title: Newly developed equipment and methods in the treatment of BPH: analysis of present status.
abstract: Benign prostatic hyperplasia (BPH) is the most common disease among the aged male population. A variety of symptoms are mainly caused by obstructive changes at the prostatic urethra. Transurethral resection (TURP) has been the gold standard of treatment, but new equipment and methods such as TUMT, HIFU, TUNA, and laser prostatectomy have been developed and are being tested for clinical application. Our experience with new equipment and methods show that their effectiveness has yet to be conclusively evaluated by objective parameters, while subjective improvements have been seen with less invasive treatments such as TUMT, HIFU and TUNA. Laser prostatectomy confirmed its advantages in hemostasis but comparison of each treatment is difficult because of different pathological changes created by different energy sources shown by MRI. Further studies are required to examine the new equipment and methods and for identification of the treatment of choice for BPH.
