尿管内に迷入したステントをFogartyカテーテルで抜去した1例

Abstract

A 64-year-old woman had undergone right percutaneous nephrolithotomy and transurethral ureteroscopy elsewhere. Stenosis of uretero-pelvic junction had occurred. Against the stenosis a double-J ureteral stent was placed within the right ureter and migration of the stent out of the bladder into the more proximal ureter was found after the stent exchange. The patient was referred to us for endoscopic removal and treatment of stenosis. A 4F Fogarty catheter was inserted into the right ureter endoscopically and manipulated up alongside the double-J stent. After the balloon was inflated with 0.8 ml of diluted contrast medium, the stent was removed into the urinary bladder. We have found our method to be convenient and safe in the removal of migrated ureteral stent.
