title: [Vesicoureteral reflux in spinal cord injured patients. Treatment results and statistical analysis].
abstract: BACKGROUND
  VUR in spinal cord injured patients is cause of important morbidity and mortality. The aim of this paper is to make a statistical, retrospective and descriptive study to analyze VUR treatment results, in neurogenic bladder SCI patients.
  
  
  METHODS
  We study 40 patients (80 renal units) with VUR in neurogenic bladders and SCI, between March, 1990 and November, 2004. Median age is 43.05 y (9-76). 77.5% of patients are males (3.4:1). Time from injury to VUR is 24.7m (0.2-87). Median follow up is 8.23a (0.5-29). Traumatic lesions are most frequent (70%). Median bladder capacity is 244.9 ml (43-555) and median bladder compliance is 16.12 ml/cm H2O (0.3-61.6). Detrusor overactivity is found in 72.2% and detrusor-sphincter dyssynergia in 71.8%. Initial conservative treatment is done with indwelling catheter and anticholinergics
  
  
  RESULTS
  Complete remission was found in 57.5% of RU, descending VUR a 23.7% (66.2% previously to 42.5% after; p<0.02), and predominant in unilateral reflux. Partial response was found in 3.8%, progression in 12.5% and recidiva post CR in 10.9%. Younger patients have better remission rates (39.4 to 47.6 y; p=0.04). Urodinamycs variables don't found any significant differences in treatment results. Endoscopic treatment with bulking agents gets a good response rate (56.3%) (p=0.18).
  
  
  CONCLUSIONS
  Initial conservative treatment gets a 23.7% reduction of VUR, especially in men, young and unilateral reflux patients. Anyhow, we observe some progression and recidiva. Detrusor overactivity and detrusor-sphincter dyssynergia didn't influence in treatment results, but they are found in all patients with recidiva. With longer reflux evolution, we observe better responses, but also a higher recidiva rate (p=0.007). Endoscopic bulky injection techniques found out a good response rate (56.3%), also in patients with recidiva after conservative treatment.
