Measurement of urinary flow rate was carried out on 39 male patients with bladder outlet obstruction due to benign prostatic hypertrophy. All patients were over 50 years of age. Ten subjects, by clinical evaluation, had doubtful bladder outlet obstruction, nine had mild obstruction and 20 patients had moderate or severe obstruction. Four criteria were used for clinical diagnosis: obstructive symptoms, size of prostate by rectal digital exploration, volume of postmicturition residual urine and degree of bladder trabeculation seen on cystourethroscopy. Considerable inaccuracy results from basing the degree of impairment of urinary flow on the patient's obstructive symptoms, degree of prostatic enlargement, postmicturition residual urine or degree of bladder trabeculation. Severe obstruction symptoms generally indicate impaired urinary flow but the absence of obstructive symptoms does not exclude impaired flow.
对39例因良性前列腺增生导致膀胱出口梗阻的男性患者进行了尿流率测量。所有患者年龄均超过50岁。经临床评估，10名受试者膀胱出口梗阻情况存疑，9名有轻度梗阻，20名患者有中度或重度梗阻。临床诊断采用四项标准：梗阻症状、直肠指诊前列腺大小、排尿后残余尿量以及膀胱尿道镜检查所见膀胱小梁形成程度。基于患者的梗阻症状、前列腺增大程度、排尿后残余尿量或膀胱小梁形成程度来判断尿流受损程度会导致相当大的不准确性。严重的梗阻症状通常表明尿流受损，但没有梗阻症状并不排除尿流受损。
