Jermini F R - - 2002
PURPOSE: Spontaneous ureteral stone passage often causes severe renal colic, especially when the stone passes through the narrow ureteral orifice. In these situations noninvasive anesthesia-free, analgesia-free and radiation-free extracorporeal shock wave lithotripsy (ESWL) (Dornier Medical Systems, Marietta, Georgia) is a valuable tool. It can be performed at any time without ...
Aynehchi Shahrad - - 2002
BACKGROUND AND PURPOSE: When intervention is necessary, controversy remains as to the best treatment modality for stones of the distal ureter. In general, ureteroscopy is favored over extracorporeal shockwave lithotripsy (SWL) as the treatment of choice for distal ureteral stones. Although uncommon, ureteroscopy failures have traditionally necessitated repeat ureteroscopy to ...
