Get to know the function of the renal pelvis and diseases that can attack it

The renal pelvis or renal pelvis is a funnel-shaped space located in the kidney and plays an important role in the process of collecting and removing urine. The renal pelvis consists of two parts. A number of diseases can attack this area, which can cause interference with its function.
Urine is the result of blood filtration carried out by the kidneys . Once produced, urine will pass through a number of parts, namely the renal pelvis, ureter, bladder, and excreted through the urethra when urinating.

Get to know the function of the renal pelvis and its parts

The renal pelvis is a space of about 0.4-1 cm in diameter with funnel-shaped branches located in the kidney . This area is directly related to the upper part of the kidney and ureteral connecting ducts.
The function of the renal pelvis is a temporary urine container, after being produced by the kidney filtration area (nephron), this urine will then be flowed into the ureter and removed from the body.
The renal pelvis consists of two parts, namely:


Calyces are the initial and largest part of the renal pelvis. This section consists of a space called the major calyx and smaller branches (minor calyx).
In calyces , there is a small bowl that functions to receive urine from the kidney filtration area (nephrons). This bowl is also a temporary container for urine before being channeled into the ureter.


Hilum is the end of the renal pelvis which is connected directly to the ureter. This section is a short channel at the end of the kidney. On the hilum, there are large blood vessels, namely the arteries and veins of the kidneys. This part also becomes the entrance and exit of blood from the kidneys.
When sorted, blood enters the kidneys to be filtered by an area called nephrons. Filtering results from nephrons or urine will enter the renal pelvis through calyces (reservoir bowl) and out through the hilum to be channeled into the ureter.

Diseases that can occur in the renal pelvis

The following diseases can attack the renal pelvis:

K arsinoma transitional cells

Transitional cell carcinoma is one cancer that can occur in the renal pelvis. However, the incidence is rare, only about 7% of all cancers in the kidney.
Symptoms of this condition can vary depending on the severity. A common symptom is blood appearing in the urine, and pain in the waist side or lower back does not go away.


Pyelonephritis is inflammation of the renal pelvis. This condition is generally caused by the spread of bacteria from bladder infections that get no treatment. Pyelonephritis can cause symptoms of back pain and fever.


Hydronephrosis in this condition, the blockage of urine flow or backflow of urine from the bladder, can cause the renal pelvis to swell. This condition can cause no symptoms, but in some patients, pain in the sides of the abdomen, waist and groin pain can occur.
The renal pelvis is part of the urinary tract system which functions as a temporary urine container before being drained into the ureter. Prevent diseases of the renal pelvis by adopting a healthy lifestyle . If you experience complaints in urination or pain in the abdomen, waist, or groin, immediately consult a doctor to get the right treatment.
