BPH(Benign Prostatic Hyperplasia) is the medical abbreviation of benign prostatic hyperplasia, which is often referred to as "prostatic hyperplasia". Bladder irritation and obstruction are the main manifestations, which is the most common benign disease among the causes of dysuria in elderly men.
1. The nature of the disease.
BPH refers to the non-cancerous (benign) increase and volume increase of prostate tissue. It is a common benign disease of urinary system in middle-aged and elderly men, mostly in men over 50 years old, which is mainly related to the increase of age and the change of hormone (androgen/estrogen) level in the body.
2. Pathogenesis.
The prostate is located below the bladder and surrounds the initial part of the urethra. With the increase of age, the cells of prostate (especially the transitional zone around urethra) proliferate, which leads to the increase of prostate volume, which in turn squeezes the urethra, resulting in bladder outlet obstruction and increased urination resistance, thus causing a series of lower urinary tract symptoms (LUTS).
3. Common symptoms.
Symptoms of bladder irritation: frequent micturition, urgent micturition and increased nocturia (frequent nocturnal onset). Symptoms of micturition obstruction: dysuria (waiting for micturition, thinner urinary line, strenuous micturition), dripping after micturition, and feeling of incomplete micturition. Symptoms of complications: acute urinary retention (complete inability to urinate), repeated urinary tract infections, hematuria, etc. may occur in severe cases.
4. Clinical significance.
Although BPH will not turn into prostate cancer, it will seriously affect the quality of life of patients. If it is not intervened in time, it may lead to complications such as renal function damage. When symptoms appear, it is suggested to go to the urology department in time, make a definite diagnosis through ultrasound, urine flow rate and other examinations, and take observation and follow-up, drug treatment or surgical treatment according to the severity of symptoms.

A beam of 2.1-micron light is rewriting the history of the treatment for "stones and hyperplasia".
Lithotripsy is recognized as the "gold standard". Whether it is hard oxalate calcium stones, tough cystine stones, or oddly shaped antler-shaped stones, holmium laser can efficiently crush them; combined with the Moses pulse modulation technology, the displacement of stones is smaller and the efficiency is higher. It can even "use one light for multiple purposes" - during lithotripsy, it cuts open the inflammatory polyps surrounding the stones, treats ureteral stenosis, and solves multiple problems in one surgery.
