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.
How often you pass urine depends on how much urine is produced as well as how much urine the bladder will hold. If you drink 1.5 litres a day and your bladder normally holds 400 millilitres (ml), then you will empty your bladder approximately four times that day. A bladder that holds only 100 ml results in passing urine 15 times. If you drink twice as much, you will need to empty your bladder twice as frequently. Normal frequency of voiding is up to seven times a day or not more than every two hours. In young women, the bladder normally holds 400 to 600 ml and is usually emptied when holding 250 to 400 ml. As people age, their bladder capacity tends to decrease, leading to increased frequency of micturition (voiding), especially at night.
