Figure 1

Dynamic mid-sagittal MRI after robot-assisted radical prostatectomy (RARP): at rest (A) and with abdominal pressure (B). The distance from the lowest point of the pubic bone to the anterior edge of the rectal wall (PB-AR, two-headed red arrow) was measured at rest and with abdominal pressure (large green arrow). The external urethral sphincter is indicated by the box surrounded by the blue dashed line. The anterior edge of the rectal wall is indicated by a yellow dashed line. The bladder base at rest is indicated by an orange dashed line. Each red cross is each urethrovesical junction (UVJ) at rest (A) and with abdominal pressure (B). The UVJ is positioned using the line that connects the superior border of the pubic bone and the lower sacrum (red dashed line) as an index. The small green arrow indicates UVJ movement.
