I have a 6mm stone in my left upper ureter with mild hydronephrosis do I need surgery right away or is there a chance it could pass on its own with urine? What would you recommend?

A 6mm kidney stone in the ureter with mild hydronephrosis can sometimes pass on its own, but it's also possible it will require intervention. While some 6mm stones pass, a 6mm stone might be more likely to get stuck, causing pain and potentially requiring medical assistance. Hydronephrosis, the swelling of the kidney due to fluid buildup, can also be a reason to seek treatment
