Modified N-shaped ileal neobladder after radical cystectomy.

Objective: We report on the feasibility and outcomes of the N-shaped pouch with an afferent tubular isoperistaltic segment as a new technique for creating a capacious, low pressure bladder substitute following radical cystectomy.

Methods: Between April 2000 and April 2006, 42 patients (36 male, 6 female) with invasive bladder cancer were considered good candidates for orthotopic urinary diversion. All had radical cystectomy with bilateral pelvic lymphadenectomy and orthotopic bladder substitution by an ileal low pressure reservoir (N-shaped) with an afferent isoperistaltic tubular segment.

Evaluation of ureteral stent placement after retroperitoneal laparoscopic ureterolithotomy for upper ureteral stone: randomized controlled study.

Purpose: To determine the necessity of ureteral stent placement after retroperitoneal laparoscopic ureterolithotomy (RLU) for upper ureteral stones more than 1 cm.

Patients And Methods: Between May 2006 and May 2009, 104 RLUs were performed as primary management of large upper ureteral stones. The patients were randomly divided into two groups: In group 1 (52 patients), RLU was performed without stent placement afterward, and in group 2 (52 patients), the stent was placed after RLU.

Solo ultrasonography-guided percutanous nephrolithotomy for single stone pelvis.

Purpose: To evaluate the success and outcomes of solo ultrasonography (US)-guided percutaneous nephrolithotomy (PCNL) for management of a single stone pelvis.

Patients And Methods: From April 2008 to April 2010, the procedure was applied to 34 patients (22 men and 12 women) whose ages ranged from 25 to 55 years (mean 29.5 y) with unilateral single stone pelvis in a moderately to markedly dilated pelvicaliceal system (PCS).
