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 kidneys are surrounded by a fibrous, transparent renal capsule; a fatty adipose capsule that cushions the organ; and an outer fibrous renal fascia that anchors the kidney to surrounding structures. There are three distinct regions of the kidney: the cortex, the medulla, and the renal pelvis.ephrons are the structural and functional units of the kidneys that carry out processes that form urine. Each nephron consists of a renal corpuscle composed of a tuft of capillaries (the glomerulus), surrounded by a glomerular capsule (Bowman s capsule) and a renal tubule.
