Final answer:
Tumor lysis syndrome can lead to the formation of uric acid stones, causing obstruction and acute renal failure in the kidneys.
Step-by-step explanation:
When tumor lysis syndrome occurs, uric acid is released into the bloodstream. This can lead to the formation of uric acid stones, which may cause obstruction and acute renal failure. Uric acid stones can also be associated with conditions like gout, leukemias/lymphomas treated by chemotherapy, and acid/base metabolism disorders.
