The 5α-reductase inhibitors finasteride and dutasteride may also be used in men with BPH. These medications inhibit the 5α-reductase enzyme, which, in turn, inhibits production of DHT, a hormone responsible for enlarging the prostate. Effects may take longer to appear than alpha blockers, but they persist for many years. When used together with alpha blockers, no benefit was reported in short-term trials, but in a longer term study (3–4 years) there was a greater reduction in BPH progression to acute urinary retention and surgery than with either agent alone, especially in patients were more severe symptoms and larger prostates. Other trials have confirmed reductions in symptoms, within 6 months in one trial, an effect that was maintained after withdrawal of the alpha blocker. Side effects include decreased libido and ejaculatory or erectile dysfunction. The 5α-reductase inhibitors are contraindicated in pregnant women because of their teratogenicity due to interference with fetal testosterone metabolism, and as a precaution, pregnant women should not handle crushed or broken tablets.

Selective α-blockers are the most common choice for initial therapy. They include alfuzosin, doxazosin, silodosin, tamsulosin, and terazosin. They have a small to moderate benefit. All five are equally effective but have slightly different side effect profiles. Alpha blockers relax smooth muscle in the prostate and the bladder neck, thus decreasing the blockage of urine flow. Common side effects of alpha blockers include orthostatic hypotension (a head rush or dizzy spell when standing up or stretching), ejaculation changes, erectile dysfunction, headaches, nasal congestion, and weakness.

Tamsulosin and silodosin are selective α1 receptor blockers that preferentially bind to the α1A receptor in the prostate instead of the α1B receptor in the blood vessels. Less-selective α1 receptor blockers such as terazosin and doxazosin may lower blood pressure. The older, less selective α1-adrenergic blocker prazosin is not a first line choice for either high blood pressure or prostatic hyperplasia; it is a choice for patients who present with both problems at the same time. The older, broadly non-selective alpha blocker medications such as phenoxybenzamine are not recommended for control of BPH. Non-selective alpha blockers such as terazosin and doxazosin may also require slow dose adjustments as they can lower blood pressure and cause syncope (fainting) if the response to the medication is too strong.

Modification of predisposing factors can sometimes slow or reverse stone formation. Treatment varies by stone type, but, in general:

- Medication

- Surgery (lithotomy)

- Antibiotics and/or surgery for infections

- Medication

- Extracorporeal shock wave lithotripsy (ESWL) for removal of calculi

Most hormone dependent cancers become resistant to treatment after one to three years and resume growth despite hormone therapy. Previously considered "hormone-refractory prostate cancer" or "androgen-independent prostate cancer", the term castration-resistant has replaced "hormone refractory" because while they are no longer responsive to castration treatment (reduction of available androgen/testosterone/DHT by chemical or surgical means), these cancers still show reliance upon hormones for androgen receptor activation.

The cancer chemotherapic docetaxel has been used as treatment for CRPC with a median survival benefit of 2 to 3 months. A second-line chemotherapy treatment is cabazitaxel. A combination of bevacizumab, docetaxel, thalidomide and prednisone appears effective in the treatment of CRPC.

The immunotherapy treatment with sipuleucel-T in CRPC increases survival by 4 months. The second line hormonal therapy abiraterone increases survival by 4.6 months when compared to placebo. Enzalutamide is another second line hormonal agent with a 5-month survival advantage over placebo. Both abiraterone and enzalutamide are currently being tested in clinical trials in those with CRPC who have not previously received chemotherapy.

Only a subset of people respond to androgen signaling blocking drugs and certain cells with characteristics resembling stem cells remain unaffected. Therefore, the desire to improve outcome of people with CRPC has resulted in the claims of increasing doses further or combination therapy with synergistic androgen signaling blocking agents. But even these combination will not affect stem-like cells that do not exhibit androgen signaling. It is possible that for further advances, a combination of androgen signaling blocking agent with stem-like cell directed differentiation therapy drug would prove ideal.

