peroperative electrophysiological evaluation, patient education, discontinuation of anticholinergics, maintaining bladder capacity below 700 mL and leaving a suprapubic catheter in situ until reflex arch voiding was established. Although first published after beginning of the present study most criteria were met, save the upper limit of bladder capacity and cessation of anticholinergic medication, as we judged that the medication was essential for patient wellbeing throughout the 18 month study time. As reinnervation occurs at the level of the preganglionic (nicotinic) receptors, and anticholinergics mainly target postganglionic (muscarinic) receptors, we cannot exclude that treatment may have diminished the reflex but do not believe it would have abolished it completely.
