Objective: Endometrial polyps are relatively common in reproductive and perimenopausal age group of women. It is an important easily treatable cause of AUB. With the advent of transvaginal ultrasound and saline sonohysterography more polyps are being diagnosed even in asyptomatic patients. The main aim of the study is to determine the efficacy of saline sonohysterography as an adjuvant to transvaginal sonography in detecting causes of AUB.
Study design: A Prospective Cohort Study was conducted on 50 patients in the reproductive and perimenopausal age group with complaints of abnormal uterine bleeding. Patients were selected based on selection criteria. Specific history with clinical examination and lab investigations were done. These patients were advised to undergo transvaginal sonography and saline sonohysterography.
Results: In the present study there was statistically significant association between the detection of endometrial polyp and the diagnostic method used either SIS or TVS [Chi-square value-6.383 and P value=0.012]. SIS detected seven endometrial polyp cases whereas TVS detected none. Therefore it was concluded that SIS is superior to TVS in detection of endometrial polyps. The diagnostic efficacy of both the tests were compared using paired “t “test showed significant difference between TVS and SIS [t-value-2.824 and P-value=0.007]. From the mean value observed it was concluded that SIS [mean=0.52060] is more effective than TVS [mean=0.44309]in detecting intrauterine pathologies.
Conclusion: In saline infusion sonohysterography saline outlines the uterine cavity and appears to be very sensitive in detecting endometrial polyps which are often missed by doing transvaginal ultrasound alone as diagnostic method. Thus saline infusion sonohysterography when combined with transvaginal sonography is more sensitive, accurate and simple method in detecting endometrial polyp as a cause of AUB
