In a modified lithotomy position (supine position with elevated legs), probands will get an examination of their pelvic floor by using a common ultrasound probe head on the perineum. During the examination, the bladder should be filled with around 300ml. If patient appear with empty bladder, the examination can be repeated on an other date. During the examination, the pelvic floor will be observed during rest, coughing and valsalva-maneuver. One examination takes around 30minutes. During ultrasound, we want to illustrate the urethral mobility, the bladder neck opening and the urethral angle as well as the distance from the urethra to the symphysis.
