title: Dynamic cystography can replace cystoscopy following prostate seed implantation.
abstract: OBJECTIVE
  To determine if dynamic cystography can replace cystoscopy following prostate seed implantation.
  
  
  METHODS
  Three hundred three consecutive patients underwent prostate seed implantation using the real-time method. Following implantation, 60 cc of contrast media was injected into the bladder using continuous fluoroscopy. If any seed motion was detected, cystoscopy was performed and any seeds encountered were removed. Patients were followed after discharge for any seeds passed in the urine.
  
  
  RESULTS
  Of the 303 patients, 3 (1%) were found to have one or more seeds in the bladder. No patients passed seeds following discharge. There were no adverse events associated with the cystography.
  
  
  CONCLUSIONS
  Dynamic cystography can replace cystoscopy as the postimplant study to evaluated misplaced intravesical or urethral seeds.
