title: [Transient pseudohypoaldosteronism secondary to congenital malformation pathology of the urinary tract (valves of the posterior urethra): a report of a case with elements of a physiopathological nature].
abstract: A case of secondary transient pseudohypoaldosteronism (PHA) in a three-month-old infant who had arrived in emergency conditions is reported. Clinically the patient presented dehydration associated with salt loss, metabolic acidosis, severe hyperkalemia, markedly elevated levels both of plasma renin activity and aldosterone concentration. Biochemical and instrumental tests and clinical evolution have given reason to consider it as a case of transient PHA, secondary to an obstructive uropathy (PUV) with urinary infection. Secondary forms of PHA have frequently been documented in young infants with urinary tract infection associated with both obstructive and non obstructive uropathy. After medical or surgical therapy the abnormalities quickly disappear. This reported case suggests that the pediatrician-neonatologist dealing with a young infant with obstructive uropathy should not only consider the surgical treatment but also the medical one, in the light of the associated physiopathological aspects.
