BACKGROUND: To review the outcome of subsequent pregnancies in conservatively managed cases of uterine rupture. METHODS: Charts of patients with full thickness uterine rupture in the past 25 years were reviewed and information on subsequent pregnancies was extracted from maternal and neonatal charts. RESULTS: Thirty-seven patients with uterine rupture were identified; the uterus was scarred in 62.2%. Ruptures were repaired in 26 (70.3%). Twelve patients subsequently conceived (24 pregnancies), with recurrence in 8/24 (33.3%) pregnancies or 5/12 (41.7%) patients. Patients with recurrence had a shorter median interval from previous rupture (2 versus 5 years), a higher incidence of previous longitudinal ruptures (60.0% versus 0.0%), and the median gestational age at the preceding rupture was lower without reaching statistical significance (34 versus 38 weeks; p = 0.209). CONCLUSIONS: Longitudinal ruptures and short intervals between rupture and subsequent pregnancy predispose to recurrence of uterine rupture.
