Down syndrome with transient myeloid leukemia and urological abnormality.

On the other hand, urological anomalies are infrequently found both in the Down syndrome and leukemia patients. We report a case who had the rare combination of a urological anomaly along with Down syndrome and transient myeloid leukemia.
