[Kidney involvement and arterial hypertension in middle-aged and elderly subjects].

The examination covered 125 elderly and senile subjects (106 females and 19 males) which made up 90.6% of those living in the boarding house. Their mean age was 81.3 years. Arterial hypertension was detected in 61.6% of the examinees. 18.5% of the examinees had hyperuricemia. Concentration function of the kidneys was affected in all the examinees. Half of them exhibited a moderate rise in the level of blood creatinine. The authors discuss the relationship between high prevalence of arterial hypertension, its tendency to crises and involutional processes in the kidneys in the onset and development of renoprival condition.
