[1] Figure 18. Renal stone located at the pyeloureteric junction with accompanying hydronephrosis. [1] With US, larger stones (>5–7 mm) within the kidney, i.e., in the calyces, the pelvis and the pyeloureteric junction, can be differentiated, especially in the cases with accompanying hydronephrosis (Figure 18 and Figure 19).

The signs and symptoms of hydronephrosis depend upon whether the obstruction is acute or chronic, partial or complete, unilateral or bilateral. Hydronephrosis that occurs acutely with sudden onset (as caused by a kidney stone) can cause intense pain in the flank area (between the hips and ribs) known as a renal colic. Historically, this type of ...
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 renal pelvis is the location of several kinds of kidney cancer and is affected by infection in pyelonephritis. [citation needed] A large "staghorn" kidney stone may block all or part of the renal pelvis. The size of the renal pelvis plays a major role in the grading of hydronephrosis.
This includes homogenous, high-attenuation (60–70 Hounsfield units [3]) lesions less than 3 cm with sharp margins but without enhancement. Hyperdense cysts must be exophytic with at least 75 percent of its wall outside the kidney to allow for appropriate assessment of margins, otherwise they are categorized as IIF. [6]
This stage accounts for 17% of kidney cancers and 69% of people are expected to live 5 years with this progression of kidney cancer. •Stage 4, the kidney tumour has spread to a distant organ or lymph node. 16% of kidney cancers are progressed to this stage and of those people, 12% of them are expected to live 5 years.

Human gallstones, all removed from one patient. Grid scale 1 mm. Calculi in the inner ear are called otoliths; Calculi in the urinary system are called urinary calculi and include kidney stones (also called renal calculi or nephroliths) and bladder stones (also called vesical calculi or cystoliths). They can have any of several compositions ...
