I had my J pouch removed after 30 years and opted to get a BCIR (similar to a Kock pouch), a continent internal pouch that does not require having an external bag. The stoma is located below the belt line and covered with a small absorbent dressing. The pouch is emptied 3-5 times a day at your convenience using a small plastic catheter and there is no leakage. I can wear any clothing I want and nothing about my procedure is visible. I can sleep on either side with no problems. I do not know if you are aware of this option or would be a candidate for it. Please feel free to send me a PM with any questions that you have.
