Abstract:
A ureteric ring is a smooth, concentric ring-like narrowing occurring in the upper third of the ureter. It is nonobstructive and may be transient and bilateral. There is a slight female preponderance. They are seen in all age groups and are common in the neonate together with transient changes. A ureteric ring has a characteristic appearance and is believed to result from contraction of circular muscle.
