[Therapeutic and diagnostic ureterorenoscopy. Analysis of the procedure and results].

The present study reports our experience with URS. With this procedure, we have achieved results similar to those reported in the literature. Of a total of 97 URS procedures, 12 cases (17.5%) presented minor complications which resolved with conservative treatment. One patient presented ureteral perforation, a major complication that warranted open surgery. No renal unit was lost. The procedure permitted accurate diagnosis in all of the cases with a doubtful ureteric pathology. The foregoing demonstrates its high sensitivity and specificity.
