Developmental Changes in Histology Of Human Fetal Kidney

The study was made on histology of human fetal kidney. The present study was carried out in the department of Anatomy, Government Medical College & Hospital, Chandigarh. The material for the study consisted of 30 spontaneously aborted human fetal specimens from 12 th to 30 th weeks of gestational ages. The kidneys were taken from fetal specimens for histological study. Slides were prepared .Hematoxyllin and eosin was done .It was observed nephrogenic zone decreased as gestation advanced, PCT and DCT were more prominent after 18 th week of gestation. Cortico medullary differentiation was seen in later gestational period. It was thought that an understanding of histology of fetal kidneys would elucidate pathogenesis of abnormal kidney.
