  • “ Multidetector computed tomography (MDCT) cystography is rapidly becoming the most recommended study for evaluation of the bladder for suspected trauma.”

  • Bladder Trauma: Facts
    Trauma mechanisms
    - Blunt trauma (60-85%)
    - Penetrating trauma (15-40%)
    - Iatrogenic trauma (5%)
  • Bladder Trauma: Facts
    - GU trauma occurs in 5-10% of all patients with trauma
    - Bladder injury occurs in 1.6% of blunt trauma cases
    - Bladder rupture occurs in 2-11% of patients with pelvic trauma
    - However, 60-90% of patients with bladder rupture have a pelvic fracture
  • Bladder Trauma: Facts
    - 70-80% of cases are extraperitoneal rupture
    - 15-20% of cases are intraperitoneal rupture
    - 5-10% of cases are combined bladder rupture
    - intraperitoneal rupture has higher morbidity and mortality
  • Calcifications in the Ureter and Bladder: Differential Dx
    - TB
    - Schistosomiasis
    - Alkaline encrusted pyelitis
    - Radiation injury
  • "Bladder cancer tends to show peak enhancement with the 60-second scanning delay. Multidetector row helical CT is useful in the detection and staging of bladder cancer."

  • "Sensitivity and specificity in the diagnosis of perivesical invasion were 89% and 95% respectively, in 67 patients and increased to 92% and 98% respectively, in 44 patients with a time interval of 7 or more days between TURP and CT."

  • "The cancer detection rate and positive predictive value for cancer detection was 97% and 95% respectively, in 67 patients and increased to 100% and 100% in 44 patients with a time interval of 7 or more days between TURP and CT."
