult tumors. The overall 10-year survival rate of patients with RCC after nephrectomy is about 18-27%. The incidence of metastasis of initial RCC is about 24-28%, but this rate after nephrectomy is as high as 51%. The most common site of recurrence is the lung, however liver and bone metastases are common. There are many reported cases with late metastasis, however isolated late metastasis in the gastrointestinal tract especially duodenum is very rare. Herein we report our experience with a case of gastrointestinal bleeding secondary to metastatic renal cell carcinoma to duodenum, 16 years after nephrectomy. To the best of our knowledge, about 30 of such cases have been reported in the English literature. Many of the previous cases have been part of disseminated disease and isolated duodenal metastasis is very rare. The longest reported duration between nephrectomy for renal cell carcinoma and duodenal metastasis has been 13 years, thus it seems our case to be also unique because of very late duodenal metastasis.

    Phenazopyridine (Pyridium) is a commonly used urinary tract analgesic. It has been associated with yellow skin discoloration, hemolytic anemia, methemoglobinemia, and acute renal failure, especially in patients with preexisting kidney disease. We report a 17-year-old female with vertically transmitted human immunodeficiency virus (HIV) infection, presenting with acute renal failure and methemoglobinemia following a suicidal attempt with a single 1,200 mg ingestion of Pyridium. She had no prior evidence of HIV nephropathy. The patient had a progressive nonoliguric renal failure on the 3rd day following the ingestion. She was treated with N-acetylcysteine, intravenous carnitine, and alkalinization of the urine. Her kidney biopsy revealed acute tubular necrosis with no glomerular changes. After 7 days of conservative management, she was discharged home with normal kidney function. To our knowledge, this is the second smallest amount of Pyridium overdose resulting in acute renal failure with no previous history of kidney disease.

    We conducted a case-control study of 325 men ages 30-69 who were diagnosed with end-stage renal disease (ESRD) between 1976 and 1984, and resided in four urban areas of Michigan in 1984. Cases were selected from the Michigan Kidney Registry and excluded men with diabetic, congenital, and obstructive nephropathies. Controls were selected by random-digit dialing and were pair-matched to cases for age, race, and area of residence. Telephone interviews were conducted with 69 percent of eligible cases and 79 percent of eligible controls. Risk of ESRD was significantly related to phenacetin or acetaminophen consumption (odds ratio(OR) = 2.66), moonshine consumption (OR = 2.43), a family history of renal disease (OR = 9.30); and regular occupational exposures to solvents (OR = 1.51) or silica (OR = 1.67). Particular occupational exposures with elevated risk were solvents used as cleaning agents and degreasers (OR = 2.50) silica exposure in foundries or brick factories (OR = 1.92), and silica exposure during sandblasting (OR = 3.83). Little or no trend of increased risk with duration of exposure was found for these occupational exposures, with the exception of silica in sandblasting. Limitations of these data include representativeness of cases, possible overreporting by cases, and misclassification of exposures inherent in self-reports.

    Le complicanze vascolari dopo il trapianto renale non sono comuni, e nella maggior parte dei casi si presentano nel periodo post-trapianto precoce. Gli pseudoaneurismi arteriosi coinvolgono l’anastomosi arteriosa del rene trapiantato e nella maggior parte dei casi riconoscono una eziologia micotica. Una donna di 62 anni, che è stata sottoposta otto mesi prima ad un trapianto renale, presentava un vago dolore in fossa iliaca destra. L’ecografia del rene trapiantato dimostrava la presenza di un’area ipoecogena in corrispondenza dell’ilo renale, che all’ecocolordoppler appariva riccamente vascolarizzata. La tomografia computerizzata confermava la diagnosi di pseudo-aneurisma anastomotico di 33 mm di diametro, coinvolgente l’arteria del rene trapiantato. La paziente è stata dunque sottoposta a intervento chirurgico di aneurismectomia, con successivo bypass fra arteria renale del rene trapiantato e arteria iliaca interna. La continuità arteriosa iliaca è stata dunque ristabilita attraverso un by-pass iliaco-esterno-femorale comune in vena safena invertita. L’ecocolordoppler intraoperatorio dimostrava la corretta perfusione del graft renale e la corretta pervietà del by-pass iliacofemorale. Il decorso post-operatorio è stato privo di complicanze significative, eccettuata una linforrea inguinale risolta spontaneamente in 22a giornata post-operatoria. Sei mesi dopo la procedura, la paziente è in ottime condizioni generali, con una funzionalità renale conservata e una corretta pervietà del by-pass iliacofemorale. Lo pseudo-aneurisma dell’arteria renale rappresenta una rara complicanza del trapianto renale. Nella maggior parte dei casi riconosce una eziologia micotica, spesso a causa di contaminazione diretta del graft durante le procedure di prelievo o conservazione dell’organo. Il trattamento è molto complesso, e in molti casi richiede l’espianto del graft. Tuttavia, in alcuni casi selezionati, è possibile eseguire il trattamento dell

    Summary Background Tuberous Sclerosis (TSC) also known as Bourneville disease is a neurocutaneous syndrome having an autosomal dominant inheritance pattern, though the condition has a high rate of spontaneous mutation. It is the second most common neurocutaneous syndrome after neurofibromatosis. This disease demonstrates a widespread potential for hamartomatous growths in multiple organ systems. Case Report We report a case of a 36-year-old female with TSC presenting as massive hematuria with underlying giant bilateral renal angiomyolipomas (AML) with estimated total tumor burden of more than 8 kg which is to the best of our knowledge the highest ever reported. The patient also had lymphangioleiomyomatosis and lesions in the brain, skin, teeth and bones. Conclusions TSC has a wide variety of clinical and radiologic manifestations. It should be suspected when some of the common radiological manifestations are found, including CNS involvement, renal and hepatic AMLs and LAM, even if clinical signs are not obvious. Renal AMLs in setting of TSC may reach giant proportions and may present with massive hematuria. PMID:26491490

    A case of thyroid metastasis of a renal clear cell carcinoma is presented. The fine-needle aspiration cytology pointed out the primary tumor origin. The patient underwent robot-assisted radical nephrectomy and contextual thyroidectomy. During the operative procedure, a neoplastic thrombus extending from the thyroid metastasis and protruding into the internal jugular vein was found. As a result, thrombectomy and ligation of the internal jugular vein were required. In cases of single synchronous thyroid metastases form RCC, radical surgery should be advisable. Robotic approach allows to associate major surgery procedures, as nephrectomy, with radical metastasectomy.

    The aim of the present study was to investigate the treatment options for patients with tuberous sclerosis complex (TSC)-associated renal angiomyolipomas (AMLs). A total of 17 patients who were consecutively diagnosed with TSC-associated renal AMLs at the Department of Urology of Zhongshan Hospital between 1998 and 2012 were included in the study. The patient cohort included 7 males and 10 females with a mean age of 37.6 years (range, 18–62 years). A total of 12 patients were diagnosed with renal AML with TSC during physical examination (PE), while 5 patients were admitted to the Emergency Department of Zhongshan Hospital due to spontaneous rupture of renal AMLs. All renal lesions were examined by ultrasonography and abdominal computed tomography prior to treatment. The primary outcome measure was the kidney reservation rate (patients that had not received nephrectomies) in the rupture group and PE group. Both abdominal ultrasonography and CT revealed AMLs in all patients and the mean tumor size was 10.0±4.0 cm (range, 3.0–17.5 cm). Overall, 9 patients underwent surgery, which included unilateral nephrectomy in 4 patients and unilateral partial nephrectomy/tumor enucleation in 5 patients. The remaining 8 patients received medical treatment. All patients were followed-up for between 10 and 67 months. One patient succumbed as a result of multiple organ failure, which was caused by hypovolemic shock due to the spontaneous rupture of renal AML. The kidney reservation rate during surgery was 87.5% (7/8) in the PE group and 25% (1/4) in the spontaneous rupture group. The management of TSC-associated renal AMLs differs from that of solitary sporadic AMLs. Surgical therapy is recommended following careful risk-benefit analysis. PMID:27446460

    Solitary fibrous tumor (SFT) is a neoplasm of pleura and its occurrence in the retroperitoneal space is rare. We report a case of SFT of the adrenal gland associated with ipsilateral renal cell carcinoma (RCC) and angiomyolipoma (AML). A 48-year-old woman was referred to our hospital for a left renal AML. Computed tomography (CT) in our hospital showed a left adrenal mass (25 x 20 mm). Because the adrenal tumor was nonfunctioning, she was followed at outpatient clinic. Four years later, CT showed an increase in the left adrenal tumor size (42 x 30 mm) and a left RCC. Left adrenectomy and partial nephrectomy for RCC and AML were simultaneously performed. Histological examination revealed adrenal SFT and clear cell carcinoma and AML of the kidney. We present a brief review on histological characteristics of retroperitoneal SFT and its occurrence in the adrenal grand region.

    Angiomyolipoma is a common benign renal tumor. It is typically composed of adipose tissue and hence is easily diagnosed by using imaging methods such as ultrasonography, computed tomography, and magnetic resonance imaging. However, it is difficult to differentiate an atypical angiomyolipoma such as a fat-poor angiomyolipoma from a malignant tumor by using these imaging methods. We report a case of a fat-poor angiomyolipoma with cyst-like changes in a 35-year-old man. The angiomyolipoma was initially suspected to be a cystic renal cell carcinoma according to preoperative imaging studies. A 5-cm cystic tumor with an enhanced septal wall and exophytic formation was present in the middle section of the left kidney. The patient underwent partial nephrectomy. Pathological findings showed necrosis and hematoma in almost the entire lesion, with a small amount of adipose and muscle tissue. Finally, a fat-poor angiomyolipoma was diagnosed.

    Renal vein thrombosis in adults is usually a complication of the nephrotic syndrome. Rarely, it has been reported in nonnephrotic women postpartum. The thrombosis may be a complication of the hypercoagulable state associated with both the nephrotic syndrome and pregnancy. Two postpartum patients with renal vein thrombosis and no prior history of renal disease are reported here. Neither patient had heavy proteinuria. In both cases, pyelonephritis was suspected clinically and the diagnosis of renal vein thrombosis was first suggested and confirmed by radiologic examination. Renal vein thrombosis should be considered in women presenting postpartum with flank pain.

    A 57-year-old woman was admitted to National Defense Medical College hospital for treatment of gastric cancer with pyloric stenosis. She had been diagnosed with chronic kidney disease (CKD) 10 years prior, but received no hemodialysis. Because of peritoneal dissemination, a palliative distal gastrectomy was performed. In consideration of renal dysfunction, we decided for chemotherapy with paclitaxel, but not S-1 plus cisplatin regimen which is renal toxic agents. On the 29th postoperative day, chemotherapy using paclitaxel was initiated at a dose of 80 mg/m(2). Paclitaxel was administered weekly on days 1, 8, and 15 on a 28-day cycle. The patient tolerated 13 courses of this treatment without any severe adverse effect, such as exacerbation of renal function. Despite the gradual increase in the level of tumor markers, metastases were not detected via radiography during the clinical course. Moreover, renal function was maintained for the duration of the clinical course. To date, standard chemotherapeutic treatment for patients with CKD has not been established. We conclude that weekly paclitaxel is a suitable treatment regimen for patients with renal failure requiring chemotherapy for advanced gastric cancer. PMID:27656282

    The finding on imaging (computed tomography scan or magnetic resonance imaging) of synchronous malignant renal mass in patient with an active nonrenal malignancy without renal specific symptoms is not frequent and diagnostic evaluation can be challenging. We describe a 54-year-old Moroccan male former chronic smoker who presented to our hospital with dry cough and impairment of the performance status. The imaging found a tumor mass in the left upper lobe of the lung associated to mediastinal lymph node and a scanno-guided biopsy of this tumor showed a non small cell lung cancer. The radiological staging revealed a solitary renal mass in the right kidney. The patient received firstly two cycles of a lung cancer chemotherapy with a partial response in the lung and a stability of the renal mass. Consequently, he underwent a scanno-guided biopsy of this mass which confirmed a synchronous clear cell renal carcinoma. The patient got chemo radiotherapy for the lung cancer and then after that he got a partial nephrectomy. He is still under a good control with more than 2 years after the initial diagnosis.

    Spontaneous renal vein thrombosis (RVT) is very rare in the absence of nephrotic syndrome. It is more common in newborns and infants. RVT should always be included in the differential diagnosis of flank pain and hematuria, and because RVT can induce acute renal injury. A 19-year-old man was admitted to our hospital because he complained of right flank pain and oliguria for 3 days. Another patient, a 24-year-old man, complained of a severe and sudden onset of bilateral flank pain and anuria for a day. They were both healthy before they developed the described symptoms and had different levels of decrease in renal function when they visited the hospital. Color Doppler ultrasonography revealed RVT in both the patients. The patients received therapy, including anticoagulation and thrombolysis, following their diagnoses, and they recovered in a few days.

    Focal segmental glomerulosclerosis (FSGS) causes glomerular lesions that can progress to end-stage renal disease. It is suspected to be caused by a circulating factor that is amenable to plasmapheresis removal and exhibits a risk for recurrence in the renal allograft. We present two patients with FSGS recurrence in their allograft kidneys diagnosed by biopsy after significant proteinuria developed in the posttransplant setting. Treatment with therapeutic plasma exchange induced long-term remission in both patients. Spot urine protein:creatinine ratios were monitored and treatment was continued until a target of <0.5 was achieved. In patient number two, a second peak in proteinuria and azotemia was ultimately attributable to ureteral stenosis and these values normalized following repair. In conclusion, therapeutic plasma exchange is an effective treatment for FSGS recurring following renal transplant.

    Transmural or endovascular invasion of regional veins is often a characteristic of malignant renal neoplasms. Tumor thrombus that ascends in the inferior vena cava and sometimes invades the heart seldom adheres to intima. Radical surgical management of malignant renal neoplasms necessitates concomitant extraction of tumor thrombus. This may be achieved by cavotomy alone, but often resection of portions of the suprarenal inferior vena cava (either partial mural cavectomy, or circumferential cavectomy) is also required. Atriotomy is mandatory whenever intracardiac tumor thrombus exists. Most of the 187 reported operations for venous extension related to malignant renal neoplasms were done in the past decade. Technical problems have included embolism, hemorrhage, and incomplete removal. Because the left kidney is endowed with vast collateral venous channels, right nephrectomy and suprarenal caval interruption are usually well tolerated. Conversely, since the right kidney lacks venous collaterals, survival after left nephrectomy and suprarenal cavectomy hinges on creation of a shunt to divert venous outflow from the remaining kidney.

    Lymphocele after renal transplantation is a complication that often requires surgical treatment. We performed laparoscopic drainage for the postoperative lymphocele in two renal transplantation patients. The patients were suffering from perineal discomfort and urinary frequency due to the lymphocele after the renal transplantation. Percutaneous catheter drainages and injections of tissue sclerosing agents such as povidone-iodine solution and tetracycline were not effective. Then fenestration of the lymphocele by laparoscopic technique was done. This procedure made the lymphatic fluid free from the lymphocele in the retroperitoneal space to the peritoneal cavity following creation of a peritoneal window. There were no apparent complications. The patients were free from symptoms and had no relapse 10 months after the operation. We report the procedure and the results of the laparoscopic fenestration.

    Left venous renal entrapment syndrome was observed during multidetector 64-row computer tomography and color Doppler ultrasonography in a 58-year-old Caucasian female hospitalized due to choledocholithiasis. The patient demonstrated no typical symptoms of nutcracker syndrome. The left renal vein (LRV) was compressed as it passed between the superior mesenteric artery and the right renal artery. The LRV lumen measured 1.7 × 7.8 mm (width × height) at the point of narrowing and 7.5 × 17 mm before this. Secondary to the nutcracker phenomenon, the course of left ovarian vein was winding and was significantly wider than the contralateral vessel.

We herein present the first Turkish patient with HDR syndrome, who has a p.R367X mutation. This report indicates that p.R367X is not a mutation specific for the Far Eastern populations and also that urological findings in infants with hypoparathyroidism should be carefully examined because clinical findings relating to the p.R367X mutation may show a variable age of onset.

    The left renal vein (LRV) has many developmental variations; the two most common are the circumaortic and the retrocaval. Anterior nutcracker syndrome is the compression of the LRV between the aorta and superior mesenteric artery, whereas posterior nutcracker syndrome occurs between the vertebral column and the aorta. An adolescent male (aged 16 years) was referred to the emergency department for flank pain. CT findings showed the combination of anterior and posterior nutcracker syndrome in the left circumaortic renal vein, which has not previously been described in an adolescent.

