When you don’t feel the urge to urinate, the bladder may become overfilled, and urine may start to leak out. You may also not completely empty your bladder, causing urine to back-up and overflow. This condition is called overflow incontinence, or sometimes called “chronic retention of urine” or “chronic urinary retention”.
Overflow incontinence often occurs as the result of a neurological condition that affects the nerves of the bladder, such as a spinal cord injury. Overflow incontinence can also occur in people who have trouble feeling when their bladder is full for reasons like diabetes or neuropathy. Overflow incontinence can also occur as the result of a blockage in the urethra or bladder, including a tumor, scar tissue, or (in men) an enlarged prostate or (in women) a dropped or prolapsed bladder. In both cases the bladder doesn’t empty well and continues to fill, and over time the muscles of the bladder become overstretched and lose some control.
Treatment and Management Techniques for Overflow Incontinence
Overflow incontinence can be a sign or symptom of a neurological condition or abnormal growth, so it is important that you seek medical diagnosis and treatment. Some treatment and management techniques that you might discuss with your healthcare professional are:
- Absorbent products
- Artificial sphincter surgery
- Catheterization
- Removal of obstruction
- Medications
- In men with an enlarged prostate (BPH): surgery on the prostate
- In women with prolapse: surgery for the prolapse or insertion of a pessary
- Sacral nerve stimulation
- Urine collection devices for men
