Zapalenie gruczołu krokowego
Etiologia i przyczyny

Zapalenie gruczołu krokowego (prostatitis) obejmuje formy ostre i przewlekłe, zróżnicowane etiologicznie. Bakteryjne zapalenie prostaty, zarówno ostre, jak i przewlekłe, najczęściej wywołują bakterie Gram-ujemne z rodziny Enterobacteriaceae, głównie Escherichia coli (50-90% przypadków), a także Klebsiella, Proteus, Enterobacter, Serratia, Pseudomonas oraz bakterie Gram-dodatnie, takie jak Enterococcus (5-10%) i Staphylococcus. Drogi zakażenia obejmują wstępującą infekcję przez cewkę moczową, refluks zakażonego moczu do przewodów prostaty, rozprzestrzenianie się drogą limfatyczną lub krwionośną. Czynniki ryzyka to m.in. biopsja prostaty, cewnikowanie, przerost gruczołu, zaleganie moczu, kamica oraz osłabienie odporności. Przewlekłe bakteryjne zapalenie może wynikać z niepełnego wyleczenia ostrego stanu, z tworzeniem biofilmów bakteryjnych, szczególnie u pacjentów z kamicą prostaty.

Zapalenie gruczołu krokowego – Etiologia, przyczyny i czynniki wywołujące

Zapalenie gruczołu krokowego (prostatitis) to stan zapalny prostaty, który może przebiegać w formie ostrej lub przewlekłej. Przyczyny tego schorzenia są zróżnicowane i zależą od konkretnego typu zapalenia. W niektórych przypadkach przyczyną są zakażenia bakteryjne, w innych mechanizm powstawania nie jest do końca poznany.12

Etiologia bakteryjnego zapalenia gruczołu krokowego

Bakteryjne zapalenie gruczołu krokowego może występować w formie ostrej lub przewlekłej i jest spowodowane infekcją bakteryjną. W przypadku ostrego bakteryjnego zapalenia prostaty najczęstszymi patogenami są bakterie Gram-ujemne z rodziny Enterobacteriaceae, które odpowiadają za około 75-90% przypadków.34

Do głównych czynników etiologicznych bakteryjnego zapalenia prostaty należą:56

Większość infekcji prostaty (82%) jest spowodowana pojedynczym patogenem bakteryjnym, choć w niektórych przypadkach może być zaangażowanych dwa lub trzy szczepy bakterii.5

Drogi infekcji gruczołu krokowego

Bakterie mogą przedostawać się do prostaty kilkoma drogami:48

  • Wstępująca infekcja przez cewkę moczową
  • Refluks zakażonego moczu do przewodów prostaty
  • Bezpośrednie rozprzestrzenianie się lub droga limfatyczna z odbytnicy
  • Rozsiew bakterii drogą krwionośną z innych ognisk zakażenia w organizmie9

Czynniki ryzyka bakteryjnego zapalenia gruczołu krokowego

Zidentyfikowano szereg czynników zwiększających ryzyko rozwoju bakteryjnego zapalenia prostaty:1011

  • Zabiegi i procedury medyczne:
    • Biopsja prostaty (zwłaszcza przezodbytnicza)
    • Cewnikowanie pęcherza moczowego
    • Cystoskopia i inne manipulacje przezcewkowe
    • Zabiegi chirurgiczne w obrębie cewki moczowej12
  • Stany patologiczne układu moczowego:
    • Przerost gruczołu krokowego
    • Zaleganie moczu lub niedrożność dróg moczowych
    • Zwężenia cewki moczowej
    • Kamica prostaty lub pęcherza moczowego
    • Nawracające zakażenia układu moczowego (ZUM)13
  • Inne czynniki:
    • Niezabezpieczony stosunek analny
    • Stulejka i nadmiernie długi napletek
    • Urazy krocza
    • Określone grupy krwi
    • Osłabiony układ odpornościowy (np. HIV/AIDS)714

Etiologia przewlekłego zapalenia gruczołu krokowego

Przewlekłe bakteryjne zapalenie gruczołu krokowego najczęściej jest wywołane przez te same patogeny co ostre zapalenie. Może rozwinąć się, gdy leczenie ostrego zapalenia nie trwa wystarczająco długo lub nie eliminuje wszystkich bakterii.1 Bakterie mogą przetrwać w tkance prostaty, tworząc biofilmy lub rezerwuary infekcji, szczególnie u pacjentów z kamicą prostaty.615

