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.
The right kidney is often found more caudally and is slimmer than the left kidney, which may have a so-called dromedary hump due to its proximity to the spleen. The kidney is surrounded by a capsule separating the kidney from the echogenic perirenal fat, which is seen as a thin linear structure.
The renal calyces (sg. calyx) are conduits in the kidney through which urine passes. The minor calyces form a cup-shaped drain around the apex of the renal pyramids.Urine formed in the kidney passes through a renal papilla at the apex into the minor calyx; four or five minor calyces converge to form a major calyx through which urine passes into the renal pelvis (which in turn drains urine out ...
Kidneys: Right and left kidneys measure 11.5 cm and 12 cm in length respectively. No hydronephrosis. Small left lower pole kidney cyst. Ascites: None. Aorta: Visualized portions normal in caliber, 16 x 15 mm. IVC: Normal. IMPRESSION: Normal abdominal ultrasound.
Medullary cystic kidney disease (MCKD) is an autosomal dominant kidney disorder characterized by tubulointerstitial sclerosis leading to end-stage renal disease.Because the presence of cysts is neither an early nor a typical diagnostic feature of the disease, and because at least four different gene mutations may give rise to the condition, the name autosomal dominant tubulointerstitial kidney ...
Cystic kidney disease includes various conditions related to the formation of cysts in one or both kidneys. The most common subset is polycystic kidney disease (PKD), which is a genetic anomaly with two subsets, autosomal recessive polycystic kidney disease (ARPKD) and autosomal dominant polycystic kidney disease (ADPKD).
The enlargement of the kidney can be related to the degree of cyst formation. The cysts which come from the Bowmans space can also cause the kidneys to appear asymmetrical or misshapen. Cysts can cause injury by destroying nearby renal tissue [10] Familial GCKD can have enlarged or normal size kidneys. [6]
[10] [11] [12] The left kidney is approximately at the vertebral level T12 to L3, [13] and the right is slightly lower. The right kidney sits just below the diaphragm and posterior to the liver. The left kidney sits below the diaphragm and posterior to the spleen. On top of each kidney is an adrenal gland.
