Objective To evaluate the therapeutic effect of interstitial laser thermotherapy for the treatment of benign prostatic hyperplasia(BPH). Methods 100 patients with BPH were treated by interstitial Nd∶YAG laser thermotherapy from Nov 1993 to June 1998. The laser output power was 50 W. 1-6 points in a lobe were inserted and irradiated, 5 min per point. Results The patients were followed up for 3-24 months with satisfactory result. Amelioration of subjective symptoms and improvement of MFR were achieved in 70% of the 100 cases. Conclusions The results show that interstitial Nd∶YAG laser thermotherapy is safe and simple, especially indicated for high risk patients. Efficacy of the procedure is higly related to the experience of the operator and to the number of treatment points.
