[Balloon dilation by B ultrasound monitoring for treatment of urethral stricture: 5 case reports].

Urethral stricture is a common urologic disease and there are many therapeutic methods for it. Here we investigated the application of balloon dilation under B-mold ultrasound monitoring in the treatment of urethral stricture. Five male patients suffering from urethral stricture were treated with balloon dilation under B-mold ultrasound monitoring.Their urination was assessed after operation. All the patients underwent the operation successfully, without serious complications. The urinary catheter was removed 3-4 weeks after operation. The patients were followed up for 8 to 15 months. Four patients were voiding well and one improved. Balloon dilation under B-mold ultrasound monitoring in the treatment of urethral stricture was intuitive, safe and effective.
