Renal calculi and biochemical abnormalities. In children with myelomeningocele and heoconduit diversion.

Of 38 pediatric cases of ileoconduit urinary diversion of myelomeningocele, 4 with renal calculi are presented. An increased risk of renal calculus formation may be imposed on children with myelomeningocele with ileoconduit urinary diversion especially so in functionally and anatomically abnormal kidneys and in chronic renal infection with urea-splitting bacteria. It is not clear why the ileoconduit procedure should increase the incidence of renal calculi in such children.
