N30: Cystitis

N30.2: Other chronic cystitis

The bladder sits low down in the abdomen and collects the urine. The urine is produced in the two kidneys. The urine flows from the kidneys into the bladder via the ureters. When you pass water, the urine flows from the bladder via the urethra and out. The inside of the bladder is lined with a protective mucosal layer.

Your bladder is inflamed from time to time or permanently. Bladder inflammation can be caused or aggravated by things like foreign bodies such as a tube in the bladder or repeated contact with pathogens.

People with an inflamed bladder sometimes experience pain when urinating and pain in the lower abdomen. It also possible that you will have a frequent urge to go to the toilet.
