Abstract

PURPOSE: Urologists will benefit from an imaging modality which can assess intra and extraluminal characteristics of urethral strictures. We conducted a prospective pilot study evaluating the utility of contrast-enhanced ultrasound and shear wave elastography for the evaluation of bulbar urethral stricture disease.

MATERIALS AND METHODS: Patients with a single, bulbar urethral stricture were prospectively recruited. Contrast-enhanced ultrasound and shear wave elastography were performed at the time of surgical repair and at 4 months' followup using an Aplio i800 scanner (Canon Medical Systems, Tustin, California) with an i8CX1 transducer. Sulfur hexafluoride lipid-type A microsphere ultrasound contrast (Lumason®, Bracco Imaging, Princeton, New Jersey) was injected retrograde through the urethra. Stiffness of the corpus spongiosum was measured at and adjacent to the stricture site. Stricture lengths based on retrograde urethrogram, grayscale ultrasound and contrast-enhanced ultrasound were correlated with measured intraoperative stricture length.

RESULTS: Thirty men were enrolled. Contrast-enhanced ultrasound (R

CONCLUSIONS: This pilot study demonstrates the ability of contrast-enhanced ultrasound and shear wave elastography to become safe, accurate, and potentially efficacious modalities for assessing bulbar urethral strictures and spongiofibrosis.
