• RF
• Lateral survey film
• The urinary bladder is not visible and there is
  decrease in abdominal detail in the caudal
  abdominal cavity.
• The retroperitoneal detail is normal.
• A small, triangular mineral opacity structures is
  present at the ventral body wall.
• Fracture of the ilial body is apparent.
• Lateral film of IV pyelogram
• There is no evidence of leakage of contrast
  material into the retroperitoneal space.
• The termination of the ureters at the bladder is
  not defined by the study.
• Contrast is present free within the abdominal
  cavity.

• RD
• Rupture of the urinary tract
• Ilial body fracture
• Small bone fragment at the ventral aspect of the
  abdominal wall
• R/O
• Rupture of the bladder or at the junction of the
  ureters with the bladder.
• Small bone fragment suggests partial avulsion of
  the prepubic tendon at its attachment to the
  pubis.
• Next
• Exploratory laparotomy

• RF
• Urinary bladder is moderately distended.
• There is calcific rimmed oval structure just
  caudal to the liver margin on the lateral view .
  This corresponds to an incidental finding of fat
  mineralization.
• 8 Lumbar vertebrae are noted.
• RD
• Moderately distended urinary bladder
• Next
• Abdominal ultrasound

• The liver extends beyond the costal arches but
  the borders are sharp and clear.
• The stomach wall appears mildly thick.
• There are multiple mineral opacity structures
  noted in the urinary bladder consistent with
  calculi.
• There is an incidental finding of bilateral
  coxofemoral degenerative joint disease.
• RD
• Cystic calculi
• Next
• Abdominal ultrasound

• RF
• Two discrete, roughly marginated opaque
  structures are present overlying the urinary
  bladder in both views.
• The craniolateral margin of the left kidney is
  slightly flattened.
• Mild arthritis of the right hip.
• RD
• Two cystic calculi
• Next
• Ultrasound

21
M DSHScooter

• Hx Two films are provided. The first was taken
  in 1999 prior to a perineal urethrostomy. The
  second was taken in 2001 because the patient
  presented with signs of urinary tract obstruction.

• RF
• 1999
• The urinary bladder contains a single 2mm round
  mineral opacity structure.
• There is a granular appearance to the ventral
  aspect of the bladder suggesting that mineralized
  sediment is present.
• Irregular mineral opacity material is present in
  the pelvic and proximal penile urethra.
• There is an incidental finding of mild
  spondylosis at the lumbosacral junction.
• 2001
• There are multiple variably-sized mineral opacity
  structures within the bladder and extending into
  the bladder neck.
• The bladder neck appears elongated.
• A gas bubble is also present within the bladder
  lumen.
• RD
• 1999
• Cystic calculi with evidence of mineralized
  bladder sediment
• Mineralized sediment/small calculi within the
  urethra
• 2001
