Permanent cystostomy catheters were placed in 7 dogs to relieve urine outflow obstruction from presumed transitional cell carcinoma of the bladder trigone and urethra. The catheters were easily managed at home by the owners. Complications were minimal. The most frequent complication was urinary tract infection. Two owners complained of difficulty in draining the bladder 1 week before euthanasia of their dogs. The primary reason for euthanasia of all dogs was progression of the tumor. Survival times of these dogs were similar to those previously reported for dogs with transitional cell carcinoma involving the bladder and urethra, irrespective of treatment. Placement of a permanent cystostomy catheter should be considered in dogs with transitional cell carcinoma associated with urine outflow obstruction when, owing to the dog's condition or the owner's preference, radical surgery or other treatment is not an option.
对7只犬放置永久性膀胱造瘘导管，以缓解因膀胱三角区和尿道疑似移行细胞癌导致的尿液流出梗阻。导管在家中由主人轻松管理。并发症极少。最常见的并发症是尿路感染。两只犬的主人在其犬安乐死1周前抱怨膀胱引流困难。所有犬安乐死的主要原因是肿瘤进展。这些犬的生存时间与先前报道的患有累及膀胱和尿道移行细胞癌的犬相似，无论采用何种治疗方法。当由于犬的病情或主人的偏好，根治性手术或其他治疗不可行时，对于伴有尿液流出梗阻的移行细胞癌犬，应考虑放置永久性膀胱造瘘导管。
