A Bit Overwhelmed

I've been having some inflammation, fluid dysregulation and pain issues in my abdomen since my hysterectomy 15 months ago. Last week, primary care doc ordered an abdominal ultrasound which found a gallstone (Cholelithiasis. Adenomyomatosis.), lesions on my liver (hopefully nothing, MRI scheduled for next week), and moderate hydronephrosis with a 1.5cm shadowing calculus in the renal pelvis on my right kidney. Referred to urology (originally scheduled 6 weeks out, I pushed and got in this morning). Met with doc, who ordered a stat CT. Found out my right kidney is Duplex. 2.4cm x 1.4cm x 2.4cm in the UPJ causing moderate hydronephrosis. Also found a second large stone or cluster of stones, less hyperdense, in the lower pole measuring 2.5cm x 1.5cm x 1.3 cm. Awaiting for commentary from urologist, follow up appointment is Monday (today is Wednesday). I am completely new to this, but this situation seems like...a lot. No evidence of infection (yet). Any advice?? 41yo female. No insight on the condition of the ureters yet.
