Megaureter is a medical anomaly whereby the ureter is abnormally dilated.
The cause is thought to be aperistalsis of the distal ureter, leading to dilatation.
[2] A functional obstruction at the lower end of the ureter leads to progressive dilatation and a tendency to infection.
[citation needed] Definitive surgical treatment involves refashioning the lower end of the affected ureter so that a tunnelled reimplantation into the bladder can be done to prevent reflux.
