65 consecutive cases with symptomatic benign prostate hypertrophy were treated with transurethral radiowave thermotherapy (TURF) using the Thermex-II at a temperature of 44.5 degrees C. We report uroflowmetry and symptom scores after a follow-up of 6 months. The mean age was 63 years, the mean maximal flow (Qmax) was 8.3 ml/s, mean voided volume was 195.6 ml, mean residual urine was 60.7 ml and the mean Madsen symptom score 9.7. Values at baseline and at 1, 3 and 6 months after TURF are discussed. The mean subjective symptom score dropped to 6.3 (p < 0.01). In the entire group, the objective measure scores (OMS) did not change significantly. However the OMS improved significantly in a subgroup with a Qmax < 10.0 ml/s. The Madsen symptom score improved in 70% of the cases after 6 months.
