Percutaneous Retrieval of Internal Double-J Ureteral Stents Using a Snare

Abstract

Objective: In this paper, we aim to report our experience in percutaneous ureteral stent retrieval using a loop snare under fluoroscopic guidance and to assess the efficacy and safety of the method. Materials and Methods: Between February 2009 and December 2016, electronic records of the patients who underwent percutaneous ureteral stent retrieval were reviewed. A total of 12 patients (8 males, 4 females; age range, 6 months–75 years; mean age, 39.71+-32.3 [standard deviation] years) were included in the study. A loop snare was used to retrieve the ureteral stent from the calyx, renal pelvis, and upper or distal ureters via the vascular sheath. The stent retrieval was performed for endoscopic failure (n=5), proximal stent migration (n=3), early occlusion of the stent (n=2), and stent fragmentation (n=2). A complete percutaneous removal of the ureteral stent with the snare was considered a technical success. Results: Our technical success rate was 100%. There were no major complications. One patient (8.3%) had minor hematuria that resolved spontaneously. Conclusion: Percutaneous ureteral stent retrieval using a loop snare under fluoroscopic guidance is a safe and effective procedure, especially when the cystoscopic removal has failed and stent-related complications occurred.
