Usage of catheters or the procedure of using catheters is termed is catheterization, where there is an insertion of a catheter (for men) through the urethra and into the bladder for proper withdrawal of urine. The urine is collected or drained into a closed bag.

The purpose of catheters for men is to help those who cannot urinate normally anymore. To help men who cannot urinate properly anymore, there are two procedures.

Providing care for patients who have terminal illness or severe injury
For managing ulceration in the skin
To maintain continuous urine movement or outflow for patients who are undergoing surgical procedures
Used as a part of the preparation for urologic surgery
To provide relief to patients who have earlier had urinary retention

Men who use intermittent catheters may take some time to get used to this urinary procedure. The time taken to adjust to this procedure is because the urination process is no longer how it normally is and with catheters for men, the urination process is slow as different. However, gradually a person gets used to it.

Antibiotics are not prescribed when catheters are used. This is a preventive measure for men who are at risk of urinary tract infection. For prevention from other infections, the extended portion of catheter must be cleaned properly using a mild soap and warm water.

There are risks involved in the usage of catheters for men. There is a risk of certain complications such as:
Infection caused by bacteria in the urinary system
trauma caused to the bladder or urethra by incorrect usage or insertion of catheter while the balloon is inflated. When this trauma is repeated, it can cause scarring of the urethra or even narrowing of the urethra.
Leakage of urine when the size is not proper. This problem, however, can be solved by changing the size of the catheter.
