Renal pelvis. The renal pelvis or pyelum is the funnel-like dilated proximal part of the ureter in the kidney. In humans, the renal pelvis 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 renal papilla has collecting ducts, small openings that allow urine to pass through. From the collecting ducts, the urine progresses to the renal pelvis, a widened area of the kidney, and exits through the ureter. The urine passes through the ureters to the urinary bladder.idneys: location and structure. The kidney is a reddish bean-shaped organ in the lower back near the twelfth rib.
