[Study of 104 patients with renal polycystic disease (author's transl)].

Hereditary factors were observed in 43% of patients. Hypertension was observed in 45% of cases and was not correlated with the degree of renal insufficiency. Serum creatinine was significantly correlated with calcemia and uricemia. Identical correlations were observed in a population of patients whose renal insufficiency was not related to renal polycystic disease. The study provides evidence that, in polycystic kidneys: 1) Hypertension is not related to the degree of renal failure. 2) Hypocalcemia and hyperuricemia are not specific factors of the disease.
