| Popis: | The uterine tissue of three healthy nonpregnant goats was evaluated experimentally as a graft for closure of a bladder defect. Goats were subjected to ovariectomy, and then one detubularized uterine horn was used as a graft to close a large defect in the ventral aspect of the bladder. Follow up included monthly radiographic and ultrasonographic examinations and evaluations of kidney function and electrolytes changes for six months. The goats were euthanized after six months, and both the bladder and the graft were examined macroscopically and histologically. The technique required less invasive procedures than those described with alternative techniques of cystoplasty, achieved a high survival rate without life-threatening complications post surgery, was associated with no significant changes in kidney function and electrolytes levels, showed proper healing of the transplanted graft by regeneration rather than repair without scaring or fibrosis and with complete covering of the graft by a healthy urothelium and was associated with no malignant transformation. Hysterocystoplasty is a non-invasive, non-life-threatening technique due to the close position of the bladder to the uterus, and proper healing of the graft reflects absence of pressure on its blood supply. It is an acceptable alternative technique for closure of a large bladder defect and avoids disadvantages of alternative techniques of cystoplasty. It might be accepted by owners of pets, and further studies in clinical cases of dogs are advised. |
