title: Comparison of harmful gases produced during GreenLight High-Performance System laser prostatectomy and transurethral resection of the prostate.
abstract: OBJECTIVE
  To compare the gases generated from GreenLight High-Performance System (HPS) laser prostatectomy with Urosol or normal saline solution and transurethral resection and vaporization of the prostate (TURVP) with Urosol.
  
  
  METHODS
  A total of 36 smoke samples were collected from a continuous irrigation suction system attached to a Tenax absorber during transurethral surgery of the prostate. The gases were qualitatively and quantitatively analyzed by gas chromatography-mass spectrometry equipped with a purge and trap sample injector.
  
  
  RESULTS
  The gas produced during TURVP contained propylene, allene, isobutylene, 1,3-butadiene, vinyl acetylene, mercaptomethane, ethyl acetylene, diacetylene, 1-pentene, ethanol, piperylene, propenylacetylene, 1,4-pentadiene, cyclopentadiene, acrylnitrile, and butyrolacton. The types and amount of gas produced during HPS laser prostatectomy were fewer and smaller than during TURVP. However, 1,3-butadiene, a well-known human carcinogen, was also generated by HPS laser prostatectomy. HPS laser prostatectomy with saline produced a greater amount and number of gases than HPS laser prostatectomy with Urosol.
  
  
  CONCLUSIONS
  The surgical smoke produced from TURVP and HPS laser prostatectomy contains potentially harmful chemical compounds, although HPS laser prostatectomy produced less surgical smoke than TURVP. Urosol produced fewer types and a smaller amount of gas than normal saline during HPS laser prostatectomy.
