The article in brief
Urine is a key indicator of our health, revealing many potential pathologies. Here are the main signs of abnormality to look out for:
- Changes in colour and appearance haematuria, cloudy or frothy urine
- Urination problems : pollakiurianocturia, urgency
- Urinary volume abnormalities anuria, oliguria, polyuria
- Pain and difficulties burning, dysuria, pneumaturia
Urine is a mirror of our health. As an urologist, I see on a daily basis the importance of signs of urinary anomaly in the diagnosis of many pathologies. Here is a detailed overview of the symptoms to look out for and their potential significance.
Changes in the appearance and colour of urine
Red or pink urine
L'haematuriaor blood in the urine, is a major warning sign. It may be visible to the naked eye (macroscopic) or detectable only under the microscope (microscopic). In my practice, I have found that haematuria is the main symptom of bladder cancer, present in 90% of cases.
It is important to note that not all red urine is due to the presence of blood. Here is a summary table of possible causes:
| Urine appearance | Reaction to the strip | Possible cause |
|---|---|---|
| Red | Positive for blood, red blood cells present | Macroscopic haematuria |
| Red | Positive for blood, no red blood cells | Myoglobinuria or haemoglobinuria |
| Red | Blood negative | Coloration due to food or medication |
Other anomalies of colour and appearance
In the course of my career, I have observed various changes in the appearance of urine, each of which may indicate a specific problem:
- Cloudy, foul-smelling urine urinary tract infection: often a sign of urinary tract infection (pyuria)
- Frothy urine : may suggest abundant albuminuria
- Milky urine called chyluria, due to the presence of lymph
- Port-red urine after exposure to light Characteristics of porphyrinuria
These changes in appearance are valuable clues to the diagnosis. It is vital to consult a urologist as soon as these signs appear, to ensure rapid and appropriate treatment.
Urination disorders and urinary volume abnormalities
Symptoms related to urinary frequency
The signs of urine abnormality are not limited to their appearance. The frequency and rhythm of urination are also revealing. I recommend that my patients look out for the following signs:
Pollakiuria Urinary frequency: This is an increase in the frequency of urination, generally more than 6 times a day or an interval of less than 2 hours between each urination. This symptom may be the sign of a urinary infection or a prostate problem in men.
Nocturia If you get up more than once a night to urinate, this may indicate a urinary problem or a systemic pathology such as diabetes. I've often found that this symptom significantly alters my patients' quality of life.
Urgent care The urge to urinate, sometimes accompanied by leakage, may be a sign of an overactive bladder or a urinary tract infection. It requires a thorough assessment to determine the underlying cause.
Urinary volume abnormalities
The volume of urine produced in 24 hours is also an important indicator of urinary health. Here are the main cases:
- Anuria Diuresis of less than 100 ml/24h is a medical emergency which may indicate acute renal failure.
- Oliguria Urinary output of less than 300ml/24h may be a sign of dehydration or a kidney problem.
- Polyuria Diuresis in excess of 3 litres per 24 hours may suggest diabetes or excessive fluid intake.
In my practice, I have noticed that these volume abnormalities are often overlooked by patients, even though they may be indicative of serious pathologies requiring rapid treatment.
Pain and difficulty urinating
Painful or uncomfortable sensations during micturition are a symptom of signs of urine abnormality not to be overlooked. Here are the main symptoms I frequently encounter in my practice:
Burning while urinating
The burning sensation during urination is often suggestive of a urinary infection. However, it may also be due to inflammation of the urethra or certain sexually transmitted diseases. It is vital to seek medical advice as soon as possible to identify the cause and implement appropriate treatment.
Dysuria and other micturition difficulties
Dysuria is characterised by difficulty in urinating. It can manifest itself in various ways:
- Delayed urination
- Weak urinary stream
- Need to push on the abdomen to urinate
- Increased urination time
These symptoms may be a sign of an obstruction in the urinary tract, such as an enlarged prostate in men or a prolapsed prostate in women. In some cases, I have found that dysuria can also be neurological in origin.
The sensation of incomplete emptying of the bladder after micturition is another symptom to watch out for. It may be associated with dysuria and requires a thorough urological assessment.
Pneumaturia and other unusual signs
Pneumaturia, the emission of gas during urination, is a rare but worrying sign. It may indicate a fistula between the bladder and the intestine, requiring urgent surgical management. In the course of my career, I have had the opportunity to treat a number of cases of pneumaturia, and I can testify to the importance of early diagnosis in these situations.
The presence of clots in the urine is also a major warning sign, which may indicate significant haematuria or a urinary tract tumour. In these cases, immediate urological consultation is imperative.
Finally, the signs of urine abnormality are varied and can be indicative of a wide range of urological pathologies. Increased vigilance and prompt consultation in the event of unusual symptoms are essential for optimal care. Don't hesitate to consult a specialist if you have the slightest doubt, because in urology, as in many other medical fields, prevention and early diagnosis are your health's best allies.
