Value of Transabdominal Combined Transvaginal Color Doppler Ultrasonography in the Distinguish between Uterine Adenomyoma and Uterine Fibroids

Abstract

Objective. To investigate the value of transabdominal combined transvaginal color Doppler ultrasonography in the diagnosis of uterine adenomyoma. Methods. A total of 80 patients with suspected uterine adenomyoma in our hospital from January 2019 to December 2021 were selected as the study subjects. All of them were examined by transabdominal color Doppler ultrasound (TA-CDUS) and transvaginal color Doppler ultrasound (TV-CDUS), and the postoperative pathological examination results were taken as the gold standard to analyze the diagnostic efficacy of different examination methods for uterine adenomyoma. Results. By postoperative pathological biopsy, 46 cases (57.50%) were diagnosed as positive and 34 cases (42.50%) were diagnosed as negative, including 29 cases of uterine adenomyoma and 5 other cases. The sensitivity, accuracy, and negative predictive value of TA-CDUS combined with TV-CDUS in the diagnosis of adenomyoma were higher than those of TA-CDUS ( $P<0.05$ ), and the Kappa value between TA-CDUS and pathological diagnosis was 0.923, which was higher than the 0.615 between TV-CDUS and pathological diagnosis. TA-CDUS combined with TV-CDUS showed that there were significant differences in the distribution of Adier blood flow grades between patients with uterine adenomyoma and uterine fibroids ( $P<0.05$ ), and the Adier blood flow grades of patients with uterine adenomyoma were mainly grade 0 and grade I; and the resistance index (RI), peak systolic velocity (Vs), and pulsatile index (PI) in patients with uterine adenomyoma were higher than those in patients with uterine fibroids ( $P<0.05$ ). Conclusion. Compared with TA-CDUS, TA-CDUS combined with TV-CDUS is more sensitive and accurate in the diagnosis of uterine adenomyoma and has a good consistency with pathological diagnosis results. Attention should be paid to the blood flow parameter values in the differential diagnosis of uterine fibroids.
