Ureterocolic fistula secondary to a self-expanding retrievable ureteral stent.

Abstract

Self–expanding stents are relatively new in the field of urology and have primarily been used for permanent remodeling of benign or malignant stricture. We are presenting a rare and interesting case of a ureterocolic fistula that formed secondary to placement of an expandable, retrievable metal stent in the ureter. After multiple retrieval efforts, the self–expanding metal stent was finally retrieved and a ureterocolic fistula was appreciated on antegrade pyelography. The patient chose to manage it non–surgically, with routine nephroureteral catheter exchanges, and her creatinine continues to remain stable.
