Sessions are twice a week for about six weeks, although it may take more than eight weeks to build up the muscles. More studies are needed to determine whether it has significant value. Catheters and Collection Devices Catheterization. Catheters are used mainly for cases of severe urge incontinence. Intermittent or temporary catheterization is usually the best choice.
Patients insert the catheter tube into their urethras, generally every three to four hours.
This type of catheterization carries few risks and empties the bladder completely. People who are mentally or physically incapable of self-catheterization may need permanent catheterization. The catheter is inserted by a doctor or nurse into the opening of the bladder and a cuff is inflated to hold the tube in place. Urine drains to an external collection device, which is generally strapped to the leg and must be emptied periodically. The procedure is not painful, but there is a substantial increased risk of infection.
