title: A systematic review and meta-analysis of new onset hypertension after extracorporeal shock wave lithotripsy.
abstract: OBJECTIVE
  Previous studies on the association between extracorporeal shock wave lithotripsy (SWL) and new onset hypertension have only illustrated contradictory results. In order to illustrate the association between SWL and new onset hypertension, a meta-analysis of case-control and cohort studies was conducted.
  
  
  METHODS
  Relevant literature was searched using PubMed, EMBASE, and the Cochrane Central Search Library. A meta-analysis of the association between SWL and new onset hypertension was performed. Studies were pooled, and summary relative risk was calculated. Subgroup analyses were also conducted.
  
  
  RESULTS
  Eleven studies were eligible for our analysis. No statistical significance was detected between SWL and new onset hypertension (RR = 1.06, 95 % CI 0.83-1.35). No association was observed when stratified analyses were performed on age, gender, study design, bilateral SWL, and different machines.
  
  
  CONCLUSIONS
  Our analysis indicated that no association was found between SWL and the development of hypertension.
