Donor-gifted allograft lithiasis: extracorporeal shockwave lithotripsy with over table module using the Lithostar Plus.

Allograft lithiasis is usually secondary. Donor-graft lithiasis is a rare cause and only 5 cases have been reported. We report 2 such cases which are the first in the live-related transplantation programme. The pressing need to increase the donor pool in developing countries, safety of therapy in graft lithiasis coupled with minimal estimated risk of lithiasis recurrence in the donor are the main justifications for accepting calculi bearing kidney for transplantation. The 2 cases underwent extracorporeal shockwave lithotripsy using the overhead table module of the Lithostar Plus. The technical ease of lithotripsy using an on-line ultrasound module in these 'ectopically' placed kidneys is discussed. The effect of shockwaves on allograft function was studied by a pre- and post-renal scan (99Tc-DTPA) and serum creatinine. No adverse effect of shockwave on allograft function was noted both on short- and long-term follow-up.
