Indeed. also in some ops the part of the bowel responsible for B12 absorption can be affected (somebody correct me here if im wrong please) so you have to keep an eye on symptoms of B12 deficiency. In addition, the bowel that the neobladder is constructed from is designed to absorb and therefore, some items can be reabsorbed back into the body via urine. that said, nearly two years in and i haven't noticed too much part from being a bit looser than i used to be at times. you can control this to an extent with diet (acidophilus etc). there are psoting on these issues on the site
