Renal Sinus receives urine from the calyces.
Renal Pelvis
renal sinus
It is a kidney stone present in any of the calyxes of the kidney.

There are an equal number of pyramids per kidney as there are minor calyces. ie If there are 8-18 minor calyces per kidney, there will be a matching number of pyramids (8-18). Therefore, if a cat has 12 minor calyces, there will be 12 pyramids as well in that kidney.
The renal pelvis (middle part of the kidney) is the main cavity leading into the ureter, which drains away urine. There is only one renal pelvis for each kidney. The renal pelvis itself is shaped by projections into it called major calyces. The cavities created by these projections are still part of, and in continuity with, the renal pelvis.

The cavity of the kidney that receives the urine before it is passed into the ureter.
The individual units of the kidney, called nephrons, produce urine and empty into structures called collecting ducts. Many nephrons empty into a single collecting duct. Similarly, many collecting ducts empty into a minor calyx. Minor calyces empty into a major calyx, and the major calyces empty into the singular renal pelvis (each kidney has a single pelvis). The renal pelvis empties into the ureter.
Mild dilatation of the collecting system of the kidney-- calyces and renal pelvis.

2 to 3 in each kidney according to dr qasim dawiri slides :)
A left kidney with mild pelvocaliectasis means that the kidney has a dilated renal pelvis as well as calyces. This can be see through an ultrasound and it curable.
