Cancerous involvement of a ureter is sometimes encountered in pelvic surgery for malignancy. In these cases, resection and reconstruction of a ureter is indicated. We usually employ transureteroureterostomy (TUU) for reconstruction of a ureter in the cases of unilateral lower ureteral involvement. We report here the outcomes of patients treated with TUU in our hospital. We retrospectively reviewed the medical records of 10 patients who underwent TUU from June 2006 to May 2014. Primary disease was colon cancer in four patients, rectal cancer in four patients, uterine cervical cancer and ovarian cancer in each one patient. Early postoperative complication occurred in only one patient who developed ureteral obstruction and hydronephrosis due to anastomotic hematoma. Follow up periods ranged from 1 to 61 months with a median of 16.5 months. During the follow up periods, no patients experienced either worsening of the renal function or recurrent urinary tract infection. TUU which is a useful and safe ureteral reconstruction method should be considered as a preferable treatment option in patients who undergo resection of the ureter involved by pelvic malignancy.
