UROFLOWMETRY AND CLINICAL MEANING

緒言

　排尿状態を客観的に知ることの臨床的意義は，排尿障害患者の診断と治療効果の判定に有用な方法として多くの人に認められるようになつた。著者らは，かつてKaufman^1）型のuroflowmeter（排尿流力測定器）を使用して排尿流力を測定したことがある^2）。現在では，非常に精巧な装置も市販されているが，今回は，Koontzら^3）の報告する簡単な装置で，かつ操作も容易なurofiowmeterを，昭和43年7月より使用してきたので，その成績の一端を報告する。

Urinary flow was examined in 152 healthy cases by the cylinder type uroflowmeter reported by Koontz and Rowax. The maximum voiding rate per second were as follows; 25.8 ml/sec among maleand 29.6 ml/sec among female between 20 and 40 years, 22.6 ml/sec among male and 28.2 ml/sec among female between 41 and 56 years, 18.7 ml/sec among male and 22.3 ml/sec among female above 57 years of age.

The maximum voiding rate (MVR was 7.9 ml/sec in 29 cases (57~77 years) with benign prostatic hyperplasia but the average MVR in 4 cases who underwent prostatectomy was 18 to 26 ml/sec, which was almost the same as those in the prime of life.
