We present our experience in seven patients (three boys and four girls) with bladder augmentation. Two patients had a neurogenic bladder, two a "nonneurogenic" neurogenic bladder and three a bladder exstrophy. Between the exstrophy patients, two had a rectocistoplasty and one a colon conduit diversion. The rest of patients (two neurogenic bladders and two "nonneurogenic" neurogenic bladder) had a colon conduit diversion. The intestinal segment used for bladder augmentation were ileocecal sement (two patients), ileon (one patient) and colon sigmoid (four patients). Bladder augmentation were tubularized in four patients and detubularized in three. In the follow-up, five patients have a normal renal function (one transplanted), one patient his function is unchanged and other is waiting for the transplant. Of the seven patients, six are fully continente day and night (two with CI and one with anticholinergic drugs) and one has a diurnal continence no more than two hours.
