Radiography: double contrast cystography

Synonym(s): DCC

Contributor(s): Barbara J Watrous

Introduction

  • Introduction of negative and positive contrast into bladder gives maximum radiographic information on bladder disease.

Uses

  • Investigation of hematuria Hematuria.
  • Investigation of dysuria.
  • Identification of non-radiodense uroliths Urolithiasis Bladder: stones - double contrast cystography .
  • Assessment of bladder wall thickness.
  • Assessment of bladder mucosal lining Bladder: cystitis - double contrast cystogram (lateral) .
  • Identification of bladder masses.

Advantages

  • Relatively simple procedure in most patients.
  • Non-invasive.
  • Improved mucosal detail over pneumocystogram or positive contrast cystogram.
  • Enables identification of radiolucent foreign body or blood clots.

Disadvantages

  • Can be impossible to catheterize some patients (with obstructed urethras).
  • Risk of air embolus or bladder rupture if bladder over inflated with air or severe hematuria.
  • Not appropriate if bladder or urethral rupture suspected.
