盆底脱垂女性骨盆结构的虚拟现实研究

Virtual reality of the female pelvis in pelvic organ prolapse

目的:在虚拟现实环境下,研究盆底脱垂女性患者骨盆三维结构的特点,分析女性盆底脱垂与骨盆结构的相关性。方法:收集2016年1月~2016年12月就诊于妇产科的盆底脱垂女性患者为研究组,无盆底器官脱垂的妇科患者为对照组,利用64排螺旋CT对患者进行盆部平扫,CT数据导入虚拟现实系统进行三维重建,通过切割、旋转等多种手段进行骨盆主要径线、角度和面积的测量。结果:盆底脱垂组骨盆入口横径平均为(131.55±5.09)mm和中骨盆前后径平均为(129.63±5.20)mm较正常组骨盆入口横径(119.04±5.40)mm和中骨盆前后径(114.63±7.01)mm大,两组比较,差异有统计学意义(P<0.05)。结论:女性骨盆结构与盆底器官脱垂有一定的相关性,是女性盆底器官脱垂发生发展的高危因素之一。

Objective To investigate anatomic features in the pelvic bones between women with and without pelvic organ prolapse using virtual reality system and identify relationship between the pelvis structure and the female pelvic organ prolapse. Method We designed a case-control study of women with and without pelvic organ prolapse,they had undergone 64 row spiral computed tomography（ CT） of the pelvis at our institution between January 2016 and December 2016. The CT imaging data was imported into virtual reality system,and we made the pelvis three-dimensional reconstruction and measured the areal,angle and length of the pelvis by cutting,rotating and other methods in the virtual reality system. Results Women with pelvic organ prolapse had a wider transverse inlet（131. 55 ± 5. 09 mm VS 119. 04 ± 5. 40 mm） and a wider anteroposterior midpelvis（129. 63 ±5. 20 mm VS 114. 63 ± 7. 01 mm） than women without pelvic organ prolapse,the difference between the two groups was statistically significant（ P〈0. 05）. Conclusion We speculate that these features of bony pelvic architecture may predispose the patient to neuromuscular and connective tissue injuries,leading to the development of pelvic organ prolapse,which is one of the risk factors in female pelvic organ prolapse.
