The name reflects that each renal pelvis collects urine from the calyces and funnels it into the ureter like a wash basin collects water and funnels it into a drain pipe. The renal pelvis is occasionally called the pyelum (from Greek πύελος pýelos , "trough", ‘anything hollow’), and the combining form pyelo- denotes the renal pelvis ...
Its central part presents a deep longitudinal fissure, bounded by prominent overhanging anterior and posterior lips. This fissure is a hilum that transmits the vessels, nerves, and ureter. From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney. On the left hand side the hilum is located ...

The tip, or papilla, of each pyramid empties urine into a minor calyx; minor calyces empty into major calyces, and major calyces empty into the renal pelvis. This becomes the ureter. At the hilum, the ureter and renal vein exit the kidney and the renal artery enters. Hilar fat and lymphatic tissue with lymph nodes surround these structures.
Hydronephrosis describes hydrostatic dilation of the renal pelvis and calyces as a result of obstruction to urine flow downstream. Alternatively, hydroureter describes the dilation of the ureter, and hydronephroureter describes the dilation of the entire upper urinary tract (both the renal pelvicalyceal system and the ureter).
To monitor a kidney transplant. [1] The symptoms that a person may experience that cause the test to be requested may be blood in the urine, abdominal pain, abnormal kidney function tests, and frequent urinary tract infections (of which symptoms may include the need to pass urine frequently, pain on urination, and worsening urinary incontinence ...
Renal neoplasms and abscesses are rare in ruminants. [189] Obstructive uropathy (obstruction of urine flow from one or both kidneys) can lead to hydronephrosis with dilatation of the renal pelvis. [190] Kidney stones can also be formed in the kidneys (nephrolithiasis). [191] The cause of acute kidney injury in most cases is ischemic or toxic ...
Urine is excreted through the renal papillae into the calyces and then into the pelvis, ureter, and bladder. [62] [28] Then it is excreted outside through the urethra. [64] In monotremes, the ureters open into the urogenital sinus, which is connected to the urinary bladder and cloaca, [65] and urine is excreted into the cloaca instead of the ...
