Doctor Che-Yi Chou specializes in: 1) Chronic Renal Prevention (20 cases a month), 2) Hemodialysis, peritoneal dialysis (5 cases a month), 3) Integrated care (5 cases a month). Through chronic renal disease preventive methods, we test the family members of our patients so that concealed renal problems can be treated at the earliest time possible. Normally speaking, when a chronic disease develops into an end-stage disease, the changes are irreversible. Thus, we should actively undergo treatment before renal diseases turn to end-stage one. The key lies in dialysis as it delays the worsening and progress of chronic renal disease.
