Transrectal ultrasonography in the diagnosis of urethral diverticula in women.
The diagnosis of urethral diverticula in women can be difficult. Several imaging modalities have been described for evaluating this entity: urethrography; transabdominal, transrectal, transvaginal, and transperineal ultrasonography; computed tomography (CT); and magnetic resonance (MR) can be helpful in evaluating a diverticulum and its relationship to the urethra. We report on four women aged 36 to 42 years with urethral diverticula. Transrectal ultrasonography (TRU) was the most useful diagnostic test in our series. TRU showed 7 urethral diverticula and provided information about its shape, volume, and content as well as its spatial relationship about its shape, volume, and content as well as its spatial relationship to the urethra. In two cases, multiple diverticula were detected when only a single lesion was clinically suspected. Transabdominal sonography failed to demonstrate small diverticula. CT examination did not provide additional information except for the passage of the contrast from the urethra to the diverticulum in one of the cases. Voiding cystourethrogram was positive in only one patient.
