The use of ureteral stents has become one of the most common utilized tools in the era of endourology armamentarium. The indications for their placement have expanded significantly; however, their use is not free of complications and consequences. Stent knotting is uncommon complication when using multilength coiled stents; hereby we present a case of using ureteroscopy and Holmium laser to manage a knotted stent proximal to a mid-ureteric stone. After we reviewed literature, we found that knotting of multilength ureteral stents represents a rare complication that might be a significant challenge to the endourologists. Selection of the correct length of stent and assuring good position with x-ray guidance during insertion and removal might help avoiding this complication.

Key words: Ureter, knotted ureteral stent, stones, urological complications.