Przewlekły ból miednicy mniejszej/Przewlekłe niebakteryjne zapalenie prostaty

Przewlekłe zapalenie gruczołu krokowego/zespół przewlekłego bólu miednicy (CP/CPPS) stanowi najczęstszą, ale najmniej zrozumianą formę zapalenia prostaty. Dokładna przyczyna tego stanu pozostaje nieznana, ale badania sugerują kilka możliwych czynników:216

  • Infekcyjne:
    • Mikroorganizmy inne niż bakterie (wirusy, grzyby)
    • Patogeny trudne do wykrycia standardowymi metodami
    • Nanobakterie i inne atypowe mikroorganizmy17
  • Immunologiczne i zapalne:
    • Odpowiedź immunologiczna na wcześniejsze zakażenie układu moczowego
    • Reakcja autoimmunologiczna
    • Dysfunkcja układu odpornościowego18
  • Neurologiczne:
    • Uszkodzenie nerwów w obszarze miednicy (po operacji lub urazie)
    • Zwiększona aktywność układu autonomicznego
    • Nieprawidłowa relaksacja zwieracza cewki moczowej i dyssynergiczne oddawanie moczu6
  • Inne czynniki:
    • Stres psychologiczny
    • Dysfunkcja mięśni dna miednicy
    • Refluks moczu do prostaty
    • Zaburzenia hormonalne1920

Bezobjawowe zapalenie gruczołu krokowego

Bezobjawowe zapalenie gruczołu krokowego nie powoduje objawów klinicznych i jest zwykle wykrywane przypadkowo podczas badań diagnozujących inne schorzenia. Przyczyna tego typu zapalenia pozostaje nieznana, choć w badaniach mikroskopowych stwierdza się obecność leukocytów w wydzielinie prostaty i nasieniu.121

Osoby z grupy szczególnego ryzyka

Szczególną uwagę należy zwrócić na pacjentów z obniżoną odpornością, którzy są bardziej narażeni na zakażenie atypowymi patogenami, takimi jak:227

  • Salmonella spp.
  • Mycobacterium spp.
  • Candida spp.
  • Cryptococcus spp.

Infekcje po manipulacjach przezcewkowych częściej wywoływane są przez Pseudomonas spp., które charakteryzują się wyższym poziomem oporności na cefalosporyny i karbapenemy.23

Powikłania zapalenia gruczołu krokowego

Nieleczone lub nieprawidłowo leczone zapalenie prostaty może prowadzić do poważnych powikłań, takich jak:2423

  • Ropień prostaty (występuje u 2,7% pacjentów z ostrym bakteryjnym zapaleniem prostaty)
  • Bakteriemia i posocznica
  • Zapalenie najądrzy i jąder
  • Niepłodność
  • Zaburzenia erekcji i dysfunkcje seksualne

Warto podkreślić, że zapalenie gruczołu krokowego nie jest bezpośrednio związane ze zwiększonym ryzykiem rozwoju raka prostaty, choć może powodować podwyższenie poziomu PSA, co komplikuje diagnostykę różnicową.2526

Aspekty epidemiologiczne zapalenia gruczołu krokowego

Zapalenie gruczołu krokowego jest najczęstszym problemem urologicznym u mężczyzn poniżej 50. roku życia oraz trzecim najczęstszym problemem urologicznym u mężczyzn powyżej 50. roku życia.24 Szacuje się, że około 8% mężczyzn doświadcza objawów zapalenia prostaty w ciągu swojego życia, jednak tylko około 10% z tych przypadków ma potwierdzoną etiologię bakteryjną.9

Zespół przewlekłego bólu miednicy (CP/CPPS) jest najczęstszą formą zapalenia prostaty, stanowiąc około 90-95% wszystkich przypadków. Ostre bakteryjne zapalenie prostaty jest najrzadsze, choć potencjalnie najpoważniejsze i wymaga natychmiastowego leczenia.2728

