The correct option is B acute renal failure
Glomerular filtration rate (GFR) is the amount of filtrate formed by both the kidneys per given time. GFR in a healthy individual is approximately 125 mL/min. Rapid fall in GFR may indicate acute renal failure.
Acute renal failure is the rapid or sudden stopping of kidney functioning. The damage is temporary and if the individual recovers from the disease, then the kidneys may start functioning normally.
Another type of renal failure is chronic renal failure. In chronic renal failure glomerular filtration rate decrease is gradual. This type of kidney damage is permanent and cannot be recovered.
Renal stones or kidney stones are insoluble deposits of salt crystals within the kidney.
Hematuria is the presence of blood in a person's urine.
