Question: Megaureter

 mwalsh22 - Sun Apr 15, 2007 12:10 pm

I have an 11 year old son recently diagnosed with a megaureter. We took him to the hospital with abdominal pain that turned out to be constipation; however, through the CAT scan it was dtermined that he has this megaureter. He has been on antibiotics only twice in his life (each time for upper resp. infection). He has never had pain in back or while urinating. He has never had blood in urine. He has never had difficulty with urination. He has no indications of stones present. Is it possible that this has been here since birth? Although we have a VCUG and renal lasix exam scheduled, I am wondering if these tests are necessary as they are invasive and he will not be sedated. What are the risks is left alone? He has never complained of pain. The abdominal pain that he had was in the right lower quadrant and his megaureter is on the left side. The urologist on call stated that the pain he was at the hospital for was unrelated to the megaureter. I'm so confused!
Thanks for any help.

User avatar If only one side is effective this is very suspicious for a condition called ureteropelvic junction obstruction. Often this is a congenital condition but it can develop over time.

The risk of not diagnosing and treating this condition is that with this obstruction there is increased pressure in the ureter. This pressure causes the dilation. The pressure is also increased in the kidney and can cause kidney damage that can lead to high blood pressure and ultimately loss of the kidney.

Following up with the urologist and having the studies will be important.

Best wishes.
