Medical Treatment fro Benign Prostatic Hyperplasia (BPH)/Lower Urinary Tract Symptoms (LUTS)
Benign prostatic hyperplasia BPHalso called prostate enlargementis a noncancerous increase in size of the prostate gland. The cause is unclear. Treatment options including lifestyle changes, medications, a Prostata. BPH of procedures, and surgery. About million men are affected globally.
BPH is the most common cause of lower urinary Prostata. BPH symptoms LUTSwhich are divided into storage, voidingand Prostata.
BPH which occur after urination. 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.
Most experts consider androgens testosterone and related hormones to play a permissive Prostata. BPH in the development of BPH. This means that androgens must be present for BPH to occur, but do not necessarily directly Prostata. BPH the condition. This is supported by evidence suggesting that castrated boys do not develop BPH when they age. On Prostata. BPH 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 Prostata.
BPH is still unclear. Further randomized controlled trials with Prostata. BPH participants are needed to quantify any risk of giving exogenous testosterone. Dihydrotestosterone DHTa metabolite of testosterone, is a critical mediator of prostatic growth. 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. Testosterone promotes prostate cell proliferation,  but relatively low levels of serum testosterone are found in patients with BPH. While there is some evidence that estrogen may play a role in the cause of BPH, this effect appears to be mediated mainly through local conversion of androgens to estrogen in the prostate tissue rather than a direct effect of estrogen itself.
InGat et al. Studies indicate Prostata. BPH 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 Prostata. BPH low rates of clinical BPH, while men living in cities and consuming more animal protein had a higher incidence.
Prostata. BPH prostatic hyperplasia is Prostata. BPH age-related disease. Misrepair-accumulation aging theory   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 Prostata. BPH low Prostata. BPH 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. As men age, the enzymes aromatase and 5-alpha reductase increase in activity. These enzymes are responsible for converting androgen hormones into estrogen and dihydrotestosteronerespectively. This metabolism of androgen hormones leads to a decrease in testosterone but increased levels of DHT and estrogen.
Both the glandular epithelial cells and Prostata. BPH stromal cells including muscular fibers undergo hyperplasia in BPH.
Anatomically the median and lateral lobes are usually enlarged, due to their highly glandular composition. 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 Prostata. BPH examination.
The earliest microscopic signs of BPH usually begin between the age of 30 Prostata. BPH 50 years old in the PUG, which is posterior to the proximal urethra. The clinical diagnosis of BPH is based on a history of LUTS lower Prostata.
BPH tract symptomsa digital rectal exam, and exclusion of other causes of similar signs and symptoms. 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.
Urinalysis is typically performed when LUTS are present and BPH is suspected to evaluate for signs of a urinary tract infection, glucose in the urine suggestive of diabetes Prostata. BPH, or protein in the urine suggestive of kidney disease.
The Prostata. BPH diagnosis for LUTS is broad and includes various medical Prostata. BPH, neurologic disorders, and other diseases of the bladder, urethra, and prostate such as bladder cancerurinary tract infection, urethral strictureurethral calculi stoneschronic prostatitisand prostate cancer.
This may Prostata. BPH as a result of uncoordinated contraction of Prostata. BPH bladder muscle or impairment in the timing of bladder muscle contraction and urethral sphincter relaxation.
Certain medications can increase urination difficulties by increasing bladder outlet resistance due Prostata. BPH increased smooth muscle tone at the prostate or bladder neck and contribute to LUTS. Micrograph showing nodular Prostata. BPH left off center of the prostate from a transurethral resection of the prostate TURP. Normal non-neoplastic prostatic tissue NNT.
Benign prostatic hyperplasia. High-grade prostatic intraepithelial neoplasia. Prostatic adenocarcinoma PCA. Lifestyle alterations to address the symptoms of BPH include physical activity,  decreasing fluid intake before bedtime, moderating the consumption of alcohol and caffeine-containing products and following a timed voiding schedule.
Patients can also attempt to avoid products and medications with anticholinergic properties that may Prostata. BPH urinary retention symptoms of BPH, including antihistaminesdecongestantsopioidsand tricyclic antidepressants ; however, changes in medications should be done with input from a medical professional.
Voiding position when urinating may influence urodynamic parameters urinary flow rate, voiding time, and post-void residual volume. This urodynamic profile is associated with a lower risk of urologic complications, Prostata. BPH as cystitis and bladder stones.
They have a small to moderate benefit. Common side effects of alpha blockers include orthostatic hypotension a head rush or dizzy spell when standing up or stretchingejaculation changes, erectile dysfunction headaches, nasal Prostata.
BPH, and weakness. The older, broadly non-selective alpha blocker medications such as phenoxybenzamine are not recommended for control of BPH. Effects may take longer to appear than alpha blockers, but they persist for many years. Antimuscarinics such as tolterodine may also be used, especially in combination with alpha blockers.
Phosphodiesterase-5 inhibitors such as sildenafil citrate show some symptomatic relief, suggesting a possible common cause with erectile Prostata. BPH. Food and Drug Administration approved tadalafil to treat the signs and symptoms of benign prostatic hyperplasia, and for Prostata.
BPH treatment of BPH and erectile dysfunction EDwhen the conditions occur simultaneously. Intermittent urinary catheterization is used to relieve the bladder in people with urinary retention.
Self-catheterization is an option in BPH when it is difficult or impossible to completely empty the bladder. If medical treatment is not effective, surgery may be performed.
Surgical techniques Prostata. BPH include the following:. The latest alternative to surgical treatment is arterial embolizationan endovascular procedure performed in interventional radiology. While herbal remedies are commonly used, a review found them to be no better than placebo. The prostate gets larger in most men as they get older. Incidence rates increase from 3 cases per man-years at age 45—49 years, to 38 cases per man-years by the age of 75—79 years.
