We compared the results of intrathecal chemical rhizotomy performed in 3 patients, complete sacral rhizotomy in 3 and dorsal root ganglionectomy in 3. Dorsal root ganglionectomy (S2 to S4) obviated reflex bladder contractility and autonomic dysreflexia, and did not induce detrusor hypertonia. Chemical rhizotomy failed to abolish reflex activity or autonomic dysreflexia and was unsatisfactory. Complete intradural sacral rhizotomy obviated reflex activity and autonomic dysreflexia but induced detrusor hypertonicity and incontinence.
