Purpose: The purpose of this study was to establish guidelines for diagnost
ic imaging for bladder rupture in the blunt trauma victim with multiple inj
uries, in whom the delay caused by unnecessary testing can hamper the traum
a surgeon and threaten outcome.
Method: We undertook chart review (1995-1999) of patients with blunt trauma
and bladder rupture at our four institutions and performed focused literat
ure review of retrospective series.
Results. Of our 53 patients, identified, all had gross hematuria and 85% ha
d pelvic fracture. Literature review revealed similar rates.
Conclusion. The classic combination of pelvic fracture and gross hematuria
constitutes an absolute indication for immediate cystography in blunt traum
a victims. Existing data do not support lower urinary tract imaging in all
patients with either pelvic fracture or hematuria alone. Clinical indicator
s of bladder rupture may be used to identify atypical patients at higher ri
sk. Patients with isolated hematuria and no physical signs of lower urinary
tract injury may be spared the morbidity, time, and expense of immediate c
ystographic evaluation.
