How is IC / PBS diagnosed?

Because symptoms are similar to those of other disorders of the urinary bladder and because there is no definitive test to identify IC / PBS, doctors must rule out other treatable conditions before considering a diagnosis of IC / PBS. The most common of these diseases in both genders are urinary tract infections and bladder cancer. IC / PBS is not associated with any increased risk in developing cancer. In men, common diseases include chronic prostatitis or chronic pelvic pain syndrome.

The diagnosis of IC / PBS in the general population is based on

presence of pain related to the bladder, usually accompanied by frequency and urgency

absence of other diseases that could cause the symptoms
Diagnostic tests that help in ruling out other diseases include urinalysis, urine culture, cystoscopy, biopsy of the bladder wall, distention of the bladder under anesthesia, urine cytology, and laboratory examination of prostate secretions.
