CT Urography
Good Day! 1. Calculus in lower pole - you have a stone on the lower pole of your left kidney, it is a small stone 0.4 cm and can be treated medically for stone dissolution. It is too small to be treated surgically or on any invasive procedure. I would suggest Chat Doctor. 2. Cortical cysts - cortical cyst or simple cyst are not clinically significant. It does not cause pain nor does it become cancer.  No need to be worried about this finding.3. Extra renal pelvis - extra renal pelvis means that you were born with the tube that connects your kidney to your urinary bladder developed outside the kidney. It is a normal variant and does not have a clinical consequence. Thank You.
