本研究试图了解尿免疫复合物（ＵＩＣ）检测能否反映肾小球所发生的免疫病理改变。结果表明ＵＩＣ主要出现于肾小球病变严重的病人，如毛细血管内增生性肾炎（ＥｎＰＧＮ），膜性肾病（ＭＮ），弥漫增殖性肾炎（ＤＰＧＮ）或免疫复合物（ＩＣ）介导致病的临床类型如急性链球菌感染后肾炎（ＡＰＳＧＮ），狼疮肾炎及部分肾炎性肾病（ＮＮＳ）患儿尿液之中。ＵＩＣ阳性病人肾小球多伴有ＩｇＧ及Ｃ３沉积，分析表明ＩｇＧ类ＵＩＣ检测能提示ＩｇＧ类ＩＣ所致肾病变，长期使用激素治疗的迁延性肾病变不易检出ＵＩＣ。 This study sought to determine whether the urine UIC test can reflect the immunopathological changes that occur in glomeruli. The results show that UIC mainly occurs in patients with severe glomerular lesions, such as EnPGN, MN, proliferative glomerulonephritis (DPGN) or immune complex (IC) The clinical types such as acute streptococcal nephritis (APSGN), lupus nephritis and some nephritis (NNS) in children with urine. UIC-positive patients with glomerular accumulation of IgG and C3, analysis showed that IgG-like UIC test can prompt IgG-induced ICC nephropathy, prolonged steroid-treated patients with persistent renal disease is not easy to detect UIC.
