Common Risk Factors And Causes Of Cystitis

Urinary Catheters

Catheters are thin tubes placed in the bladder to drain urine out of the body. They are used if individuals cannot urinate on their own to measure the amount of urine their body produces, or during some forms of surgery.

The use of urinary catheters is a significant risk factor for developing bacterial cystitis because using a catheter introduces bacteria into the bladder by allowing the bacteria to travel along the thin tube. Catheter use also promotes bacterial colonization by giving the bacteria a surface for adhesion and irritating the lining of the bladder. Between ten and thirty percent of patients who use a catheter even in the short-term develop bacteria in their urine. Catheters should always be inserted using a sterile technique and left in place only as long as necessary to reduce this risk.
