Leukoplakia associated with renal tuberculosis in the chemotherapeutic era.

The association of renal tuberculosis and leukoplakia of the renal pelvis was quite common in the prechemotherapy era of tuberculosis but has apparently not been seen since effective drugs became available. Despite a prompt response of the tuberculosis to chemotherapy the leukoplakia formation with intermittent passage of keratinised material continued. Surgical removal of the accumulated material was of no lasting benefit.
