What is benign prostatic hyperplasia?

People born after prostate growth and very slow. Progressive people after puberty growth accelerated to maintain a steady volume of the middle-aged, about 4 cm x 3 cm x 2 cm in size. After the show two trends: some people tend to shrink gradually reduce gland; Another part of people tend hyperplasia, glands gradually increasing. When the prostate hyperplasia to a certain extent, oppression of the urethra, caused a series of difficulties in urination symptoms, as in medicine on benign prostatic hyperplasia. Benign prostatic hyperplasia has called prostatic hyperplasia, will occur in those over 50 years old. According to statistics Europe and the United States, and other countries, older men in their incidence rates as high as 80 percent or more to reports lower, but also amounted to more than 50 percent. Because prostate happens in the exit of the bladder, urethra around the special position, in case of a hyperplasia, will urethral compression from all sides, so that the urine from the bladder disruption caused a series of urinary system diseases. Approaching prostate bear the brunt of the bladder, due to disruption from urine, bladder must use greater force can be narrowed through urine from the urethra, and bladder wall thickening of the detrusor compensatory, then, although the urine able fully discharged, but patients began to frequency, urgency, in particular the increase in symptoms of nocturnal enuresis. With continued prostate hyperplasia, a more narrow urethra, bladder wall strength has not completely excreted urine will not only be the remnants of the bladder urine, but bladder wall will be weak local protruding form of medical disease called diverticulitis . Hyperplasia more development, more expansion bladder wall, thinning, unable, at this time there will be patients with enuresis phenomenon, filling in medicine known as urinary incontinence. Then upper urinary tract involvement is, as always filling the bladder can not effectively discharge urine, the urine from the kidney would be unable to timely delivery of the ureter to the bladder, the result is bound to lead to renal pelvis (the cavity of the kidney) water, and oppression renal parenchyma, damage the kidneys function. The entire urinary tract obstruction occurred after infection and complications to come stones. As this patent discharge pipe cleaning fluid, and the pipeline obstructive sediment Music, the urinary tract obstruction makes bacteria breed easier, stone forming.
