'''Megaureter''' is a medical anomaly whereby the [[ureter]] is abnormally [[wikt:dilate|dilated]]. [[Congenital disorder|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. <br />
<br />
The [[cutoff (value)|cutoff]] value for megaureter is when it is wider than 6<ref>{{cite web|url=http://www2.medizin.uni-greifswald.de/ki_chir/1/spectrum-of-care/thoracic-surgery/enlarged-ureter/|title=Enlarged ureter|website=[[Greifswald Medical School]]|accessdate=2017-02-06}}</ref> or 7 mm.<ref>[https://books.google.com/books?id=3XWKCwAAQBAJ&pg=PA140 Page 140] in: {{cite book|title=Diagnostic Imaging: Genitourinary E-Book.

<br />
A functional obstruction at the lower end of the ureter leads to progressive dilatation and a tendency to [[infection]]. The ureteric orifice appears normal and a ureteric [[catheter]] passes easily.<br />
<br />
Definitive [[surgery|surgical treatment]] involves refashioning the lower end of the affected ureter so that a tunnelled reimplantation into the [[Urinary bladder|bladder]] can be done to prevent reflux.<br />
