Renal ultrasound (US) is a common examination, which has been performed for decades. Using B-mode imaging, assessment of renal anatomy is easily performed, and US is often used as image guidance for renal interventions. Furthermore, novel applications in renal US have been introduced with contrast-enhanced ultrasound (CEUS), elastography and ...
The image generated by the ultrasound can help diagnose renal cell carcinoma based on the differences of sound reflections on the surface of organs and the abnormal tissue masses. Essentially, ultrasound tests can determine whether the composition of the kidney mass is mainly solid or filled with fluid. [49]
The incidence rate of kidney tumours is greater in men than in women. [11] The incidence of kidney tumours is more greatly distributed in North America and Europe than in Asia and South America. The incidence of small renal tumours (masses under 4 cm long) has been increasing since the 1980s.

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.
Gross appearance of a renal oncocytoma (left of image) and a slice of a normal kidney (right of image). Note the rounded contour, the mahogany colour and the central scar. In gross appearance, the tumors are tan or mahogany brown, well circumscribed and contain a central scar. They may achieve a large size (up to 12 cm in diameter).
Hybrid oncocytoma/chromophobe carcinoma, found in 50% of cases, [8] is the most commonly found cancer, followed by chromophobe renal carcinoma, clear cell renal carcinoma, renal oncocytoma, and papillary renal cell carcinoma. [5] [8] People over 40 years old and men are more likely to develop kidney tumors, which are diagnosed at a median age ...
Ultrasound involves a probe that is placed near a structure and uses the transmission of ultrasound waves through a structure to produce images, after computer processing. [1] Ultrasound of the urinary tract is performed by a probe placed on the abdominal wall, called a transducer. [1] This occurs while a person is lying down. [1]
