[Disorders of intrarenal hemodynamics in glomerulopathies].
The intrarenal hemodynamics was examined in 101 patients with chronic glomerulonephritis (CGN) and 111 patients with type I diabetes mellitus. Intrarenal hypertension was diagnosed from renal functional reserve (RFR) depletion. In CGN intrarenal hypertension was revealed in all clinical and morphological variants of nephritis: in 40% of patients with a nephrotic variant, in 25% with a latent variant and in 83% of patients with nephritis concurrent with the severe urinary syndrome. In focal segmental glomerulonephritis and fibroplastic nephritis, the depleted RFR was encountered 4 times more frequently than the preserved one. There was a association between RFR and arterial hypertension, albuminemia, blood creatinine. In diabetes mellitus intraglomerular hypertension was diagnosed in 34% of patients without renal damage (those having normal albuminuria), in 79% at the preclinical stage of diabetic nephropathy (in microalbuminuria) and in 93% at its clinical stage. Intrarenal hemodynamic disorders in diabetes mellitus are primary and provoked by hormonal metabolic disorders. The morphological signs of renal hyperperfusion failure develop at the preclinical stage of diabetic nephropathy.
