hydronephrosis (hydronephrosis transformation) - a progressive kidney disease, which is characterized by the expansion of its pelvis and cups, malnutrition (thinning), kidney tissue, and therefore violated all the basic functions of the kidney.Hydronephrosis is caused by violations of the outflow of urine from the renal pelvis and cups and is accompanied by a violation of blood circulation in the tissues of the kidney.Most often the disease occurs in women aged 25 to 35 years, as well as children
This disease is caused by the presence of some - any hindrance current urine.
There are congenital (primary) and secondary hydronephrosis.
congenital hydronephrosis develops as a consequence of any - any abnormalities of renal tissue, urinary tract and kidney in the presence of additional blood vessels.
Secondary or acquired hydronephrosis is due to complications of urological diseases: cancer of the ureter and renal pelvis, kidney tumor , traumatic injuries of the u
are three stages of hydronephrosis:
- urine starts to accumulate in the renal pelvis and pressure increase, it is stretched.On top of kidney function suffer quite significantly since the wall of the pelvis still able to keep her from overstretching.Gradually, however, its walls become thinner and more stretched pelvis.
- There is an expansion of the cups and the renal pelvis.Stretched pelvis pushes to compression of the renal tissue in the periphery.The thickness of the kidney tissue is greatly reduced due to its compression between a dense capsule of the kidney tissue and stretched wash basin.In this case the kidney function is already seriously impaired.
- Fabrics finally thinned and there is a sharp tissue atrophy kidney, its functions are plummeting, and subsequently disappear completely
In most cases, hydronephrosis develops asymptomatic and detected only by chance palpation abdominal X-ray or ultrasound, injury or outbreak.
specific symptoms, which can accurately differentiate hydronephrosis from other diseases - not.In this disease, the most frequently reported symptoms: seizures renal colic , aching pain in the lower back and kidneys of a continuing nature.Often there is hematuria (blood in urine).
Attacks are often accompanied by high blood pressure, abdominal distension, nausea and vomiting.As before the attacks, and during them, patients often marked decrease in the amount of urine and increase its opposite number after the attack.
in hypochondria clearly palpable tumor formation.
signs of renal failure occur for the most part only in bilateral hydronephrosis
The first treatment of this disease is aimed at eliminating the causes that caused the development of hydronephrosis, as well as the need to reduce the size of the pelvis.
Conservative treatment is used to reduce pain, lower blood pressure, relieve symptoms of renal failure, inflammatory processes and is used as a preparation for surgery.
methods of surgical treatment are quite a few, but the most common is the reconstruction of the renal - pelvis system.The amount and type of surgery depends on the disease, which is caused hydronephrosis.In recent years, quite a widely used laparoscopic treatment methods by which surgery is performed less traumatic way (punctures abdominal entered manipulators and an endoscope with a video camera).
To remove kidney resorted to only in the event that its function is completely lost, and its preservation can lead to dangerous consequences.
