To determine whether sonohysterography (SHG) should be performed with Plexiglas hysterosalpingographic vacuum cups instead of standard catheters.
In a prospective setting, 226 women randomly classified into 2 groups underwent SHG. The method used for cervical cannulation was a two-way catheter in the first group (n = 108) and a Plexiglas hysterosalpingographic vacuum cup in the second one (n = 118). Diagnostic reliability, easy applicability for the physician, discomfort for the patients and cost of the instruments were assessed for both devices.
226/226 (100 %) complete sonohysterographic examinations were performed. As regards uterine cavity distension the same diagnostic reliability was reported for vacuum cups and two-way catheters. The standard catheter obscured the cervical canal because of the dilation of the balloon. Both methods were judged as easy to use, and no statistically significant difference was found as far as the time required for cervical cannulation (p > 0.05). A little more discomfort was recorded by women who underwent sonohysterography with standard balloon catheters but a greater interpersonal variability was noticed in this group (SD 3.65 vs. 1.13 in the vacuum cup group). Vacuum cups were by far the most economical devices (unit cost: 16.70 euro vs. catheter unit cost 46.20 euro).
Vacuum cups allow sonohysterography to be correctly performed. As they are inexpensive, easy to use, better tolerated by the patients and more helpful for visualisation of the lower third of the uterine cavity, vacuum cups should be considered a serious alternative to standard catheters in the performance of SHG.
确定子宫声学造影（SHG）是否应使用有机玻璃子宫输卵管造影真空杯而非标准导管进行。
在一项前瞻性研究中，226名随机分为两组的女性接受了子宫声学造影。第一组（n = 108）采用双向导管进行宫颈插管，第二组（n = 118）采用有机玻璃子宫输卵管造影真空杯。对两种装置的诊断可靠性、医生操作的简易程度、患者的不适感以及器械成本进行了评估。
完成了226/226（100%）例完整的子宫声学造影检查。在子宫腔扩张方面，真空杯和双向导管的诊断可靠性相同。标准导管因球囊扩张而遮挡了宫颈管。两种方法均被认为易于使用，宫颈插管所需时间方面未发现统计学显著差异（p > 0.05）。使用标准球囊导管进行子宫声学造影的女性记录到的不适感略多，但该组人际差异更大（真空杯组标准差为1.13，标准球囊导管组为3.65）。真空杯是最经济的器械（单位成本：16.70欧元，而导管单位成本为46.20欧元）。
真空杯可使子宫声学造影正确进行。由于其价格低廉、易于使用、患者耐受性更好且有助于观察子宫腔下三分之一，在进行子宫声学造影时，真空杯应被视为标准导管的一种可靠替代方案。
