[Relationship between clinical manifestation and pathology in pediatric renal diseases].

To elevate the clinical diagnosis and pathological compatibility of pediatric kidney diseases. Pathological changes from 101 cases of pediatric renal diseases were studied, covering 13 diseases entities, including glomerulo-nephritis, simple nephrotic syndrome, nephritic nephrotic syndrome etc. The technique of tru-cut biopsy under the guidance of B ultrasonogram was used in renal biopsy. The renal puncture biopsy was 100% satisfactory. Pathological changes involved 12 pathological types. MsPGN were the most commonly seen (39.6%), followed by MPGN and ICPGN (12.87% and 10.89%) respectively. It was found that children with similar clinical manifestation may possess different pathological changes, while the same pathological entity may present multiple clinical manifestation. The results suggest that renal biopsy pathological diagnosis is important in the diagnosis, treatment and prediction of prognosis in pediatric renal disease.
