Results of deep prostatic hyperthermia applied with Thermex II in 525 benign prostatic hyperplasias.

Deep prostatic hyperthermia (DPH) with radiofrequency waves has been found to be of considerable beneficial value in benign prostatic hyperplasia. This study was performed on 525 patients. Madsen's criteria were used for symptom scoring. All the treatments were performed at 44.5 degrees C. Mean follow-up was 18 months. DPH is well tolerated and no severe complications were noted. Statistically meaningful changes of improvement were seen in mean flow rate and residual volume in 51% of the patients.
