The ureter is dilated

The ureter is dilated's disease overview

Most children are born with normal urinary tract. But in some babies, the tube between the kidney and the bladder will be wider called the stretchy ureter, which can cause infection and block the urine. If not treated, this disease can cause serious kidney damage.

The urinary tract is like a water pipe system, with a special "tube" that allows water and salt to flow through them. The urinary tract is made up of 2 kidneys, 2 ureter, bladder and urethra. The kidney acts as a dialysis system to eliminate toxins and keep sugar, salt and minerals useful. Urine, waste, created in the kidneys and flow down the tubes from 25 - 30cm long called the ureter pouring into the bladder. The ureter has a diameter of 3 - 4mm, when stretching about 5mm, steadily from top to bottom except 3 narrow places: one at the connection of the ureter - the renal pelvis, one in the ureter crossing the pelvic bundle (where the ureter goes away across the upper waist) and one in the bladder wall. The bladder stretches or expands to store urine until it is ready to drain water by urinating. It also closed the pathway into the ureter so that the urine could not flow back into the kidneys. The urine duct from the bladder out of the body is called the urethra.

What is

What is the ureter?

The ureteric dilatation standard is when the ureter is 7mm wide, this may be the result due to the abnormalities of the ureter itself (primary) or the bladder is blocked (secondary). Different types of ureteric stretches are described below.

Causes of The ureter is dilated's disease

Although there are still many differences in studies of Causes of ureteral dilatation first -handed due to congestion, in general, the authors agree on the main issue that has caused a base. The disease is caused by the disorders of the organization that has made the end of the ureter unable to contract normally to push the urine into the bladder as usual, which has caused the consequence of stagnant urine and gradually gradually Gradually relax the ureter at the top.

Symptoms of The ureter is dilated's disease

Ureteral stretching usually does not cause any symptoms. In fact, many cases detect disease during an ultrasound of the fetus. When symptoms occur, they may vary between different people or the level of discomfort they cause. In some cases, the ureter is found when treating children with urinary tract infections. Symptoms may occur in such cases including fever, back pain or vomiting.

But today, due to the widespread use of ultrasound tests before birth, most fetuses have ureteric stretches detected when the hydronephrosis or urinary tract of the fetus has suffered from the fetus. Stretching.

Due to the ureteric stretching can cause serious infections or lead to kidney damage due to urine stasis, so this is a very serious disease. Extending the urinary tract may suggest congestion leading to urine stasis in the kidneys, but not always the same. In some cases, the ureter can not affect the kidneys. In addition, most patients with ureteric dilatation are found before birth without symptoms. It is important to check regularly to ensure that the ureteral dilatation does not affect the activity of the kidneys and causes problems later.

Depending on the degree of dilatation of the ureter and the corresponding renal tank, the ureter is divided into 4 degrees:

Degree A: Little ureteral stretch

Degree from the ureter and pelvic pelvis

Grade II: Stretching the entire ureter but still straight, slightly dilated the kidney.

Grade III: The ureter is both stretched and twisted, dilated the renal pelvis

Transmission route of The ureter is dilated's diseaseThe ureter is dilated

Ureteral disease is not infectious, so it is not possible to spread from patients to healthy people.

People at risk for The ureter is dilated's disease

Boys are more likely to have more ureteral stretching than girls.

Prevention of The ureter is dilated's disease

Currently, scientists have not yet found the prevention of ureteral stretching for the fetus. Therefore, in order to detect this condition early in the fetus, pregnant women should regularly attend a regular prenatal check -up for early detection and timely handling.

Diagnostic measures for The ureter is dilated's disease

Diagnosis of an aneurysm of primary ureter is caused by congestion:

Abdominal ultrasound: Ultrasound helps distinguish between ureter and pyelonephritis-nephrotic pathology, helping to assess the location and degree of the ureter as well as the radio of the radio renal tanks, assessing the thickness of the renal parenchyma thereby partly assessing the corresponding kidney function, helping to detect bladder defects.

Venous ureter (UIV): Helps to assess kidney function, determine the length and morphology of the ureter dilated, determine the dilatation of the renal pelvis, determine The length of the pathological ureter, the most typical image between the stretchy ureter and the shrinking is the root -shaped. However, in case of poor kidney function, the UIV shot

often do not give good images; In those cases, it is necessary to rely on renal scintigraphy with MTC99-DPTA or MTC99- DMSA.

urethra with urethra (cum: cystouretrographie mictionelle): This is a mandatory test to distinguish the cause of the ureter aneurysm is due to obstruction or pitch due to pavement Back to the ureter. However, according to many authors, if there is a reflux in the film, it is also necessary to be wary of the combination of congestion. In addition, the upstream bladder also helps to detect other diseases such as congenital urethra, bladder neurological syndrome, secondary ureter aneurysm ...

Renal scintigraphy with MTC99-DPTA or MTC99-DMSA: Take kidney images with radioactive isotopes while theur, this method is increasingly commonly used in the commonly used in the The birth disease of the kidneys in children, this method helps to supplement the UIV well in the case of monitoring the progression of the disease in the case of conservation treatment.

Whitaker test: When there is a clogged ureter-the pressure of the renal pelvis will increase if the fluid infusion is 10ml in a minute directly into the renal pelvis with the catheter Poking through the skin, or the pressure difference between the bladder and the renal pelvis when doing the test will be up to 22cm H2O (normally this difference is 15cm H2O).

The ureter is dilated's disease treatments

Treatment of ureteral stretch There are 2 ways:

Ureteral stretch surgery

If tests show urine obstruction or impaired kidney function, children may need surgery to overcome. Typical surgery for ureteral dilatation includes bringing the ureter back to the bladder ("regeneration of the ureter") and the expansion of the ureter ("narrowing the ureter"). If the child does not have a urinary tract infection or a reduced kidney function, surgery may be waiting until he is 12 months old. Infant surgery is very difficult and should be performed by surgeons with newborn surgery skills. Many children can use antibiotics until surgery to help protect from infection.

Most of the most symptoms of ureteric stretches are treated with open surgery. For ureteral dilatation, which is obstructed. For reflux ureter can be repaired. And for very wide stretchy ureter, it can be cut.

Endoscopic surgery

Endoscopic surgery is performed through thin tubes into the body through a small cut. The surgeon uses a special camera to see inside the body and use very small tools to perform surgery. Endoscopy to regenerate the ureter is difficult and requires a highly skilled endoscopic surgeon. After surgery

Some tests need to be performed after surgery a few weeks later to see the surgical results. The size of the ureter may not improve immediately after surgery, so it will need to be checked over time. Some problems that can arise from surgery are:

Bleeding

The ureter is clogged

Vesicoureteral reflux
