Re evaluation of differential sacral rhizotomy for neurological bladder disease

The authors describe long-term follow-up results (4 to 6 years) in 13 patients who underwent differential sacral rhizotomy for urgency incontinence. Six patients were originally presented in a preliminary report in 1973. In the last seven patients, a highly selective rhizotomy of sacral fascicles innervating only the urinary bladder was performed. Results in the original six patients appear to be superior to those in patients who underwent a more refined rhizotomy. Possible explanations for this as well as alternative approaches to the treatment of urgency incontinence are briefly discussed.
