Abstract
Fifty-eight men with prostatism, aged 58-75 yr, were studied 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. Apparently 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: moderate to severe prostatic enlargement with severe obstruction; moderate to severe prostatic enlargement with minimal or no obstruction and minimal prostatic enlargement with severe obstruction. A good correlation became apparent between micturitional vesicourethral static pressure profilometry and uroflowmetry.
