You have not mentioned reasons of kidney blockage. Swelling of legs or edema can be due to kidney damage. If you have stones in the kidney, it can dilate ureter. These stones also damage kidney. Edema can be result of renal insufficiency.
My Right Kidney Is Blocked, The Ureters Are Dilated Does This Cause My Legs To Swell?
