Q: My 36 years old wife has a kidney problem. She had undergone biopsies and report shows it an acute renal problem. The nephrologist had given her steroids for a month. Her creatinine level was reduced from 3.0 to 2.6 mg/dl, this level continued for three months but again after 4 months it decreased to 2.3 mg/dl.Is it chronic renal failure or acute renal failure?

A:Kidney dysfunction lasting for more than three months is chronic kidney disease. Acute kidney injury usually recovers within 3 months, any dysfunction, which has not recovered in 3 months is unlikely to recover and thus called chronic.
