Abstract: Objective To investigate the video-urodynamics indication of upper urinary tract dilation secondary to neurogenic bladder that may be resolved only by intermittent catheterization. Methods From January, 2008 to August, 2016, twelve cases of upper urinary dilation secondary to neurogenic bladder were treated by intermittent catheterization only. Their clinical data was reviewed. Results The morphology and function index of upper urinary tract were improved gradually during the regular follow-ups. The common video-urodynamics characteristics include no detrusor overactivity, no vesicoureteral reflux, cysctometry volume larger than 300 ml and detrusor presser at the capacity lower than 40 cmH₂O, poor voiding efficiency with residual volume larger than 150 ml. Conclusion For upper urinary tract dilation secondary to neurogenic bladder characterized as passable storage and poor voiding, intermittent catheterization may be enough to resolve the dilation.
