Relative Erythrocythemia (Polycythemia) and Polycystic Kidney Disease, with Uremia

Abstract

RECENTLY polycythemia or erythrocythemia apparently associated with renal disease of several diverse types, including hydronephrosis,^{1 , 2} hypernephroma^{3 4 5 6 7 8 9} and renal adenoma¹⁰ and fibromyxoma,³ has been noted. To the best of our knowledge only 2 reports are available concerning the association of erythrocythemia and polycystic kidney disease.^{3 , 11} We recently studied a patient with polycystic kidney disease who presented originally as a diagnostic problem exhibiting a high blood urea nitrogen concentration, proteinuria, hypertension and a normal hematocrit. A normal hematocrit in the face of significant uremia was sufficiently unusual to prompt a study of the frequency of this association. It is the purpose of . . .
