What causes an enlarged kidney and kidney stones?

In brief: Obstruction.

A kidney that is obstructed by a kidney stone can swell in a condition called hydronephrosis.
This can, over time, affect the function of the kidney. Kidney stones can form when solutes in the urine come out of solution. The exact cause in an individual is usually not known, but there is likely a genetic component and known risk factors such as dehydration, high-salt, high-protein diet.
