Ethylene Vinyl Alcohol Copolymer Embolization for Acute Renal Hemorrhage: Initial Experience in 24 Cases.

The purpose of this study was to assess the efficacy and safety of ethylene vinyl alcohol (EVOH) copolymer (Onyx, Medtronic) for embolization for acute renal hemorrhage. Between October 2006 and June 2018, 24 consecutive patients were treated by embolization with EVOH copolymer for acute renal hemorrhage at Hôpital Bichat-Claude-Bernard. CT angiography was performed in all patients before treatment.

Daily Green Tea Infusions in Hypercalciuric Renal Stone Patients: No Evidence for Increased Stone Risk Factors or Oxalate-Dependent Stones.

Green tea is widely used as a ''healthy'' beverage due to its high level of antioxidant polyphenol compounds. However tea is also known to contain significant amount of oxalate. The objective was to determine, in a cross-sectional observational study among a population of 273 hypercalciuric stone-formers referred to our center for metabolic evaluation, whether daily green tea drinkers ( = 41) experienced increased stone risk factors (especially for oxalate) compared to non-drinkers.

Demographics and characterization of 10,282 Randall plaque-related kidney stones: a new epidemic?

Renal stone incidence has progressively increased in industrialized countries, but the implication of Randall plaque in this epidemic remains unknown. Our objectives were to determine whether the prevalence of Randall plaque-related stones increased during the past decades after having analyzed 30,149 intact stones containing mainly calcium oxalate since 1989 (cross-sectional study), and to identify determinants associated with Randall plaque-related stones in patients (case-control study). The proportion of Randall plaque-related stones was assessed over 3 time periods: 1989-1991, 1999-2001, and 2009-2011.

Pyonephrosis Caused by Salmonella Typhi: A Case Report.

Introduction: Salmonella is a rare cause of urinary tract infections. We report here a unique case of pyonephrosis due to Salmonella Typhi (S. Typhi) complication, a stone-related obstructive pyelonephritis.

Retrograde Approach to a Diverticular Kidney Stone through a Vesicoureteral Cohen's Reimplantation: A Novel Surgical Technique.

Cohen's technique is the standard treatment of vesicoureteral reflux in children. Its disadvantage is still the classic difficulty in subsequent retrograde ureteral access, requiring the use of percutaneous techniques in the treatment of kidney stones. We describe a novel surgical technique for retrograde catheterization of an adult ureter by a flexible ureterorenoscope, thereby facilitating the treatment of a symptomatic diverticular kidney stone.

Rapidly progressive kidney failure induced by fungal mycelia obstructing indwelling ureteral stents.

Antibiotics reduce the commensal flora in the gut, thereby facilitating the overgrowth of undesirable microorganisms such as Candida albicans. Here, we report the case of a 48-year-old woman with a history of obstructive uropathy consecutive to a radiation therapy, in whom both indwelling ureteral stents were rapidly occluded by fungal mycelia, resulting in a rapidly progressive kidney failure. Ascendant infection by C albicans had occurred after a 2- week course of antibiotics, prescribed for a perforative peritonitis also due to radiation-induced colitis.

[Bladder perforation during transurethral resection of bladder tumour: a review].

Transurethral resection of bladder tumour is a common procedure (10,711 new cases of bladder tumour diagnosed in France in 2000), associated with a certain morbidity. Intra- or extraperitoneal perforation of the bladder wall is a possible complication. The diagnosis is generally established intraoperatively and cystography can be performed in the operating room to demonstrate the diameter of the perforation.

[Infertility and testicular seminoma].

Introduction: Infertility in men may be associated with an elevated risk of testicular cancer. The authors report a case of testicular seminoma discovered fortuitously during a workup for infertility.

Case: A 30 year-old male was seen for infertility.

Upper urinary tract transitional cell carcinoma: recurrence rate after percutaneous endoscopic resection.

Objectives: To assess oncologic outcomes in patients undergoing percutaneous management for upper urinary tract transitional cell carcinoma (UUT-TCC) of the renal cavities.

Methods: We performed a retrospective review of data for patients who underwent percutaneous conservative surgery for a UUT-TCC between 1989 and 2005: sex; age at diagnosis; mode of diagnosis; smoking; history of bladder cancer; type of surgery; complications; tumour site, size, stage and grade, and recurrence and progression. We evaluated recurrence and survival rates.

Late metastasis of renal cell carcinoma to the submaxillary gland 10 years after radical nephrectomy.

Renal cell carcinoma metastasis to the submaxillary gland after tumor nephrectomy has not been previously recorded in the literature. Most reported cases have involved the parotid gland. We report in this article the first case of solitary submaxillary gland metastasis from clear cell renal cell carcinoma in an 83-year-old man who presented 10 years after primary treatment.

Laparoscopic excision of seminal vesicle cyst revealed by obstruction urinary symptoms.

Primary diseases of the seminal vesicle are rare. Most seminal vesicle cysts are congenital, and two-thirds are associated with renal dysplasia or agenesis and ectopic ureter opening into the seminal vesicle. Acquired cysts may be due to genitourinary infections, surgical prostate resection or ejaculatory duct lithiasis.

Nephron-sparing surgery for de novo renal cell carcinoma in allograft kidneys.

Renal cell carcinomas account for 4.6% of post-transplant cancers, 10% of which occur in allograft kidneys. We report three such cases among kidney grafts that were performed or followed from 1970 to 2004.

[Spontaneous renal haematoma: diagnostic and therapeutic approach in 7 cases].

Objective: Spontaneous renal haematomas are rare. The authors discuss the aetiological diagnosis and management of these haematomas.

Material And Methods: Seven cases (3 females and 4 males) of spontaneous renal haematoma were managed between July 1999 and December 2002 and the case files were studied retrospectively.

Impact on active scope deflection and irrigation flow of all endoscopic working tools during flexible ureteroscopy.

Objective: Flexible ureteroscopy is nowadays an alternative effective option for treatment of upper urinary tract stones, especially in the lower renal pole. Access in this case is often limited by active deflection capabilities of the instrument which is always deteriorated by the passage of different tools through the working channel. Insertion of them limits also the irrigation flow and so that the visibility.

[Pseudo-tumor form of bladder scleroderma: unusual cause of hematuria].

The bladder is a rare site of scleroderma. The frequency of bladder involvement is difficult to estimate, as only about thirty cases have been reported in the literature. Scleroderma bladder involvement usually presents in the form of frequency and burning, but may sometimes cause urgency or recurrent urinary tract infections.
