Abstract
Two cases are both females. Case 1 is 56 years old, and Case 2 is 28 who were diagnosed as interstitial cystitis. Only Case 1 had associated bladder pain. We used the frequency/volume chart to make clear one's pathology. In Case 1, the interval of voiding time and the voided volume were almost equal. In Case 2, there was some nocturia and the voided volume was variable. These results showed that Case 1 had organic disorder as its major pathology, and Case 2 had a functional disorder. As for the treatment, hydrodistension was effective in Case 1, and bladder training in Case 2. Interstitial cystitis has the mixed pathology of organic and functional disorder. The frequency/volume chart and the presence of bladder pain help us to understand the major pathology and treatment of interstitial cystitis. With regard to a case which seems to be a functional disease, we need to differentiate interstitial cystitis from chronic pain disorder or psychogenic urgency-frequency syndrome.
