ABSTRACT
PURPOSE: To evaluate whether hydrodistention with fulguration of Hunner lesions (HD/FUL) plus maintenance dimethyl sulfoxide (DMSO) therapy prolongs the recurrence-free time in patients with Hunner type interstitial cystitis (IC).METHODS: The study enrolled patients with Hunner type IC who required repeat HD/FUL due to recurrence of IC symptoms after the first HD/FUL at our institution. All patients received a second HD/FUL plus maintenance DMSO therapy. The maintenance DMSO therapy was performed every 2 weeks for a total of 8 instillations, and then once every 4 weeks thereafter. The recurrencefree time from HD/FUL to therapeutic failure was estimated using the Kaplan-Meier method. The recurrence-free time between the first HD/FUL and second HD/FUL plus maintenance DMSO therapy was statistically compared using the log-rank test.RESULTS: A total of 21 patients (mean age, 66.3±10.8 years) with Hunner type IC were evaluated. The recurrence-free time for the second HD/FUL plus maintenance DMSO therapy was significantly longer than that for the first HD/FUL (P<0.0001). The median recurrence-free time for the first HD/FUL was 10.1 months, while that for the second HD/FUL plus maintenance DMSO therapy has yet to be reached. The recurrence-free rate for the first HD/FUL was 81.0% at 6 months, 38.1% at 1 year, 9.5% at 2 years, and 4.8% at 3 years. In contrast, the rate for the second HD/FUL plus maintenance DMSO therapy was 100% at 6 months, 94.7% at 1 year, 82.6% at 2 years, and 82.6% at 3 years. There were no significant differences in efficacy between the first and second HD/FUL.CONCLUSIONS: HD/FUL plus maintenance DMSO therapy clearly prolongs the recurrence-free time compared with HD/FUL alone in Hunner type IC.

Attempts were made to shorten the time required for checking up on data at the medical affairs department over special injection agents (expensive drugs, anti-cancer agents and blood products) used and at the same time to prevent missing claims for insurance money payment for these agents. For these purpose, the office work was systematized by using a computer software, which was easily available on the market. As a result, the amount yet to be claimed by oversight was reduced almost 90% from a year before. Our attempt was also crowned with success in boosting efficiency, thus contributing much to the management of our hospital.
