Urethral hypermobility refers to too much movement of the urethra, causing it to drop below the pelvic floor muscles during certain activities. This may or may not cause urine leakage.
When the support provided by the pelvic muscles is relaxed or lost, the bladder neck and urethra may shift, sag, or drop into a lower position during periods of activity, thus causing pressure on the bladder neck area. The pressure on the bladder will exceed the pressure on/in the urethra. If the bladder neck or urethra opens briefly, leakage occurs.
