Risk factors that affect the treatment of interstitial cystitis using intravesical therapy with a dimethyl sulfoxide cocktail - Abstract

INTRODUCTION AND HYPOTHESIS:Dimethyl sulfoxide (DMSO) bladder instillation is a standard therapy for interstitial cystitis (IC); however, there are varying degrees of success.

We hypothesize that first-line intravesical therapy with a DMSO cocktail will optimize treatment outcome.

METHODS: Ninety women with newly diagnosed IC were enrolled consecutively for the treatment. The IC symptom and problem index was used as an outcome measure.

RESULTS: Six (6.7%) patients dropped out of the treatment due to intolerable bladder irritation. Fifty-five (65.5%) of the remaining 84 patients, who completed the treatment, experienced ≧50% symptomatic improvement. After a regression analysis, three clinical variables were found to affect treatment adversely, i.e., the presence of advanced cystoscopic glomerulations, microscopic hematuria, and urodynamic detrusor underactivity, respectively.

CONCLUSIONS: Our results suggest bladder instillation with a DMSO cocktail may well be considered as first-line therapy for IC patients. However, there exists a subgroup of nonresponders who may have severe disease.
