摘要
The pathogenesis of active renal stone disease (ARSD) is still not fully elucidated. In the present study the role of atrial natriuretic peptide (ANP) and argininevasopressin (AVP) as potential pathogenetic factors in ARSD were examined. Thirty patients with ARSD and 21 healthy subjects (HS) were examined both under bed rest (BR) and head-out water immersion (WI) conditions. Serum concentrations of electrolytes (Na, Ca, Mg), ANP and AVP were assessed before (0'), and after 60 and 120 minutes of BR or WI, respectively. Urinary excretions of Na, Ca, Mg, and oxalates were also estimated during BR and WI. Patients with ARSD showed higher basal plasma levels of ANP and a greater response of ANP secretion, but a lower suppression of plasma AVP to WI induced hypervolaemia as compared with the controls. In addition, in patients with ARSD the physiological relationship between plasma AVP concentration and urinary excretion of Ca and Mg (positive correlation), between plasma ANP level and urinary excretion of Ca and Mg (negative correlation), and between plasma ANP and AVP concentration (negative correlation), respectively, were absent. In addition, patients with ARSD showed a positive correlation between plasma ANP and urinary oxalate excretion. From the results obtained in this study we conclude that both AVP and ANP may be involved in the pathogenesis of ARSD.
