Measurement of proximal urethra mobility: The outlines of the bladder and urethra were traced from lateral urethrocystograms at rest (gray line) and during Valsalva maneuver (black line). A line drawn between the middle of the urethra and the bladder neck defines the proximal urethra axis. The angle formed between the two axes defines proximal urethra mobility (102° in this example).
