Hemodialysis patients who have residual kidney function will undergo two 4-week study (twice weekly versus thrice weekly hemodialysis). Blood, urine, and dialysate samples will be collected at the end of each study period to determine adequacy of treatment and to assess uremic solute levels. Participants will complete quality of life questionnaires and cognitive paper tests. Food records and medications may be monitored.
The study will determine the efficacy of twice weekly hemodialysis in patients with residual kidney function.
