Intermittent means something is done repeatedly and catheters are used to empty urinary bladders. Some patients have difficulty in completely emptying the bladder. This condition is called urinary retention and intermittent catheters are recommended to them in such cases. Urinary retention can be chronically caused by certain medications, obstruction of the urethra for varied reasons, and weakening of the bladder muscles due to aging. Intermittent catheters are inserted and removed multiple times a day instead of placement for a prolonged period, therefore, decreasing the risk of infections.
