Details and patient eligibility

About

This study seeks to examine the response of the bladder to different pudendal nerve stimulation frequencies, by studying patients who have been previously-implanted with pudendal nerve neurostimulators.

Full description

The pudendal nerve goes to the urethra, anus, and other areas of the pelvic floor. Electrical stimulation of this nerve can help with bladder, bowel, and sexual problems, and pelvic pain. Researchers do not fully understand how the nerve helps with these functions or how the anatomy is different between people. Successful stimulation of the pudendal nerve may help improve medical care for future patients with bladder problems, pelvic pain, bowel problems, and/or sexual problems.
