title: [Greenlight KTP-laser photovaporization. Initial experience in a public hospital].
abstract: OBJECTIVE
  Despite the fact that transurethral resection of the prostate (TURP) continues being the gold standard for the surgical treatment of benign prostatic hyperplasia (BPH), the good results obtained with the use of new energy sources have led to their use in daily practice.
  
  
  METHODS
  Between September 2005 and January 2007, we have treated 63 patients with KTP laser photoselective vaporization of the prostate (PVP) in our service. Preoperatively we asked for IPSS, performed physical exam, digital rectal exam, abdominal , renal, bladder and prostatic ultrasound measuring postvoid residual volume, as well as flowmetry and PSA determination. Patients were revised after 1, 3, 6 and 12 months, undergoing uroflowmetry, IPSS, ultrasound and PSA; a satisfaction survey was also fulfilled at this interviews.
  
  
  RESULTS
  Mean age was 67 years (range 58-85) and mean preoperative prostatic volume was 48cc (range 34-67), mean preoperative IPSS was 17.7 and mean maximum flow 8.1 mL/s. 12 patients presented post void residual volume larger than 100 mL. Most patients presented medium or high anaesthetic risk. Mean operative time was 64 minutes (range 45-95). In most cases we used just one fibre, and mean energy released was 175,000 Joules (range 85,000-24,000). Mean hospital stay was 32.2 hours (range 19-55). In postoperative revisions we could state a significant decrease of IPSS, improvement in maximum flow, and also good or very good satisfaction degree in about 80% of the patients. Only 3 of them presented hematuria that needed to be attended by the urologist, none of them needed transfusion. One patient was admitted for severe urinary infection and eight patients referred irritative low urinary tract symptoms in their first postoperative checkup.
  
  
  CONCLUSIONS
  KTP laser PVP is a safe, reproducible technique with optimal short and middle term outcomes, which should be considered as the first choice surgical treatment in elderly patients, patients with chronic anaemic diseases or anticoagulated, and patients with high anaesthesic or surgical risk.
