IgA nephropathy is a very common clinical kidney disease that often attacks or worsens after tonsillitis or gastrointestinal tract infections. However, inflammation of the tonsils is more closely related to this disease. IgA nephropathy often manifests itself in the form of hematuria, or worsening of urinary routine (e.g., red blood cells, urine protein, tubular pattern) after tonsillar inflammation. Therefore, the relationship between tonsils and IgA nephropathy has always been of great concern. In a retrospective study conducted over 15 years, Professor Xie Yansheng, a scholar at the General Hospital of the Chinese People’s Liberation Army, found that tonsillectomy has a beneficial effect on the long-term survival of kidneys in patients with IgA nephropathy. It is evident that tonsil removal is greatly beneficial for bed remission and prognosis of this disease. Patients with lgA nephropathy who have inflammation of the tonsils are more suitable for tonsil removal. Tonsil removal is more effective in patients with hematuric lgA nephropathy, especially in patients with hematuria of the naked eye after tonsillar inflammation. Most scholars consider hematuria or/and worsening proteinuria after tonsillar inflammation with less than moderate renal impairment (or no renal impairment) as the main indications for tonsil removal.
