Maybe to understand urinary incontinence it might be helpful to know how the bladder works. Actually he bladder is a stretchy muscular bag that collects and stores urine. It sits in the pelvis at the lowest point in the abdomen, immediately behind the pubic bone.
The bladder is constantly receiving urine from the kidneys, which filter it down to the bladder through tubes called ureters. The urine is held in the bladder by the pelvic floor muscles, which keep the urinary opening (urethra) closed.
Once the bladder is full, a signal is sent to the brain that triggers the need to pass urine. At a suitable time, the brain then tells the pelvic floor muscles to relax and the bladder contracts to push the urine out.
It is when this process is interrupted which can be in several different ways, that problems with urinary incontinence can occur.
