Diagnosis of a female urethral diverticulum using transvaginal contrast-enhanced sonourethrography.

The diagnosis of female urethral diverticulum is difficult due to its nonspecific symptoms, and invasive diagnostic procedures are often necessary. We report a case in which the diagnosis was made with contrast-enhanced transvaginal sonourethrography. The microbubble contrast agent could be seen filling the diverticular cavity via its opening.
