A cat of serious bladder and urethra with feline lower urinary tract disease was performed trigonal-colonic anastomosis. Ureterocolonic anastomosis was performed in a dog with transitional cell carcinoma of urinary bladder and prostate, which caused urine outflow incomplete obstruction. Both cases had anal continence without urine leakage after surgery. Trigonalcolonic anastomosis and ureterocolonic anastomosis appear to be a worth procedure for dogs and cats with diseases of the urinary bladder which cannot recover the function by reconstructive surgery and are necessary to make an alternative urinary passage.
An 11-year-old female West Highland white terrier weighing 8.3 kg was diagnosed as pituitary -dependent hyperadrenocorticism with pituitary macroadenoma. Surgical excision of the pituitary macroadenoma and hormone supplment therapy was performed. The tumor was histologically diagnosed as ACTH-producing adenoma. After the surgery, increased ALP and Tcho levels observed preoperatively reversed to the normal ranges, and the result of ACTH stimulation test was markedly improved. The systemic skin disorders observed preoperatively also remitted gradually and completely healed after three months of the surgery. The clinical course of this case strongly suggested that hypophysectomy is a useful and effective treatment for canine PDH with macroadenoma when the disease was diagnosed in the early phase.
A right renal mass was detected in a sixteen-month-old female rabbit with anorexia and the resection was performed. In the preoperative blood examination, the packed cell volume and creatinin values were increased, and the total protein and albumine ones were slightly increased. The patient was suggested to be polycythemia and dehydration, but the blood urea nitrogen level was normal. The resected mass accompanied with hydronephrosis was diagnosed as nephroblastoma which was seen hemorrage and necrosis in the wide range. The rabbit was dead four days after surgery.