Some current treatment options are:

- Non-invasive:

- For small stones, hydration, moist heat therapy, NSAIDs (nonsteroidal anti-inflammatory drugs) occasionally, and having the patient take any food or beverage that is bitter and/or sour. Sucking on citrus fruits, such as a lemon or orange, may increase salivation and promote spontaneous expulsion of the stone.

- Some stones may be massaged out by a specialist.

- Shock wave therapy (Extracorporeal shock wave lithotripsy).

- Minimally invasive:

- Sialendoscopy

- Surgical:

- An ENT or oral/maxillofacial surgeon may cannulate the duct to remove the stone (sialectomy).

- A surgeon may make a small incision near the stone to remove it.

- In some cases when stones continually reoccur the offending salivary duct is removed.

- Supporting treatment:

- To prevent infection while the stone is lodged in the duct, antibiotics are sometimes used.

Palliative care is medical care which focuses on treatment of symptoms of serious illness, like cancer, and improving quality of life. One of the goals of treatment in palliative care is symptom control rather than a cure of the underlying cancer. Pain is common in metastatic prostate cancer, and cancer pain related to bone metastases can be treated with bisphosphonates, medications such as opioids, and palliative radiation therapy to known metastases. Spinal cord compression can occur with metastases to the spine and can be treated with steroids, surgery, or radiation therapy. Other symptoms that can be addressed through palliative care include fatigue, delirium, lymphedema in the scrotum or penis, nausea, vomiting, and weight loss.

No treatment required. It is standard practice for men with infertility and category IV prostatitis to be given a trial of antibiotics and/or anti-inflammatories, although evidence of efficacy are weak. Since signs of asymptomatic prostatic inflammation may sometimes be associated with prostate cancer, this can be addressed by tests that assess the ratio of free-to-total PSA. The results of these tests were significantly different in prostate cancer and category IV prostatitis in one study.

Permanent stents are often metal coils, which are inserted into the male urethra. The braided mesh is designed to expand radially, applying constant gentle pressure to hold open the sections of the urethra that obstruct the flow of urine. The open, diamond-shape cell design of the stent allows the stent to eventually become embedded in the urethra, thus minimizing the risk for encrustation and migration. Permanent stents are used to relieve urinary obstructions secondary to benign prostatic hyperplasia (BPH), recurrent bulbar urethral stricture (RBUS), or detrusor external sphincter dyssynergia (DESD). The main motive for removal of permanent stents is worsening of symptoms even with device fitted. Other reasons have been migration, clot retention, hematuria, and urinary retention. The only FDA approved permanent stent is the Urolume. Usually, permanent stents are used only for men who are unwilling or unable to take medications or who are reluctant or unable to have surgery. Most doctors do not consider permanent stents a viable long-term treatment for most men.

Antibiotics are the first line of treatment in acute prostatitis. Antibiotics usually resolve acute prostatitis infections in a very short time, however a minimum of two to four weeks of therapy is recommended to eradicate the offending organism completely. Appropriate antibiotics should be used, based on the microbe causing the infection. Some antibiotics have very poor penetration of the prostatic capsule, others, such as ciprofloxacin, trimethoprim/sulfamethoxazole, and tetracyclines such as doxycycline penetrate prostatic tissue well. In acute prostatitis, penetration of the prostate is not as important as for category II because the intense inflammation disrupts the prostate-blood barrier. It is more important to choose a bactericidal antibiotic (kills bacteria, e.g., a fluoroquinolone antibiotic) rather than a bacteriostatic antibiotic (slows bacterial growth, e.g. tetracycline) for acute potentially life-threatening infections.

Severely ill patients may need hospitalization, while nontoxic patients can be treated at home with bed rest, analgesics, stool softeners, and hydration. Men with acute prostatitis complicated by urinary retention are best managed with a suprapubic catheter or intermittent catheterization. Lack of clinical response to antibiotics should raise the suspicion of an abscess and prompt an imaging study such as a transrectal ultrasound (TRUS).

A number of medications can be used to treat this disorder. Alpha blockers and/or antibiotics appear to be the most effective with NSAIDs such as ibuprofen providing lesser benefit.

