uncertain diagnosis/ investigation for marathon runner

hiya, in my last exam there was a question that came up which I have been unable to find the answer for. It was something along these lines: 35yo marathon runner presents with severe RUQ pain. Urinalysis shows protein + blood +++ glucose -ve. What test would most likely confirm the diagnosis? Renal biopsy AXR Cystoscopy DMSA Renal US any ideas/ answers would be greatly appreciated! thanks
