ABSTRACT
Background:
The
kidneys
are
retroperitoneal
organs
with
a
unique
embryological
formation.
They
are
formed
by
two
distinct
embryological
bases,
one
for
the
collecting
system
and
one
for
the
parenchymatous
tissue.
The
kidneys
are
often
target
to
anatomical
variations
regarding
its
vessels,
its
collecting
system,
its
position
on
the
abdominal
cavity
and
others.
Most
of
those
variations
happen
due
to
different
stimuli
during
its
embryonic
development.
Such
is
the
case
of
the
distinct
fetal
period
lobulation,
which
happens
uncommonly.
Many
of
these
abnormalities
may
produce
clinical
symptoms,
moreover,
variations
can
cause
confusion
among
clinicians
regarding
diagnostic
aspects
or
surgeons
during
partial
nephrectomy,
kidney
transplants
and
other
surgical
procedures involving the retroperitoneal area or the kidney itself.
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.
