title: [Renal study protocol with ultrasonography: biometry and incidence of disease].
abstract: The present study establishes the size of the kidneys in adult males and females according to three age groups, under 30, 30 to 60, and over 60, in our community. To this end, morphologically normal kidneys were studied, considering four diameters: longitudinal (L), antero-posterior (AP), transverse (T) and cortical (D). We found that renal size, in all diameters, was larger in males and females, and the left one larger than the right one. The study include 522 kidneys, from a total of 247 subjects. Apart from renal biometry, the incidence of disease was also recorded. Ten different possibilities were included in the picture: 1) Normal (N); 2) Cysts (C); 3) Lithiasis (L); 4) Tumour (T); 5) Pyelonephritis (PN); 6) Acute Focal Nephritis (AFN); 7) Hydronephrosis (HN): 8) Double Excretory System (DES): 9) Abscesses (A); and 10) ther (O). The incidence of disease is maximal in subjects over 60, with predominance of women and left kidney; most frequent changes were cysts and pyelonephritis. Of the three age groups, those under 30 had a mean age of 22.36 years, 85% being between 18 and 30 years; in the intermediate group, 30 to 60 years, mean age was 48.40 with 65% between 45 and 60; in the over 60 group, mean age was 68.67 with 70% between 61 and 70 years of age.
