PURPOSE: To report the incidence of urinary tract procedures performed during complete cytoreductive surgery (CCRS) plus intraperitoneal chemotherapy, and to report the types of procedure, specific morbidity, risk factors, and treatment. METHODS: Data were extracted from a prospective database of patients with malignant peritoneal disease treated with CCRS plus intraperitoneal chemotherapy who had undergone a resection or suture of the bladder, ureter, or kidney. Patients were eligible whatever the tumor origin. RESULTS: Between 1994 and 2010, among the 598 patients treated with CCRS plus intraperitoneal chemotherapy, 48 (8%) had undergone a resection or suture in the urinary tract. Procedures included 4 nephrectomies, 19 partial cystectomies, 8 surgically repaired bladder injuries, and 18 ureteral resections. Postoperative mortality was 4% and morbidity was 41%. Specific complications included 6 urinary fistulas (12%), two among the 27 bladder sutures (7%) and four among the 18 ureteral sutures (22%) (P = NS). In the multivariate analysis, the risk factors for urinary fistula were severe preoperative malnutrition (P = 0.05, relative risk [RR] = 7.3) and extensive peritoneal disease (peritoneal cancer index ≥20, P = 0.05, RR = 8.3). Urinary fistulas had been treated nonsurgically in most of the cases. CONCLUSIONS: Associated urinary tract procedures had occurred in 8% of the cases but did not greatly increase morbidity. Therefore, urinary tract involvement or injury are not contraindications to performing CCRS plus intraperitoneal chemotherapy. Fistulas had complicated only 12% of urinary sutures, mainly in cases of malnutrition or extensive peritoneal disease.
