Incomplete doubling of the kidney: what threatens its development and how to conduct appropriate treatment
Currently, incomplete kidney doubling is considered the most common form of pathological development of the urinary system. This disease, in fact, is not considered a disease and does not have its own signs, but it reveals a high tendency of the patient to defeat the kidneys with nephropathies of a chronic nature.
With the development of incomplete duplication there can be two variants of the course of pathology:
- The kidney receives nutrition from one artery and has two pelvic organs.
- Has only one pelvis, but at the same time two arteries that exit the aorta separately.
Causes of incomplete doubling
Incomplete doubling of the left or right kidney develops due to the formation of two infectious foci at once in the metanephrogenic blastema. A complete disconnection of the blastema is not formed, even despite the appearance of two cupping and pelvis systems at once - this is in connection with the preservation of the capsular covering of the organ.
Each half of the pathological organ has its own blood supply. Vessels of this organ can come out with a common pillar - so the separation is formed already near, near or near the sinus, or may depart directly from the aorta. Some arteries located inside, are able to move from one kidney to another - this is very important to consider when performing an organ resection.
Partial doubling is a kind of organ doubling, which is characterized by the structure and structure of the organ, when doubling of the vessels and the renal parenchyma is performed without the doubling of the pelvis. It turns out that the sine of the kidney is divided by a jumper from the parenchyma into two separate departments. This division provokes an increase in the size of the organ.
This is important! As a rule, incomplete organ doubling is not at all dangerous and does not imply any clinical conclusion, unlike the development of a full-fledged doubling. The only danger in this situation is the option, in which the cup-and-pelvis system is doubled, as well as the ureters. To establish the correct diagnosis, excretory urography is required.
Clinical picture of pathology
Incomplete doubling of both kidneys or one of them is manifested by doubling renal vessels and parenchyma, but not accompanied by a doubling of pelvis. Usually the upper part of the affected organ is smaller than the lower part.
Usually just two ureters of the double kidney are opened with holes directly into the bladder, occasionally there is a splitting of the ureter, which has one hole in the pelvic region and one trunk, in the upper part of it there is splitting and union with the pelvis. The ureters can split at different levels. If there are just two ureteral orifices on one side of the bladder, then the hole of the ureter of the pelvis located on top is fitted with the opening of the lower pelvis. Often the ureters are intertwined on their way - usually one - two times.
At the junction of the two ureters, constriction is formed, which in the place of their full fusion prevents normal urodynamics, even if the anatomical patency of this department is preserved. In general, the upper part of the right or left kidney suffers, which slows the continuous flow of fluid, therefore contributes to the development of hydronephrosis of the kidney and the formation of a chronic process of inflammation. If the duplicated kidney does not develop a pathological process, then clinical symptoms are not observed. In this regard, the disease is more often diagnosed accidentally.
Symptoms of development of pathology
Signs of incomplete doubling of the left kidney or right in children are mainly due to infection of the urinary canals - this process is considered an indication for a comprehensive examination.
A person with a diagnosis of incomplete kidney doubling can live a long life without complaints and health problems, and pathology is detected accidentally by ultrasound examination. Doubling affecting the ureters is more likely to cause vesicoureteral reflux due to inadequate functioning of the closure functions of the mouths. Reflux is usually realized in the lower part of the bifurcated kidney. The mouth of the ureter in the upper part of the organ narrows, and this provokes the formation of a cyst that drains into the lumen of the bladder and causes expansion of the ureter.
Diagnostic measures. Varieties and carrying out
Usually incomplete doubling of the kidney does not require special diagnosis. A complete doubling is detected after the onset of the development of the inflammation process. Any duplication can be easily detected by means of radiography or ultrasound.
Diagnosis of lesion is established based on the results obtained after cystoscopy, excretory urography, ultrasound. Excretory urography makes it possible to examine the work of each part of the doubled kidney, its anatomical and structural changes. An important role in the diagnostic process is played by ultrasound and computer tomography.
This is important! With obvious changes in one of the half of the kidney and the deterioration of its functions, retrograde pyelography is used.
Clinical studies indicate a high incidence of a variety of pathologies on the side opposite to the side of doubling the kidney. When doubling both kidneys is often diagnosed acquired or congenital pathology - dysplasia, hydronephrosis, etc.
Necessity and organization of treatment for incomplete doubling of
Treatment of a disease primarily involves the therapy of an acquired infectious process or pathology, such as urolithiasis or pyelonephritis. In itself, incomplete doubling is not a disease, but this pathology significantly increases the risk of inflammation. If the defeat of the double kidney acquires a chronic course and is difficult to treat, the doctor will prescribe a resection to the patient.
It is important to know that identifying an incomplete doubling of a given organ in a person is recommended to begin to follow a healthy lifestyle. It is imperative to prevent the influence of toxic factors on the body - this will require you to give up drinking alcohol and smoking.
The doctor also reviews medical therapy, paying special attention to the diet. It is important to remember that the kidney will function properly until it becomes difficult due to malnutrition and unfavorable living conditions.
It is mandatory to organize activities aimed at tempering the body, as well as gradually conduct physical training. Thus, a person can prevent many lesions and complications, which provokes a doubling of the kidney. A specialist can help to formulate a diet and a way of life.
