From 1994 to 2004, Hill's Pet Nutrition received 4495 canine (65%) and feline (35%) uroliths from Benelux veterinary practitioners. They were sent to the Minnesota Urolith Center, USA for analysis. In 1994, 110 uroliths were analysed - 85% from dogs - and in 2003, 1067 uroliths were analysed - 59% from dogs. During this period, substantial changes were observed in composition. In 1994, 77% of the cats had uroliths composed of struvite, and 12% had uroliths composed of calcium oxalate. In 2003, feline uroliths were composed of 32% struvite, and 61% calcium oxalate. The same evolution was observed in the dogs. In 1994, 51% of canine uroliths were composed of struvite, and 33% of calcium oxalate. In 2003, 40% had struvite uroliths, and 46% had calcium oxalate uroliths. A significant effect of the size, the breed, and the gender were noticed in the dogs. The mean age of uroliths appearance was 7.3 years in the dogs and 7.2 years in the cats. The findings are similar to those previously published in the USA.
1994年至2004年期间，希尔宠物营养公司从比荷卢经济联盟的兽医从业者那里收到了4495块犬类（65%）和猫类（35%）尿石。这些尿石被送往美国明尼苏达尿石中心进行分析。1994年，分析了110块尿石，其中85%来自犬类；2003年，分析了1067块尿石，其中59%来自犬类。在此期间，观察到尿石成分发生了显著变化。1994年，77%的猫的尿石由鸟粪石组成，12%由草酸钙组成。2003年，猫的尿石中鸟粪石占32%，草酸钙占61%。犬类也观察到了同样的变化。1994年，51%的犬类尿石由鸟粪石组成，33%由草酸钙组成。2003年，40%有鸟粪石尿石，46%有草酸钙尿石。在犬类中，尿石大小、品种和性别有显著影响。犬类尿石出现的平均年龄为7.3岁，猫为7.2岁。这些发现与美国此前发表的结果相似。
