En Bloc Enucleation of the Prostate Using a Surgical 532-nm Laser (GreenLEP) Technique: Initial Results

Abstract Objectives: To describe 532-nm Green laser enucleation of the prostate (GreenLEP) and assess its feasibility, safety, and short-term outcomes. Patients and Methods: Thirty consecutive patients with a prostate volume >80 cc and who underwent GreenLEP (by one surgeon) between July 2013 and March 2014 were prospectively evaluated. GreenLEP was conducted using the GreenLight HPS™ device (AMS, Minnetonka, MN), and morcellation was conducted using a Wolf™ morcellator. Clinical data on preoperative assessment, operative characteristics, and postoperative assessments of 6- to 12-month functional outcomes and complications were entered into a database. Results: GreenLEP was conducted effectively in all but one case, necessitating a conversion into open surgery for adenoma and clot removal. The median operative time was 60 minutes (range: 50–100). Perioperative complications included perforation of the prostatic capsule in five cases. The median hospital stay was 2 days (range: 2–5). Nine-month follow-ups ...
