Kidney hydronephrosis is a specific disease.
characterized by an abnormal increase in internal size
of the renal cup region due to the strong pressure on her
walls of a large volume of fluid (urine excreted by the kidneys). In this

Kidney hydronephrosis: what is it?
What is a kidney disease like
renal hydronephrosis is a serious pathology consisting in
increased content in both or one kidney fluid. Is broken

As a result of this, a partial may first arise, and then
with the progression of the disease, and complete renal

гидронефроз правой, так и левой kidneys. As for the bilateral
hydronephrosis, it is registered in 5-9% of detected cases.
Hydronephrosis can be not only congenital, but also acquired.
Moreover, congenital hydronephrosis occurs on the background
дискинезии мочевых путей, аномалии размещения почечной артерии
(possibly its branches), which squeezes the ureter.
Causes of hydronephrosis
The disease develops due to impairment or absolute
stopping the movement of urine from the kidney to the bladder, which
occurs due to a number of physiological or anatomical factors.
Additional renal vessel may cause disease,
passing to the bottom of the kidney from the aorta. This дополнительный сосуд
is located crosswise with the ureter and presses on it, that
leads to a narrowing.
A factor that provokes the development of kidney hydronephrosis becomes
an obstacle to the natural flow of urine from the body. This is due to
there can be any pathological process occurring as in a kidney,
and beyond – in nearby organs and tissues:
- stricture (narrowing) of the urinary tract,
- congenital or acquired;
- various stones in the genitourinary system;
- benign neoplasms;
- malignant tumors;
- retroperitoneal fibrosis.
As a result of urinary retention and expansion of the cups and renal pelvis
parenchyma and muscle fibers of the body atrophy. This leads to
deterioration of the kidney, until the complete loss of function.
Depending on the causes of the disease, it is distinguished
- Congenital – hydronephrosis develops in utero or immediately
- Acquired – hydronephrosis occurs due to lesions
ранее здоровой kidneys.
Acquired form of hydronephrosis may have as anatomical
causes of violation of urine outflow from the renal pelvis, and
physiological (arising on the background of central and
peripheral nervous system).
In total there are five main groups of pathological conditions,
creating mechanical anatomical obstacles in
- Thickening of the walls of the ureter or pelvis as a result
- The presence of tumors in the surrounding organs and tissues that
squeeze the ureter, kidney or urethra.
- Violation of the normal location of the ureter or kidney
(kidney prolapse, bending or torsion of the ureter).
- Overlap of the inner lumen of the ureter and pelvis
formed kidney stones.
- Squeezing or damage to the lower urinary organs
systems as a result of cancer and other diseases or
Quite often, women develop hydronephrosis during pregnancy.
It is caused by mechanical compression of the ureter and other
organs of the urinary system enlarged uterus.
Extent of the disease
Doctors share several degrees of development of this disease,
which have individual characteristics.

urine accumulation in the pelvis, a slight stretching of the walls of the pelvis,

Often the development of kidney hydronephrosis occurs imperceptibly.
The disease has no specific symptoms. In the early stages

As the pathology progresses, the patient complains about the following

- painful attack accompanied by nausea, in some cases –
- blood pressure rises;
- flatulence increases, the patient complains of discomfort due to
- with the penetration of infection in the kidney body temperature rises
– the most dangerous sign;
- there is blood in the urine – this applies to those patients who have
who are diagnosed with urolithiasis.
Hydronephrosis of the left kidney
Hydronephrosis of the left kidney является одним из самых частых
complications of urolithiasis, which can also manifest itself and
on right. Hydronephrosis of the left kidney повышает внутреннее давление
cups and pelvis. The walls of these bodies for some time “struggling” with
high pressure. Not sustaining pressure, pressure gradually
acts on the kidney itself, which in turn prevents the excretion of urine.
This process is capable of hitting the tissues of the left kidney. Tubules and
glomeruli atrophy and shrink. As a result, the layer is reduced

The first symptoms of urinary stagnation are: acute pain in the area

Symptoms in hydronephrosis of the left kidney:
- pain in the kidneys, aggravated to the damaged area;
- nervous overexcitement, anxiety;
- symptoms of intoxication with nitrogenous products – loss
appetite, dizziness, migraine, vomiting and nausea,
- pain in the back, which gives to the groin and under the shoulder blades;
- pain in the abdomen (stretching the walls of the ureter under
the size of the stone);
- small amount of urine excreted per day.
- A small amount of mucus and blood may also appear when
When late diagnosis, as well as unqualified

even to the complete loss of the ability to perform its functions.

