[A case demonstrating knot formation at the upper end of a ureteral stent].
A 37-year old man underwent extracorporeal shock wave lithotripsy for left renal stones after placing a ureteral stent (6 Fr multilength stent). Three months later the stent could not be extracted because of knot formation at the upper end. We performed ureterotomy and removed the stent.
