title: Photoselective vaporization of the prostate using the 120-W lithium triborate laser in enlarged prostates (>120 cc).
abstract: OBJECTIVE • To evaluate experience with high power LBO laser for large prostates
  
  
  METHODS
  • Prospective database of 288 men treated with PVP from November 2006-2009 • 33 men identified to have transrectal ultrasound measured prostate size >120 cc • All but 9 men not in urinary retention or on anticoagulant medications • Average ASA Score 2.25 (range 1-4) with 11 having an ASA Score of 3 or more
  
  
  RESULTS
  • Mean operating time and laser time 109 and 86 minutes respectively • IPSS, QoL and Qmax changes from baseline to 3 months for those not in retention were 24 to 8.6, 5.0 to 1.8 and 7.5 mL/s to 19.6 mL/s respectively • Post void residual in these men fell from a mean of 235 mL to 88 mL • Average fall in PSA was 38% for 22 men with paired PSA data • Post operative urinary retention in 4 men resolved. 2 late onset clot urinary retention
  
  
  CONCLUSIONS
  • Early results demonstrate PVP to be safe and efficacious on early follow up in a high risk group of patients with significantly enlarged prostates, anticoagulation and urinary retention.
