Abstract

Introduction: Molar pregnancy is one of the challenging problems in obstetrics and gynecology medicine. But the subsequent pregnancy outcomes are more important than molar pregnancy. Incidence probability of the subsequent molar pregnancy is an important question of patients with history of molar pregnancy. Therefore the study is to survey the subsequent pregnancy outcome after molar and normal pregnancy.
Methods: This analytical-descriptive study was carried out on 793 pregnant women with diagnosis of molar and normal pregnancy who referred to Emam Reza and Motazedi hospitals of Kermanshah, Iran during 2006 to 2011. Sampling method was available. Data were collected by a self made information form via interview. Data were analyzed by SPSS software (version 16) and chi-square, independent t-student and Levense tests. P value less than 0.05 was considered significant.
Results: The mean age of two molar and normal pregnancy groups were respectively 26.5 and 23.93 years. There were no significant differences between two groups in stillbirth, ectopic pregnancy, preterm labor and preeclampsia in subsequent pregnancy (p= 0.702). Abortion rate in molar group was significantly higher (p=0.0001). Interval between pregnancies was longer in normal group (p<0.001). Probability of subsequent molar pregnancies was 2.79% and the difference was significant between molar and normal groups (p=0.003).
Conclusion: Patients with molar pregnancies could be reassured that their subsequent pregnancy in general will not end in high-risk outcomes.
