Sonosalpingography

Abstract: Background During the past few years, sonosalpingography has been suggested as the first-line method to study tubal patency. This study was launched in order to study the applicability of this method at our institution. Methods Thirty-two patients suffering from primary or secondary infertility were evaluated for tubal patency with sonosalpingography using a pediatric Foley urinary catheter and a combination of air and saline solution as a contrast medium. The uterine tubes were evaluated separately and the results were compared to the findings at laparoscopy and chromotubation performed independently. Four patients conceived before their scheduled laparoscopy and were excluded from the study. In addition, the patency of three Fallopian tubes could not be adequately evaluated, leaving altogether 53 uterine tubes that were evaluated by both methods. Results The findings of both methods agreed in 47 out of 53 tubes (concordance, 88.7%). The sensitivity of sonosalpingography in diagnosing tubal patency was 90.2% and the specificity 83.3%. The positive predictive value for tubal patency by sonosalpingography was 94.9% and the negative predictive value 71.4%. Adverse events of sonosalpingography included moderate to severe abdominal pain in three patients, one vasovagal reaction, and one case of shoulder pain. No infectious complications were recorded. Conclusions The results confirm that sonosalpingography utilizing air and saline as a contrast medium is a reliable, simple and well-tolerated method to assess tubal patency in an outpatient setting. In addition, the procedure can be performed without prophylactic antibiotics using a regular pediatric Foley urinary catheter instead of an expensive hysterosalpingography catheter.

Abstract: The diagnostic accuracy of sonohysterography combined with sonosalpingography or sonohysterosalpingography was evaluated in 100 infertility patients who also underwent endoscopic (hysteroscopy with or without laparoscopy) procedures. In patients with normal endometrial biopsy results, single endometrial layer thickness ranged from 3 to 5 mm and varied up to 2 mm in some areas. Diagnostic accuracy was 98% for submucosal fibroids, 96% for polyps, and 81% for synechiae. Missed lesions, were less than 2 mm in diameter. Tubal patency was successfully assessed in 79% of women with saline solution and in 92% of those who received contrast agent. This study demonstrates the efficacy of the combined use of SHG and SSG in infertility patients with uterine or tubal factor disorders.

Abstract: Proximal, distal, and peritubal damage can be caused by a number of pathologic processes such as inflammation, endometriosis, and surgical trauma. The diagnosis of tubal occlusion relies primarily on hysterosalpingography, hysteroscopy, and laparoscopy. A number of innovative diagnostic procedures such as sonosalpingography, falloposcopy, and selective salpingography improved our ability to accurately diagnose tubal pathology. The long-standing surgical corrective approach to treat tubal occlusion has been replaced by noninvasive methods in selected patients with endoluminal damage. The development of noninvasive transcervical catheter methods to recanalize proximally obstructed fallopian tubes also allows access to the fallopian tubes for deposition of gametes and embryos and improves the diagnosis and treatment of tubal pregnancies. Transcervical tubal cannulation reduces the risks, costs, and morbidity of surgical procedures. The diverse applications of the transcervical tubal approach may also replace surgical invasive procedures in assisted reproductive procedures. Although radical changes have occurred in the treatment of proximal tubal occlusion, the repair of distal and peritubal damage frequently yields disappointing results, and will probably remain the challenge of the 1990s.
