Case   Report:   During   regular   dissection   of   a   male   cadaver,   after   dissection   of   the   retroperitoneal   region,   it   was   observed   an   abnormal   conformation   of   the right   kidney:   it   was   completely   divided   by   a   fibrous   septum   into   two   lobes.   The   fibrous   septum   was   composed   of   the   same   tissue   of   the   kidney’s   fibrous capsule.   A   coronal   section   of   the   kidney   showed   that   there   was   also   a   variation   regarding   the   calyces:   they   joined   independently   in   order   to   form   the   renal pelvis. Conclusions:   We   believe   that   knowledge   regarding   variations   of   the   kidney   is   of   great   significance   to   the   clinician   and   the   surgeon,   and   many   of   them   can produce discomforting symptoms.
