Multiple urinary flow recordings were carried out on 51 men and without bladder outlet obstruction due to benign prostatic hypertrophy. All patients were over 50 years of age. Six urinary flow patterns (types 0-5) were defined. Types 0-3 were found in patients without obstruction, while all six patients were observed in those with clinical obstruction. Following prostatic surgery, only types 1, 2 and 3 were found. Only type 5 flow pattern can be determined by flow rate alone because it is by definition on the curve obtained when peak flow rate is below 4 ml per second. In this study, no type of flow pattern was characteristic of bladder outlet obstruction due to benign prostatic hypertrophy. The supposedly characteristic type of flow pattern in this clinical condition reported by earlier workers is mainly a result of a difference in the age distribution between their control and test groups.
对51名无因良性前列腺增生导致膀胱出口梗阻的男性进行了多次尿流记录。所有患者年龄均超过50岁。定义了六种尿流模式（0 - 5型）。0 - 3型见于无梗阻患者，而所有六种模式均在有临床梗阻的患者中观察到。前列腺手术后，仅发现1、2和3型。仅5型尿流模式可仅通过流速确定，因为根据定义，它是在峰值流速低于每秒4毫升时获得的曲线上的情况。在本研究中，没有一种尿流模式是良性前列腺增生导致膀胱出口梗阻的特征性表现。早期研究者报道的这种临床情况下所谓特征性的尿流模式主要是其对照组和试验组年龄分布差异的结果。
