question: hi.. i had my ultrasound yesterday and its says that "theres a moderate separation of pelveocalyceal system, bilateral. More pronounced on right side.", i want to know what does that mean, is it something serious? and what are the possible treatment for it. I had my ultrasound because im experiencing mild pains on my right side tummy. Last year, i was diagnosed to have kidney stone on my right kidney but it was treated with medicine. Im 24 years old, female, 52kgs in weight and 5ft in height, I hope to get help from you soon. Thanks in advance!
