Urodynamic studies in these cases revealed a change from detrusor hyperreflexia with detrusor external sphincter dyssynergia and high detrusor pressure to nearly normal storage and synergic voiding.

Of the 20 patients 17 (85%) gained acceptable bladder storage and emptying functions. These children were able to initiate voiding spontaneously and regained continence as early as postoperative month 6.
This procedure was designed to allow patients to initiate voiding voluntarily by scratching the ipsilateral L5 dermatome after axonal regeneration。