    Xp11.2 translocation renal cell carcinoma (Xp11.2 RCC) with PSF-TFE3 gene fusion is a rare neoplasm. Only 22 cases of Xp11.2 RCCs with PSF-TFE3 have been reported to date. We describe an additional case of Xp11.2 RCC with PSF-TFE3 showing melanotic features. Microscopically, the histologic features mimic clear cell renal cell carcinoma. However, the dark-brown pigments were identified and could be demonstrated as melanins. Immunohistochemically, the tumor cells were widely positive for CD10, human melanoma black 45, and TFE3 but negative for cytokeratins, vimentin, Melan-A, microphthalmia-associated transcription factor, smooth muscle actin, and S-100 protein. Genetically, we demonstrated PSF-TFE3 fusion between exon 9 of PSF and exon 5 of TFE3. The patient was free of disease with 50 months of follow-up. The prognosis of this type of tumor requires more cases because of limited number of cases and follow-up period. Xp11.2 RCC with PSF-TFE3 inevitably requires differentiation from other kidney neoplasms. Immunohistochemical and molecular genetic analyses are essential for accurate diagnosis. PMID:25582502

    Granulomatous interstitial nephritis (GIN) is a rare manifestation of renal tuberculosis (TB). We report a case of rapidly progressive renal failure (RPRF), granulomatous inflammation of cervical lymph node and GIN as presenting manifestations of TB. Aspiration cytology of cervical lymph node showed granulomatous necrotizing inflammation with acid-fast bacilli (AFB). The renal biopsy and urine specimen did not show AFB. Urine polymerase chain reaction (PCR) for Mycobacterium tuberculosis was positive. We observe that GIN due to TB can present as RPRF and emphasize the value of PCR-based techniques in making a correct diagnosis. PMID:25984199

    Renal failure (RF) reversal in multiple myeloma (MM) is associated with an improved prognosis. Light chain myeloma, serum creatinine (SCr) > 4 mg/dL, extensive proteinuria, early infections, and certain renal biopsy findings are associated with lower rates of RF reversal. Our patient is a 67-year-old female with multiple poor prognostic factors for RF reversal who demonstrated a rapid renal response with bortezomib and dexamethasone (BD) regimen. She presented initially with altered mental status. On exam, she appeared lethargic and dehydrated and had generalized tenderness. She had been taking ibuprofen as needed for pain for a few weeks. Labs showed a white cell count—18,900/μL with no bandemia, hemoglobin 10.8 gm/dL, potassium—6.7 mEq/L, bicarbonate—15 mEq/L, blood urea nitrogen—62 mg/dL, SCr—5.6 mg/dL (baseline: 1.10), and corrected calcium—11.8 mg/dL. A rapid flu test was positive. Imaging studies were unremarkable. Her EKG showed sinus tachycardia and her urinalysis was unremarkable. The unexplained RF in an elderly individual in conjunction with hypercalcemia and anemia prompted a MM work-up; eventually, lambda variant MM was diagnosed. An immediate (4 days) renal response defined as 50% reduction in SCr was noticed after initiation of the BD regimen. PMID:25045553

    The efficacy and safety of biologic treatments have been established in patients with moderate to severe psoriasis, but there are few reports on biologic therapy for patients with psoriasis complicated by end-stage renal failure on hemodialysis (HD). In this report, we demonstrated the efficacy and safety of adalimumab for patients with severe psoriasis on HD. A 46-year-old Japanese man with a 14-year history of psoriasis was referred to our clinic in September 2009. He had developed hypertension and renal failure during a 7-year history of cyclosporin treatment. With the infliximab treatment, he achieved 75% improvement of the Psoriasis Area and Severity Index (PASI) score within 3 months from the PASI of 42.3 before the treatment. However, his renal failure gradually deteriorated, and HD was initiated at 1 year after the introduction of infliximab. Because of hydration during the i.v. injection of infliximab, he developed pulmonary edema with every infliximab treatment after starting HD. We switched to ustekinumab treatment, but his psoriasis was not improved. Then, we switched to adalimumab and achieved a PASI-100 response within 2 months. The patient received adalimumab treatment for more than a year without any adverse effects. In addition to our case, five articles reported cases of psoriasis patients with renal failure on HD who were treated with biologics. The psoriatic lesions were improved by biologics in these cases, and no severe adverse effects on the renal function were reported. Thus, biologics are a reasonable treatment option for patients with severe psoriasis with renal failure on HD.

Her renal pathology consisted of widespread κ light chain protein deposition associated with the formation of large quantities of rod-like crystals in podocytes. This phenomenon is very rare. We explored the significance of this crystal formation via a detailed and descriptive analysis and also performed a literature review, thus providing data to increase the available information about this type of disease.

    Retroperitoneal haemorrhage (or retroperitoneal haematoma) refers to an accumulation of blood found in the retroperitoneal space. It is a rare clinical entity with variable aetiology including anticoagulation, ruptured aortic aneurysm, acute pancreatitis, malignancy, and bleeding from renal aneurysm. Diagnosis of retroperitoneal bleed is sometimes missed or delayed as presentation is often nonspecific. Multislice CT and arteriography are important for diagnosis. There is no consensus about the best management plan for patients with retroperitoneal haematoma. Stable patients can be managed with fluid resuscitation, correction of coagulopathy if any, and blood transfusion. Endovascular options involving selective intra-arterial embolisation or stent-grafts are clearly getting more and more popularity. Open repair is usually reserved for cases when there is failure of conservative or endovascular measures to control the bleeding or expertise is unavailable and in cases where the patient is unstable. Mortality of patients with retroperitoneal haematoma remains high if appropriate and timely measures are not taken. Haemorrhage from a benign renal tumour is a rarer entity which is described in this case report which emphasizes that physicians should have a wide index of suspicion when dealing with patients presenting with significant groin, flank, abdominal, or back pain, or haemodynamic instability of unclear cause. Our patient presented with features of acute abdomen and, being pregnant, was thought of having a ruptured ectopic pregnancy. PMID:27429809

    Anophthalmos with limb anomalies (Waardenburg Opththalmo-Acromelic Syndrome) is a very rare autosomal recessive multiple congenital anomaly syndrome, first described by Waardenburg et al. in 1961 (MIM 206920). It is characterized by mono or more often bilateral anophthalmia/microphthalmia and foot malformations, which can be observed in 91% of the patients. The most common anomaly of the feet is the presence of four toes. The hands are affected bilaterally in 77% of the cases. The most characteristic anomaly is the synostosis of the fourth and fifth metacarpals. To date, 33 cases from 19 families have been reported. We present an Italian case of anophthalmia with limb anomalies and a renal malformation, which has never been described in the literature.

    We report a 50-year-old male patient with diabetes mellitus and hypertension who presented with low-grade fever, anuria and renal failure. He had no prior history of nephropathy and retinopathy. Since anuria persisted, a renal biopsy was performed using automated gun, under ultrasound guidance. Two hours after the renal biopsy was performed, the patient developed severe left loin pain that required analgesics and sedatives. Ultrasound of the abdomen performed immediately, two hours and four hours after the biopsy, did not reveal any hematoma. The hemoglobin was stable when the patient developed loin pain, but after eight hours decreased to 9.1 g/dL, and computed tomography scan of the abdomen revealed a big peri-nephric hematoma around the left kidney. He was managed with blood transfusions and a selective angiogram was done. It revealed a pseudoaneurysm and arterio-venous fistula from the segmental artery of lower pole of the left kidney; both were closed by using microcoils and liquid embolic agent N-butyl-cyanoacrylate (NBCA). The only risk factor the patient had at the time of renal biopsy was severe renal failure. Our case suggests that severe loin pain immediately after renal biopsy in a patient with renal failure warrants careful follow-up of hemoglobin and imaging, even if initial imaging is normal. Further fall of hemoglobin necessitates early evaluation with angiogram, which helps in diagnosing the treatable, although rare, complications like pseudoaneurysm and arterio-venous fistula.

    Crossed renal ectopia is a rare urinary system anomaly which mostly is asymptomatic and is diagnosed incidentally. Urinary obstruction, infection, and neoplasia of the urinary system and nephrolithiasis are main complications of this anomaly. A 6-year-old boy admitted to the hospital with colicky abdominal pain and nausea. Abdominal examination revealed tenderness in right lower quadrant. Urine analysis and culture were normal. Kidney ultrasonography showed right kidney in pelvis cavity with no kidney tissue in left side. TC 99-DMSA scan demonstrated no radiotracer accumulation in the normal renal area. Radiotracer accumulation was seen in the pelvis area with a deviation to the left. Voiding cystoureterogram revealed right sided grade II vesicoureteral reflux. Severe urological anomalies in children may be asymptomatic or have nonspecific symptoms such as abdominal pain. PMID:27689123

    Little information is available regarding the correlation between Prader-Willi syndrome and urolithiasis. We report a patient with Prader-Willi syndrome with a renal uric acid (UA) stone. A 23-year-old male patient was admitted to our department with gross hematuria and left flank pain. The blood and urine examination demonstrated hyperuricemia with the presence of UA crystals in the urine. Excretory urography revealed a radiolucent stone (17 x 27 mm) in the left renal pelvis suggesting a UA stone. The stone was removed successfully using extracorporeal shockwave lithotripsy (ESWL) combined with medication for UA metabolism. The stone was thought to have formed as a result of overeating associated with Prader-Willi syndrome, and accompanying overproduction of purine.

    Arthrogryposis-renal dysfunction-cholestasis syndrome is a rare lethal disorder that involves multipl organ system. It is inherited autosomal recessive and caused by defects in the VPS33B and VIPAR genes. Three cardinal findings of this syndrome are arthrogryposis, renal tubular dysfunction and cholestasis.The other organ involvements including ichthyosis, central nervous system malformation, platelet anomalies, congenital heart defects and severe failure to thrive are sometimes associated with this syndrome. Clinical findings, organ biopsy and mutational analysis can help for diagnosing but there is no curative treatment except supportive care. Several symptoms of this condition are already usually present in the neonatal period: arthrogryposis, neonatal cholestasis, skin lesions, among others. Usually survival is until the first year of life. We present a newborn whose evolution was rapidly fatal.

    Renal transplant recipients who have sickle cell disease are at risk of infection, recurrent graft disease, and sickling crisis that affects the long-term outcome. We report a patient of sickle cell trait who developed patchy cortical necrosis in the perioperative period but had a good long-term outcome. The renal cortical necrosis was presumed to be secondary to cyclosporine-basiliximab interaction in the backdrop of sickling trait. The patient additionally had spontaneous closure of vascular access and severe hypertension immediately following transplantation suggestive of vaso-occlusive crisis. Cyclosporine and basiliximab drug interaction needs to be recognized and steps need to be taken in patients to avoid perioperative graft dysfunction. PMID:22022093

    We present a patient who had ingested sodium bicarbonate for treatment of alcoholic dyspepsia during forty years at increasing doses. During the last year he had used more than 50 grams daily. He presented with metabolic alkalosis, epileptic convulsions, subdural hematoma, hypertension and rhabdomyolysis with end stage renal failure, for which he had to be given regular intermittent hemodialysis treatment. Untreated hypertension and glomerulonephritis was probably present prior to all these acute incidents. Examination of the kidney biopsy revealed mesangial proliferative glomerulonephritis and arterial wall thickening causing nephrosclerosis together with interstitial calcinosis. The combination of all these pathologic changes might be responsible for the development of progressive chronic renal failure ending up with the need for continuous intermittent hemodialysis treatment.

    Patients with ureteropelvic junction (UPJ) obstruction can present with flank pain or hematuria. We present 20-year-old male presenting with acute pain in lumbar and right fossa with tenderness and guarding, this case was clinically mimicking general surgical emergency. On computed tomography with urography and angiography, there was 15 cm × 11 cm × 10 cm size non-enhancing hyperdense lesion (average Hounsfield units - +64) in right renal pelvis suggestive of hematoma. Patient's diethylenetriaminepentaacetic acid diuretic renography was suggestive of right kidney glomerular function rate of 48.4 ml/min with the relative function of 43%, Peak to half peak was not achieved. The patient was managed by retrograde ureteropyelography and double J stenting. After 1 month, clot size decreased to 4 cm × 3 cm × 2 cm. The patient had undergone open reduction Anderson hynes dismembered pyeloplasty with the removal of pelvis clot after 6 weeks. We report the first case of UPJ obstruction presenting as an acute abdomen and spontaneous hematuria with large pelvis clot without rupture of the renal pelvis. PMID:27141202

    Multiple myeloma (MM) is a rare hematological malignancy, characterized by uncontrolled proliferation of plasma cells in the bone marrow. MM is usually confined to the bone marrow, however, it may occasionally infiltrate other tissues, which is known as extramedullary plasmacytoma (EMP). The majority of EMPs involve the head and neck region, although different anatomical sites, including the gastrointestinal tract, central nervous system, thyroid gland and breast may also be affected. The simultaneous presentation of EMP in the kidney and head is rare, presenting diagnostic challenges due to its unusual location and non-specific or absent symptoms. To the best of our knowledge, no case of extramedullary plasmacytoma presenting with simultaneous renal and intracranial infiltration has been reported in the literature thus far. However, the present study reports a case of primary renal and intracranial extramedullary plasmacytoma in a 76-year-old male patient. The patient presented with a swelling over the right side of the forehead, which had slowly increased in size prior to hospital admission. The swelling was associated with dizziness and weakness, without bone pain. Contrast magnetic resonance imaging suggested an osteolytic skull lesion with intracranial extension. Abdominal enhanced computed tomography scanning revealed a large tumor mass extending around and into the kidneys. Immunohistochemical examination of the renal tumor biopsy, and blood and serum samples, as well as immunoelectrophoresis of serum proteins, resulted in a diagnosis of EMP being proposed. Therefore, the patient was administered with two cycles of cyclophosphamide and thalidomide in combination with dexamethasone. Follow-up imaging performed 4 months later revealed almost complete disappearance of the intracranial tumor mass and renal infiltration. The current study also presented a review of the literature. This study revealed that EMPs may co-exist with MM or present as the main symptom

While coagulase-negative staphylococci, S.aureus, and Escherichia coli are the most common causes of catheter-related infections in haemodialysis patients, such infections caused by Pseudomonas aeruginosa are relatively rare. Here, we present an unusual case of 36-year-old male patient with chronic renal failure, who developed endocarditis and sepsis from Pseudomonas aeruginosa infection of the left hand arteriovenous fistula. The bacteraemia in the present case caused multiple complications including dry gangrene of bilateral lower limbs, stroke, endophthalmitis, left brachial artery thrombosis and vegetations on the interventricular septum and aortic wall. Despite antibiotic treatment, the patient suffered a cardiac arrest and could not be revived. PMID:27630891

    The aim of the present study was to assess the morbidity of ampullary renal pelvis (ARP) and document its natural history in post-natal life. A total of 1,167 newborn infants with prenatally suspected hydronephrosis were retrospectively analyzed. Of these, 65 patients were diagnosed with ARP by computed tomography urography (CTU) and/or magnetic resonance urography (MRU). All cases were followed up with ultrasonogrophy at 1, 3, 6 and 12 months after birth, and one case was followed up for 5 years. Changes in the separation of the renal pelvis collection system were recorded. Children with ARP accounted for 5.57% of the total cases (65/1,167) followed-up. No lack of connection between the renal calyces and the renal pelvis was detected. The long-term follow-up revealed that the separation of the renal pelvis collection system did not tend to increase over time. In addition to imaging examinations, long-term follow-up observation is recommended for the accurate diagnosis of pediatric ARP, particularly for differentiation from hydronephrosis. PMID:25452792

Both patients had complete duplex and were investigated by ultrasound, micturating cystourethrogram, magnetic resonance urography, and radioisotope scan. One patient had high-grade vesicoureteral reflux to lower moiety complicated with recurrent urinary tract infections, while the other had obstruction to upper moiety due to ectopic ureter. The pathological moieties of both patients were functional. Both patients underwent laparoscopic ipsilateral ureteroureterostomy uneventfully without any intraoperative complications. Postoperative imagings confirmed successful outcomes after surgery. PMID:27014651

Ultrasound, transurethral resection of the bladder mass with subsequent histological analysis, thoracic and abdominal computed tomography-scan and brain magnetic resonance imaging were performed. He was diagnosed with a bladder metastasis of clear cell renal cell carcinoma (RCC) with concomitant bone, pulmonary, and cerebral metastatic disease of a primary RCC of the right kidney. Management: Transurethral resection of the bladder mass, cerebral and bone radiotherapy, removal of the primary tumor, targeted systemic therapy with mTOR followed by tyrosine kinase inhibition.

