Kidney Stones: Causes, Symptoms, and Treatment Options #3236509 (License: Personal Use)

This educational diagram shows two human kidneys: one intact and healthy on the left, and one cut open on the right to reveal multiple white crystalline stones lodged in the renal pelvis and calyces. The surrounding vasculature-including the red renal artery, blue renal vein, and yellow ureter-is clearly labeled for anatomical context. The image highlights how stones form and obstruct urinary flow, potentially leading to pain and complications.
