Objective: To assess results of the treatment of ureteral lesion with minimally invasive strategy. Material and methods: From 1991 to 2004, we treated 12 patients with iatrogenic ureteral injuries. Eleven patients were diagnosed after gyneacologic operation and one after appendectomy. The injuries were detected 5–45 days (average 13.1 days) after initial procedure. Results: Nine patients were treated by stent placement, 5 had spontaneous recovery of injured ureters during 24–177 days (average 117 days). Dilatation of the ureteral stricture were needed in 2 patients. The time of stent placement was 191 and 277 days, respectively. Open repair were needed in 2 patients after 90 and 99 days, because of ureteral stricture and ureterovaginal fistula. Percutaneous nephrostomy with ureteral stent placement was performed in 3 patients, all lesions were completely recovered in 98 days (range 42–175 days). Conclusion: Treatment of the late recognized iatrogenic ureteral lesion with stent placement, percutaneous nephrostomy drainage or both, are one of the possible options and represents safe and minimally invasive strategy.
