概括
使用常规超声检测结果的机器学习模型可以预测水缩症儿童的脏阻塞风险,有助于安全地避免不必要的尿液瘤学. 这种方法改善了儿科脏阻塞的诊断标准.
科学领域:
- 儿科泌尿外科 儿科泌尿外科
- 医疗成像医学成像
- 医疗保健中的机器学习
背景情况:
- 利尿性瘤学是评估儿科水缩症中脏阻塞的标准工具.
- 常规超声波 (US) 发现经常被使用,但预测阻塞风险可能是具有挑战性的.
- 需要改进的标准来识别那些可以安全地避免尿液改造的儿童.
研究的目的:
- 开发一种机器学习模型,使用美国常规研究结果来预测阻塞风险.
- 为了确定推迟隔离水解的儿科患者的尿道术的安全标准.
- 为了比较模型的表现与胎儿泌尿学会 (SFU) 的表现.
主要方法:
- 对304名患有隔离水性的患者进行了回顾性分析,这些患者接受了脏US和利尿剂瘤学.
- 抽象的数据包括患者人口统计和常规的美国发现 (侧向,长,前后直径,SFU等级).
- 一个随机森林模型,称为"人工智能对Renogram阻塞的评估" (AERO),被训练来分类阻塞风险.
主要成果:
- 该AERO模型实现了0.84的接收器操作特征曲线 (AUROC) 下的二进制面积,超过了SFU等级.
- 外部验证表明二进制AUROC为0.76,年龄,前后直径和SFU等级是关键预测特征.
- 在30%的概率值下,AERO可以使每1000名患者中有66名患者能够安全地避免造术,与常规的SFU等级≥3标准相比.
结论:
- 常规的超声波检测结果,当与机器学习相结合时,可以增强在患有孤立水缩症的儿童中安全推迟尿液造术的标准.
- 开发的AERO模型显示了改善尿瘤学患者选择的前景.
- 在广泛临床实施之前,需要进一步优化和验证.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Imaging Studies I: Kidney, Ureter, and Bladder Studies

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
