Hydronephrosis during pregnancy?

Has anyone had this? I’ve been having mild to severe right rib and shoulder blade pain since 24 weeks. The dr kept saying it was probably my gallbladder or the baby. Well on my ultrasound to check on baby (32 weeks) Thursday they took a look in the office at my gallbladder and kidneys and found my right kidney is severely dilated so I am awaiting my renal ultrasound at the hospital on Monday. Dr said depending on what they think I may need a stent? Has anyone had any experiences with this?
