Residual renal function and effective rehabilitation in chronic dialysis

Abstract

The results of a 1-7 years follow-up of multiple processed and recorded semiquantitative parameters in 148 cases of chronic uremia on regular dialysis treatment (RDT) are reported. Patients were grouped according to different levels of residual creatinine clearance (CCr) at the beginning of treatment (0-5, 5-15, and 15-21 ml/min). Regardless of a possible return to work and reasonable quality of life, patients on RDT with 0-5 ml/min CCr invariably present a worsening in various subclinical parameters semiquantitatively evaluated (bone biopsies; nerve conduction velocity; glucose A-V, etc.). In patients with 5-15 ml/min CCr better results are found. In patients with residual CCr above 15 ml/min, impairment in several parameters is hardly evident and even after several years of dialysis may still remain minimal. These results seem of importance as far as the effective and not the apparent dialysis rehabilitation is concerned.
