Intermittent catheterization vs Indwelling catheters

When the bladder is unable to empty properly, your doctor may recommend you insert a catheter to allow urine to exit the body.  Intermittent catheterization refers to inserting a catheter into the bladder via the urethra intermittently, commonly every 4-6 hours.  This is in contrast to an indwelling catheter such as a foley or suprapubic, which stays inside the body at all times and allows continuous drainage of urine.

While urinary tract infections (UTIs) are still possible with intermittent catheterization, clinical studies have shown that there is a much greater risk for UTIs with indwelling catheters.  This should make sense because of the constant connection to the outside of the body which can allow bacteria to make its way inside the urinary tract.  With intermittent catheterization, a catheter is inserted just long enough to empty the bladder and then removed.  The less time the catheter is inside the body, less chance for an infection.

While there are advantages and disadvantages to each method of draining the bladder, you should discuss all options with your doctor so that the best treatment plan can be chosen for your individual needs.  For those needing to self-catheterize, check out our guide for men and guide for women on intermittent catheterization.
