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.
