A 3-year-old Thoroughbred colt was presented for evaluation of azotemia and anorexia. Physical examination revealed a ureterolith in the left ureter, approximately 10 cm from the bladder, which was thought to obstruct urine flow by approximately 90% when viewed cystoscopically. Ultrasonographic examination of both kidneys revealed indistinct corticomedullary junctions, and the right kidney was more hyperechoic. A percutaneous biopsy of the right kidney revealed chronic interstitial nephritis with marked interstitial medullary fibrosis. Medical therapy consisting of IV fluids, sodium chloride PO, and ammonium chloride PO was initiated. Ureteroscopic electrohydraulic lithotripsy via a perineal urethrostomy was used to successfully remove the stone. Klebsiella oxytoca, which responded to oral enrofloxacin therapy, was cultured from the urine after surgery. Azotemia resolved and the horse resumed training.
一匹3岁的纯种马驹因氮质血症和厌食前来接受评估。体格检查发现左输尿管有一个输尿管结石，距膀胱约10厘米，经膀胱镜检查，该结石被认为阻塞了约90%的尿液流动。对双侧肾脏进行超声检查发现肾皮质髓质交界不清，右肾回声更强。对右肾进行经皮活检显示为慢性间质性肾炎，并伴有明显的间质髓质纤维化。开始采用静脉输液、口服氯化钠和氯化铵的药物治疗。通过会阴尿道造口术进行输尿管镜电液压碎石术成功取出结石。术后从尿液中培养出产酸克雷伯菌，对口服恩诺沙星治疗有反应。氮质血症得到缓解，这匹马恢复了训练。
