Tubal patency was studied in 53 infertile women by means of colour-coded duplex sonography (CCDS) with transcervical injection of normal saline. In 47 women the patency was studied using a 2.5 MHz transabdominal transducer while in the last six cases, a 5.0 MHz vaginal probe was used. The results were compared with a conventional hysterosalpingogram (HSG) and laparoscopic chromopertubation. When the results of CCDS were compared with those of HSG and laparoscopy, there was a 92.5% agreement, that is, there was patency or occlusion of the Fallopian tubes. In addition, CCDS demonstrated all the soft tissues and their mobility. The colour signals generated by the air bubbles make it possible to demonstrate tubal patency on both sides separately. Vaginal CCDS offers a much better resolution with the advantage of lesser volume of normal saline being utilised. Tubal patency can be demonstrated in the presence of anatomical complications and requires only a small quantity of normal saline. This new tubal patency test is offered, not as a substitute for HSG, laparoscopy, hysteroscopy or salpingoscopy, but as a screening technique in the armamentarium of infertility investigations.
通过经宫颈注射生理盐水，采用彩色编码双功超声检查（CCDS）对53名不孕女性的输卵管通畅情况进行了研究。47名女性使用2.5MHz经腹探头进行通畅情况研究，而在最后6例中，使用了5.0MHz阴道探头。将结果与传统子宫输卵管造影（HSG）和腹腔镜输卵管通液术进行比较。当将CCDS的结果与HSG和腹腔镜检查的结果进行比较时，一致性为92.5%，即输卵管存在通畅或阻塞情况。此外，CCDS能够显示所有软组织及其活动情况。气泡产生的彩色信号使得能够分别显示双侧输卵管的通畅情况。阴道CCDS具有更好的分辨率，优点是使用的生理盐水体积较小。在存在解剖学并发症的情况下也能显示输卵管通畅情况，且仅需少量生理盐水。这种新的输卵管通畅性检查并非作为HSG、腹腔镜检查、宫腔镜检查或输卵管镜检查的替代方法，而是作为不孕不育检查手段中的一种筛查技术。
