Description

Statistical observations were made of 800 cases of urological diseases on the red blood cell counts, and the following results were obtained.<br>1) 42.1 per cent of the cases investigated had red blood cell counts of less than 4, 000, 00031 and 7.0 per cent less than 3, 000, 000. 1.6 per cent showed red blood cells of more than 5, 500, 000.<br>2) Anemia was more frequently found in women than in men and in the age than in younger-persons.<br>3) A marked association of anemia with malignant tumors was found irrespective of the sites of tumors.<br>4) The frequency of anemia was the highest in diseases involving both kidneys, followed by diseases of one kidney, diseases of the lower urinary tract, and the frequency was the lowest in diseases not involving the urinary tract.<br>5) Anemia was mostly hyperchromatic, macrocytic and hyposaturated, and did not show anysignificant relationship with leucocytes picture.<br>6) No relationships were found among anemia, hematuria and albuminuria. A tendency to hypoalbuminemia and hypergammaglobulinemia was found in cases associated with anemia.<br>7) A significant, but not definite correlation was found among red blood cell counts, NPN, RPF, RBF, PSP values at 15 minutes and 2 hours, and the Fishberg concentration test.<br>9) 23.8 per cent of the cases presenting anemia showed increased red blood cell counts after-operations, 72.4 per cent showed unchanged counts, and only 3.8 per cent showed decreased counts.<br>It was made clear that urological diseases of the kidneys are responsible for a considerable percentage of anemia. A review of literature was made on its pathogenesis, and it was emphasized that the problem of anemia due to urological diseases of the kidneys deserves much attention in future urology.
