Current status of dialysis therapy in Korea

The number of patients with end-stage renal disease (ESRD) is rising very rapidly as the number of elderly and patients with diabetes increases in Korea. ESRD Registry Committee of the Korean Society of Nephrology (KSN) collected dialysis therapy data in Korea through an online registry program on the KSN website. The status of renal replacement therapy in Korea at the end of 2009 was as follows. First, total number of patients with ESRD was 56,396 (hemodialysis [HD], 37,391; peritoneal dialysis [PD], 7,618; functioning kidney transplant [KT], 11,387). The prevalence of ESRD was 1,113.6 patients per million population (PMP). Proportion of patients undergoing renal replacement therapy was 66.3% with HD, 13.5% with PD, and 20.2% with KT. Second, a total of 8,906 (HD, 6,540; PD, 1,125; KT, 1,241; incidence rate of 175.9 PMP) patients developed ESRD in 2009. Third, the most common primary causes of ESRD were diabetic nephropathy (45.4%), hypertensive nephrosclerosis (18.3%), and chronic glomerulonephritis (11.1%). Fourth, mean urea reduction rate was 67.5% and 73.8% in male and female patients, respectively, undergoing HD. Mean Kt/V was 1.38 in male patients and 1.65 in female patients. Fifth, the overall 5-year survival rate of male patients undergoing dialysis was 65.4% and that of female patients was 67.4%.