    The contribution of renal needle biopsy (RNB) to make a diagnosis, a treatment selection and a prognostic evaluation of nephropathies is significant. No Moroccan study has evaluated the practice and the contribution of RNB. Our aim was to study RNB indications, to determine the frequency of kidney diseases identified by RNB in our region and make a comparison between clinical and biological data and histological diagnosis. This is a retrospective study conducted between January 2009 and December 2012. We included all patients in the Department of Nephrology, CHU Hassan II, Fez, who underwent biopsy of native kidneys. 522 RNB were performed. We excluded 8 biopsies due to lack of informations and 514 were retained. The average age of the patients at the time of RNB was 39±17 years (3-82 years). Sex ratio was 0.9. Nephrotic syndrome was the most common clinical diagnosis to all ages (58.2%). Glomerular nephropathies represent 94,2% of diagnosed renal diseases, their distribution varies according to patients' age. RNB confirmed the first clinically suspected diagnosis in 40.65% of cases, whereas it revealed an unexpected diagnosis in 22.5% of them. Syndromic diagnosis can orient the clinician toward the most probable kidney disease and guide any emergency treatment while awaiting RNB results. But it can never replace RNB which remains the gold standard. PMID:27583085

    In rare instances, recipients of organ transplants from human T-lymphotropic virus type I- (HTLV-I-) positive donors reportedly developed neurologic symptoms due to HTLV-I-associated myelopathy (HAM). We present herein two cases of HAM associated with renal transplantation from HTLV-I seropositive living-donors. The first patient was a 42-year-old woman with chronic renal failure for twelve years and seronegative for HTLV-I. She underwent renal transplantation with her HTLV-I seropositive mother as the donor, and she developed HAM three years after the transplantation. The second patient was a 65-year-old man who had been suffering from diabetic nephropathy. He was seronegative for HTLV-I and underwent renal transplantation one year previously, with his HTLV-I seropositive wife as the donor. He developed HAM eight months after renal transplantation. Both cases showed neurological improvements after the immunomodulating therapies. We tried to shed some light on the understanding of immunological mechanisms of transplantation-associated HAM, focusing on therapeutic strategies based on the immunopathogenesis of the condition.

    Abstract Premature ventricular complexes are very common, appearing most frequently in patients with hypertension, obesity, sleep apnea, and structural heart disease. Sympathetic hyperactivity plays a critical role in the development, maintenance, and aggravation of ventricular arrhythmias. Recently, Armaganijan et al reported the relevance of sympathetic activation in patients with ventricular arrhythmias and suggested a potential role for catheter-based renal sympathetic denervation in reducing the arrhythmic burden. In this report, we describe a 32-year-old hypertensive male patient presenting with a high incidence of polymorphic premature ventricular complexes on a 24 hour Holter monitor. Beginning 1 year prior, the patient experienced episodes of presyncope, syncope, and tachycardia palpitations. The patient was taking losartan 100 mg/day, which kept his blood pressure (BP) under control, and sotalol 160 mg twice daily. Bisoprolol 10 mg/day was used previously but was not successful for controlling the episodes. The 24 hour Holter performed after the onset of sotalol 160 mg twice daily showed a heart rate ranging between 48 (minimum)–78 (average)–119 (maximum) bpm; 14,286 polymorphic premature ventricular complexes; 3 episodes of nonsustained ventricular tachycardia, the largest composed of 4 beats at a rate of 197 bpm; and 14 isolated atrial ectopic beats. Cardiac magnetic resonance imaging with gadolinium perfusion performed at rest and under pharmacological stress with dipyridamole showed increased left atrial internal volume, preserved systolic global biventricular function, and an absence of infarcted or ischemic areas. The patient underwent bilateral renal sympathetic denervation. The only drug used postprocedure was losartan 25 mg/day. Three months after the patient underwent renal sympathetic denervation, the mean BP value dropped to 132/86 mmHg, the mean systolic/diastolic 24 hour ambulatory BP measurement was reduced to 128/83

    We describe the rare case of a 68-year-old gentleman with the history of a hand-assisted laparoscopic left radical nephrectomy for a T2bN0M1 clear cell renal cell carcinoma (RCC). Seven years after surgery and with clean surveillance imaging for metastasis/recurrence the patient presented with three separate tumors suspicious for malignancy. A bladder lesion was found during workup for hematuria, a stomach lesion during diagnostic endoscopy, and a testicular lesion during self-exam. He underwent transurethral resection of bladder tumor, left inguinal orchiectomy, and upper endoscopic ensnarement. All specimens surprisingly showed RCC by histology and immunostaining. These three sites are rare for RCC metastasis and simultaneous presentation is even rarer, further emphasizing the importance of continuous and careful follow-up in this patient population, despite what could appear as complete remission.

    We report on two additional cases of metformin-associated encephalopathy in patients with end-stage renal disease (ESRD) undergoing hemodialysis. Two patients were seen at our hospital with abnormal neurological signs and symptoms. Magnetic resonance imaging (MRI) revealed the same pattern of high signal intensity in both basal ganglia in T2-weighted images in the two patients. The two patients had started taking metformin 5 and 6 weeks earlier at the same dose of 1000 mg per day. Metformin was immediately stopped, and regular hemodialysis was conducted. Their signs and symptoms resolved completely after these measures. The high signal intensity in both ganglia in T2-weighted MRI also disappeared. We should suspect metformin-induced encephalopathy and withdraw the drug when presented with diabetic patients with chronic kidney disease and neurological signs and symptoms of unknown cause.

    Iliac vein-ureteral fistula is a rare cause of hematuria. The diagnosis of an iliac vein-ureteral fistula can be elusive even with the use of multiple methods. With regards to the treatment, there appears to be a shift in management from primarily open surgical to primarily angiographic management. We present a unique case of an external iliac vein – transplant ureteral fistula. A 48 year-old female complained of recurrent gross hematuria. She underwent transplant nephrectomy and radical left nephrectomy because of rejection of transplanted kidney and cystic renal cell carcinoma when the hematuria arose for the first time. Ten months later, the hematuria recurred again, and cystoscopy showed bleeding from the right transplant ureteral orifice. Open exploration confirmed the diagnosis of external iliac vein – transplant ureteral fistula. Diagnostic difficulties and treatment dilemma of such a rare cause of hematuria are also discussed.

In the initial evaluation he appeared acutely ill and had resting dyspnea, edema and jaundice. His initial laboratory assessment disclosed azotemia, elevated lactate dehydrogenase levels, a low hemoglobin concentration (4.9 /dL) and a high corrected reticulocyte count (4,7%) with negative direct and indirect Coombs' test. The patient was transferred to the ICU, where he received support therapy with hemodialysis, mechanical ventilation, vasoactive drugs and transfusions of packed red cells. The evolution after 1 month was favorable and he was discharged without anemia and with normal renal function. Three months after discharge, the glucose-6-phosphate-dehydrogenase screening study did not demonstrate detectable enzymatic activity. PMID:23282778

    A case-control study involving 406 incident cases and 2,434 controls was conducted in Iowa to examine the association between occupational exposures and renal cell carcinoma risk. After adjusting for major confounders, an increased risk was observed for men among mechanics and repairers (odds ratio [OR] 1.9, 95% confidence interval [CI] = 1.2-2.9); assemblers (OR 2.5, 95% CI = 0.8-7.6); automotive dealership and service station employees (OR 1.9, 95% CI = 0.9-3.9); wholesale traders of durable goods (OR 1.5, 95% CI = 0.7-3.2); farm product vendors (OR 4.4, 95% CI = 1.3-15.5); service organization managers (OR 2.2, 95% CI = 1.0-5.1); financial specialists (OR 2.7, 95% CI = 1.0-7.6); sales occupation supervisors (OR 1.8, 95% CI = 1.0-3.3); guards (OR 5.4, 95% CI = 1.4-20.7); and general farm workers (OR 1.9, 95% CI = 1.0-3.7). Among women, an increased risk was found for employees in depository institutions (OR 3.6, 95% CI = 1.1-11.3); colleges and universities (OR 7.6-95% CI = 2.3-25.6); and retail, including those in grocery stores (OR 2.2, 95% CI = 1.0-4.7). Our results indicate that occupational exposures may increase the risk of renal cell carcinoma. PMID:15091286

    Mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome is a progressive syndrome with variable involvement of multiple-organ systems. These patients require special consideration for preoperative optimization, intraoperative management, and postoperative care. The medical literature regarding perioperative management of these patients relies heavily on case reports. Here we present a novel experience providing care for a patient with mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes syndrome who underwent renal transplantation for focal segmental glomerulosclerosis and end-stage renal disease.

    Renal cell carcinoma is reported to have potent angiogenic activity with a high microvascular density in both primary and metastatic sites compared with other adenocarcinomas. Angiogenesis can lead to the formation of abnormal arteriovenous shunts that can, in patients with peripheral vascular disease, result in worsening of the degree of ischaemia by producing a vascular steal-like phenomena. Nevertheless, steal phenomena secondary to malignancies are extremely rare. We report a case of distal critical limb ischaemia in a patient with peripheral vascular disease exacerbated by massive arteriovenous shunting due to tibial metastases from renal cell carcinoma.

    Introduction Renal lymphangiomatosis is a rare congenital benign disease of renal lymphatic system, here we are presenting a very rare form of disease which is bilateral form. Presentation of the case A young adult presented to our clinic after being referred from primary care clinic with intermittent bilateral flank pain and no other symptoms after extensive radiological investigations diagnosis has been made and confirmed by radiological finding of disease. Active treatment usually preserved for complex cases and for the complications of the disease but in our patient as needed analgesia worked well in controlling his intermittent pain and his wish not to pursue any intervention. The vague presentation with initial imaging rising suspicion of renal tumor or complex renal cyst might cause psychological street on the patient, which our patient had, but reassurance after extensive radiological work up relive that's stress. Discussion Although it is very rare disease to be bilateral but wide variety of other differential diagnoses make importance of disease recognition and accurate diagnosis is the key. Conclusion Renal lymphangiomatosis is a rare benign disease of renal lymphatic, which usually affect one side, but bilateral form is very rare form, which may raise the suspicions of genetic form of renal malignancy. Accurate diagnosis requires work up to role out malignant and other renal tumor, which require active surgical management. PMID:26719997

    A five years old boy was bitten by a Merrem's hump-nosed viper (Hypnale hypnale) in Central Province, Sri Lanka. He developed local swelling, incoagulable blood, thrombocytopenia, bleeding into the gastrointestinal tract, and acute renal failure. Treatment with Serum Institute of Indian polyspecific antivenom (specific for venoms of cobra, common krait, Russell's viper and saw-scaled viper) had no effect on the coagulopathy, which persisted for more than a week. The boy recovered after 27 d in hospital, during which he was treated with peritoneal dialysis for renal failure. Laboratory studies demonstrated that the venom of H. hypnale was procoagulant, fibrinolytic and aggregated platelets. This first authenticated case of life-threatening acute renal failure and haemostatic disturbances caused by H. hypnale, a species responsible for 27% of snake bites in Sri Lanka, demonstrates the need for a new antivenom with specific activity against the venom of this species.

    Although the second peak of the age distribution of rhabdomyosarcoma (RMS) is at adolescence, renal RMS is extremely rare at this age group. This tumor is indistinguishable from other renal tumors based on clinical and imaging findings, and the diagnosis relies on histology and immunohistochemical staining. We report a unique case of adolescent renal RMS associated with tumor thrombus extending into the inferior vena cava (IVC) and right atrium.An 18-year-old female adolescent presented with shortness of breath and palpitations, associated with right flank discomfort, and hematuria. A pleomorphic-type renal RMS with Budd-Chiari syndrome and arrhythmia induced by IVC and RA thrombosis was diagnosed. Despite complete tumor resection, the patient developed multiple lung metastases a month after surgery. Chemotherapy was recommended, but the patient declined. She died within a year of the initial operation.Adolescent renal RMS is rare and associated with poor outcome. Early aggressive multimodal therapy seems to be appropriate, in particular, in the presence of tumor thrombosis. PMID:27227946

    Clear cell papillary renal cell carcinoma (CCPRCC) is a renal neoplasm that has recently received widespread recognition in the literature. There have been several reports of this tumor arising in a sporadic setting and in patients with end-stage renal disease; however, there is limited information available about the clinical, pathologic, and genetic characteristics of this tumor in the setting of von Hippel-Lindau (VHL) disease. We herein report a series of 3 patients who developed CCPRCC in this unique clinical setting. The histology and immunohistochemical profile for all 3 cases was similar to that which has been previously reported for CCPRCC. All tumors were diffusely and strongly positive for cytokeratin 7, negative for α-methyl-CoA-racemase, and showed at least focal staining for CD10. Comparative genomic analysis was performed on tumors from all 3 patients. One tumor demonstrated monosomy 3, and the other 2 tumors showed normal chromosomal content. All 3 patients were alive without evidence of disease progression 5, 3, and 3 years after surgery. CCPRCC represents a distinct tumor type that may occur in the setting of VHL disease and should be considered in the differential diagnosis of extensively cystic renal tumors arising in this clinical setting. Molecular analysis in our series of cases suggests that CCPRCC does indeed represent a unique histologic subtype and must be distinguished from clear cell renal cell carcinoma due to different biological potentials. Ancillary studies for accurate classification are recommended due to significant morphologic overlap with clear cell renal cell carcinoma. PMID:25081542

    Hyponatremia is one of the electrolyte abnormalities frequently encountered in cancer therapy. Cisplatin is a well-known drug which can raise various adverse events, including hyponatremia. A male with advanced oropharyngeal cancer is presented in the present report, who was treated with radiotherapy with concurrent administration of cisplatin and who underwent a total of three episodes of severe hyponatremia in the course of therapy. The first two attacks of hyponatremia following cisplatin administration were accompanied by dehydration and excessive urination, and the patient recovered in one week with rehydration and salt supplementation. Excessive loss of salt in urine confirmed that these events were caused by renal salt wasting syndrome after cisplatin administration. On the other hand, the third attack was due to the syndrome of inappropriate antidiuretic hormone secretion after surgery for a bone fracture. Estimation of the extracellular fluid volume and salt intake/output balance is always believed to be necessary for the diagnosis and proper management of severe hyponatremia after chemotherapy-based treatment with cisplatin.

    A 69-year-old man had undergone left ureteronephrectomy because of a left renal pelvic tumor, however the pathological diagnosis was inflammatory pseudotumor. About 1 year later, computed tomography showed a mass at the right kidney near the hilar. Ureterorenoscopy and urine cytology were performed, and their results showed no evidence of malignancy. He had been followed closely without therapy. The mass increased in size during follow-up, and we reviewed the surgical specimen of the left ureteronephrectomy. Immunohistochemical studies revealed diffuse infiltration by IgG4 positive plasma cell. His serum IgG4 was high. We diagnosed him as IgG4-related kidney disease. In response to treatment with corticosteroid, the size of the tumor and serum IgG4 levels decreased. Most reported cases of IgG4-related disease involving kidney have a history of prior pancreatic involvement. We report a rare long term follow-up case of IgG4-related kidney disease without pancreatic involvement. PMID:24908817

    Introduction. Little is known about the effects of volume change by hemodialysis (HD) and mechanical stress caused by an anatomical structure being in contact with the left atrium on the progression of atrial remodeling. We experienced a case of atrial tachycardia (AT) in a patient who had left atrial (LA) scarring at the LA roof and a low-voltage area with slow conduction around the LA scar as components of AT circuit. Here, we present the conceivable hypothesis of the LA scar and the low-voltage area formation. Our concept can be useful in developing a strategy for ablation in a patient with chronic renal failure (CRF) on HD. Case Report. A 65-year-old man with CRF on HD was referred for AT ablation. Three-dimensional electroanatomical mapping revealed that the AT conducted around an LA scar in a counterclockwise fashion. There was a slow conduction area at the superior side of the LA scar, where the AT was terminated during the ablation. Computed tomography indicated a close relationship between the LA and the anatomical structures (ascending aorta and pulmonary artery). Conclusion. Volume change by HD and close contact of anatomical structures to the LA can promote atrial remodeling, resulting in AT occurrence. PMID:27148367

    Introducción: recientemente se han descrito nuevas entidades morfológicas de carcinomas de células renales (CCR) que influyen en el pronóstico. La estadificación clínica también ha sufrido modificaciones. El objetivo de este trabajo es conocer la prevalencia de los subtipos histológicos, el grado nuclear de Fuhrman y el estadio clínico del CCR. Métodos: estudio retrospectivo, descriptivo y comparativo de enero de 2008 a junio de 2013. Se analizaron 355 casos de CCR, fueron reclasificados de acuerdo con el grado nuclear y nuevos diagnósticos histopatológicos (clasificación de Vancouver) y estadificados de acuerdo con el TNM. Se realizó índice de Kappa para la concordancia diagnóstica y gradación nuclear, la asociación de variables cualitativas fue comparada con chi cuadrada. Resultados: el CCR claras convencional fue del 84.5 %, seguido del cromófobo y papilar. Otros subtipos menos frecuentes fueron: el carcinoma quístico multilocular, el CCR papilar de células claras y otros. El grado nuclear estuvo directamente relacionado con el tamaño tumoral y con el estadio clínico (p < 0.001). El estadio que predomino fue el pT1b N0 M0, seguido del pT3a N0 M0. Conclusiones: el tumor más frecuente fue el CCR claras, seguido del cromófobo y papilar. El grado nuclear, necrosis, áreas eosinófilas, sarcomatoides y rabdoides son factores pronósticos asociados a mayor agresividad y riesgo de metástasis.

