CT voiding cystourethrography using 16-MDCT for the evaluation of female urethral diverticula: initial experience

Abstract

Conventional voiding cystourethrography (VCUG), transvaginal sonography (TVUS), and MRI have been used for the evaluation of urethral diverticula [1–7]. These imaging techniques, however, rarely identify the exact location of the ostium of a diverticulum in the urethra, which is the most important information for urologists who plan surgery [8, 9]. We report our initial experiences with CT VCUG using 16-MDCT for the evaluation of female urethral diverticula. With this technique, the accurate locations of the ostia of diverticula were clearly shown, which was not possible with conventional VCUG, TVUS, or MRI. CT VCUG is a useful imaging technique for the evaluation of urethral diverticula and may replace conventional VCUG, TVUS, or MRI for this purpose.
