Cystitis is a term that refers to urinary bladder inflammation that results from any one of a number of distinct syndromes [1]. It is most commonly caused by a bacterial infection in which case it is referred to as a urinary tract infection.[2]

Signs and symptoms

Differential diagnosis

There are several medically distinct types of cystitis, each having a unique etiology and therapeutic approach:

  • Traumatic cystitis is probably the most common form of cystitis in the female, and is due to bruising of the bladder, usually by abnormally forceful sexual intercourse. This is often followed by bacterial cystitis, frequently by coliform bacteria being transferred from the bowel through the urethra into the bladder.
  • Interstitial cystitis (IC) is considered more of an injury to the bladder resulting in constant irritation and rarely involves the presence of infection. IC patients are often misdiagnosed with UTI/cystitis for years before they are told that their urine cultures are negative. Antibiotics are not used in the treatment of IC. The cause of IC is unknown, though some suspect it may be autoimmune where the immune system attacks the bladder. Several therapies are now available.
  • Eosinophilic cystitis is a rare form of cystitis that is diagnosed via biopsy. In these cases, the bladder wall is infiltrated with a high number of eosinophils. The cause of EC is also unknown though it has been triggered in children by certain medications. Some consider it a form of interstitial cystitis.
  • Hemorrhagic cystitis, can occur as a side effect of cyclophosphamide, ifosfamide, and radiation therapy. Radiation cystitis, one form of hemorrhagic cystitis is a rare consequence of patients undergoing radiation therapy for the treatment of cancer.
  • In sexually active women the most common cause is from E. coli and Staphylococcus saprophyticus.

Diagnostic approach

  • A urinalysis commonly reveals white blood cells (WBCs) or red blood cells (RBCs).
  • A urine culture (clean catch) or catheterized urine specimen may be performed to determine the type of bacteria in the urine and the appropriate antibiotic for treatment.


Treatment

Treatment depends on the underlying cause.
