[Estimation of renal tubular function after uropoline administration in certain disease states]. / Ocena czynnosci cewek nerkowych po podaniu uropoliny w niektórych stanach chorobowych.

ABSTRACT

24 h urinary excretion of beta-microglobulin (beta 2M) and Tamm-Horsfall protein (THP) before and after administration 40 ml of 75% Uropoline were assessed, as a specific markers of proximal and distal tubular dysfunction respectively. 22 patients without renal diseases and hypertension (C), 22 hypertensive patients (HP), 14 patients with renal stone disease (RSD) and 16 patients with pyelonephritis (PN) were examined. Administration of Uropoline did not change beta 2M and THP urinary excretion in C, but increased beta 2M excretion in HP and decreased THP urinary excretion in patients with RSD. It is concluded, that Uropoline shows a noxious effect on the proximal tubule in HP and on the distal tubule in patients with RSD.
