Objective To evaluate the value of transabdominal sonography(TAS),transvaginal sonography(TVS),sonohysterography(SHG),and hysteroscopy(HS) in the detection of endometrial pathology in the patients with uterine cavity lesions. Methods Uterine abnormality and disease were routinely examined by TAS, TVS, SHG.Results TAS was performed in 88 cases,TVS in 45 cases,SHG in 39 cases,and HS in 23 cases.Comparison was made between different means,showing SHG and HS with the highest sensitivity,accuracy and positive evaluation,respectively as 94.29%, 90.24%, 94.29%,and 95.65%, 91.67%, 95.65%.Conclusions Transvaginal sonohysterography is an easy, accurate,econimical,painless and no-injury technique for detecting endomatrial pathology and endoluminal masses.
