Child is having MRI to evaluate 1cm complex kidney cyst. Soonest appt is a month from now. What is the risk of waiting this long? Could it grow?

Minimal: If the child is asymptomatic and this was an incidental finding then it is unlikely going to progress fast. It also depends on age of child and any other risk factors. If it were my child I would not be concerned about waiting a month if he was otherwise healthy. ...Read more

If a 1cm complex kidney cyst has been stable in size for 4 months, what are the chances it is cancer and is it possible for it to spread at this size?

Renal cyst: The fact that it is small and stable after 4 months is a good sign. However another renal ultrasound should be done in 6 months to look for growth or change in structure. There is an increased risk of malignancy with a complex cyst and it should be watched closely ...Read more

How significant is the finding of protein in the urine in a child? If the child has a complex kidney cyst? Repeat sample 1st morning urine showed none

How significant is the finding of protein in the urine in a child? If the child has a complex kidney cyst? Repeat sample 1st morning urine showed none

Not very significant: Children frequently "spill" small amounts of protein in their urine when they are very active during the day from their high metabolism and rapid muscle growth. That's why we then check a first morning urine sample. If there is no protein with the morning urine, nothing to worry about at this time. I check a yearly urine sample on these kids, but otherwise no restrictions or reasons to worry. ...Read more

Liver enzymes (AST, ALT) elevate with liver cell damage however AST elevations can also come from anomalies in other organs, (eg. heart, kidneys & more) & does not point specifically to liver. Your child's AST's are very mildly elevated. With so little info given, suggest you see doctor to discuss cancer fears & to better understand child's condition ...Read more

Which is safer for a child- MRI under deep sedation, or low-dose CT scan with no sedation? This is to evaluate complex kidney cyst.

It depends: The best study really depends on what the doctor is trying to evaluate. Certainly having no sedation may be safer than a procedure with sedation, but may not give as accurate a picture of the kidneys. Children are frequently sedated for imaging procedures because excessive movement will make the study unreadable. ...Read more
