Purpose: This study was done to compare sonohysterography and correlate by hysterosalpingogram (HSG) for evaluation of utero tubal factor in female infertility.
Methods: Thirty women with primary or secondary infertility attending the outpatient department of the Department of Obstetrics & Gynaecology, Mahatma Gandhi Memorial Hospital, Kalamboli, from May 2010 to May 2011 underwent a sonosalpingography (SSG) on day 7 of the menstrual cycle and an HSG on day 9 of the same or next menstrual cycle. Sonosalpingography was used as the reference standard for HSG. All patients with any positive findings underwent hysterolaparoscopy.
Results: For evaluation of tubal patency, SSG had sensitivity of 95.83% and specificity of 100% for evaluation of tubal patency. In contrast, in HSG for evaluation of tubal patency, the sensitivity is 91.67% and specificity is 100%.
Conclusions: Sonohysterosalpingography appears to be inexpensive, minimally invasive, quick, of no risk of ionizing radiation, and well-tolerable first-line diagnostic method for determining the tubal status and uterine cavity and can be performed at the time of conventional ultrasound scan in place of HSG and laparoscopy.
