It means that the collection system of the
kidney (for urine) has a slight aberration.
Normally all urine produced by the kidney from nephrons is collected and pushed to the ureter for final excretion from the body. Renal pelvis is a funnel like structure which collects urine and from the renal pelvis it goes to the ureter. Normally there is only one pelvis (funnel) for each kidney. If there is an additional collecting system which drains some parts of the kidney then it will be known as "extra renal pelvis".
Nothing to worry about . You should just know that you have it.
