Transverse colon urinary diversion in gynecologic oncology

Objective: To describe and analyze the outcome of urinary conduits utilizing the transverse colon over an 11-year period. Materials and Methods: All patients undergoing a urinary conduit on the gynecologic oncology service from 1983 to 1993 were identified and a retrospective review was conducted. Results: Transverse colon urinary conduits (TCC) were performed in 86 patients. The majority of patients had a history of cervical cancer (81%), and all but one patient had prior pelvic radiotherapy. TCC was performed in conjunction with pelvic exenteration in 47 patients (55%) and alone as palliation for the effects of progressive malignancy in 10 patients (12%). Other indications for conduit construction included urinary fistulas (19%), ureteral or urethral obstruction (7%), conduit revision (5%), overflow incontinence (2%), or intraoperative ureteral injury (1%). Abnormal preoperative renal morphology was common (48%). A total of 165 ureterocolic anastomoses were performed. Ureteral stents and intestinal staplers were used routinely. The perioperative mortality rate was 3%. Loss of renal function occurred in 10 of 165 renal units (6%). Nineteen (22%) patients had partial ureteral obstruction managed by percutaneous nephrostomy or indwelling stents. Conduit reconstruction was undertaken in 7 patients (8%). Renal calculi were noted in 3 patients. Overall median survival was 30 months. Conclusion: The complications of TCC are similar to those experienced in other urinary diversions. No distinct advantage to using the transverse colon was observed. Management of progressive ureteral obstruction by conservative methods, such as percutaneous nephrostomy or ureteral stents, was frequent and provided a reasonable alternative to reoperation in the poor operative candidate.
