We report a case of endolymphatic hydrops preceded by haemodialysis in the contralateral ear of a patient with known Menière's disease, and discuss the possible mechanism. It is suggested that the sudden decrease of plasma osmolality during haemodialysis acts as a reverse glycerol test. The audiometric and electrophysiological recordings pre- and post- dialysis and the induction of the Menière's triad of symptoms during dialysis, were strongly indicative of the presence of endolymphatic hydrops.
