The renal pelvis
is the funnel-like dilated proximal part of the ureter
in the kidney
It is the point of convergence of two or three major calyces. Each renal papilla is surrounded by a branch of the renal pelvis called a calyx.
The major function of the renal pelvis is to act as a funnel for urine flowing to the ureter.
