title: [Causes, location and management of BPH surgery-related urethral stricture].
abstract: OBJECTIVE
  To analyze the possible causes of BPH surgery-related urethral stricture and summarize the experience in its clinical management.
  
  
  METHODS
  The clinical data of 37 cases of BPH surgery-related urethral stricture were analyzed retrospectively. The patients averaged 68.5 years in age, of whom 12 had the history of open surgery, and 25 transurethral surgery. Anterior urethral stricture was found in 6 cases, and posterior urethra in stricture 31. Thirty-five cases were treated by holmium laser urethrotomy (HLU) or a combination of HLU with transurethral resection of the scar in the stenotic segment, and the results were evaluated based on the maximum flow rate (Qmax).
  
  
  RESULTS
  Two cases of full penile urethral stricture were treated by urinary diversion, and all the rest by urethral stricture surgery. Catheters were indwelt in 4 cases of urethral stenosis for 5-7 days post-operatively, and smooth urination was achieved after their removal, with a Qmax of > 15 ml/s. Another 31 cases of membranous urethral stricture received catheter indwelling of 2 -4 weeks and were followed up for 1 - 21 (mean 11. 5) months, of whom 23 experienced satisfactory voiding, with an average Qmax of 14.3 ml/s, and the other 8 poor voiding, with a Qmax of < 8 ml/s.
  
  
  CONCLUSIONS
  HLU or a combination of HLU with transurethral resection of the scar in the stenotic segment is an effective method for the treatment of BPH surgery-related urethral stricture. And conscientiously performed BPH surgery can reduce the incidence of urethral stricture.
