We studied 58 men with prostatism, who were between 58 and 75 years old, with micturitional vesicourethral static pressure profiles. The study consisted of recording static (lateral) pressures of successive segments of the posterior urethra during voiding, with synchronous monitoring of the vesical pressure activity. An abnormal pressure decrease across the supramontane urethra was considered to be a functional compromise to the prostatic urethra. The studies indicated that the degree of prostatic urethral obstruction was not related to the clinical and endoscopic assessment of prostatic enlargement. Three major patterns emerged from our studies: 1) moderate to severe prostatic enlargement with severe obstruction, 2) moderate to severe prostatic enlargement with minimal or no obstruction and 3) minimal prostatic enlargement with severe obstruction. Also, a good correlation became apparent between micturitional vesicourethral static pressure profilometry and uroflowmetry.
我们研究了58名患有前列腺增生的男性，他们年龄在58至75岁之间，具有排尿时膀胱尿道静压曲线。该研究包括在排尿过程中记录后尿道连续节段的静态（侧向）压力，并同步监测膀胱压力活动。跨前列腺尿道的异常压力降低被认为是前列腺尿道的功能受损。研究表明，前列腺尿道梗阻程度与前列腺增生的临床和内镜评估无关。我们的研究出现了三种主要模式：1）中度至重度前列腺增生伴严重梗阻，2）中度至重度前列腺增生伴轻度或无梗阻，3）轻度前列腺增生伴严重梗阻。此外，排尿时膀胱尿道静压测量法与尿流率测定法之间也呈现出良好的相关性。
