Hello, I would be happy to help you with your question.
What you have is called 'hydronephrosis' and it is certainly more common on the right side because of the right-sided rotation of the uterus
. But if you actually had to have stents or nephrostomy
tubes last pregnancy, and you are having symptoms this pregnancy, then your next call should be to a Urologist
for immediate evaluation.
I hope that this helps and good luck - Please ask me if you have specific questions!
