Validity of superficial echography in the study of urethral pathology

In male patients routine examination for urethral disease includes retrograde and anterograde urethrography and urethroscopy. In the patients underwent radical cystectomy, detection of cancerous cells in the urethral washing suggest cancer relapse. Nowadays we can achieve a sonographic study of the anterior male urethra, using a superficial high frequency ultrasound probe. Since September 1992 till July 1993, 12 patients underwent cystectomy at our Institution and 13 patients affected by urethral stricture, have been investigated by routine examination and sonographic urethrogram. In the first group of patients, out of 3 patients with urethral tumor, sonourethrography has confirmed the presence of tumor in 2 cases. In these second group of patients, sonourethrography has located the stricture, evaluated the length, calculated the diameter of the stricture and the depth of fibrosis. Sonourethrography is a non-invasive method that can provide valuable information about the urethral lumen and the urethral wall.
