A new device for retrograde urethrography in the male.

A new technique is presented for retrograde urethrography (RGU) using a plastic adjustable clamp. The procedure was performed in 36 patients with suspected urethral stenosis. Mean age was 55.3 years. The device and the procedure are described. All the radiologic examinations of the urethra were carried out successfully. The urethrograms showed images of stenosis in 27 patients. The stenoses localized in the distal tip of the anterior urethra were clearly seen with this clamp system. This method enables evaluation of the cases with stenosis close to the meatus that are difficult or even impossible to visualize with the conventional method. When necessary, a finer catheter can be used. This clamp system is recommended for RGU. The technique is simple, effective, and well tolerated by patients.
