[Three cases of oligomeganephronia].
Three cases of bilateral renal hypoplasia with oligomeganephronia are reported. In all three patients urine abnormalities were pointed out by annual urine screening for school-children and they showed mild or moderate deterioration of renal function. One patient had repeated episodes of urinary tract infection, and bilateral vesico-ureteral reflux (grade III) was found by the voiding cystourethrography. Light microscopic findings of renal biopsy specimens were similar in three cases; significant hypertrophy of the glomerulus and tubulus; mild mesangial expansion, and interstitial changes. Further histological examination which was done in one case showed widespread foot process fusion, mesangial interposition and membrane-like structures by electron microscopy, and mesangial IgA deposition by immunofluorescence. Three was no alteration in immuno-staining pattern for basement membrane components, including type VI and V collagens, laminin and fibronectin, in the glomeruli.
