comparative study of laparoscopic and histerosalpingographic findings in 291 infertile couples

incidence of infertility is 15-20%. tubal and peritontal factors are responsible for 30-40% of infertility cases. in evaluation of infertile women, hysterosalpingography (hsg) is the first test in evaluating of fallopian tubes and laparoscopy is the gold standard test for diagnosing tubal problems and pelvic adhesions. in this study we evaluated 291 infertile couples. study is prospective, descriptive and cross sectional. after ruling out male, ovulatory and cervical factors, hsg and laparoscopy was done for all women. in response to pathologic process, right or left tube will be damaged by the same rate (p<0.05). in evaluating of tubes, similarty of findings in hsg and laparoscopy was 50%. sensitivity and specificity of hsg in diagnosing of patency of tubes was 82% and 81%, respectively, but sensitivity of it in diagnosing of peritubal adhesions is low (31%), but specificity is good (88%). after dividing the patients into groups with and without past history of pelvic surgery, we find that similarly of findings in hsg and laparoscopy in patients with positive history is lower than those with negative history. so, diagnostic accuracy of hsg in patients with past history of pelvic surgery is low (p<0.05).
