Davidson 18. Nephrology and Urology

Nephrology and urology explore systems of filtration, flow, and balance. This chapter examines how the kidneys regulate fluid, electrolytes, and waste, and how disruption reveals itself through systemic illness.In this deep dive, we move through acute kidney injury, chronic kidney disease, electrolyte disturbance, and obstructive uropathy.
