The process of benign prostatic hyperplasia

Treatments You can do a lot to take care of yourself and give your body what it needs. For most men, one of those changes is that the prostate gets bigger. Your prostate surrounds part of your urethra, the tube that carries urine and semen out of your penis.

The process of benign prostatic hyperplasia

BPH can be a progressive disease, especially if left untreated. Incomplete voiding results in residual urine or urinary stasis, which can lead to an increased risk of urinary tract infection.

This means that androgens must be present for BPH to occur, but do not necessarily directly cause the condition.

The process of benign prostatic hyperplasia

This is supported by evidence suggesting that castrated boys do not develop BPH when they age. On the other hand, some studies suggest that administering exogenous testosterone is not associated with a significant increase in the risk of BPH symptoms, so the role of testosterone in prostate cancer and BPH is still unclear.

Further randomized controlled trials with more participants are needed to quantify any risk of giving exogenous testosterone. DHT can act in an autocrine fashion on the stromal cells or in paracrine fashion by diffusing into nearby epithelial cells. In both of these cell types, DHT binds to nuclear androgen receptors and signals the transcription of growth factors that are mitogenic to the epithelial and stromal cells.

DHT is ten times more potent than testosterone because it dissociates from the androgen receptor more slowly. Diet[ edit ] Studies indicate that dietary patterns may affect development of BPH, but further research is needed to clarify any important relationship.

Men older than 60 in rural areas had very low rates of clinical BPH, while men living in cities and consuming more animal protein had a higher incidence. Misrepair-accumulation aging theory [32] [33] suggests that development of benign prostatic hyperplasia is a consequence of fibrosis and weakening of the muscular tissue in the prostate.

However, repeated contractions and dilations of myofibers will unavoidably cause injuries and broken myofibers.

Myofibers have a low potential for regeneration; therefore, collagen fibers need to be used to replace the broken myofibers.

Such misrepairs make the muscular tissue weak in functioning, and the fluid secreted by glands cannot be excreted completely. Then, the accumulation of fluid in glands increases the resistance of muscular tissue during the movements of contractions and dilations, and more and more myofibers will be broken and replaced by collagen fibers.

Pathophysiology[ edit ] Benign prostate hyperplasia As men age, the enzymes aromatase and 5-alpha reductase increase in activity. Aromatase and 5-alpha reductase are responsible for converting androgen hormones into estrogen and dihydrotestosteronerespectively. This metabolism of androgen hormones leads to a decrease in testosterone but raised levels of DHT and estrogen.

Both the glandular epithelial cells and the stromal cells including muscular fibers undergo hyperplasia in BPH. The anterior lobe has little in the way of glandular tissue and is seldom enlarged. Carcinoma of the prostate typically occurs in the posterior lobe — hence the ability to discern an irregular outline per rectal examination.

The earliest microscopic signs of BPH usually begin between the age of 30 and 50 years old in the PUG, which is posterior to the proximal urethra. The degree of LUTS does not necessarily correspond to the size of the prostate. An enlarged prostate gland on rectal examination that is symmetric and smooth supports a diagnosis of BPH.Benign Prostatic Hyperplasia and Microscopic Pathophysiology The microscopic pathophysiology of benign prostatic hyperplasia demonstrated the hyperplastic process that occurs in the gland.

The hyperplasia is a result of the swollen prostate, which blocks the normal flow of urine from the bladder through the urethra to be expelled. Oct 31,  · This is a Learning in 10 voice annotated presentation (VAP) on Benign Prostatic Hyperplasia.

Benign prostatic hyperplasia (BPH) is an enlarged prostate.

Benign Prostatic Hyperplasia and Microscopic Pathophysiology

The prostate goes through two main growth periods as a man ages. The first occurs early in puberty, when the prostate doubles in size.

The second phase of growth begins around age 25 and continues during most of a man's life. As you age, your prostate may get larger. Benign Prostatic Hyperplasia. According to the National Institutes of Health, more than 50 percent of men over 60 and 90 percent of men over 70 are living with benign prostatic hyperplasia (BPH).

It is the most common disorder of the prostate. This condition is caused by changing hormonal levels that increase the size of the prostate.
