Abstract

1989年3月31日までの1年間に, 受診した499例について, 1)患者の年齢分布は3歳～88歳(平均年齢43歳)で, 20歳代が24%を占め最も多かったが, 30歳代から60歳代にかけても14～16%の年齢分布を示した.2)尿からの分離菌種はE. coliが圧倒的に多く(81%), ついで各種のStaphylococcus spp. (11%)が多かった.Staphylococcus spp.は夏期に多く分離される傾向があった.3)臨床症状として80%以上の症例が排尿痛, 残尿感, 頻尿を訴え, 初発症状として最も多いのは排尿痛(39%)であった.4)患者の訴えによる膀胱炎発症の誘因としては, 過労(131例), 排尿我慢(114例), 冷え(103例)が多く, 性交渉が発症誘因と回答したのは42例であった.5)「新婚膀胱炎」を経験した患者群は, 経験しない患者群に比べて, 最近3年以内の膀胱炎罹患率が有意に高かった

A total of 499 female patients with acute uncomplicated cystitis were observed and analyzed clinically for age distribution, characteristics of symptoms, bacterial culture of urine, behavioral aspects of recurrent cystitis and others. The patients were between 3 years and 88 years old (average: 43 years) and the majority of patients were from 20 to 69 years old. From 81.1% of the patients Escherichia coli was detected, followed by Staphylococcus spp (11.2%). The major symptoms were pain on urination (421 cases), urinary frequency (421 cases) and residual urine sensation (418 cases). The major causes of cystitis as reported by the patient were fatigue (131 cases), infrequent voiding (114 cases) and exposing the body to coldness (103); only 42 patients reported a relationship between sexual intercourse and cystitis. The patients who had been suffering from "honeymoon cystitis" were significantly inclined to be suffering from acute uncomplicated cystitis again in comparison with those who had not suffered from honeymoon cystitis. There was suggested to be a relationship between sexual intercourse and recurrent cystitis.
