Hornet stings are medically important stings which can cause allergic manifestations and, in severe cases, may lead to the unusual complication of acute renal failure (ARF) and other systemic complications. ARF results from toxic or ischaemic acute tubular necrosis in a setting of haemolysis or rhabdomyolysis or both and acute allergic interstitial nephritis. Venom from hornet stings can also contribute to myocardial injury or liver impairment. Here, we report three cases of hornet stings leading to ARF. Case #1 and Case #3 recovered their renal function and body physiology after a 38-day and 15-day stay in the hospital, respectively, whereas Case #2 died. They were meticulously supported by haemodialysis along with the combination of various drug regimens.
