To times theurine can appear with look different than usual: In some cases, a medical evaluation and other diagnostic tests are advised.
What are the altered aspects that the urine could present and when is it necessary to intervene?
The doctor talks about it Claudio Angelinihead of section of the nephrology and dialysis unit of Humanitas, in an article by Humanitas Health which we report below in full.
Light yellow urine
For centuries, urine color has been the only diagnostic tool for diseases of the urinary tract. Nowadays, even if there are many diagnostic tools, the analysis of the color and the aspect of urine remains a fundamental element for the diagnosis possible pathologies of the urinary system, namely the kidneys, ureters, bladder and urethra.
Urine usually has a yellow color more or less marked and appear clear. Different colors can appear during renal, urological or systemic pathologies and various degrees of turbidity are associated with the presence of suspended corpuscles. However, an alteration of these two parameters should not always be a cause for concern.
Strong-smelling dark urine
In the case, for example, where urine appears darker than normal and with a more intense smellit can also be dehydration or the result of a profuse sweating. In this case, the reintegration of liquids causes the urine to return to its usual color.
Another reason that can lead to dark colored urine is take certain medicationswhich result in pigmentation of the urine among the undesirable effects.
However, there could also be dark colored urine associated infections in this case announce cloudy and smelly appearance and the burning in the act of urinating. In severe cases, dark urine may indicate excess liver bilirubin or other substances such as muscle enzymes, or be a sign of malfunctioning parts of the urinary tract.
Red colored urine and blood in the urine
A reddish color urine can be a sign of hematuriait is the presence of blood in urine, a phenomenon that can have various causes. In case the blood in the urine is visible due to color, it is called macrohematuria, while when the presence of blood is not distinguishable with the naked eye, it is called microhematuria, and in this case the blood is only detectable by the physical examination chemical – urine.
For example, there is a special type of haematuria, called stress hematuriain which urine takes on a reddish color after a particularly intense physical effort, especially after the race. Also pelvic region trauma caused by contact sport can cause hematuria. However, blood in urine can come from any organ in the urinary tract and can occur in isolation or be associated with other symptoms such as abdominal pain or difficulty urinating.
Foam in urine
Foam in urine is a common occurrence: even in this case, it does not necessarily represent a health problem. Foam is formed, for example, as a result of rapid passage of urine, in case of dehydration or when there are residues of detergents in the toilet.
This phenomenon may be caused bytake certain medications and of urinary tract infections. If the problem persists or worsens, it could be an indicator of proteinuria or an abnormal presence of protein in the urine.
Altered urine: what to do?
In case of persistence of hematuria, dark urine or foam in the urine, in the absence of obvious effort, dehydration or taking new medications, it is advisable contact your doctor of confidence, which will evaluate the execution of physico-chemical examination of urine and of urine culturenecessary to assess the possible causes.
L’urine analysis it is a simple, non-invasive examination, which allows the early diagnosis of certain renal and urological diseases and must be inserted in each
In case of modification of the examination of thephysico-chemical examination of urine one will be useful specialized evaluation in nephrology / urology and the use of any other surveys, such as microscopic analysis of the urinary sediment, ultrasound of the urinary tract, specific blood tests and only in certain more serious cases the performance of second level tests (uro-CT or uroRMN) or kidney biopsy. Any laboratory modification should always be framed within the clinical context of each individual.
