DO THE NATIONAL INSTITUTE OF DIABETES AND DIGESTIVE AND KIDNEY DISEASES CYSTOSCOPIC CRITERIA ASSOCIATE WITH OTHER CLINICAL AND OBJECTIVE FEATURES OF INTERSTITIAL CYSTITIS?

However, the 2 groups had similar urine markers and bladder biopsy findings. The cystoscopic criteria do not appear to identify a distinct pathophysiological subset of patients with IC symptoms.
