Abstract:
Hyponatremic-hypertensive syndrome (HHS) is an uncommon disorder rarely seen in children. Herein, we report a 19-month-old boy with HHS. He had severe hypertension, polyuria, polydipsia, vomiting, and seizure at presentation. Laboratory findings revealed hyponatremia, hypokalemia, metabolic alkalosis, proteinuria, hypercalciuria, high levels of renin and aldosterone, and renal artery stenosis. All symptoms resolved after nephrectomy. Clinicians should be aware of this syndrome because prompt recognition can be lifesaving.

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...
