Abstract:
From August 1991 to July 1992, 262 patients of benign prostatic hyperplasia (BPH) were treated with transurethral microwave thermotherapy (TUMT). Among those, 64 patients were followed up more than I year and 26 patients were followed up more than 4 years without other treatment. The patient`s age ranged from 49 to 80 years with a mean of 64.3 years. Prostate volume determined by transrectal ultrasonography ranged from 27.0cm3 to 73.6cm3, the mean 40.8cm3. After I year, maximum flow rate increased from 8.1+/-2.3ml/sec to 11.5+/-3.6ml/sec, Madsen symptom score decreased from 12.6 +/-3.8 to 6.6+/-4.7, and residual urine volume decreased from 75.6+/-33.5ml to 43.4+/-35.3ml. Complete response of maximum flow rate and Madsen symptom score observed in 17.2% in each group, partial response in 50.0% and 40.6%, and non-response in 32.8% and 42.2%. Improvement of subjective symptoms were evaluated by patients themselves and divided into 3 groups: ""satisfactory"" was 28.1%, ""acceptable"" 34.4%, and ""not effective"" 37.5%. Complications were i case of erectile dysfunction and 4 cases of dry ejaculation. Among the 64 patients who were followed up more than 1 year, 26 patients (40.6%) were remained without other treatment, 20 (31.3%) patients were medicated additionally, 11 (17.2%) patients required TUR-P during the follow-up period due to persistent symptoms, and 7 (10.9%) patients were performed re-TUMT. In conclusion, TUMT could be useful, safe and inexpensive treatment for BPH when it is applied selectively and should be advanced in mechanism to be more effective in treatment of BPH.
