下部尿路における排尿の水力学的研究 第1編: 排尿流力測定(とくに最高排尿比について)

Abstract

Uroflometry has been well accepted as an objective method to examine the state of voiding. The author devised a type of urofiometer, with which uroflometric studies were carried out. 1) Uroflometry was found to be a simple and objective method to detect abnormal voiding. 2) Uroflometry of 153 normal males voiding more than 200 ml showed the maximum voiding rate (MVR) to be greater than 18 ml/sec. Low MVR was suggestive of disturbance of urination. 3) Improvement of MVR was observed after prostatectomy in 15 cases and urethral dilatation in 6 cases. 4) Uroflometry was useful to know the potential ability to void in 37 cases of prostatic diseases and 6 cases of urethral stricture. It was also informative for establishment of the clinical judgment as to treatment. 5) Uroflometry was applicable to know the effectiveness of dilation for urethral stricture.
