title: Modified urodynamics for interstitial cystitis.
abstract: Interstitial cystitis (IC) is a poorly understood syndrome. Patients with pelvic pain, urgency, frequency, and/or dysuria may pose a diagnostic dilemma. They may have bladder-related symptoms or they may have nonbladder related symptoms. It is beneficial for the urologist to distinguish between these patients. This study outlined a modified urodynamics test to discriminate between bladder-related and nonbladder-related patients. Consecutive IC patients (bladder-related and nonbladder-related patients) and stress incontinent controls underwent modified urodynamics. Testing consisted of an epithelial leak test, a filling cystometrogram, bladder emptying and instilling lidocaine intravesically, and repeat cystometrogram after bladder emptying. The epithelial leak test and lidocaine test predict reliably if a patient has bladder-related or nonbladder-related symptoms. Modified urodynamics permits a logical stratification of IC patients, and may predict treatment response.
