Maybe: Blood urea nitrogen on a lab chemistry test is a protein metabolism waste product that is normally removed by the kidneys through the urine. High BUN levels can be due problems like dehydration, kidney or heart failure, etc... With a leukemia, if many of the bad cells are suddenly destroyed with treatment, one can get a tumor lysis syndrome in which decreased kidney function can cause high bun.

CLL: Chronic lyphocytic leukemia can cause accelerated cell turn over. Especially if one of the rare individuals who are being treated. Can lead to high urea. Cll can cause organ involvement including kidneys. Best to discuss with your doctor.