- Treatment with antibiotics is controversial. Some have found benefits in symptoms while others have questioned the utility of a trial of antibiotics. Antibiotics are known to have anti-inflammatory properties and this has been suggested as an explanation for their partial efficacy in treating CPPS. Antibiotics such as fluoroquinolones, tetracyclines, and macrolides have direct anti-inflammatory properties in the absence of infection, blocking inflammatory chemical signals (cytokines) such as interleukin-1 (IL-1), interleukin-8 and tumor necrosis factor (TNF), which coincidentally are the same cytokines found to be elevated in the semen and EPS of men with chronic prostatitis.

- The effectiveness of alpha blockers (tamsulosin, alfuzosin) is questionable in men with CPPS. A 2006 meta-analysis found that they are moderately beneficial when the duration of therapy was at least 3 months.

- An estrogen reabsorption inhibitor such as mepartricin improves voiding, reduces urological pain and improves quality of life in patients with chronic non-bacterial prostatitis.

- Therapies that have not been properly evaluated in clinical trials although there is supportive anecdotal evidence include gabapentin, benzodiazepines, and amitriptyline.

In a small minority of cases of urethral syndrome, treatment with antibiotics is effective, which indicates that in some cases it may be caused by bacterial infection which does not show up in either urinalysis or urine culture. For chronic urethral syndrome, a long term, low-dose antibiotic treatment is given on a continuous basis or after intercourse each time if intercourse appears to trigger symptoms.

As low oestrogen may also be considered a source for urethral syndrome, hormone replacement therapy, and oral contraceptive pill (birth-control pills) containing oestrogen are also used to treat the symptoms of this condition in women.

Antibiotic therapy has to overcome the blood/prostate barrier that prevents many antibiotics from reaching levels that are higher than minimum inhibitory concentration. A blood-prostate barrier restricts cell and molecular movement across the rat ventral prostate epithelium. Treatment requires prolonged courses (4–8 weeks) of antibiotics that penetrate the prostate well. The fluoroquinolones, tetracyclines and macrolides have the best penetration. There have been contradictory findings regarding the penetrability of nitrofurantoin , quinolones (ciprofloxacin, levofloxacin), sulfas (Bactrim, Septra), doxycycline and macrolides (erythromycin, clarithromycin). This is particularly true for gram-positive infections.

In a review of multiple studies, Levofloxacin (Levaquin) was found to reach prostatic fluid concentrations 5.5 times higher than Ciprofloxacin, indicating a greater ability to penetrate the prostate.

Persistent infections may be helped in 80% of patients by the use of alpha blockers (tamsulosin (Flomax), alfuzosin), or long term low dose antibiotic therapy. Recurrent infections may be caused by inefficient urination (benign prostatic hypertrophy, neurogenic bladder), prostatic stones or a structural abnormality that acts as a reservoir for infection.

In theory, the ability of some strains of bacteria to form biofilms might be one factor amongst others to facilitate development of chronic bacterial prostatitis.

Escherichia coli extract and cranberry have a potentially preventive effect on the development of chronic bacterial prostatitis, while combining antibiotics with saw palmetto, lactobacillus sporogens and arbutin may lead to better treatment outcomes.

Bacteriophages hold promise as another potential treatment for chronic bacterial prostatatis.

The addition of prostate massage to courses of antibiotics was previously proposed as being beneficial and prostate massage may mechanically break up the biofilm and enhance the drainage of the prostate gland. However, in more recent trials, this was not shown to improve outcome compared to antibiotics alone.

Over time, the relapse rate is high, exceeding 50%. However, recent research indicates that combination therapies offer a better prognosis than antibiotics alone.

A 2007 study showed that repeated combination pharmacological therapy with antibacterial agents (ciprofloxacin/azithromycin), alpha-blockers (alfuzosin) and Serenoa repens extracts may eradicate infection in 83.9% of patients with clinical remission extending throughout a follow-up period of 30 months for 94% of these patients.

