Purpose We evaluated long-term surgical complications and clinical outcomes in a large group of patients treated with conduit urinary diversion. Materials and Methods We identified 1,057 patients who underwent radical cystectomy with conduit urinary diversion using ileum or colon at our institution from 1980 to 1998 with complete followup information. Patients were followed for long-term clinical outcomes and analyzed for the incidence of diversion specific complications. Results A total of 844 patients died at a median of 4.1 years (range 0.1 to 28.1) following cystectomy. Median followup of the surviving 213 patients was 15.5 years (range 0.3 to 29.1). There were 643 (60.8%) patients with 1,453 complications directly attributable to the urinary diversion performed with a mean of 2.3 complications per patient. Bowel complications were the most common, occurring in 215 patients (20.3%), followed by renal complications in 213 (20.2%), infectious complications in 174 (16.5%), stomal complications in 163 (15.4%) and urolithiasis in 162 (15.3%). The least common were metabolic abnormalities, which occurred in 135 patients (12.8%), and structural complications, which occurred in 122 (11.5%). Increasing age at cystectomy (HR 1.21, p <0.001), increasing Eastern Cooperative Oncology Group performance status (HR 1.23, p = 0.02) and recent era of surgery (HR 1.68, p <0.001) were significantly associated with a higher incidence of complications. Conclusions Conduit urinary diversion is associated with a high overall complication rate but a low reoperation rate. Long-term followup of these patients is necessary to closely monitor for potential complications from the urinary diversion that can occur decades later.
