Abstract:
Fifty-three patients with BPH have been evaluated and treated with TMT with a follow-up at 7 months. The prostate was heated transrectally to 42-43 degrees C and the treatment consisted of 5 to 6 sessions. The duration of each session was 60 minutes. The urodynamic parameters studied revealed an increase of the maximum flow rate and a decrease of the detrusor opening pressure as well as the detrusor pressure at maximum flow. A significant improvement in the amount of residual urine was seen in all patients. Based on the above, we propose TMT as a viable alternative to open surgical or transurethral removal of the prostate. Furthermore, TMT may serve as a preferred treatment option in patients with indwelling urethral catheters and highly increased surgical risk.
