Background: Perineal tear is common during vaginal delivery varied from minor superficial mucosal lacerations to major tears involving the musculature of the perineum. Striaegravidarum (SG) are stretch marks occurred during pregnancy that may be an indicator of poor skin elasticity. The most common injury during vaginal birth is a perinealtear. Aim: The study aimed to assess the association between perineal tear during childbirth and striaegravidarum score. Research design: A crosssectional descriptive research design was used. Setting: The study was conducted in the Obstetrics and Gynecology departments at Beni-Suef University Hospital and Helwan General Hospital, Helwan. Sample: A purposive sample included 300 pregnant women admitted for vaginal delivery was selected. Tools: Three tools were used as the following: Tool 1:A structured interview questionnaire, Tool 2: Initial assessment sheet and Tool 3: Atwal numerical scoring system. Results: In the current study more than half of the studied pregnant women developed perineal tear, second degree perineal tears had the highest percentage of perineal tears followed by third, first and fourth degree perineal tears. The mean length of perineal tear was 5.21±2.36. More than two third of the studied women with perineal tear had single tear and less than one third of them had two perineal tear. There was strong relation was observed between perineal tear during labor and striaegravidarum score. Conclusion: There was significantly association between perineal tear during vaginal delivery and striaegravidarum score. Recommendation: All categories of health professionals can utilize the striaegravidarum score as a simple and noninvasive technique to better classify women at risk for perineal tear
