Outpatient Ultrasound Urethrogram for Assessment of Anterior Urethral Stricture: Early Experience

ObjectiveTo describe the technique of ultrasound urethrogram (USUG) for the diagnosis of anterior urethral stricture performed in an ambulatory setting without any adjunctive imaging.Materials and MethodsBetween September 2013 and September 2015, 35 consecutive adult men (>18 years old) presenting for anterior urethral reconstruction underwent outpatient USUG prior to definitive management. No alternative imaging test was performed. Lengths of the strictures as determined by outpatient USUG and via direct intraoperative measurements were compared by a paired t test.ResultsStrictures were in the bulbar urethra in 24 men and in the penile urethra in 11 men. The differences between the outpatient USUG length measurements (mean = 1.86 cm) and the intraoperative stricture length measurements (mean = 2.02 cm) were not significantly different (P = .10). Additionally, the correlation coefficient between these length measurements was 0.84 (P < .001).ConclusionPreoperative USUG performed in the ambulatory setting for the diagnosis and characterization of anterior urethral strictures is safe and feasible. This outpatient imaging modality offers an alternative to retrograde urethrogram.
