title: Approach to Very Small (< 1.5 cm) Cystic Renal Lesions: Ignore, Observe, or Treat?
abstract: OBJECTIVE
  This article will review the current available literature on the prevalence, behavior, and pathology of very small (< 1.5 cm) cystic renal lesions. A summary of the recommended approach to these very small lesions is provided.
  
  
  CONCLUSIONS
  Limited data exist to guide the management of very small cystic renal lesions. Because most data favor benign or indolent behavior, vigorous workup of the very small cystic renal lesion seems unnecessary.
