Doppler Flow in Tubal Ectopic Pregnancy in Diagnosis as a Predictor of Treatment Success - Conservative and MTX Treatment

Study Objectives: * Primary Objectives: Assess the predictive value of Doppler flow parameters (RI, PI, and PSV) at diagnosis for conservative management success or MTX therapy success in tubal ectopic pregnancies. * Secondary Objectives: Evaluate the predictive value of additional parameters such as gestational age, yolk sac presence, embryonic pole presence, CRL, fetal heartbeat, abdominal fluid, pain severity, vaginal bleeding, and β-hCG levels. Study Design: * Prospective study including women diagnosed with tubal ectopic pregnancy. * Participants must be hemodynamically stable with no suspicion of tubal rupture. * Doppler parameters and clinical/laboratory data will be recorded at diagnosis, followed by treatment based on departmental protocols. Population: * Women aged 18-45 diagnosed with tubal ectopic pregnancy. * Inclusion and exclusion criteria based on stability, location of ectopic pregnancy, and lack of rupture suspicion. Sample Size: Based on previous studies, 60 participants (to allow for 10% loss to follow-up) will provide 80% statistical power to evaluate Doppler parameters as predictors of treatment success. This study aims to address the gap in the literature regarding the role of Doppler vascularization in predicting treatment outcomes for tubal ectopic pregnancy.
