Clinical study of chronic tonsillitis with IgA nephropathy treated by tonsillectomy.

Over the past 5 years, bilateral tonsillectomy has been performed in 104 patients (48 male and 56 female) with IgA nephropathy at the Department of Otolaryngology of Sendai Red Cross Hospital. We studied the relationship between remission rates as shown by urinary findings at one year after tonsillectomy and various clinical factors. Patients with mild or moderate renal pathology had higher postoperative remission rates of proteinuria than those with advanced renal pathology. There was a tendency for higher remission rates in patients with smaller tonsils. There were no significant differences relative to past history of tonsillitis, age, pus plugs in the lacunae, temporary deterioration of urinary findings after tonsillectomy, and results of provocation tests.
