[Exstrophy of the bladder and pregnancy].

Two patients with bladder extrophy who had been operated on during infancy (the one by reconstruction of the bladder and the other by Coffey's operation) had delivered by Caesarean section, in the one patient of one child and in the other of two normal children. They formed the basis of this study. Vesical extrophy or ectopia vesicae is a rare malformation (in 1/40 000 to 1/50 000 births). It occurs most often in male children. It can be associated with genital, urological and orthopaedic malformations. The principal complications that can occur in pregnancy are urinary tract infections, prematurity, malpresentations and genital prolapse. As far as the urological side is concerned the complications are of ureteric stones, metabolic troubles, stenosis or obstruction of the uretero-sigmoid anastomosis following Coffey's operation, and ileal prolapse if Bricker's operation had been undertaken. The ways in which the babies should be delivered are discussed, as are the risks of this malformation recurring in children who are born to mothers with vesical extrophy.
