The ureter narrowing is congestion in one or both ureteral tubes that conduct urine from the kidney to the bladder. The ureter is a small tubular part and has a length of 25 - 30 cm. Characteristics of the anatomical structure of the ureter has three physiological narrow positions: the pyelonephration connection with the ureter, the ureter crossing the pelvic artery and the ureter poured into the bladder, finally the ureter site .
Ureteral stenosis can be cured. However, if left untreated, symptoms can progress quickly from mild - pain, fever and infection - to serious kidney function, blood infection and death. The ureter stenosis is quite common but due to being treated, serious complications are very rare.
Causes of Ureteral stenosis's disease
The ureter narrowing has many different causes, some of which are the congenital narrowing . They include:
Double ureter is a deformity with a larger kidney characteristic, including two kidney elements with two renal pelvis and two separate ureter. This common situation, appearing at birth, causing the two urinary tract to form on the same kidney. The second ureter may be normal or only partially developed. If the second ureter works abnormally, the urine may flow back into the kidneys and cause damage.
abnormalities of the ureter location connected to the bladder or kidney, clog the urine. The abnormal connection between the ureter and the kidneys (the junction of the ureter) can cause the kidneys to dilate and eventually stop working. This abnormal may be congenital or it can develop along with the growth of children, due to injuries or scars, or in some rare cases, developing from a tumor. The abnormal connection between the ureter and the bladder (the junction of the ureter) can cause the urine to flow back into the kidney.
The ureter. If the ureter is too narrow, it will not allow the urine to flow normally, a small bulge in the ureter can form and develop, usually occurs in the ureter near the bladder. This condition can block urine and cause urine to flow back into the kidneys, thereby leading to kidney damage.
Peritoneal fibrosis. This rare disorder occurs when the fiber tissue develops in the area behind the abdomen. The fibers may develop by cancer or may be used by some drugs used to treat migraine. The fibers surround and block the ureter, causing the urine to flow back into the kidneys.
Other reasons
Many reasons inside or outside the ureter can lead to ureter stenosis, including:
ureteral stones
Severe constipation, which occurs mainly in children but also occurs in adults
Cancer tumor and not cancer
Inner tissue growth, such as endometriosis in women
Swelling of the urinary tract, often due to diseases such as tuberculosis or parasites called Tapkin disease
Symptoms of Ureteral stenosis's disease
Ureteral stenosis may have no signs or symptoms, signs and symptoms depending on where the congestion occurs in part or the whole of the ureter pipe, how fast it grows and Does it affect one or both kidneys.
Signs and symptoms may include:
back pain
Change the amount of urine
Difficult to urinate
Bloody in urine
Urinary tract infections many times
Hypertension
When to see a doctor?
Patients should see a specialist in the urinary system if there are signs and symptoms that make the patient worried. Go to the medical facility immediately if any:
Pain so painful that cannot sit still or find a comfortable posture
Pain accompanied by nausea and vomiting
Pain accompanied by fever and chills
Bloody in urine
Urinary retention
complications
Ureteral stenosis can lead to infection of the urinary tract and non -recovery kidney damage.
Transmission route of Ureteral stenosis's diseaseUreteral stenosis
Ureteral stenosis is not infectious, so it is not possible to be transmitted from patients to healthy people.
People at risk for Ureteral stenosis's disease
People with ureteral stones
benign or malignant tumor in the ureter
Urinary tract infections
After surgical surgery in the ureter
Inflammation at the organs lying around the ureter. heavy constipation.
Excessive fetal fetal women cause the uterus to pinch the ureter. This has an effect on the two ureter at the same time.
Ovarian tumors appear, uterus, bladder, prostate, especially lymphoma or sarcoma.
Endometriosis.
Prevention of Ureteral stenosis's disease
Pregnant women should have a regular antenatal care to detect a child's congenital ureter narrowing and treat after birth. At the same time, check if the development of the fetus is inserted on the ureter of the pregnant woman.
