What is ureteropelvic junction obstruction?

Also known as: UPJ obstruction.

The ureters connect the kidneys to the bladder and allow urine to pass through. When a blockage occurs where the kidney attaches to the ureter and prevents the flow of urine from the kidneys, this is known as ureteropelvic junction obstruction.
