Emergency ureteroscopic lithotripsy in acute renal colic caused by XXXX : a retrospective study.

@entity1 @entity4 @entity1607
This work was conducted to evaluate the safety and efficacy of emergency ureteroscopic lithotripsy in @entity1 with ureteral stones. From May 2003 to December 2010, 244 @entity1 (184 @entity1 and 60 @entity1 , mean age 45.6    12.7 years (range 22-73 years) were treated with emergency ureteroscopic lithotripsy for @entity1607 . All @entity1 were divided into three groups according to the stone location in the ureter. Intracorporeal lithotripsy when necessary was performed with the Swiss lithoclast. The overall stone-free status was defined as the complete absence of stone fragments at 4 weeks, postoperatively. A double J stent was inserted in selected @entity1 if there was significant ureteral wall trauma, @entity4 at the stone impaction site, suspected or proved ureteral perforation, and if the stone migrated to the kidney. The overall success rate was 90.6%. The success rates were different according to the stone site. The success rate of groups A, B and C was 69.4, 94.8 and 96.6%, respectively. The overall rate of ureteral stent insertion at the end of the procedure was 177/244 (72.5%). The rate of stent insertion was 41/49 (83.7%), 32/46 (69.6%) and 104/149 (69.8%) in groups A, B and C, respectively. The overall complication, failure, and stricture rate was 32/244 (13.1%), 23/244 (9.4%) and 0.8%, respectively. With the recent advances in ureteroscopic technology, intracorporeal probes and stone extraction devices, emergency ureteroscopy is found to be a safe and effective procedure with immediate relief from ureteral colic and ureteral stone fragmentation.
