Horseshoe kidney is probably the most common renal fusion anomaly. Hor
seshoe kidneys have been successfully transplanted en bloc into a sing
le recipient or, alternatively, they have been divided and implanted i
nto 2 patients. Despite these facts the use of horseshoe kidney allogr
afts for transplantation is rare. We report a case of the successful t
ransplantation of an en bloc horseshoe kidney into a single recipient.
The evaluation of fused kidneys for transplantation, technical consid
erations and previously reported cases are discussed.
