Abstract

A 1-year-old intact male Russian blue cat was admitted with a history of depression, partial anorexia, vomiting and dysuria. Through the blood analysis, ultrasonography and urinalysis, this cat was diagnosed as feline lower urinary tract disease with cystitis. Despite antibiotic therapy the cat showed stranguria and urinary catheterization were repeated several times. One week after, this patient appeared depression, hyperthermia and leukocytosis. Ultrasonography revealed a small amount of hypoechoic fluid around the right kidney and bacteria were found in the urine. The amount of the right subcapsular fluid was increased and bacteria were found in the fluid. On the excretory urography, leakage of contrast media were detected. The right kidney was surgically removed and suppurative fluid between the renal parenchyma and the thickened capsule was identified. After surgery, subcapsular abscess of the right kidney associated with pyelonephritis was confirmed histologically and this cat recovered without complications.

한 살의 수컷 러시안 블루 고양이가 침울, 식욕저하, 구토, 배뇨장애를 주호소로 내원하여 방광염을 동반한 고양이 하부 요로계 질병으로 진단받았다. 입원 치료 시에도 배뇨곤란이 지속되어 요도카테터 삽입을 몇 차례 반복하였다. 일주일 뒤 환자는 침울, 발열, 백혈구증가증을 나타내었다. 초음파 검사 시 우측 신장 주변으로 소량의 저에코성액체가 보였고 요검사에서는 세균이 확인되었다. 이후 우측신장 피막하 액체의 양은 증가하였으며 흡입 시 세균이 관찰되었다. 배설성 요로조영술에서는 우측신장으로부터 조영제의 누출이 확인되었다. 수술적으로 우측신장을 제거하였으며 신장실질과 비후된 피막 사이에서 농성 삼출물을 확인하였다. 수술 후 환자는 합병증 없이 회복하였으며 조직학적으로 신우신염을 동반한 우측신장의 피막하 농포로 확진되었다.
