N17: Acute renal failure

N17.1: Acute renal failure with acute cortical necrosis

Acute renal failure with acute cortical necrosis is a serious kidney disorder that's characterized by rapid loss of kidney function, specifically affecting the outer region of the kidney known as the renal cortex. In this condition, the cells in the renal cortex suddenly die or become nonfunctional due to a lack of blood supply. This arises rapidly and may be triggered by severe and sudden blood loss, a significant drop in blood pressure, or a traumatic injury that cuts off blood to the kidneys. Common symptoms include lower back pain, swelling in the legs, and decreased urine output. It might also lead to a buildup of waste products in the body, which could result in nausea, vomiting, and confusion. The progression of the disease can be rapid and unpredictable, often ending in complete kidney failure if not promptly addressed.
