Effects of hemodialytic treatment on uremic polyneuropathy. A clinical and electrophysiological follow-up study.

The involvement of peripheral motor and sensory nerve, at least on a subclinical level, is nearly constant event with chronic renal failure. The study of the motor and sensory propagation velocity indicates that a widespread functional lesion of the axon with a peripheral point of attack and secondary demyelination, may be the basic pathogenetic event of uremic polyneuropathy. Prolonged hemodialytic treatment is substantially unable to influence the evolution of uremic polyneuropathy. The electrophysiological follow-up study of the peripheral nerve does not seem to be an index of adequate dialysis.
