PRECISION OF HYSTEROSALPINGOGRAPHY (HSG) IN THE DIAGNOSIS OF FALLOPIAN TUBE PATHOLOGY AMONG INFERTILE FEMALES
Objective: To determine the diagnostic precision of hysterosalpingography in the diagnosis of fallopian tube pathology among infertile females using laparoscopy as yardstick.
Study Design: Cross sectional validation study.
Place and Duration of Study: Armed Forces Institute of Radiology and Imaging, Pak Emirates Military Hospital Rawalpindi, from Feb 2015 to Aug 2015.
Methodology: Two hundred thirty patients who presented with infertility in Armed Forces Institute of Radiology and Imaging and satisfying the inclusion and exclusion criteria, were included. Informed consent was obtained before undergoing investigations, hysterosalpingography was performed at Armed Forces Institute of Radiology and Imaging and Laparoscopy by Gynecologist at Pak Emirates Military Hospital Rawalpindi.
Results: Total 230 patients were enrolled, ages were 32.39 ± 6.30 years. Frequency of tubal pathology in infertile women (on yardstick test) was recorded in 61 (26.52%). Diagnostic precision of hysterosalpingography for diagnosis of tubal pathology in infertile females taking laparoscopic findings as yardstick was recorded, true positive cases were 50 (21.74%), 11 (4.78%) were false negative, 20 (8.70%) were false positive and 149 (64.78%) were true negative. Sensitivity, specificity, positive predictive value and negative predictive value were calculated as 81.97%, 88.17%, 71.43% and 88.17% respectively.
Conclusion: There was higher diagnostic precision of hysterosalpingography in the diagnosis of fallopian tube pathology.
