Abstract
Benign prostatic hyperplasia (BPH) is a common disease affecting past middle-aged males. Surgical treatment has been successfully used since the early 1900s. Currently, nonsurgical treatment modalities are under intensive study in BPH patients who have relative contraindications to surgery. Transurethral microwave hyperthermia (TUHT) is one of these modalities under study. TUHT has been applied in five to ten treatment sessions. The treatments were well tolerated with no major toxicity being reported. In BPH patients with predominance of median lobe or median bar enlargement the treatment efficacy was reduced to 30%. The effectiveness of TUHT was of particular importance in patients who had urinary retention. In this group 72% had normal voiding for 12 months or longer. A strong correlation between applied temperature and response to treatment was demonstrated. Current efforts are directed toward optimization of technique and treatment schedule. A phase III prospective randomized trial is required to define the role of TUHT in the management of BPH patients.
