[Hypernatraemia, increased protein intake and progression of renal insufficiency in a patient with polycystic renal degeneration].

The authors submit the case of a patient with polycystic degeneration of the kidneys where after haemorrhage from the anterior cerebral artery hypernatraemia developed and concurrently significant acceleration in the progression of renal insufficiency to failure developed. Hypernatraemia was caused by non-natrium osmotic diuresis conditioned by increased urea excretion. In chronological association with increased dietary protein intake renal insufficiency was hastened.
