Urinary disorders have many aspects: burning while urinating, frequent urge to go to the toilet, need to get up too often at night, abnormal color of urine, incontinence, difficulty urinating, etc. These symptoms correspond to a wide variety of diseases. Here are the main ones.

 prostate adenoma

It is also called BPH or benign prostatic hyperplasia. This is a prostate that has grown too much and which, pressing on the urethra, reduces its diameter. This causes many urinary disorders. This adenoma concerns men after 50 years and the frequency of these difficulties increases with age.

The disorders observed are: difficulty in urinating (need to push, decrease in the force of the jet, delay in starting the jet), urgency or the urgent need to urinate quickly, pollakiuria this very frequent need to urinate , nocturia, desire to urinate very often at night, late drops, and sometimes overflow incontinence, the bladder being too full sometimes tending to let out a little urine.


When diabetes begins, the body eliminates sugar in the urine. This can only be done with water. So, people with diabetes (especially type 1) and not yet on insulin urinate very large amounts. Very large sometimes means more than 10 liters per day! And the thirst is greatly increased as well. Once the diabetes is treated, these problems stop.

Subsequently, over the years, diabetes can lead to other urinary problems that often go unnoticed at first, as they occur gradually.

It is estimated that 40% of people with diabetes show some of these signs without reporting it to their doctor. This is due to damage to the nerves of the bladder which becomes overactive or underactive. Here are what these signs can be (although most people do not have all of them): a reduced feeling of the need to urinate, a weak urine stream, a delay in the start of the stream, a feeling of incomplete emptying after urinating, delayed drops, urinary urgency (need to urinate felt as urgent), frequent or rare urge to urinate.

On the other hand, people with diabetes are more prone to urinary tract infections.


Prostatitis is an infection of the prostate. There are 2 types of prostatitis which both cause urinary signs: acute prostatitis and chronic prostatitis.

  • In case of acute prostatitis, the man concerned has urinary signs of infection associated with fever. Here are these symptoms: difficulty urinating, burning while urinating, pain while urinating, a need to push to urinate. He may also suffer from strong and frequent urges to urinate, a weak stream. Sometimes, it may even become impossible for him to urinate.
  • In case of chronic prostatitis, urinary disorders are very diverse and depend on each man. These symptoms can be intermittent and can last for months and years. It can be burning while urinating, pain while urinating, a need to push to urinate. These signs are often associated with testicular pain or during ejaculation.


 Urinary tract infection

In men, urinary tract infections are rare because the urethra is much longer than in women, which protects it from the rise of bacteria from the outside into the bladder. However, they exist, if only because of “weakening” events or diseases (for example, the passage of a urinary catheter leads to the risk of infection, diabetes also).

In this case, there are urgent urges to urinate, burning while urinating, cloudy urine, sometimes blood in the urine... But in the event of associated fever, it is no longer a simple urinary infection, but a priori, of a prostatitis. Indeed, the infected prostate becomes inflammatory, which raises the temperature.


These rare hereditary genetic diseases are linked to an anomaly in a gene. They lead to a very particular sign: the urine turns port red or brown. But the coloring is not immediate, it generally appears half an hour to an hour after urination (act of urinating) after exposure to light. This can therefore go unnoticed!

This urine anomaly, porphyria, occurs in crises and is associated with very severe stomach aches, nausea or vomiting and episodes of diarrhea or constipation. It can also be associated with psychological or neurological disorders.

Neurological diseases

Many neurological diseases such as multiple sclerosis (MS), Parkinson's disease, strokes, etc. can cause urinary problems. Why ? Because the proper functioning of the bladder is controlled by the nervous system in the brain and spinal cord. Damage at any level can therefore lead to urinary difficulties, regardless of the neurological disease in question.

When the neurological damage is in the brain, the disorders observed are pollakiuria (very frequent urge to urinate), nocturia (need to urinate several times at night), urgency (or urgent urge to urinate ), or urinary incontinence (urinary leakage due to lack of control).

When the spinal cord is affected, the affected person may suffer from the same symptoms, sometimes with partial or complete urinary retention.

Note that urinary tract infections can also increase in frequency.

 kidney cancer

Kidney cancer often causes no symptoms. It is therefore discovered by ultrasound or by examinations.

That said, it can manifest as blood in the urine. This is why it is always essential to carry out a balance sheet in case of blood in the urine. This is all the more so since the bleeding in this case is often intermittent and completely painless. That's no reason to neglect it!

Thus kidney cancer can sometimes be detected early, which increases the chances of being treated more easily with the least possible sequelae.

 Urinary stones

When stones are found in the kidneys or urinary tract, abnormal signs appear. We can observe urinary signs such as very frequent urges to urinate (pollakiuria), burning while urinating, the presence of blood in the urine, infected urine (cloudy, strong-smelling), all associated with lower back pain often radiating to the genital area and often digestive disorders (nausea, vomiting, constipation). But sometimes there are calculations resulting in little or no signs.

 prostate cancer

Prostate cancer does not initially cause any particular signs. This is what testing is for. However, in some men it can cause urinary signs when it becomes a little larger.

These symptoms are as follows: a frequent need to urinate, especially at night, urgency (urge to urinate), difficulty starting or stopping urination, pain or burning when urinating, jet of urine weak or slow or even interrupted at times, a feeling of poorly emptied bladder after urinating, the presence of blood in the urine, a need to push to succeed in urinating, difficulty in starting to urinate, difficulty in control the bladder (incontinence).

This may be accompanied by non-urinary signs, in particular sexual signs (blood in the semen, painful ejaculation in particular).

However, nowadays, the diagnosis of prostate cancer is often made before all these signs appear.

It is especially after prostate surgery that a man can have urinary difficulties, especially at the beginning, before healing is complete. This is often stress urinary incontinence, but it is often transient. Sexual signs such as erectile dysfunction are often associated with it, at least initially.
