Extra-anatomical complications of antegrade double-J insertion.

Introduction: Insertion of a double-J (JJ) stent is a common procedure often carried out in the retrograde route by the urologists and the antegrade route by the radiologists. Reported complications include stent migration, encrustation, and fracture. Extra-anatomic placement of an antegrade JJ stent is a rare but infrequently recognized complication.

A unique extra-anatomic urinary diversion!

The ureter is often involved in pelvic malignancy, leading to obstruction, hydronephrosis, and deterioration of renal function. Decompression is provided either by retrograde stenting or by nephrostomy followed by antegrade stent insertion. We present an interesting case where an iatrogenic accident during antegrade stenting led to the placement of the lower end of the stent in the rectal stump.
