  • Title: [Urinary electrolyte excretion in autosomal dominant polycystic kidney].
    Author: Todorov V, Iordanova P, Penkova S.
    Journal: Vutr Boles; 1991; 30(1):61-4. PubMed ID: 1771865.
    Abstract:
    In 33 patients with autosomal dominant renal polycystosis the urine excretion of the electrolytes sodium and potassium was examined and analyzed in relation to the renal function and the arterial pressure. The clearances, the urine ratio and the excreted fractions of both electrolytes were calculated. It was established that by normal renal function and without arterial hypertension there were no significant differences in the parameters studied between the patients and the healthy controls. In the patients with arterial hypertension and preserved renal function the sodium clearance and urine excretion were lower, but the differences with the normotensive patients were not statistically significant. In the patients with chronic renal failure (when diuretic was applied) higher mean values of the excreted fractions of sodium and potassium were established. The results support the thesis that hypertension in renal polycystosis is of volumetric character.
