Megaureter is a medical anomaly whereby the ureter is abnormally dilated. Congenital megaureter is an uncommon condition which is more common in males, may be bilateral, and is often associated with other congenital anomalies. The cause is thought to be aperistalsis of the distal ureter, leading to dilatation. The cutoff value for megaureter is when it is wider than 6 or 7 mm.
In an attempt to improve communication and refine the understanding and the significance of megaureter, a working party of pediatric urologists was created. 5 They presented their findings and recommendations in 1976 at an international pediatric urologic seminar in Philadelphia. An agreement was made on standardization of nomenclature and classification of the megaureter.
Refluxing megaureter: In this type, the urine flows back up the ureter from the bladder. This backflow, known as vesicoureteral reflux, expands the ureter. Primary obstructed megaureter: The ureter is too narrow where it enters the bladder, causing a blockage of urine flow at that point.
Congenital megaureter An infantile ureter measuring more than 7 mm, visualized as a hyperintense tubular structure posterior to the bladder on T2W sequences is termed as a megaureter.( 13 ) It can be further classified as obstructed primary megaureter, refluxing primary megaureter (vesicoureteric reflux), and non-refluxing obstructed primary megaureter.( 13 ).
Valid for Submission. Q62.2 is a billable code used to specify a medical diagnosis of congenital megaureter. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code Q62.2 might also be used to specify conditions or terms like congenital dilatation of ureter, congenital obstructive megaureter, congenital obstructive megaureter without reflux.
What is a megaureter?A megaureter means “big ureter” and is a descriptive term, not a diagnosis. 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.
There is no history of abdominal surgery, trauma or other interventions. Differential diagnosis includes: congenital megaureter bilateral vesicoureteric reflux Considering appearance and age, finding most likely represent congenital megaurete.
Congenital giant megaureter: Introduction. Congenital giant megaureter: A rare condition where the patient is born with an abnormally dilated ureter. The anomaly is often associated with other defects or anomalies. The severity of the anomaly is variable.
SYN: megaloureter. primary m. independent ureteral dilation; may be nonobstructive or related to congenital distal ureteral obstruction. secondary m. hydroureter secondary to vesicoureteral reflux.
A birth defect, also known as a congenital disorder, is a condition present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional.

Refluxing primary megaureter is caused by a short or absent intravesical ureter, congenital paraureteric diverticulum, or other derangement of the vesicoureteral junction (, 20). Lee et al (, 21 ) assumed that the marked increase in collagen and significant decrease in smooth muscle could be major contributing factors in the pathogenesis of refluxing primary megaureter.
Megaureter is a medical anomaly whereby the ureter is abnormally dilated. Congenital megaureter is an uncommon condition which is more common in males, may be bilateral, and is often associated with other congenital anomalies. The cause is thought to be aperistalsis of the distal ureter, leading to dilatation. A functional obstruction at the lower end of the ureter leads to progressive.
