[Significance of the H-index in the early diagnosis of uremic polyneuropathy].

In 68 patients suffering from chronic renal insufficiency in the stage of compensated retention (36 male, 32 female, 46.9 +/- 12.1 years, Serum creatinine level 250-1350 mumol/l) and in 28 patients treated by chronic hemodialysis (13 male, 15 female, 39.5 +/- 14.1 years) the H-index from the H-reflex arc latency was calculated in comparison with the motoric nerve line velocity. The H-index was a sensitive electroneurographical parameter and better suited for the early diagnosis of an uremic polyneuropathy than the estimation of the motoric nerve line velocity. In 51 patients suffering from chronic renal insufficiency and in 64% of the dialysis patients a pathological H-index was found.