    The majority of renal angiomyolipoma (AML) is sporadic and occasionally it occurs as part of tuberous sclerosis complex (TSC). Epithelioid AML (EAML), an uncommon variant, is considered potentially malignant based on anecdotal case reports. The prognostic significance of epithelioid component in an otherwise typical AML is uncertain. We studied 194 AMLs for the clinicopathologic features of epithelioid and TSC-associated AMLs. Epithelioid component was present in 15 cases (7.7%) with an average amount of 51% (range: 10% to 100%). Histologically, the epithelioid tumor cells were categorized into small, intermediate, and large cell type based on the cell size. Worrisome histologic features were seen in many EAMLs, including coagulative tumor necrosis in 27% (4/15), nuclear atypia in 93% (14/15), mitosis in 47% (7/15), and atypical mitosis in 1 case. All 15 EAML patients had a mean follow-up time of 5.1 years and none had local recurrence or distant metastasis. Sixteen (8.2%) AMLs occurred in patients with definitive TSC. Three histologic features, namely microscopic AML foci, epithelioid component, and epithelial cysts, were present in 10 (62.5%), 4 (25%), and 44% (7/16), respectively, of TSC-associated AMLs, compared with 11 (6.2%), 11 (6.2%), and 6 (3.4%), respectively, in non-TSC-associated AMLs (P value all <0.01). In summary, all 15 cases of EAMLs in our study had benign clinical outcomes despite adverse pathologic features. Epithelioid component, epithelial cysts, and microscopic AML foci are strongly associated with TSC and the presence of all 3 features should raise strong suspicion for TSC.

    Chronically increased echogenicity on renal ultrasound is a sensitive early finding of chronic kidney disease that can be detected before manifestation of other symptoms. Increased echogenicity, however, is not specific for a certain etiology of chronic kidney disease. Here, we performed whole exome sequencing in 79 consanguineous or familial cases of suspected nephronophthisis in order to determine the underlying molecular disease cause. In 50 cases, there was a causative mutation in a known monogenic disease gene. In 32 of these cases whole exome sequencing confirmed the diagnosis of a nephronophthisis-related ciliopathy. In 8 cases it revealed the diagnosis of a renal tubulopathy. The remaining 10 cases were identified as Alport syndrome (4), autosomal-recessive polycystic kidney disease (2), congenital anomalies of the kidney and urinary tract (3), and APECED syndrome (1). In 5 families, in whom mutations in known monogenic genes were excluded, we applied homozygosity mapping for variant filtering, and identified 5 novel candidate genes (RBM48, FAM186B, PIAS1, INCENP, and RCOR1) for renal ciliopathies. Thus, whole exome sequencing allows the detection of the causative mutation in 2/3 of affected individuals, thereby presenting the etiologic diagnosis and allows identification of novel candidate genes.

    Many law enforcement agencies around the United States are employing the use of TASER(®) electronic control devices (TASER(®) International Inc.) to subdue combative suspects. Since its inception the TASER(®) has had a temporal association with reports of rhabdomyolysis. Case reports have reported TASER(®) induced rhabdomyolysis as mild but serious cases have also been reported. Herein we present the case of a single patient who was admitted to our health network with severe rhabdomyolysis after receiving TASER(®) shocks and review the pertinent literature. No direct link has been established between clinically significant rhabdomyolysis and TASER(®) device application but this case serves as an example of a sparsely documented but serious complication that may occur in patients who are at risk for restraint by an electronic control device.

    The authors report the case of a 70-year-old woman who developed a Brown-Sequard-syndrome within 6 weeks caused by an intramedullary spinal cord metastasis of an occult renal cell carcinoma. Intramedullary metastases are rare and represent only 4-8.5% of central nervous system metastases. An important feature of intramedullary metastases is the rapid progression of neurological deficits which necessitates rapid treatment. There are only eight earlier reports of intramedullary metastasis due to renal cell carcinoma (Schiff D, O'Neill BP. Intramedullary spinal cord metastases: clinical features and treatment outcome.

    We will study the epidemiologic, clinical, biological, therapeutic, prognostic characteristics and predictive factors of development of nephropathy in ankylosing spondylitis patients. We retrospectively reviewed the medical record of 32 cases with renal involvement among 212 cases of ankylosing spondylitis followed in our service during the period spread out between 1978 and 2006. The renal involvement occurred in all patients a mean of 12 years after the clinical onset of the rheumatic disease. Thirty-two patients presented one or more signs of renal involvement: microscopic hematuria in 22 patients, proteinuria in 23 patients, nephrotic syndrome in 11 patients and decreased renal function in 24 patients (75%). Secondary renal amyloidosis (13 patients), which corresponds to a prevalence of 6,1% and tubulointerstitial nephropathy (7 patients) were the most common cause of renal involvement in ankylosing spondylitis followed by IgA nephropathy (4 patients). Seventeen patients evolved to the end stage renal disease after an average time of 29.8 ± 46 months. The average follow-up of the patients was 4,4 years. By comparing the 32 patients presenting a SPA and renal disease to 88 with SPA and without nephropathy, we detected the predictive factors of occurred of nephropathy: tobacco, intense inflammatory syndrome, sacroileite stage 3 or 4 and presence of column bamboo. The finding of 75% of the patients presented a renal failure at the time of the diagnosis of renal involvement suggests that evidence of renal abnormality involvement should be actively sought in this disease.

    Bacillary angiomatosis (BA) is a rare vasculoproliferative disorder due to Bartonella henselae (BH) or Bartonella quintana. It can involve many organs, including the skin, and has been mainly reported in patients with acquired immunodeficiency syndrome. In organ transplant recipients (OTR), this disorder remains misdiagnosed and therapeutic guidelines are nonexistent. We report 3 cases of BA with skin involvement in OTR and review similar cases from the literature. BA manifests on the skin with violaceous lesions mimicking Kaposi sarcoma, and is associated with fever, lymphadenopathy, and liver, spleen, or lung nodules. Bartonellosis infections in OTR are due to BH, the agent causing cat-scratch disease (CSD), but BA comprises histologically a prominent vascular proliferation, which is usually lacking in CSD. Cultures and serologic tests are poorly reliable for the diagnosis, which relies on demonstration of BH within the lesions. A history of cat exposure exists in most cases and pediatric OTR are at higher risk. Prevention consists of regular use of a flea-control product in cats and prompt cleaning of scratches. Our cases highlight several original features of this rare condition, which could potentially improve the management of BA in OTR.

    Laparoscopic manipulation of retroperitoneal organs is usually performed by the transperitoneal approach primarily because of the ease of access by way of the pneumoperitoneum. However, difficulty in adequately accessing structures that are surrounded by bowel, liver, spleen or postoperative adhesions makes this approach suboptimal in certain cases. We describe the use of the retroperitoneal laparoscopic approach to the upper pole of a kidney for marsupialization of a symptomatic, recurrent, complex renal cyst. An algorithm for current management of symptomatic renal cysts is discussed.

    We herein report the case of a patient with critical hyperkalemia after unilateral adrenalectomy (ADX) for aldosterone-producing adenomas, which were coexisting with primary hyperparathyroidism. A right adrenal tumor oversecreting mineral corticoid was identified in a 62-year-old female whose kidney function had been impaired due to primary hyperaldosteronism and hyperparathyroidism. The ADX improved her hypertension with normalization of the plasma aldosterone concentration, but without adequately increasing her plasma renin activity. Her eGFR further decreased postoperatively, hyperkalemia appeared and the serum potassium level rose to 6.3 mEq/L at 3 months after ADX. Then, treatment with calcium polystyrene sulfonate jelly was started. Eight months after ADX, a left lower parathyroidectomy was performed, and the serum calcium and intact parathyroid hormone levels decreased to the normal range. The hyperkalemia was difficult to control within 20 months postoperatively without treatment with calcium polystyrene sulfonate jelly or hydrocortisone. This suggests that unmasking the renal impairment and relative hypoaldosteronism after ADX might induce critical hyperkalemia.

    We describe the case of a 75-year-old man affected by a chronic obstructive pulmonary disease and chronic renal failure admitted to our emergency department for dyspnea and interscapular stabbing pain. Chest radiography showed diffuse parenchymal consolidation in the lower right lung with bronchiectasis, but the treatment for infection disease did not improve the clinical conditions of the patient. According to Wells score indicating an intermediate risk for pulmonary embolism, we performed a chest ultrasonography that showed ultrasonographic patterns of thromboembolism. Because the presence of chronic renal failure limited the execution of a helical computed tomographic pulmonary angiography, a pulmonary scintigraphy was performed confirming the diagnosis of pulmonary embolism. Our case suggested that chest ultrasonography can be a valuable tool for early detection of pulmonary embolism and to establish immediately an appropriate therapy.

    A 66-year-old male patient was referred to our hospital for bilateral renal pelvic tumors. Ureteroscopic biopsy revealed urothelial carcinoma (UC) of low grade (G1) of the renal pelvis. Renal sparing treatment with systemic chemotherapy and percutaneous tumor resection was performed. However, during subsequent follow up, a recurrent tumor was found on the left ureter. After ureteroscopic laser ablation of the tumor, Bacillus Calmette-Guerin (BCG) perfusion therapy (once a week, total 6 weeks) was performed via a single J ureteral catheter with no adverse events. Later, another recurrent recurrence was found on the right ureter, and was managed by ureteroscopic laser ablation followed by BCG perfusion therapy via a single J ureteral catheter. However, the patient developed high fever with chill from the day after initial BCG perfusion therapy on the right side. Although we started antibiotics, high fever continued. Then antituberculous drugs were administered and his condition was improved. Computed tomographic scan revealed a right renal mass 57 mm in diameter, which was consistent with tuberculous granuloma. The tuberculous granuloma persisted despite the continuation of anti-tuberculous drugs. In exceptional cases of upper tract UC such as single kidney and bilateral tumor, BCG perfusion therapy has been used as adjunctive treatment to cure or prevent UC. However, dosages and administration methods of BCG perfusion therapy for upper tract UC still remain to be standardized. Serious adverse events after BCG perfusion therapy require prompt and proper management including the use of anti-tuberculous drugs.

    Abstract The case of a 55-year-old man who attempted suicide by ingesting <100 mL of 28% sodium chlorite solution is presented. On arrival in the intensive care unit, the patient appeared cyanotic with lowered consciousness and displayed anuria and chocolate brown serum. Initial laboratory tests revealed 40% of methemoglobin. The formation of methemoglobin was effectively treated with methylene blue (10% after 29 hours). To remove the toxin, and because of the anuric acute renal failure, the patient received renal replacement therapy. Despite these therapeutic measures, the patient developed hemolytic anemia and disseminated intravascular coagulation, which were treated with red blood cell transfusion and intermittent hemodialysis. These interventions led to the improvement of his condition and the patient eventually fully recovered. Patient gave written informed consent. This is the third known case of chlorite poisoning that has been reported. Based upon this case, we suggest the management of sodium chlorite poisoning to comprise the early administration of methylene blue, in addition to renal replacement therapy and transfusion of red blood cells.

    Systemic necrotic and granulomatous vasculitis presents with vascular involvement in almost every organ, manifesting with stenosis, ischemia, infarction, or hemorrhage. The clinical picture depends on the kind and size of the involved vessels and on the activity of the inflammatory process. Wegener's granulomatosis is a necrotic, granulomatous inflammation of small vessels of the upper and lower airways and kidneys. We present the case of a 25-year-old male in whom the definitive diagnosis of Wegener's granulomatosis was achieved within five weeks from onset. Among the first symptoms were microinfarcts localized in the fingertips and the nail matrix; their nature was investigated with capillaroscopy. PMID:21427813

    Tumor lysis syndrome (TLS) is an oncologic emergency that is caused by massive tumor cell lysis. It is commonly associated with hematological cancers like leukemia and lymphoma and uncommonly with solid nonhematologic tumors as well. However, spontaneous tumor lysis syndrome (STLS) without any cytotoxic chemotherapy rarely occurs in solid tumors. We describe a case of STLS in a metastatic adenocarcinoma of unknown primary and review the literature of STLS in solid non-hematologic tumors to identify various risk factors for pathogenesis of this entity.

    Background High-cut-off hemodialysis (HCO-HD) can effectively reduce high concentrations of circulating serum free light chains (sFLC) in patients with dialysis-dependent acute kidney injury (AKI) due to multiple myeloma (MM). Therefore, the aim of this study was to analyze renal recovery in a retrospective single-center cohort of dialysis-dependent MM patients treated with either conventional HD (conv. HD) or HCO-HD. Methods and Results The final cohort consisted of 59 patients treated with HCO-HD (n = 42) or conv. HD (n = 17). A sustained sFLC response was detected in a significantly higher proportion of HCO-HD patients (83.3%) compared with conv. HD patients (29.4%; p = 0.007). The median duration of sFLC required to reach values <1000 mg/l was 14.5 days in the HCO-HD group and 36 days in the conv. HD group. The corresponding rates of renal recovery were 64.3% and 29.4%, respectively (chi-squared test, p = 0.014). Multivariate regression and decision tree analysis (recursive partitioning) revealed HCO-HD (adjusted odds ratio [OR] 6.1 [95% confidence interval (CI) 1.5–24.5], p = 0.011) and low initial uric acid values (adjusted OR 1.3 [95%CI 1.0–1.7], p = 0.045) as independent and paramount variables associated with a favorable renal outcome. Conclusions In summary, the results from this retrospective case-control study suggest in addition to novel agent-based chemotherapy a benefit of HCO-HD in sFLC removal and renal outcome in dialysis-dependent AKI secondary to MM. This finding was especially pertinent in patients with low initial uric acid values, resulting in a promising renal recovery rate of 71.9%. Further prospective studies are warranted. PMID:27152520

    Spontaneous regression of metastatic renal cell carcinoma (RCC) is rare, but well-documented in clear cell RCC. However, there are no reports on spontaneous regression of unclassified RCC. Since the radiological findings of pulmonary infarcts and inflammatory pseudotumors are similar to those of metastases from RCC, a definitive diagnosis is difficult without performing a histological examination. A 56-year-old woman underwent medical examination by a physician. An abdominal computed tomography (CT) scan revealed a 22-mm mass with a cystic area in the right kidney, as well as multiple enlarged lymph nodes in the common iliac, external iliac and groin areas, bilaterally. A chest CT revealed multiple pulmonary nodules bilaterally, the largest measuring 15 mm. Since the right renal tumor was suspected to be an RCC, laparoscopic partial nephrectomy was performed. The final pathological diagnosis of the renal tumor was unclassified RCC. One month following surgery, a CT scan revealed spontaneous regression of the pulmonary nodules. We herein present a rare case of spontaneous regression of pulmonary nodules in a patient with unclassified RCC following laparoscopic partial nephrectomy. To the best of our knowledge, this is the first case of spontaneous regression in unclassified RCC. PMID:27330764

    Multiple myeloma (MM) represents a rare form of post-transplantation lymphoproliferative disorder, and the presence of plasma cells in the liver is generally associated with aggressive forms of MM. In the present study, an unusual case of extramedullary plasmacytoma, affecting the liver and vertebrae of a recipient of a renal transplant, is reported. The patient had been previously treated with bortezomib for an MM following renal transplantation, as diagnosed by percutaneous needle biopsy of the hepatic lesion. He was then treated with 5 cycles of RCD regimen (lenalidomide, 25 mg, days 1–21; cyclophosphamide. 50–100 mg, days 1–21; and dexamethasone, 20 mg, days 1, 8, 15 and 22). The patient achieved partial clinical remission without any severe therapy-associated toxicity effects, indicating that lenalidomide is an effective and safe treatment for extramedullary liver plasmacytoma in renal recipients. In conclusion, the present case study indicated that the RCD regimen was effective and safe in the treatment of relapsed and refractory MM. PMID:26722266

    Abstract Acute renal failure due to ureter compression after a mesh-plug inguinal repair in a kidney transplant recipient has not been previously reported to our knowledge. A 62-year-old man, who successfully underwent kidney transplantation from a deceased donor 6 years earlier, was admitted for elective repair of a direct inguinal hernia. The patient underwent an open mesh-plug repair of the inguinal hernia with placement of a plug in the preperitoneal space. We did not observe the transplanted ureter and bladder during dissection of the inguinal canal. Immediately after surgery, the patient became anuric, and a graft sonography demonstrated massive hydronephrosis. The serum creatinine level increased rapidly, and the patient underwent an emergency reoperation 8 hours later. During surgery, we did not identify the ureter but, immediately after plug removal, urine output increased progressively. We completed the hernia repair using the standard technique, without plug interposition, and the postoperative course was uneventful with complete resolution of graft dysfunction 3 days later. Furthermore, we reviewed the clinical features of complications related to inguinal hernia surgery. An increased risk of urological complications was reported recently in patients with a previous prosthetic hernia repair undergoing kidney transplantation, mainly due to the mesh adhesion to surrounding structures, making the extraperitoneal dissection during the transplant surgery very challenging. Moreover, older male kidney transplant recipients undergoing an inguinal hernia repair may be at higher risk of graft dysfunction due to inguinal herniation of a transplanted ureter. Mesh-plug inguinal hernia repair is a safe surgical technique, but this unique case suggests that kidney transplant recipients with inguinal hernia may be at higher risk of serious urological complications. Surgeons must be aware of the graft and ureter position before proceeding with hernia repair. A prompt

    Pharmacokinetic parameters can be significantly altered for both extracorporeal life support (ECLS) and continuous renal replacement therapy (CRRT). This case report describes the pharmacokinetics of continuous-infusion meropenem in a patient on ECLS with concurrent CRRT. A 2.8-kg, 10-day-old, full-term neonate born via spontaneous vaginal delivery presented with hypothermia, lethargy, and a ~500-g weight loss from birth. She progressed to respiratory failure on hospital day 2 (HD 2) and developed sepsis, disseminated intravascular coagulation, and liver failure as a result of disseminated adenoviral infection. By HD 6, acute kidney injury was evident, with progressive fluid overload >1500 mL (+) for the admission. On HD 6 venoarterial ECLS was instituted for lung protection and fluid removal. On HD 7 she was initiated on CRRT. On HD 12, a blood culture returned positive and subsequently grew Pseudomonas aeruginosa with a minimum inhibitory concentration (MIC) for meropenem of 0.25 mg/L. She was started on vancomycin, meropenem, and amikacin. A meropenem bolus of 40 mg/kg was given, followed by a continuous infusion of 10 mg/kg/hr (240 mg/kg/day). On HD 15 (ECLS day 9) a meropenem serum concentration of 21 mcg/mL was obtained, corresponding to a clearance of 7.9 mL/kg/min. Repeat cultures from HDs 13 to 15 (ECLS days 7–9) were sterile. This meropenem regimen was successful in providing a target attainment of 100% for serum concentrations above the MIC for ≥40% of the dosing interval and was associated with a sterilization of blood in this complex patient on concurrent ECLS and CRRT circuits.

