Ultrasonography observations were made of the kidneys of 21 dogs. Ultrasonography images obtained in transverse and longitudinal planes. A 3.5-MHz linear transducer was used. All examinations were peformed on dogs in dorsal recumbency under anesthesia. The right kidney was 3.2~3.8cm long, 1.7~3.5 cm wide and 1.0～1.9cm deep in 0～5 of body weight group, 3.6~4.6cm long, 2.4～3.6cm wide and 1.4～2.1cm deep in 5～10 of body weight group, and 4.6～6.4cm long, 3.3～4.2cm wide and 2.0~2.0cm deep in 10～15kg of body weight group(p< 0.01). Diameter of the parenchyma of the right kidney ranged between 0.4～0.9cm in 0～5kg group, 0.6～1.0cm in 5～l0kg group and 0.9-1.1cm in 10~15kg group(p<0.01). Diameter of the renal sinus of the right kidney ranged between 0.3～0.5cm in 0～5kg group, 0.4～0.7cm in 5～10kg group and 0.5～0.9cm in 10~ 15kg group(p< 0.01). Similar ultrasonic measurements were obtained for the left kidney. It was concluded that the ultrasonographic findings described in this study can be used as references for diagnosis of morphologic changes in e canine kidney.

A female 8-year-old Pug weighing 7.3 kg and a female 10-year-old Maltese dog weighing 3.5 kg showing anorexia and vomiting for a few weeks were referred to Veterinary Medical leaching Hospital, Seoul National University. Radiographic findings were an enlarged right kidney in a pug dog and a radiopaque material on the right ureteral region lateral to the third lumbar vertebrae with indefinite right kidney contour in a Maltese dog, repectively. Excretory urography performed in a Pug dog revealed a poor opacified enlarged right kidney with absent of pelvic recesses and pelvic dilation with proximal ureteral dilation on contralateral kidney. Ultrasonographic findings were enlarged kidney with dilated pelvis and echogenic sediment within the medulla in both dogs and especially an engorged proximal ureter and a thin rim of functional renal tissue remains in a Maltese dog. Those diagnostic findings indicated high possibility of pyelonephritis and these were confirmed by pathologic examination. Radiography and ultrasonography, although not giving final diagnosis for pyelonephritis, are useful for assessment and diagnosis of pyelonephritis.

A seven-year-old, castrated male, Korean domestic shorthair cat was referred because of a kidney abnormality. Radiography revealed left renal agenesis and right kidney enlargement. Ultrasonography and computed tomography (CT) showed amorphous calcified materials in a cyst-like lesion of the right kidney. In the excretory phase of the CT images, the lesion was opacified with contrast materials, indicating communication with the collecting system. Based on these findings, the cat was diagnosed with a calyceal diverticulum. A calyceal diverticulum may cause various clinical symptoms related to the urinary system. The excretory phase of CT is useful for diagnosing a calyceal diverticulum.

This study was performed to validate the procedure of transarterial embolization of the renal artery (TAE-RA) and sclerotherapy of renal pelvis using iohexol-ethanol solution in dogs with unilateral experimental hydronephrosis. Experimental hydronephrosis was induced by unilateral ureter ligation for 20 days in five Beagle dogs. Renal artery embolization with iohexol-ethanol solution was performed using selective catheterization technique in the hydronephrotic kidney and sclerotherapy was done by injection of the iohexol-ethanol solution through percutaneously placed pig-tail catheter. EKG, $SpO_2$ body temperature, pulse, and respiratory rate were within normal ranges during procedures. Average pure ethanol dose for renal artery embolization was $1.1\pm0.3ml/kg$. Renal artery embolization was confirmed by the detection of no blood flow signal at the interlobar and arcuate artery using color Doppler ultrasonography. There were no dogs expired after TAE-RA and sclerotherapy and no side effects associated with regurgitation of iohexol-ethanol solution. The value of BUN, creatinine, ALT, AST, Ca, P in five dogs were within normal range during the experiment period. Ultrasonographically, the mean longitudinal and transverse length and the depth of the embolized kidney significantly decreased at 28 days after TAE-RA. We may conclude that TAE-RA and sclerotherapy with iohexol-ethanol solution is an effective methods for the treatment of unilateral hydronephrosis in dogs.

