To evaluate the distribution pattern of renal diseases based on needle biopsy, we analyzed 817 cases of renal biopsies at the Department of Pediatirics from Jul. 1978 to Jun. 1993. We excluded 17 cases of insufficient material and repeated biopsy
in 70
patients. In 717 cases, the wex ratio (M : F) was 2.3:1. The average age was 8.2 years in males and 8.5 years in females. Glomerular diseases wee 98.5% of the total. The major glomerular deiseases, in descending order of freqeucy, were; benign
recurrent
hematuria including thin glomerular basement membrane disease (BRH: 31.7%), minmal change nephrotic syndrome (MCNS: 25.0%), acute poststreptococcal glomerulonephritis IAPSGN: 10.6%), Henoch-Sch?lein purpura nephritis (HSPN: 9.9%), IgA nephropathy
(IgAN:
7.5%) mesangioproliferative glomerulonephritis (MsPGN: 3.8%), membranous nephropathy (MN: 3.1%). HBs antigenemia was found in 36 cases of which MN was the most frequent (68.2%0. The causes of nephrotic syndrome were MCNS (63.7%), APSGN (7.5%), MN
(6.8%), HSPN (6.8%), FSGS (3.9). The causes of hematuria were BRH (55.2%), APSGN (13.4%), HSPN (12.7%), IgAN (11.7%). A repeated biopsy was obtained from 70 patients because of evaluating the treamtent response. Two cases of MCNS were confirme by
second
biopsy to be FSGS. After the renal biopsy, complications were developed in 6 cases (0.7%). Blood transfusion was done in 5 cases, arteriovenous fistula developed in one case.
