Pediatric Congenital Ureteropelvic Junction Obstruction

Key Points About Ureteropelvic Junction Obstruction

  • Ureteropelvic junction obstruction is a blockage in the area that connects the renal pelvis (part of the kidney) to one of the tubes (ureters) that move urine to the bladder.
  • Ureteropelvic junction obstruction generally occurs when a baby is still growing in the womb. This is called a congenital condition (present from birth).
  • The most severe cases of ureteropelvic junction obstruction may require surgery early in life, while many do not require early surgery.
  • The majority of cases do not require surgery at all, but do need to be checked up periodically until the obstruction has gone away.
  • Early diagnosis and treatment of ureteropelvic junction obstruction can help preserve future kidney function.
