[Uterine rupture of the unscarred uterus. About 28 cases].
OBJECTIVE
To determine the etiologic factors explaining the appearance of uterine rupture on unscarred gravid uterus and to value the maternal and foetal prognosis of this complication.


METHODS
The authors report a study of 28 cases of uterine rupture on unscarred gravid uterus, recorded between January 1989 and December 1997, at the department of obstetrics and gynecology, Farhat Hached University Hospital, Sousse, Tunisia.


RESULTS
Out of the 72283 deliveries during the study period, there were 28 ruptured uteri of unscarred uterus giving a hospital incidence of one in 2581 deliveries. Multiparity, neglected labour dystocia and obstetric procedure were the common etiologic factors accused in the occurring of this complication. To be added to these factors: the low socio-economic status of the patients and lack of antenatal care. The surgical management was conservative (repair) in 19 cases (67.9%); hysterectomy was indicated in nine cases (32.1%). Maternal and fetal morbidity and mortality were important: we deplore two maternal deaths (7.1%) and seven fetal deaths (24.1%).


CONCLUSIONS
Uterine rupture on unscarred uterus is a relatively rare complication of the pregnancy. However, its incidence remains high in developing countries. Its occurrence is significantly associated with grandmultiparity, lack of antenatal care and low socio-economic status of the patients.
