Renella: symptoms, duration and diet

The name renella suggests that this is something related to the kidneys, let's see if it is true by premising that it is a minor disorder of the urinary tract. Very often it is resolved by correcting one's diet and with a few tweaks you can avoid much suffering. It also has to do with thehydration which makes an important contribution in eliminating or preventing the formation of the annoying grit in the kidneys that causes gravel.

Renella: what it is

We often talk about kidney sand to define the gravel and it is a phrase that gives a good idea, I would say. It is not a serious or worrying disorder but it creates problems in the urinary tract where a sort of is formed sandstone consisting of a set of small sandy or granular stones. They are emitted during urination and not without causing discomfort and pain, as is to be expected.

Everyone can suffer from renella but the subjects most likely involved are those who are already prone to the appearance of urinary tract stones. There kidney sand it can take on different appearances, more than anything else it changes in color which can tend to be of two types: tending to reddish or whitish.

If the sand is reddish we speak of sediment brick, is formed by uric acid crystals and relative salts. If the sand tends to white instead, it is an accumulation of phosphates in the urine. In both cases the granules are much smaller than the sediments of another type, so much so that the presence of this sand can also be asymptomatic. It is not a reason not to take care of it because it could lead in the long run to the formation of real stones, very painful.

For this reason, what is recommended is to immediately adjust your diet and pay attention to how much we hydrate to avoid having to intervene when the renella it is no longer asymptomatic and may already have turned into something worse.

Renella: symptoms

In some cases, given the small size of the kidney sand, the granules come completely asymptomatic but this does not always happen. Sometimes these crystalline aggregates that make up the kidney sand and are formed in the kidneys, enter and channel into the excretory tracts causing pain when urinating or renal colic.

When it is not asymptomatic the renella have symptoms similar to those of kidney stones: abdominal or lower back pain often associated with nausea and vomiting. In the worst cases, the pain can radiate to the groin or genital area.

Pain is merely the consequence of the fact that i sand grains, of whatever color they are, they pass through the kidney channels, they can also cause burning during urination, in addition to pain. It is important to drink constantly as well as abundantly because in this way it facilitates its expulsion.

Where the kidneys and urinary system are located

The kidneys are bean-shaped organs located on the sides of the spine and therefore on the sides of our back, in the lower (lumbar) area. This is therefore the first area where we can feel the discomfort caused by the gravel.

The second area is instead that of our urinary system and in particular the bladder area, located in the pubic area.

In these two areas the gravel can therefore "pass with difficulty", causing us discomfort or pain.

Below is an image showing the location of the kidneys, the enlargement of a kidney and, in an anterior position, the bladder.

Renella: how long it lasts

There is no classic course of the renella which is a disorder of variable duration, not defined. As a rule, when the symptoms are very acute pains, they tend to be only temporary but if they are slow to pass, they can be gradually alleviated with the help of drugs. A proper diet however, it remains the best and most lasting remedy.

Renella: diet and natural remedies

At first it may seem that it is not enough to have a correct and balanced diet but once you start following it, the body will gradually settle down with its own times, so that expulsion occurs. Of course it depends from person to person and also from amount of sand already accumulated inside the kidneys. We try to drink at least two liters of water a day if we want there to be no delays.

When we talk about gravel diet we are not talking about a univocal and always valid diet, the indications are "personalized" and can also vary according to the type of sediments accumulated in the kidneys. For example, if the sand is mainly made up of calcium oxalates, foods rich in calcium should be reduced or eliminated. What does it mean? That we must eat less milk and dairy products, cocoa, eggs, tea and spinach. Otherwise if the granules that have accumulated are urate stones, serves reduce the intake of meat and alcoholic beverages, also avoiding beverages containing caffeine.

In both diets it is necessary to drink very regularly and throughout the day, even helping yourself with herbal teas, decoctions or infusions that favor the emission of sediments through the urine.

The elimination of gravel through the urine can be "slightly annoying" but not painful as the size of the granules are very small, unlike what happens for kidney stones.

Predisposition to Renella

An unbalanced diet is the main risk factor for gravel even though this disorder occurs in genetically predisposed individuals. Similarly predisposed subjects will be more prone to kidney stones.

The role of the type of water in the manifestation of the Renella

While numerous scientific studies show that an adequate supply of water prevents the manifestation of gravel, even in predisposed subjects, the thesis according to which the waters served by the city aqueducts of our country may be a cause of the gravel is completely devoid of scientific confirmation.

Rather, the intake of "hard" water and therefore with a higher concentration of calcium carbonate (such as the one we can drink from our sink) would seem to prevent gravel and stones more effectively than "soft" waters (such as those that can be bought in bottle).

Renella: drugs and tests

There are cases in which nutrition helps but is not enough, then one must contact one pharmacological therapy obviously hearing the doctor who is treating us for a diagnosis that will take place after having carried out the appropriate diagnostic investigations. The prescribed examinations they are usually theultrasound he blood and urine tests.

THE medications expected when the pains are acute are the same as those normally given for kidney stones. It is therefore about pain relievers is antispasmodics that go to reduce the painful sensation waiting for the diet to take effect.

Frequency of Renella cases in Italy

Grain is a disorder that affects 6-9% of the population in Italy, with frequent relapses. The new cases detected each year are about 100,000. (source: Manual of Urology, Francesco Porpiglia, Turin, Minerva Medica, 2015)

Grain occurs in a significantly higher percentage (150 to 300%) in males.

In addition to the aforementioned genetic predisposition and sex, i factors related to gravel I'm:

  • age
  • diet
  • body mass index (BMI)
  • place of birth (renella occurs with a higher incidence in more industrialized countries than in developing countries)
