[Ureter perforation in ureterorenoscopy--management and follow-up]

From 1984 to 1988 in 65 patients an ureterorenoscopic operation have been performed because of lower ureteral stones. An ureteral perforation was observed in 6 out of 65 patients (9.2%). In 5 patients an ureteral stent was introduced and one patient had an open operation. In one patient as a late complication an ureteral neoimplantation because of prevesical stenosis was necessary. In ureteral perforation due to ureterorenoscopy an ureteral stenting or a percutaneous nephrostomy should be done.
