Transurethral hyperthermic treatment in patients with benign prostatic hypertrophy

: Transurethral hyperthermic treatment was performed on 30 patients with benign prostatic hypertrophy (BPH). Two patients had a urethral catheter because of urinary retention. The prostate was heated transurethrally. The treatment consisted of 3-8 sessions of 60 min. each. To evaluate this treatment, the following parameters were determined before and 1-5 weeks after the last hyperthermia session; subjective symptoms score, and as objective data residual urine volume and uroflowmetry. The symptoms score improved in 25 (83%) patients. Of 2 patients with a catheter, the catheter could be removed from 1 patient. Although there was no change in prostatic volume, significant decreases in 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.
