[A familial form of nephrolithiasis in patients following kidney transplantation?]

Causes and mechanisms underlying nephrolithiasis after transplantation of the kidney differ much from known in other urological patients. We have found calculi in transplanted kidney in 5 of 939 surgical patients. Two cases of concrement formation in the transplant in the members of the same family aged 22 and 26 years we report as interesting. Our experience and literature data suggested family nature of the concrements. One of the patients underwent pyelolithotomy, the other impulse lithotripsy. Both the transplants function normally 5 years after kidney transplantation.
