Abstract

ABSTRACT We report a case of urethral obstruction due to seminal vesiculitis in a Dorper sheep, with symptoms of anuria, rectal prolapse, orchitis/epididymitis, and uroperitoneum and biochemical tests indicating severe azotemia. The animal died due to advanced azotemia, and necropsy revealed kidneys with cortical and medullary necrosis, pyelonephritis of renal calyces, hydronephrosis, ruptured and necrotic bladder, and vesicular, bulbourethral, and ampoule accessory sex glands. There was prostate hyperplasia that revealed a large amount of pus in the cross section, which was also observed bilaterally in the epididymis and right testis. Morphotintorial and biochemical analyses of bacteria obtained from microbiological culture revealed Corynebacterium sp. and Escherichia coli. Infection, hyperplasia, and abscessation of accessory sex glands caused urethral compression, resulting in an obstructive condition, similar to urolithiasis, in addition to bacteremia. Hyperplastic seminal vesiculitis, although rare, must be included among the differential diagnoses of obstructive processes in the urinary tract of sheep.

绵羊精囊炎引起尿道梗阻一例报告

摘要：我们报告了一例因精囊炎引起的多尔珀羊尿道梗阻，其症状包括无尿、直肠脱垂、睾丸炎/附属炎和腹膜炎，生化测试表明严重的氮质血症。该动物死于晚期氮质血症，尸检显示肾脏皮质和髓质坏死、肾盏肾盂肾炎、肾积水、膀胱破裂和坏死，以及膀胱、延髓和安瓿附属性腺。前列腺增生，横截面可见大量脓液，双侧附睾和右侧睾丸也可见脓液。从微生物培养中获得的细菌的形态和生化分析揭示了棒状杆菌和大肠杆菌。副性腺的感染、增生和脓肿导致尿道压迫，除了菌血症外，还会导致类似尿石症的阻塞性疾病。高塑性精囊炎虽然罕见，但必须纳入绵羊尿路梗阻过程的鉴别诊断。
