Bacteriologic culture results obtained before and after elective midtrimester urea abortion

Twenty patients undergoing elective midtrimester abortion by urea amnioinfusion had bacteriologic culture data obtained before and after the procedure. Despite the presence of pathogens in the vagina and cervix prior to the procedure, only 20% of patients exhibited endometrial growth following abortion. Factors that seem to favor such endometrial growth include increased injection-abortion intervals and the requirement for curettage to manage incomplete abortion.
