A 4-month-old, 7 kg, intact male, Bernese mountain dog was presented for obstructive struvite ureterolithiasis. Multiple urethroliths, ureteroliths, and urocystoliths were present. Based on an abdominal ultrasound, there was severe left hydronephrosis and hydroureter from distal ureterolith obstruction, just proximal to the vesicoureteral junction. The dog was not azotemic. Successful treatment was accomplished ventral cystotomy. Bladder wall culture revealed a methicillin-resistant spp. No predisposing cause was identified. There are no known genetic predispositions in Bernese mountain dogs for struvite urolithiasis. The urinary tract infection resolved with surgical retrieval of the uroliths and antibiotic treatment. The dog remained clinically normal after the cystotomy but developed a subclinical urinary tract infection 4 mo post-operatively. Key clinical message: Urolithiasis is rare in pediatric veterinary patients. To the authors' knowledge, this is the first report of obstructive ureterolithiasis in a puppy. There is no known genetic predisposition for urolithiasis in Bernese mountain dogs.
一只4个月大、体重7千克、未绝育的雄性伯恩山犬因梗阻性鸟粪石输尿管结石前来就诊。存在多个尿道结石、输尿管结石和膀胱结石。根据腹部超声检查，由于输尿管远端结石梗阻，在膀胱输尿管连接处近端，左侧出现严重肾积水和输尿管积水。该犬没有氮血症。通过腹侧膀胱切开术成功完成治疗。膀胱壁培养显示一种耐甲氧西林的菌种。未发现诱发原因。伯恩山犬没有已知的鸟粪石尿石症遗传易感性。通过手术取出尿石和抗生素治疗，尿路感染得到解决。膀胱切开术后该犬临床症状保持正常，但术后4个月出现亚临床尿路感染。关键临床信息：尿石症在儿科兽医患者中很少见。据作者所知，这是幼犬梗阻性输尿管结石的首例报告。伯恩山犬没有已知的尿石症遗传易感性。
