MRI visualization of the female pelvis in the plane of the tension-free vaginal tape (TVT) procedure

We evaluated the distances and angles of the major blood vessels from various pelvic structures in the plane of the tension-free vaginal tape (TVT) procedure in 19 pelvic MR imagies. The major blood vessels were the iliofemoral vessels. The mean distance of the left iliofemoral vessels from the midline was 5.7±0.4 cm, and 5.7±0.3 cm for the right vessels. The mean distance of the left sacral tuberosities from the midline was 5.5±0.4 cm, and 5.6±0.3 cm for the right vessels. The angle between the midurethra and the left iliofemoral vessels was 50.6±4.4 cm, and 49.6±4.0 cm for the right. A significant correlation was found between the distance of the right and left iliofemoral vessels from the midline and the distance of right and left sacral tuberosities from the midline (P<0.01, P<0.007). We suggest that palpation of the sacral tuberosities might indicate the location of the iliofemoral blood vessels.Abbreviations - TVT Tension-free vaginal tape - - MRI Magnetic resonance imagingEditorial Comment: The authors evaluated the distances and angles of the major pelvic blood vessels in the plane of the tension-free vaginal tape (TVT) procedure in 19 pelvic MR images. A statistically significant correlation was found between the distance of the iliofemoral vessels from the midline and the distance of the sacral tuberosities from the midline. The authors suggest that palpation of the sacral tuberosities might alert the surgeon to those patients at greater risk for iliofemoral vessel injury during the TVT procedure.The main concern with this study is that the pelvic MR images were obtained in the supine position whereas the TVT is performed in the lithotomy position, which may change the relations of pelvic blood vessels with reference to the urethra. Further studies are needed to evaluate the clinical significance of this interesting observation in reducing vascular injuries during the TVT procedure.     

影响尖锐湿疣复发的危险因素分析及干预对策

目的：分析尖锐湿疣（CA）复发的危险因素,并探讨相应的干预对策.方法：回顾自2006年6月份以来,入我院治疗的尖锐湿疣（CA）患者的资料,对患者的一般情况如性别、年龄、婚姻情况及受教育程度,个人行为如饮酒、吸烟、熬夜情况、野游史、安全套的使用情况、传染性伴侣的情况,患者的皮损发生部位、范围、颜色、数目、感染HPV病毒的亚型、复发的情况,采用卡方检验、单因素非条件Logistic回归分析和多因素非条件 Logistic回归分析,模型筛选采用Stepwise法,评价影响尖锐湿疣复发的危险因素.结果：显示嗜酒（OR=1.769,95% CI：1.420-2.115）、熬夜（OR=6.447,95% CI：1.826-22.769）、皮损发生在肛周（OR=0.863,95% CI：0.709-1.051）、皮损HPV型别为16型（OR=1.539,95% CI：1.042-2.635）、皮损HPV型别为复合型（OR=3.640,95% CI：2.169-6.193）等是尖锐湿疣（CA）复发的主要促进因素.结论：针对尖锐湿疣（CA）复发的危险因素,我们提出了尖锐湿疣（CA）患者应注意禁止饮酒、不熬夜;在肛周,治疗时的物理疗法,深度要达到疣体的底,范围要大于疣体.
