Abstract:
ObjectiveTo study the videourodynamic characteristics in spina bifida patients and to discuss the urodynamic risk factors causing the upper urinary tract deterioration.Methods33 cases with spina bifida were evaluated with non-complete synchronized videourodynamic test.Filling-phase function of bladder was evaluated with bladder sensation,detrusor activity,compliance,relative safe capacity,detrusor leak point pressure and presence of vesicoureteral reflux;voiding phase function was evaluated with detrusor pressure,the synergy between detrusor and external sphincter,the pressure-flow study.Patients were classified into upper urinary tract damage group and non-damage group according to the imaging and renal function test.The urodynamic parameters between the two groups were compared statistically.Results17 cases were found upper urinary tract damage(51%)in which 11 with vesicoureteral reflux and 6 was non-reflux hydronephrosis.Bladder compliance and relative safe capacity were significantly different between the two groups.ConclusionSpina bifida patients complicate a high incidence of upper urinary damage,especially vesicoureteral reflux.Low compliance and small relative safe capacity may be the major urodynamic risk factors causing upper urinary tract damage.
