Figure 3. Montage of sagittal frame capture images from the descending urethrosonographic video of a patient with uncorrected hypospadias. The more proximal images are obtained with the penis "pinched", the urethra (asterisk) distended and insonated from the ventral surface. The distal image of the tip of the penis is obtained during micturition insonated from the dorsal surface. The ventral urethral meatus is clearly demonstrated (arrow) with a more proximal irregular narrowing (arrowheads), which did not impede the flow of urine. The thin echogenic line (curved arrow) bordering the anechoic column of urine represents the urethral mucosa.
