Almost every adult person is aware thatsuch a pyelonephritis (inflammation of the kidneys). But very few people know that one of the causes of this disease is pyelonectasia of the kidneys. Pyeloelectasia of the kidneys is the pathway to pyelonephritis.
This term is applied to thosepathologies, when the renal pelvis is enlarged (a place to collect urine before going to the ureter in the bladder). By the vastness of pathological changes, the lesion can be bilateral (by the number of kidneys) or one-sided, when there is left-kidney pyeloectasia or pyeloectasia on the right.
Forms of pyelonectasia and the causes of it
In severity of the course of the disease, variousforms: light, medium and heavy. Depending on this, in parallel with the pelvis, kidney cups and ureter can be affected. This happens quite often when the disease progresses.
Pyeloelectasia of kidneys occurs with stagnation of urinein the pelvis (a bad outflow) or throw it back into the kidney (a counter reverse flow from the bladder). The causes of such pathological processes are divided into different groups:
- Congenital dynamic: phimosis, neurogenic disorders of the urethra, narrowing and constriction of various parts of the urethra.
- Congenital organic: anomalies in the development of the ureter, kidneys, the wall of the upper urinary tract.
- Purchased dynamic: diseases leading to a significant increase in urine, hormonal changes, inflammation of the kidneys, infectious processes, narrowing of the urethra of the acquired character, adenoma and other tumors of the prostate and urethra.
- Acquired organic: urolithiasis, tumors in different parts of the urinary system and neighboring organs, kidney failure, inflammation of the ureter and its narrowing of traumatic or inflammatory nature.
Symptoms and complications
The pyeloelectasia of the kidneys of symptoms practically does not give. There are only signs of the underlying disease, which was the reason for the expansion of pelvis, or already the consequences.
Complications of stagnant urine in the kidneys can be as follows:
- Pyelonephritis (inflammation of the kidneys).
Atrophy of the kidney tissue.
Functional deficiency of the kidneys.
Necrosis of the urinary tissue (sclerosis of the kidney).
Diagnosis of pyelonectasis
Pyloectasis of the kidneys in most casesis detected in the fetus during pregnancy of the woman or during the first year of the child's life during ultrasound (ultrasound). In girls, this renal damage is much less common than in boys. The main number of cases of enlargement of pelvis in children of congenital origin. Sometimes such a pathology occurs during the intensive growth of the body.
In adult patients, the onset of this ailmentis mainly due to overlapping of the ureter by the canal. Therefore, with urolithiasis or other predisposing factors for the occurrence of pyelonectasia, periodic ultrasound of the kidneys should be performed to avoid serious complications.
When carrying out an ultrasound examination, attention is drawn to the static size of the pelvis before and after urination, their considerable size (7mm or more) or its change over the last year.
In connection with the progression of the disease foradditional methods for its detection are used to determine the cause: urography (intravenous injection of contrast medium) and cystography (introduction of a contrast medium through a catheter into the bladder).
Treatment and prevention
Based on research, a specialist doctordetermines the tactics of treatment. The main step in the therapy of renal pyelonectasia is to eliminate the cause of this ailment. Many congenital anomalies are corrected surgically. To remove stones, if possible, use a conservative method, or if necessary, surgery. Great attention is paid to the prevention of inflammatory processes before and after treatment.
To avoid the formation of this pathology of the kidneysthe following measures exist: timely and full-fledged treatment of diseases of the genitourinary system, restriction of consumed liquid as necessary, adherence to recommendations and strict instructions for pregnancy.</ p>
