Parts of the bladder control system
Bladder control depends on muscles working together when the bladder is filling with urine. The bladder muscle should be relaxed and the muscles around the urethra (the tube that urine passes through), called the pelvic floor muscles, should be tight. Exercises that strengthen the pelvic floor muscles can help hold urine inside the bladder, preventing leakage. These pelvic floor muscle exercises are commonly called "Kegel" exercises, named after the doctor who developed them.
