METHOD OF DETERMINING INDEX OF FUNCTIONAL SUFFICIENCY OF CAVERNOUS TISSUE ARTERIAL BLOOD FILLING BY RESULTS OF PENIS ULTRASONOGRAPHY Russian patent published in 2011 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: ultrasonography of penis is performed. Volume of cavernous tissue (A) is determined by formula A(cm³)=S1×L1+S2×L2, where S1, S2 is transverse section of right and left cavernous body (cm²), L1, L2 is length of right and left cavernous body (cm). Volume rate of blood flow is determined by two cavernous bodies of penis (Q), carrying out measurements of volume rate of blood flow of all arteries, incoming and outcoming through tunica albuginea into cavernous bodies. Calculation of volume rate of blood flow by one artery is determined formula Vtot (cm³/min)=π×D/2×AvRate, where number π equals 3.14, D is artery diameter (cm²), AvRate is averaged rate of blood flow for three cardiac cycles (cm/min). Total volume rate of blood flow is determined by addition of volume rate of incoming and subtraction of outcoming arteries by formula V total (Q) (cm³ per minute)- V1+V2±V3±V4, etc. Index of functional sufficiency of cavernous tissue arterial blood filling is determined by formula K=Q:A.

EFFECT: method makes it possible to increase accuracy of diagnostics of vasculogenic erectile dysfunction due to estimation of functional sufficiency of arterial blood flow in cavernous tissue of penis.
