わが国の慢性透析療法の現状 (1990年末現在)

抄録

Each year The Japanese Society for Dialysis Therapy has run a questionnaire survey on the status of the chronic dialysis patients in Japan. Accumulated data as of December 31, 1990 were as follows. The response rate was 97.6%, and dialysis for such patients was conducted at 2, 101 facilities, up 21.1% from the previous year. Chronic dialysis patients numbered 103, 296 in all, among which 73, 868 were treated in the day and 24, 806 at night. There were 35 patients on home dialysis, 45, 36 on CAPD and 51 IPD treatment. Patients numbered 835.7 per million population and showed straight-line growth. In 1990 new patients beginning treatment were 18, 441 and death occurred in 8, 936 patients. Patients increased by 9, 474 that year, and male patients (59.1) outnumbered female patients (40.8). The mean age was 54.03 years for males and 54.26 for females, reflecting an increasingly higher mean age.
Chronic glomerular nephritis (64.1%) was the basic disease, followed by diabetic nephropathy (14.9%), polycystic kidney (3.3%), nephrosclerosis (2.6%), and pyelonephritis (2.2%). Deaths were due to cardiac insufficiency (30.4%), cerebrovascular disorders (13.9%), infectious diseases (11.6%), malignoma (8.2%), and myocardial infarction (5.6%). Survival rates for one to seven years were 0.833, 0.758, 0.698, 0.649, 0.608, 0.583, and 0.559, respectively. The survival rates for 7 years for basic diseases were as follows: chronic glomerular nephritis 0.655, diabetic nephropathy 0.322, polycystic kidney 0.667, nephrosclerosis 0.308, and pyelonephritis 0.553.
Thus, with increasingly older patients and those suffering from complications refractory to treatment, more sophisticated treatment and greater care are required.
