In simple words: Megaureter is a birth defect where one or both of the tubes that carry urine from the kidneys to the bladder are wider than normal.

A congenital condition characterized by an abnormally dilated ureter. This dilatation is typically due to a developmental defect and can occur unilaterally or bilaterally.

Example 1: A newborn infant is found to have a dilated ureter on ultrasound during a prenatal checkup. Postnatal evaluation confirms the diagnosis of congenital megaureter., A toddler presents with recurrent urinary tract infections. Imaging studies reveal a significantly dilated ureter, leading to a diagnosis of congenital megaureter., A teenager undergoes imaging for abdominal pain and is incidentally found to have a mildly dilated ureter, consistent with congenital megaureter, which has remained asymptomatic until now.

Documentation should include imaging studies (such as ultrasound, VCUG, or CT scan) demonstrating the dilated ureter, as well as any associated findings like hydronephrosis or renal dysplasia.Details of the patient's clinical presentation, including any symptoms like urinary tract infections or abdominal pain, should also be documented.If surgical intervention is performed, operative reports and post-operative follow-up notes are essential.

** Congenital megaureter should be distinguished from other causes of ureteral dilatation, such as obstruction from a stone or tumor. It's important to accurately document the congenital nature of the condition to ensure appropriate coding and management.
