A ureterovesical junction obstruction (UVJ) in children occurs when the ureter (tube that drains urine from the kidney to the bladder) is blocked at the bladder.
Overview
What is a ureterovesical junction obstruction (UVJ) in children?
The ureterovesical junction is located where the ureter (tube that drains urine from the kidney to the bladder) meets the bladder.
Ureterovesical junction (UVJ) obstruction means that there is blockage in this area. Therefore, urine backs up into the ureters and into the kidneys – known as hydronephrosis – and causes swelling and associated problems.
