Comparison of escalating, constant, and reduction energy output in ESWL for renal stones: multi-arm prospective randomized study.

This study was designed to find out the optimized energy delivery strategy in Shock Wave Lithotripsy (SWL) that yield to the best stone-free rate (SFR). In this clinical trial, 150 consecutive patients were randomized into three groups: (a) Dose escalation, 1500 SW at 18 kV, followed by 1500 SW at 20 kV then 1500 SW at 22 kV. (b) Constant dose, 4500 SW at 20 kV.

Lymphatic preservation using methylene blue dye during laparoscopic varicocelectomy: early results.

Background And Objectives: Hydrocele caused by the division of lymphatic vessels during varicocelectomy is a common complication. Preservation of these lymphatics is the aim of many studies. We evaluated patient outcomes after laparoscopic varicocelectomy that involved intratunical methylene blue dye injection just prior to the procedure.

Slow versus fast shock wave lithotripsy rate for urolithiasis: a prospective randomized study.

Purpose: We determined the effect of shock wave lithotripsy (SWL) rate on treatment outcome in patients with renal and ureteral stones.

Materials And Methods: A total of 156 patients were prospectively randomized to receive SWL using a slow (60 pulses per minute) or fast wave rate (120 pulses per minute). Inclusion criteria were patients with a single radiopaque renal or ureteral stone not exceeding 30 mm in maximum diameter.
