Abstract

PURPOSE: This study examined the efficacy of ureteroscopic stone manipulation with comparing the success rates and complications rates.
MATERIALS AND METHODS
The manipulation of calculi can be done under the direct vision of ureteroscope using dormia baskets with increasing safety and efficacy. The results of ureteroscopic removal of stones were reviewed in 636 cases. From January 1992 to October 1997, 636 patients underwent ureteroscopic removal of stones.
RESULTS
There were 236 female and 400 male patients between 16 and 75 years old. The success rates of ureteroscopic removal of stones were related to location of the calculus: 95.8% in lower ureter, 87.7% in mid ureter and 90% in upper ureter(overall success rate was 95%). 35 cases(5.8%) of complication occurred in 604 cases of success: Severe ureteral mucosal injury in 25 patients, gross hematuria(>48hours) in 4 patients, ureteral mucosal prolapse in 3 patients, flank pain(>48hours) in 2 patients, ureteral perforation in 1 patient.
CONCLUSIONS
Ureteroscopic removal of stones can be successful and safe treatment modality for lower urethral stones, especially with plentiful experience and good surgical skill.
