Transvaginal Sonographic Findings in Diagnosis and Treatment of Urethral Stricture

The prevalence of bladder outlet obstruction in women is variously reported to be from 2.7% to 8%. In a series in which the prevalence of urodynamic outlet obstruction was 6.5%, 13% of cases were secondary to urethral stricture. Urethral stricture or stenosis, which is rare in women, may be congenital or acquired. It may be due to traumatic injury from childbirth, vaginal surgery, or pelvic fracture or may be secondary to acute or chronic inflammation. The treatment of urethral stricture may include urethral dilation, internal urethrotomy, and urethral reconstruction. Transvaginal sonography (TVS), with its high-resolution visualization of the lower urinary tract, may aid in diagnosis and less invasive treatment of lower urinary tract disorders. We present the sonographic findings in a case of urethral stricture.
