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.
How do I know if my ureter is blocked?
Symptoms of a blocked ureter or urinary tract obstruction include:
- Pain in your abdomen, lower back or sides below your ribs (flank pain).
- Fever, nausea or vomiting.
- Difficulty urinating or emptying your bladder.
- Frequent urination.
- Recurring urinary tract infections (UTI).
- Urine that is bloody or cloudy.
What is a Megaureter?
Megaureter is an abnormality of one or both of the ureters of a child. Ureters are the two funnel-shaped tubes that carry urine from the kidneys to the bladder. A megaureter refers to an expanded or widened ureter that does not function normally.
How do you fix hydronephrosis?
Hydronephrosis is usually treated by addressing the underlying disease or cause, such as a kidney stone or infection. Some cases can be resolved without surgery. Infections can be treated with antibiotics. A kidney stone can pass through by itself or might be severe enough to require removal with surgery.
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 kidney stones affect your bowels?
However, sometimes kidney stones can cause gastrointestinal symptoms such as nausea, vomiting, and stomach discomfort. If you’re experiencing sudden low back pain and gastrointestinal discomfort, don’t ignore the possibility that it might be kidney stones.
Can kidney stones cause gas and constipation?
For those asking about kidney stone symptoms, I have had the following symptoms. Yes, you can experience severe/moderate/mild gas and bloating, and you can feel/be constipated.
How is Megaureter treated?
The typical surgery for megaureters involves putting the ureters back into the bladder (“ureteral reimplantation”) and trimming the widened ureter (“ureteral tapering”). If your child doesn’t have a urinary tract infection or decrease in kidney function, the surgery can be delayed until he/she is 12 months old.
How is Hydroureter diagnosed?
CT scan of the abdomen can be performed to evaluate the kidney anatomy and make the diagnosis of hydronephrosis. It also may allow the health care practitioner to look for the underlying cause including kidney stones or structures that are compressing the urinary collecting system.
Can constipation cause hydronephrosis?
Chronic constipation can lead to giant fecaloma threatening urinary tract patency, especially in older patients with immobility or dehydration. Therefore, clinicians should consider this condition as a rare but possible cause of hydronephrosis in older adult patients with chronic constipation.
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 obstructive megaureter a misnomer?
Obstructive megaureter is, in itself, a misnomer because most cases demonstrate only partial obstruction. Although this entity is rare, the principles of its evaluation and management may apply to a wide spectrum of ureteral abnormalities; consequently, a thorough understanding has a wide application.
What is the pathophysiology of primary megaureter obstruction?
Primary obstructing megaureter is caused by a structural alteration in the muscular layers of the distal ureter, which is characterized, to varying degrees, by diminished or absent longitudinal muscle fibers, hypertrophied or hyperplastic circular muscle fibers, or increased connective-tissue deposition.
What is a megaureter associated with?
A megaureter can be associated with the reverse flow of urine (vesicoureteral reflux, VUR). A megaureter can also be associated with an obstruction. The obstruction can either be the result of a ureterocele, or narrowing where the ureter meets the bladder (ureteral vesical junction obstruction).
