Unusual radiological changes associated with probable Bartter's syndrome.
We report 2 cases that fulfill some of the criteria for the diagnosis of Bartter's syndrome and were associated with marked radiological changes. Both patients demonstrated distortion of the caliceal pattern with medullary cavities and loss of cortical substance in the absence of vesicoureteral reflux. However, the glomerular filtration rate was well preserved. It seems unlikely that known organic renal disease was responsible for these changes and the potassium-losing state. These radiological findings also do not appear to be a consequence of hypokalemia and their pathogenesis remains uncertain.
