Abstract

|
From January 1992 to January 1993, 45 patients with calculi ranging in size from 5×4mm to 22×17mm undrwent lithotripsy with a new pulsed dye laser (Technomed Pulsolith) under the ureteroscpe.
@ES The results were obtained as follows;
@EN 1. The success rates according to location were 60% 3/5) in upper ureter, 63% (7/11) in mid ureter and 93% (27/29) in lower ureter. The mean success rate was 82% (37/45).
2. The success rates according to stone size were 100% (4/4) in below 5mm, 77% (10/13) in 6 to 10mm and 82% (23/28) in above 10mm.
3. The total number of failure was eight. That occured due to various. The causes of failure were the poor visualization in five cases, the laser resistant calcium oxalate stones in two cases and the upward migration in one case. Six cases of
failure
were resolved in spontaneous passing, and two cases were managed by ureterolithotomy.
4. complications were shoed in 17 cases that was gross hematuria in 12 cases (26.6%) and ureteral perforation in 5 cases (11.1%). However. no surgical intervention was needed in all cases.
We conclude that laser lithotripsy with Technomed Pulsolith was considered to be effective and safe procedure for the treatment of lower ureteral calculi.
