ANALYSIS OF BLADDER RELATED NERVE CUFF ELECTRODE RECORDINGS FROM PREGANGLIONIC PELVIC NERVE AND SACRAL ROOTS IN PIGS

Abstract

Cuff electrodes can be used to record bladder afferent information from the pelvic nerve and the sacral root S3 in pig. Pelvic nerve recordings were more selective than the sacral root recordings. Nerve activity increases were more distinct and repeatable during rapid bladder pressure changes and small spontaneous bladder contractions than during slow bladder fillings.
