Comparative study of transabdominal ultrasonography and transvaginal ultrasonography in the diagnosis of submucosar hysteromyoma

Objective To evaluate the application of transabdominal ultrasonography and transvaginal ultrasonography in the diagnosis of submucosar hysteromyoma.Methods 124 cases of patients with submucosar hysteromyoma diagnosed by post-surgical pathology was selected,and a retrospective analysis was therefore made on the differences of accuracy between transabdominal ultrasonography(TAUS) and transvaginal ultrasonography(TVUS).Results 59 cases of these patients were examined by TAUS,in which there were 35 patients with submucosar hysteromyoma while the other 24 cases were misdiagnosed,and the accuracy rate was 59.3%.Other 65 cases of patients were examined through TVUS,59 of which with submucosar hysteromyoma were diagnosed,only 6 patients were misdiagnosed,and the accuracy rate was 90.8%.There was significant difference between the two ways of ultrasonography(P0.01).Conclusion It is suggested that TVUS shows an obvious priority than TAUS in the detection of submucosar hyteromyoma with dimentions less than 3 cm.
