Optimization of Extracorporeal Shock Wave Lithotripsy Delivery Rates Achieves Excellent Outcomes for Ureteral Stones: Results of a Prospective Randomized Trial.

Purpose: Management of ureteral stones remains controversial. To determine whether optimizing the extracorporeal shock wave lithotripsy delivery rate would improve the treatment of solitary ureteral stones we compared the outcomes of 2 delivery rates in a prospective randomized trial.

Materials And Methods: From July 2010 to October 2012, 254 consecutive patients were randomized to extracorporeal shock wave lithotripsy at a shock wave delivery rate of 60 and 90 pulses per minute in 130 and 124, respectively.
