A Study of Normal Renal Blood Perfusion Using Ultrasonography

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.
