The impact of retrograde intrarenal surgery for asymptomatic renal stones in patients undergoing ureteroscopy for a symptomatic ureteral stone.

Background And Purpose: In the era of rigid ureteroscopy (URS) for ureteral stones, asymptomatic renal stones were often left in place. With the advent of flexible URS, however, the treatment of such renal stones became an attractive option. Data are scarce regarding the impact of retrograde intrarenal surgery (RIRS) performed at the time of URS for a symptomatic ureteral stone in comparison with ureteral stone removal alone.

Transurethral resection of bladder tumour complicated by perforation requiring open surgical repair - clinical characteristics and oncological outcomes.

Objective: • To examine the clinical characteristics and long-term outcomes of patients with bladder perforation requiring open surgical repair as a complication of transurethral resection of bladder tumour (TURBT).

Patient And Methods: • A search of our institutional database yielded 4144 patients who underwent TURBT from 1996 to 2008, of whom 15 (0.36%) required open surgical intervention to repair a large bladder perforation.

Predictors of nocturia quality of life before and shortly after prostatectomy.

Objectives: To evaluate the predictors of nocturia-related quality of life and to assess the early effect of prostatectomy on these parameters in patients with lower urinary tract symptoms suggestive of benign prostatic obstruction.

Methods: The study group included 56 consecutive patients scheduled for prostatectomy to treat medical treatment-refractory lower urinary tract symptoms. Nocturia severity was assessed preoperatively and 2 to 3 months after prostatectomy by the number of nocturia events, time from falling sleep to first awakening to void (hours of undisturbed sleep [HUS]), longest sleep interval between voids, and score on the nocturia quality-of-life (N-QOL) questionnaire (range 0 to 48).

Early initiation of aspirin after prostate and transurethral bladder surgeries is not associated with increased incidence of postoperative bleeding: a prospective, randomized trial.

Purpose: Lower urinary tract operations are being increasingly performed in elderly patients, in whom aspirin intake is common for preventing cardiovascular disease. We determined the safety of early aspirin re-initiation after lower urinary tract surgeries.

Materials And Methods: A randomized, open label clinical trial was done.

Expanding use of ureteral access sheath for stones larger than access sheath's internal diameter.

The internal diameter of the ureteral access sheath limits the size of stones that can be removed during flexible ureteroscopy. We describe a technique that allows removal of larger stones, which are entrapped and removed en bloc with the access sheath. This new technique was shown to be efficient and safe.
