Nephrocalcinosis in Bartter's syndrome. Demonstration by ultrasonography.
Nephrocalcinosis in Bartter's syndrome has been recognized since 1962, but has not previously been shown in an infant with the syndrome. Ultrasonography shows striking echogenicity of the renal pyramids which appears to be a specific finding in medullary nephrocalcinosis. We suspect nephrocalcinosis will be found in many infants with Bartter's syndrome if ultrasonography is used to examine their kidneys.
