Abstract: Objective：To investigate the cause, diagnosis, secondary operation and treatment experiences of iatrogenic lower ureteral injury. Methods：The clinical data of 10 patients with iatrogenic lower ureteral injury were analyzed. Results：Among the 10 cases of iatrogenic lower ureteral injury, 9 cases were from the Department of Obstetrics and Gynecology, 1 case was from the Department of Urology. The secondary repair operations included the combined renal puncture fistula, ureteroneocystostomy, and double J-tube drainage. After 6 to 42 months of follow-up, only 1 patients had mild hydronephrosis, whereas the ureters of all patients were smooth, the urinary leakage disappeared, and the renal function was normal. Conclusions：As long as the general situation of the patients with iatrogenic ureteral injuries is good, repair surgery is feasible. Ureteroneocystostomy is one of the preferred methods for the treatment of iatrogenic lower ureteral injury.
