How is the condition diagnosed?

> The healthcare provider will suspect a UPJ obstruction if the renal pelvis and kidneys are dilated. This dilation is known as hydronephrosis, and can be detected with a pregnancy ultrasound. It should be confirmed with another ultrasound after the baby is born.

Other diagnostic tests include:

Doppler ultrasound to measure the blood flow to the kidney

intravenous pyelogram, which allows the kidneys to be visualized under x-ray

renal scintigraphy, involves the injection of radio-nuclide tracer into a vein in the arm. The images produced from technique are helpful in assessing kidney function.
