Role of ureteral stenting after uncomplicated ureteroscopy for distal ureteral stones: a randomized, controlled trial.

Purpose: We determined the differences in outcome between ureteral stenting and nonstenting following uncomplicated ureteroscopy for distal ureteral stones.

Materials And Methods: A total of 220 patients treated with successful ureteroscopy for distal ureteral stones were randomized to 2 equal groups according to postoperative placement of a ureteral stent (Cook Ireland, National Technological Park, Ireland), including group 1--without a stent and group 2--with a stent. Outcome measures were flank pain and dysuria at 48 hours and 1 week, early postoperative complications, analgesia need, rehospitalization, return to normal physical activity, stone-free rate, stone recurrence and late postoperative complications.
