In a child with ureteropelvic junction (UPJO) obstruction, part of a kidney is blocked. This blockage typically occurs at the renal pelvis, which is where the kidney attaches to one of the ureters (tube that carries urine from the kidney to the bladder). Because of this blockage, urine builds up and can damage the kidney.
Most of the time, UPJO obstruction is congenital, meaning that it is present at birth. About one in 1,500 children are born with this condition. The problem occurs during fetal development, and the cause is unknown.