Another possible outcome is urolithiasis, which can

Depending on the level at which the long-term

symptoms. The most common cause is urolithiasis.
Urinary stones that exceed natural size

completely or partially violate the outflow of urine.
Symptoms and signs:
- In the initial stage of the disease, the person usually complains of renal
colic; dull pain usually occurs in the evening

- Attacks may be caused by exercise or general
- The presence of blood in the urine is observed at elevated pressure in
cups, as well as the presence of kidney stones.
- Another characteristic feature is an increase in the kidney. In people with
asthenic physique she can even be palpable through
front wall of the abdomen.
Most cases of hydronephrosis (more than half) have
left-sided localization, in about 40% of cases pathology
affects the right kidney and only 5% of the hydronephrotic transformation
are bilateral in nature.
A dangerous complication of the hydronephrotic transformation is
renal failure and atrophy. Due to changes in tissues,
the kidney loses its functionality, and there comes a deadly
outcome from intoxication by exchange products.
Due to renal dysfunction, the blood content increases

removal of the affected organ, after which patients are given
hemodialysis procedures with an artificial kidney device or
transplant the organ from the donor.
During the examination, the doctor can pre-diagnose
hydronephrosis by palpation. In the area of the organ is observed
compaction. Also taken into account symptoms of the patient and the general
his state of health.
Ultrasound of the kidneys with hydronephrosis
For accurate diagnosis prescribed instrumental and
- urine and blood tests;
- Ultrasound of the kidneys;
- X-ray examination of the kidneys.
- If a результаты предыдущих обследований неоднозначны, пациент
may be referred to an MRI or CT scan.
Hardware diagnostics help determine and compare, with
which side there is, or kidney damage prevails. So
hydronephrosis of the right kidney has a larger size of the pelvis region according to
compared with a healthy left kidney. Or vice versa, left hydronephrosis
the kidney has a larger pelvis compared to the right kidney.

Treatment of renal hydronephrosis
The course of treatment, which will be selected by the doctor, has three directions:
relieving symptoms, eliminating the cause and reducing the load on
kidneys. The goal of treating hydronephrosis is to:
- remove accumulated urine and reduce its renal impairment
- prevent irreversible deformation;
- eliminate the cause of hydronephrosis.
Often the use of drugs precedes
the operation. Symptoms are eliminated at this stage.

pathological processes, such as foci of infection.
The doctor may prescribe drugs of the following steps:
- painkillers – to relieve pain
- antibiotics – if there are signs of infection in the body;
- средства, понижающие артериальное pressure;
- other medicines, depending on the patient
If a состояние почки в динамике ухудшается, то необходимо

There are two types of functions aimed at improving
- creating an additional channel for urine output,
- сужение расширенной чашечно-лоханочной системы kidneys.

restore the flow of urine and kidneys.
The following should be excluded from the daily diet.
- fried meat and spicy dishes.
Instead, the diet should include the following:

How to treat hydronephrosis folk remedies
Traditional methods recommend the use of additional
to the main drug treatment after consultation with the treating
a doctor. In this case, one kidney should be healthy.
Treatment of folk remedies involves the use of various
herbs and medicinal fees that improve kidney function and
facilitate the condition of patients with hydronephrosis. For this
- Pumpkin, namely, the stem. For the preparation of medicines
the stalks are crushed, filled with 500 ml of boiled water and
insist on a water bath for 20 minutes. After this infusion
must be removed, wrapped in a warm towel and infused for about 2
hours Take 4 times a day for half a glass at the reception.
- 150 gr. birch leaves, 50 g. nettle leaves, 50 g. herbs
adonis, 50 gr. grains of oats, 50 gr. bearberry and 50 gr. field
- In equal proportions take leaves of black currant, leaves
малины, корней аира, почечного чая, herbs череды, цветков
- Травы при гидронефрозе применяют в виде сборов,
It is recommended to use not longer than 3-4 months. Required
change fees, after each course after waiting for about 2 weeks. Infusions
plants take on an empty stomach, approximately half an hour before meals.
- Chopped parsley root, 1 tbsp. l., poured 100 ml
boiling water. The remedy is infused all night. Carefully drained in the morning
liquid and drink 1 tbsp. l on an empty stomach during the same day.

Kidney hydronephrosis, if acquired, occurs only when
certain conditions. Doctors recommend sticking with the following.
preventive measures to avoid its development:
- time to empty the bladder – frequent artificial
retention of urine may cause its part to be
splash back into the pelvis;
- to limit the use of salt and water – violation of salt and
water balance leads to excessive urine production in the kidneys;
- avoid hypothermia – this can trigger development
inflammatory processes in the urogenital system.
