Abstract
Objective:
To report a minimally invasive and reproducible technique that greatly facilitates the identification of the stricture during laparoendoscopic single-site ureteroureterostomy (LESS-UU) for benign proximal and middle ureteral strictures, using the intraoperative retrograde ureteroscopy-assisted technique.
Patients and Methods:
Between April 2011 and January 2013, 13 patients with a benign proximal or middle ureteral stricture underwent LESS-UU at our institution. A combination of diuretic renal scans, antegrade/retrograde ureteropyelography and/or computed tomography, and stent placement or exchange was preoperatively performed to assess all patients. The intraoperative retrograde ureteroscopy-assisted technique was used to identify the exact position of the stricture and place the stenting during LESS-UU.
Results:
Intraoperative retrograde ureteroscopy was successfully performed in all cases. The mean operative time was 156 minutes (range, 125–190 minutes), and the estimated blood loss was 80 mL (range, 20–160 mL). The mean hospital stay was 5 days (range, 4–7 days). One patient required conversion to open surgery because of the severe adhesions surrounding the stricture that resulted in failure to progress. Urine leakage occurred in 1 patient postoperatively and was successfully treated by conservative management. Postoperative fever occurred in another patient, who was treated with a dose of oral antibiotics. No major intraoperative or postoperative complication occurred. Clinical and radiographic success was achieved in 100% (13/13) of patients during a mean follow-up of 13.1 months (range, 9–27 months).
Conclusions:
LESS-UU is feasible and safe for repairing benign proximal and middle ureteral stricture. The intraoperative retrograde ureteroscopy-assisted technique during LESS-UU is useful for localizing the stricture.
