Ureteral Guidewire Looping and Entrapment above an Impacted Ureter Stone

We present a rare case of a hydrophilic guidewire looping and entrapment in the ureter of a patient with an impacted stone in the proximal ureter during a simple double-J stent insertion. Looping of guidewire is a rare complication in urology and only few cases have been described. In that case, release and removal of the entrapped guidewire was possible only after one step fragmentation of the stone with laser lithotripsy.
