"Differential Diagnosis"
"Contrast will be present in the extraperitoneal spaces surrounding the bladder, usually streaky as it dissects along fascial planes, and denser than seen in intraperitoneal rupture. The typical location is at bladder base anterolaterally. Extraperitoneal rupture is usually associated with pelvic fractures; the mechanism may be from direct puncture of the bladder wall or shearing forces as the pelvis is fractured 3."
"Complex extraperitoneal rupture describes extension of extraluminal contrast to the thigh, scrotum or perineum 8."
"Intraperitoneal rupture requires surgical repair while extraperitoneal injuries may be treated conservatively with a urinary catheter. In cases of bony fragments within the urinary bladder, rectal or vaginal lacerations, or bladder neck injury, immediate repair is needed to prevent fistula formation. Bladder may also be repaired in cases of internal fixation for pelvic fractures to prevent urine contamination of orthopaedic hardware 9. The presence of other renal tract injuries involving the ureters or urethra may require separate intervention 9."
