A penile clamp for retrograde urethrography using external compression by a balloon catheter.
A penile clamp for retrograde urethrography is described. The seal around the fine-bore catheter that injects the contrast is produced by external compression of the penis by the air-filled balloon of a large Foley catheter that acts against counter-pressure from an encircling bandage.
