Transurethral retrieval of a proximally dislodged ureteral stent.

A proximally migrated ureteral stent into the renal pelvis is an uncommon problem that poses a difficult technical challenge. A 32-year-old woman had her ureteral stent inadvertently dislodged into the renal pelvis at the time of stent exchange. The stent was successfully retrieved and repositioned transurethrally with a snare fed through the left ureter and into the renal pelvis. This is a relatively noninvasive method of retrograde retrieval of a proximally dislodged ureteral stent.
