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.
Segmental hypoplasia or Ask-Upmark kidney is a rare renal disease where a part of the kidney has undergone hypoplasia. The number of renal lobes is reduced, and the kidney size is less than two standard deviations from the average, with the weight often being over 50g in adults and 12–25g in children.

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.
