Background: The Umbilical Cord Coiling Index (UCCI) has been proposed as a potential marker for predicting adverse perinatal outcomes. This review aims to find out the association between UCCI and perinatal outcomes. Methods: A comprehensive search of electronic databases (PubMed, Scopus, and Web of Science) was conducted to identify studies investigating the relationship between UCCI and perinatal outcomes. Studies were comprised if they reported UCCI values and perinatal outcomes. Results: Fifteen studies (n=4500 participants) were included. Hypo coiled cords were associated with preterm delivery (OR 2.5, 95% CI 1.8-3.5), low birth weight (OR 2.2, 95% CI 1.5-3.2), and NICU admission (OR 3.1, 95% CI 2.1-4.5). Hyper coiled cords were associated with fetal distress (OR 2.8, 95% CI 1.9-4.1) and meconium-stained liquor (OR 2.3, 95% CI 1.6-3.3). Conclusion: Abnormal UCCI values are associated with adverse perinatal outcomes. UCCI may be a useful predictor of high-risk pregnancies.
