Abstract

Continence is the main goal in the treatment of patients with bladder exstrophy and prognosis is necessarily long-term. Over an 8-year period, 44 patients presented with bladder exstrophy and/or incontinent epispadias. Twenty-five bladder closures (7 secondary), 23 male urethroplasties, 19 bladder neck (BN) reconstructions and 6 bladder augmentations were performed in these patients. In 18 children 2 additional procedures were employed in the last 3 years: female genito- urethroplasty (15) and submucosal periurethral collagen injection (11). Eight children underwent both procedures. Genito-urethroplasty and collagen injection were performed before BN reconstruction in 6 and 5 cases respectively, in order to increase bladder outlet resistance. The submucosal injection was performed at 3, 9 and 12 o'clock in the BN or sphincteric urethra, using 0.75 to 2.5 ml of crosslinked bovine collagen. Continence in the children who underwent the complete staged reconstruction was good in 58%, fair in 32% and poor in 11%. Following female genito-urethroplasty and periurethral collagen injection, bladder capacities increased by 25%. These complementary procedures are effective in increasing outlet resistance and bladder capacity in patients with exstrophy and/or epispadias; they may improve continence and lessen the need for further bladder augmentation.
