Here's hoping everything is ok.

I also did some research, and I didn't know if you had already looked at this stuff too, but here you go:
Rabbits
Rabbits may develop several different types of renal disease.
Rabbits are prone to developing uroliths, especially if they havelimited exercise, are fed pellets and alfalfa free-choice, have beenover-supplemented with vitamins or minerals, or are obese. Rabbits withuroliths have the typical signs of kidney disease but may also havedifficulty urinating,
bloodin the urine, and may show pain through a hunchedposture and grinding of their teeth. A
urinaryobstruction is a medical emergency and the rabbitshould be seen by a veterinarian immediately.
Kidney failure can occur in rabbits, and be due to many causes including:
Infections including pyelonephritis, an inflammation of the kidney, often due to a bacterial infection
High blood calcium levels, often due to poor diet
Calcification ofthe kidney, resulting from excessive levels of vitamin D
Fatty degeneration in overweight rabbits
Cancer,especially lymphosarcoma
Rabbits with chronic renal failure often develop
anemia.
Encephalitozooncuniculi is a parasite that is transmitted through the urine, isingested, and moves from the intestines to the kidneys, brain, andother organs. It most commonly causes neurological signs such as a
headtilt or
paralysis, but itcan also cause chronic renal disease. There is a blood test forantibodies to
E. cuniculi that can determine whether a rabbithas been exposed. Unfortunately, a positive test is not diagnosticsince many (up to 80%) of rabbits may test positive for this parasite.There is no specific treatment for infection with
E. cuniculi.In addition to supportive care,
corticosteroidsmay be given to reduce inflammation.
Some drugs, especially certain
antibiotics suchas
gentamicin,can cause renal toxicity in rabbits, with the typical signs of kidneydisease.
Renal cysts are an inherited condition in rabbits, but usually do not cause illness.
