Synchronous urinary flow and pressure studies were done on 51 male adults consiting of 12 normal subjects and 39 patients with varying degrees of bladder outlet obstruction due to benign prostatic hypertrophy. Mean maximum detrusor pressure levels of 50 mm. Hg and above were found to be indicative of bladder outlet obstruction. Elevated mean maximum detrusor pressure fell preoperatively within normal limits after prostatecomy. Chronic retention of urine was not associated with poor contraction of the detrusor muscle. Clinical findings of obstruction were shown to be inadequate for estimation of maximum detrusor pressure. Recording the detrusor pressure was found to be a better urodynamic test for bladder outlet obstruction than recording the urinary flow rate. Recording urinary flow is, however, a simple test and should remain a screening test for impaired drainage of the bladder outlet.
对51名成年男性进行了同步尿流和压力研究，其中包括12名正常受试者和39名因良性前列腺增生导致不同程度膀胱出口梗阻的患者。发现平均最大逼尿肌压力水平达到50毫米汞柱及以上表明存在膀胱出口梗阻。术前前列腺切除术后，升高的平均最大逼尿肌压力降至正常范围内。慢性尿潴留与逼尿肌收缩不良无关。结果表明，梗阻的临床体征不足以估计最大逼尿肌压力。与记录尿流率相比，记录逼尿肌压力是一种更好的用于检测膀胱出口梗阻的尿动力学检查方法。然而，记录尿流是一项简单的检查，应继续作为膀胱出口引流受损的筛查检查。
