Bladder injuries from trauma often present with pain and hematuria. Prompt diagnosis using retrograde cystography is crucial for effective treatment of bladder ruptures.

Area of Science:

  • Urology
  • Trauma Surgery
  • Diagnostic Imaging

Background:

  • Bladder injuries commonly result from external trauma, presenting with lower abdominal pain, tenderness, and hematuria.
  • Simultaneous bladder and posterior urethral rupture can occur, often missed preoperatively.
  • Delayed diagnosis may arise from patient reluctance to seek care or physician misdiagnosis, particularly in vulnerable populations.

Purpose of the Study:

  • To highlight the clinical presentation of bladder injuries.
  • To emphasize the diagnostic utility of retrograde cystography.
  • To discuss challenges in diagnosing simultaneous bladder and urethral ruptures.

Main Methods:

  • Review of clinical presentations of bladder trauma.
  • Description of retrograde cystography technique for diagnosing bladder ruptures.

  • Analysis of factors contributing to delayed or missed diagnoses.
  • Main Results:

    • Bladder rupture incidence is 6-10% in pelvic fractures.
    • Retrograde cystography with 400 ml contrast dye is effective for diagnosing intraperitoneal and extraperitoneal ruptures.
    • False-negative cystograms can occur with insufficient contrast volume (≤250 ml) in penetrating injuries.

    Conclusions:

    • Early recognition of bladder injury symptoms is vital.
    • Retrograde cystography is the gold standard for diagnosing bladder ruptures.
    • Adherence to proper contrast volume in cystography prevents false-negative results.
