Radiographic retrograde urethrography (RUG) has traditionally been the preferred technique used by urologists to image the anterior urethra. Since originally described by McAninch et aL in 1988, ultrasonic imaging of the urethra has evolved into a powerful and clinically useful tool for the accurate delineation of urethral pathology. However the posterior urethra cannot be assessed reliably using this technique. Sonourethrography has proved to be more accurate than conventional radiographic urethrography in measuring stricture length throughout the anterior urethra. The objective and purpose of this study was to assess the efficacy of sonourethrography in the evaluation of anterior urethral strictures and also to explain its many advantages over traditional imaging technique.
