D30.1: Benign neoplasm: Renal pelvis

There are 2 kidneys in the body. There is one on each side of the spine just below the ribcage. Each kidney is made up of renal tissue and a renal pelvis. The renal tissue purifies the blood and, by doing so, produces urine. The urine gathers in the renal pelvis. You have abnormal tissue in the renal pelvis.

When there is abnormal growth of tissue in an organ, then this is referred to as a tumor. The tissue in the body is made up of cells. A tumor disorder involves the cells multiplying more than normal. This results in abnormal or excess tissue forming. A tumor can be benign or malignant. Benign tumors do not destroy the healthy tissue and do not spread throughout the body.

This means you sometimes don’t have any symptoms with this disease. However, the tumor may cause the urine to no longer drain properly, for example. You may also have a feeling of pressure or pain. A tumor can also bleed.
