OBJECTIVE To clarify the relation between metroplasty for correction of uterine anomalies and subsequent pregnancy, we reviewed the charts of all patients for whom a diagnosis of bicornuate, septate, or didelphic uterus had been made between 1972 and 1982 and analyzed their obstetric outcomes. METHODS Of the 146 patients evaluated, 23 received a metroplasty procedure, and 123 patients did not have surgical intervention. Fifteen of the nonsurgical patients could be matched with 15 of the surgical patients by age, chief complaint, gravidity, and type of anomaly and therefore served as matched controls. RESULTS The percentage of patients with living children after the diagnosis of uterine anomaly was 67% for the matched nonsurgical group and 73% for the patients who underwent metroplasty. The difference was not statistically significant. Although marked improvement in fetal salvage rates was noted when reproductive outcomes before and after metroplasty were compared, the obstetric outcome was similar to that of the control groups after the diagnosis was made and surgery deferred. CONCLUSIONS The efficacy of metroplasty in the treatment of multiple pregnancy losses is thus being questioned.
