Acute tubular necrosis after ischemia is caused by blockage of capillaries, preventing blood from circulating to this organ. The condition occurs mainly in patients with low blood pressure, dehydration and severe infection. This is a serious disease with a high mortality rate if not detected and treated promptly.

Interstitial nephritis is a disorder that affects the area around the nephron, resulting in inflammation of the kidneys. Interstitial nephritis can be acute or chronic, but the prognosis is usually good. However, about one-third of people require dialysis while their kidneys recover, so early diagnosis and treatment of interstitial nephritis is very important.