Zapalenie prostaty może wystąpić u mężczyzn w każdym wieku, ale najczęściej dotyka osób między 30. a 50. rokiem życia. Mężczyźni, którzy już wcześniej mieli zapalenie prostaty, są bardziej narażeni na ponowne zachorowanie.2930

Podsumowanie przyczyn zapalenia gruczołu krokowego

Etiologia zapalenia gruczołu krokowego jest złożona i zależy od typu schorzenia. Bakteryjne zapalenie prostaty jest najczęściej powodowane przez bakterie Gram-ujemne, głównie Escherichia coli. Drogi infekcji obejmują wstępującą infekcję przez cewkę moczową, refluks moczu do prostaty oraz rozsiew krwiopochodny.31

Patogeneza przewlekłego zapalenia gruczołu krokowego/zespołu przewlekłego bólu miednicy nie jest całkowicie wyjaśniona, ale prawdopodobnie jest wieloczynnikowa, obejmująca aspekty infekcyjne, immunologiczne, neurologiczne oraz psychologiczne.32

Dobrze rozpoznana etiologia danego przypadku zapalenia gruczołu krokowego ma kluczowe znaczenie dla wyboru odpowiedniej terapii i skutecznego leczenia pacjenta. Badania nad przyczynami zapalenia prostaty są kontynuowane, a nowe odkrycia mogą prowadzić do opracowania skuteczniejszych strategii leczenia i zapobiegania.2

    Prostatitis is a condition of the prostate gland most often linked with swelling and irritation, called inflammation. Bacterial infections cause some but not all prostatitis. […] Causes depend on the type of prostatitis. […] Acute bacterial prostatitis. Common strains of bacteria are most often the cause. The infection may have spread from other parts of the urinary or reproductive systems. […] Chronic bacterial prostatitis. This most often has the same cause as acute bacterial infection. It may happen when treatment for an acute infection isn’t long enough or fails to kill all the bacteria. […] Chronic prostatitis, also called chronic pelvic pain syndrome. Research suggests that the cause may involve several factors. These include an earlier infection, a condition of the nervous system or immune system, psychological stress, or issues with hormones. […] Asymptomatic inflammatory prostatitis. This has no known cause. It may show up during an exam for other medical conditions.

