The renal calyces are chambers of the kidney through which urine passes. 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.
Function
Peristalsis of the smooth muscle originating in pace-maker cells originating in the walls of the calyces propels urine through the renal pelvis and ureters to the bladder.
Clinical significance
Example of a "staghorn" kidney stone projecting into the renal calyces
A "Staghorn calculi" is a kidney stone that may extend into the renal calyces.
A renal diverticulum is diverticulum of renal calyces.[1][2]
