So over the past couple of months Marlo has been having some pee problems. First was a bout of some diarrhea, a little bit of puking, and lots of water/peeing. U/A showed a minor infection, exam was normal except abdominal tenderness and blood work (cause I'm paranoid) was normal except slightly elevated creatinine. All was fine for a bit until we went away for 6 days (myself and my two dogs). Becky did fine but Marlo didn't deal with the trip very well: he was very stressed for most of the time.
Several days after getting back, I felt something wasn't quite right with him...and the vet thought a repeat U/A was a good idea anyways, so I sent some urine (my roommate works at a vet clinic and we're both techs although I don't work in the field right now). This time it came back SG high off the charts and blood, but no infection. The vet suspected interstitial cystitis and dehydration. We suspect that the poor guy wasn't drinking enough while we were away. Conveniently, my roommate is also good friends with the ultrasound tech that works in our town and so yesterday we u/s'd him on my coffee table
His bladder looked normal, his right kidney was fine but there's a large fluid filled cyst in his left kidney. The good news is that its not a tumour or polycystic kidney disease. The bad (ish) news is that no one seems to have really heard of or seen simple kidney cysts in dogs. The vet thinks that this accounts for the blood in his urine and his kidneys seem to be WORKING fine, but...I just want to know more! Has anyone seen this/heard of it? The vet is also not very concerned that it's going to be detrimental to his health but I'm a worried owner of course.