    https://www.niddk.nih.gov/health-information/urologic-diseases/prostate-problems/prostatitis-inflammation-prostate
    Prostatitis is a frequently painful condition that involves inflammation of the prostate and sometimes the areas around the prostate. […] The causes of prostatitis differ depending on the type. […] The exact cause of chronic prostatitis/chronic pelvic pain syndrome is unknown. Researchers believe a microorganism, though not a bacterial infection, may cause the condition. This type of prostatitis may relate to chemicals in the urine, the immune systems response to a previous urinary tract infection (UTI), or nerve damage in the pelvic area. […] A bacterial infection of the prostate causes bacterial prostatitis. The acute type happens suddenly and lasts a short time, while the chronic type develops slowly and lasts a long time, often years. The infection may occur when bacteria travel from the urethra into the prostate. […] Men with lower UTIs may be more likely to develop bacterial prostatitis. UTIs that recur or are difficult to treat may lead to chronic bacterial prostatitis. […] Researchers are currently seeking to better understand what causes prostatitis and develop prevention strategies.
  • #3 Acute Bacterial Prostatitis – StatPearls – NCBI Bookshelf
    https://www.ncbi.nlm.nih.gov/books/NBK459257/
    Bacterial prostatitis (BP) is most commonly caused by infection from members of the Enterobacteriaceae family, but organisms from other families can be responsible and are more likely in certain high-risk populations. Escherichia coli is the most common isolate from urine cultures and is the causative agent in the majority (approximately 50% to 90%) of cases. Other common isolates include the species Proteus, Klebsiella, Enterobacter, Serratia, and Pseudomonas. Gram-positive organisms such as Enterococcus species and Staphylococcus species and sexually transmitted organisms such as Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum are also sometimes implicated. Prostate manipulation from procedures such as transrectal prostate biopsy, transurethral prostate biopsy, cystoscopy, and catheterization appears to increase the risk of pseudomonas, mixed organisms, staphylococcal infections, and treatment failure prostatitis.
  • #4 Prostatitis: Background, Pathophysiology, Etiology
    https://emedicine.medscape.com/article/785418-overview
    Acute bacterial prostatitis may be caused by ascending infection through the urethra, refluxing urine into prostate ducts, or direct extension or lymphatic spread from the rectum. Approximately 80% of the pathogens are gram-negative organisms (eg, Escherichia coli, Enterobacter, Serratia, Pseudomonas, Enterococcus, and Proteus species). […] Chronic bacterial prostatitis may be due to the following: A primary voiding dysfunction problem, either structural or functional; E coli is responsible for 75-80% of chronic bacterial prostatitis cases. Enterococci and gram-negative aerobes such as Pseudomonas are usually isolated in the remainder of cases. […] The etiology of chronic prostatitis and chronic pelvic pain syndrome is poorly understood but may involve an infectious or inflammatory initiator that results in neurologic injury and pelvic floor dysfunction characterized by increased pelvic tone. […] The causes of asymptomatic inflammatory prostatitis are poorly understood.
  • #5 Acute Bacterial Prostatitis: Practice Essentials, Pathophysiology, Etiology
    https://emedicine.medscape.com/article/2002872-overview
    The organisms primarily responsible for acute bacterial prostatitis (ABP) are also those responsible for most urinary tract infections; these include gram-negative members of the Enterobacteriaceae family such as Escherichia coli, Proteus mirabilis, Klebsiella species, Enterobacter species, Pseudomonas aeruginosa, and Serratia species. Of these, E coli is involved most often and has been shown to increase biofilm formation. […] Most prostatic infections (82%) involve only a single bacterial organism. In some cases, two or three strains of bacteria may be involved. […] Obligate anaerobic bacteria and gram-positive bacteria other than enterococci rarely cause acute bacterial prostatitis. Enterococci account for 5-10% of documented prostate infections. […] Staphylococcus aureus infection due to prolonged catheterization may occur in the hospital. Other occasional causative organisms include Neisseria gonorrhoeae, Mycobacterium tuberculosis, Salmonella species, Clostridium species, and parasitic or mycotic organisms. N gonorrhoeae should be suspected in sexually active men younger than 35 years.
  • #6 Prostatitis – Genitourinary Disorders – Merck Manual Professional Edition
    https://www.merckmanuals.com/professional/genitourinary-disorders/benign-prostate-disease/prostatitis