    Pharmacokinetic parameters can be significantly altered for both extracorporeal life support (ECLS) and continuous renal replacement therapy (CRRT). This case report describes the pharmacokinetics of continuous-infusion meropenem in a patient on ECLS with concurrent CRRT. A 2.8-kg, 10-day-old, full-term neonate born via spontaneous vaginal delivery presented with hypothermia, lethargy, and a ~500-g weight loss from birth. She progressed to respiratory failure on hospital day 2 (HD 2) and developed sepsis, disseminated intravascular coagulation, and liver failure as a result of disseminated adenoviral infection. By HD 6, acute kidney injury was evident, with progressive fluid overload >1500 mL (+) for the admission. On HD 6 venoarterial ECLS was instituted for lung protection and fluid removal. On HD 7 she was initiated on CRRT. On HD 12, a blood culture returned positive and subsequently grew Pseudomonas aeruginosa with a minimum inhibitory concentration (MIC) for meropenem of 0.25 mg/L.

    Acute renal failure due to ureter compression after a mesh-plug inguinal repair in a kidney transplant recipient has not been previously reported to our knowledge. A 62-year-old man, who successfully underwent kidney transplantation from a deceased donor 6 years earlier, was admitted for elective repair of a direct inguinal hernia. The patient underwent an open mesh-plug repair of the inguinal hernia with placement of a plug in the preperitoneal space. We did not observe the transplanted ureter and bladder during dissection of the inguinal canal. Immediately after surgery, the patient became anuric, and a graft sonography demonstrated massive hydronephrosis. The serum creatinine level increased rapidly, and the patient underwent an emergency reoperation 8 hours later. During surgery, we did not identify the ureter but, immediately after plug removal, urine output increased progressively. We completed the hernia repair using the standard technique, without plug interposition, and the postoperative course was uneventful with complete resolution of graft dysfunction 3 days later. Furthermore, we reviewed the clinical features of complications related to inguinal hernia surgery. An increased risk of urological complications was reported recently in patients with a previous prosthetic hernia repair undergoing kidney transplantation, mainly due to the mesh adhesion to surrounding structures, making the extraperitoneal dissection during the transplant surgery very challenging. Moreover, older male kidney transplant recipients undergoing an inguinal hernia repair may be at higher risk of graft dysfunction due to inguinal herniation of a transplanted ureter. Mesh-plug inguinal hernia repair is a safe surgical technique, but this unique case suggests that kidney transplant recipients with inguinal hernia may be at higher risk of serious urological complications. Surgeons must be aware of the graft and ureter position before proceeding with hernia repair. A prompt diagnosis

    Acute renal infarction presents in a similar clinical picture to that of a renal stone. We report a 55-year-old Saudi female, known to have atrial fibrillation secondary to mitral stenosis due to rheumatic heart disease. She presented with a two day history of right flank pain that was treated initially as a renal stone. Further investigations confirmed her as a case of renal infarction. Renal infarction is under-diagnosed because the similarity of its presentation to renal stone. Renal infarction should be considered in the differential diagnosis of loin pain, particularly in a patient with atrial fibrillation.

    Tertiary hyperparathyroidism (HPT) is a rare condition that affects patients with secondary HPT, which develop hyperplasia of the parathyroid glands, thus causing an increase in parathyroid hormone levels. Bone alterations are the main consequences of this condition including the development of osteolytic lesions called brown tumor. This article reports an unusual case of brown tumors located in the maxilla and mandible in a 19-year-old man with chronic renal failure with hyperplasia of the parathyroid glands. The lesions regressed approximately 5 months after the parathyroidectomy. At this same time, the patient underwent renal transplant. The patient was followed for 5 years, showing improvement in overall clinical status. There was also improvement of the results of laboratory tests and the pattern of trabecular bone. The correct diagnosis of oral lesions was of great relevance for the conservative treatment could have been chosen. PMID:27563621

    A 65-year-old patient, with a history of left hemi-thyroidectomy for adenomatous goiter 20 years previously, was found to have pulmonary lesions on chest X-ray, a brain lesion on computerized tomography (CT), and elevated serum thyroglobulin (Tg). While completion thyroidectomy revealed that no pathological evidence of thyroid malignancy, radioiodine-avid pulmonary, brain, and renal and bone lesions were identified on diagnostic as well as posttherapy whole body planar scintigraphy and single photon emission computed tomography-CT. Subsequent ultrasonography-guided biopsy of a renal nodule showed thyroid follicular cells. This case suggests that metastatic differentiated thyroid carcinoma should be suspected in asymptomatic patients with incidentally detected lesions, raised serum Tg, and history of thyroid lesions.

    The goal of this study is to evaluate the feasibility and efficacy of percutaneous transarterial embolization for the treatment of serious renal hemorrhage after renal biopsy. Nine patients with renal hemorrhage had frank pain and gross hematuria as main symptoms after renal biopsy. Intrarenal arterial injuries and perinephric hematoma were confirmed by angiography in all cases. The arterial injuries led to two types of renal hemorrhage, Type I: severe renal injure or intrarenal renal artery rupture (n=5), with contrast medium spilling out of the artery and spreading into renal pelvis or kidney capsule in angiography; Type II, pseudo aneurysm or potential risk of intrarenal artery injure (n=4), where contrast medium that spilled out of intraartery was retained in the parenchyma as little spots less than 5 mm in diameter in angiography. Transcatheter superselective intrarenal artery embolization was performed with coils or microcoils (Type I intrarenal artery injure) and polyvinyl alcohol particles (Type II injure). The intrarenal arterial injuries were occluded successfully in all patients. Light or mild back or abdominal pain in the side of the embolized kidney was found in three patients following embolization procedures and disappeared 3 days later. Serum creatinine and perinephric hematoma were stable, and gross hematuresis stopped immediately (n=4) or 3-5 days (n=3) after embolization. In conclusions, transcatheter superselective intrarenal artery embolization as a minimally invasive therapy is safe and effective for treatment of serious renal hemorrhage following percutaneous renal biopsy.

    Renal infarction is an uncommon condition that resulted from inadequate perfusion of the kidney and is easily missed diagnosed due to its nonspecific clinical presentations. Major risk factors for renal infarction are atrial fibrillation, previous embolism, and ischemic and valvular heart disease. Progressive decrease in renal function or even death can occur if renal infarction is not diagnosed accurately and promptly. Ketamine abuse may cause variable urinary tract injury. However, renal infarction caused by ketamine abuse has never been reported. To our knowledge, this is the first documented case of renal infarction following nasal insufflation of ketamine.

Therefore, a balanced compromise between optimal and affordable technology is required in order to reach the targets of achieving good medical care and meeting the expectations of patients, their families, healthcare providers, and society as a whole. Under these premises, and focusing on the aforementioned targets, we believe that on-line hemodiafiltration (HDF) represents the most advanced and clinically appropriate RRT modality available to best cope with the CKD epidemic. Together with the guidance and recommendations of those taking care of CKD patients on dialysis therapy, the contribution of industry is indispensable for the availability of highly reliable and affordable solutions to the impending dilemma. As representatives of the academic-medical community and of industry, we present a joint case for the application of on-line HDF towards meeting the challenge of large-scale provision of dialysis under an increasingly restrictive financial climate.

He was detected to have new onset diabetes mellitus together with hepatitis C virus (HCV) infection (genotype 1). His HCV load remained high despite the change of immuno-suppression from tacrolimus to cyclosporine. A decision to treat with a new anti-viral combination of ledipasvir and sofosbuvir for 12 weeks was taken. Within 3 weeks, his raised serum transaminases levels normalized and viral load became undetectable. At the end of 16 weeks, he continues to do well with normal renal function, has sustained remission from hepatitis C infection and resolution of diabetes.

    Primary carcinoma of the renal calyx is extremely rare. The present study reported nephron sparing endoscopic treatment for primary carcinoma of the renal calyx. An 81-year-old female presented with a 1-year history of intermittent painless gross hematuria. Computed tomography and X-ray of the urinary tract were unable to definitively identify any lesion. Flexible ureteroscopic examination revealed a tumor with epicenter in the lower calyx of the right kidney, with additional involvement around the calyx. Biopsies were obtained and pathology revealed low-grade urothelial carcinoma. Considering additional co-morbidities, the patient elected to undergo endoscopic management with thulium laser. The present report described the feasibility of flexible ureteroscopic thulium laser resection for the treatment of renal calyx carcinoma. PMID:27330785

    Background: Primary infection with BK virus (BKV) is occurred during childhood and usually asymptomatic, but after initial infection, BKV may persist lifelong in the kidney and genitourinary tract. Reactivation may occur in individuals with compromised immunity such as renal transplant recipients. Due to the role of BKV in BK virus-associated nephropathy (BKVAN) and potentially renal allograft rejection, the detection of BKV in renal transplant candidates is very important. The aim of this study was to evaluate the frequency of BK viremia in end stage renal disease cases who were candidates for renal transplantation. Methods: In this cross-sectional study, 50 cases with end stage renal disease who were candidates for renal transplantation were recruited from the main dialysis unit in Tehran, Iran. Presence of BK viremia was determined in plasma samples of cases using real time PCR. Results: A total of 50 renal transplant candidates with mean age 37.8±13 yr were enrolled in the study. Fifty two percent of subjects were male. Forty six (92%) of them were under HD and 4 (8%) were on PD. BK virus was not detected in any plasma samples of renal transplant candidates. Conclusion: This study showed absence of BK viremia in our renal transplant candidates. However, due to the important role of BKV in BKVAN and renal graft failure and rejection, further studies involving larger number of cases are required to elucidate the rate of the BKV in renal transplant candidates.

    The management of renal stones needs a recent and good quality imaging. Contrast medium injection is optional. Extracorporeal shockwave lithotripsy (ESWL) is the most common treatment of renal stones. ESWL is indicated as first line treatment for less than 1.5cm stones. The stone-free (SF) rate at 3 months of ESWL is 70-80%. Results of ESWL for stones with more than 1000UH density or located in the lower calyx are poor. Flexible ureteroscopy (URS) is indicated in case of ESWL failure or for hyperdense, 1-2cm stones. The SF rate of flexible is 80%. Percutaneous nephrolithotomy is indicated for complex or more than 2cm stones. Asymptomatic and non infected stones, especially if located in the lower calyx, do not need urological treatment but must be followed up. In all cases, renal stones needs a metabolic evaluation and treatment, and annual follow-up.

    Standard care for patients with renal failure while in an intensive care unit involves traditional hemodialysis or peritoneal dialysis and protein restriction. We present a case of a patient with renal failure supported with continuous arteriovenous hemofiltration with dialysis (CAVH-D) who was given full protein alimentation. Total daily urea clearance was measured from the CAVH-D output. Protein load was 196 +/- 34 g/day while receiving total parenteral nutrition and 164 +/- 30 g/day while receiving enteral alimentation. Serum blood urea nitrogen was controlled between 40 and 75 mg/dL, except during septic episodes. Nitrogen balance was estimated based upon known alimentation protein load and measurable and estimated nitrogenous losses. The patient was potentially in nitrogen equilibrium during most of the dialysis period. The cumulative nitrogen balance was positive by 5.2 g after 67 days of dialysis. Volume of alimentation was 3.49 +/- 0.7 liters/day. With CAVH-D, the renal failure patient can receive full alimentation without volume or protein load limitations. Furthermore, nitrogen balances can be estimated easily while the patient is on CAVH-D.

    Bacillus Calmette-Guèrin (BCG) is commonly used not only as an infant vaccination, but also as a treatment of and prophylaxis to prevent recurrence in the management of non-muscle-invasive bladder cancer. However, the use of "live" BCG is sometimes complicated by associated infection. We present a case study of a 77-year-old man who developed bilateral renal masses after intravesical BCG therapy was initiated in November 2013, following transurethral resection of non-muscle-invasive bladder cancer. After four courses of BCG (Japan strain, 80 mg per treatment) instillations, a computed tomography examination for febrile episodes showed multiple bilateral renal masses, accompanied by a histological finding of a granulomatous reaction. An acid fast bacterium was cultured from only urine among blood, urine, and microscopic samples. Using the cultured strain, BCG infection was confirmed by the specific gene deletion pattern based on allele-specific polymerase chain reaction analysis. Anti-tuberculosis treatment, including isoniazid (300 mg/day), rifampicin (600 mg/day), and ethambutol (1,000 mg/day), was started for the BCG-related renal granuloma in February 2014. After 3 months, antibiotic therapy was discontinued owing to severe appetite loss, though the masses remained solid. No rapid growth has been detected after anti-BCG therapy. Intravesical BCG therapy is recommended worldwide as one of standard treatments for non-muscle-invasive bladder cancer. We should closely observe patients undergoing this approach for emerging BCG complications.

    INTRODUCTION: Total hip replacement is generally proposed for renal transplant patients with avascular osteonecrosis of the femoral head. PURPOSE: The purpose of the study is to report the long-term outcome after rehabilitation of bilateral total hip arthroplasty in a patient with renal transplantation suffering from avascular osteonecrosis of the both femoral heads. MATERIAL AND METHOD: The patient S.D, 49 years old at follow-up. Few months after renal transplantation, the patient had got avascular osteonecrosis of both femoral head. One year after transplantation the total hip arthroplasty for both hip joints were performed. Three years later repeat total hip arthroplasty surgery for left hip was performed. After any surgery intervention the patient was referred for inpatient rehabilitation. For clinical assessment the clinical findings and Harris Hip Score have been used. The rehabilitation program consisted of exercises, occupational therapy, and patient education. RESULTS: After any rehabilitation treatment the patient had improvement of clinical findings. At follow-up assessment outcome for both hip function was good - Harris Hip Score was 81 points. CONCLUSION: Rehabilitation is integral part of multidisciplinary treatment of renal transplant recipient after total hip arthroplasty. Regular exercise training of these patients is very important for improving of their long-term outcome. PMID:27275350

  6. [The focal renal lesions].

    PubMed

    Tuma, Jan

    2013-06-01

    The focal renal lesions are altogether common. Most frequently are found Columna Bertini hypertrophies (so called pseudotumors) and simple renal cysts. The role of sonography in the practice is to distinguish pseudotumors from real renal tumors, and simple renal cysts from complex cysts. The differentiation of complex renal cysts is possible with the help of the CEUS (= contrast enhanced ultrasound) and other imaging modalities such as CT or MRI. In these cases, the CEUS imaging agent has clear advantages over CT and MRI, because it is composed of gas bubbles, which are only slightly smaller than red blood cells and remains exclusively intravascularly while the CT and MRI contrast agents diffuse into the interstitial space without any real perfusion. The real tumors can be differentiated from certain focal non-tumorous changes based on the ultrasound and clinic. The further differentiation of individual kidney tumors and metastases using ultrasound, MRI, CT and CEUS is only partly possible. In all uncertain or unclear cases, therefore, an open or ultrasound-guided biopsy is useful.

