Poster Abstract

Antegrade placement of ureteral stents is common after nephrostomy tube placement for obstruction in the septic patient and when retrograde placement fails. Ureteral stents have a nylon retaining suture attached to aid in placement. If left in place accidentally, these will not degrade and will become embedded in the renal parenchyma preventing stent removal and potentially leading to infection and stone formation. Ureteroscopic holmium ablation of the residual suture at the level of the parenchyma allows for stent removal and no urothelial defect was noted on repeat ureteroscopy 3 weeks later. Ureteroscopy with holmium lasering of retained suture appears safe for removal of retained stents with no symptoms related to suture left in the renal parenchyma and no visible defect seen on follow-up renoscopy.

Case Report: Holmium Laser Removal of Antegrade Ureteral Stent Suture via Ureteroscopy

Antegrade placement of ureteral stents is common after nephrostomy tube placement for obstruction in the septic patient and when retrograde placement fails. Ureteral stents have a nylon retaining suture attached to aid in placement. If left in place accidentally, these will not degrade and will become embedded in the renal parenchyma preventing stent removal and potentially leading to infection and stone formation. Ureteroscopic holmium ablation of the residual suture at the level of the parenchyma allows for stent removal and no urothelial defect was noted on repeat ureteroscopy 3 weeks later. Ureteroscopy with holmium lasering of retained suture appears safe for removal of retained stents with no symptoms related to suture left in the renal parenchyma and no visible defect seen on follow-up renoscopy.
