Management of Bladder Perforation with Hematuria

Diagnostic Evaluation

The American Urological Association recommends performing retrograde cystography immediately in any patient with gross hematuria and suspected bladder injury, with a minimum of 300 mL of contrast via retrograde gravity filling to achieve maximal bladder distention 1, 2, 3, 4
CT cystography has 85-100% accuracy for diagnosing bladder perforation and allows simultaneous evaluation of other injuries, with intraperitoneal injuries showing contrast outlining bowel loops and filling intraabdominal spaces, and extraperitoneal injuries showing contrast confined to the pelvis 6

The American College of Surgeons recommends immediate surgical repair for all intraperitoneal bladder perforations, as a Standard recommendation (Grade B evidence), due to the risk of peritonitis and sepsis 1, 2, 7
Uncomplicated extraperitoneal bladder injuries should be managed with catheter drainage for 2-3 weeks, as over 85% heal within 10 days with catheter drainage alone 2, 7
Surgical repair is required for complicated extraperitoneal injuries, including large extraperitoneal bladder injuries, bladder neck involvement, concurrent rectal or vaginal injury, adjacent orthopedic implants, and penetrating injuries with pelvic trajectories 1, 6, 7, 8

For hemodynamically unstable patients, delay surgical repair until stabilization is achieved, and consider bilateral nephrostomy combined with urinary catheterization as a temporizing measure 1, 6
The World Journal of Emergency Surgery recommends maintaining continuous bladder drainage to prevent clot retention and overdistention, and following up with cystography to confirm healing in complex repairs 2, 6, 8

Do not attribute hematuria solely to anticoagulation without ruling out structural bladder injury, as 29% of patients with pelvic fracture and gross hematuria have bladder rupture requiring immediate diagnosis 1, 3, 5, 8
Do not delay imaging in patients with pelvic fracture and gross hematuria, and do not perform inadequate cystography by clamping Foley and relying on IV contrast accumulation 1, 2, 5
