Angiomyolipoma seen as a hyperechoic mass in the upper pole of an adult kidney on renal ultrasonography. Renal ultrasonography of a person with tuberous sclerosis and multiple angiomyolipomas in the kidney: Measurement of kidney length on the US image is illustrated by '+' and a dashed line. CT scan of a renal angiomyolipoma.
The kidney is surrounded by a capsule separating the kidney from the echogenic perirenal fat, which is seen as a thin linear structure. [1] The kidney is divided into parenchyma and renal sinus. The renal sinus is hyperechoic and is composed of calyces, the renal pelvis, fat and the major intrarenal vessels.
The first successful kidney transplant in central Ohio was performed at Children's in 1966, on an 11-year-old boy. Also in 1966, a new infant intensive care service (NICU) opened, specializing in the care of the seriously ill infants. It was operated independently of the regular intensive care unit (ICU). [17]
Ultrasound findings that indicate pyelonephritis are enlargement of the kidney, edema in the renal sinus or parenchyma, bleeding, loss of corticomedullary differentiation, abscess formation, or an areas of poor blood flow on doppler ultrasound. [21] However, ultrasound findings are seen in only 20–24% of people with pyelonephritis. [21]
A renal cyst is a fluid collection in or on the kidney. There are several types based on the Bosniak classification. There are several types based on the Bosniak classification. The majority are benign, simple cysts that can be monitored and not intervened upon.
Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
The correlation between the accessory nipples and renal abnormalities was first introduced by K. Mehes in 1979 in a study of 20 children with polythelia. In this study, eight out of the twenty children had kidney lesions, proving statistically significant data and concluded an association between supernumerary nipples and renal abnormalities.
Lesion Characterization: contrast-enhanced ultrasound plays a role in the differentiation between benign and malignant focal liver lesions. This differentiation relies on the observation [ 15 ] or processing [ 16 ] [ 17 ] of the dynamic vascular pattern in a lesion with respect to its surrounding tissue parenchyma .