    Prostatitis can be bacterial or, more commonly, nonbacterial. However, differentiating bacterial and nonbacterial causes can be difficult, particularly in chronic prostatitis. […] Bacterial prostatitis can be acute or chronic and is usually caused by typical urinary pathogens (eg, Klebsiella, Proteus, Escherichia coli) and possibly by Chlamydia. How these pathogens enter and infect the prostate is unknown. Chronic infections may be caused by sequestered bacteria that antibiotics have not eradicated, such as can happen in patients with prostatic calcifications. […] Nonbacterial prostatitis can be inflammatory or noninflammatory. The mechanism is unknown but may involve incomplete relaxation of the urinary sphincter and dyssynergic voiding. The resultant elevated urinary pressure may cause urine reflux into the prostate (triggering an inflammatory response) or increased pelvic autonomic activity leading to chronic pain without inflammation. […] Treatment varies significantly with etiology.
  • #7 Acute Bacterial Prostatitis: Diagnosis and Management | AAFP
    https://www.aafp.org/pubs/afp/issues/2016/0115/p114.html
    Acute bacterial prostatitis is an acute infection of the prostate gland that causes pelvic pain and urinary tract symptoms, such as dysuria, urinary frequency, and urinary retention, and may lead to systemic symptoms, such as fevers, chills, nausea, emesis, and malaise. […] Most cases of acute bacterial prostatitis are caused by ascending urethral infection or intraprostatic reflux and are facilitated by numerous risk factors. […] These infections may occur from direct inoculation after transrectal prostate biopsy and transurethral manipulations (e.g., catheterization and cystoscopy). […] In sexually active men, Neisseria gonorrhoeae and Chlamydia trachomatis should be considered. […] Patients who are immunocompromised (e.g., persons with human immunodeficiency virus) are more likely to have uncommon causes for prostatitis, such as Salmonella, Candida, and Cryptococcus species.
  • #8 Prostatitis: Causes, Symptoms, Diagnosis & Treatment
    https://my.clevelandclinic.org/health/diseases/15319-prostatitis
    Prostatitis is inflammation or infection in your prostate. It can cause pain in your abdomen, genitals or lower back, urinary problems or fever/chills. […] Different types of prostatitis have different causes. Sometimes the cause isnt known and other times its clear that the cause is a bacterial infection. […] Potential causes of bacterial forms of prostatitis include: Bladder infections or bladder stones. Sexually transmitted infections (STIs). Using a urinary catheter (tube that drains urine from your bladder). Having a prostate biopsy. Prostate stones. Urinary retention or urinary blockage. UTIs. Injury to your pelvic area. […] Its important to note that bacteria dont cause CPPS or nonbacterial prostatitis. […] The bacterial forms of prostatitis happen as a result of a bacterial infection. Bacteria can get in your prostate through your urethra or when your urine flows backward (vesicoureteral reflux).
  • #9 Acute Prostatitis: Symptoms, Causes, and Treatment
    https://patient.info/mens-health/acute-prostatitis
    Damage to the prostate makes it more prone to infection – for example, after prostate surgery. […] A thin, flexible, hollow tube (a catheter) passed into the bladder through the urethra may sometimes let bacteria travel to the prostate. This can also happen after a telescopic instrument is passed through the urethra into the bladder (as happens during investigation of the prostate gland and the bladder). […] Sometimes the prostate is infected by bacteria in the bloodstream that have travelled from other infections in the body. […] Acute prostatitis is not considered a sexually transmitted infection, so a sexual partner is not at risk. […] Symptoms of prostatitis affect around 8% of men at some point in their life, but only about 10% of these have a proven bacterial cause, though it is possible that more are bacterial but we never find out exactly which bacteria it is.
  • #10 Acute Bacterial Prostatitis: Practice Essentials, Pathophysiology, Etiology
    https://emedicine.medscape.com/article/2002872-overview
    If recurrent urinary tract infections are confirmed, patients need to be evaluated for any structural abnormality. […] Another source of acute prostatitis is following transrectal ultrasound-guided prostate needle biopsy. In this instance, the acute prostatitis is iatrogenic in nature but presents similarly and is treated as acute bacterial prostatitis. […] The following are risk factors for acute bacterial prostatitis (all allow bacterial colonization): Intraprostatic ductal reflux, Phimosis and redundant foreskin, Specific blood groups, Unprotected anal intercourse, Urinary tract infections, Acute epididymitis, Indwelling Foley catheter and condom catheter, Transurethral surgery, Altered prostatic secretions, Recent transrectal ultrasound-guided prostate needle biopsy. […] In the pediatric population, acute bacterial prostatitis has been associated with septicemic seeding, abnormal bladder dysfunction, congenital abnormalities of the ureter, and sexual abuse. A case report describes acute bacterial prostatitis in an adolescent after blunt trauma to the lower abdomen.

