  • Title: Urodynamic evaluation of prostatic enlargements with micturitional vesicourethral static pressure profiles.
    Author: Yalla SV, Blute R, Waters WB, Snyder H, Fraser L.
    Journal: J Urol; 1981 May; 125(5):685-9. PubMed ID: 6164800.
    Abstract:
    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.
