Abstract/OtherAbstract:
PURPOSE: Long defects in the mid and upper ureter are not amenable to end-to-end reconstruction. Therefore, we present the long-term results of our technique with reconfigured colon segments. MATERIALS AND METHODS: Between June 1998 and July 2008, 14 patients underwent ureteral replacement at our institution with reconfigured colon. In 4 patients the substitute was anastomosed to the skin as a modified colon conduit. In 10 patients it was interposed with anastomosis to the ureter in 4, to the bladder in 5 and to the afferent loop of an ileal bladder substitute in 1. RESULTS: At a median followup of 52.4 months (range 7 to 136) excellent renal function was confirmed in 10 of 14 patients. Now at a median followup of 95.8 months (range 38 to 136) 6 patients are alive, all without an indwelling stent and with no sign of obstruction of the ureteral replacement. Metabolic disorders, mucus obstruction and stricture or adhesive ileus were absent during followup. In this series death was unrelated to the procedure. In 7 patients 11 specific reinterventions were necessary including 4 cases of prolonged stenting after surgery, 3 which required secondary drainage, 3 cases of urinary tract infection at 4 weeks and 3 and 112 months, and 1 acute bowel obstruction due to peritoneal carcinosis. CONCLUSIONS: Reconfigured colon segments can be used successfully to replace long ureteral defects. The advantages are use in patients with impaired renal function and lack of small intestine, proximity of the colon to the ureter, optimal cross-sectional diameter of the graft and less intraperitoneal surgical trauma than with ileal substitutes.
