[The determination of the separate intrarenal hemodynamics and its place in the diagnosis of nephrogenic arterial hypertension].
Differential diagnosis between essential hypertension and secondary arterial hypertension (AH) that developed in the presence of chronic pyelonephritis was made in 12 patients with AH and the urinary syndrome (leukocyturia and bacteriuria). With that purpose in view for revealing functional renal asymmetry, a study was made of the effective renal plasma flow (ERPF) and glomerular filtration rate (GFR) in each kidney separately based on computation of 99Tc-DTPA and 131I-hippuran clearances. Some patients in whom AH was later regarded as essential manifested practically equal values of the ERPF and GFR from both sides, with the real characteristics of the latter ones being little different from the respective populational values calculated by computer bearing in mind the body surface of those patients. The other patients' group showed, along with a decrease of the total ERPF and GFR, a dramatic asymmetry of the intrarenal hemodynamics of both ERPF and GFR, which is fairly characteristic of chronic pyelonephritis. This allows the syndrome of AH to be regarded in those patients as secondary.
