Summary Between them, three hospitals (University of Benin Teaching Hospital; Specialist Hospital and St. Philomena's Maternity Hospital) conduct about 80% of all deliveries in Benin City. A retrospective study of the records of these hospitals, was undertaken to determine the approximate incidence and the outcome of retained second twin in the City. During the study period, 1st January to 31st December 1979, there were 312 cases of retained second twins out of 1,790 total twin deliveries, giving an incidence of 17.43%. That retained second twin was a major cause of fetal wastage in this community was demonstrated by the high perinatal mortality rate of 231/1,000 in contrast to 56/1,000 and 38/1,000 respectively for non‐retained second and first twins. The causative factors were mainly malpresentation, uterine inertia, prematurity and failure of the mothers to utilize antenatal facilities. To reduce the incidence of retained second twin good antenatal care and early diagnosis of multiple pregnancy, are of paramount importance. Multiple pregnancy is a high risk pregnancy, therefore delivery should be conducted in a good obstetric unit with an experienced obstetrician in attendance.
