PURPOSE: To evaluate the prevalance of morphological variation of the kidney secondary to junctional parenchyma, as well as to analyze the ultrasonographic features of junctional parenchyma. MATERIALS AND METHODS: Two hundred and eighty two kidneys of 141 patient without clinical or radiologic evidence of renal disease were prospectively analysed using ultrasound. In all patients, ultrasonograms were obtained in sagittal, coronal and transaxial planes. The kidney was considered to have morphological variation if the ulrasonogram demonstrated junctional parenchymal defect or line ; those showing such variation were classified as one of three types :continuous, discontinuous, or junctional parenchymal line or defect without junctional parenchyma. The prevalance and ultrasonographic features of the kidneys were evaluated. RESULTS: Morphological variation was noted in 71 cases(25%). the continuous type accounted for 54% of these, the discontinuous type for 38%, and junctional parenchymal defect or line without junctional parenchyma for 8%. In all cases, junctional parenchyma was located approximately at the junction of the upper and middle third of the kidny, and had the same echogenecity as the renal cortex. CONCLUSION: An understanding of the morphological variation of the kidney resulting from junctional renal parenchyma would be helpful in differentiating pseudo tumor from true renal neoplasm.

Background:The dimension and function of kidney have close relationship. In the developing countries, the index on kidney dimension of children has rather fully studied. In Viet Nam, most of studies only conducted on adults. Objectives:This study aims to determine the ultrasound kidney dimension and the correlation of kidney length and age, weight and height of children aged from 6 to 8 years old. Subjects and method: The data was obtained from a prospective study on 180 normal children at age from 6 to 8 years. Each kidney was measured length, width , thickness, and parenchymal thickness, and the mean values were recorded. The relationship of kidney length with age, body weight, body height were also taken. Results: Kidney dimension was increased by age. The average ultrasound kidney dimension:+ Right kidney: At 6 years old: Boy: length: 72.8\xb14; width: 31.2\xb13 ; thickness: 33.9\xb12 ; Girl: length: 69.8\xb15; width: 30.4\xb12 ; thickness: 32.7\xb12. At 7 years old: Boy: length: 75.2\xb14; width: 31.9\xb12; thickness: 33.8\xb13; Girl: length: 75.8\xb15; width: 32.0\xb12; thickness: 32.9\xb14; + Left kidney: At 6 years old: Boy: length: 73.9\xb15; width: 33.7\xb13 ; thickness: 34.9\xb12 ; Girl: length: 71.1\xb14; width: 32.4\xb13 ; thickness: 32.4\xb16. At 7 years old: Boy: length: 77.7\xb13; width: 33.8\xb13 ; thickness:34.7\xb12; Girl: length: 76.9\xb17; width: 32.0\xb12; thickness: 33,9\xb15; The kidney length, kidney weight, kidney volume of boys were bigger than girls, and the difference was significant (p<0.05). Conclusion: The kidney length correlated strongly and positively with body weight, body height and age.

137 patients with blunt renal trauma were examined by the sonography which can classify exactly 86.2% of renal injuries. Signs of the deformed kidney, of renal contour discontinuation and of the retroperitoneal hematoma were significantly for classification of renal injuries

Determine ultrasonic features of renal trauma patients at Viet Tiep Hospital, Hai Phong city. Subject: 21 renal trauma patients (14 males and 7 females) with mean age 30.71±13.85 years treated from April 2001 to April 2002. Method: Use ultrasound examination, classify renal trauma. Results: ultrasound examination is 1st choice of imaging diagnosis because it is fast, noninvasive, and easy using in emergency situations. Among 21 renal trauma patients (13 patients in grade I, 2 patients in grade II, and 6 patients in grade III), ultrasonic findings were contusion and parenchymal hematoma (71.42%), rupture (swallow or deep) (28.57%), perirenal hematoma (23.81%). In cases of grade III renal trauma, ultrasound imagines showed shallow or deep rupture (5 of 6 cases) and perirenal hematoma (4 of 6 cases)

The development of a perirenal hematoma is rare and primarily the result of trauma, malignancy, or a connective tissue disease. Infrequently, a continuous or even mild trauma can cause a perirenal hematoma. Here, we report a case involving the development of a perirenal hematoma after excessive hula-hooping in the absence of a major trauma history.
