A 37-year old woman with locally advanced uterine cervical cancer post concurrent chemoradiation, presented
with an early anastomotic stricture after ileal ureter replacement due to the ischemic process during the reconstruction
procedure. A bilateral ureteral stent was considered in order to relieve the obstructive uropathy. Multiple attempts were
made to cannulate the stricture point between the right renal pelvis and ileal ureter, although all of them failed. The
percutaneous contralateral nephrostomy tract was accessed and successfully used to perform retrograde approach
cannulation. Balloon dilation at the stricture point and ureteral stent placement were successfully performed without any
complications. Therefore, the contralateral retrograde approach for ureteral stent placement during bilateral ileal ureter
reconstruction has been demonstrated to be both feasible and safe.
