尿石症是牛的一种常见病。结石在肾、输尿管、膀胱、尿道发生。发病率高,水牛可达8—10%,需手术治疗,经济损失较大。笔者根据150多例牛尿石症资料,调查分析了其发病因素,介绍如下。 相似文献

肉用公牛养殖受饲料、饮水等诸多因素的影响,极易导致各类疾病的发生,尿石症为肉公牛养殖的常见病,可对公牛健康产生极大的影响,严重的甚至会死亡,进而造成巨大的经济损失,阻碍肉牛养殖业健康发展。如何有效治疗肉用公牛尿石症成为研究思考的关键问题。基于此,着重对肉用公牛尿石症的中西医治疗方法展开深入研究,希望能够为该病的临床诊治工作起到一定的参考借鉴作用。 相似文献

在湖北地区对氟污染区及非氟污染区水牛尿氟含量进行调查分析,结果表明,水牛尿氟正常值中位数为1.97-3.13mg/L,95%上限值为3.63-6.36mg/L,尿氟含量与年龄有一定的相关关系。尿氟含量可作为反映机体摄氟水平的可靠指标,但用于慢性氟中毒中个例诊断的价值不大。 相似文献

随着天津及周边地区养猪业的规模化发展,一些以前不常见疾病的发病率愈来愈高,例如猪的尿石症,总是或暴发或散发地出现在猪群中。该病的发生将使养殖者遭受到一定的经济损失,甚至不得不淘汰病猪,即便如此,仍有些兽医人员和养殖业主对该病的认识不充分,下面笔者就近年来对该病的诊疗体会作一概述。猪的尿石症是指猪尿路中有机盐或无机盐类的结晶凝结物刺激尿路粘膜而引起的出血、炎症和阻塞的一种泌尿器官疾病。是在日常的饲养管理、气候或疾病等各种外界因素影响下机体内环境发生相对变化,导致正常尿液中的溶解态盐类晶体及胶体物质的相对平… 相似文献

泌尿系结石是指在泌尿系管道中异常矿化生成的结石性病变.根据构成结石的物质,可分为磷酸盐结石、尿酸盐结石、草酸盐结石、胱氨酸结石和碳酸盐结石;根据阻塞的部位,可分为肾结石、输尿管结石、膀胱结石和尿道结石,其中肾结石和输尿管结石合称上尿路结石,膀胱结石和尿道结石合称下尿路结石.近年来,临床中常遇到犬患下尿道结石的病例,该病在京巴犬、八哥犬、蝴蝶犬、西施犬及其同品种的窜种犬中发病率较高. 相似文献

A captive 5-yr-old castrated male Rocky Mountain wapiti (Cervus elaphus nelsoni) developed stranguria. Rectal palpation and physical examination indicated urethral obstruction that was subsequently relieved by urethrostomy and required only minimal aftercare. The wapiti was able to urinate freely after surgery; however, the obstruction recurred 27 mo later. Urethral catheterization relieved the second obstruction, which was caused by a large calculus composed of calcium carbonate and magnesium carbonate. Urolithiasis may have been associated with a diet high in calcium, and urethral obstruction may have been associated with castration at an early age. The wapiti continued to urinate freely 9 mo after relief of the second obstruction and 3 yr after the initial surgery. 相似文献

Two cases of patent ductus arteriosus are described in 2 Murrah buffalos, a 7.5-month-old heifer calf and a 5-month-old bull calf. The main clinical signs consisted of exercise intolerance, dyspnea, and tachycardia. At necropsy, lesions were consistent with congestive heart failure as indicated by dependent subcutaneous edema, body cavity effusions, and nutmeg liver. The lungs were extensively atelectatic. The heart was enlarged and had a globous shape. The ductus arteriosus, measuring 0.8 cm in length and 0.4 cm in caliber, was patent. The proximal pulmonary artery had an approximately 50-mm-long aneurysm. Eccentric cardiac hypertrophy was evident primarily in the right but to a lesser degree also in the left ventricle. Additionally, there was diffuse subendocardial fibrosis in the left and right ventricle. To the best of the authors' knowledge, patent ductus arteriosus was not previously described in buffalos. Since both calves were sired by the same bull, it is possible that this cardiac anomaly has a hereditary basis. 相似文献

The incidence and nature of urolithiasis in the cat is described. A new method for the relief of severe struvite urethral obstruction in the male cat is advocated, using retrograde irrigation with Walpole's acetic acid/ sodium acetate buffer pH 4.5. It is suggested that there is an essential physiological difference between stone-forming and non-stone-forming cats. The recurrence of urolithiasis in known stone-formers can be prevented by dietetic measures aimed at lowering both the specific gravity and the magnesium concentration of the urine. The effect of castration on the incidence of urolithiasis is discussed. Résumé. La fréquence et la nature de l'urolithiase chez le chat sont décrites. Une nouvelle méthode visant à soulager l'obstruction urétrale struvite aiguë chez le mâle est préconisée; elle consiste en une irrigation rétrograde à l'aide du tampon de Walpole imbibé d'acide acétique et d'acétate de sodium (pH 4,5). On avance qu'il y a une différence physiologique essentielle entre les chats prédisposés aux calculs et ceux qui ne le sont pas. On peut éviter un retour de l'urolithiase chex les chats qui y sont prédisposés en observant des mesures diététiques visant à réduire à la fois le poids spécifique et la concentration de magnésium dam l'urine. L'effet de l'émasculation sur les cas d'urolithiase est examiné. Zusammenfassung. Die Häufigkeit und der Charakter der Urolithiasis bei der Katze werden beschrieben. Eine neue Methode zur Beseitigung der schweren Struvitobstruktion der Harnröhre der männlichen Katze wird empfohlen, bei der retrograde Spülung mit Walpoks Essigsäure/Natriumacetatpuffer pH 4,5 angewendet wird. Es wird die Vermutung ausgesprochen, dass es einen wesentlichen physiologischen Unterschied zwischen steinbildenden und nicht-steinbildenden Katzen gibt. Das Wiederauftreten von Urolithiasis bei erkannten steinbildenden Katzen kann durch Emährungsmassnahmen verhindert werden, die darauf gerichtet sind, das spezifische Gewicht und die Magnesiumkonzentration des Urins zu senken. Der Einfluss der Kastrierung auf die Hädgkeit von Urolithiasis wird besprochen. 相似文献
