RESUMO
Percutaneous chemical neurolysis of sacral nerve with phenol was performed on 11 cases of hyperreflexic bladder to augment bladder capacity and to make intermittent clean catheterization more feasible. Urodynamic evaluations were done before and after chemical neurolysis. Followup ranged from 10 months to 16 months(mean 13 months). Mean bladder capacity increased significantly after chemical neurolysis ( from 157.5ml to 340ml). No significant changes in bowel or injection sites were noted. Continence was improved in 100%, with 7 patients remaining completely dry and voiding with intermittent self-catheterization. The long term results were necessary but we considered the chemolysis of sacral nerve was available modality for hyperreflexic bladder patients, who did not respond to anticholinergic medication, before decide the more aggressive alternatives, such as augmentation cystoplasty or urinary diversion.
