Management of Gross Hematuria

Immediate Assessment and Management

In a patient with gross hematuria and a suprapubic catheter, immediately assess for bladder trauma, evaluate for infection, ensure adequate catheter drainage, and perform retrograde cystography if trauma is suspected, as recommended by the American Urological Association 1, 2
Gross hematuria combined with pelvic fracture indicates bladder injury in 29% of cases, requiring immediate imaging, according to the American College of Surgeons 3
Perform retrograde cystography in stable patients with gross hematuria if there is any mechanism concerning for bladder injury or pelvic ring fracture, as suggested by the European Association of Urology 1, 4
Look for clinical indicators of bladder rupture, such as inability to void, low urine output, elevated blood urea nitrogen/creatinine, abdominal distention, suprapubic pain, or free intraperitoneal fluid on imaging, as recommended by the American Urological Association 1, 3
Proper cystography requires retrograde gravity filling with minimum 300 mL contrast until maximal bladder distention, as stated by the American College of Radiology 1

Intraperitoneal bladder rupture requires immediate surgical exploration and primary repair, as recommended by the American Urological Association 1, 2
Uncomplicated extraperitoneal bladder injuries can be managed conservatively with urinary drainage via the existing suprapubic catheter for 2-3 weeks, with expectation of healing in >85% of cases within 10 days, according to the European Association of Urology 1, 2, 5
Complex extraperitoneal ruptures require surgical exploration and repair, as suggested by the American College of Surgeons 2, 5

Maintain continuous bladder drainage to prevent clot retention and bladder overdistention, as recommended by the World Health Organization 2, 5
Assess for coagulopathy or anticoagulation therapy, though hematuria should not be attributed solely to anticoagulation without ruling out structural causes, as stated by the American Urological Association 3
Consider cystoscopy and imaging to evaluate for bladder pathology or other structural causes if hematuria persists despite conservative measures, as suggested by the European Association of Urology 3
Maintain adequate hydration to promote good urine flow and prevent clot formation, as recommended by the National Institute of Diabetes and Digestive and Kidney Diseases 6

Persistent gross hematuria despite conservative measures requires urology consultation, as recommended by the American Urological Association 3
Suspicion of bladder injury, especially in the context of pelvic trauma, warrants immediate urology or trauma surgery consultation, as suggested by the American College of Surgeons 3
Penetrating trauma with pelvic trajectories requires radiological, endoscopic, or surgical evaluation of the bladder, as stated by the American Urological Association 1
