【摘要】 尿路结石是犬常见的泌尿系统疾病之一，其形成与多种因素有关。为了解天津市部分地区犬尿路结石发病规律，于2022—2024年在天津市瑞派长江宠物医院向阳路店和迎水道店收集267例犬尿路结石病例信息，统计患犬性别、发病部位、年龄、品种、绝育/去势情况、饮食结构、结石成分信息并进行分析。结果显示，犬尿路结石的发病率为0.77%(267/34 760)，雄性犬（69.29%,185/267）占比显著高于雌性犬（30.71%,82/267）(P=0.012)；发病部位以膀胱为主，其中膀胱结石122例（45.69%），膀胱+尿道结石76例（28.46%）;7～9岁（43.45%,116/267）和大于9岁（27.72%,74/267）的犬发病率较高；贵宾犬（36.33%,97/267）发病率最高，其次为田园犬（27.34%,73/267）；未绝育/去势（65.17%,174/267）患犬发病率极显著高于已绝育/去势犬（34.83%,93/267）(P=0.003)；饮食以食用自制犬粮为主的患犬发病率最高（47.19%,126/267）。28例病例的结石中，磷酸铵镁结石占比最高（39.29%,11/28）。结果表明，天津部分地区膀胱结石患犬比例最高，尿路结石与犬的性别、年龄、品种、绝育/去势情况和饮食结构有关。本试验结果可为犬尿路结石的发病因素分析提供数据参考。更多还原

【Abstract】 Urolithiasis is one of the most common urinary system diseases in dogs, and its formation is associated with multiple factors.To investigate the epidemiological patterns of canine urolithiasis in parts of Tianjin, a total of 267 cases diagnosed between 2022 and 2024 were collected from Ruipai Changjiang Pet Hospital(Xiangyang Road Branch and Yingshui Road Branch).Case information, including gender, stone location, age, breed, neutering/spaying status, dietary structure, and stone composition, was statistically analyzed.Results showed that the incidence of canine urolithiasis was 0.77%(267/34 760).Male dogs(69.29%, 185/267) were significantly more affected than females(30.71%, 82/267)(P = 0.012).The most common site of occurrence was the bladder, with 122 cases(45.69%), followed by bladder + urethral stones in 76 cases(28.46%).Dogs aged 7–9 years(43.45%, 116/267) and over 9 years(27.72%, 74/267) were at higher risk.Poodles had the highest incidence(36.33%, 97/267), followed by Pastoral dogs(27.34%, 73/267).The prevalence was significantly higher in intact dogs(65.17%, 174/267) compared to neutered dogs(34.83%, 93/267)(P = 0.003).Dogs primarily fed homemade diets had the highest incidence(47.19%, 126/267).Stone composition analysis of 28 cases revealed that magnesium ammonium phosphate stones were most common(39.29%, 11/28).In conclusion, bladder stones accounted for the majority of canine urolithiasis cases in Tianjin.The disease was significantly associated with gender, age, breed, neuter status, and dietary structure.These findings provide valuable epidemiological data for analyzing risk factors of canine urolithiasis.更多还原
