BACKGROUND The aim of this study was to assess usefulness of sonosalpingography in determining role of tubal factor in cases of infertility as an initial measure as compared to hysterosalpingography and diagnostic laparoscopy. MATERIALS AND METHODS This was a descriptive study conducted over a period of 9 months. 50 patients with infertility attending the infertility clinic in OPD of Obstetrics and Gynaecology were evaluated clinically with detailed history. All patients were subjected to

... lpingography, hysterosalpingography and laparoscopy and the findings were documented. RESULTS There were 40 cases (80%) with primary infertility and 10 (20%) with secondary infertility. Sonosalpingography has 94.87% sensitivity rate with laparoscopic chromopertubation as reference standard whereas hysterosalpingography has 87.17% sensitivity rate. Laparoscopy has better diagnosis rate than HSG and sonosalpingography in pelvic pathologies. CONCLUSION Sonosalpingography is a simple office noninvasive procedure having slightly better diagnostic value than HSG and somewhat similar to laparoscopy for determining tubal patency. We conclude that all patients with infertility should undergo sonosalpingography as an initial measure to assess tubal patency as part of their primary workup of infertility.
