“…Retrograde ureteroscopy and holmium laser fragmentation of the knot has also been reported to have effective outcomes. 22 , 24 , 26 However, passing the ureteroscope through the side of the retained stent is technically challenging. More invasive procedures, such as the percutaneous approach and open ureterotomy, have also been described.…”

Purpose: Encrusted and knotted stents may cause serious urologic complications. This study aimed to develop a novel and minimally invasive technique to manage encrusted or knotted retained ureteral stents. Materials and Methods: This technique was used in nine patients with retained stents. Through rigid cystoscopy, the stents were pulled out of the urinary meatus. The access sheath was modified by cutting the distal end of its obturator. The modified access sheath was advanced over the retained stents in a telescopic manner to remove the encrusted and/or knotted stents. Results: Six patients had encrustations, two had knot formation, and one had both encrustation and knot formation. The encrustations were peeled off in the process. The knots were either undone or pulled through the lumen of the access sheath. The retained stents were removed intact from all patients without any complications. Conclusion: The access sheath method described in this article provides a simple alternative for the removal of encrusted or knotted retained stents. However, this technique requires further validation to establish its safety and efficacy.

“… 1 Since then, advances in surgical techniques and stent materials have led to an increase in the indications for its use. Although ureteral stent use can cause various complications, 2 stent knotting in the renal pelvic or ureter is a rare complication, which makes the extraction of the knotted stent very challenging. Herein, we present a case of a single‐J ureteral stent knotting in a patient treated with ureterocutaneostomy.…”

Knotted ureteral single‐J stent in a patient with ureterocutaneostomy

Introduction Although ureteral stent catheterization is a common procedure in urological practice, knotting of a ureteral catheter is a very rare complication. Case presentation A 62‐year‐old man underwent cystectomy and ureterocutaneostomy for bladder cancer. The ureteral single‐J stent was changed every month postoperatively without complications. However, at postoperative 30 months, resistance was experienced while adjusting the stent position after the exchange. Abdominal radiography revealed knotting of the stent at the right renal pelvis. The knotted stent was percutaneously removed because the patient had only one functioning kidney. A nephrostomy tract was established and the ureteral stent was exchanged. No complications occurred in the perioperative period. Conclusion We encountered a case of a knotted ureteral single‐J stent in a man treated with ureterocutaneostomy. In this case, resistance was noticed during extraction; the possibility of stent knotting should always be considered, and an appropriate removal strategy must be planned.

Novel application of an established technique for removing a knotted ureteric stent

Abstract: This report describes a case whereby a ureteric stent became knotted during removal and lodged within the upper ureter. The authors describe a novel minimally invasive technique to remove the knotted ureteric stent using the holmium laser.
