Figure 3

Perineal ultrasound image on midsagittal plane from a patient at rest. The positions of symphysis (S), urethra (U), bladder (B), ostium urethrae externum (MUE), meatus urethrae internum (MUI), reference line (X), and the line orthogonal to reference line (Y) are indicated. The urethral length is defined as a distance between MUE and MUI.
