Hi Cozy,
interestingly, I had an interstim implanted priority my ostomy and j pouch journey for fecal incontinence from an unrelated surgery.... I have had it turned off (its operated by a battery ) but am considering trying it again as I have had some urinary incontinence since the j pouch surgery 8 weeks ago. my doc said it may help.
I will keep you posted. feel free to let me know if you have questions!
