Changes in renal haemodynamics in the nephrotic syndrome.
It has repeatedly been found that haemodynamic changes during hypoproteinaemia in the chronic phase of the nephrotic syndrome are different from those during hypoproteinaemia in the acute phase. In our series of patients, a decrease in the filtration fraction and relative hyperperfusion of the kidneys were associated with the presence of the nephrotic syndrome. No significant changes in renal haemodynamics were observed in patients with chronic glomerulonephritis without the nephrotic syndrome or in a group of healthy volunteers. The question of whether relative hyperperfusion of the kidneys in a repeatedly relapsing nephrotic syndrome can lead to the development of focal segmental glomerulosclerosis needs to be elucidated.
