Assessment of treatment outcomes of interstitial cystitis with hydrodistention and bladder training by O'Leary-Sant Interstitial Cystitis Symptom and Problem Indices

Objective: To investigate whether the O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) and Interstitial Cystitis Problem Index (ICPI) is efficacy measure tool for interstitial Cystitis (IC) treatment with hydrodistention (HD) and bladder training (BT). Materials and methods: From January 2003 to March 2006, 108 consecutive IC patients were treated by HD and BT after HD. This study evaluated the efficacy of treatment with the specific questionnaire for IC, the ICSI and ICPI. Each patient filled out the questionnaire before HD and three months after HD and BT. The efficacy of the treatment was evaluated using the average scores of ICSI and ICPI. Results: The mean ± margin of error, (95% confidence interval) of total scores of ICSI and ICPI were 13.89 ± 2.95, (13.33–14.45) and 12.51 ± 2.50, (12.04–12.98) before HD, respectively, and were 2.70 ± 1.16, (2.44–2.95) and 1.99 ± 1.27, (1.71–2.26) (all p < 0.005) three months after HD and BT, respectively. Conclusion: O'Leary-Sant ICSI and ICPI is not only a screening tool for IC but also a useful assessment tool for IC treatment outcomes.
