A ureteropelvic junction obstruction, alternately called a UPJ obstruction or UPJO, occurs when there is a blockage in the urinary tract where the ureter, one of the tubes that carries urine to the bladder, connects to the kidney. While most cases of ureteropelvic junction obstruction occur in children and are diagnosed during prenatal ultrasounds or in early childhood, UPJ obstruction can occur in adults and older children due to scar tissue, infection, previous treatments for a blockage or kidney stones.
Ureteropelvic junction obstruction can cause a range of symptoms, and we recommend checking with your doctor if you experience any of the following:
- Abdominal pain
- Kidney stones
- Blood in urine, or hematuria
- High blood pressure
- Deterioration of kidney function
