Technological advances in the construction of sonographic devices and increasingly universal access to such tests considerably widens the range of diagnostic application of the sonographic examination. This situation also refers to pelvic organs prolapse. At present, sonographic sets used in everyday obstetrical-gynecological practice allow for insight into the structures forming the female pelvic floor, and the obtained images constitute a valuable addition to the physical examination. Positioning the sonographic transducer on a the perineum enables to visualize the three compartments of the female pelvis minor. After freezing the image, it is possible to assess the position of anatomical structures in relation to bones and designated surfaces, establish mutual distances and measure appropriate angles. Most information can be obtained in this manner within the range of the frontal compartment, whose damage is often linked with urinary incontinence. The examination standards developed so far, including the analysis of the quantitative parameters, greatly minimize the potential subjectivity of the assessment of the existing disorders. Apart from its low costs, the main value of the sonographic examination of the pelvic floor is the possibility to dynamically assess the changes in statics which take place during functional testing. Not only does it have a cognitive significance, but also it allows to adjust the scope of the surgical correction to the existing damages. Thus, indirectly it can contribute to the reduction of a number of subsequent remedial surgeries. Three-dimensional sonography allows to thoroughly examine the construction and functioning of the anal levators and to detect their possible damage. It is the trauma to these muscles--occurring, among others, during childbirth--that is one of the major causes of pelvic organs descent and prolapse in women. Sonographic examination also enables to visualize the artificial material, the use of which is increasingly frequent in the surgical treatment of pelvic organs prolapse. The remedial kits currently in use are not visible in classic X-ray examinations and CT however, they can be easily visualized by means of a sonographic test. This way it is possible to locate the positioned tapes or meshes and to establish their orientation towards the urethra, the bladder and the anus. It is also possible to observe the complications (e.g. hematomas) following the surgical procedures via the transvaginal access. Transperineal sonography is a relatively inexpensive method that may be performed in almost every ultrasonographic laboratory Its value, approaching the MRI diagnostic value in the assessment of the pelvic floor defects and its low cost, place ultrasonography on the first place among the methods of imaging the pelvic and uro-genital diaphragm. The results of diagnostics of pelvic organs prolapse obtained by placing the sonographic head on the patient's perineum may also help in establishing the changes of the support apparatus for the uterus and the vagina, bladder urethra and perineum during functional testing and, thus, to verify the clinically established degree of the prolapse. It seems, also, that this method may be used during peri-urethral injections of specific substances and post-application follow-up, an increasingly frequently employed method of urinary incontinence treatment.
超声设备构造方面的技术进步以及此类检查越来越普及,极大地拓宽了超声检查的诊断应用范围。这种情况也适用于盆腔器官脱垂。目前,日常妇产科实践中使用的超声设备能够深入观察构成女性盆底的结构,所获得的图像是体格检查的宝贵补充。将超声探头置于会阴部位,能够可视化女性小骨盆的三个腔室。冻结图像后,可以评估解剖结构相对于骨骼和指定表面的位置,确定相互距离并测量合适的角度。在前部腔室范围内,通过这种方式能够获取最多信息,而该腔室受损常与尿失禁有关。目前制定的检查标准,包括定量参数分析,极大地减少了对现有病症评估的潜在主观性。除成本低廉外,盆底超声检查的主要价值在于能够动态评估功能测试过程中静态状态下发生的变化。它不仅具有认知意义,还能根据现有损伤调整手术矫正范围。因此,它能间接有助于减少后续补救手术的数量。三维超声检查能够全面检查肛提肌的结构和功能,并检测其可能的损伤。正是这些肌肉(尤其是在分娩过程中)受到的创伤,是女性盆腔器官脱垂和下移的主要原因之一。超声检查还能够可视化人工材料,这种材料在盆腔器官脱垂的手术治疗中使用越来越频繁。目前使用的补救套件在传统X射线检查和CT中不可见,然而,通过超声检查可以很容易地看到它们。通过这种方式,可以定位放置的吊带或网片,并确定它们相对于尿道、膀胱和肛门的方向。还可以通过经阴道途径观察手术后的并发症(如血肿)。经会阴超声检查是一种相对便宜的方法,几乎可以在每个超声实验室进行。其在评估盆底缺陷方面的价值接近MRI诊断价值,且成本低廉,使其在盆腔和泌尿生殖膈成像方法中位居首位。将超声探头置于患者会阴部位所获得的盆腔器官脱垂诊断结果,也有助于确定功能测试期间子宫、阴道、膀胱尿道和会阴支撑装置的变化,从而验证临床上确定的脱垂程度。此外,这种方法似乎还可用于尿道周围特定物质注射期间及注射后随访,这是一种越来越常用的尿失禁治疗方法。
