A newborn (5 h old) quarter horse colt was presented because of lethargy and severe abdominal distention. Uroperitoneum was suspected during initial workup, based on sonographic imaging and peritoneal fluid analysis. Definitive diagnosis was confirmed during exploratory celiotomy. Surgery revealed a congenitally abnormal allantoic stalk/urachal remnant and a failure of embryological fusion of the dorsal bladder wall. Recovery was successful and the animal is now a healthy, 4-year-old western performance gelding. These specific congenital abnormalities have not been previously documented in the peer-reviewed literature. Key clinical message: Congenital abnormalities of the urachus and the urinary bladder should be suspected in foals with uroperitoneum at birth. Cases involving congenital abnormalities of the urachus and urinary bladder might have favorable prognoses if animals retain adequate function of the urogenital tract and do not have secondary complications before and following surgery.
一只 5 小时大的新生夸特马驹因嗜睡和严重的腹部膨胀而被送诊。根据初步的超声成像和腹腔液分析，怀疑为尿腹。在剖腹探查中确诊。手术显示出先天性异常的尿囊柄/脐尿管残余物和背侧膀胱壁的胚胎融合失败。术后恢复顺利，该动物现在是一匹健康的 4 岁西部运动种公马。这些特定的先天性异常以前并未在同行评议的文献中记录过。关键临床信息：出生时有尿腹的小马驹应怀疑脐尿管和膀胱存在先天性异常。如果动物保留了泌尿生殖道的足够功能，并且在手术前后没有出现继发性并发症，那么涉及脐尿管和膀胱先天性异常的病例可能有较好的预后。
