A 2-year-old castrated male vietnamese pot-bellied pig examined because of stranguria was found to have severe dilatation and inflammation of the pelvic portion of the urethra accompanied by cystitis and pyelonephritis. The pig had apparently had chronic inflammation of the urinary tract that eventually progressed to incomplete obstruction of the urethra. However, the initial cause of the urinary tract inflammation could not be determined. Possible causes included chronic bacterial infection, traumatic injury during urethral catheterization, and injury to the urethral mucosa secondary to extreme acidification of the urine.
一头2岁去势雄性越南大肚猪因排尿困难接受检查，发现尿道盆腔段严重扩张并伴有炎症，同时存在膀胱炎和肾盂肾炎。这头猪显然患有慢性泌尿系统炎症，最终发展为尿道不完全梗阻。然而，泌尿系统炎症的初始病因无法确定。可能的原因包括慢性细菌感染、尿道插管过程中的创伤性损伤以及尿液极度酸化继发的尿道黏膜损伤。
