Colour Doppler ultrasonic investigation for determining the variation of blood flow in elderly people

ABSTRACT

Doppler ultrasound had been used for measuring kidney blood flow circulating KBFC on 360 subjects (720 kidneys). Depending on the age, in young men of control group, KBFC of male subject 1164.620 ± 184.932 ml/minute, of female 1235.00 ± 194.795 ml/minute, in both 2 gender 1199.811 ± 192.144 ml/minute. In comparing with the control subjects, the KBFC began to vary, decreased 6.91% in medium age subjects, in the senil subjects the decrease was obvious 11.79%, in the elderly: very obvious 27.27%. The age had had a strictly negative relation to KBFC variation.
