OBJECTIVE We performed a prospective randomized study to determine appropriate first line treatment for distal ureteral stones. METHODS Between January 1996 and October 1997, 80 patients with distal ureteral stones (40 smaller than 5 mm. and 40 larger than 5 mm.) were randomized and treated with extracorporeal shock wave lithotripsy or ureteroscopy with a 9.5 or 6.5F semirigid ureteroscope. RESULTS Ureteroscopy was significantly better in terms of operative time, fluoroscopy time and time to achieve a stone-free state. The smaller the stones, the greater the difference between the 2 treatment modalities. CONCLUSIONS For distal ureteral stones we recommend ureteroscopy as first line treatment.

UI	MeSH Term	Description	Entries
D008096	Lithotripsy	The destruction of a calculus of the kidney, ureter, bladder, or gallbladder by physical forces, including crushing with a lithotriptor through a catheter. Focused percutaneous ultrasound and focused hydraulic shock waves may be used without surgery. Lithotripsy does not include the dissolving of stones by acids or litholysis. Lithotripsy by laser is LITHOTRIPSY, LASER.
