The ureteroileal anastomotic
stricture is a complication of
ileal conduit urinary diversion. To prevent the
hydronephrosis and protect the renal function, a single-J ureteral
stent may be needed. However, the most common complication of these patients is single-J
stent obstruction. To solve this problem, we describe an easy, useful and low-cost technique to replace the obstructed ureteral
stent under radiographic guidance without intervention by flexible cystoscopy or percutaneous nephrostomy. The key steps of our procedure are to identify the location of the
stricture, to place the super smooth guide wire into pinhole of the obstructed single-J
stent and to get the super smooth guide wire and 5-Fr
ureteral catheter across the
stricture. Our case was a 40-year-old male patient who was diagnosed as
pelvic lipomatosis and received
ileal conduit urinary diversion 3 years ago. The left-side ureteroileal anastomotic
stricture occurred 1 year after surgery. He refused to repair the
stricture by open or other minimal invasive surgery. He regularly changed his ureteral
stent with intervals of three months. As the
stent was obstructed by the stone, the guide wire couldn't be inserted through the primary ureteral
stent. We used our "bridge" technique to solve his problem successfully. No
bleeding and no
urinary tract infection were observed after intervention. The urine from the ureteral
stent was fluent. We think that this "bridge" technique may be a good choice for the replacement of the obstructed single-J
stent in the patients of
ileal conduit urinary diversion.
