SU1251859A1 - Method of diagnosis of disturbances of hemodynamics in penis - Google Patents

Description

The invention relates to medicine, in particular to methods of functional methods for studying blood circulation, and can be used in surgical, urological and sexological practice.

The purpose of the invention is to reliably diagnose impaired regional blood flow by determining the power index of the regional blood flow.

The method is carried out as follows.

Four circular diameters of the diameter of an electrode made of graphitized tissue 7 mm wide each, fixed along the length of a narrow insulated plate with leads from each electrode, are fixed along the penis. Two extreme electrodes, one of which is in the base of the penis, the other at the head, are connected to current terminals,

and two medium ones - to the measuring terminals of the reoplethysmograph.

The tetrapolar longitudinal rheogram of the penis is recorded in the horizontal position of the subject after a deep, quiet exhalation with the baseline impedance (Z) of the test organ on the scale of the re-plethysmograph.

At the same time, the Tzapram pectoral (transthoracic) rheogram is recorded in the Kiibicek lead system. Simultaneously with recording longitudinal tetrapolar rheograms of the penis and chest, systolic blood pressure on the shoulder is measured, then systolic blood pressure in the vessels of the penis is measured by injecting air into the cuff to a level of 10–20 mm Hg. above the previously measured systolic pressure in the upper arm and the first pulse wave is recorded by the Doppler ultrasound (IPC-1) method.

On the resulting tetrapolar longitudinal rheogram of the penis, changes in impedance (iZ) are determined from the amplitude of the main curve, after which the specific pulse blood flow (Qp) is calculated according to the equation

Based on the obtained values, the index of regional blood flow capacity (s) is calculated as the product of the foam-and-covering index and the regional blood flow index.

Example. Patient S., 39 years old. Suffering from sexual dysfunction in the form of impaired vision.

The systolic blood pressure in the upper arm (110 mm Hg) was measured, and the rheogram of the chest and penis was recorded.

Systolic blood pressure in the vessels of the penis (I20 mm Hg) is measured.

Thus, the trial of the size of the IBI in patient S. does not indicate a lack of blood supply to the penis, while a pronounced decrease in the MI indicates its presence, and the magnitude of the MI reduction indicates the presence of profound, organic changes in the vessels that feed the pelvic organs. In connection with this, patient C. was subjected to selective pelvic angiography, which showed the presence of changes in the stenotic nature of the system of the internal and external iliac arteries on the left. These data confirm the results of non-invasive blood flow studies in the penis. The method was applied in the 7I study and in 43 patients. At the same time, the share of total blood flow is set to tO.

This allows one to quantify the blood supply to the organ, taking into account the individual characteristics and the state of the circulatory system, which significantly increases the reliability of diagnosis. Different numerical signs of access to one or another organ, allow to diagnose various forms of the disease, since power ultimately is the most
