The most prevalent feature of interstitial cystitis is irritative lower urinary tract symptoms, including urinary frequency in association with varying degrees of pain. The exact number of micturitions, daytime or nighttime, is not important; however, according to the National Institute of Diabetes & Digestive & Kidney Diseases (NIDDK) criteria, more than 8 micturitions per day is considered adequate for inclusion into clinical studies. [42] Daytime frequency in the absence of nocturia is not characteristic of interstitial cystitis. The absence of significant nocturia may suggest an alternative diagnosis (eg, sensory urgency). Urinary incontinence is quite rare. Patients with a primary complaint of incontinence may require further evaluation, including urodynamic studies.
