Anatomical terminology |
The renal pelvis or pelvis of the kidney is the funnel-like dilated part of the ureter in the kidney. It is formed by the convergence of the major calyces, acting as a funnel for urine flowing from the major calyces to the ureter. It has a mucous membrane and is covered with transitional epithelium and an underlying lamina propria of loose-to-dense connective tissue.
The renal pelvis is situated within the renal sinus alongside the other structures of the renal sinus.[1]
Clinical significance
The renal pelvis is the location of several kinds of
staghorn
" kidney stone may block all or part of the renal pelvis.
The size of the renal pelvis plays a major role in the
gestational age and 7 mm afterwards.[2] In adults, 13% of the normal population have a transverse pelvic diameter of over 10 mm.[3]
Etymology and pronunciation
Like the
combining form pyelo- denotes the renal pelvis (pyelo- is not to be confused with pyo-). The words infundibulum and choana are other words for funnel-shaped cavities (which medical English got from the Latin and Greek words for "funnel", respectively), and the renal pelvis is sometimes called the renal infundibulum. The form *renal choana is logical but is not used
.
