Evaluation of Role of Transabdominal and Transvaginal Ultrasound in Diagnosis of Female Genital Tuberculosis.

BACKGROUND

Female genital tuberculosis (FGTB) is a common problem in developing countries causing significant morbidity, especially infertility. Radiological imaging, especially ultrasound, can help in diagnosis of FGTB with tubo-ovarian masses.

AIMS: The present study was performed to evaluate the role of ultrasound in diagnosis of FGTB and to see various findings of FGTB on ultrasound.

STUDY SETTING AND

DESIGN

It was a prospective cross-sectional study over 4-year period between August 2015 and August 2019 in a tertiary referral center.

SUBJECTS AND

METHODS

One hundred and seventy-five patients of infertility diagnosed to have FGTB on composite reference standard (CRS) of positive acid-fast bacilli on microscopy or culture of endometrial biopsy, positive polymerase chain reaction, positive GeneXpert, epithelioid granuloma on histology of endometrial biopsy, or definite or probable finding of FGTB on laparoscopy were subjected to transvaginal ultrasound by an experienced sonographer for various findings of FGTB.

STATISTICAL ANALYSIS: Data analysis was carried out using STATA software 12.0. Comparison of categorical values was tested using Chi-square Fisher's exact test, with P < 0.05 being taken as significant.

RESULTS

Mean age, body mass index, parity, and duration of infertility were 28.9 years, 22.9 kg/m2, 0.26, and 6.06 years, respectively. Menstrual dysfunction was common (44%). Diagnosis of FGTB was made by CRS. Ultrasound was normal in 112 (64%) cases and was abnormal in 63 (36%) cases. Various ultrasound findings were ovarian cyst (23.42%), tubo-ovarian masses (15.42%), unilateral or bilateral hydrosalpinx (13.71%), pyosalpinx (0.57%), adhesion (1.14%), adnexal fixity (6.28%), thin endometrium (24.57%), endometrial fluid (12.57%), endometrial calcification (1.7%), endometrial synechiae (4.57%), cornual synechiae (2.28%), impaired endometrial vascularity (21.71%), ascites (6.85%), and peritoneal or omental thickening (1.75%).

CONCLUSION

Carefully performed ultrasound is a useful modality in diagnosis of FGTB, especially in adnexal masses.
