High energy microwave thermotherapy for symptomatic benign prostatic enlargment: predictive parameters of long term outcome.

OBJECTIVES: High-energy transurethral microwave thermotherapy (HE-TUMT) has become one of the most preferred minimally invasive procedure for the treatment of benign prostatic enlargement (BPE). In this study we report the long term results in a subset of patients treated with the 30-minute high energy protocol. PATIENTS AND METHODS: A total of 135 patients were treated with TUMT Prostasoft 3.5. The International Prostate Symptom Score (IPSS), Madsen Symptom Score (MSS), Quality of Life (QoL) score, peak urinary flow rate (Qmax) and post-voiding residual urine volume (PVR) were assessed at baseline and at 12, 24, 36, 48 and 60 months after treatment. RESULTS: The mean follow-up period was 46.1 months. The mean IPSS at baseline was 17.8 and decreased to 5.6 at 60 months (p 10 ml/sec (p = 0.04). CONCLUSIONS: These data shows a high response rate obtained with 30-minute TUMT protocol and a durability of response up to 5 years after treatment, making this procedure a safe and effective alternative to TURP in selected patients.