Prevention of urinary tract stones. People should drink a lot of water so that the amount of urine is excreted at least 1.5 liters every day. If so, urine is always under saturated phase to avoid the risk of stone formation. It is necessary to avoid urinary tract infections, especially for women. The causes of urine stagnation must be resolved due to birth defects or suffering from other diseases in children as well as in adults. Should adjust the pH of urine depending on the type of stones that patients suffer from urine alkalinize in the event of cystin stones and uric acid, urine acidosis in the case of ammonium magnesium phosphate stones. For each type of disease, pay attention to eliminate causes that are favorable for the formation of stones such as diet to the adjustment of the physical and chemical factors of each patient, including cases. Essential surgery such as removal of adjacent tumors, shaping surgery to eliminate the causes of urinary tract stagnation.
Prevent constipation by a diet rich in fiber to help digestion and increase intestinal motility. Limit foods rich in fat, should eat on time to avoid digestive problems, should eat on time, especially the main meals such as lunch, dinner. Drinking plenty of water is a good habit of preventing constipation and bloating. Drink plenty of water along with a diet high in fiber to help the intestine circulate well, soft and easy to excrete. Exercise regularly with exercise helps the body to be healthy, prevent constipation, so the intestinal motility works well and is easily eliminated. Consuming a lot of probiotics helps the body prevent constipation, in addition to helping to regulate bacteria, the digestive system works well and boosts the body's immune system, prevention of gastrointestinal infections. Using natural enema has the properties of digestion, prevention of chronic constipation. It is aloe vera gel, papaya juice, pineapple juice, hot lemon juice, kiwi, flaxseed water ... Especially, bananas are fruits high in fiber to help the intestinal motility work well and are natural enema with natural enema effective. Going to the toilet when needed, should not stop urinating for a long time because it affects the digestive tract and can cause constipation, in addition to avoiding colitis.
Diagnostic measures for Ureteral stenosis's disease
Normally, doctors can detect and diagnose ureter stenosis before birth by ultrasound techniques, in addition to showing details of the development of the fetus, including the kidneys, the ureter and the ureter and bladder. Doctors often perform ultrasound after birth to re -evaluate the kidneys.
If the doctor suspects the ureter is narrow, some of the following tests and image techniques can be used for diagnosis:
Blood and urine tests. The doctor checks blood and urine samples to find signs of infection and the presence of creatinine, this index signals the function of the kidney.
ultrasound. Regional ultrasound on the back allows doctors to view kidneys and ureter.
Bladder X-rays when the urine issue (Vouching cystourethrogram). To check the abnormal urine flow, the doctor will insert a small tube through the urethra, inject the dye into the bladder and take X-ray, the ureter, the bladder and the urethra before and while urinating. /p>
Radoscope. A small tube with a camera and light is put into the urethra or through a small incision. The optical system allows the doctor to see inside the urethra and bladder.
Computerized tomography (CT). CT scan combines a range of X -ray viewing angles taken from different angles and processing computers to create a cross -sectional image of the kidney, ureter and bladder.
Magnetic resonance imaging (MRI). MRI abdominal area uses magnetic fields and radio waves to create detailed images of organs and tissues to create the urinary system.
Ureteral stenosis's disease treatments
The goal of treatment of ureter stenosis is to remove obstruction or ignore obstruction, which can help treat kidney damage. Treatment may include antibiotics to eliminate infections.
Drainage processures
The fierce pain of the ureter may require urine drainage immediately to remove urine from the body and temporarily reduce the problems caused by obstruction congestion. The doctor may appoint:
Place the ureter, an empty tube inserted inside the ureter to keep the ureter open and not narrow.
Percutaneous Nephrostomy (Percutaneous Nephrostomy) is to set up a urine drainage path from the pyelet to the skin through the skin, thereby solving the condition Solving local infections, limiting the possibility of widespread infections such as blood infections, prolonging the time of lifting the condition for patients to facilitate the resolution of the cause of obstruction. P>
A catheter is threaded through the urethra to connect the bladder to the external drainage bag. This may be especially important in the case of a bladder problem that also contributes to poor kidney flow.
urine drainage techniques can be temporarily or permanently indicated, depending on the condition of the patient.
Surgical surgery is indicated to treat obstruction causing ureter narrowing depending on the condition of the patient. Ureteral stenosis can be performed through one of the following methods:
Open surgery
Endoscopic surgery
The main difference between these surgical methods is the recovery time after surgery and the number, the size of the incision. The doctor will advise the patient the most appropriate surgical method to treat the disease.
