The Absence of the Verumontanum at Voiding Cystourethrography as a Sign of Prostate Maldevelopment
Figure 1
Voiding cystourethrography, magnetic resonance imaging, and urethroscopy in prune-belly syndrome. (a) In a 2-month-old child, the voiding phase of cystourethrography shows a large bladder neck without VM salience in the posterior urethra. (b) In the same patient at the age of 10, T2-weighted axial scan shows the absence of the right deferent and seminal vesicle, while the left seminal vesicle is tubular (black arrow) and the prostate gland is not detected. (c) Urethroscopy confirms the verumontanum hypoplasia, which is quite appreciable (arrows).
