Ss. Mersin et al., URINARY CHLORIDE EXCRETION DISTINGUISHES BETWEEN RENAL AND EXTRARENALMETABOLIC ALKALOSIS, European journal of pediatrics, 154(12), 1995, pp. 979-982
The aetiology of normotensive hypokalaemic metabolic alkalosis is some
times not obtainable from the history. Observations in adults indicate
that the urinary chloride excretion is low in metabolic alkalosis of
extrarenal origin. The chloride/creatinine ratio in random urines was
therefore compared in 283 healthy children and in eight paediatric pat
ients with metabolic alkalosis. The urinary chloride/creatinine ratio
was reduced in four patients with metabolic alkalosis of extrarenal or
igin and within reference values or above in four patients with metabo
lic alkalosis of renal origin.
