: Stress urinary incontinence (SUI) is frequently underrecognized in late pregnancy, with limited tools for effective risk assessment. This study aimed to evaluate the predictive value of clinical and pelvic floor ultrasound parameters for SUI and construct a validated risk model. : Clinical, obstetric, and pelvic floor ultrasound findings were collected from a total of 521 women in late pregnancy who were enrolled in the study. Based on follow-up results, participants were categorized into SUI and non-SUI groups. Logistic regression analyses were used to identify independent risk factors for SUI, which were incorporated into a nomogram. : Four independent predictors were identified: vaginal delivery history (odds ratio [OR] = 2.320), bladder neck funneling (OR = 2.349), bladder neck descent (OR = 1.891), and pubococcygeus muscle contraction strain rate (OR < 0.001). The nomogram achieved an AUC of 0.817 (95% CI: 0.770-0.863) in the training set and 0.761 (95% CI: 0.677-0.845) in the test set. : The nomogram based on clinical and pelvic floor ultrasound parameters accurately predicts the risk of SUI during late pregnancy, offering a useful tool for early identification and personalized management.
压力性尿失禁（SUI）在妊娠晚期常常未被充分认识，有效的风险评估工具有限。本研究旨在评估临床和盆底超声参数对SUI的预测价值，并构建一个经过验证的风险模型。：从总共521名纳入研究的妊娠晚期女性中收集临床、产科和盆底超声检查结果。根据随访结果，将参与者分为SUI组和非SUI组。采用逻辑回归分析确定SUI的独立危险因素，并将其纳入列线图。：确定了四个独立预测因素：阴道分娩史（比值比[OR]=2.320）、膀胱颈漏斗形成（OR=2.349）、膀胱颈下移（OR=1.891）和耻骨尾骨肌收缩应变率（OR<0.001）。该列线图在训练集中的AUC为0.817（95%CI：0.770-0.863），在测试集中为0.761（95%CI：0.677-0.845）。：基于临床和盆底超声参数的列线图能够准确预测妊娠晚期SUI的风险，为早期识别和个性化管理提供了一个有用的工具。
