[Regional hemodynamics of the penis in erectile impotence]

Regional hemodynamics of the penis is an essential part in the complex investigation of patients with erectile impotence. It is an actual problem to find diagnostically valuable noninvasive techniques allowing one to make a reliable assessment of penile erection mechanisms in various groups of the patients. In this line the authors faced the problem to find out the diagnostic value of dopplerography in measuring the linear rate of the blood flow (LRBF) in the penile arteries during the complex study of penile hemodynamics with regard to various groups of patients. The authors employed the following techniques: measurement of penile systolic pressure; determination of the penile-brachial index; rheophallography and determination of rheographic index; dopplerography and LRBF measurements. A total of 60 males were under study: group I--controls (20 males); group II--sexologically compromised patients without any disease of major vessels; group III--patients with Leriche's syndrome. The findings were analysed in variance. The coefficient of paired correlation was derived. Comparing each parameter between the groups showed a significant difference in each method between groups 2 and 3, as for parameters, only LRBF varied greatly in these groups.
