Objective: After radical prostatectomy, prostate-specific antigen(PSA) value measuring ≥0.1 ng/mL is defined as persistent PSA(pPSA) and in many studies, it was found to be associated with aggressive disease and poor prognosis. Our aim in this study is to point out the pathological and clinical factors affecting pPSA among the patients who underwent robot-assisted radical prostatectomy(RARP) in an experienced academic centre and to make a useful risk grouping algorithm that can predict pPSA value based on operative data.

Introduction: Leiomyomas of the genitourinary tract are rare and their manifestation in the ureter is even rarer. To our knowledge, only 14 cases of leiomyoma of the ureter have been reported worldwide since 1955, therefore this case will be 15th.

Case Presentation: We present a rare case of primary leiomyoma of the right ureter.

Introduction: The success of the robot assisted radical prostatectomy (RARP) procedures depend on a successful team, however the literature focuses on the performance of a console surgeon. The aim of this study was to evaluate surgical outcomes of the surgeons during the learning curve in relation to the bedside assistant's experience level during RARP.

Materials And Methods: We retrospectively reviewed two non - laparoscopic, beginner robotic surgeon's cases, and we divided the patients into two groups.

The elderly population is increasing in Turkey and across the world. With the frequent use of imaging modalities, the detection rate of coincidental small renal mass has also increased. Since small renal masses are generally not malignant, most of them can be followed up by active surveillance.

The aim of this study was to investigate the protective effects of trimetazidine (TMZ), as an antioxidant agent, on streptozotocin (STZ)-induced diabetic rats. A total of 50 male Sprague Dawley rats were randomly classified into five groups as follows: Group 1 (control), Group 2 (STZ-induced diabetic rats), Group 3 (STZ-induced diabetic rats treated orally with 1 cc/day isotonic saline), Group 4 (diabetic rats treated orally with 10 mg/kg/day TMZ) and Group 5 (diabetic rats treated orally with 20 mg/kg/day TMZ). After 8 weeks, orchiectomy was carried out.

Background/aim: The aim of this study was to gauge whether removal of a specimen with traction during robot-assisted laparoscopic radical prostatectomy causes a positive surgical margin or not.

Materials And Methods: One hundred and sixty-nine patients with localized prostate cancer who underwent robot-assisted laparoscopic radical prostatectomy from 2009 to 2011 were included in the study. After dividing the patients into two groups, we recorded their characteristics and pre-op/post-op evaluations.

Objective: In this study we aimed to compare renal functions in patients who underwent robotic partial nephrectomy (RPN) with on-clamp and zero- ischemia techniques.

Material And Methods: Between 2009 and 2015, 12 off-clamp and 22 on-clamp RPN procedures were performed on a total of 34 patients in two centers. The main outcome parameters examined were serum creatinine, and estimated glomerular filtration rate (eGFR) during preoperative, immediate postoperative periods, and at postoperative 3 months.

Purpose: To examine the effect of steep Trendelenburg position (ST) on intraocular pressure (IOP), resistive index of the central retinal artery, and venous impedance index of the central retinal vein during robotic prostatectomy and cystectomy.

Methods: A total of fifty-three male patients were included into the study (prostatectomy: 43, cystectomy: 10). During robotic surgery, the effect of the ST on IOP, resistive index of the central retinal artery (CRA-RI), and venous impedance index of the central retinal vein (CRV-VI) was prospectively examined.

Objective: In this report, we determined the efficacy and the toxicity of low dose weekly gemcitabine with radiotherapy, in medically unfit or refused surgery muscle-invasive bladder cancer (BC) patients.

Materials And Methods: From 2008 to 2012, 15 patients were included into the retrospective analysis. Weekly gemcitabine was administered at a rate of 50 mg/m(2) with a median dose of 63 Gy radiotherapy.

Objective: We evaluated outcomes of our robot-assisted laparoscopic transperitoneal pyeloplasty (RALP) procedures.

Material And Methods: Between July 2011 and March 2014, 18 RALP procedures were performed at our instutition. Ureteropelvic junction obstruction (UPJO) diagnosis was made based on clinical presentation and intravenous urography.

Background: Urinary cytology has low sensitivity and specificity in urinary neoplasm.

Aim: We planned to assess whether the examination of bladder washing before biopsy (WBB) plays a role in better cytologic diagnosis of bladder wash fluid collected after biopsy procedure (WAB) in papillary urothelial neoplasms.

Materials And Methods: We included 36 patients with papillary lesion of bladder.

Background And Objectives: To compare open versus totally intracorporeal robotic-assisted radical cystectomy, bilateral extended pelvic lymph node dissection, and Studer urinary diversion in bladder cancer patients.

Methods: A retrospective comparison of open (n = 42) versus totally intracorporeal (n = 32) robotic-assisted radical cystectomy, bilateral extended pelvic lymph node dissection, and Studer urinary diversion was performed concerning patient demographic data, operative and postoperative parameters, pathologic parameters, complications, and functional outcomes.

Results: Patient demographic data and the percentages of patients with pT2 disease or lower and pT3-pT4 disease were similar between groups (P > .

Introduction: We investigated the reliability and mapping of percutaneous needle core biopsies in the kidney in histopathological diagnosis of renal masses particularly for those with suspicious radiologic appearance in an attempt to prevent unnecessary nephrectomies.

Material And Methods: Overall, 96 cases were included in our study that underwent radical nephrectomy or partial nephrectomy due to renal mass between November 2007 - March 2010. Ex-vivo biopsies 1 cm apart were obtained from the peripheral region of the mass.

Aim: We compared the weight of the prostate specimen extracted after radical prostatectomy with preoperatively estimated weights of the prostate by different imaging techniques.

Materials And Methods: Prostate weights were estimated by transabdominal ultrasonography (TAUS), transrectal ultrasonography (TRUS), and computed tomography (CT) preoperatively before radical prostatectomy. Prostatectomy specimens were weighed postoperatively and the actual prostate weights were calculated.
