GAUZE SPONGE PSEUDOTUMOR IN A DOG

• This patient is a 135 pound Saint Bernard and it
  recovered normally from surgery.  The urinary
  tract will be evaluated routinely for the rest of
  it's life and a high quality, meat-based diet
  will be fed.  The probability of a normal and
  long life is good.

2
A firm, three inch diameter mass was palpable in
the dorsal lower abdomen.  The forceps points to
the area of the lower abdomen under which lies
the mass. 
3
A nondescript mass adhering to the right wall of
the bladder and incorporating the omentum,
suspensory ligament of the bladder and encircling
the right distal ureter was discovered.
4
Surgical removal of the mass required separating
it from the bladder wall and subsequent repair of
the bladder wall.  As well, the ureter was
removed from its entry into the bladder and the
distended, turgid right kidney was removed.

This view of the incised kidney shows the
extensive destruction of the internal kidney
tissue.
