Popis:	The gold standard for the treatment of invasive bladder cancer recognized throughout the world is radical cystectomy with orthotopic ileocystoplasty using the ileal intestinal tract. The study of the effect of urine on the adaptation of the mucosa of the artificial bladder continues for the last twenty years. According to the researchers, the results are quite contradictory, as some scientists note the hypersecretion of sulphomucins, sialomucins, progressive atrophy of microvilli, adenomatous hyperplasia and dysplasia. The aim of investigation to study the features of the histochemically revealed activity of succinate dehydrogenase in the wall of the artificial bladder and ileum in experimental animals. The material of the present study were the results obtained from the study of 18 female mini-pigs aged 4-5 months and weighing 8-10 kg. The modeling of the artificial bladder was performed in experimental animals, by cystectomy and subsequent ileo-cystoplasty. Experimental animals with a bladder model in groups of 6 animals were withdrawn from the experiment 3, 6 and 12 months after operational modeling. As for the wall of the official bladder, the changes in the activity of the studied enzymes were significant and showed not only possible changes in the activity of the Krebs cycle, but also about periodic displacements of the accents of substrate maintenance. These changes, in our view, are related to the transformation processes in the structural elements of the ileum wall, from which an unproblem has been formed to fulfill new functional duties. Signs of a violation of energy metabolism indicate the processes of hypoxia in the tissue of the artificial bladder and require further study and observation.
