Summary— Six cases of infection with Schistosoma haematobium complicating renal transplantation in patients from endemic areas have been found. In no case was the diagnosis made before operation; in 3 cases it was established by biopsy at the time of operation and in 3 cases it was established later. Three patients developed complications which appeared to be related to their schistosomiasis. In patients from endemic areas about to undergo renal transplantation, we suggest that pre‐operative and intra‐operative screening for schistosomiasis and other parasitic infections is advisable.
