Ten patients with chronic renal failure from different genesis (serum
creatinine levels 150-200 mu mol/l), were evaluated from the aspect of
the effect of the diuretic therapy. The effects of furosemide (FUR) a
nd polythiazide (POL) were assessed after 3-month application. The mea
n values of the estimated parameters before treatment, after 3-month a
dministration of FUR as a monotherapy and after the next 3 months simu
ltaneosly used (FUR + POL), presented a stable increase of the diuresi
s, without statistically significant changes of the global renal funct
ion, and triglyceride disorders. On the contrary, the improvement of c
alciuria through combined using of furosemide and polythiazide is stat
istically and clinically significant.
