In a recent scientific study on overactive urinary bladder syndrome, researchers used the term "latchkey incontinence" to describe "the loss of urine that occurs when one arrives home and puts the key in the lock of one's front door." From MEL Magazine:
According to Jamin Brahmbhatt, a urologist in Florida, peeing is a much more complex dance between the mind and body than you might think. "The ability to control how you urinate requires a balance between the muscles and your nerves around your bladder and your urethra working in synch," he explains. "Some of these functions happen automatically, and some require manual control by the muscles that you naturally control. So when urine is filling up inside your bladder, your bladder naturally expands. When you go to the bathroom, your sphincter around your urethra will relax and your bladder will start to squeeze. This process sounds simple, but it does require the muscles around your urethra, which we call your pelvic floor, to all work and synch."
He continues, "To keep your bladder healthy, I recommend my patients empty their bladder before they start having extreme 'got-to-go' feelings. There's only so much the bladder can tolerate, and this process gets more complicated with the presence of a prostate, which naturally grows as men get older. All these processes can also be affected by diabetes, strokes, infections and many other medical problems."
