概括
子宫角 (UCA) 显示出预测自发早产 (sPTB) 的潜力,特别是在34周之前. 然而,子宫长度 (CL) 仍然是37周前sPTB的更有效预测指标.
科学领域:
- 产科和妇科 产科和妇科
- 医疗成像医学成像
- 围产儿医学 围产儿医学
背景情况:
- 宫长度 (CL) 在泰国预测自发早产 (sPTB) 的表现有限,因为宫短的流行率很低.
- 宫角 (UCA) 被探索为sPTB的替代预测因子.
研究的目的:
- 为了评估UCA的诊断性能与CL相比,用于预测sPTB.
- 评估UCA,CL和宫结合的联合诊断性能,以预测sPTB.
主要方法:
- 在怀孕16-24周之间对单子妊娠的前性队列研究.
- 通过阴道的超声波用于测量UCA和CL.
- 主要结局:UCA的诊断性能及其与其他sPTB参数的整合在37周和34周之前.
主要成果:
- 确定了85° (在37周之前) 和95° (在34周之前) 的UCA切线.
- 低于30mm的CL表现出34周前sPTB的更好预测 (AUC0.71),而不是95°以上的UCA (AUC0.66).
- 将UCA与CL或宫结合并没有改善单独CL的预测.
结论:
- 更广泛的UCA与增加的sPTB风险有关.
- 单独UCA的诊断性能要低于CL或宫结为sPTB预测.
- 在37周之前的sPTB中,CL仍然比UCA更有效的预测器.

Uterus and Cervix
4.0K
The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

Uterine Tubes
1.9K
The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...
