Introduction: 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. Material and method: 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 H20 (0.3-61.6). Detrusor overactivity is found in 72.2% and detrusor-sphincter dyssynergiain 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 dont 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 didnt 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.
