Diagnostic Accuracy of Hysterosalpingography in the Identification of Intrauterine Adhesions in Infertile Women in a Referral Centre, Southern Nigeria

Abstract

Background: Examination of the endometrial cavity is crucial in the management of infertile women. This evaluation is done by Hysterosalpingography (HSG) in the University of Port Harcourt Teaching Hospital. The diagnostic value and accuracy of hysterosalpingography varies in various centres and has not been assessed in the University of Port Harcourt Teaching Hospital (UPTH), hence this study. Methodology: A prospective cross sectional study done among 101 infertile women at the gynaecology clinic of the UPTH from December 2018 to July 2019. Socio-demographic data of women who met the eligibility criteria were collected. Their hysterosalpingographic and outpatient hysteroscopic findings were statistically analyzed using IBM SPSS for windows version 20.0. The validity and reliability statistics of hysterosalpingography for the identification of endometrial adhesions were determined and significance was reported at p-value Result: The respondents were all married, 66.3% of them were nulliparous, while 54.5% were above 35 years of age. Most, 93.1% of the studied group had at least secondary education and had duration of infertility of more than 2 years. There was a moderate strength of agreement in the diagnostic accuracy of HSG with hysteroscopy in the diagnosis of intrauterine adhesions; showing sensitivity and specificity of 59.6% and 90.9% respectively. The accuracy of HSG in the identification of intrauterine adhesions in this study was 73.3%. The agreement in the diagnostic accuracy of HSG using Hysteroscopy as a gold standard for intrauterine adhesions was therefore moderately significant (k = 0.482). Conclusion: HSG had an overall fair strength of agreement with office hysteroscopy in the identification of intrauterine adhesions. It is a specific but not a sensitive predictor of intrauterine adhesion.
