title: Urodynamic predictors of upper tract deterioration in children with myelodysplasia.
abstract: The clinical and urodynamic data of 62 children with myelodysplasia without previous urological treatment were tested statistically for the ability to predict upper tract deterioration. This was done by comparing these data among 26 children with dilated upper tracts and 36 children with normal upper tracts. Vesicoureteric reflux had a strong positive correlation with upper tract dilation but the maximum cystometric capacity, detrusor instability, compliance, maximum urethral closure pressure and peak flow rate all had no predictive value. Residual urine is sensitive and negatively predictive and leak pressure is specific and positively predictive; detrusor pressure at peak flow, opening pressure, pressure at least flow and the detrusor-adjusted mean passive urethral resistance relation factor (DAMPF) are sensitive and specific with high positive and negative predictive values.
