title: Outcome of extracorporeal shock wave lithotripsy at B and B Hospital.
abstract: BACKGROUND
  Extracorporeal Shock Wave Lithotripsy is an effective noninvasive method to treat urolithiasis. This study aims to evaluate its outcome and determine appropriate management strategies for urolithiasis.
  
  
  METHODS
  It was a prospective study which included one hundred patients who underwent ESWL for the management of solitary urolithiasis during a period of eight months (December 2007-August 2008). Status of stone and complications were observed and managed accordingly within a period of six postoperative weeks.
  
  
  RESULTS
  Out of 100 patients, 93% had complete clearance of stone by the end of six postoperative weeks. Seven percent of the patients required adjunct invasive intervention including open surgery in 3%. Number of sessions of ESWL was found to increase as the size of stone increased. However, in three patients stones were completely refractory to ESWL even after two consecutive sessions.
  
  
  CONCLUSIONS
  ESWL is highly effective noninvasive modality in the management of urolithiasis in appropriately selected patients.
