Lower Urinary Tract Symptoms In Men

Lower urinary tract infections are one of the most common ailments you can find in women, but what about men?

Lower urinary tract symptoms in men commonly appear after a certain age.

They are usually related to benign prostatic hyperplasia (BPH).

What are LUTS (lower urinary tract symptoms)?

Lower urinary tract symptoms (LUTS) are usually given other terms, such as prostatism or clinical benign prostatic hyperplasia.

There are many different causes of lower urinary tract symptoms in men.

Relating all of them to the function of the prostate is oversimplifying (2).

There are three main types of LUTS (3):

1) Storage LUTS: Also known as irritative symptoms (1). They are associated with an impaired capacity of the urinary bladder to store urine. Storage LUTS include:

  • urgency to urinate.

  • nocturia (waking up several times to urinate at night).

  • urgency urinary incontinence (having a sudden need to urinate).

2) Voiding LUTS: Also known as obstructive symptoms (1). They are associated with impairment of the normal flow of urine (voiding dysfunction). Voiding LUTS include :

  • urinary intermittency (A urinary stream that is not continuous).

  • slow urinary stream.

  • straining (feeling the need to force or push to urinate).

  • terminal dribble (constant drops following the main urinary stream).

3) Post-micturition LUTS: They are symptoms that appear after the patient has finished urinating. They include

  • post-micturition dribble (an involuntary loss of urine after the patient has finished passing urine).

  • the sensation of incomplete bladder emptying.

What can cause LUTS or lower urinary tract obstruction in men?

As mentioned, a significant cause of lower urinary tract symptoms in men is prostatic enlargement.

However, there are many potential causes of LUTS in men. The most important causes are as follows (2):

  • Benign prostatic hyperplasia (BPH): Prostate enlargement is associated with bladder outlet obstruction. Prolonged obstruction leads to changes in the detrusor muscle.

  • Overactive bladder: It is associated with prostate enlargement in men. However, diabetes might also be a leading cause. In this condition, the bladder pushes urine out at the wrong time leading to storage symptoms.

  • Infections of the lower urinary tract: In these cases, inflammation and irritation of the urinary tract lead to storage LUTS. Urinary tract infections in men need further investigation. This is as they are likely to be associated with underlying conditions.

  • Bacterial prostatitis: Prostatitis leads to inflammation and can increase prostate volume. The symptoms are similar to those found in cases of a urinary tract infection.

  • Neurogenic bladder: It is a lack of bladder control due to an impairment in brain centers, the spinal cord, or peripheral nerves.

  • Foreign bodies or calculus in the urethra: They obstruct the normal flow of urine and cause voiding symptoms. Irritative symptoms may appear in cases of overlapped infection of the urinary tract.

  • Prostate cancer and bladder tumors: they mainly cause voiding symptoms due to an obstruction in the flow of urine.

  • Certain drugs: Prescribed drugs, such as calcium channel blockers, might cause lower urinary tract symptoms.

How does the bladder work?

The urinary bladder is the organ of the human body that’s dedicated to storing urine. However, there’s an interconnection between the bladder and the brain to control this function.

Several nerves coming from the bladder send a signal to let us know when it is becoming full.

These signals are monitored and controlled by various circuits in the spinal cord and the brain.

As mentioned above, a dysfunction in the urinary bladder is another cause of symptoms in men.

There are many theories for why the urinary bladder stops working as it should. The most important are as follows:

  • Problems in the urothelium: The epithelial wall of the bladder has urothelial cells that react to chemicals in the urine. They also have pressure receptors that activate when the urinary bladder is full. When there’s a problem with these receptors, the function of the bladder is compromised. This results in overactive bladder symptoms (5).

  • A dysfunction in the smooth muscle: There are several muscles involved in the normal function of the urinary bladder. A malfunction in the detrusor muscle may lead to an exaggerated response when the bladder is not full (6).

  • A neurogenic problem: This results from an injury in any part of the central nervous system. In these cases, abnormal activation of the detrusor muscle leads to detrusor overactivity (6).

How are lower urinary tract symptoms diagnosed?