    Renal calyx carcinoma (RCXC) may mimic collecting duct carcinoma (CDC) or urothelial carcinoma (UC) of the renal pelvis. RCXC is distinguished from CDC and UC of the renal pelvis as having the tumor epicenter in the renal calyx, with limited involvement of the surrounding renal pelvis surface urothelium. In this study, we summarize our experience with this entity. Ten cases of RCXC, including 9 cases with urothelial differentiation (RCXC-UC) and 1 case with salivary gland-type differentiation (RCXC-SC), were identified. Ten consecutive cases of UC were selected for comparison, with extensive renal pelvis involvement and with secondary renal parenchymal invasion. Two cases of collecting duct carcinoma (CDC) were also examined. Immunohistochemistry (IHC) was performed on representative tissue blocks for PAX8, PAX2, CK5, CK7, CK20, p63, GATA3, AMACR, RCC, CD10, vimentin, S100, and MSA. The 10 cases of RCXC (M:F=4:6, ages: 62-91 years, mean: 76) presented with renal masses of 3-6cm. Ureteroscopic studies and renal pelvic washings showed atypical/malignant cells in three cases. Seven patients were treated with nephrectomy followed by radiation±chemotherapy, and all cases developed metastases to lymph nodes or liver/lung/bone. In all 7 cases with nephrectomy, there was extensive renal parenchymal involvement with infiltrating borders and diffuse spread along collecting ducts. Six RCXC-UC contained focal squamous differentiation. The RCXC-SC displayed features of adenoid cystic and basaloid features. In situ UC, with or without papillary components, was identified in the calyces in all 7 nephrectomy cases with remaining renal pelvis harboring small tumor burden in 5 cases, and no tumor in another 2 cases. Of the three cases without nephrectomy, no tumor in the renal pelvis could be visualized with endoscopy, however one case was associated with UC of the urinary bladder. Of 10 control UC cases, tumor was limited to the tip of renal papilla in 7 cases, extensive in 3

    Hydronephrosis is a common finding in urinary tract outflow obstruction. Chronically obstructed hydronephrotic system may be associated with parenchymal changes. Ultrasound, intravenous urography, micturating cysto-urethrogram and scintigraphy are commonly performed to evaluate the cause of obstruction. In childhood, pelviureteric junction obstruction is a common cause of the hydronephrosis. Hydronephrosis can also be present in horseshoe kidneys due to poor drainage. However, a large sized hydronephrotic cavity may obscure the finding of horseshoe kidney. A case was reported, and it was diagnosed as horseshoe kidney on follow-up renal dynamic scan and confirmed with the help of dimercaptosuccinic acid SPECT/CT.

    Tenofovir disoproxil fumarate (TDF) is widely used in HIV-infected patients. It is associated with tubular toxicity, but its management is controversial. A possible strategy is to switch to a dual therapy based on lamivudine or emtricitabine (XTC) and protease inhibitors (PIs). A case-control study was designed to evaluate the switch to XTC + PI therapy in patients with TDF-related renal toxicity. A case was defined as a patient who was on TDF/XTC + PI and who switched to XTC + PI. A control was defined as a patient with the same clinical features who remained on TDF/XTC + PI. Twenty-one cases and 21 controls were included. After 48 weeks, no differences in efficacy were observed. No improvement in the glomerular filtration rate as estimated with the Cockroft-Gault formula (eGFR) was seen, but the number of times that patients had values below 60 ml/min was higher with standard TDF/XTC 1 PI treatment than with dual XTC + PI treatment. A switch to dual therapy could be an option for patients at risk of TDF-related renal damage with no relevant risk of virological or immunological failure.

    Between 1967 and 1977, 395 consecutive cases of glomerulonephritis (GN) were collected by a Copenhagen study group. The diagnosis was established by histological and biochemical criteria. Light microscopy investigations of thin silver-stained sections were applied. In a follow-up in 1980 all cases were categorized by one of the following end points: death without uremia, uremia, recovery, or censored cases. The course is presented in figures showing the cumulated distribution of outcomes in relation to observation time. Each histological subgroup of GN had its own characteristic course with respect to initial rates of changes in the renal state, as well as to frequency of recovery, uremia and death. The prognosis was good in minimal changes GN and proliferative GN, bad in unclassified GN and worst in extracapillary GN. When part of a connective tissue disease, GN carried a poor prognosis. We conclude that histological classification of GN based on light microscopy offers a reliable means of predicting the long-term prognosis.

    Rickets/osteomalacia is an important problem in a tropical country. Many cases are due to poor vitamin D intake or calcium deficient diets and can be corrected by administration of calcium and vitamin D. However, some cases are refractory to vitamin D therapy and are related to renal defects. These include rickets of renal tubular acidosis (RTA), hypophosphatemic rickets, and vitamin D dependent rickets (VDDR). The latter is due to impaired action of 1α-hydroxylase in renal tubule. These varieties need proper diagnosis and specific treatment. PMID:24251212

    IgG4-related disease is a recently recognized clinical entity. It is characterized by diffuse organ swelling or mass formation, a dense lymphoplasmacytic infiltrate rich in IgG4-positive plasma cells with fibrosis and typically an increased serum IgG4 concentration, which may affect various organs. An 80-year-old woman with an otherwise unremarkable previous medical history was revealed to have a renal mass that was indicative of renal malignant carcinoma, for which a radical nephrectomy was performed. The mass was diagnosed as an IgG4-related inflammatory pseudotumor, which was histopathologically confirmed. The patient is currently well without evidence of IgG4-related disease at 3 months post-surgery, and did not require any additional therapy. PMID:27123131

    End-stage renal failure (ESRD) is an important public health issue, because of both the increasing number of patients requiring renal replacement therapy and the cost of treatment. The need for a reliable data system, capable of describing the patient care network as a whole, including dialysis or transplantation, has often been reiterated. The Direction Générale de la Santé (the French Department of Health) commissioned INSERM (the National Institute of Health and Medical Research) to "study the feasibility of different scenarios of data collection about ESRD patient care in order to meet the priority needs of health care administration, physicians, and researchers". Analysis of these needs allowed the goals to be defined: to provide an accurate picture of ESRD patient care in order to guide and evaluate health care policy, to inform clinicians, and to provide a tool for more focused special studies in renal research issues. Three scenarios were studied: the first would use data systems of both the government and the National Health Insurance system for planning health care services, upon EfG (The French Transplant Agency) network to evaluate transplantation, and upon a few regional registries for epidemiology and research; the second is based on repeated cross-sectional surveys; the third would rely upon the organization of an information system, the Renal Epidemiology and Information Network (REIN). Regional centers and a national coordinating office would register and follow-up ESRD patients, principally to evaluate health care supply and quality. The REIN database would also be a resource for research. The advantage of the first scenario is its low cost; its principal drawback is that evaluations will not be possible in the regions without registries. The second suggestion is inadequate. The last project would fulfil the goals that were defined. The REIN data system would be a true public health project of interest to all the participants and institutions

    In patients with renal artery stenosis (RAS), the inhibition of renin-angiotensin-aldosterone system can cause deterioration of renal function. Here we present a 75-year-old man who developed acute renal failure after olmesartan treatment. Following discontinuation of olmesartan, his renal functions normalized. His renal Doppler ultrasonography and renal angiography showed findings consistent with bilateral RAS. In this case, unlike those previously reported, renal failure developed with olmesartan for the first time and after only a single dose, which is thought to be a new, safe, and tolerable antihypertensive agent. This is a well-defined effect of angiotensin-converting enzyme inhibitors, in patients with RAS. Also with the increasing use of angiotensin II receptor blockers (ARBs), renal failure associated with ARBs in patients with RAS is rising. The use of olmesartan also requires caution and close follow-up of renal functions for patients who have risk factors. PMID:20863218

    Angioimmunoblastic T-cell lymphoma is one of the most common subtypes of peripheral T-cell lymphoma (15-20% of all cases), accounting for approximately 1-2% of all non-Hodgkin lymphomas. It often presents autoimmune phenomena including hemolytic anemia, thrombocytopenia, glomerulonephrities and circulating immune complexes. Polyarteritis nodosa is an autoimmune disease characterized by necrotizing vasculitis of medium vessels, which rarely develops in association with hematological malignant disorders. Herein we report the case of a 40-year-old man who underwent lymph node biopsy in the suspicious of sarcoidosis. On the basis of histological and immunohistochemical findings, the diagnosis of angioimmunoblastic T-cell lymphoma was performed. The patient was successfully treated with cytarabine-based regimen for 6 cycles. Three months after the initial diagnosis of angioimmunoblastic T-cell lymphoma, a whole body computed tomography showed a lesion in the lower pole of the left kidney. Renal cell carcinoma was suspected, thus a nephrectomy was carried out. The histological findings were compatible with polyarteritis nodosa. To the best of our knowledge, the association between polyarteritis nodosa and angioimmunoblastic T-cell lymphoma has been described only once. This relation may be secondary to the induction of an autoimmune phenomenon by the lymphoma with the formation of circulating immune complexes, leading to vessels walls injury. A careful evaluation is needed in the management of angioimmunoblastic T-cell lymphoma patients with signs of renal failure in order to avoid delay of treatment and organ damage.

    Renal cell carcinomas (RCCs) harboring the t(6;11)(p21;q12) translocation were first described in 2001 and recently recognized by the 2013 International Society of Urological Pathology Vancouver Classification of Renal Neoplasia. Although these RCCs are known to label for melanocytic markers HMB45 and Melan A and the cysteine protease cathepsin K by immunohistochemistry (IHC), a comprehensive IHC profile has not been reported. We report 10 new t(6;11) RCCs, all confirmed by break-apart TFEB fluorescence in situ hybridization. A tissue microarray containing 6 of these cases and 7 other previously reported t(6;11) RCCs was constructed and immunolabeled for 21 different antigens. Additional whole sections of t(6;11) RCC were labeled with selected IHC markers. t(6;11) RCC labeled diffusely and consistently for cathepsin K and Melan A (13 of 13 cases) and almost always at least focally for HMB45 (12 of 13 cases). They labeled frequently for PAX8 (14 of 23 cases), CD117 (10 of 14 cases), and vimentin (9 of 13 cases). A majority of cases labeled at least focally for cytokeratin Cam5.2 (8 of 13 cases) and CD10 and RCC marker antigen (10 of 14 cases each). In contrast to a prior study's findings, only a minority of cases labeled for Ksp-cadherin (3 of 19 cases). The median H score (product of intensity score and percentage labeling) for phosphorylated S6, a marker of mTOR pathway activation, was 101, which is high relative to most other RCC subtypes. In summary, IHC labeling for PAX8, Cam5.2, CD10, and RCC marker antigen supports classification of the t(6;11) RCC as carcinomas despite frequent negativity for broad-spectrum cytokeratins and EMA. Labeling for PAX8 distinguishes the t(6;11) RCC from epithelioid angiomyolipoma, which otherwise shares a similar immunoprofile. CD117 labeling is more frequent in the t(6;11) RCC compared with the related Xp11 translocation RCC. Increased pS6 expression suggests a possible molecular target for the uncommon t(6;11) RCCs that

    Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory vascular disease that most commonly affects the renal and extracranial carotid arteries. We present 3 cases of renal infarction complicating renal artery FMD in 42-, 43-, and 46-year-old females and provide a comprehensive review of the literature on this topic. In our patients, oral anticoagulation therapy was used to treat all cases of infarction, and percutaneous angioplasty was used nonemergently in one case to treat refractory hypertension. All patients remained stable at 1-year follow-up. This is consistent with outcomes in previously published reports where conservative medical management was comparable to surgical and interventional therapies. Demographic differences may also exist in patients with renal infarction and FMD. A higher prevalence of males and a younger age at presentation have been found in these patients when compared to the general population with FMD.

    Spontaneous renal artery dissection (SRAD) is a rare entity, which often presents diagnostic difficulties because of its non-specific clinical presentation. We report six cases complicated with renal infarction, occurring in middle-aged male patients without risk factors, illustrating the difficulty and delay for diagnosing SRAD. Ultrasound and Doppler imaging were not sensitive enough to confirm the diagnosis, and contrast-enhanced abdominal computed tomography was used to correct the diagnosis and allow the clinicians to propose appropriate treatment. We conclude that considering the urgency in diagnosing and treating SRAD, contrast enhanced abdominal tomography and/or abdominal magnetic resonance imaging should be proposed as soon as a suspicion of SRAD is evoked by the clinical presentation.

    We present the sonographic findings of fetal renal vein thrombosis in a series of 6 patients. The mean gestational age at diagnosis was 31.2 weeks. Four cases were unilateral, and 2 were bilateral. The most common findings were renal enlargement and intrarenal vascular calcifications, followed by increased renal parenchymal echogenicity. Inferior vena cava thrombosis was found in 4 patients and common iliac vein thrombosis in 2. Fetal renal vein thrombosis is an uncommon diagnosis with characteristic sonographic findings. The presence of these findings should prompt Doppler interrogation of the renal vein and inferior vena cava to confirm the diagnosis.

    The coexistence of nephrotic syndrome and renal vein thrombosis has been of medical interest since Rayer’s description in 1840. Renal vein thrombosis has been underdiagnosed because of its variable clinical and radiological findings but it becomes a more frequently recognizable clinical entity since diagnosis can be easily established by modern angiographic techniques. Generally it has been believed that renal vein thrombosis may cause nephrotic syndrome. But recent articles strongly suggest that renal vein thrombosis is a complication of the nephrotic syndrome rather than a cause. We report three cases of nephrotic syndrome associated with renal vein thrombosis. PMID:3154812

    Background and Objectives: Renal cysts have a high prevalence in the general population, and their estimated incidence increases with age. Renal cyst aspiration (usually with sclerotherapy) or open/laparoscopic decortication is a generally effective and safe method in the treatment of symptomatic simple renal cysts. The success rates of laparoscopic decortication and percutaneous aspiration-sclerotherapy were compared to assist in the decision making for the procedure. Methods: A total of 184 patients with symptomatic simple renal cysts were treated with either laparoscopic decortication in 149 cases or percutaneous aspiration-sclerotherapy in 35 cases. The follow-up period was approximately 35 months, and the symptomatic and radiologic success rates of the 2 techniques were compared retrospectively. Results: Laparoscopic decortication was found to have high success rates, a low recurrence rate, and minimal morbidity. Percutaneous aspiration-sclerotherapy is an outpatient procedure with a minimally higher recurrence rate. Conclusion: When a symptomatic cyst is encountered and treatment of the cyst is indicated, laparoscopic decortication is a more efficient method that offers better results than percutaneous aspiration-sclerotherapy.

    Atherosclerotic renal artery disease represents a cause of which little is known but not a cause to be neglected for hypertension and renal insufficiency. Even though its occurrence remains badly defined, atherosclerotic renal artery disease is constantly on the rise due to the aging population, the never prevailing hypertension and diabetes mellitus. This review aims to give a clinical profile of patients presenting with atherosclerotic renal artery disease and to discuss, in the light of study results, which diagnostic evaluation should be used considering the sequence and the benefit and risk of each in order to initiate a personalized treatment. Patients affected by atherosclerotic renal artery disease are likely to have more complications and more extensive target-organ damage than patients without renal artery stenosis. The evolution of the atherosclerotic renal artery disease is in general slow and progressive. Nevertheless, certain clinical cases manifest themselves with the onset of acute renal failure bought upon by the administration of blockers of the rennin-angiotensin-aldosterone system, or by some other causes responsible for a sudden drop in renal plasma flow (e.g., thrombosis of the renal artery). The relationship between atherosclerotic renal artery disease and atherosclerosis is complex, and mediators implicated in the pathophysiology of renovascular disease may also contribute to the progression of cardiovascular damage. An early assumption of the atherosclerotic renal artery stenosis is warranted to determine the adapted treatment (i.e., medical treatment, revascularisation...) just as the assumption and the correction of the more general cardiovascular risk factors.

However, the kidney itself is not a regenerative organ, as all the nephrons are formed during embryonic development. Here, we will investigate advances in the molecular genetics of renal organogenesis, including what this can tell us about lineage relationships, and discuss how this may serve to inform us about both the normal processes of renal repair and options for regenerative therapies.

    IgG4-related tubulointerstitial nephritis (IgG4-TIN) is the most common renal manifestation of IgG4-related kidney disease (IgG4-RKD) and may cause acute or chronic renal dysfunction. Imaging often shows heterogeneous densities in the kidneys, such as a mass or multiple nodules. Serology usually demonstrates high levels of serum IgG4 and total IgG. Most patients have other organs involvement by IgG4 related disease. Although lymphadenopathy is frequently observed in patients with IgG4-TIN, it is rarely presented as the only extrarenal lesion. Herein, we present a rare case of IgG4-TIN associated with only lymphadenopathy and without elevated serum IgG4 or renal imaging abnormalities. A 61-year-old Chinese man was admitted to our hospital with seven months history of generalized lymphadenopathy and five months history of renal dysfunction. His renal imaging was normal. He had no current or previous clinical, radiographic, and/or histologic evidence of other organ involvement except for the lymphadenopathy. Renal biopsy indicated plasma cell-rich TIN with an increased number of IgG4-positive plasma cells and storiform fibrosis. Repeated lymph nodes biopsy revealed IgG4-related lymphadenopathy. However, he did not have elevated serum IgG4 or total IgG levels. Oral prednisone therapy improved his renal function and lymphadenopathy. These findings supported our final diagnosis of IgG4-TIN. Clinicians should be aware of this condition and steroid therapy should be considered for such patients. An early diagnosis and appropriate therapy can induce remission and preserve renal function.

A 32-year-old man had a history of end stage renal disease and received regular hemodialysis treatment for more than 5 years. He was admitted in our service for total functional impotence of the right lower limb with knee pain after a common fall two months ago. The radiogram showed a ''patella baja" with suprapatellar calcifications. The ultrasound and MRI showed an aspect of rupture of the quadriceps tendon in its proximal end with retraction of 3 cm. Quadriceps tendon repair was performed with a lengthening plasty, and the result was satisfactory after a serial rehabilitation program. The diagnosis of quadriceps tendon ruptures needs more attention in patients with predisposing diseases. They should not be unknown because the treatment of neglected lesions is more difficult. We insist on the early surgical repair associated with early rehabilitation that can guarantee recovery of good active extension.

