Background: Tubal problems associated with infertility can be due to blocked tubes, adhesion and scarring of the tubes and distal block leading to Hydrosalpinx. The objective of this study is to evaluate the accuracy and efficiency of Sonosalpingography in the assessment of tubal patency, in comparison to the gold standard method of laparoscopic Chromopertubation and to determine its value as a basic non-invasive screening procedure in infertile women.

Methods: A prospective study involving a series of 50 women including both primary and secondary infertility registered in the infertility clinic, Obstetrics and Gynaecology department, at Jubilee Mission Hospital for 1 year (June 2011 to June 2012). These patients after initial evaluation were subjected to sonosalpingography on one of the days between 5th and 10th days of the menstrual cycle for assessment of tubal patency. This was followed by laparoscopy with chromopertubation on the same day or next day. The results of the two tests were compared to determine the accuracy of these SSG.

Results: Mean duration of infertility 6-12 years of standard deviation (SD) from mean of 3.72 years. SE<0.4769 and 95% CI was 5.6 to 7.079 yrs. Sensitively for tubal patency with SSG compared to Laparoscopic chromotubation was 93.30% with 95% CI between 84.77 and 96.85.

Conclusions: If SSG is performed as a base line test, laparoscopy can be reserved for those women who have unexplained infertility or whose SSG is abnormal or whose medical history and physical examination reveal pelvic pathology.
