[Non-stenotic anterior urethral lesions. Diagnosis by echographic urethrography].

The results of a study using sonographic urethrography, radiologic retrograde urethrography and urethroscopy to evaluate 11 different types of non-stenotic lesions of the urethra are presented. Sonographic urethrography accurately diagnosed all of the findings and radiologic retrograde urethrography had 7 false negatives. Based on the foregoing results, we advocate the use of sonographic urethrography as a valid alternative in the evaluation of non-stenotic urethral lesions.
