Abstract:
This is a cross sectional descriptive study was done to investigate the utility of
Doppler ultrasound in detecting the range of spectrum of the renal arteries of the
healthy kidneys. A sample of 50 patients of different gender and age group were
selected, Their age range (19-80 years) Male 26 (52%) Females 24 (48%) the
study was carried out at Ibn Elhaitham diagnostic centre, during the period of three
months. The resistive index (RI), peak systolic velocity (PSV) and pulstality index
(PI) of renal arteries (segmental arteries) of the patients were taken to get the range
of these values in healthy kidneys of sudanese population. The result was that;
maximum number of individuals almost 42% were having the PSV values in the
moderate range of 20.6-40.1 cm/s. 52% of individuals were having RI values in the
range of 0.56-0.62 .36% of individuals were having the pubtality index(PI) values
in the rang of 0.90-1.54 which was the maximum number of individuals. In
conclusion spectral reassessment of renal arteries is one of the most valuable tool
for detecting any renal vascular pathology, even in healthy kidneys, the upper
limits of the normal values may be alarming for any hidden problem.