    PVN is a well-known cause of renal allograft dysfunction and failure. The diagnosis is established by examination of tissue from the renal graft, and confirmed by immunohistochemical or in situ hybridization techniques. Electron microscopy can be utilized as an ancillary modality to identify the viral particles ultrastructurally. The tubular epithelial cells are the primary target of PV cytopathic effect; however, PV-associated glomerular changes have also been described. Immune-type electron-dense deposits in the TBMs have been described in the setting of PVN, and rarely, likewise have glomerular subepithelial hump-like deposits. Diffuse immune-mediated proliferative glomerulonephritis in the setting of PVN has not been reported before. In this report, we describe an 11-yr-old kidney transplant recipient boy who developed immune-mediated glomerulonephritis with light microscopic, immunofluorescence, and ultrastructural features compatible with acute PIGN superimposing chronic PVN, discuss this unusual association and the possible mechanisms of antigen clearance in PVN and present a literature review.

    In spite of recent advances in perioperative management, the risk of neurosurgical intervention for patients with chronic renal failure is still considered too high. In this study, coil embolization for incidental aneurysms in such patients is demonstrated in reference to midterm results. A 42-year-old woman with a history of hemodialisis for 7 years presented with subcortical hemorrhage in her right frontal lobe. The magnetic resonance angiography (MRA) demonstrated a distal anterior cerebral artery aneurysm, but it was considered to be unrelated to the hemorrhage. Two and a half months after the hemorrhage the aneurysm was embolized with interlocking detachable coils. Thirty months after embolization, the angiogram revealed the coil compaction and the recanalization of the aneurysm neck. However, 54 months after embolization, the figure of the embolized aneurysm and neck remnant was the same as the previous findings. A 69-year-old woman with a history of hemodialisis for 5 years suddenly experienced left hemiparesis. Computed tomography revealed cerebral infarction in the right frontoparietal white matter. In addition, a left middle cerebral artery aneurysm was unexpectedly found on the MRA. Five months after the onset of the attack, the aneurysm was embolized with a Guglielmi detachable coli. An angiogram obtained 24 months after the embolization showed the aneurysm to be almost completely obliterated. In considering the therapeutic risks and benefits for incidental aneurysms of patients with chronic renal failure, intra-vascular surgery could be recommended as a less invasive treatment.

    We report a case of reflex anuria after transarterial embolization of a renal tumor. Anuria developed immediately after embolization and resolved 74 hr following the procedure. We postulate that reflux anuria in our case was related to mechanoreceptors, chemoreceptors, or both, as these are stimulated by the occluded blood vessels, ischemia, and edema of the normal renal tissue of an embolized kidney.

    We describe the first case of a psoas muscle abscess caused by Nocardia beijingensis and subcutaneous phaeohyphomycosis caused by Phaeoacremonium parasiticum in a renal transplant recipient. The patient was treated for nocardiosis with percutaneous drainage and intravenous trimethoprim/sulfamethoxazole (TMP/SMX) combined with imipenem for 2 weeks, followed by a 4-week course of intravenous TMP/SMX and then oral TMP/SMX. During hospitalization for the psoas muscle abscess the patient developed cellulitis with subcutaneous nodules of his right leg. Skin biopsy and cultures revealed a dematiaceous mold, subsequently identified as P. parasiticum by DNA sequencing. The subcutaneous phaeohyphomycosis was treated with surgical drainage and liposomal amphotericin B for 4 weeks followed by a combination of itraconazole and terbinafine. The patient gradually improved and was discharged home after 18 weeks of hospitalization. PMID:26867363

    We report a case of long-term complete response of multiple lung metastases of renal cell carcinoma (RCC) by the combination therapy with interferon alpha (IFN alpha) and UFT. A 38 year-old man having left RCC with lung metastases underwent radical left nephrectomy and extended lymph node dissection, the pathological stage being pT2N2. Although metastatic lung tumors increased in size and number against intravenously admitted interferon gamma (IFN gamma) therapy after the surgery, they completely disappeared following the subsequent combination therapy with intramuscularly admitted interferon alpha (IFN alpha) and oral intake of UFT in about 2 years. The patient has been disease-free for 5 years after cessation of the treatment. Combination therapy with IFN alpha and UFT might be more effective on metastases of RCC than single use of IFN alpha or IFN gamma.

    Mucinous tubular and spindle cell carcinoma (MTSC) was first recognized as a specific entity in the World Health Organization 2004 classification. The "classic" tumor presentation includes an extracellular blue-gray mucinous/myxoid matrix accompanying the typical tubular and spindle cell epithelial components. Tubules are lined by cuboidal to columnar cells with bland nuclei, central small to medium sized nucleoli, and few to no mitoses. By expanding the histologic spectrum, a number of studies highlighted the distinction between MTSC and solid variant of papillary renal cell carcinoma (sPRCC), although controversy still exists. Here, we evaluated two cases of MTSC and compared two cases of sPRCC by light microscopy, special staining, immunohistochemical staining and fluorescence in situ hybridization (FISH). We found that morphologic and immunophenotyping features showed more overlap between MTSC and sPRCC. In addition, gains of chromosomes 7 and 17 and loss of Y, which are characteristic of PRCC, were observed in two cases of sPRCC and one case of MTSC, suggesting that MTSC is similar to sPRCC or may be a subtype of PRCC.

    Thyroid-like follicular carcinoma of the kidney (TLFCK) is a provisional new entity of renal cell carcinoma (RCC). We herein reported and compared one TLFCK case and one PRCC case with thyroid-like feature. The former entirely consisted of thyroid-like follicular architecture and the tumor cells were diffusely positive for PAX-8, but negative for CK7, AMACR, and CD10. By contrast, both papillary architecture (~60%) and thyroid-like follicular architecture (~40%) were identified in the latter. Tumor cells in both histological components exhibited diffusely positive staining for PAX-8, CK7, AMACR, but negative for CD10. FISH analysis showed no aberration in TLFCK case but trisomy of chromosome 17 in PRCC case. Along with a brief literature review, we presented that recognition of TLFCK is important to distinguish it from other conditions that show thyroid-like features. Additionally, a diagnosis of TLFCK should be cautiously made when papillary component is present in the tumor. PMID:26663803

    Septic arthritis (SA) typically occurs in young children, often from Staphylococcus. With chronic immunosuppression, however, pathogens may be atypical. A 15-year-old African-American female developed Mycoplasma hominis SA in her right hip 2 months following cadaveric renal transplant (Tx). Her presentation was subtle and indolent, without fever or leukocytosis. Although reported in adult Tx recipients, M. hominis infections have not been described in pediatric recipients. Early immunosuppression (basiliximab, prednisone, tacrolimus, mycophenolate mofetil and Thymoglobulin) may have increased her susceptibility to M. hominis. Optimal therapy for M. hominis SA is not well established and relapses occur. This patient underwent joint incision and drainage, treatment for 8 weeks with doxycycline and levofloxacin guided by in vitro sensitivities, and a reduction in immunosuppression. She has been free of ongoing infection for 3 years with stable graft function (Cr 1.1 mg/dL) on moderate immunosuppression with prednisone, tacrolimus and MMF.

    A 75-year-old male undergoing hemodialysis because of diabetic nephropathy was referred to our hospital complaining of high fever and swelling of the left kidney. Our initial clinical diagnosis was severe pyelonephritis. He was initially treated with intravenous antibiotics and his clinical symptoms subsequently improved but only temporarily. The high fever soon recurred, accompanied by progressive thrombocytopenia. His general condition deteriorated despite conservative treatment. He then underwent nephrectomy of the left kidney. However, the thrombocytopenia persisted and his general condition did not improve. The pathological diagnosis was malignant lymphoma (non-Hodgkin's lymphoma, diffuse large B-cell type). He received chemotherapy, but his status rapidly deteriorated and he died 1.5 months after the operation. Primary renal malignant lymphoma is very rare, because the kidney lacks lymphatic tissue.

    Generally, patients with renal cell carcinoma (RCC) are viewed as potential candidates for antiangiogenic targeted therapy. Tubulocystic RCC (TCRC) is a recently described entity which may behave aggressively, and the rationale for antiangiogenic therapy in this group of renal tumors has yet to be determined. Seven TCRCs and five non-tumor tissue samples from seven patients were subjected to relative expression analysis of mRNA levels of 16 genes involved in three angiogenic signal pathways: (1) VHL/HIF, (2) RTK/mitogen-activated protein kinase (MAPK), and (3) PI3K/Akt/mTOR. Two of them, pathways (2) and (3), are often targeted by antiangiogenic agents. We also determined the mutation and methylation status of the VHL gene. Finally, the levels of vascular endothelial growth factor A (VEGFA), HIF-1α, HIF-2α proteins, and phosphorylated mTOR protein were also determined. The comparison of tumor and control samples revealed no changes of mRNA levels of the following genes: VHL, HIF-1α, HIF-2α, PTEN, Akt2, Akt3, mTOR, VEGFA, KDR, HRas, C-Jun, EGFR, and FGF2. Significantly elevated mRNA level of TP53 was found, while the mRNA levels of FLT1 and C-FOS were reduced in tumor samples. No mutations or methylation in the VHL gene were found. Changes in levels of studied proteins VEGFA, HIF-1α, HIF-2α, and increased phosphorylation of mTOR protein were not found. Three studied angiogenic pathways (VHL/HIF, RTK/MAPK, and PI3K/Akt/mTOR) seem not to be upregulated in TCRC samples, so there appears to be no rationale for a general recommendation of antiangiogenic targeted therapeutic protocols for patients with these tumors.

    Il cancro del rene rappresenta la 13a forma di tumore a livello mondiale e risulta incrementata, dal punto di vista epidemiologico, di circa il 2% annuo nelle ultime due decadi. Studi recenti hanno mostrato un numero complessivo di 65,150 nuovi casi di cancro renale diagnosticato nei paesi occidentali e circa 13.680 morti. Il carcinoma a cellule renali rappresenta approssimativamente il 90% di tutte le forme di cancro renale e presenta un tasso di mortalità di circa 4 soggetti ogni 100000 abitanti per anno. Il carcinoma a cellule renali ha, spesso, un particolare corteo sintomatologico caratterizzato da dolore addominale, masse addominali ed ematuria. Caratteristico è il fatto che circa il 25-30% dei pazienti, all’atto della diagnosi, presentano già metastasti a distanza; un ulteriore 30-50%, inoltre, svilupperanno metastasi nel corso della malattia, anche dopo molti anni dall’operazione chirurgica di nefrectomia radicale. Il Cancro del Rene a Cellule Chiare metastatizza in genere per via linfatica, ematogena, transperitoneale o per invasione diretta, ed i siti di metastasi più comuni sono il polmone ed i linfonodi, seguiti dalle ossa e dal fegato. Tra tutte le possibili localizzazioni ai segmenti addominali, il duodeno rappresenta la sede meno colpita: quando coinvolta, viene, in genere, invasa la regione periampollare ed il bulbo del duodeno. Tali localizzazioni danno segno di sè, spesso tardivamente, con sanguinamenti (ematemesi) o ostruzioni del tratto gastrointestinale superiore (vomito). Il nostro caso clinico descrive un carcinoma a cellule renali che si presentava, dopo soli 5 mesi dalla nefrectomia radicale destra, con sanguinamento del tratto gastrointestinale superiore e metastasi a carico del duodeno, e che è stato trattato chirurgicamente con duodenocefalopancreasectomia. L’intervento chirurgico, noto per essere altamente demolitivo ed associato ad elevata morbilità, applicato a recidiva precoce di cancro, ha garantito un ottimo risultato

    Seventy-two patients with severe falciparum malaria are described. Twenty-four (33.3%) were complicated by acute renal failure. Comparing patients with renal failure and those without, statistically significant differences occurred regarding presence of cerebral malaria (83% vs 46%), jaundice (92% vs 33%), and death (54% vs 17%). A significantly higher number of patients with renal failure were nonimmune visitors to malaria endemic regions. Renal failure was oliguric in 45% of cases. Dialysis was indicated in 38%, 29% died in early renal failure, and 33% recovered spontaneously. It is concluded that falciparum malaria is frequently complicated by cerebral malaria and renal failure. As nonimmune individuals are prone to develop serious complications, malaria prophylaxis and vigorous treatment of cases is mandatory. PMID:2236718

    Multilocular cystic renal cell carcinoma (MCRCC) is a rare presentation of renal cell carcinoma. Most patients are asymptomatic and frequently MCRCCs are detected incidentally. MCRCCs have good prognosis because of their low malignant potential. We report a case of a 39-year-old woman who presented with mild right flank pain and normal laboratory data. On imaging examinations, a Bosniak III cystic lesion was detected in the lower third of the right kidney. She underwent right partial nephrectomy and histopathology showed a multilocular cystic renal cell carcinoma Fuhrman grade 1. In this article, we also present a review of the literature on MCRCC, highlight the correlation of the pathological and imaging characteristics of these low aggressive renal lesions, and underscore the importance of their recognition to prevent unnecessary radical surgery.

    Hip fracture is a common occurrence in the elderly. Due to the growing demand for the specific care of these patients, we established the Orthogeriatric Unit (OGU) at San Gerardo University Hospital (Italy) in 2007. However, simultaneous bilateral femoral neck fractures among the geriatric population (those aged ≥65 years) are rarely reported in the literature. Reporting the rare case of a frail 76-year-old woman admitted with bilateral hip fracture and end-stage renal disease, we explain the important role played by the OGU and its flexible multidisciplinary approach for providing comprehensive care to patients with multimorbidity and clinical complexity. The team of geriatricians, orthopedic surgeons, anesthesiologists, and, in this case, a nephrologist, helped in the careful planning and timing of the single-step surgical repair, decided the appropriate type of anesthesia, and optimized outcomes. After a prompt evaluation of the patient, the OGU approach can achieve clinical stabilization prior to intervention. Along with a strict follow-up in the postoperative phase, this could result in a significant reduction of complications and mortality rates and an early start to a tailored rehabilitation process. We strongly suggest employing facilities with multidisciplinary teams for cases involving complex patients at short-term high risk for poor clinical outcomes. Indeed, the usual single-specialist model of care is gradually being abandoned worldwide.

    Background Pre-existing non-neoplastic renal diseases or lesions may influence patient renal function after tumor removal. However, its description is often neglected or omitted in pathologic reports. To determine the incidence and clinical significance of non-neoplastic lesions, we retrospectively examined renal tissues obtained during 85 radical nephrectomies for renal cell carcinoma. Methods One paraffin-embedded tissue block from each case containing a sufficient amount of non-tumorous renal parenchyma was cut and processed with hematoxylin and eosin and periodic acid-Schiff methods. Non-neoplastic lesions of each histological compartment were semi-quantitatively and quantitatively evaluated. Results Among the various histologic lesions found, tubular atrophy, arterial intimal thickening, and glomerulosclerosis were the most common (94.1%, 91.8%, and 88.2%, respectively). Glomerulosclerosis correlated with estimated glomerular filtration rate at the time of surgery, as well as at 1- and 5-years post-surgery (p=.0071), but tubulointerstitial fibrosis or arterial fibrous intimal thickening did not. Post-hoc analysis revealed that glomerulosclerosis of more than 20% predicted post-operative renal function. However, its significance disappeared when gender and age were considered. Conclusions In conclusion, non-neoplastic lesions, especially with regard to glomerulosclerosis percentage, should be described in pathology reports to provide additional information on renal function decline.

    A patient who was operated for an abdominal aortic aneurysm 7 years earlier presented with recently discovered iliac and renal artery aneurysms. The renal artery had an angulation of 90{sup o}, but the aneurysm was successfully excluded using a covered vascular stent graft placed over an extrastiff guidewire. Even in cases of complex anatomy of a renal aneurysm, endovascular treatment should be considered. With development of more flexible and low-profile endoprosthesis with accurate deployment, these have become more usable.

