Čutura Neđo, Soldo Vesna, Ćurković Aleksandar

Background/Aim. Uterine rupture at delivery is a severe life threatening complication for both matter and the newborn. The aim of the study was to determine the frequency of total number uterine rupture within the deliveries, to perceive circumstances and causes that lead to rupture, to establish perinatal and maternal mortality and to present our therapeutic procedure. Methods. In the group of 37 ruptures at 59 660 deliveries from the period 1991-2000 included in this retrospective study we analyzed age, level of education, gestational age, parity, previous caesarian section and other operations on uterus, time of diagnosing rupture, grade and place of rupture, use of Syntocinon and Prostaglandin at delivery, perinatal and maternal mortality, as well as therapeutic procedures at rupture that occurred. Results. The highest influence on uterine rupture in our group had been exerted by previous caesarian section and myomectomy in relation 33 : 4. Incomplete uterine ruptures were more frequent, 26 (70.27%), in relation to complete ones, 11 (29.75%). The most frequent place of uterine rupture was the front wall, 34 (91.89%), two ruptures occurred on the fundus and one on the back wall. The most frequently applied therapeutic procedures were rupture suture in 31 (83.78%) cases, and in six (l6.22%) cases hysterectomy. Perinatal mortality was three times higher than average (17.78‰) in that period and was 51.28‰. Conclusion. We emphasize that rupture frequency in the total number of deliveries was one rupture at 1 612 deliveries, whereas rupture frequency on the intact uterus was 1 : 17 269, and frequency of uterine rupture after caesarian section was one rupture at 245 deliveries. Our research as well as researches of other authors, showed that a previous caesarian section is the most frequent cause for the occurrence of uterine rupture. Therefore, caesarian section should be avoided whenever possible, not just because of a potential rupture, but also because of more frequent hysterectomy that interrupts woman's reproductive ability.
