Inability to Urinate Overview. When you cannot empty your bladder completely, or at all, despite an urge to urinate, you have urinary retention. To understand how urinary retention occurs, it is important to understand the basics of how urine is stored in and released from the body.
When it's empty, your bladder is about the same size as an empty balloon. It looks like one, too! Then the bladder slowly fills up with the urine coming from the kidneys. When you have about a cup (237 milliliters) of urine in your bladder, your brain tells you it's time to find a bathroom. Once you're ready to pee, you relax a set of muscles at the bottom of your bladder. That lets the urine rush into the urethra, a tube that leads from your bladder out of your body.
