Three-dimensional computed tomography image. Three-dimensional computed tomography scan of a retrograde cystourethrogram reveals dilatation of the prostatic urethra (yellow arrow), a hypertrophic verumontanum (red arrow), bladder neck stenosis (green arrow), bladder distension with wall thickening, and vesicoureteral reflux with moderate ureter dilatation (blue arrows).

Three-dimensional computed tomography of a retrograde cystourethrogram revealed dilatation of the prostatic urethra, a hypertrophic verumontanum, bladder neck stenosis, bladder distension with wall thickening, and vesicoureteral reflux with moderate ureterohydronephrosis (Figure 1).
Urethroscopy. (A) Severe bladder neck contracture. (B) Prostatic urethra with longitudinal mucosal folds between the verumontanum and bladder neck.

Finally, cystourethroscopy revealed a normal penile and membranous urethra, but a dilated prostatic urethra with longitudinal mucosal folds between a hypertrophic verumontanum and bladder neck, which probably represented the least common type (type 2) of urethral valves and severe bladder neck contracture (Figure 2).
Voiding cystometrogram. A voiding cystometrogram performed 1 year postoperatively shows normal voiding with low pressures.
