Abstract
|
|
|
We performed 113 ureteroscopies for stone removal in 110 patients between August 1989 and March 1992. The stones were removed successfully in 107 cases (94.7%) and complications occured in 16 cases (14.2%). In 6 cases, we failed to failed to
remove
ureteral stones due to inability to introduce ureteroscope at UVJ (one case), severe angulation of ureter (2 cases) inadequate illumination due to bleeding (one case) and upward migration of stones (2 cases). Complications consisted of tearing of
ureteral mucosa (5 cases), ureteral perforation (5 cases), fever (2 cases) gross hematuria (2 cases) and infection (2 cases). There was no evidence of ureteral stricture on excretory urograms of 52 patients taken at 3 months postoperatively.
Complication rate decreased according to accumulation of experience and it had no correlation with stone size or location. All complications were treated successfully with conservative measures. We conclude that ureteroscopic stone removal is a
safe and
effective method fortreatment of mid-and lower ureteral stones.
