[|Human|] Hi I observed a lump in the left back of my husband It is below the left rib cage and near the left kidney . My husband suffered from a sharp pain due to stone in the left kidney a few months before. The stone passed away later and doctor suggested to intake more citrus food diet. I am worried now is this lump related to some kidney problem or just a cyst . Can you please suggest something.
[|AI|]  Hello and welcome to ChatDoctorA lump on the left back can be due to enlargement of the structures/ organs in that region, which are:Kidney, ureter, soft tissue growth, lymph nodes etc. You should get an ultrasound done soon. As you have mentioned that your husband had had a stone in the same kidney, there can be a recurrence of the stone.a large stone can obstruct the passage of urine from the kidney and cause its enlargement, which can be palpable. Development of cysts in kidney, however this is not very common after kidney stones. A kidney tumor can also form a palpable mass. Other soft tissues in the region like fat, muscle, fibrous tissue can also form a palpable mass. Lymph nodes in the region can get enlarged due to inflammation or due to malignancy. An ultrasound of pelvis along with urine examination is needed as soon as possible/ Thanks and take care Chat Doctor.
