Background: The Umbilical Coiling Index (UCI) is a measurement used in obstetrics to assess the coiling or twisting of the umbilical cord in a fetus during pregnancy. The present study was conducted to assess relation of umbilical coiling index & the perinatal outcome. Materials & Methods: 56 healthy women with term gestation were enrolled. By dividing the total number of coils by the total cord length in centimeters, the UCI was calculated. Perinatal factors were recorded. Results: Meconium staining was present in all 6 cases of hypocoiling, 23 cases of normocoiling and 10 cases of hypercoiling. The difference was significant (P< 0.05).Apgar score at 1 minute <4 was seen in 6, 12 and 1 and >4 in 9, 28 and 9 in hypocoiling, normocoiling and hypercoiling cases respectively. Apgar score at 5 minutes <7 was seen in 6, 30 and 6 and >7 in 0, 10 and 4 cases of hypocoiling, normocoiling and hypercoiling respectively. IUGR was seen in 1, 19 and 7 and NICU admission in 2, 18 and 1 hypocoiling, normocoiling and hypercoiling cases respectively. The difference was significant (P< 0.05). Conclusion: UCI [90th percentile of the umbilical cord (hypercoiling) is associated with IUGR, and UCI 10th percentile of the cord (hypocoiling) is associated with low Apgar scores at 1 and 5 minutes, respectively, and meconium staining.
