title: Application of two micron laser vaporesection combined with transurethral resection of the prostate in treatment of benign prostatic hyperplasia: analysis of 340 cases.
abstract: OBJECTIVE
  To evaluate clinical efficacy and safety of two micron laser vaporesection combined with transurethral resection of the prostate (TURP) in treating benign prostatic hyperplasia (BPH).
  
  
  METHODS
  In total, 340 BPH patients aged 62-86 years, were treated with two micron laser vaporesection plus TURP. Mean prostatic volume was measured as 38-182 ml. Operative time, intraoperative hemorrhage volume, time of postoperative bladder irrigation, time of indwelling urinary catheter and surgical complications were examined. International Prostate Symptom Score (IPSS), quality of life score (QOL), maximal urinary flow rate (Qmax) and post void residual urine volume (PVR) were analyzed.
  
  
  RESULTS
  All cases underwent the surgery successfully. No transurethral resection syndrome was noted. Mean operative time was (72±15) min. Mean intra operative hemorrhage volume was (48.4±13.0) ml. Four patients were transfused with 2 U of suspended red blood cells. Time of postoperative bladder irrigation ranged from 0.5-2.5 d. Time of indwelling urinary catheter was 3-6 d. After removing urinary catheter, mild urinary irritation symptoms were noted in 19 cases. Ten patients developing urinary infection were recovered following anti-infection therapy. One with secondary urethral stenosis was healed after urethral dilatation for three times. Postoperative IPSS, QOL, Qmax and PVR were (6.0±2.0), (2.0±0.2), (18.5±1.6) ml/s and (11.0±4.0) ml, significantly improved compared with preoperative levels (all P<0.05). Fifty eight cases with normal sexual function retained sexual function postoperatively and had no retrograde ejaculation.
  
  
  CONCLUSIONS
  Two micron laser vaporesection plus TURP is efficacious and safe in treating BPH with mild lower urinary tract symptoms and perioperative complications.
