Abstract:
Objective To discuss interventional treatment technique for benign ureteral strictures. Methods A total of 19 cases with 20 benign ureteral strictures were treated with balloon dilatation and double-pigtail ureteral stent placement. Results Among 19 caces,16 were succeeded in a rate of 84.2%.The three failure cases included one of compression by aberrant vessels,one by compression of fibrous-strings and the last one due to tortuosity of the ureter.Re-examinations,by intravenous urography and B ultrasound were carried out in 16 successors,showed gradually release of hydro-nephrosis and renal function improvement.Iatrogenic foreign body ocurred in 2 cases,caused by the protruding tail of stent which had been taken out under ureteroscopy. Conclusions Interventional technique for benign ureteral strictures possesses adventages with mild injury,simple operation,and a new effective method.
