title: [Six-o'clock tunnel holmium laser enucleation of the prostate: a modified procedure for benign prostate hyperplasia].
abstract: OBJECTIVE
  To evaluate the safety and effectiveness of a modified method of holmium laser enucleation of the prostate (HoLEP)--6-o'clock tunnel HoLEP for the treatment of benign prostate hyperplasia (BPH).
  
  
  METHODS
  We included 112 cases of BPH in this study, 57 treated by 6-o'clock tunnel HoLEP (experimental group) and the other 55 by conventional HoLEP (control group). We compared the operation time, volume of the resected prostatic tissue, intraoperative blood transfusion, volume of bladder irrigation solution, postoperative hemoglobin change, and incidence of urinary incontinence between the two groups.
  
  
  RESULTS
  Statistically significant differences were observed between the experimental and control groups in the operation time ([56.01 ± 8.62] min vs [68.65 ± 9.08] min), cases of intraoperative blood transfusion (0 vs 2), volume of bladder irrigation solution ([27.51 ± 3.67] L vs [36.89 ± 6.47] L), postoperative hemoglobin decrease ([10.70 ± 2.50] g/L vs [12.60 ± 3.30] g/L), and cases of postoperative stress-induced urinary incontinence (2 vs 7) (all P <0.05). One-month follow-up revealed smooth urination in both groups of patients but no true urinary incontinence or secondary bleeding in either.
  
  
  CONCLUSIONS
  Modified 6-o'clock tunnel HoLEP can significantly reduce the operation time, bladder irrigation, and intraoperative bleeding, and therefore can be used as a safe and effective option for the treatment of BPH.
