All women underwent a standardized interview, pelvic organ prolapse quantification (POP-Q) assessment and four-dimensional transperineal ultrasound. 2D oblique parasagittal ultrasound imaging was performed by rotating the transducer 10-20° from the midline to line up the main transducer axis with the fiber direction of the puborectalis muscle, followed by a full parasagittal sweep of the hiatus at rest. Postprocessing of archived ultrasound volume data was performed at a later date, blinded to all other data.

Differential diagnosis from other forms of gestational trophoblastic neoplasia (GTN) is critical owing to major differences in prognosis and treatment. Doppler measurement of uterine artery (UtA) pulsatility index (PI) has been proposed for the diagnosis and management of GTN. The aim of this study was to evaluate the added value of UtA-PI Doppler measurement during the standard transvaginal ultrasound (TVS) assessment, in patients with PSTT as compared to those with other GTN.</p><p><strong>Methods: </strong>This was a single-center prospective cohort study involving ultrasound assessment of all GTN cases referred to and treated at the trophoblast unit of San Raffaele Hospital, Milan, Italy, between 2011 and 2023. TVS assessment included: grayscale analysis for the detection of myometrial or endometrial abnormalities, color and power Doppler assessment of lesions with scoring of vascularization, and spectral pulsed-wave Doppler for measurement of mean UtA-PI from the left and right UtAs. Sonographic findings were compared between patients with PSTT and those with other forms of GTN (postmolar, invasive mole or choriocarcinoma), using non-parametric two-tailed statistical analysis.</p><p><strong>Results: </strong>A total of 73 GTN cases were recruited, comprising nine (12.3%) with PSTT and 64 (87.7%) with other GTN. A significant difference was detected between other-GTN and PSTT cases when comparing rates of substantial endometrial vascularity on Doppler (50% vs 0%; P = 0.013) and mean UtA-PI measurements (median, 1.5 (interquartile range (IQR), 1.0-2.4) vs 2.2 (IQR, 1.5-2.7); P = 0.014; area under the receiver-operating-characteristics curve, 0.768 (95% CI, 0.610-0.888)).</p><p><strong>Conclusions: </strong>This study describes UtA-PI as a novel and effective marker allowing for the ultrasound differentiation of PSTT from other forms of GTN.
