Over the past 5 years, bilateral tonsillectomy has been performed in 1
04 patients (48 male and 56 female) with IgA nephropathy at the Depart
ment of Otolaryngology of Sendai Red Cross Hospital. We studied the re
lationship 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 ra
tes of proteinuria than those with advanced renal pathology. There was
a tendency for higher remission rates in patients with smaller tonsil
s. There were no significant differences relative to past history of t
onsillitis, age, pus plugs in the lacunae, temporary deterioration of
urinary findings after tonsillectomy, and results of provocation tests
.
