A 10-year-old, female spayed mixed-breed dog with a history of vomiting and anorexia was examined. Abnormal findings of comlete blood count and serum chemistry included polycythemia, thrombocytopenia, hyper-globulinemia and hypoalbuminemia. Abdominal radiographs revealed severe unilateral renomegaly, and ultrasonography showed a left-sided renal mass. During the operation, left kidney was resected. Cytologial and histopathological examinations revealed neoplastic lymphoid proliferation with high mitotic figures in renal mass. Immunohistochemistry revealed tumor cells were CD3-positive and CD79${\alpha}$-negative, consistent with T-cell lineage. The renal mass of this case was diagnosed as renal T cell lymphosarcoma.

A two-year-old spayed female Persian cat demonstrated weight loss, anorexia, and vomiting for one week. Hematologic findings suggested chronic renal failure. Radiography and ultrasonography revealed severe bilateral renomegaly with hypoechoic nodules and subcapsular hypoechoic rim. Fine needle aspiration of the kidney revealed malignant lymphoma. The cat received in-hospital treatment for chronic renal failure for seven days, followed by chemotherapy (cyclophosphamide, vincristine, and prednisolone). The cat tolerated chemotherapy well and chronic kidney disease was alleviated. However, complete remission was not achieved. After 93 days of treatment, the cat exhibited anisocoria and mental dullness. Brain magnetic resonance imaging revealed hypertrophy and enhancement of cranial nerves. Chemotherapy was replaced with lomustine (10 mg orally), and two weeks later, cytosine arabinoside (50 mg/㎡ subcutaneously), twice daily for consecutive days. Five days after substitution chemotherapy, the patient showed anemia due to severe intestinal bleeding and died. Post-mortem examination and histopathologic analysis confirmed renal T-cell lymphoma with metastasis to the central nervous system, colon, and nasal cavity. Survival time was 117 days after the diagnosis of renal lymphoma.

A 13-yr-old Shih tzu was referred for surgical management of right-sided cranial abdominal mass, which corresponded to large, cavitated renal mass on ultrasonography, and was suspected to represent neoplasia. Intraoperative impression smear cytology (ISC) of the renal mass wall was consistent with benign renal cyst (RC), without evidence of neoplasia or infection. Deroofing and omentalisation were performed and histopathology was consistent with benign RC. Chronic kidney disease was diagnosed 4 mon postoperatively, however, the dog was asymptomatic, without cyst reoccurrence. Intraoperative ISC is an expedient and inexpensive diagnostic technique that can guide most appropriate treatment in dogs with large RCs.

Aim: The aim of the present study was to evaluate retrospectively histopathologically-diagnosed lesions that were detected in the kidney after radical nephrectomy for a preoperative diagnosis of kidney cancer. Methods: The medical records of 83 patients (51 male, 32 female) were included. Preoperative staging was accomplished by various methods including physical examination, blood hemography and biochemistry, abdominal ultrasonography (US), chest x-ray, abdominal computed tomography (CT) and abdominal magnetic resonance imaging (MRI). Results: Totals of 70 patients underwent radical nephrectomy and 13 nephron sparing surgery. Of the 83 patients, 70 had malignant lesions (renal cell carcinoma, squamous cell carcinoma or other malignancies) 13 had a variety of benign lesions, the most frequently detected being oncoytoma (6), angiomyolipoma (3), xanthogranulamatous pyelonephritis (2), cortical cyst (1) and chronic pyelonephritic change (1). Conclusion: It was concluded that in spite of great technological developments regarding radiological imaging modalities such as US, CT and MRI, benign lesions might still be detected pathologically in patients who undergo radical nephrectomy with the preoperative diagnosis of renal cancer. But, all renal masses should be regarded as malignant and should be managed surgically otherwise proven benign.

Distal renal tubular acidosis (dRTA) is a rare renal tubular disorder characterized by normal anion gap metabolic acidosis, hypokalemia, and high urine pH. It can be inherited or acquired. In untreated pediatric patients with dRTA, rickets and growth retardation are common. We report the case of a 12-year-old Lao girl who presented with typical clinical features of dRTA with severe bone deformities that developed after a bed-ridden state due to a bicycle accident at the age of 8 years. Initial laboratory tests revealed metabolic acidosis with a normal anion gap, hypokalemia, and alkali urine. Renal ultrasonography revealed bilateral medullary nephrocalcinosis. Whole exome sequencing revealed no pathogenic mutations. After treatment with oral alkali, potassium, and vitamin D, she could walk and run. Later, she underwent corrective orthopedic surgeries for bony deformities. Thus, in pediatric dRTA patients, despite severe symptoms remaining untreated, accurate diagnosis and proper management can improve quality of life.

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.

Background: In solid organ transplantation patients, complications of cholelithiasis may run a fulminant course, resulting in high morbidity and mortality under immunosuppression and may even result in rejection. Here, we reviewed medical records of 66 patients in order to determine the outcome of management approach for asymptomatic gallstones in renal transplantation patients. Methods: We retrospectively reviewed clinical courses of 66 cases of renal transplantation performed between 2000 and 2012 at Kosin University Gospel Hospital. Results: Among 66 cases, eight had gallstones before transplantation. Three of these cases had undergone previous cholecystectomy for symptomatic gallstones, one had a simultaneous laparoscopic cholecystectomy and renal transplantation, and four were observed by regular abdominal ultrasonography. One patient was found to have cholangitis, and endoscopic retrograde biliary drainage was performed, resulting in alleviation of symptoms. Among 58 cases without preoperative gallstones, three developed gallstones after transplantation. One patient had cholecystitis, and the symptoms subsided after conservative treatment. Conclusions: For patients with asymptomatic gallstones who are awaiting renal transplantation, expectant management should be considered.
