My 14 year old son has been urinating blood for several weeks. The doctor ordered urine, blood tests and ultrasound of kidney and bladder. He has high EOS (7), high A/G ratio (2.7), WBC Esterase (trace abnormal), protein (1+), occult blood (3+), RBC (>30) and the ultrasound stated he has right kidney mild pelviectasis. They are recommending an referral to an Urologist and CT scan. What is mild right kidney pelviectasis?
Thank you
