Separated pyelocolocutaneous diversion after bilateral ureterectomy and radical cystectomy for transitional cell carcinoma.

Author information

  • 1Department of Urology, Sentara Cancer Institute, Norfolk, Virginia, USA.



To report a technique for excision of bilateral ureteral transitional cell carcinoma which preserves renal function and provides ready access for endoscopic follow-up and therapy of the renal pelvis.


The operative procedure of bilateral ureterectomy with construction of a separated pyelocolocutaneous diversion utilizing transverse colon is described and the clinical course of 4 patients is reported.


All 4 patients maintained excellent renal function and normal electrolytes. Conduit urine cytologic studies and renal pelvis endoscopic examinations have remained normal. Parastomal herniation was the most frequently observed postoperative complication.


This approach is well suited for the treatment of bilateral ureteral transitional cell carcinoma. Long-term complications are minimal and renal function is preserved. Periodic endoscopic visualization of each renal pelvis with resection and fulguration and/or instillation of immunotherapeutic or chemotherapeutic agents for recurrent renal pelvic lesions is readily accomplished.
