Kidney pyeloelectasis in children: the main causes of

Anatomical abnormal expansion of renal pelvis is called renal pyeloectasia. Pyeloelectasia of kidneys in children is not an isolated disease, but merely an indirect sign that the patient has an outflow of urine from the pelvis, triggered by an infection or some kind of anomaly.

This disease is found in the fetus in the fetus or newborn, which indicates the inherent nature of the disease. This pathology is one-sided, if the kidney of the right kidney is disturbed in the child( the diagnosis is "pyloectasis of the right kidney in the newborn").When the neighboring pelvis is affected, then the left kidney pyeloectasia occurs in the child. Two-sided pyeloectasia occurs when both organs expand. This disease occurs more often in boys than in girls.

Detection of the disease in the newborn and fetus

In newborns, renal pyelonectasia is often congenital and can be associated with malformations of the fetus. This disease is mainly determined by conducting ultrasound in the period from 16 to 20 weeks of pregnancy.

This kind of congenital pathology of the urinary system can arise due to harmful effects on the fetus and the mother during pregnancy, as well as the genetic nature influences it.

Course of the disease without performing a surgical procedure.

This is important! Pyeloectasia has three forms: heavy, medium and light. Light forms do not require any treatment, but pass on their own. In many cases, pyelonectasia in newborns disappears after birth due to ripening of the urinary system. In some cases it is necessary to conduct conservative treatment, severe cases of the disease require an operation.

Causes of the appearance of pyeloectasia

With prolonged and increased pressure of urine in the kidney, which arises because of the presence of obstacles in the way of its outflow, stretching of the renal pelvis is observed. An impaired urine outflow can be triggered by increased pressure in the bladder, narrowing of the urinary tracts that lie below the pelvis, and also due to vesicoureteral reflux.

Causes of illness in infants and children:

Muscular weakness in newborns and prematurity;
With any abnormality of fetal development, ureteral circulation is caused by organs or large blood vessels, as well as the uneven growth of organs in young children and newborns;
Development of the fetus, in which the valve is formed in the region of the ureteric ureteral junction;
The child has a very rare urination, which causes a large outflow of urine, that is, the bladder is constantly full.

There is a left kidney pyeloectasia in a newborn, a right kidney and a lesion of both kidneys. With the expansion of pelvis and calyx, one can speak of a disease such as pyelocalikotectasia( hydronephrosis transformation of the kidneys).Expansion of the ureter and pelvis is called megaureter, ureteropyeloectasia or ureterohydronephrosis. Basically, pyeloectasia of the right and left kidneys is asymptomatic, it can be detected only when carrying out a special study. At the same time, when complications appear, characteristic symptoms will appear.

Causes of pieloectasia in adults:

A person takes a lot of fluids and the kidneys do not endure such a load;
With pyelonephritis and other inflammatory processes in the kidneys, the ureter can overlap with necrotic tissues or mucus, pus;
With urolithiasis, partial or complete obstruction of the ureteral lumen by concrement( stone);
Urinary system infections, provoked by the action of bacterial toxins on the cells of the ureters and pelvis;
Twisting or bending of the ureter, may occur with nephroptosis( wandering kidney) or with kidney depression;
Violation of the nervous supply of the bladder, which provokes an increased pressure in the bladder;
In elderly patients, the peristalsis of the ureters is decreased in bed patients.

Diagnosis of newborns.

This is important! If the child does not have severe pyelonectasia, regular ultrasound should be performed every 3 months. With the progression of the degree of pyeloectasia or the appearance of a urinary infection, a complete urological examination should be carried out, which should include: intravenous( excretory urography), radioisotope kidney cystography. These studies help determine the cause of the disease, the level and extent of the outflow of urine and choose treatment.

Diseases accompanying pyeloectasia

Pyeloectasia can accompany such diseases:

Ureterocele is a pathology in which the ureter enters the bladder and swells in the idea of a vesicle, and the way out of it narrows.
Megaureter - enlargement of the ureter.
Hydronephrosis, which is caused by obstruction( area of the tuberculosis-ureteral junction).There is a sharp widening of the pelvis, but the ureter does not expand;
Biliary ureteral reflux - the flow of urine occurs in the opposite direction.
Ectopic ureter - with this disease, the ureter enters the urethra( boys) or vagina( girls).
Valves for the posterior urethra. Detection of bilateral pyeloectasia on ultrasound, expansion of ureters.

What is the danger of pyeloectasia?

The causes that trigger the onset of pyeloectasia are a danger to human health. If a difficult outflow of urine is not eliminated on time, it leads to atrophy of the kidney tissue and compression of the kidney tissues, which, in time, provokes a decrease in kidney function or complete death.

Discharge of urine may be accompanied by chronic or acute pyelonephritis( bacterial inflammation of the kidney), which significantly worsens the kidneys and can lead to sclerosis of the kidney tissue.

This is important! If your child is diagnosed with pyeloectasia, you need to undergo a complete urological examination, find out the exact causes of the disease and correct them on time.

Treatment of a disease in children

The treatment of pyelonectasia in children depends on the cause of pyeloectasia and the severity of its course. With an average and not expressed degree of this disease, it is necessary to observe a qualified specialist and carry out treatment to reduce the degree of manifestation of manifestations or their disappearance.

The cases of surgical intervention

At the moment, specialists can not accurately state whether pyeloectasia will progress after the birth of the child. When a pregnant woman is observed and examined, the doctor decides whether to perform a surgical procedure.

In the case of progression of the disease, if there is a decrease in kidney function, a specialist can prescribe an operative intervention. In 25-40% of the disease, pyeloectasia requires surgical intervention.

How is surgery performed with pyeloectasia?

When performing a surgical procedure, eliminate vesicoureteral reflux and other obstructions. Some surgical interventions are performed endoscopically, using miniature instruments through the urethra.
