Large renal cyst

78 year old man with pain in the right loin. Ultrasound showed a large 3.5cm Bosniak type 1 renal cortical cyst. The cyst is exophytically arising from the upper pole of the right kidney.
Renal cyst may cause pain either when it is large (due to stretching of the capsule) or there is bleeding within the cyst.
