Currently, the total ureteral avulsion are mainly secondary to ureteroscopy, and it is rarely caused by uterine evacuation clinically. This paper reported a case of total ureter avulsion after uterine evacuation, treating by ileal replacement for ureter under general anesthesia, and the surgical outcome was good. Uterine evacuation is a routine, less risky procedure, but it also can lead to serious complications such as total ureteral avulsion or bladder rupture. For potential high-risk patients with uterine evacuation, preventive measures such as accurate localization under B-ultrasound guidance or pre-operative ureteral stents indwelling are useful to avoid the occurrence of such serious complications. If total ureteral avulsion occurs, ileal replacement for ureter is a viable and effective treatment.
