Results: 504 aborted women were studied, 35% were missed abortion. According to risk factors there was a history of PID among 21%, HB<10mg/dl in 18%, and 17% had no history of prior disease. Previous Caesarean section presents in 14%. 14% of missed abortions were among the nulliparous women. TB has an incidence of 3% and 5% had history of toxoplasmosis. G2 was (17%), G5 (16%), G11(1%) and G12 (2%). 8 weeks fetus was (26%) and G19 and G20(1%). In our research 59% patients had no bleeding and 30% had spotting. In this research 35% patients had family marriage. According to treatment we used medical treatment for 58%, 29% surgical teatment and 13% had both medical and surgical treatment. Conclusions: In this study we have found that risk factors are the most critical causes of missed abortions, especially in third world countries like Afghanistan. Infections like PID, TB, and TORCH has still high rates in Afghanistan. Anemia, history of smoking and first pregnancies have high risks of abortions. Although the medical treatment is the preferred method in our research, some patients still use surgical treatment. To reduce the rate of missed abortion, it is necessary to conduct programs of education among women and treat the infections accordingly.
