[Cystometric examination for neurogenic bladder of neonates and infants].

We examined 38 neonates and infants with spina bifida using cystometry and cystography. Among 18 cases with myelomeningocele, only 1 case was evaluated as normal, 15 cases were abnormal on cystometry and 2 cases were unable to be evaluated. In the 15 abnormal cases, 8 had low-compliance and high pressure pattern which suggested future deterioration of upper urinary tract. Clean, intermittent catheterization was started in 3 cases. In 20 cases with spina bifida occulta associated with lipoma, 14 were evaluated as normal but 5 were abnormal and 1 case was unable to be evaluated. One of the 4 cases with low-compliance and high pressure was treated with clean, intermittent catheterization. Cystometric examination is a simple and useful modality in neonates and infants with neurogenic bladder not only to evaluate the function but also to predict the future deterioration of the upper tract, and to select the proper treatment.