    2013-01-01

    Background The increasing incidence and prevalence of chronic kidney disease is an important challenge for health systems around the world. Access for care of the disease in Ethiopia is extremely limited. The main purpose of the study was to investigate survival pattern and assess risk factors for poor outcome of patients on maintenance hemodialysis for end stage renal disease in Ethiopia. Methods Medical records of patients on maintenance hemodialysis for end stage renal disease at Saint Gabriel General Hospital between 2002 and 2010 were reviewed. The data was collected by complete review of patient’s clinical data. Descriptive statistics was used for most variables and Chi-square test, where necessary, was used to test the association among various variables. Kaplan-Meier survival analysis was done to assess both short and long term survival. P-values of < 0.05 were considered as statistically significant. Results A total of 190 patients were registered for hemodialysis at the hospital 91 of which were included in the final assessment. Mean age at dialysis initiation was 58 ± 15 years. Fifty-five (60.4%) of the patients had prior history of diabetes. Almost all of them had serum creatinine of > 5mg/dl and some degree of anemia at dialysis initiation. Forty-one (45.1%) deaths occurred during dialysis treatment and 21 (23.1%) of patients died within the first 90 days of starting dialysis. Only 42.1% of them survived longer than a year. The frequently registered causes of death were septicemia (34.1%) and cardiovascular diseases (29.3%). Use of catheter as vascular access was associated with decreased short term and long term survival. Conclusion Dialysis as treatment modality is extremely scarce in Ethiopia and affordable to only the rich. Survival pattern in those on the treatment is less satisfactory and short of usual standards in the developed world and needs further investigation. We thus recommend a large scale analysis of national dialysis

    Fungal infection is relatively common among renal transplant recipients from developing countries. Mucormycosis, also known as zygomycosis, is one of the most serious fungal infections in these patients. The most common of presentation is rhino-cerebral. Isolated involvement of a renal allograft is very rare. A thorough search of literature and our medical records yielded a total of 24 cases with mucormycosis of the transplanted kidney. There was an association with cytomegalovirus (CMV) infection and anti-rejection treatment in these patients and most of these transplants were performed in the developing countries from unrelated donors. The outcome was very poor with an early mortality in 13 (54.5%) patients. Renal allograft mucormycosis is a relatively rare and potentially fatal complication following renal transplantation. Early diagnosis, graft nephrectomy and appropriate antifungal therapy may result in an improved prognosis for these patients.

    Angiomyolipoma with epithelial cysts (AMLEC) is a distinctive variant of angiomyolipoma characterized by grossly apparent epithelial cysts and a cellular, müllerian-like subepithelial stroma. Some authors suspect that the epithelial cysts mainly represent dilated entrapped native renal collecting duct epithelium, while other authors think that they represented true epithelial differentiation of the AML. Recently, it has been reported that obvious immunolabeling of melanocytic markers such as Melan A and HMB45, which are often immunolabeled in classical angiomyolipoma, are present in epithelial cysts in cases of AMLEC. Here, we report the case of a 43-year-old Japanese woman with AMLEC, and attempt to elucidate the significance of melanocytic marker immunolabeling in the cyst's epithelium. In the present case, Melan A was labeled in the cyst's epithelium, and was thought to reflect its labeling in renal tubules existing in the renal parenchyma outside the tumor. This finding may indicate that the cyst epithelium is derived from entrapped renal tubules inside the AML. Non-immunolabeling of the estrogen and progesterone receptors in the cyst epithelium may also suggest that the cyst epithelium is not neoplastic, in contrast to their labeling in neoplastic cells existing in cyst wall. Further examination, such as molecular analysis, is needed to determine whether these epithelial cysts is neoplastic or non-neoplastic.

    Viral infections are an important complication of transplantation. Polyomavirus are the commonest viruses that infect the renal allograft. Herpes virus nephropathy has also been described. In the past 15 years, adenovirus nephritis has emerged as a potentially life-threatening disease in renal transplant patients in developed countries. Most of the papers devoted to adenovirus nephritis are reported cases. The fate of such patients in resources-limited countries is not known. Herein, we describe the clinical, biological and prognostic findings of a black African transplanted patient with adenoviral hemorrhagic cystitis. This case is the very first of its kind reported in black Africa in a setting of a start of a renal transplantation pilot project. The patient is a 54-year-old man admitted at the nephrology service for gross haematuria and fever occurred 1 month after kidney transplantation. The diagnosis of adenoviral hemorrhagic cystitis has been suspected because the patient has displayed recurrent conjunctivitis and gastroenteritis well before transplantation, which was then confirmed by the real-time polymerase chain reaction performed on the blood. Conservatory measures associated with immunosuppression reduction have permitted the discontinuation of haematuria. This case has been discussed in regard of the epidemiology, the diagnosis, the treatment, the evolution and the prognosis of the adenoviral infection in the renal transplant patient. A review of the literature has been performed subsequently.

    Two college students who developed reversible acute deterioration in renal function following binge drinking of beer and the use of nonsteroidal antiinflammatory drugs (NSAIDs) are reported. Both patients presented with back and flank pain with muscle tenderness, but showed no evidence of overt rhabdomyolysis. The first case had marked renal failure, with a peak serum creatinine reaching 575 mumol/L (6.5 mg/dL), and acute tubular necrosis was documented by renal biopsy. The second case had only modest elevation in serum creatinine, and renal function rapidly improved on rehydration. The contribution of the potential muscle damage associated with alcohol ingestion to the changes in renal function in these two cases is not clear. However, the major mechanism for the acute renal failure was thought to be related to inhibition of renal prostaglandin synthesis in the face of compromised renal hemodynamics secondary to alcohol-induced volume depletion.

    We present a cohort of 8 renal carcinomas that displayed a variable (5%-95% extent) light microscopic appearance of renal angiomyoadenomatous tumor/clear cell papillary renal cell carcinoma (RAT/CCPRCC) without fulfilling the criteria for these tumors. All but 1 case predominantly (75%-95% extent) showed histopathologic features of conventional clear cell renal cell carcinoma. In 5 of 7 cases with mostly conventional clear renal cell carcinoma (CRCC) morphology, a diagnosis of CRCC was supported by the molecular genetic findings (presence of von Hippel-Lindau tumor suppressor [VHL] mutation and/or VHL promoter methylation and/or loss of heterozygosity [LOH] for 3p). Of the other 2 cases with predominantly characteristic CRCC morphology, 1 tumor did not reveal any VHL mutation, VHL promoter methylation, or LOH for 3p, and both chromosomes 7 and 17 were disomic, whereas the other tumor displayed polysomy for chromosomes 7 and 17 and no VHL mutation, VHL promoter methylation, or LOH for 3p. One tumor was composed primarily (95%) of distinctly RAT/CCPRCC-like morphology, and this tumor harbored a VHL mutation and displayed polysomy for chromosomes 7 and 17. Of the 5 cases with both histomorphologic features and molecular genetic findings of CRCC, we detected significant immunoreactivity for α-methylacyl-CoA racemase in 2 cases and strong diffuse immunopositivity for cytokeratin 7 in 3 cases. Despite the combination of positivity for α-methylacyl-CoA racemase and cytokeratin 7 in 2 cases, there was nothing to suggest of the possibility of a conventional papillary renal cell carcinoma with a predominance of clear cells.

  3. The case for dosing dabigatran: how tailoring dose to patient renal function, weight and age could improve the benefit–risk ratio

    Dabigatran is increasingly being used in clinical practice for the thromboprophylaxis in atrial fibrillation as a convenient therapy that needs no drug level monitoring. However, analysis of the data of the same clinical trial that led to the adoption of dabigatran in fixed-dosing regimens has indicated a small subgroup of patients that could be either over-treated, risking bleeding, or under-treated, risking embolism. Additional post-marketing data lends support to the favorable therapeutic profile of dabigatran but at the same time raises doubts about patient characteristics such as weight, age, renal function and their pharmacokinetic effects that, in some cases, could be serious enough to expose a minority of patients to risk. We will present a clinical case of a patient with an ischemic stroke while on dabigatran that was found with low dabigatran plasma levels and we will discuss the currently available data on the effects of inherent patient characteristics on dabigatran pharmacokinetics, the clinical impact of dabigatran plasma levels on safety and efficacy as well as the possibility of improving the risk–benefit profile of this agent by tailoring the dose for selected patient groups.

    It is known that many medical adverse events can be caused by nonsteroidal anti-inflammatory drugs (NSAIDs); however, epidemiologic evidence has not granted an affirmative relationship between NSAID use and the risk of end-stage renal disease (ESRD). We aimed to investigate the relationship in a Chinese population between short-term NSAID use and development of ESRD requiring chronic dialysis. A retrospective case-crossover design was used in this study. Using the Taiwanese National Health Insurance database, we identified 109,400 incident chronic ESRD patients with dialysis initiation from 1998 to 2009. For each patient, we defined the case period as 1 to 14 days and the control period as 105 to 118 days, respectively, before the first dialysis date. The washout period was 90 days between the case and control period. Detailed information about NSAID use was compared between the case and control periods. We calculated odds ratios (ORs) and their 95% confidence intervals (CIs) using a conditional logistic regression model. NSAID use was found to be a significant risk factor associated with dialysis commencement. The adjusted OR was 2.73 (95% CI: 2.62-2.84) for nonselective NSAIDs and 2.17 (95% CI: 1.83-2.57) for celecoxib. The OR reached 3.05 for the use of acetic acid derivatives. Compared with the oral forms, significantly higher risks were seen in parenteral NSAID use (OR: 8.66, 95% CI: 6.12-20.19). NSAIDs should be prescribed with caution, especially for those in ESRD high-risk groups.

    Tubulocystic renal cell carcinoma (TCRC) is a rare renal tumor. Patients are usually asymptomatic; it is usually detected incidentally, during imaging studies for Bosniak type III and type IV renal cysts. These tumors rarely metastasize. The role of targeted therapy in such rare tumors is still controversial. We report a case of TCRC initially presented as a Bosniak type II renal cyst and was discovered ultimately to be a metastatic disease. This type of presentation might broaden our understanding of this rare disease. PMID:27601972

    Between 1990 and 1993, we studied 14 cases of acute renal failure due to prolonged muscular exercise (e.g., squat jumping, sit-ups) and blunt trauma inflicted by law enforcement personnel using sticks or leather belts. None of the patients had a prior history of myopathy, neuropathy, or renal disease. All were critically ill and required renal support in the form of dialysis. Although the morbidity was high, 13 of the patients recovered normal renal function. One patient expired due to sepsis.

    The common sites of breast cancer metastases include bones, lung, brain, and liver. Renal metastasis from the breast is rare. We report a case of breast cancer metastatic to the kidney with extension into the renal vein. A 40-year-old woman had undergone left mastectomy for breast cancer at the age of 38. A gastric tumor, which was later proved to be metastasis from breast cancer, was detected by endoscopy. Computed tomography performed for further examination of the gastric tumor revealed a large left renal tumor with extension into the left renal vein. It mimicked a primary renal tumor. Percutaneous biopsy of the renal tumor confirmed metastasis from breast cancer. Surgical intervention of the stomach and the kidney was avoided, and she was treated with systemic chemotherapy. Breast cancer metastatic to the kidney may present a solitary renal mass with extension into the renal vein, which mimics a primary renal tumor.

    The histological evaluation of the renal parenchyma is often essential in cases of several renal diseases and provides useful information in determining the prognosis and guiding treatment. In patients with contraindications to percutaneous kidney biopsy, retroperitoneal laparoendoscopic single-site surgery (LESS) is to be preferred as a minimally invasive technique. However, there are cases in which the LESS technique is difficult to perform, especially given that the learning curve is not optimal. We present a case of a Jehovah's Witness patient with severe obesity, in whom conventional retroperitoneal laparoscopic renal biopsy was preferred to the LESS technique. PMID:25198939

    Renal artery stenosis, mainly due to fibromuscular dysplasia, is the second more common cause of arterial hypertension in children, after aortic coarctation. Two children sent to our Center of Pediatric Cardiology, one for arterial hypertension and the other for renal failure (associated with severe hypertension not previously recognized) are reported. In both of them the diagnosis of renal artery stenosis was established at Doppler ultrasonography, performed at the time of Doppler echocardiography. Both children were submitted to successful percutaneous transluminal angioplasty; short- and medium-term results are evaluated by Doppler ultrasonography. Renovascular disease is a potentially curable cause of renal artery stenosis in children. Renal artery evaluation by Doppler ultrasound is recommended in all hypertensive children who undergo Doppler echocardiography. PMID:15471155

    Percutaneous transluminal renal angioplasty/stenting (PTRAS) is frequently used to treat renal artery stenosis and renovascular disease (RVD); however, renal function is restored in less than one half of the cases. This study was designed to test a novel intervention that could refine PTRAS and enhance renal recovery in RVD. Renal function was quantified in pigs after 6 weeks of chronic RVD (induced by unilateral renal artery stenosis), established renal damage, and hypertension. Pigs with RVD then underwent PTRAS and were randomized into three groups: placebo (RVD+PTRAS), chronic endothelin-A receptor (ET-A) blockade (RVD+PTRAS+ET-A), and chronic dual ET-A/B blockade (RVD+PTRAS+ET-A/B) for 4 weeks. Renal function was again evaluated after treatments, and then, ex vivo studies were performed on the stented kidney. PTRAS resolved renal stenosis, attenuated hypertension, and improved renal function but did not resolve renal microvascular rarefaction, remodeling, or renal fibrosis. ET-A blocker therapy after PTRAS significantly improved hypertension, microvascular rarefaction, and renal injury and led to greater recovery of renal function. Conversely, combined ET-A/B blockade therapy blunted the therapeutic effects of PTRAS alone or PTRAS followed by ET-A blockade. These data suggest that ET-A receptor blockade therapy could serve as a coadjuvant intervention to enhance the outcomes of PTRAS in RVD. These results also suggest that ET-B receptors are important for renal function in RVD and may contribute to recovery after PTRAS. Using clinically available compounds and techniques, our results could contribute to both refinement and design of new therapeutic strategies in chronic RVD.

    A 30-year-old woman was referred to our hospital due to high blood pressure, dizziness, headache and blurred vision. She had past history of preeclampsia and gestational hypertension 4 years ago but she had not taken antihypertensive medication in spite of remained hypertension after delivery. She was hospitalized for fever due to urinary tract infection and severe hypertension which was above 210/140 mmHg. Despite maximal medical treatment with telmisartan 80 mg, nifedipine 120 mg, carvedilol 50 mg, doxazocin 8 mg, chlorthalidone 50 mg, spironolactone 50 mg#2, isosorbide dinitrate 80 mg and intermittent intravenous administration of nicardipine and labetalol, her systolic blood pressure remained above 160 mmHg and repeatedly measured above 200 mmHg. Her blood pressure was even refractory to combination of isosorbide dinitrate and sildenafil. Repeated evaluation for secondary cause of hypertension was negative. White coat effect was ruled out by repeated ambulatory blood pressure monitoring. Due to the blood pressure being uncontrolled over the next 3 months, renal denervation was carried out without any significant improvement in her blood pressure. She was referred to another tertiary hospital for a second opinion and suprapubic cystostomy was performed because neurogenic bladder was considered as a possible cause for the refractory hypertension. However, it failed to control the blood pressure. Three months later redo renal denervation was performed but its effect did not last for two days. She was referred to the department of anesthesiology and pain center to determine whether or not celiac plexus block would be effective in reducing the blood pressure. Initially, a temporary celiac plexus block was performed with local anesthetics. Two hours after procedure, blood pressure declined to 110/60 mmHg which was sustained for three days. Based on the efficacy of celiac plexus block, permanent celiac plexus block was perfomed using dehydrated alcohol and

    Background: Evaluation of renal vascular variations is important in renal donors to avoid vascular complications during surgery. Venous variations, mainly resulting from the errors of the embryological development, are frequently observed. Aim: This retrospective cross-sectional study aimed to investigate the renal vascular variants with multidetector computed tomography (MDCT) angiography to provide valuable information for surgery and its correlations with surgical findings. Materials and Methods: A total of 200 patients underwent MDCT angiography as a routine work up for live renal donors. The number, course, and drainage patterns of the renal veins were retrospectively observed from the scans. Anomalies of renal veins and inferior vena cava (IVC) were recorded and classified. Multiplanar reformations (MPRs), maximum intensity projections, and volume rendering were used for analysis. The results obtained were correlated surgically. Results: In the present study, out of 200 healthy donors, the standard pattern of drainage of renal veins was observed in only 67% of donors on the right side and 92% of donors on the left side. Supernumerary renal veins in the form of dual and triple renal veins were seen on the right side in about 32.5% of donors (dual right renal veins in 30.5% cases and triple right renal veins in 2.5% cases). Variations on the left side were classified into four groups: supernumerary, retro-aortic, circumaortic, and plexiform left renal veins in 1%, 2.5%, 4%, 0.5%, cases respectively. Conclusions: Developmental variations in renal veins can be easily detected on computed tomography scan, which can go unnoticed and can pose a fatal threat during major surgeries such as donor nephrectomies in otherwise healthy donors if undiagnosed.

    Renal cell carcinoma is usually seen in the native kidney but may be seen in the renal allograft. We report a rare case of renal cell carcinoma in a 56-year-old renal allograft recipient who was transplanted for end-stage renal disease induced by analgesic nephropathy. This complication developed after 13 years of renal transplantation. Patient was investigated for hematuria and abdominal pain with a normal renal function. Computed tomography depicted a mass sized 9.0×7.3×6.8 cm that involved the upper pole of the transplant. There was no metastasis. The patient underwent radical allograft nephrectomy for the carcinoma that had extended up to the renal hilum. Histopathological examination revealed Furhman grade-1, clear cell variant, stage pT2 N0 M0. In the last visit, the patient was on maintenance hemodialysis via arterio-venous fistula and planned for cadaveric renal transplantation. Computed tomography could facilitate early diagnosis and proper management of patients with post-renal allograft renal cell carcinoma. PMID:26889374
