[Uremic polyneuropathies].

The report is concerned with the results of a study of polyneuropathy in 75 patients with acute and chronic renal insufficiency. The authors described the clinical characteristics of the different forms of neuropathy. In acute renal insufficiency the first signs of polyneuropathy appear during the stage of polyuria and are reversible. In chronic renal insufficiency and hemodialysis treatment of subclinical an sensory forms of neuropathy are mainly seen (2/3 of the patients). It was demonstrated that there was a retardation in the velocity of excitative conductivity through the nerves depending upon the severity of polyneuropathy. A longterm adequate hemodialysis may prevent the further development of polyneuropathy.
