Ureteral Catheter Tip Separation: Potential Risk Using the Open-end Flexi-tip Ureteral Catheter

Abstract
Ureteral catheters are a vital part of the urological armamentarium. We report 2 cases in which the flexible tip portion of an open-end Flexi-Tip ureteral catheter became disjointed from the shaft within the renal collecting system during endourological procedures. The etiology, prevention and management of this complication are discussed.
