[Renal outcome in myelodysplastic patients with untreated, risky vesico-sphincter dysfunction].

Poor vesical accommodation with competent sphincter system and bladder-sphincter dyssynergy are major risk factors for renal function in patients with myelomeningocele. We present four cases with these urodynamic features and we analyse renal variation with time in relation to these, pointing out the poor evolution. We emphasize the need for urodynamic study with simultaneous radiology and early treatment when these risk factors exist.
