Abstract

A selection of particular type of neurogenic bladder with a high risk for renal function from urodynamic study in myelodysplasia patients is important to predict prognosis and to determine treatment plan. With video urodynamic study we tried to know which type of bladder dysfunction had a possibility of renal deterioration. Among 39 patients with myelodysplasia. 10 patients had vesicoureteral reflux. In these patients. vesicoureteral reflux was found in 3 of 7 patients with hyperreflexia showing detrusor-sphincter dyssynergia, 2 of 6 patients with hyperreflexia without showing detrusor-sphincter dyssynergia and 5 of 10 patients with areflexia showing low compliance. All normal and any other areflexic bladders including relatively high compliance didn`t show vesicoureteral reflux. Upper tract dilatation also showed similar findings. These data show that with careful urodynamic study high risk neurogenic bladder type can be determined and it requires more aggressive treatment to preserve renal function.
