Few cases of management of pregnancy in patients with an artificial sphincter (AS) have been reported in the literature, but this situation is very likely to become increasingly frequent with the more frequent use of AS in children. The authors report the case of a pregnancy in a 36-year-old woman with lumbosacral spina bifida, treated by artificial urinary sphincter and augmentation enterocystoplasty. The pregnancy and vaginal delivery did not raise any particular problems. Vaginal delivery is possible provided several precautions are observed: pelvimetry, MRI at the 8th month of pregnancy and close collaboration between urologists and obstetricians near term. Emergency caesarean section should be avoided due to the risk of lesions caused by elements of the AS and the surgical difficulties related to the presence of the augmentation enterocystoplasty.
