Sonourethrography in the Evaluation of Anterior Urethral Strictures

Purpose: To determine the reliability of sonourethrography (SUG) in the evaluation of male anterior urethral strictures. Materials and Methods: Both SUG with retrograde saline infusion and retrograde urethrography (RUG) were performed in 5young normal volunteers and 20 patients with symptoms of impaired urine flow. Those findings were compared with u rethroscopic and operative fi nd ings in a 11 patients. Results: SUG was more accurate in the evaluation of the stricture length and degree than R UG in 7 patients with anterior urethral strictures, when compared with their subsequent open urethroplasty findings. Only SUG could classify the degree of spongiofibrosis surrounding the strictures in 15 patients. So, SUG was diagnostically as efficacious as or, superior to, RUG in all 20 patients. Conclusion: SUG can be used as one of complementary and reliable tools for diagnosis, evaluation and follow-up of anterior urethral strictures.
