Evaluation of Efficacy of Transvaginal Sonography with Hysteroscopy for Assessment of Tubal Patency in Infertile Women Regarding Diagnostic Laparoscopy

Background: Infertility, as one of the most common gynecological disorders, affects many people worldwide. To choose the clinical treatment, correct assessment of tubal patency can provide an important clue; therefore, it is considered as one of the major steps in workup examinations of infertile women. In this study, we aimed to compare the results of transvaginal ultrasonography (TVS) after hysteroscopy (HSC) with laparoscopy, as a gold standard, for assessing the fallopian tubal patency in infertile women. Materials and Methods: This is a cross-sectional study which included 49 infertile women referred to Shahid Beheshti Hospital affiliated with Isfahan University of Medical Sciences during the years 2015 and 2016. At first, patients who met the inclusion criteria were examined through HSC in by a specialist in gynecology and obstetrics in operating room because laparoscopy was performed after TVS with HSC, but HSC was performed without anesthesia. TVS was performed before and after of HSC to observe fluid in the pouch of Douglas. The findings of TVS with HSC and laparoscopy were compared. Results: There was a strong agreement between TVS after HSC and laparoscopy (kappa coefficient = 0.935, 95% confidence interval [CI]: 0.81, 1.00). The sensitivity of TVS after HSC was 100% (95% CI: 66.37, 100) and specificity was 97.50% (95% CI: 86.84, 99.94) with a positive predictive value of 90% (95% CI: 55.50, 99.75) and negative predictive value of 100% (95% CI: 90.97, 100). Conclusion: TVS after HSC is an accurate diagnostic tool for examination of fallopian tubal patency in infertile women.
