Comparison of diagnostic efficiency of transvaginal and transabdominal ultrasonography in intrauterine benign hyperplasia
Objective To compare the diagnostic efficiency of transvaginal and transabdominal ultrasonography in the diagnosis of uterine fibroids,adenomyosis and adenomyoma.Methods 41 cases of uterine fibroids,45 cases of adenomyosis and 38 cases of adenomyoma were confirmed by surgical histopathological examination.After admission,transvaginal and transabdominal ultrasonography were performed simultaneously.The detection rates of transvaginal and transabdominal ultrasonography in patients with uterine fibroids,adenomyosis,and adenomyomas were compared using pathologic findings as a control.The focus hemodynamics and color Doppler flow imaging(CDFI)blood flow signal classification were compared between transvaginal ultrasonography.Results The detection rates of hysteromyoma,adenomyosis and adenomyoma by transvaginal ultrasonography were 97.56%(40/41),95.56%(43/45)and 92.11%(35/38),which were significantly higher than 75.61%(31/41),73.33%(33/45)and 71.05%(27/38)by transabdominal ultrasonography,and the difference was statistically significant(P<0.05).The peak systolic velocity[(60.43±1.54),(67.80±2.42),(71.88±1.38)m/s],peak diastolic velocity[(4.28±0.35),(28.95±0.32),(5.54±0.28)m/s],pulsation index[(1.18±0.20),(1.38±0.15),(1.34±0.12)],resistance index[(0.55±0.16),(0.74±0.12),(0.76±0.10)]in patients with uterine fibroids,adenomyosis,and adenomyoma were compared,and the difference was statistically significant(P<0.05).The peak systolic velocity,peak diastolic velocity,pulsation index and resistance index of patients with adenomyosis and adenomyoma were higher than those of patients with uterine fibroids;the peak systolic speed in adenomyoma patients was higher than that in adenomyosis patients,and the peak diastolic speed was lower than that in adenomyosis patients.The difference was statistically significant(P<0.05).There were significant differences in CDFI blood flow signal classification among patients with uterine fibroids,adenomyosis and adenomyomas(P<0.05).Conclusion The detection rate of uterine fibroids,adenomyosis and adenomyoma by transvaginal ultrasonography is significantly higher than that by transabdominal ultrasonography,and the focal hemodynamic parameters and CDFI blood flow signal classification by transvaginal ultrasonography can improve the differential diagnosis effect of the three diseases.
