Abstract:
A 15-day- old male infant presented with features suggestive of congenital adrenal hyperplasia (CAH). But on detailed investigation, he had normal 17-OH Progesterone and high aldosterone levels. Infant also had right sided hydronephrosis and associated urinary tract infection. Hence, a diagnosis of secondary pseudohypoaldosteronism was made. There was good response to sodium chloride supplementation and he was thriving well on follow up. While evaluating any infant with suspected CAH, one should consider secondary pseudohypoaldosteronism, especially when risk factors like urinary tract obstruction or UTI coexists.

Renal Tubule and Collecting Duct
Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
