What is Ureteropelvic Junction Obstruction?

Ureteropelvic junction (UPJ) obstruction is a blockage that occurs at the junction where the ureter attaches to the kidney. This can result in decreased urine flow and increased fluid pressure in the kidney.

Most cases of UPJ obstruction are congenital (meaning the person is born with it). According to the Urology Care Foundation, 1 in every 1,500 children is born with UPJ obstruction. While UPJ obstruction can develop in adults, it’s less common.

Not all cases of UPJ obstruction need to be treated. Treatments can include open surgery to less invasive procedures. Bottom line: If you have a UPJ obstruction, it’s essential to discuss your options with your doctors.

Our board-certified urologists can evaluate your case and discuss whether treatment is necessary and what options are available.
