Complete extrarenal migration of a double-J ureteral stent following ureteral stone management: A case report
Abstract
Ureteral stenting is widely used to relieve obstruction, but rare complications such as migration may occur. We report a 60-year-old woman with recurrent nephrolithiasis who presented with pyelonephritis due to a left ureteral stone. After antibiotic therapy and double-J stent placement, she underwent three ESWL sessions. Follow-up CT showed remaining fragments and absence of the upper coil of the stent, suggesting extrarenal migration. Extrarenal displacement was confirmed on the day of ureteroscopy by fluoroscopy. The stent was removed and replaced safely; recovery was uneventful. This case highlights the importance of fluoroscopic control and follow-up imaging to reveal uncommon stent-related complications.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
