STRUCTURE AND POSITION
- Renal Pelvis is funneled shape and dilated. Larger end of the funnel is inside the kidneys.
- It is present on medial concave side of kidneys on both sides.
- Renal Pelvis gives off cup like projections inside kidney each of which are attached to renal papilla (Calyx, plural : Calyces)
- Epithelium of Renal Pelvis is made up of elastic expandable cells (Transitional Epithelium) and it has loose connective tissue beneath it.
Renal Pelvis functions like a funnel and collects urine formed in kidneys through its calyces. Then it funnels all of it into ureters to be transported into Urinary Bladder. It also produces rhythmic contractions which help in transfer of urine towards ureters (Peristalsis).
Renal Pelvis is prone to develop several forms of cancer.
