To analyze of clinical data of patients with ureteral fistula and to explore the efficacy of different treatment methods.

19 cases of ureteral fistula caused by various causes were treated in our department from May 2013 to May 2018. There were 4 males and 15 females with an average age of (51±13). Among the 19 patients, 17 patients underwent ureteroscopy and double-J stenting firstly. If ureteroscopy failed, percutaneous nephrostomy or ureteral reimplantation was performed as appropriate. Because of severe infection and obvious allantois, 2 cases were treated with percutaneous nephrostomy and drainage.

Successful ureteroscopy and double-J stenting was performed in 8 cases, and 5 cases finally were cured. Among 9 cases failed of ureteroscopy, 3 cases underwent ureterocystectomy at the same time. Percutaneous nephrostomy was performed in 6 cases, 3 cases of them underwent ureteral reimplantation half a year later due to the inrecovery of anaphase fistula. 3 patients underwent nephrectomy due to repeated infection.

If the ureteroscopy can restore the ureteral continuity, we can try to indwell the double-J stenting. While the ureteroscopy failed, the ureter repair or ureteral reimplantation should be performed at the same time. Nephrostomy will only prolong the course of the disease and cannot change the final outcome. Infection is the main factor leading to final nephrectomy in patients with ureteral fistula.
