We studied uroflowmetry in 25 normal adult males and 100 patients with benign prostate hypertrophy (BPH). We planned a new parameter, named average flow rate increase ratio (AFRIR), based on urinary flow rate curve. One hundred patients with BPH were measured presumed circle area ratio (PCAR) based on transrectal ultrasonotomography and performed comparative studies. AFRIR was not related to voided volume of urine (VV). Although AFRIR in 100 patients with BPH was not significantly different from that in 25 normal adults males, AFRIR in 20 patients with BPH, needing surgical operation, was significantly lower than that in 25 males. We considered that AFRIR was useful for deciding on the surgical operation and these levels were below 1.5 ml/sec2. AFRIR was correlated well with maximum flow rate (MFR), average flow rate (AFR), MFR/VV x 100, AFR/VV x 100, PCAR and Area, respectively. PCAR correlated well with MFR/VV x 100 and AFR/VV x 100, respectively. Area correlated well with MFR, MFR/VV x 100, respectively. From these results, it was presumed that AFRIR was reflected clearly to the condition of urine voiding.
我们对25名正常成年男性和100例良性前列腺增生（BPH）患者进行了尿流率测定。我们基于尿流率曲线设计了一个新参数，称为平均流速增加率（AFRIR）。对100例BPH患者进行经直肠超声断层扫描测定假定圆面积比（PCAR）并进行比较研究。AFRIR与排尿量（VV）无关。虽然100例BPH患者的AFRIR与25名正常成年男性的AFRIR无显著差异，但20例需要手术治疗的BPH患者的AFRIR显著低于25名男性。我们认为AFRIR对决定手术治疗有用，且这些水平低于1.5ml/sec²。AFRIR分别与最大流速（MFR）、平均流速（AFR）、MFR/VV×100、AFR/VV×100、PCAR和面积密切相关。PCAR分别与MFR/VV×100和AFR/VV×100密切相关。面积分别与MFR、MFR/VV×100密切相关。从这些结果推测，AFRIR能清楚地反映排尿情况。
