Abstract:
Ureteral stents are commonly externalised retrogradely by cystoscopy and exchanged under imaging guidance. When a ureteral stent has migrated proximally into the ureter, it may be snared by ureteroscopy or antegrade percutaneous access; however, ureteroscopy can be challenging in young infants where there is difficulty visualizing the ureteral orifice or a small-calibre ureter. The presented case describes a radiologic technique for retrieval of a proximally migrated ureteral stent in a young infant using a 0.025-in. hydrophilic wire, 4-Fr angiographic catheter, 8-Fr vascular sheath and cystoscopic forceps, without requiring transrenal antegrade access or surgical ureteral meatotomy.
