Tonsillectomy for the treatment of tonsillitis-induced immunoglobulin A nephropathy

Tubular occlusion from red blood cell casts secondary to immunoglobulin A nephropathy (IgAN) is a rare, serious complication of tonsillitis that can cause acute renal failure, also referred to as acute kidney injury. IgAN is the most common primary glomerulonephritis with up to 20% of cases resulting in renal failure worldwide. Tonsillectomy is an effective treatment option for patients suffering from IgAN secondary to recurrent acute tonsillitis. Tonsillectomy alone or in combination with additional medical modalities improves renal function and can have a positive effect on long-term renal survival.
