[DOES CHOOSING BETWEEN DUSTING OR FRAGMENTATION DURING LASER LITHOTRIPSY OF URINARY STONES CHANGE THE LONG TERM RESULTS?].

Introduction: Variations in laser pulse energy and it's frequency during lithotripsy, affect the rate and the method of stone breaking. The main modes of lithotripsy are dusting and fragmentation.

Aims: Comparison between long term results of dusting versus fragmentation, by defining the stone free rate (SFR) for each method and the time period until re-treatment need.

Comparison of Partial and Radical Laparascopic Nephrectomy: Perioperative and Oncologic Outcomes for Clinical T2 Renal Cell Carcinoma.

Introduction: Nephron-sparing surgery has emerged as the treatment of choice for small renal masses. However, its role in larger tumors remains controversial. In this study, we compare the outcomes of laparoscopic partial nephrectomy (LPN) vs those of laparoscopic radical nephrectomy (LRN) for T2 renal tumors.

Retrospective Analysis of Laparoscopic Partial Nephrectomies Using the Zero Ischemia Technique.

Purpose: To report a series of 89 off-clamp laparoscopic partial nephrectomies (LPN) performed without using any additional "nephron sparing" manipulations.

Methods: Retrospective analysis of surgical characteristics, complications, postoperative results, and renal function changes.

Results: Between March 2008 and May 2014, 89 LPN using zero ischemia technique were performed.

Does the use of ureteral stents with extraction strings increase urinary infection rates?

Purpose: To assess the effect of ureteral stents with extraction string on the rate of postoperative UTI after ureteroscopies.

Methods: Retrospective analysis of patient records who underwent ureteroscopy from January 2011 to August 2014 was performed. Patients were grouped into three groups according to postoperative stent status: non-stented or ureteral catheter for up to 24 h (NS), ureteral stent without extraction string (US) and ureteral stent with an extraction string (US-E).
