Had a robotic pyeloplasty to repair upj obstruction/narrowing about 6 months ago. Testing revealed no improvement in kidney function after surgery. My doctor then did laser surgery to remove possible scar tissue he thought had formed due to my previous surgery. That did not help either. I just found out I have nephroptosis (my kindey drops into my pelvic region while standing). I believe my renal function is 66/34. I am getting repeat testing in about 3 months. I have discomfort off/on daily but it is tolerable. I dread more surgery. Has anyone had a failed robotic pyeloplasty? My nephroptosis didn't come about until after my second surgery. Is that coincidense or could it have been a result of surgery?
