RESUMO
AIMS: The vast majority of spinal cord lesions cause neurogenic bladder disorders. Detrusor hyperreflexia presents a major risk factor for renal damage in these patients. We evaluated the long-term results of patients with spinal cord injury treated at our institution. METHODS: Eighty spinal cord injury patients (60 male, 20 female; mean age 29.6 years) with at least one follow-up visit a year for a minimum of five consecutive years, were included in this retrospective analysis. Follow-up included urodynamic evaluation, sonography of the upper and lower urinary tract, urine examination, and evaluation of renal function. Treatment modifications were based on the urodynamic findings. RESULTS: Mean follow-up was 67.3 months (range 60-103 months). At initial presentation, 51 patients performed intermittent catheterization, 7 had indwelling catheters, 10 utilized reflex voiding, 2 patients presented with a Brindley stimulator, 10 patients used abdominal straining. At the end of our study, no patient had signs of renal damage. To achieve that goal, 8 patients underwent sphincterotomy, 3 received a Brindley stimulator, 3 underwent bladder augmentation, one Kock pouch was performed, and 12 patients were treated with botulinum-A-toxin injections in the detrusor. Twenty-two patients received intravesical anticholinergic therapy. In merely three patients, treatment was not modified during the entire follow-up. CONCLUSIONS: In the long term, treatment strategy of neurogenic bladder dysfunction in patients with spinal cord injury had to be modified in almost all patients. 18.8% underwent surgery. For protection of the upper urinary tract and maintenance of continence, regular urodynamic follow-up is warranted.
