Retrograde radiological retrieval and replacement of double-J ureteric stents

Abstract

Internal double-J stents are used to maintain ureteral patency and require replacement within 4-6 months. We present our experience with 15 consecutive patients who had 35 internal ureteral stents retrieved and in whom 27 were successfully replaced, retrogradely under fluoroscopic control. The double-J stents were retrieved using an Amplatz gooseneck snare. Replacement was more successful in female patients, and was technically more difficult via an ileal conduit or transplant ureter. We found this new technique to be straightforward and well tolerated by the patients. The procedure was performed on an outpatient basis, and no serious complications were reported. This technique is considerably cheaper than cystoscopic replacement under epidural or general anaesthesia, and is recommended for the retrieval and replacement of internal ureteral plastic stents in most patients.
