A retrospective analysis of urolithiasis in the dog was done at the Animal Medical Center, New York, NY, and involved a review of case records from Jan 1, 1968, to June 30, 1974. The study involved a total of 438 dogs that had a total of 561 urolithic episodes. Of the 438 dogs, 111 had 155 known recurrences of calculi. The types of recurrent calculi were phosphate (54 dogs), cystine (45 dogs), urate (7 dogs), oxalate (3 dogs), and carbonate (2 dogs). Two-thirds of the recurrent cases involved only 2 episodes. One-half of the population was composed of mixed breeds, Schnauzers, and Poodles. With the exception of 25 females that had phosphate calculi, all of the dogs with recurrences were males. Sixty-six dogs were tested for urinary bacteria and of these dogs, 40 had infected urinary tracts. The infected dogs had both phosphate and cystine calculi. In addition, most dogs with phosphate calculi had Staphylococcus infections, whereas the cultures from the dogs with cystine calculi had a wide range of bacteria.
纽约动物医疗中心对犬尿石症进行了一项回顾性分析，回顾了1968年1月1日至1974年6月30日的病例记录。该研究共涉及438只犬，总计发生561次尿石症发作。在这438只犬中，111只出现了155次已知的结石复发。复发结石的类型有磷酸盐结石（54只犬）、胱氨酸结石（45只犬）、尿酸盐结石（7只犬）、草酸盐结石（3只犬）和碳酸盐结石（2只犬）。三分之二的复发病例仅发作2次。一半的犬为混种犬、雪纳瑞犬和贵宾犬。除25只患有磷酸盐结石的雌性犬外，所有复发结石的犬均为雄性。对66只犬进行了尿细菌检测，其中40只犬的尿道受到感染。受感染的犬同时患有磷酸盐结石和胱氨酸结石。此外，大多数患有磷酸盐结石的犬感染了葡萄球菌，而患有胱氨酸结石的犬的培养物中有多种细菌。
