OBJECTIVE: To review the ability of imaging techniques to predict incomplete healing of uterine cesarean scars before the next pregnancy. STUDY DESIGN: A systematic literature review searched for studies on women who underwent previous low-transverse cesarean, evaluated by hysterography, sonohysterography (SHG), or transvaginal ultrasound (TVU). The median prevalence of scar defects was computed with 95% confidence intervals (95% CIs). Odds ratio (OR, 95% CI) identified risk factors of incomplete healing. RESULTS: The analysis included 21 studies. The proportions of suspected scar defects detected by hysterography, SGH, and TVU were 58% (33 to 70), 59% (58 to 85), and 37% (20 to 65), respectively. Two studies found that women with a large uterine scar defect had a higher risk of uterine rupture or uterine scar dehiscence than those with no scar defect or small scar defect (OR: 26.05 [2.36 to 287.61], p <0.001). The only reported risk factor for scar defect was the occurrence of more than one previous cesarean (OR: 2.24 [1.13, 4.45], p = 0.02). CONCLUSION: Hysterography, SGH, and TVU can detect uterine scar defects in ~50% of women with previous cesarean.
