PURPOSE: The aim of this study was to assess the safety and efficacy of fluoroscopy-guided retrograde double-J stent exchange. MATERIALS AND METHODS: Between March 2003 and June 2005, 39 retrograde ureteral stent exchange procedures on 19 patients and 24 ureters were performed under fluoroscopic guidance. Seventeen of the patients were female and 2 were male. All procedures were done on an outpatient basis unless the patient was already an inpatient. All exchanges were performed through 10 F introducer sheaths. Once the stent was grasped, the sheath, the snare and/or the wire holding the stent were pulled out as a unit. For retrieving the stents, several different techniques (guide wire lasso and wire snaring) were used in addition to simple snare technique. Two parallel stents were placed for each ureter in 2 patients (3 ureters) after a history of stent occlusion in less than 3 months. RESULTS: Technical success rate was 100%. Procedure time ranged from 16 to 38 minutes (average, 21 min). There were no major complications. All patients had minor hematuria after the procedure which resolved within one day. CONCLUSION: Fluoroscopy-guided retrograde double-J stent exchange is a safe and effective procedure and can easily be performed with equipment and techniques used in daily interventional practice.
