title: A novel one lobe technique of thulium laser enucleation of the prostate: 'All-in-One' technique.
abstract: OBJECTIVE
  The thulium laser is the most recently introduced technology for the surgical treatment of benign prostatic hyperplasia (BPH). Until recently, most thulium laser enucleation of the prostate (ThuLEP) was performed by use of the three-lobe technique. We introduce a novel one-lobe enucleation technique for ThuLEP called the "All-in-One" technique. We report our initial experiences here.
  
  
  METHODS
  From June 2013 to May 2014, a total of 47 patients underwent the All-in-One technique of ThuLEP for symptomatic BPH performed by a single surgeon. All patients were assessed with the International Prostate Symptom Score (IPSS), transrectal ultrasonography, serum prostate-specific antigen (PSA), maximal urine flow rate (Qmax), and postvoid residual urine volume (PVR) before and 1 month after surgery. We reassessed IPSS, Qmax, and PVR 3 months after surgery. To assess the efficacy of the All-in-One technique, we checked the PSA reduction ratio, transitional zone volume reduction ratio, and enucleation failure rate.
  
  
  RESULTS
  The mean operative time was 82.1±33.3 minutes. The mean enucleation time and morcellation time were 52.7±21.7 minutes and 8.2±7.0 minutes, respectively. The mean resected tissue weight and decrease in hemoglobin were 36.9±24.6 g and 0.4±0.8 g/dL, respectively. All perioperative parameters showed significant improvement (p<0.05). No major complications were observed. The PSA reduction ratio, transitional zone volume reduction ratio, and enucleation failure rate were 0.81, 0.92, and 4.3%, respectively.
  
  
  CONCLUSIONS
  The All-in-One technique of ThuLEP showed efficacy and effectiveness comparable to that of other techniques. We expect that this new technique could reduce the operation time and the bleeding and improve the effectiveness of enucleation.
