@hshiffrin17 You're welcome! Having to have that surgery can be anxiety-producing, for sure. I also have a tumor on my right kidney that we are watching, and will face a nephrectomy if it gets aggressive or larger. My issue is my kidneys are at eGFR 22% now, so such a surgery will put me into dialysis immediately.

Please feel free to wander through this kidney and bladder group for information that may interest you. I will be curious what your son's dr may relate to him, about his kidney function going forward.
