title: Thulium: YAG 2 mum cw laser prostatectomy: where do we stand?
abstract: BACKGROUND
  Tm:YAG 2 mum cw laser prostatectomy was introduced in the treatment of benign ptostatic obstruction (BPO). Since then numerous studies have been published proving efficacy during follow-up. However, different surgical techniques were introduced with different names for similar techniques that complicate comparison. This reviews aim was to compare published data and break down surgical techniques to core points. The authors define validate appellations for different surgical techniques and propose further use of these names to ensure homogenous nomenclature.
  
  
  METHODS
  All publications on Thulium:YAG prostatectomy have been included in this review. Articles were reviewed and associated due to the nature of the surgical approach. A systematic review of published data was performed.
  
  
  RESULTS
  Sixteen peer-reviewed publications dealing with Tm:YAG laser prostatectomy were printed since 2005. Four different surgical principles are described, including vaporization, resection and enucleation. Follow-up, up to 24 months, showed durable functional results.
  
  
  CONCLUSIONS
  Efficacy of Tm:YAG prostatectomy was shown. Surgical techniques include "Tm:YAG Vaporization of the prostate (ThuVAP)", "Tm:YAG VapoResection of the prostate (ThuVaRP)" and "Tm:YAG VapoEnucleation of the prostate (ThuVEP)". The almost blunt enucleation is introduced as "Tm:YAG laser enucleation of the prostate (ThuLEP)". The authors recommend the use of this neologism in the future. Further, large-scale prospective studies are needed to prove long-term durability. To initiate and canalize these upcoming studies, the Urothulium Study Group was founded, combining international experts on Thulium:YAG laser prostatectomy under its roof.
