Renal Pelvis

Renal pelvis highlighted in green

The renal pelvis is the proximal dilated aspect of the ureter in the kidney. It functions to funnel urine into the ureters.

Urine empties from the renal papilla into the minor calyces, which in turn drain into the major calyces, and then into the renal pelvis.
