Dimercapto-succinic acid scintigraphy and urodynamic studies are gold standards to evaluate renal scarring and neurogenic bladder dysfunction, respectively. We sought to establish the value of bladder wall thickness together with urine NGF, TGF-β1 and TIMP-2 to predict the urodynamic profile and upper urinary tract damage in children with myelodysplasia.

A total of 80 children with myelodysplasia underwent urodynamic investigation, bladder wall thickness measurement and dimercapto-succinic acid scintigraphy with basic neurourological evaluation. Two study and 2 control groups were created according to presence or absence of renal scarring on dimercapto-succinic acid scan (study and control groups 1) and according to detrusor leak point pressure greater or less than 40 cm H₂O (study and control groups 2). Urine samples were analyzed with ELISA.
