Loss of Kidney

I had a vaginal hysterectomy Nov 2011.  I felt great after except for left sided pain that I was told was normal by my surgeon, then I was told it was muscle skelital pain at a later ER visit when the pain became worse.  I then had a bout of uncontrolled high blood pessure 200/100's which I already did have hypertension controlled by medication but my doc then increased my meds and added more, checked my renal arteries by ultrasound and I was told the ultrasound was fine.  Just recently during an MRI for some back pain the tech noticed I had severe problem with my left Kidney and got a picture and I followed up with my regular doc, now I have seen a nephrologist and a uroligist, after several more tests, days off work and a surgical proceedure I found out I have about 5% function in that kidney and it was caued by my ureter being cauterize or clamped during the hyster.  I also found out the ultrasound I had to look for renal artery stenosis during the first 6 weeks after my hyster did show I had some hydronephrosis then which I was never informed.  I don't want other women have this type of loss.  I don't want to have to "suck up" all the medical bills or lost time from work plus I travel out of town to see the urologist who would like to follow me closely as there is a mildly complex cyst in my right kidney.  Do I have any kind of case here