    https://www.mountsinai.org/health-library/diseases-conditions/prostatitis-bacterial
    Prostatitis is inflammation of the prostate gland. This problem can be caused by an infection with bacteria. However, this is not a common cause. […] Any bacteria that can cause a urinary tract infection can cause acute bacterial prostatitis. […] Infections spread through sexual contact can cause prostatitis. These include chlamydia and gonorrhea. […] In men over age 35 years, E coli and other common bacteria most often cause prostatitis. […] Acute prostatitis may also be caused by problems with the urethra or prostate, such as: Blockage that reduces or prevents the flow of urine out of the bladder, Foreskin of the penis that cannot be pulled back (phimosis), Injury to the area between the scrotum and anus (perineum), Urinary catheter, cystoscopy, or prostate biopsy (removing a piece of tissue to look for cancer). […] Men age 50 years or older who have an enlarged prostate have a higher risk for prostatitis. The prostate gland may become blocked. This makes it easier for bacteria to grow.

    https://www.roboticcancersurgery.com/contents/4-bacterial-prostatitis-risk-factors-to-know
    Bacterial infection of the prostate gland can have multiple causes, and not all of them are obvious. […] Bacterial prostatitis is caused by the infiltration of bacteria into the soft tissue of the prostate gland, thereby causing an infection. Multiple types of bacteria may cause prostate infections, including E. coli, Klebsiella, pseudomonas, and enterococcus. […] In most instances, an underlying reason leads to the development of bacterial prostatitis, found within four common risk factor categories. […] The first bacterial prostatitis risk factor category includes conditions that lead to lower urinary tract diseases such as enlarged prostate, incomplete bladder emptying, the presence of bladder stones, urethral strictures, and paralyzed bladder muscle conditions. […] The second inciting factor for bacterial prostatitis has to do with sexual activity. […] The third set of risk factors for bacterial prostatitis deals with lifestyle considerations. […] And the final set of conditions that may lead to bacterial prostatitis presents in individuals with recurring bowel health problems.
  • #14 Chronic Prostatitis: Causes, Symptoms, and Treatment
    https://patient.info/mens-health/prostate-and-urethra-problems/chronic-prostatitis
    Prostatitis means that you have inflammation of your prostate gland. There are two main types of prostatitis: short-lived (acute) or persistent (chronic). It can also be caused by an infection (infective) or be non-infective. Less than 1 in 10 cases of prostatitis are due to bacterial infection. […] The exact cause is often unknown and there may be several different causes or types of prostatitis. Chronic bacterial prostatitis is one possibility – caused by a persistent (chronic) infection with a germ (a bacterial infection). A man with chronic bacterial prostatitis will usually have had recurring urine infections. Chronic bacterial prostatitis is more common in men who have an immune system that doesn’t work properly (are immunocompromised) – this may be due to a disease, such as untreated HIV, or because they have a condition such as arthritis which needs to be treated with drugs that suppress the immune system.
  • #15 Chronic bacterial prostatitis – Wikipedia
    https://en.wikipedia.org/wiki/Chronic_bacterial_prostatitis
    Chronic bacterial prostatitis is thought to be caused by ascending urethral infection and by reflux into the ejaculatory duct or prostatic ducts. […] Risk factors for chronic bacterial prostatitis include functional or anatomic abnormalities, catheterization, prostate biopsy or urethritis (due to sexually transmitted infections), and unprotected penetrative anal sex. […] In theory, the ability of some strains of bacteria to form biofilms might be one of the factors that facilitate the development of chronic bacterial prostatitis. […] Recurrent infections may be caused by inefficient urination (benign prostatic hyperplasia, neurogenic bladder), prostatic stones, or a structural abnormality that acts as a reservoir for infection.
  • #16 Chronic prostatitis: Causes, symptoms, diagnosis, and treatment
    https://www.medicalnewstoday.com/articles/322457
    Chronic prostatitis refers to pain in the prostate that lasts at least 3 months. It happens due to inflammation of the prostate. Possible causes include bacterial infections and damage to the pelvic nerves. […] Prostatitis can be bacterial or nonbacterial. […] A bacterial infection of the prostate causes chronic bacterial prostatitis. It can result from various bacteria, such as Klebsiella, Proteus, or Escherichia coli, Chlamydia, or bacteria that remain despite antibiotic treatment for another infection, such as an acute prostate infection or urinary tract infection. […] Chronic non-bacterial prostatitis, or chronic pelvic pain syndrome, is a non-bacterial form of prostatitis that can have many causes and is harder to treat. It can occur when chronic pain persists after a previous prostate infection goes away, the urinary sphincter does not relax while emptying the bladder, nerve damage leads to overactivity in the pelvic nerves, damage to the urinary tract results from surgery or a physical injury, a person is facing psychological stress, or microorganisms other than bacteria infect the prostate gland.

    Prostatitis can be caused by bacteria that leak into the prostate gland from the urinary tract (the most common bacterial cause) and from direct extension or lymphatic spread from the rectum. […] It can also result from various sexually transmitted organisms such as Neisseria gonorrhoeae, Chlamydia trachomatis, or HIV. […] Other organisms responsible for infection are the same found most frequently in urinary tract infections, such as Escherichia coli. […] In many instances (especially in the chronic form of prostatitis), no specific cause of prostatitis can be found. […] Prostatitis can elevate the PSA level, which may require investigation or additional studies to rule our prostate cancer as a cause of the elevation. […] There is no evidence that prostatitis leads to prostate cancer. […] Prostatitis does not increase your risk of developing prostate cancer.

