The proportions of different urolith types have not been investigated in cats from the Republic of Ireland (ROI) and Northern Ireland (NI) previously. The objective of this study was to investigate the proportions of different feline urolith types submitted to Minnesota Urolith Center from the ROI and NI from 2010 to 2020. An additional aim of this study was to identify potential risk factors associated with each urolith type in cats in this geographic area. One hundred and thirty-one uroliths were submitted for the studied period with 44.3% being struvite, 43.5% calcium oxalate and 7.6% compound. Only 11 uroliths were submitted in the first 4 years. The number of submissions increased after 2015, peaking in 2019 with 25 submissions. Due to low numbers no conclusions could be made about changes in incidence of urolith types over time. Cats ≤7 years of age were significantly more likely to be diagnosed with struvite uroliths (OR, 2.87 [1.37-6.06]; p = 0.007) while cats ≥7 years of age with calcium oxalate uroliths (OR, 2.67, [1.29-5.37], p = 0.004). This is the first epidemiologic study of urolithiasis from cats in the ROI and NI. The most prevalent types of uroliths in our study population were struvite and calcium oxalate. Due to the low number of urolith submissions, changes in the incidence of different uroliths could not be accurately determined. Increasing age was associated with calcium oxalate formation while younger cats were more commonly diagnosed with struvite urolithiasis which can be medically dissolved. Therefore, urolith dissolution is more likely to be successful in young cats than older cats.

对来自爱尔兰共和国和北爱尔兰的 131 例猫科动物尿石的回顾性分析（2010-2020 年）

以前尚未在爱尔兰共和国 (ROI) 和北爱尔兰 (NI) 的猫中研究过不同类型尿石的比例。本研究的目的是调查 2010 年至 2020 年从 ROI 和 NI 提交给明尼苏达尿石中心的不同猫科动物尿石类型的比例。本研究的另一个目的是确定与猫中每种尿石类型相关的潜在风险因素这个地理区域。在研究期间提交了 131 块尿石，其中 44.3% 是鸟粪石，43.5% 是草酸钙，7.6% 是化合物。前 4 年仅提交了 11 块尿石。2015 年后投稿数量有所增加，2019 年达到顶峰，投稿 25 篇。由于数量较少，无法得出关于尿石类型发病率随时间变化的结论。年龄≤7 岁的猫更容易被诊断出患有鸟粪石尿石（OR，2.87 [1.37-6.06]；p = 0.007），而年龄≥7 岁的猫患有草酸钙尿石（OR，2.67，[1.29-5.37] ], p = 0.004)。这是 ROI 和 NI 中猫尿石症的第一项流行病学研究。在我们的研究人群中，最普遍的尿石类型是鸟粪石和草酸钙。由于提交的尿石数量较少，无法准确确定不同尿石的发病率变化。年龄的增长与草酸钙的形成有关，而年轻的猫更常被诊断出患有鸟粪石尿石症，这种疾病可以通过药物溶解。因此，与老年猫相比，年幼猫的尿石溶解更有可能成功。
