[Cystoplasties in children].

Whenever the reservoir function of the bladder is impaired (neuropathic bladder and exstrophy), an enterocystoplasty constitutes a satisfactory solution in children to enlarge the bladder. The various techniques must take into account the degree of alteration of the bladder. The bowel segment must be detubularized, regardless of its origin. The main challenge is to obtain adequate peripheral resistance with easy voiding and filling of the bladder without urine leak, particularly in boys. In girls, the combination of enterocystoplasty and Gobbel-Stockel procedure ensures perfect continence between two self-catheterisations.
