Introduction: The contribution of anatomist and pathologist into the knowledge of the developmental and maturational changes in the human fetal ureter has been significant and play an essential vital role in the development of features. Ureter The ureters in neonates and infants can be anatomically and functionally so severely compromised as to warrant the various congenital terms That__ampersandsignrsquo;s why Microsectional study of the ureter has been a dynamic stair that can contribute to understanding congenital diseases such as agenesis, hypoplasia and dysplasia etc. Aim: My study has brought to light numerous insight into the fine structure of the ureter, with specific embryological highlights with cytologic and physiologic considerations. Materials and Methods: The study was conducted in the Department of Anatomy, JNUIMSRC, Jaipur. Thirty aborted human fetuses between 8- 38 weeks of gestational age with no obvious congenital anomalies were obtained from the Department of Obstetrics and Gynaecology after taking consent of parents following approval from the Institutional Ethical Committee Result: Before 12 weeks there is only mesenchymal tissue appear after that mature histological appearance increase with gestational age in the craniocaudal direction. Conclusion: We are now able to better explain several microstructure-function relationships of the ureter in health and disease.
