Ureteral reimplantation in children with neurogenic bladder

Abstract

The treatment of urologic complications from myelomeningocele and especially of vesico-renal reflux is a controversial problem. A series of 26 reimplanted ureters in 17 children, with good results in more than 85%, is reported. Ureteroneocystostomy, carried out with a few technical innovations, may represent a useful method for the treatment of vesico-renal reflux and obstruction of the ureterovesical junction in neurogenic bladder associated with myelomeningocele. This surgical approach leads to the disappearance of the reflux, decrease of dilatation of the upper urinary tract and preservation of renal function in most cases; moreover, infection can be more easily controlled. Ureteral reimplantation should be preceded by periodic urethral dilatation, external transurethral sphincterotomy, and pharmacologic regulation in order to attempt to decrease urethral resistance. After successful surgery, it is possible to try to reeducate the bladder. Reimplantation should be preferred to permanent urinary diversion even if there is gross reflux.
