Abstract:
A 2-month-old girl was diagnosed with a febrile urinary tract infection. Subsequent studies revealed a right renal duplication anomaly with a poorly functioning upper pole moiety subtended by an intravesical ureterocele. The patient was also found to have hyperkalemia, hyponatremia, and elevated serum aldosterone. After antibiotic therapy, the urinary tract infection resolved, although the electrolyte and hormonal abnormalities persisted. At 4 months of age, a right upper pole heminephrectomy was performed. The patient's electrolyte and hormonal levels normalized. This case represents an unusual case of pseudohypoaldosteronism presenting with urinary tract infection and obstructed upper pole moiety that resolved after surgical intervention.

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...
Disorders of the Urinary System
Urinary tract infections (UTIs) are one of the most common urinary system disorders. They are caused by bacteria that enter the urethra and can spread to the bladder resulting in cystitis. Pyelonephritis is the result of a UTI that has ascended to the level of the...