    Prostatitis is considered to be the most common urology problem for those under 50. […] Prostatitis is the inflammation of the prostate. […] There are three main types of prostatitis: Acute prostatitis – an infection of the prostate, symptoms come and go quickly. A rare but potentially serious form of the condition […] Chronic bacterial prostatitis – a persistent infection of the prostate, symptoms flare up over long periods of time […] Chronic prostatitis/chronic pelvic pain syndrome (CPPS) – similar to chronic bacterial prostatitis, but the cause is unknown. […] Bacteria that have travelled up the urethra to infect the prostate are the typical source of acute and chronic bacterial prostatitis. The cause of chronic prostatitis (CPPS) is unclear, although some studies have linked it to high levels of stress or depression.

    Prostatitis is an infection that exclusively affects males. A specific kind of bacterium which is responsible for causing STDs (sexually transmitted diseases) and urinary tract infections also causes prostatitis. Prostatitis is a common condition as approximately 50 percent of men are likely to experience it in their lifetimes. A weakened immune system and a clogged urethra are two fundamental causes of prostatitis. […] Acute prostatitis, on the other hand, is quite rare. Despite this, it is usually easy to diagnose because of some distinct characteristics. […] Our urologists strongly believe that majority of acute prostatitis cases can be treated effectively with antibiotics. Nevertheless, some patients may need to stay in a hospital for a short duration. There’s every possibility of an acute form of the condition turning chronic.

    Prostatitis can develop in men of all ages. […] Acute prostatitis is rare, but it can be serious and requires immediate treatment. It’s always caused by an infection. […] Chronic prostatitis is the most common type. It’s not usually caused by an infection. […] Risk factors for acute prostatitis include having a urinary tract infection (UTI) in the recent past, having an indwelling urinary catheter, having a prostate biopsy, having a sexually transmitted infection (STI), having HIV or AIDS, having a problem with your urinary tract, anal sex, and injuring your pelvis. […] Risk factors for chronic prostatitis include being middle-aged (30-50 years of age), having prostatitis in the past, frequent urine infections, if you have HIV or a problem with your immune system, and rarely it can occur as a result of a sexually transmitted infection. […] Chronic prostatitis can be challenging to treat because little is known about what causes it.

    Prostatitis is divided into categories based on cause. […] Two kinds of prostatitis, acute prostatitis and chronic bacterial prostatitis, are caused by infection of the prostate. […] Some kinds of prostatitis might be caused when the muscles of the pelvis or the bladder don’t work right. […] Sometimes prostatitis is caused by a sexually transmitted organism, such as chlamydia. However, most cases are caused by infections that are not sexually transmitted. These infections can’t be passed on to sexual partners. […] Men who have had prostatitis once are more likely to get it again. […] Prostatitis that is not caused by infection is often chronic.

    Prostatitis encompasses four distinct clinical entities, which can be described using the National Institutes of Health International Prostatitis Collaborative Network classification system. […] Acute bacterial prostatitis results from proliferation of bacteria within the prostate gland following intraprostatic reflux of urine infected with organisms such as Escherichia coli, Enterococcus and Proteus species. […] Chronic bacterial prostatitis (CBP) may result from ascending urethral infection, lymphogenous spread of rectal bacteria, hematogenous spread of bacteria from a remote source, undertreated acute bacterial prostatitis or recurrent urinary tract infection with prostatic reflux. Causative agents of CBP are similar to those of ABP include Gram negative rods, fungi, mycobacterium, Ureaplasma urealyticum, Chlamydia trachomatis and Trichomonas vaginalis. However, Escherichia coli is believed to be the causative organism in 75-80% of CBP cases. […] Unlike bacterial prostatitis where a causative organism can be identified, the aetiology of CP/CPPS is poorly understood; both inflammatory and infectious mechanisms have been postulated.

    Prostatitis reflects a broad spectrum of prostatic infections, both acute and chronic. […] Infection is often cited as the cause of this condition, despite frequent negative cultures. […] A genetic link or relationship to other diseases may prove to be part of the cause. […] Furthermore, a neurologic source, whether anatomic or psychologic, has been strongly debated. […] Ultimately, it may become clear that chronic prostatitis represents the final common result of a disease that originates from a cascade of multiple stimuli.
