Posterior Urethra

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.

Aim: To evaluate the effectiveness of SonoVue urethrosonography in diagnosing the adult male anterior urethral strictures pathology in comparison with retrograde urethrography.Material and method: We standardised the method and performed a comparative study evaluating the diagnosis of urethral strictures using retrograde urethrography and retrograde ultrasonographic exploration with SonoVue on 6 male patients.Results: In all patients, the existence of urethral stricture, localization and its extension were confirmed. Contrast-enhanced ultrasonographic exploration brought additional categories of information: the degree of spongiofibrosis, the elasticity of the urethral walls and the presence of urethral lithiasis. There were no periprocedural incidents.Conclusion: This pilot study demonstrates the feasibility and innocuity of urethral ultrasound with SonoVue. Real-time ultrasound exploration highlights aspects that are not seen in radiological examination, so the method can be complementary or alternative to this procedure.

The aim of the present study is to describe and evaluate a new technique for performing Computed-Tomography Retrograde Urethrography (CT-RUG). Males with urethral anomalies detected by retrograde urethrography (RUG) and/or retrograde sonourethrography (RSUG) underwent CT-RUG using the clamp method and three radiologists evaluated the anomalies in each technique separately and blindly. CT-RUG was done successfully in all the cases (n = 22), with means of 6 min duration and 95 mL of contrast; no pain was reported by 81% of the patients (VAS: 0) and very mild pain by the rest (VAS: 0.5–1.2). CT-RUG showed better diagnostic efficacy in cases of periurethral fistula (n = 8), urethral stent (n = 3), previous urethroplasty and urethral lithiasis (n = 2), a similar accuracy to RSUG for measuring the length of anterior urethral strictures (n = 9) and greater accuracy than RUG (p = 0.008). Six cases received 2 CT sweeps, with an effective dose of 4.96 mSv, and the remaining 16 had 1 sweep and received 3.456 mSv. To the best of our knowledge, this is the first study to describe the clamp method for CT-RUG, a method that is effective and comfortable for both the patient and the operator (retrograde infusion of contrast).
