Abstract
Pseudohypoaldosteronism is a syndrome characterized by unrepsonsiveness to aldosterone of renal tubuli and is manifested by hyperkalemia, hyponatremia and metabolic acidosis. Most of the secondary forms of pseudohypoaldosteronism have been reported to be associated with pyelonephritis secondary to obstructive uropathy or vesicoureteral reflux. However, this hyponathremia/hyperkalemia condition may also be seen in infants with acute pyelonephritis, even in the absence of uropathy. Herein we report 38-day-old female patient with meningocele and pseudohypoaldosteronism secondary to acute pyelonephritis who had no urinary tract anomalies
Keywords: Acute pyelonephritis, infant, pseudohypoaldosteronism
