Thanks for the reports. Sorry about the wait. I am having website problems. I was actually thinking you were sending a copy of the actual ultrasound scans. The reports work better. It looks like that mass is progressing. Not rapidly progressing but progressing nonetheless. I am not sure what type of prognosis they have given her, but I would imagine it would be anywhere from 3-6 months. If the left kidney looks completely normal on the ultrasound, it should be able to handle the load of the right kidney. The best way to measure that, though, would be to measure glomerular filtration rate (GFR) of the left kidney. That isn't a test that is easily done, though. It can usually be done only at a veterinary teaching hospital. If the GFR is low for the left kidney, then it probably cannot handle the full load, and putting the stent into the right kidney may help. If it is normal, it should be able to handle the full load. I am not sure of the availability of that test in your area, though, or the feasibility of getting it done. If not feasible, I would be hesitant to put the stent in if she was my dog, given the poor long term prognosis. I may be more likely to just keep her comfortable. If they think her expected life span is longer, though, and the left kidney is in really good shape, then I would do the surgery. I hope this makes sense. There is not really a right or wrong way to approach this, but it is a difficult decision. Please let me know if you have further concerns.
