Patients with malignant neoplasms of the bladder or severe anatomical and functional bladder abnormalities are the candidates for cystectomy and orthotopic urine diversion. The distal portion of the ileum is the most frequent anatomical organ, which is used for the formation of the urinary conduit. The formation of a urinary reservoir from the ileum that is unable to perform new functions, and mainly programmed to isolate enzymes, digest food and absorb nutrients, salts and minerals changes the energy exchange in the ileum wall under the influence of urine. The aim of the research is the examination of energy metabolism changes in the ileum wall during the formation of artificial bladder in experimental conditions conducted on mini-pigs. Experimental studies were performed on 21 female mini-pigs with an average age of 6 to 14 months. The duration of the experiment was 12 months. An imbalance of the ATP-ADP-AMP system was observed in the transplant tissue of the graft in different postoperative periods. Changes in the level of ATP are characteristics of the development of tissue ischemia. Results. The values of the adenosine nucleotides sum (the energy potential indicative of the respiration rate of mitochondria) and the phosphorylation index were lower at different times of observation in the transplant tissue. The energy charge value was lower to a lesser extent relative to the control. Conclusion. The revealed changes in the level of adenosine nucleotides confirm the severity of the disturbances of the energy homeostasis in the transplant tissue at all stages of the observation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
