RESUMEN
Objective·To evaluate the clinical value of two-dimensional ultrasound combined with four-dimensional color Doppler ultrasound in the diagnosis of uterine space-occupying lesion.Methods·A total of 75 patients with uterine space-occupying lesion were enrolled in this study from March 2015 to February 2016 at Hospital of Southwest Medical University.Patients received both two-dimensional ultrasound and four-dimensional color Doppler ultrasound to determine the location,number and nature of the lesions,as well as the clinical staging of malignant lesions,then the diagnostic accuracy was evaluated.Results·Among 75 patients,there were 26 cases with endometrial carcinoma,21 cases with hysteromyoma,16 cases with metropolypus,and 12 cases with uterine adenomyosis.The diagnostic accuracy of two-dimensional ultrasound combined with four-dimensional color Doppler ultrasound for the uterine space-occupying lesion was 88.0％,which was significantly higher than that of two-dimensional ultrasound (64.0％) (P＜0.05).What's more,the diagnostic accuracy of two-dimensional ultrasound combined with four-dimensional color Doppler ultrasound for the clinical staging of endometrial carcinoma was 88.5％,which was significantly higher than that of two-dimensional ultrasound (61.5％) (P＜0.05).Conclusion·Two-dimensional ultrasound combined with four-dimensional color Doppler ultrasound is more effective to improve the diagnostic accuracy of uterine space occupying lesion and clinical staging of endometrial carcinoma in comparison with two-dimensional ultrasound,which will favor the clinical strategy for the treatment of uterine space-occupying lesion.
