Abstract

Two year-old female miniature schnauzer was presented with depression, abdominal pain and inappetence. Physical examination revealed tachypnea, fever, and abdominal pain. Leukocytosis with neutrophilia was shown in complete blood count. Radiograph revealed the increase of opacity in parallel to vertebra and dislocation of descending colon. Calculi and sludge in bladder, hydronephrosis and dilation of proximal ureter in right kidney were observed in ultrasonographic examination; also, irregular shape of structure in retroperitoneal cavity was observed. Urinalysis showed protein urine and hemtauria. Many epithelial cells, spindle cells, calcium oxalate dihydrate crystals, struvite crystals, amorphous crystals and granular casts, WBC, cocci were examined in urine sediment test. ERD-kit test result was highly positive. Based on those test and excretory urogram pyelonephritis and complete unilateral obstruction of ureter were confirmed. A balloon type structure in retroperitoneal cavity was found through the exploratory laparotomy. In cytologic examination of aspirated fluid from dilated area many degenerated neutrophils and phagocytized cocci were observed. Staphylococcus intermedius was cultured from aspirated fluid. Based on these clinical results retroperitoneal abscesses caused by Staphylococcus intermedius was diagnosed with ureter obstruction and concurrent cystic calculi. Nephrectomy of right kidney with ureter was performed.

2년령의 암컷 miniature schnauzer가 침울, 복통 및 식욕부진으로 내원하였다. 신체검사를 통해 빈맥, 발열과 복통을 확인하였다. 총혈구계수 검사에서 호중구수의 증가를 동반한 백혈구증가증이 관찰되었다. 방사선 검사에서 하행결장의 변위와 척추와 평행하게 방사선투과가 감소한 부위가 관찰되었다. 초음파검사시 방광내 결석과 슬러지, 우측 신장의 수신증 및 근위뇨관의 확장이 관찰되었다. 뇨검사결과 단백뇨와 혈뇨가 나타났으며 뇨침사검사에서 다수의 상피세포, calcium oxalate 결정, struvite 결정, 무정형 결정과 과립원주, 백혈구 및 구균이 관찰되었다. 상기의 결과와 배설성 요로 조영술을 통해 신우신염과 편측성 뇨관 완전폐색증으로 진단하였다. 신장절제술을 위한 개복술시 후복막강에 풍선형의 구조물을 발견하였다. 구조물로부터 채취한 시료의 세포검사와 배양검사결과 다수의 퇴행성 호중구와 탐식된 구균을 관찰하였다. 결론적으로 뇨관폐색과 방광결석을 동반한 Staphylococcus intermedius에 의한 복막후농양으로 최종 진단하였고 우측신장의 절제를 실시하여 치료하였다.
