Comparative Evaluation of Hysterosalpingo Contrast Sonography with Laparoscopy for Tubal Factor in Infertility

Tubal pathology accounts for 25-35% of cases of infertility. Rubin`s test, hysterosalpingography, saline infusion sonography, hysterosalpingo contrast sonography and laparoscopic chromotubation are the tests done for tubal evaluation. Laparoscopic chromotubation is the gold standard test and the results of all other tests are compared with laparoscopic findings for its specificity and sensitivity. Hysterosalpingo contrast sonography (HyCoSy) is done by injecting an echo contrast drug containing microbubbles, into the uterine cavity and studying the tubal patency ultrasonographically. The study aimed at establishing the validity of HyCoSy as a reliable method of tubal patency and to compare its efficacy with larascopic chromotubation. The present study was done in an infertility centre in south India. Eighty four women underwent HyCoSy with Sono Vue by 2D B mode trans abdominal sonography. The results were compared with the results of laparoscopic chromotubation on the same women. In identifying unilateral or bilateral tubal patency or tubal block yCoSy results were with 87.5% sensitivity; 92.31% specificity; 87.5% positive predictive value and 92.31 negative predictive value and the diagnostic value is 90.48%. The study concludes that HyCoSy is a reliable method for diagnosing tubal patency.
