Objective: To evaluate the relationship between umbilical cord coiling index with perinatal out come. Method: Total of 500 pregnant ladies with singleton term gestation were included in the study done over a period of one year. UCI was caliculated and perinatal outcome was analysed. Results: Out of the 500 subjects, 390 were normocoiled, 58 were hypocoiled, 52 were hypercoiled. 89% of hypo coiled cord was associated MSAF. IUGR was observed in 80% of hypercoiled cords. NICU admission was high with hypocoiled cords. Conclusion: Abnormal umbilical coiling index either hyper or hypo coiled is associated with adverse perinatal outcome.
