Induction of therapeutic abortion by intra-amniotic injection of urea.

A new method of mid-trimester termination of pregnancy is described in which intra-amniotic urea was used. The mean interval between intra-amniotic injection and abortion was 59 hours and the mean length of hospital stay six days; the feto-maternal haemorrhage incidence was one out of 10 cases, which compares favourably with other methods. No complications have yet been encountered.
