Traumatic injury to the urinary bladder can be graded using the Bladder Injury Scale.
Type of Injury
Extent
Grade
hematoma or contusion
intramural
I
laceration
partial thickness
extraperitoneal, < 2 cm
II
extraperitoneal, >= 2 cm
III
intraperitoneal, < 2 cm
intraperitoneal, >= 2 cm
IV
extension into the bladder neck
V
extension into the ureteral orifice at the trigone
If more than 1 injury is present, then advance grade by 1 up to Grade III.
where:
• I assume the advance in grade for multiple injuries applies for Grade II to III but not III to IV (see Testis Injury Scale).
