This Prospective study will be conducted To copare uterine blood flow using Doppler ultrasound before and after evacuation of hydatiform mole between female patients with remissions and those with development of post-molar persistent gestational trophoblastic neoplasia to detect accuracy,efficacy,predictive value and acceptability of uterine artery doppler in predicting gestional trophoblastic neoplasia .
Patients with confirmed diagnosis of complete hydatiform mole.
Hemodynamically stable patient .
No contraindication for anesthetic materials used for the evacuation .
Acceptance of possible prolonged follow up , repeated uterine artery doppler ultrasound ,repeated HCG tests
Patient refusal to participate in the study.
Patient with incomplete hydatiform mole .
Patients who were lost during the follow-up period after this procedure.
Contraindication for anesthetic materials used for the evacuation .
