Synchronous pressure and flow studies were carried out on 51 men over 50 years of age. The subjects were divided into groups based on degree of bladder outlet obstruction. Eight patients were also examined six to ten weeks after prostatectomy. Following multiple pressure and flow recordings, the mean premicturition resting intravesical pressure, the mean intravesical pressure at the commencement of voiding (the commencing intravesical pressure), the mean maximum intravesical pressure and the mean intravesical pressure at the end of voiding (mean cessation intravesical pressure) were determined for each subject. The maximum intravesical pressure varies in the same individual. A mean maximum intravesical pressure of 75 mm Hg and above indicates moderate or severe bladder outlet obstruction. However, this pressure is not of value in the determination of clinically doubtful or mild obstruction. None of the other intra-vesical pressures is of value in the diagnosis of bladder outlet obstruction. Six to ten weeks following successful prostatectomy the mean maximum intravesical pressure fell to normal limits.
对51名50岁以上男性进行了同步压力和流量研究。根据膀胱出口梗阻程度将受试者分组。8名患者在前列腺切除术后6至10周也接受了检查。在进行多次压力和流量记录后，确定了每个受试者排尿前静息膀胱内压均值、排尿开始时的膀胱内压均值（起始膀胱内压）、最大膀胱内压均值以及排尿结束时的膀胱内压均值（排尿终止膀胱内压均值）。同一个体的最大膀胱内压会有所变化。最大膀胱内压均值在75毫米汞柱及以上表明存在中度或重度膀胱出口梗阻。然而，该压力对于确定临床上可疑或轻度梗阻并无价值。其他膀胱内压力值对膀胱出口梗阻的诊断均无价值。成功进行前列腺切除术后6至10周，最大膀胱内压均值降至正常范围。
