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.

In malaria, splenic rupture is a serious complication potentially leading to death. Subcapsular hemorrhage of spleen is thought to be an impending sign of splenic rupture; however, the characteristics of subcapsular hemorrhage are not well known. We report 3 cases of subcapsular hemorrhage of the spleen in vivax malaria, with varying degrees of severity. Case 1 showed subcapsular hemorrhage without splenic rupture, was treated by antimalarial drug without any procedure. The healing process of the patient's spleen was monitored through 6 computed tomography follow-up examinations, over 118 days. Case 2 presented subcapsular hemorrhage with splenic rupture, treated only with an antimalarial drug. Case 3 showed subcapsular hemorrhage with splenic rupture and hypotension, treated using splenic artery embolization. They all recovered from subcapsular hemorrhage without any other complications. These 3 cases reveal the process of subcapsular hemorrhage leading to rupture and a potentially fatal outcome. The treatment plan of subcapsular hemorrhage should be determined carefully considering the vital signs, changes in hemoglobin, and bleeding tendency.

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.

Vascular complications after percutaneous angiography include hematoma, pseudoaneurysm, arteriovenous fistula, thromboembolism, arterial laceration and infection. Hematomas may occur in the groin, thigh, retroperitoneal, intraperitoneal, or abdominal wall. A 54-year-old female underwent percutaneous transfemoral angiography for the evaluation of cerebral aneurysm. Renal subcapsular hematoma developed 3 hours after the procedure. Renal subcapsular hematoma after percutaneous angiography is very rare. We investigated the possible causes of renal subcapsular hematoma. To avoid this rare complication, we need to perform guide-wire passage carefully from the beginning of the procedure under full visual monitoring.

Page kidney refers to the phenomenon of hypertension secondary to long-standing compression of renal parenchyma caused by renal subcapsular collection. The most common cause of renal subcapsular collection is a hematoma which usually occurs after a history of blunt trauma. A 42-year-old female patient who received botulinum toxin injection in her back during chiropractic care was admitted to the emergency room with sudden bilateral flank pain and hypertension. The computed tomography (CT) images demonstrated the presence of bilateral subcapsular renal hematoma. The patient was treated conservatively and recovered well. The follow up CT images showed markedly resolved bilateral hematoma.

신생아의 피막하 간 혈종은 다양한 원인에 의해서 유발되는데 대부분은 출혈의 양이 적어 임상적으로 발견되기 보다는 부검시 발견되는 경우가 많다. 그러나 출혈의 양이 많아 혈종을 싸고 있는 피막이 파열되고 잇따른 출혈이 발생할 경우에는 창백, 혈관 허탈, 빈혈, 복부팽만, 저산소증, 산혈증 등의 증상을 보이므로 조기에 의심하여 정확한 진단을 내리고 적절한 수술적 치료를 실시하지 않으면 사망률이 높다. 저자들은 태변 흡입후 신생아 가사 소견을 보여 심폐소생술을 실시한 신생아에서 출생후 7일에 발현된 대량 피막하 간 혈종 파열 1례를 경험하였기에 보고하는 바이다.

노인성 백내장의 세 가지 형태학이 굴절이상에 미치는 영향에 관하여 연구하기 위해 세 가지 형태의 백내장 특성에 따른 구면 굴절력과 원주 굴절력의 변화를 백내장의 형태적인 위치에서 나타내었고 또한 백내장 수술 전후의 안압이 굴절이상에 어떠한 영향을 주는가에 대하여 연구하였다. 등가 구면 굴절력에서 핵 백내장은 근시성 전환, 피질 백내장은 원시성 전환을 보였고 낭 백내장은 양쪽의 전환 폭이 적은 것으로 나타났다. 수정체 내 백액내장의 해부학적 위치를 확인하기 위해 광학단면(세극등)을 이용하여 관찰하였고 굴절이상을 측정하기 위해 타각적, 그리고 자각적 방법을 사용하여 등가 구면 굴절력으로 나타내었다. 안압 측정은 수술전과 수술 후 인공수정체가 삽입된 일주일 뒤에 다사 각각의 상태에서 안압을 자동 안압계를 사용하여 측정하였다. 원주 굴절력의 변화는, 일반적으로 나이가 증가함에 따라 안축의 길이가 감소하는 경향을 보였지만, 백내장의 진행으로 안압이 높아져 안축의 길이가 증가하게되고 그 영향으로 직난시에서 도난시로의 전환에 영향을 주기도 하고 또한 이것이 안압으로 인해 더욱 증가하기도 함을 알 수 있었다.

Objective: To evaluate the impact of energy and access methods on extrahepatic tumor spreading and the ablation zone in an ex vivo subcapsular tumor mimic model with a risk of extrahepatic tumor spreading. Materials and Methods: Forty-two tumor-mimics were created in bovine liver blocks by injecting a mixture of iodine contrast material just below the liver capsule. Radiofrequency (RF) ablations were performed using an electrode placed parallel or perpendicular to hepatic surface through the tumor mimic with low- and high-power protocols (groups 1 and 2, respectively). Computed tomography (CT) scans were performed before and after ablation. The presence of contrast leak on the hepatic surface on CT, size of ablation zone, and timing of the first roll-off and popping sound were compared between the groups. Results: With parallel access, one contrast leak in group 1 (1/10, 10%) and nine in group 2 (9/10, 90%) (p < 0.001) were identified on post-ablation CT. With perpendicular access, six contrast leaks were identified in each group (6/11, 54.5%). The first roll-off and popping sound were significantly delayed in group 1 irrespective of the access method (p = 0.002). No statistical difference in the size of the ablation zone of the liver specimen was observed between the two groups (p = 0.247). Conclusion: Low-power RF ablation with parallel access is proposed to be effective and safe from extrahepatic tumor spreading in RF ablation of a solid hepatic tumor in the subcapsular location. Perpendicular placement of an electrode to the capsule is associated with a risk of extrahepatic tumor spreading regardless of the power applied.

SCH는 주로 낭종, 출혈 경향, 암, 혈관질환에 의해 발생하나 드물게 감염에 의해 발생할 수 있다. 본 증례는 기저질환으로 조절되지 않는 당뇨, 음주력이 있는 환자에서 급성 신우신염의 합병증으로 양측 SCH가 발생한 국내 첫 보고이다. CT를 통하여 양측 SCH를 진단하였고 원인 감별을 위한 검사 진행 후 감염이 원인임을 확인하였다. 항생제 치료와 더불어 패혈증, 파종성 혈관 내 응고에 대해 신대체 요법 진행 후 신기능 및 감염 소견이 호전되어 중단하였고 이후 양측 PCD를 통하여 혈성, 농양 배액을 30일간 유지한 뒤 제거 후 퇴원하였다. 본 사례는 양측 SCH의 드문 원인으로서 급성 신우신염이 가능함을 확인한 국내 첫 사례 보고라는 점에서 의의가 있다.

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.
