Nephritis is the inflammation of the kidneys, particularly affecting the glomeruli, tubules, or interstitial tissue.

Due to the inflammation and damage to the glomerular filtration barrier, proteins leak into the urine, a condition known as proteinuria.

The loss of plasma proteins (such as albumin) in the urine leads to a decrease in the blood colloidal osmotic pressure, which often results in edema.

Obstruction of both the ureters is typically caused by renal calculi (kidney stones), tumors, or strictures. It is a post-renal condition that leads to hydronephrosis, not nephritis.

Answer: Obstruction of both the ureters.
