title: Simple radiological indicators for staghorn calculi response to ESWL.
abstract: OBJECTIVE
  To evaluate staghorn calculi response to ESWL using simple radiological indicators which are stone size, stone homogeneity, and stone density.
  
  
  METHODS
  This is a prospective study of 60 patients with staghorn calculi where the majority had ESWL. The relationship between response and size, homogeneity and density is studied.
  
  
  RESULTS
  Single staghorn calculus less than 4 cm, heterogeneous with stone density similar to bone or a little denser than bone has best response to ESWL.
  
  
  CONCLUSIONS
  ESWL is useful as first line therapy for staghorn calculi less than 4 cm, heterogeneous with similar density to bone or a little denser than bone.
