Internal ureteric stents are secured to the tip of the urethral catheter with nonabsorbable suture facilitating removal of the stents postoperatively 2-3 weeks along with the urethral catheter. This surgical modification was applied to 21 patients of whom no significant surgical or infectious complication due to single urethral catheter was observed. Internal ureteral stenting is simple, safe and inexpensive alternative to conventional methods to support ureteroileal anastomosis in patients undergoing orthotopic bladder substitution.展开更多
