Background: Infertility is a common gynaecological problem presently encountered in Indian population whose incidence is rising year by year. To assess tubal patency we can use laparoscopy or HSG (Hysterosalpingography) or both. As laparoscopy is considered as gold standard, still HSG should be the first line investigation before undergoing laparoscopy for intrauterine and intratubal pathology.
Aims: The purpose of this study is to find out sensitivity, specificity, positive predictive value and negative predictive value of HSG. To compare findings of HSG and laparoscopy during work up of infertility couples having tubal factors of infertility.
Materials and Methods: After taking consent from the women, hysterosalpingography was done followed by laparoscopy after 3 months. Results of both investigations were compared.
Results: The sensitivity of HSG is 93.3%, specificity is 91.1%, positive predictive value is 77.7% and negative predictive value is 97.6%.
Conclusion: HSG is a very safe, non invasive and cost effective investigation which can be used as a first line test for the diagnosis of tubal patency, especially in rural set up.
