title: [Treatment of benign prostatic hyperplasia with laser through the endoscope].
abstract: OBJECTIVE
  To evaluate the effect of transurethral laser prostatectomy (TULP) and its relation with the size of prostate.
  
  
  METHODS
  469 benign prostatic hyperplasia receiving TULP from 1988 to 1998 were reviewed retrospectively, and the methods of operation and preoperative and postoperative symptom were compared. The effect of 233 patients undergoing TULP was compared with the size of the prostate.
  
  
  RESULTS
  The average value for IPSS of 469 patients decreased from 26.7 (preoperation) to 14.2 (postoperation). The mean value of maximum uroflow rate increased from 6.2 ml/s (preoperation) to 11.8 ml/s (postoperation). No difference was seen in postoperative effect between the transurethral contact and noncontact laser prostatectomy. If the estimating weight of prostate exceeded 50 g, the maximum flow rate after 3 years was decreased evidently, the value of IPSS increased to over 20.
  
  
  CONCLUSIONS
  If the estimating weight of prostate is less than 50 g, TULP is indicated.
