### input:
My husband has had upper abdominal pain for almost 2 years. It is constant sharp pains which makes him curled up in a ball for a good part of the day. They have done alot of tests and is now being sent to a UCSF GI dr. thinking it may be his pancreas or bile ducts. I received his records to take to this dr. and noticed that he had a 2 x 2 0.1 cm cyst with intrinsic debris. This report was taken 5/11 and their recommendations were to do a renal ultrasound which was never done as we didn t know he even had a cyst until we received these records the other day. Spoke to a dr a Kaiser and they say it is nothing because its small and hasn t grown and many people have them. If he didn t have this sharp constant pain since then I wouldn t worry but I think further testing on this cyst is required. He has no other symptoms besides the sever abdominal pain. What do you think

### output:

Hi and thank you for using Chat Doctor. Cysts in the kidneys are commonly found in people as we age.  The finding of a few simple cysts on an ultrasound in and of itself would not warrant further evaluation. The findings of a cyst that would warrant further evaluation would be large size (right around where his are or greater), complexity of the cyst by imaging which would indicate that it is not just fluid-filled or any masslike characteristics. If the original imaging was done in May 2011 and there has been no change in the size, it would seem unlikely to be of any significance. To reassure yourself, I would suggest that you request an MRI to further characterize the cyst as well as urine cytology. Benign findings on an MRI and negative urine cytology would be highly reassuring without the need for further extensive workup.
