Do you recommend a metabolic evaluation in a kidney transplant patient with no prior history of nephrolithiasis who is found to have donor derived kidney stones?  

Thanks for an interesting question. It would help if we knew the relevant donor medical history, such as dietary indiscretions or enteric hyperoxalutia, which would not be issues in the recipient. Since this information is typically not available, I would collect two 24-hour urinary supersaturation...
