title: [Comparison of 2 µm continuous-wave laser enucleation of the prostate and transurethral resection of the prostate for benign prostatic hyperplasia].
abstract: OBJECTIVE
  To compare the safety and efficacy of RevoLix 120 W 2 µm continuous-wave (cw) laser enucleation of the prostate with transurethral resection of prostate (TURP) in patients with symptomatic benign prostatic hyperplasia (BPH). And to evaluate clinical value of 120 W 2 µm cw laser enucleation.
  
  
  METHODS
  All 168 patients with BPH underwent 2 µm cw laser enucleation (n = 88) or TURP (n = 80) between January 2010 and January 2011. The operative time, drop in hemoglobin, drop in serum sodium, indwelling catheterization time and operative complications were recorded. International prostate symptom score (IPSS), quality of life (QOL), urinary peak flow rate (Qmax) and post-voiding residual urine (PVR) were also compared.
  
  
  RESULTS
  The mean operative time was slightly longer in the 2 µm laser group ((63.2 ± 21.6) min) than the TURP group ((59.4 ± 18.6) min) (P > 0.05). Transfusions were not necessary in 2 µm laser group. Catheter indwelling time were (1.8 ± 0.6) days vs. (3.5 ± 2.6) days in 2 µm laser group than in TURP group (t = 3.912, P < 0.05). All cases were followed up for 3 - 12 months, the IPSS, QOL, Qmax and PVR were 6.1 ± 2.0, 4.4 ± 1.6, (18.8 ± 4.8) ml/s and (21.6 ± 16.5) ml in the 2 µm laser group, and were 6.3 ± 2.4, 1.9 ± 1.1, (18.4 ± 4.2) ml/s, (23.2 ± 14.6) ml in TURP group respectively. All the markers were improved significantly compared with that of preoperative in both groups (t = 12.453 - 26.213, P < 0.01), but no statistical differences could be found between the two groups. Perioperative complications were less in the 2 µm laser group.
  
  
  CONCLUSIONS
  The 120 W 2 µm cw laser enucleation is an novel excellent treatment for BPH as well as TURP, and has the advantage of significantly less blood loss, shorter hospitalization, shorter catheter indwelling time and rapid recovery after surgery.
