Hyperthermic treatment in patients with benign prostatic hypertrophy

: Hyperthermic treatment was performed in 31 patients with benign prostatic hypertrophy (BPH). Eight patients of them had a urethral catheter because of urinary retention. The prostate was heated trans-rectally to 43-45 degrees C. The treatment consisted of 10 sessions of 60 min. each. To evaluate this treatment, the following parameters were determined before, during and one week after the last hyperthermia session: subjective symptoms score, and residual urine volume, uroflowmetry and transrectal ultrasound of the prostate as objective data. Symptoms score improve in all patients. Of 8 patients with a catheter, the catheter could be removed from 4 patients. There was no significant change in prostate volume, but significant decreases of residual urine volume, and increases of maximum flow rate and mean flow rate were observed. No adverse reactions were seen. Judging from the above results, this treatment is considered to be useful for patients with BPH.
