  Abstract: Objective To investigate the value of transvaginal three-dimensional energy Doppler ultrasound (3D-PDU) in predicting pregnancy outcomes after mild and moderate uterine adhesion-release (TCRA). Methods Sixty-six patients with mild and moderate intrauterine adhesions (IUA) who had fertility requirements and were treated with TCRA surgery from January 2020 to December 2021 were selected. 3D-PDU examination was performed before and 3 months after surgery. Endometrial thickness (ET), uterine volume (EV), endometrial vasculogenesis index (VI), blood flow index (FI) and vasculogenesis - blood flow index (VFI) were recorded. The pregnancy was followed up for 12 months to observe the prognostic value of the above related indicators on postoperative pregnancy. Results The levels of ET, EV, VI, FI and VFI in 66 patients were increased after operation(P<0.05). The levels of ET, EV, VI, FI and VFI in the pregnant group were higher than those in the non-pregnant group (P<0.05). ET, EV, VI, FI and VFI levels predicted pregnancy after TCRA, and the subjects areas under the working characteristic curves were 0.80, 0.84, 0.68, 0.65 and 0.88, respectively. Conclusions The 3D-PDU test of endometrial thickness, volume and blood flow parameters before and after TCRA surgery in patients with mild and moderate IUA is helpful to predict the postoperative pregnancy outcome of patients and provide a basis for determining the follow-up treatment plan.
