Herein, we report two rare cases of renal infection. The first case was renal subcapsular urine reflux in a 8-month-old girl with recurrent urinary tract infection and the second was subcapsular abscess in a 14-year-old girl with diabetes, who was successfully treated with percutaneous drainage. It has been suggested that renal subcapsular abscesses could be caused by the direct reflux of urine into the subcapsular space, rather than spread of infection from an existing parenchymal lesion, and that complete recovery can be achieved if percutaneous drainage is performed in a timely manner. We propose primary subcapsular reflux, in which urine directly refluxes upwards into the subcapsular space of the kidney, as one of the mechanisms for development of renal subcapsular abscesses.

A 12-year-old intact female Pomeranian dog was presented with vulvar discharge, lethargy, polyuria, and polydipsia. A complete blood count revealed leukocytosis and anemia. The serum biochemical analyses showed elevated serum alkaline phosphatase activity and blood urea nitrogen. Survey abdominal radiography revealed an enlarged left kidney. Abdominal ultrasonography identified multiple rounded hypoechoic subcapsular lesions in the left kidney. The bilateral uterine horn was enlarged, and contained echogenic fluid. Percutaneous ultrasonographic-guided aspiration of the renal subcapsular lesions was performed on the left kidney. Cytological examination revealed bacterial cocci, degenerated neutrophils, and suppurative inflammation. Bacterial culture produced growth of Escherchia coli. Left nephrectomy and ovariohysterectomy were performed. Dilated uterine fluid was also evaluated for bacterial culture, and showed growth of E. coli. Urine was examined by bacterial culture, and showed negative results. The treatment consisted of antibiotic therapy according to the antibiotic sensitivity test. Based on these findings, the diagnosis was renal subcapsular abscess associated with pyometra. This study suggests that pyometra should be considered as the cause of renal abscess.

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.
