A pure leiomyoma of the prostate, a rare tumor with fewer than 30 documented cases, typically initiates as focal points within the gland, causing prostatomegaly. Pathological examination is crucial for diagnosis, distinguishing it from leiomyosarcoma. Complete tumor resection is preferred, with methods like transurethral resection, open adenomectomy, or prostatectomy.

Aims: To report contemporary outcome of patients with XGP, managed with either open nephrectomy (ON) or LN.
Settings And Design: In this retrospective study, medical records of 37 patients with histopathologically confirmed XGP from January 2001 to October 2009 were reviewed.
Introduction: The purpose of this study was to compare in a randomized fashion the clinical outcomes following standard laparoscopic and laparoendoscopic single-site (LESS) donor nephrectomies.
Materials And Methods: Fifty voluntary renal donors who met the inclusion and exclusion criteria were randomized to standard laparoscopic (group A) and LESS (group B) donor nephrectomies. The primary end point of the study was patients' postoperative pain.
Background: Chikungunya is a viral infection often associated with lower urinary tract dysfunction. This study evaluates the urological squeal of Chikungunya fever in a single centre after an epidemic in 2006-2007 in India.
Materials And Methods: Retrospective analysis of medical records of 13 patients with lower urinary tract symptoms after Chikungunya fever was evaluated and outcome following intervention assessed.
Objective: • To compare the content validity (realism and usefulness) of percutaneous renal access (PRA) obtained on a live porcine model and a high-fidelity computer-based surgical simulator (PERC Mentor, Simbionix; Lod, Israel) in our skills laboratory for trainees interested in PRA training, so as to determine which of the two is a more appropriate and effective training model.
Materials And Methods: • In all, 24 'experts' performed PRA in a live porcine model and using the PERC Mentor. • The porcine model access required a live anaesthetized pig with a pre-placed ureteric catheter.
Introduction: Donor gonadal vein is a readily available vascular reconstruction material for vascular reconstruction, for difficult situations, in living related renal transplantation. Vein extension with the gonadal vein has been described as a simple and safe method to elongate renal vein especially in right living donor kidneys. We applied the donor gonadal vein for lacerated accessory renal artery and renal vein reconstruction.

Methods: The paper is a singlecenter retrospective data review of renal transplant recipients from 1980 to 2007. A total of 1700 patients received kidneys from live donation, and 9 patients received from cadaver donor.
Background: Uro Trainer (UT; Karl Storz GmbH, Tuttlingen, Germany), a virtual reality simulator for transurethral resection of prostate (TURP), has been infrequently validated. To ascertain the utility of such a trainer, we performed a basic face and content validity study.
Materials And Methods: Ten experts and nine novices (done more than 50 and less than 3 TURPs, respectively) performed a TURP on UT and rated simulator usefulness (seven items), realism (five items), and overall score (one item) on a Likert's 10-point scale.
Purpose: The aim of this study was to evaluate the effect of stone attenuation value on the effectiveness of extracorporeal shockwave lithotripsy (SWL) for upper urinary tract stones.
Methods: In this prospective study, 99 patients underwent SWL for solitary renal and upper ureteral stones from January 2007 to March 2009. All patients underwent CT scan before SWL.
End-stage renal disease is a significant health problem. The primary use of the autogenous arteriovenous access is recommended by NKF-DOQI (National Kidney Foundation-Dialysis Outcomes Quality Initiative) guidelines. Though basilic vein transposition is well established in multiple failed fistulae's and obese patients, it requires large incision and morbidities like edema and infection.

Materials And Methods: A cohort of 24 participants comprising novices (n = 15) and experts (n = 9) performed a specific task of percutaneous renal puncture using the same case scenario on PERC Mentor. All objective parameters were stored and analyzed to establish construct validity.
Objective: To establish the efficacy of early removal of a nephrostomy tube after percutaneous nephrolithotomy (PCNL), to challenge the wisdom of tubeless PCNL, as we hypothesized that it would result in a shorter hospital stay, comparable benefit and safety, while maintaining the option of check nephroscopy ensuring far superior stone clearance.
Patients And Methods: In all, 22 patients were prospectively randomized equally into two groups, group 1 (early nephrostomy removal) or group 2 (tubeless) during a 1-month study period. Inclusion criteria for the study were: a simple stone of <3 cm, no significant bleeding, no perforation, single-tract access and 'on-table' complete stone clearance.
Introduction: Laparoscopic adrenalectomy remains a controversial procedure for large tumors. The incidence of adrenocortical carcinoma increases and technical difficulty of adrenalectomy increases as the size increases. We examined the outcome and complications of laparoscopic adrenalectomy for such lesions.
View Article and Find Full Text PDFIntroduction: The impact of percutaneous nephrolithotomy (PCNL) in chronic kidney disease (CKD) patients was retrospectively analyzed in this study. We analyzed the factors that can impair renal function and predict the need for renal replacement therapy (RRT) after PCNL.
Patients And Methods: Ninety-one chronic kidney patients with a mean age of 52.
Objectives: To present our experience with 13 patients undergoing laparoendoscopic single-site live donor nephrectomy.
Methods: The Quadport/Triport (Advanced Surgical Concepts, Ireland) was inserted through an incision in the umbilicus. Apart from standard laparoscopic instruments, we used extra-long harmonic scalpel, suction, and bent instruments, particularly for upper pole dissection.
Purpose: To create a model for laparoscopic pyeloplasty training using the crop and esophagus of a chicken. The model can be used to simulate the steps taken during laparoscopic pyeloplasty and to help trainees practice laparoscopic suturing skills.
Materials And Methods: The chicken crop and esophagus were used to simulate the renal pelvis and ureter, respectively.
Aims: To compare laparoscopic radical nephrectomy (LRN) with open radical nephrectomy (ORN) in T1-T3 renal lesions.
Materials And Methods: The records of 65 patients who underwent LRN between January 2002 and December 2006 were entered prospectively in a database. The patients were compared with 56 patients who had undergone ORN between January 2000 and December 2005.
