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.
A healthy bladder can hold up to 16 ounces (2 cups) of urine comfortably. How frequently it fills depends on how much excess water your body is trying to get rid of. The bladder opens into the urethra, the tube that allows urine to pass outside the body. Circular muscles called sphincters close tightly to keep urine from leaking. The involuntary leakage of urine is called incontinence. Nerves in the bladder tell you when it is time to empty your bladder. When the bladder begins to fill with urine, you may notice a feeling that you need to urinate. The sensation becomes stronger as the bladder continues to fill and reaches its limit.
