OBJECTIVE: To investigate the functional outcomes of ileal ureter replacement for complex ureteral loss, including bilateral and single ureter stricture, as a result of various etiologies.
METHODS: In 2013-2016, 31 patients underwent ileal ureter replacement surgery. The data for their assessments included etiology, combined surgical procedures, ureteral replacement type, postoperative complications, and changes in renal function.
RESULTS: The 31 study patients had a median age of 56.0 (range 18-65) years and were followed for a median of 23.6 (range 6.5-43.2) months. There were 14 bilateral, 12 unilateral, and 5 single-kidney cases. The main indication for surgery was ureteral defects after gynecological surgery and radiation in 24 patients (77.4%). The mean operation time was 370.6 minutes and the median hospital stay was 25.2 (range 6-79) days. Various types of ileal arrangement were performed to cover bilateral ureter loss. After 30 days past surgery, 24 patients (77.4%) were in a stable state and 5 (16.1%) had decreased serum levels of creatinine. Short-term complications greater than grade 3 on the Clavien scale occurred in 10 patients (33.3%), and long-term complications occurred in 27 (87.1%). However, all cases were well relieved by conservative care, and surgical intervention was needed in only 1 case. Apart from 2 patients who died because of the progression of cervical cancer, all patients had stent-free status at 22.4 months.
CONCLUSION: Ileal ureter replacement is a useful reconstructive surgery for complex ureteral loss, such as bilateral and single-kidney cases resulting from various etiologies.
