Acute flank pain from urolithiasis is the most common condition in people visiting emergency rooms. This study is to evaluate the usefulness of color Doppler in detecting ureteral stones in patients without hydronephrosis. We performed ultrasonography and retrospective analysis on 161 patients who were suspected of urinary stones through plain radiography of the kidney, ureter, and bladder examination or urine tests that showed positive signs of hematuria. In ultrasonography, a total of 154 (95.6%) cases from the 161 patients were diagnosed with ureteral stones. In color Doppler, ureteral stones with twinkling artifact (TA) in the absence of hydronephrosis was shown in 18 (85.7%) cases of the 21 patients(p<0.001). The use of color Doppler has a high diagnostic efficacy for the detection of indistinguishable stones, non-dilatational ureteral stones, and middle ureter stones.

The purpose of this study was to investigate the association of twinkling artifacts according to the types of urinary stones in color Doppler ultrasound. For two types of urinary stones with different colors, the degree of occurrence of color Doppler twinkling artifact in water tank was analyzed, and the surface condition and composition of the stones were analyzed. The composition of Calcium and phosphorus were the most frequent components in white and brown stones excluding carbon and oxygen. Twinkling artifacts of color Doppler appear stronger in brown stone. The higher the phosphorus content of the stones, the shorter the twinkling artifact appears, so it is possible to predict the main composition of stones.

Nephrolithiasis is the most common disorder of the urinary tract in hospitalized patients, more frequently increased in 30~50 years of age, more common in males than in females, prior right stone to left side, and than upper ureteral stone is found in cultural country, while lower ureteral stone is increased in uncultural country. Stone components are classified as calcium oxalate, calcium phosphate, magnesium ammonium phosphate, uric acid, cystine, and their mixed stone, respectively. According to the pathophysiology of urinary stones, supersaturation/crystalization of inorganic salt concentration in urine, organic matrix, inhibitor deficiency, and epitaxy theory could be based on the stone formation. Not only hypercalciuria, hyperparathyroidism, hyperoxaluria, hyperuricosuria, and cystinuria, but also renal tubular acidosis, hypervitaminosis D, and peptic ulcer, are significantly associated with nephrolithiasis. In this study upper ureteral stone component were analyzed with chemical analysis, infrared spectrum, and image analyzer from K43 patient wit erosive gastritis. As the results, mixed stone of calcium oxalate dihydrate and calcium phosphate apatite was identified, the values of clinical test in blood and urine maintained normal revels. The relapsing urinary stone from K43 have no correlation between factors for stone formation reported early, also have no evidence for risk from erosive gastritis.

A 10-year-old intact female Miniature Schnauzer dog was referred with the primary complaint of persistent anorexia, remittent fever, vomiting and abdominal pain. Hemogram suggested a chronic inflammatory disease. Serum biochemistry showed moderate hepatobiliary cellular damage with severe cholestasis. Abdominal radiography and ultrasonography revealed hepatomegaly, choleliths and sludges in gall bladder and small stones in urinary bladder. Based on diagnostic findings, the case was diagnosed as cholelithiasis complicated with biliary sludge and urolithiais. Using cholecystectomy and cystectomy, choleliths and uroliths were removed from gall bladder and urinary bladder, respectively. The clinical condition was dramatically improved after surgery.

Hypertensive encephalopathy is an acute neurologic syndrome that occurs in association with abrupt and marked elevation of blood pressure and is characterized by headache, vomiting, seizure, visual disturbances and altered mental status. Hypertensive encephalopathy is most commonly associated with renal disease in children, including acute glomerulonephritis, reno-vascular hypertension, and end-stage renal disease. Hypertensive encephalopathy associated with nephrolithiasis has not been reported. We have experienced a 10-year-old boy with hypertensive encephalopathy associated with ureteral stone.

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.

Renal failure syndrome in wild mammals is infrequently reported. Muskrat (Ondatra zibethicus) is a medium-sized rodent known to carry many diseases but rarely exhibiting renal failure. A six-month old female muskrat was submitted to our laboratory for pathological diagnosis, and necropsy revealed severe renal damage with sand-like lithiasis in the ureter, renal calculi, and hydronephrosis. All major organs, including the cerebrum, also showed systemic hemorrhage and calcification which may have been due to uremia induced by renal failure. Histopathologically, necrosis and microcalcification were detected in the renal cortex and the medulla, especially in the proximal convoluted tubules and collecting ducts of the kidney. Significant hyalinization of the glomeruli was also observed, and this suggested chronic nephritis. These findings would support mycotoxic effects, particularly on the kidney. Moreover, infiltration of neutrophils and mononuclear cells was observed in the lung and of plasma cells in the spleen. The definitive cause of the toxic effects in this case of muskrat renal failure could be attributed to contaminated food.

The purpose of this study is to provide basic data for effective management and prevention of chronic diseases and secondary complications as elderly spinal cord injuries(SCI). The subjects were 200 spinal cord injuries admitted to S hospital from April, 2013 to April, 2018. We investigated the occurrence of chronic diseases and secondary complication through medical records. The results showed that SCI were affected chronic diseases and secondary complications over 50years. The prevalence of chronic diseases and secondary complications over 50 years of age had the odds ratio 11.8 times higher in hypertension and 6.7 times diabetes mellitus. Secondary complications had the odds ratio Osteoporosis 7.5 times, Pneumonia 5.2 times, and central pain 0.4 times. We suggest that continuous management and service of chronic diseases and secondary complications of elderly SCI are necessary. It will be necessary to expand the target population and to study various characteristics including.

Purpose: The aim of this study was to evaluate the clinical usefulness of ultrasound examination of children performed by a pediatrician. Methods: One thousand children who presented with symptoms of a gastrointestinal disorder and underwent abdominal ultrasound evaluation in the Department of Pediatrics, between January 2003 and June 2006, were included in this study. We analyzed the patient's medical records and ultrasound results retrospectively. Results: Among the 1,000 patients, 58.4% were male and 41.6% were female. The mean age of the patients was $4.7{\pm}4.0$ years. The main reasons for ultrasound were abdominal pain (43.9%), vomiting (17.3%), elevated liver enzymes (11.8%), and jaundice (9.8%). Abnormal ultrasound findings were present in 57.9% of cases. The major abnormal findings were mesenteric lymphadenitis (29.2%), fatty liver (12.1%), hepatitis (6.4%), hepatosplenomegaly (6.2%), and acute appendicitis (4.8%). The time interval between the initial medical evaluation and the ultrasound evaluation was within 24 hours in most cases (78.5%). The main findings in children with abdominal pain were mesenteric lymphadenitis (32.6%), fatty liver (5.9%), intussusception (2.7%), and acute appendicitis (2.7%). The main findings in children with vomiting were mesenteric lymphadenitis (12.7%), hypertrophic pyloric stenosis (10.4%), and acute appendicitis (3.5%). The major ultrasound findings in children with urinary tract diseases were hydronephrosis (45.4%), urolithiasis (21.5%) and cystic renal disease (18.1%). Conclusion: Ultrasound examination played an important role as a non-invasive and prompt screening examination for detection of abdominal diseases. Ultrasound was an important tool for pediatricians to determine timely information for patient management.
