What does megaureter mean?

What does megaureter mean?

Megaureter is a ureter that is much wider than normal. The ureters are the tubes that carry urine from the kidneys to the bladder. A ureter that is wider than 3/8 inch is a megaureter. A megaureter may not drain urine normally. Urine may back up into the kidneys.

What causes megaureter?

This type is caused by a ureter that’s blocked and also suffers from reflux. This is dangerous, as the ureters get bigger and more blocked with time. People with this problem are more likely to get urinary tract infections.

What is a obstructive megaureter?

Introduction. Primary obstructive megaureter (POM) is one of the most commonly reported malformations of the urinary system in children. The term ‘Megaureter’ was introduced by Caulk in 1923 to describe a severe dilation of the distal ureter affecting a 32-year-old female.

Is megaureter congenital?

Congenital primary megaureter (PM) is an idiopathic condition in which the bladder and bladder outlet are normal but the ureter is dilated to some extent. It may be obstructed, refluxing or unobstructed and not refluxing.

What are the causes of bilateral hydronephrosis?

Bilateral hydronephrosis occurs when both kidneys are affected….Common causes of hydronephrosis include the following:

  • Kidney stones.
  • Urinary tract infections.
  • Congenital blockages.
  • Enlarged prostate.
  • Tumors or cancer (particularly cancers in the lower abdomen affecting the bladder, prostate, colon or cervix)

How do you fix a dilated ureter?

Most people with hydronephrosis will have a procedure called urinary catheterisation to drain the urine from their kidneys. Depending on the underlying cause, medication or surgery may be needed afterwards to correct the problem.

What is the cause of bilateral hydronephrosis?

Causes. Bilateral hydronephrosis occurs when urine is unable to drain from the kidney into the bladder. Hydronephrosis is not itself a disease. It occurs as a result of a problem that prevents urine from draining out of the kidneys, ureters, and bladder.

What is the difference between refluxing megaureter and obstructed megaureter?

If there is reflux, the diagnosis is “refluxing megaureter” or “megaureter from reflux”. If there is obstruction, the diagnosis is “obstructed megaureter” or “primary obstructed megaureter”. If there is neither reflux or obstruction, then the diagnosis is “primary non-obstructed megaureter”.

Is hydronephrosis associated with primary megaureter reflux?

There is associated hydronephrosis, and active peristaltic waves can be seen on ultrasound. In refluxing primary megaureter, vesicoureteric reflux is demonstrated (see vesicoureteric reflux (VUR) ) In non-refluxing unobstructed primary megaureter, there is absent or only a minor degree of hydronephrosis.

What are the two important questions about megaureter?

The two important questions about megaureter are whether there is reflux (backwash) of urine causing the megaureter or whether there is blockage at the ureterovesical junction causing megaureter (Figure 1). If there is reflux, the diagnosis is “refluxing megaureter” or “megaureter from reflux”.

What are the different types of megaureter?

In very rare circumstances, there can be reflux and obstruction and the diagnosis is “refluxing obstructed megaureter”. The two most common types of megaureter by far are the “primary non-obstructed megaureter” and the “refluxing megaureter”. Figure 1: Image of a ureterovesical junction obstruction.

What is primary megaureter?

Primary megaureter is a result of a functional or anatomical abnormality involving the ureterovesical junction (figure 1), whereas secondary megaureter results from abnormalities that involve the bladder or urethra (eg, myelomeningocele/neurogenic bladder, prune-belly syndrome, and posterior urethral valves).

Is megaureter common?

The two most common types are refluxing megaureter and primary non-obstructed, non-refluxing megaureter. Another class of megaureters is known as secondary megaureters. These are caused by health problems that include: A blockage in the male urethra.

What does it mean if a baby’s kidney is dilated?

Hydronephrosis in newborns is enlargement, or dilation, of the renal pelvis—the basin in the central part of the kidney where urine collects. Hydronephrosis can occur in one or both kidneys. This condition is often diagnosed before birth during a prenatal ultrasound.

How do I know if my ureter is blocked?

  1. Pain in your abdomen, lower back or sides below your ribs (flank pain).
  2. Fever, nausea or vomiting.
  3. Difficulty urinating or emptying your bladder.
  4. Frequent urination.
  5. Recurring urinary tract infections (UTI).
  6. Urine that is bloody or cloudy.

Can hydronephrosis go away on its own?

Although surgery is sometimes needed, hydronephrosis often resolves on its own. Mild to moderate hydronephrosis. Your doctor may opt for a wait-and-see approach to see if you get better on your own. Even so, your doctor may recommend preventive antibiotic therapy to lower the risk of urinary tract infections.

Can hydronephrosis be cured in babies?

Treatment often depends on the underlying cause. Although surgery is sometimes needed, in many cases hydronephrosis resolves on its own as a child grows, and surgery is not necessary. Essentially, hydronephrosis can be boiled down to a problem of urine flow.

Is fetal hydronephrosis genetic?

Minimal hydronephrosis is not genetic and is not hereditary. However, hydronephrosis may coincidentally occur in future pregnancies. If UPJ obstruction is determined to be the cause of the hydronephrosis, the chances for future children with the same obstruction may be as high as 50 percent.
