To determine the prevalence of interstitial cystitis in Japan, and to analyse the diagnostic criteria and treatments most commonly used by Japanese urologists. Materials and methods Questionnaires were sent to 300 urologists at major hospitals, including medical university hospitals, throughout Japan, asking about the number of patients with interstitial cystitis, its epidemiology, diagnosis and therapy.
The prevalence of interstitial cystitis was 1.2 per 100 000 patients and 4.5 per 100 000 female patients; the male/female ratio was 1 : 5.8. Most Japanese urologists used two or more diagnostic criteria; bladder biopsy was the most common diagnostic method. Dimethyl sulphoxide instillations and corticosteroids were the most frequently used therapies.
The prevalence of interstitial cystitis in Japan is markedly lower than that reported in Europe and North America. The reasons for this difference were not only racial but also the lack of awareness among Japanese urologists and patients about interstitial cystitis.
确定日本间质性膀胱炎的患病率，并分析日本泌尿外科医生最常用的诊断标准和治疗方法。材料与方法向日本各大医院（包括医科大学附属医院）的300名泌尿外科医生发送调查问卷，询问间质性膀胱炎患者数量、流行病学、诊断和治疗情况。
间质性膀胱炎的患病率为每10万名患者中有1.2例，每10万名女性患者中有4.5例；男女比例为(1:5.8)。大多数日本泌尿外科医生使用两种或更多诊断标准；膀胱活检是最常用的诊断方法。二甲基亚砜灌注和皮质类固醇是最常用的治疗方法。
日本间质性膀胱炎的患病率明显低于欧洲和北美的报道。这种差异的原因不仅在于种族，还在于日本泌尿外科医生和患者对间质性膀胱炎认识不足。
