Bilateral ureteral endometriosis-an indolent, aggressive, and dangerous condition.

Objective: To describe an unusual bilateral ureteral reimplantation due to endometriosis and to provide a flowchart of conservative decision making.

Design: Video description of a case, demonstrating a step-by-step explanation of the decision planning and description of the surgical steps in a female patient with bilateral ureteral endometriosis who had previously undergone operation for bowel endometriosis, and who presented with extensive disease in the posterior compartment with no symptoms besides bilateral renal function disruption. The study was reviewed and approved by the Hospital Beneficência Portuguesa de São Paulo Institutional Review Board.

Robotic-assisted radical cystectomy: the first multicentric Brazilian experience.

The objective of this study is to report the first multicentric Brazilian series and learning curve of robotic radical cystectomy (RARC) with related intra- and postoperative outcomes. We retrospectively analyzed 37 RARC prospectively collected at four different centers in Brazil, from 2013 to 2019. We analyzed the patient's demographics, pathological tumor, and nodal status, as well as intra- and postoperative outcomes.

Outcomes of endovascular treatment of renal arterial stenosis in transplanted kidneys.

Objective: To evaluate the effectiveness and outcomes of endovascular treatment of TRAS with PTA.

Materials And Methods: We searched our prospectively collected database looking at cases of TRAS between January 2005-December 2011. CCT was the gold-standart for diagnosis of TRAS.

Laparoscopic radical prostatectomy: the learning curve of a low volume surgeon.

Objective: Analyze the learning curve for laparoscopic radical prostatectomy in a low volume program.

Materials And Methods: A single surgeon operated on 165 patients. Patients were consecutively divided in 3 groups of 55 patients (groups A, B, and C).

Caliceal-cutaneous fistula after kidney transplantation.

Urinary fistula is a one of the most common complications after kidney transplantation. Conservative treatment with stent and Foley catheter drainage may be tried, however in some cases more invasive approach is needed. Caliceal fistula is a rare condition and the diagnosis may be missed.

Silent ureteral stones: impact on kidney function--can treatment of silent ureteral stones preserve kidney function?

Objective: To report our experience with silent ureteral stones and expose their true influence on renal function.

Methods: We analyzed 506 patients who had undergone ureterolithotripsy from January 2005 to May 2010. Silent ureteral stones were calculi found in the absence of any specific or subjective ureteral stone-related symptoms.

Learning curve for radical retropubic prostatectomy.

Purpose: The learning curve is a period in which the surgical procedure is performed with difficulty and slowness, leading to a higher risk of complications and reduced effectiveness due the surgeon's inexperience. We sought to analyze the residents' learning curve for open radical prostatectomy (RP) in a training program.

Materials And Methods: We conducted a prospective study from June 2006 to January 2008 in the academic environment of the University of Sao Paulo.

Comparison between two shock wave regimens using frequencies of 60 and 90 impulses per minute for urinary stones.

Purpose: Two different regimens of SWL delivery for treating urinary stones were compared.

Methods: Patients with urinary stones were randomly divided into two groups, one of which received 3000 shocks at a rate of 60 impulses per minute and the other of which received 4000 shocks at 90 impulses per minute. Success was defined as stone-free status or the detection of residual fragments of less than or equal to 3 mm three months after treatment.

Urological complication following aortoiliac graft: case report and review of the literature.

Context: Ureteral stenosis and ureterohydronephrosis may be serious complications of aortoiliac or aortofemoral reconstructive surgery.

Case Report: A 62-year-old female patient presented with a six-month history of left lumbar pain. She was a smoker, and had mild chronic arterial hypertension and Takayasu arteritis.

Are total prostate-specific antigen serum levels in cirrhotic men different from those in normal men?

Objectives: To determine the serum total prostate-specific antigen (tPSA) levels in cirrhotic men and compare them with those in noncirrhotic men.

Methods: We prospectively evaluated 113 cirrhotic patients listed for liver transplantation using the serum tPSA, total testosterone level, and Child-Pugh liver function score according to age and severity of liver disease. The tPSA levels were compared with those of 661 healthy men.
