This article presents and evaluates the symptoms, presentation, diagnosis,
and treatment of men with interstitial cystitis (IC). A retrospective chart
review and an interview of all men in our practice diagnosed with IC since
1990 was performed. The patients' presenting symptoms, physical findings,
clinical evaluation, and responses to therapy were reviewed. A total of 52
men were identified during the study who met the National Institute of Diab
etes and Digestive and Kidney Diseases (NIDDK) criteria for diagnosis of IC
. The most common referral diagnosis was prostatitis with the most common p
redominant symptoms being suprapubic pain with urinary frequency and dysuri
a. A significant number of male patients also developed sexual dysfunction.
All patients met the NIDDK criteria for a diagnosis of IC, Multiple therap
ies were used for the treatment of these patients over the study period. Fi
ve patients were initially treated with dimethyl sulfoxide (DMSO) as a sole
agent; however, all intravesically treated patients eventually failed this
form of therapy. A total of 37 of 52 patients were treated with multidrug
oral therapy. Findings showed that 80% of patients achieved > 75% improveme
nt in their symptomology at 6 months of follow-up with a durable response a
t 1 year. IC in men is probably underdiagnosed and is most commonly misdiag
nosed as prostatitis, The patient's presentation is analogous to that in th
e female population allowing for gender differences. The patients responded
well to multidrug oral therapy. (C) 2001, Elsevier Science Inc.