A 2014 study of 210 patients randomized into two treatment groups found that recurrence occurred within 2 months in 27.6% of the group using antibiotics alone (prulifloxacin 600 mg), but in only 7.8% of the group taking prulifloxacin in combination with Serenoa repens extract, Lactobacillus Sporogens and Arbutin.

Transurethral needle ablation of the prostate (TUNA) has been shown to be ineffective in trials.

Tamoxifen, a selective estrogen receptor modulator (SERM) with antiestrogenic actions in breast tissue and estrogenic actions in bone, has been found to be highly effective in preventing and reversing bicalutamide-induced gynecomastia in men. Moreover, in contrast to analogues (which also alleviate bicalutamide-induced gynecomastia), tamoxifen poses minimal risk of accelerated bone loss and osteoporosis. For reasons that are unclear, anastrozole, an aromatase inhibitor (or an inhibitor of estrogen biosynthesis), has been found to be much less effective in comparison to tamoxifen for treating bicalutamide-induced gynecomastia. A systematic review of -induced gynecomastia and breast tenderness concluded that tamoxifen (10–20 mg/day) and radiotherapy could effectively manage the side effect without relevant adverse effects, though with tamoxifen showing superior effectiveness. Surgical breast reduction may also be employed to correct bicalutamide-induced gynecomastia.

A method to treat ejaculatory duct obstruction is transurethral resection of the ejaculatory ducts (TURED). This operative procedure is relatively invasive, has some severe complications, and has led to natural pregnancies of their partners in approximately 20% of affected men. A disadvantage is the destruction of the valves at the openings of the ejaculatory ducts into the urethra such that urine may flow backwards into the seminal vesicles. Another, experimental approach is the recanalization of the ejaculatory ducts by transrectal or transurethral inserted balloon catheter. Though much less invasive and preserving the anatomy of the ejaculatory ducts, this procedure is probably not completely free of complications either and success rates are unknown. There is a clinical study currently ongoing to examine the success rate of recanalization of the ejaculatory ducts by means of balloon dilation.

Usually, affected men have a normal production of spermatozoa in their testicles, so that after spermatozoa were harvested directly from the testes e.g. by TESE, or the seminal vesicles (by needle aspiration) they and their partners are potentially candidates for some treatment options of assisted reproduction e.g. in-vitro fertilisation. Note that in this case, most of the treatment (e.g. ovarian stimulation and transvaginal oocyte retrieval) is transferred to the female partner.

HGPIN in isolation does not require treatment. In prostate biopsies it is not predictive of prostate cancer in one year if the prostate was well-sampled, i.e. if there were 8 or more cores.

The exact timing of repeat biopsies remains an area of controversy, as the time required for, and probability of HGPIN transformations to prostate cancer are not well understood.

IgG4-related disease responds well, and often dramatically, to glucocorticoid therapy, provided that advanced fibrotic lesions have not resulted in irreversible damage, and this has included resolution of radiologic findings. Men given glucocorticoids to treat IgG4-related disease at other anatomical sites sometimes report relief of their lower urinary tract symptoms, suggesting that IgG4-related prostatitis may be underdiagnosed.

Cases are however likely to get misdiagnosed as benign prostatic hyperplasia and to get treated alternatively with medications such as alpha blockers. The efficacy of alpha blockers in IgG4-related prostatitis remains unclear.

There are two types of prostatic stent: temporary and permanent.

Although a permanent prostatic stent is not a medical treatment, it falls under the classification of a surgical procedure. Placement of a permanent prostatic stent is carried out as an outpatient treatment under local, topical or spinal anesthesia and usually takes about 15–30 minutes.

A temporary prostatic stent can be inserted in a similar manner to a Foley catheter, requiring only topical anesthesia.

A number of medications exist to treat incontinence including: fesoterodine, tolterodine and oxybutynin. While a number appear to have a small benefit, the risk of side effects are a concern. For every ten or so people treated only one will become able to control their urine and all medication are of similar benefit.

Medications are not recommended for those with stress incontinence and are only recommended in those who have urge incontinence who do not improve with bladder training.

