Surgical management of incontinence in bladder exstrophy

Abstract

Between 1978 and 1990, 86 patients with previously closed classical bladder exstrophy and 10 patients seeking undiversion have presented for continence management and have undergone selective reconstruction designed for voiding and/or intermittent urethral catheterisation. The reconstruction in these 96 patients has been reviewed. Eight of the 10 patients undergoing undiversion achieved a satisfactory state of continence but 4 required Mitrofanoff procedures to enable catheterisation. Of the other 86 patients, 2 reached a satisfactory state of continence without further surgery; 79 underwent bladder neck surgery for continence either without augmentation (n = 32) or with augmentation (n = 47). Twenty of the 32 patients who were treated by bladder neck reconstruction alone were later found to require augmentation. Five patients had very early augmentation either to facilitate neonatal closure or on account of severe upper tract dilatation. Of these, 1 became continent without further surgery and 4 demonstrated the need for bladder neck reconstruction. Thus 12 children achieved successful continence (n = 6) or are evolving satisfactorily with potential success (n = 6) as a result of bladder neck reconstruction. Of the 71 patients requiring bladder neck reconstruction and augmentation, 68 have completed their surgery. The current status of these patients is: satisfactory in 57 (80%) (42 void/urethral clean intermittent catheterisation (CIC), 7 waiting to learn CIC, 5 Mitrofanoff, 3 artificial urinary sphincter (AUS]. Of the remaining 11 patients (20%), 8 are unsatisfactory to varying degrees and the status of the other 3 is unknown.
