Short-term morbidity and mortality of Indiana pouch, ileal conduit, and neobladder urinary diversion following radical cystectomy

PurposeLiterature surrounding Indiana pouch (IP) urinary diversion suggests a higher incidence of complications and longer operative time compared with ileal conduit (IC) and neobladder (NB). We sought to assess short-term complications of IP diversions compared with other diversions at our institution.Materials and methodsUsing institutional National Surgical Quality Improvement Program data, we identified radical cystectomy cases performed for bladder cancer at Indiana University from January 2011 until June 2013. During this time period, the National Surgical Quality Improvement Program randomly evaluated approximately 70% of radical cystectomies performed for urothelial carcinoma at our institution. Multivariable logistic regression was performed to identify factors associated with Clavien grade III-V complications.ResultsA total of 233 cases were identified, 139 IC, 39 IP, and 55 NB. Mean (standard deviation) operative times for IC, IP, and NB were 257 (84), 383 (78), and 327 (88) minutes, respectively (P<0.001). Half of the patients required blood transfusion during the hospitalization. The overall rate of complications was significantly lower among NB (P = 0.009). Overall, 12% of patients developed a Clavien grade III-V complication, with no difference observed between groups (P = 0.884). After controlling for preoperative confounders, IP patients were not at increased odds of developing a Clavien III-V complication compared with IC (odds ratio = 1.38, P = 0.599).ConclusionsAt a high-volume center, the incidence of serious complications was similar between diversion types. IP patients were more likely to experience minor complications. Patients should be counseled regarding rates of short-term complications and blood transfusion.
