The submission rates of feline uroliths to laboratories and the composition of uroliths have been reported in studies. The prevalence of uroliths reported on imaging findings has not been published. The objective of this retrospective study was to use imaging data to investigate the anatomical location and the prevalence of macroscopic uroliths in cats. Radiographs, sonograms and imaging reports from two cohorts of cats (from New Zealand ( = 497) and the United States ( = 693)) from 2004-2013 were reviewed for the presence of uroliths. Uroliths were categorized by their location in the lower or upper urinary tract. Radiographic studies were performed on 43% (212/497) of the cats from New Zealand and 50% (349/693) of the cats from the USA. Sonographic studies were performed on 57% (285/497) of the cats from New Zealand and 50% (344/693) of the cats from the USA. The total prevalence of uroliths was 3% in the New Zealand cohort and 13% in the USA cohort. Lower tract urolith prevalence in the New Zealand cohort was 2.4% (5/212) in cats ≤ 6y and 1.1% (3/285) in cats >6y. Upper tract urolith prevalence in the New Zealand cohort was 0.5% (1/212) in cats ≤ 6y and 1.8% (5/285) in cats >6y. Lower tract urolith prevalence in the United States cohort was 6.0% (11/183) in cats ≤ 6y and 2.9% (15/510) in cats >6y. Upper tract urolith prevalence in the United States cohort was 2.7% (5/183) in cats ≤ 6y and 10.2% (52/510) in cats >6y. The prevalence of uroliths in the upper tract or lower tract was low in the New Zealand cohort compared to that of cats in the USA cohort, irrespective of age category. Geographical location may be important when evaluating risk factors for feline urolithiasis.
已有研究报道了猫泌尿系统结石送检至实验室的比率以及结石的成分。关于影像学检查结果中泌尿系统结石的患病率尚未见报道。这项回顾性研究的目的是利用影像学数据调查猫体内肉眼可见的泌尿系统结石的解剖位置和患病率。对2004年至2013年两个猫群（来自新西兰（n = 497）和美国（n = 693））的X光片、超声图像及影像学报告进行审查，以确定是否存在泌尿系统结石。泌尿系统结石根据其位于下尿路还是上尿路进行分类。对43%（212/497）的新西兰猫和50%（349/693）的美国猫进行了X光检查。对57%（285/497）的新西兰猫和50%（344/693）的美国猫进行了超声检查。新西兰猫群中泌尿系统结石的总患病率为3%，美国猫群中为13%。在新西兰猫群中，6岁及以下猫的下尿路结石患病率为2.4%（5/212），6岁以上猫为1.1%（3/285）。6岁及以下猫的上尿路结石患病率为0.5%（1/212），6岁以上猫为1.8%（5/285）。在美国猫群中，6岁及以下猫的下尿路结石患病率为6.0%（11/183），6岁以上猫为2.9%（15/510）。6岁及以下猫的上尿路结石患病率为2.7%（5/183），6岁以上猫为10.2%（52/510）。与美国猫群相比，新西兰猫群中上尿路或下尿路结石的患病率较低，且与年龄类别无关。在评估猫泌尿系统结石病的风险因素时，地理位置可能很重要。
