摘要
猫患上尿道上皮癌(UC)的情况并不常见,以前也没有观察到UC与长期留置的尿路植入物有关。一只 18 岁的雄性阉割家养短毛猫最初因血尿就诊,超声波检查诊断为右侧输尿管结石和严重的泌尿系统梗阻,因此需要植入右侧皮下输尿管旁路(SUB)装置。随后,该猫出现间歇性血尿和排尿困难,但膀胱超声检查未见异常,尿培养也未呈阳性。13 个月后,患者出现了难治性下尿路症状、氮质血症、SUB 装置的膀胱造口管部位出现增生性肿块以及左侧输尿管梗阻的迹象。患者接受了膀胱造口管修补术和左侧 SUB 装置置入术,并进行了部分膀胱切除术以切除肿块。经组织病理学检查,肿块被诊断为 UC。据我们所知,与 SUB 装置中长期留置的膀胱造口导管组件相关的 UC 在兽医学中还没有报道过。
Urothelial carcinoma associated with a long-term indwelling cystostomy component of a subcutaneous ureteral bypass device in a domestic shorthair cat
Urothelial carcinoma (UC) occurs uncommonly in cats and no association has previously been observed with long-term indwelling urinary implants. An 18-year-old male castrated domestic shorthair cat initially was presented for hematuria, leading to the diagnosis of a right-sided ureterolithiasis and severe pyelectasia on ultrasound examination, prompting right-sided subcutaneous ureteral bypass (SUB) device placement. The cat subsequently had intermittent hematuria and dysuria, without ultrasonographic abnormality of the bladder or positive urine culture. Thirteen months later the patient developed refractory lower urinary tract signs, azotemia, a proliferative mass in the region of the cystostomy tube component of the SUB device and evidence of left ureteral obstruction. Cystostomy tube revision and left-sided SUB device placement were performed, as well as a partial cystectomy for removal of the mass. Upon histopathology, the mass was diagnosed as a UC. To our knowledge, UC associated with a long-term indwelling cystostomy catheter component of a SUB device has not been reported in veterinary medicine.
