This study aimed to explore the feasibility of transperineal virtual touch tissue quantification (VTQ) for predicting the outcome of labor induction. A total of 80 nulliparous pregnant women were included. Before labor induction, cervical length was measured by B-mode sonography, cervical stiffness was measured by VTQ, and Bishop score was assessed by vaginal examination. Subsequently, labor was induced using standard oxytocin infusion in all patients. Delivery within 24 hours after labor induction was classified as spontaneous delivery; otherwise, cesarean delivery was performed. Out of 80 participants, 48 (60%) delivered vaginally and 32 (40%) underwent cesarean delivery. The cervical length was significantly longer and the shear wave velocity (SWV) was greater in the cesarean delivery group than in the vaginal delivery group (p = 0.004 and p < 0.000, respectively). Logistic regression analysis indicated that only the mean SWV had independent predictive value for the outcome of labor induction (p = 0.011). The best diagnostic cut-off point of the mean SWV was 1.23 m/s, with a sensitivity of 93.8% and a specificity of 89.6%. Transperineal VTQ technique could predict the outcome of labor induction using oxytocin.

本研究旨在探讨经会阴虚拟接触组织量化（VTQ）预测引产结果的可行性。共包括 80 名未生育的孕妇。引产前采用B超测量宫颈长度，VTQ测量宫颈僵硬程度，阴道检查评估Bishop评分。随后，在所有患者中使用标准催产素输注引产。引产后24小时内分娩为自然分娩；否则，进行剖宫产。在 80 名参与者中，48 名 (60%) 阴道分娩，32 名 (40%) 接受剖宫产。与阴道分娩组相比，剖宫产组的宫颈长度明显更长，剪切波速度（SWV）更大。p  = 0.004 和p < 0.000，分别）。Logistic 回归分析表明，只有平均 SWV 对引产结果具有独立预测值 ( p  = 0.011)。平均 SWV 的最佳诊断截止点为 1.23 m/s，敏感性为 93.8%，特异性为 89.6%。经会阴 VTQ 技术可以预测使用催产素引产的结果。
