Benign prostatic hyperplasia (BPH), also called benign enlargement of the prostate (BEP), adenobromyomatous hyperplasia and benign prostatic hypertrophy (technically incorrect usage), is an increase in size of the prostate. BPH involves hyperplasia of prostatic stromal and epithelial cells, resulting in the formation of large, fairly discrete nodules in the periurethral region of the prostate. When sufciently large, the nodules compress the urethral canal to cause partial, or sometimes virtually complete, obstruction of the urethra, which interferes with the normal ow of urine. It leads to symptoms of urinary hesitancy, frequent urination, and increased risk of urinary tract infections, urinary retention, or contributes to or cause insomnia. Although prostate specic antigen levels may be elevated in these patients because of increased organ volume and inammation due to urinary tract infections, BPH does not lead to cancer or increase the risk of cancer. Since the wavelength is highly absorbed by water and haemoglobin, so the vaporization and coagulation to the prostate tissue can be realised simultaneously. The high power laser energy is transmitted by the special side fiber through the endoscopy in visible; its currently the most advanced minimally invasive treatment method. Compared to the traditional surgery, this procedure is a low- trauma, low-pain, low-risk, comfortable and fast recovery.