A 13-year-old male Yorkshire terrier was Presented with Persistent weight loss anorexia and dark brown urine of 3-month duration. On physical examination, a firm oval mass was palpated at left renal region. In hematology and blood chemistry, neutrophilia, anemia, thrombocytopenia and elevation of ALKP were found. Abdominal radiography, ultrasonography and ultrasound-guided percutaneous pyelogram revealed masses originated from left kidney, mildly dilated renal Pelvis and intact ureter. Urinalysis showed hematuria and proteinuria. Because the state of dog became deteriorated during transfusion and the frail renal tumor was suspected to be the cause of inflammation and anemia, nephrectomy was performed. Renal masses, approximately $2{\times}3cm\;and\;5{\times}4cm$ respectively in size, was surrounded by swollen and congested mesentery and ascites. Metastatic lesion was not found in other organs. During recovery, the dog showed cardiopulmonary arrest and did not respond to critical care. Histologically the kidney was affected by necrotic and hemorrhagic change. This hemangiosarcoma most likely arose from the renal parenchyma resulting In diffuse lesions in the kidneys thought to be the cause of chronic anorexia and weight loss.

Sotos syndrome (SS, OMIM 117550) is characterized by prenatal and postnatal overgrowth with multiple congenital anomalies. However, there have been few cases of growth retardation caused by renal failure from infancy. We report a case of dysplasia of the bilateral kidneys with renal failure and poor postnatal growth. A 2-month-old boy visited the emergency room owing to poor oral intake and abdominal distension. He was born at the gestational age of 38 weeks with a birth weight of 4,180 g. After birth, he had feeding difficulty and abdominal distension. Upon physical examination, his height and weight were in less than the 3rd percentile, while his head circumference was in the 50th percentile on the growth curve. He also showed a broad and protruding forehead and high hairline. Blood laboratory tests showed severe azotemia; emergent hemodialysis was needed. Abdominal ultrasonography revealed bilateral renal dysplasia with multiple cysts and diffuse bladder wall thickening. A posterior urethral valve was suggested based on vesicoureterography and abdominal magnetic resonance findings. Results of a colon study to rule out congenital megacolon did not reveal any specific findings. The conventional karyotype of the patient was 46, XY. Array comparative genomic hybridization study revealed a chromosome 5q35 microdeletion including the NSD1 gene, based on which SS was diagnosed. We describe a case of SS presenting with end stage renal disease due to posterior urethral valve. The typical somatic overgrowth of SS in the postnatal period was not observed due to chronic renal failure that started in the neonatal period.

목적 : 산전 초음파의 도입으로 출생 이전에 수신증을 발견하는 경우가 점차로 증가하고 있다. 수신증의 대부분은 태아기나 영아를 거치는 동안 자연적으로 소실되는 생리적 수신증이지만 수술적교정을 요하는 병적 수신증과 감별을 요한다. 그러나 아직까지 현재의 기술로는 일정한 관찰 기간 없이 병적 수신증을 정확하게 진단 하기는 어렵다. 본 연구에서는 산전 초음파 검사상 수신증이 의심되는 태아에서 산후 수신증을 확진하고 산전과 산후의 여러 요소와의 연관성을 비교 분석하여 조기진단 및 조기치료를 통하여 수신증으로 인한 신손상 및 합병증을 예방하는데 도움을 주고자 본 연구를 시행하였다. 방법 : 1985년 11월부터 1997년 9월까지 11년 10개월간 연세대학교 신촌 및 영동 세브란스병원에서 정기산부인과 초음파 검사를 실시하여 출생후까지 태아 수신증이 지속되었던 환아 65명 및 타 병원에서 산전 수신증이 의심되어 본원으로 전원되어 출생후까지 수신증이 지속되었던 환아 10명을 대상으로 하였다. 출생후 추적 초음파 검사 및 필요에 따라 이뇨성 신기능도, 경정맥 요로촬영, 배뇨성 요도방광찰영, DMSA 신주사를 시행하여 수신증을 확진하였고 산전, 산후 여러 요소와의 관계를 후향적으로 분석하였다. 결과 : 총 환아 75명중 남아가 56명, 여아가 19명이었으며 양측성이 30명, 일측성이 45명이었고 총 105신단위중 38%에서 수술이 필요했다. 원인별로 요관 신우 접합부 폐쇄가 52%로 가장 많았으며 다발성 낭성 이형성신(10%), 요관방광 접합부 폐쇄(10%), 요관방광역류, 중복요관, 요관류 순이었고 원인을 찾을수 없는 경우도 25%였다. 신배확장군, 요로감염군, 수신증의 정도가 높은군에서 통계적으로 의의있게 수술을 더 많이 시행받았다. 또한 산전 초음파검사상 22mm 이상인 경우, 산후 1개월내 첫 초음파검사상 17mm이상인 경우에 80%이상에서 수술을 시행받았다. 결;론 : 산전 검사상 신배확장을 보인 경우, 산후에 요로감염을 보인 경우, 수신증의 정도가 점점 증가하는 경우 병적 수신증일 가능성이 더 크며, 산전 초음파검사상 신우직경이 22mm이상, 산후 1개월이내의 첫 초음파검사상 17 mm 이상인 경우에는 병적인 수신증인 경우가 많으므로 조기에 수술을 고려해야 할 것으로 사료된다.
