The drainage tube of urine starts from each kidney. Its proximal end is like a receptacle called pelvis, which is usually inside the kidney and tapers to form the ureter - a long tube which takes urine to the bladder.
Any obstruction due to scarring of the renal pelvis or the ureter, can result in obstruction of urine and hence enlargement of the renal pelvis.
In some case, it also could be due to altered or abnormal growth and development of the kidney.
The exact condition needs to be determined, after due consideration of the complete medical history, your symptoms and findings of the ultrasound or CT of the abdomen. Hence you might consult with your doctor or a urologist who can advice you properly.
