Primary study objective:

• To assess the current indications for HPS greenlight laser treatment and the treatment outcomes in terms of objective and subjective improvement

 

Secondary study objectives: 

• To assess the peri-operative morbidity (30 days) by using the Clavien system.
• To define risk factors for the development of peri-operative morbidity after HPS greenlight laser treatment.

The following variables will be included to correlate in a logistic regression and uni/multivariate analysis:

• The use of antibiotics and incidence of infections.
• Possible differences in morbidity.
• Specific medical conditions (age, BMI, DM, anticoagulants, cardiovascular disease) versus outcome and morbidity
• Outcomes in complicated cases (coumadine use, large prostates, etc)
• To define the learning curve
• To study differences between lower and higher volume sites
