[Foreign body in proximal ureter after selective embolisation of a renal artery].

Colic attacks by a foreign body in the urinary tract are very rare and mostly follow iatrogenic manipulation. This case report focuses on ureteric colic thought to result from radiological embolisation material. It is of practical interest because embolisation of prolonged bleeding after endourological procedures is widely done.An 80-year-old woman with a long history of nephrolithiasis underwent percutaneous nephrolithotomy. She suffered from a continuous, transfusion-obligatory bleeding. The source of bleeding was treated with embolisation by coiling. About 2 years later, the patient presented with persistent pain on the right abdominal side and urinary obstruction. A dislocation of the coils into the ureteropelvic junction was diagnosed. After primary ureteral stenting, the foreign body was removed via ureterotomy.
