  • A case of canine bladder transitional cell carcinoma treated with urethrocystectomy followed by total vaginectomy

<p>Transitional cell carcinoma (TCC) of the bladder is the most common urinary tract tumor in dogs, and its surgical treatment may involve partial or total cystectomy. Recently, an increasing number of cases of canine bladder TCCs have been reported using en bloc resection of the bladder and urethra, aiming to prevent a high recurrence rate. Here we report a case of canine TCC, which was first treated with en bloc resection of the bladder and urethra to the opening of the external urethral meatus, since no apparent vaginal tumor invasion was observed in the preoperative cystoscopy. However, surgical resection of the uterus, vagina, and vulva was later performed since histopathology revealed tumor invasion of the resected margin, on the urethral side. After the second surgery, histopathology revealed no tumor cells in any resection margins, suggesting the complete resection.</p>
