title: Clinical and radiological findings following continent urinary diversion with colonic segment in dog.
abstract: In order to assess clinico-radiological findings of urinary diversion, five adult healthy mongrel dogs of both sexes weighing between 25-40 kg and average age of 1.5 years, underwent continent urinary diversion surgery. In this approach fifteen centimeters of the descending colon with preservation of its mesenteric vessels was resected and this segment longitudinally was opened and flushed with an aqueous solution of povidin iodine 0.1% and the remaining colon re-anastomosed by seromuscular sutures. Then two ends of transected ureters were drawn into the resected colon by mosquito hemostatic forceps and simple interrupted sutures were placed between the ureter and the colonic mucosa for uretero-colonic anastomosis. The uretero-colonic part in a cap form transplanted to partially cystectomized bladder with one layer of cushing pattern suture. All animals survived after the operation. Clinically, all dogs were dull and depressed and passed blood tinged urine for first few postoperative days. There was pollakiuria in all of animals distinctly, but urinary incontinence was not observed. At the first few postoperative days, anorexia, nausea and vomiting were seen in three dogs. In all animals, polydipsia were seen and continued until the end of study. Intravenous urograms showed hydronephrosis and upper urinary tracts dilatation in all animals at 25th day but there were signs of improvement at 45th day distinctly. Unilateral ureteral obstruction was observed in two dogs. In regards to clinico-radiological findings can be concluded that this operation has some distinct sequela that some of them may be seen in radiographic assessments.
