Hi, Thanks for writing in to us. At the age of 78 years, it can be usual to find a simple cyst measuring 1.1 x 1.7 cm cyst in kidney. Nothing needs to be done for this and a cyst or two is age related and can be considered as normal. The left kidney cyst is little bigger at 5.7 x 4.2 cm and can be followed up on repeat ultrasound scan after 6 months. The stones measuring 5 mm each in right kidney middle calyx and left kidney upper pole are not a concern if there is no obstruction to passage of urine and in the absence of symptoms like pain. He must continue to take adequate amounts of water to drink and visit washroom frequently. A repeat ultrasound can also help to know any increase in size after 6 months.
