Ureterovesical junction (UVJ) obstruction results when the flow of urine is restricted around the area where the ureter inserts into the bladder. UVJ often results in dilation of the ureter (megaureter) and may result in bladder problems and hydronephrosis (swelling of the kidney) if urine flow is obstructed. UVJ obstruction is 2-4 times more common in boys and slightly more common on the left side. Antibiotics are frequently used to prevent urinary infection until the cause of the swollen urinary tract can be clarified with imaging studies such as ultrasound. While some cases can result in kidney damage and are corrected with surgery, most UVJ obstructions go away on their own.
