Ultrasonographic evaluation of urethral stricture disease.

Twenty-four male patients with known or suspected urethral stricture disease were evaluated using ultrasonic urethrography and standard retrograde x-ray urethrography for comparative analysis of the two techniques. Each patient also had cystoscopy for direct visual verification of the extent of the stricture. Ultrasonic urethrography proved a simple, yet sensitive and reliable, diagnostic study that can provide more accurate information regarding stricture length, lumen caliber, and extent of spongiofibrosis than radiologic urethrography. It allows examination of the urethra in different planes. The ultrasonic equipment is portable, and ultrasonic study provides the distinct advantage of avoiding ionizing radiation.
