title: Sonographic urethrogram: comparison to roentgenographic techniques in 22 patients.
abstract: A sonographic technique was devised to examine the anterior urethra in 22 men suspected of having stricture disease. All patients underwent sonographic and roentgenographic urethrograms. Cystoscopic examination was done in 17 patients. The sonographic urethrogram findings were as diagnostic as the roentgen findings in 19 patients. In 1 patient the sonographic urethrogram identified a bulbar urethral stricture not seen on a retrograde urethrogram. In 2 patients a bulbar urethral sinus tract was found by the retrograde urethrogram but not by the sonographic urethrogram, although the remaining 2 sonographic urethrograms correctly identified the urethral pathological condition. Structures outside the lumen of the urethra including the urethral wall, corpus spongiosum, corpus cavernosum, bulb and external urinary sphincter were seen clearly by the sonographic urethrogram. The fossa navicularis can be visualized as well. Foreign bodies in the urethra, straddle injury and stricture disease were correctly diagnosed by the sonographic urethrogram. No patient reported discomfort during the examination. The sonographic urethrogram provided valuable information about the luminal and extraluminal anatomy of the anterior urethra. Further long-term studies will be necessary to assess its ultimate diagnostic potential.
