Objective— To assess cystoscopic transurethral resection (TUR) for the palliative management of dogs with neoplastic infiltration urethra. Study Design— Prospective clinical trial. Animals— Six client‐owned dogs. Methods— Cystoscopic examination and electrosurgical TUR were performed in urination difficulties caused by prostatic or urethral neoplasia. was a retrograde manner female antegrade male via exploratory celiotomy ventral cystotomy. used to determine extent involvement involved piecemeal removal tissue from lumen using an electrocautery cutting loop. Hemorrhage controlled cauterized roller‐ball. In 2 dogs, intraoperative radiation therapy (IORT) treat both neoplasia sublumbar lymph node bed. Surgical technique, complications, adjuvant treatment, outcome recorded. Results— 3 carcinoma transitional cell (TCC). 1 dog, attempted but not successful because cystoscope diameter. Iatrogenic perforation occurred during prolonged exposure lavage fluid resulted biochemical abnormalities consistent syndrome. Dysuria resolved 5 within 10 days TUR. Treatment‐related complications included urinary tract infection tumor seeding. Local progression metastasis all Conclusions— (in combination chemotherapy±IORT) rapid palliation carcinoma. TCC, however, cannot be recommended high intra‐ postoperative complication rate no improvement compared historical reports tube cystostomy. Clinical Relevance— is novel alternative does provide any advantages
