Dioctophymosis is a parasitic disease occasioned by the so-called "giant kidney worm", Dioctophyme renale, a nematode with an indirect life cycle. This parasite's definitive host is the mink, Mustela vison, though numerous wild and domestic mammals as well as man can serve as final hosts. The worms also can be in ectopic locations in the body. We surveyed 692 canines by ecography, urine sampling, surgery, necropsy, and clinical examination and diagnosed 244 cases of dioctophymosis (35.3%). Of the cases of dioctophymosis identified, 30.7% were obtained by ecography, 45.9% by urinalysis, and 17.6% by both those techniques -in addition to positive findings through surgery (2.5%), necropsy (2.5%), and the spontaneous elimination of the parasites (0.8%). Cases of dioctophymosis were observed in animals as young as 4months of age up to 15years. The frequency of D. renale diagnosis throughout the sampling period varied significantly. There was a statistically significant association between risk factors (swimming in the river, eating frogs, fish or eels, drinking ditch water) and the prevalence of infection. It was discussed the period missing after infection in canines.
膨结线虫病是一种由所谓的“巨型肾虫”——肾膨结线虫引起的寄生虫病，这种线虫具有间接生活史。该寄生虫的终末宿主是水貂，即美洲水鼬，不过许多野生和家养哺乳动物以及人类也可作为终末宿主。这些蠕虫在体内也可能处于异位。我们通过超声检查、尿液采样、手术、尸检和临床检查对692只犬进行了调查，诊断出244例膨结线虫病（35.3%）。在确诊的膨结线虫病病例中，30.7%通过超声检查发现，45.9%通过尿液分析发现，17.6%通过这两种技术均发现——此外，手术（2.5%）、尸检（2.5%）以及寄生虫自然排出（0.8%）也有阳性发现。膨结线虫病病例在4个月大至15岁的动物中均有观察到。在整个采样期间，肾膨结线虫的诊断频率差异显著。危险因素（在河中游泳、食用青蛙、鱼或鳗鱼、饮用沟渠水）与感染率之间存在统计学上的显著关联。文中还讨论了犬感染后缺失的时间段。
