Abstract
Detrusor and/or urethral sphincter dysfunction is associated with increased failure or complication of ureteral reimplantation. A group of 400 children who underwent ureteral reimplantation was reviewed and the failure rate was determined. Those patients in the primary reflux category who failed were reviewed in detail for voiding dysfunction. Excluding technical error or ureteral dysfunction, the greatest risk for failure or complication of ureteral reimplantation seems to be related to detrusor and/or urethral sphincter dysfunction. Voluntary detrusor-sphincter discoordination seems particularly prevalent in this high risk group. The findings are discussed in relation to the over-all management of these patients.