Not every case of LUTS is associated with benign prostatic hyperplasia. However, HPB should be considered.

Every cause of lower urinary tract symptoms in men is associated with a given combination of signs and symptoms.

After gathering data about the patient and their symptoms, a physical examination should be performed.

The doctor will examine the bladder and the existence of acute urinary retention or pelvic pain.

They will also look for phimosis or any leading sign of stenosis of the urinary tract. This may be done through a post-void residual urine, which shows how much urine is left in your bladder after voiding.

A digital rectal examination is essential to evaluate the volume and consistency of the prostate as well.

After this general examination, the physician might also include more specific evaluations.

For instance, patients who report nocturia should be examined for swelling in the lower extremities (2).

The American Urological Association are commend evaluating the presence of lower urinary tract symptoms in men according to the international prostate symptom score (7, 8).

Also known as IPSS, the International Prostate Symptom Score evaluates voiding symptoms. It consists of 7 different questions, each one with a severity score.

  • Mild symptoms are diagnosed with a score of 0 to 7.

  • Moderate symptoms correspond to a score of 8 to 19.

  • Severe symptoms are given a score of 20 to 35.

After examining the patient, doctors will have enough data to guide their diagnosis.

A dipstick test is essential to look for blood or glucose in the urine — leucocytes, or nitrites in urine that would point at an infection of the urinary tract. When renal impairment is considered, serum creatinine is also measured (2).

According to the National Institute for Health men should be evaluated with (PSA) only when their symptoms are suggestive of the following:

  • BPH.

  • In cases of abnormal digital rectal examination.

  • When the patient has a deep concern about prostate cancer (9).

How can you effectively manage lower urinary tract symptoms?

It is possible to improve the severity of lower urinary tract symptoms.

In any case, if patients do not adequately respond to the treatment, they should be referred to be managed by the urologist (7).


Depending on the cause of LUTS, there are several options to treat symptoms. They include:

  • Alpha-blockers: These medications are the first option in most cases of BPH.

    They help to relax the urethral smooth muscle, especially at the bladder neck.

    There are alpha-blockers such as tamsulosin, which are efficient in improving the symptoms. However, they can have a number of dangerous side effects.

  • 5 alpha-reductase inhibitors: These drugs are used in the treatment of BPH. They inhibit the enzyme that converts testosterone into its active counterpart in the prostate.

    Two examples of these drugs are finasteride and dutasteride. However, once again, it is essential to be aware of the side effects.

  • Phosphodiesterase inhibitors: An example is sildenafil, used to counter erectile dysfunction.

    Other examples include tadalafil and vardenafil. These drugs have been found to improve lower urinary tract symptoms in men, associated with BPH (benign prostatic hyperplasia) or not.

  • Antimuscarinic drugs: They are effective in reducing lower urinary tract symptoms associated with an overactive bladder.

    An example would be solifenacin and tolterodine. These drugs inhibit the activity of muscarinic receptors found in the detrusor muscle.

    Moreover, they reduce the exaggerated activation in this muscle that leads to bladder overactivity (13).

  • Beta-3 receptor agonists: When antimuscarinic drugs are not tolerated by patients with an overactive bladder, the second option is using beta-3 receptor agonists, such as mirabegron.

    They are only prescribed in patients with an antimuscarinic contraindication. They are effective and well-tolerated with no significant adverse events (14).

For men with BPH who do not respond to medical treatment, surgical interventions available. These include :

  • transurethral resection of the prostate.

  • laser surgery options such as greenlight photoselective vaporization of the prostate and holmium laser prostatectomy (2).

Lifestyle modifications

Some lifestyle modifications that would likely change the severity of the symptoms are as follows (2):

  • Decreasing the intake of alcoholic beverages, carbonated drinks, coffee, and caffeinated beverages.

  • Learning bladder training techniques in case of overactive bladder.

Natural treatments

Natural treatments are commonly used by many patients to improve their symptoms.

According to a systematic review and meta-analysis published in Cochrane Library, there’s a possible benefit in using ryegrass (Secale cereale) and African Red Stinkwood (Pygeum africanum).
