Resumen

CHAPLE LA HOZ, Manuel et al. Estudio de variables morfofuncionales renales en jóvenes con hipertensión arterial primaria. Rev Cubana Invest Bioméd [online]. 1996, vol.15, n.1. ISSN 0864-0300.

The role of the kidney in the genesis of essential arterial hypertension, has been investigated since more than three decades. The purposes of this article was to assess the behaviour of some renal morphofunctional variables in hypertensive patients. The effective renal plasma flow (ERPF) was studied in 40 normal volunteers and 45 hypertensive patients, by means of the paraamino-hippurate clearance, glomerular filtration rate (GFR) by means of creatinine clearance, lithium plasma clearance LiPC), lithium reabsorption fraction (LiRF), sodium and potassium renal management, as well as the ultrasonographic measurement of anteroposterior, transverse and longitudinal renal diameters, with which the kidneys volume was determined by a computed program. The results showed significant differences in ERPF, the renal diameters and the integrated volume, as well as in the sodium management. These outcomes suggest a hydrosaline retention in the hypertensive patients, and this advocates the hypothesis that they restore the kidney participation in the genesis of arterial hypertension.