The most common side effects of bicalutamide monotherapy in men are breast pain/tenderness and gynecomastia. These side effects may occur in as many as 90% of men treated with bicalutamide monotherapy, but gynecomastia is generally reported to occur in 70 to 80% of patients. In the trial, at a median follow-up of 7.4 years, breast pain and gynecomastia respectively occurred in 73.6% and 68.8% of men treated with 150 mg/day bicalutamide monotherapy. In more than 90% of affected men, bicalutamide-related breast events are mild-to-moderate in severity. It is only rarely and in severe and extreme cases of gynecomastia that the proportions of the male breasts become so marked that they are comparable to those of women. In the trial, 16.8% of bicalutamide patients relative to 0.7% of controls withdrew from the study due to breast pain and/or gynecomastia. The incidence and severity of gynecomastia are higher with estrogens (e.g., diethylstilbestrol) than with like bicalutamide in the treatment of men with prostate cancer.

Surgery may be used to help stress or overflow incontinence. Common surgical techniques for stress incontinence include slings, tension-free vaginal tape, and bladder suspension among others. Urodynamic testing seems to confirm that surgical restoration of vault prolapse can cure motor urge incontinence. In those with problems following prostate surgery there is little evidence regarding the use of surgery.

The goals of the treatment for bone metastases include pain control, prevention and treatment of fractures, maintenance of patient function, and local tumor control. Treatment options are determined by multiple factors, including performance status, life expectancy, impact on quality of life, and overall status of clinical disease.

Pain management

The World Health Organization's pain ladder was designed for the management of cancer-associated pain, and mainly involves various strength of opioids. Mild pain or breakthrough pain may be treated with nonsteroidal anti-inflammatory drugs.

Other treatments include bisphosphonates, corticosteroids, radiotherapy, and radionucleotides.

Percutaneous osteoplasty involves the use of bone cement to reduce pain and improve mobility. In palliative therapy, the main options are external radiation and radiopharmaceuticals. High-intensity focused ultrasound (HIFU) has CE approval for palliative care for bone metastasis, though treatments are still in investigatory phases as more information is needed to study effectiveness in order to obtain full approval in countries such as the USA.

Thermal ablation techniques are increasingly being used in the palliative treatment of painful metastatic bone disease. Although the majority of patients experience complete or partial relief of pain following external radiation therapy, the effect is not immediate and has been shown in some studies to be transient in more than half of patients. For patients who are not eligible or do not respond to traditional therapies ( i.e. radiation therapy, chemotherapy, palliative surgery, bisphosphonates or analgesic medications), thermal ablation techniques have been explored as alternatives for pain reduction. Several multi-center clinical trials studying the efficacy of radiofrequency ablation in the treatment of moderate to severe pain in patients with metastatic bone disease have shown significant decreases in patient reported pain after treatment. These studies are limited, however, to patients with one or two metastatic sites; pain from multiple tumors can be difficult to localize for directed therapy. More recently, cryoablation has also been explored as a potentially effective alternative as the area of destruction created by this technique can be monitored more effectively by CT than radiofrequency ablation, a potential advantage when treating tumors adjacent to critical structures.

Monthly injections of radium-223 chloride (as Xofigo, formerly called Alpharadin) have

been approved by the FDA in May 2013 for castration-resistant prostate cancer (CRPC) with bone metastases.

A Cochrane review of calcitonin for the treatment of metastatic bone pain indicated no benefit in reduction of bone pain, complications, or quality of life.

If left untreated, complications may arise including abscess formation, peritonitis, sepsis, and damage to the urinary tract by fibrosis and granuloma formation. It is recommended, as a first step, to drain the lesion with ultrasound or CT guidance. If a patient has an underlying obstructive problem it needs to be addressed according to its cause.

Identifying and treatment the underlying malignancy constitutes an uptime approach. Topical 5-fluorouracil may occasionally be help, as may oral retinoids, topical steroids, vitamin A acid, urea, salicylic acid, podophyllotoxin, and cryodestruction employing liquid.
