What is Calyceal distention?

Calyces are the cavity or conduit that collects the urine from the kidney pyramids and funnels the urine into the ureter (the tube running from the kidney to the bladder). If this conduit or cavity becomes enlarged and ballooned with urine, possibly because of blockage of urine flow, this leads to calyceal dilatation.

What are minor calyces?

A minor calyx surrounds the renal papillae of each pyramid and collects urine from that pyramid. From the major calyces, the urine flows into the renal pelvis; and from there, it flows into the ureter. Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla).

What is dilation of the calyces and renal pelvis termed?

Hydronephrosis or urinary tract dilation refers to dilation of the pelvis and calyces of the kidney where urine is collected. Pictured left to right: Normal appearance of the renal pelvis, followed by increasing severity of hydronephrosis.

Is mild hydronephrosis serious?

Where is the minor calyx?

The minor calyces surround the apex of the renal pyramids. Urine formed in the kidney passes through a renal papilla at the apex into the minor calyx; two or three minor calyces converge to form a major calyx, through which urine passes before continuing through the renal pelvis into the ureter.

How many minor calyces are there?

structure of human kidney 12 smaller cuplike cavities, the minor calyxes, into which the renal papillae project. The renal pelvis serves as the initial reservoir for urine, which flows into the sinus through the urinary collecting tubules, small tubes that open into the sinus at the papillae.

What is mild dilation of renal pelvis?

Renal pelvis dilatation (or hydronephrosis) is a widening of the renal pelvis and is a common finding on ultrasound scans (USS) performed during pregnancy. Often it is temporary and not associated with any problems in the kidney or ureter. In this situation, there is no risk for your child’s future health.

What is mild Calyceal dilatation?

What is the function of the renal pelvis?

The renal pelvis (or, more rarely, the renal infundibulum) forms part of the pelvicalyceal system of the kidney and is the connection between the calyces and the ureter.
