Introduction:
Laparoscopic ureteroureterostomy (UU) is a preferred and valid minimally invasive procedure for treatment of benign ureteral strictures. In some cases with chronic inflammation or after repeated endoscopic ureteral surgery, it is difficult to identify the location of a ureteral stricture.
Presentation of case:
We report a case of 48-year-old man with an impacted stone after laparoscopic partial nephrectomy. Although transurethral lithotripsy (TUL) was performed, the ureteral stricture did not improve by subsequent endoscopic ureteral Holmium laser incision and balloon dilation.
Discussion:
To simultaneously identify the exact location of the constriction, we performed retroperitoneal laparoscopic ureteroureterostomy with intraoperative observations via super-slim flexible fiberoptic ureteroscopy retrograde.
Conclusions:
Accurate identification of the ureteral stricture via observation by laparoscopy and observation by ureteroscopy was feasible. In contrast to the use of a rigid ureteroscopy, flexible fiberoptic ureteroscopy did not require placing the patient in an unnatural position.
