Ureteral stricture after radical cystectomy and cutaneous abdominal ureterostomy: case report

ABSTRACT This study aims to report the technique of total cystectomy associated with abdominal ureterostomy, a technique -little described in veterinary medicine, as well as to describe the postoperative complications observed. A male Akita canine, 11 years old, castrated, was attended with a history of prostration, hyporexia, dysuria, hematuria, and urinary incontinence for approximately ten days. The clinical examination revealed mild abdominal pain and other parameters within the normal range. Complementary imaging studies revealed the presence of mass involving a large part of the urinary bladder. The patient underwent total cystectomy surgery associated with abdominal cutaneous implantation of the ureters and histopathological examination led to a diagnosis of non-papillary infiltrative transitional cell carcinoma. In the postoperative period, the patient developed mild uremic dermatitis at the insertion site of the ureters and ureteral stenosis in the distal region, so that surgical reinterventions were necessary for correction. In addition, pyelonephritis and hydronephrosis secondary to the obstructive condition were observed. Due to the postoperative complications, the tutor chose to euthanize the dog. Thus, it is concluded that ureteral stenosis and pyelonephritis are possible complications of the cystectomy technique associated with abdominal implantation of the ureters.
