Optimizing intravenous urography (IVU) sequences by removing specific films can reduce costs by 18% without impacting diagnostic sensitivity for urinary tract abnormalities.

Area of Science:

  • Radiology
  • Medical Imaging
  • Urology

Background:

  • Standard intravenous urography (IVU) sequences involve multiple radiographic films.
  • Optimizing these sequences is crucial for balancing diagnostic accuracy and healthcare costs.

Purpose of the Study:

  • To identify an IVU film sequence that maximizes diagnostic sensitivity while minimizing filming expenses.
  • To evaluate the impact of omitting individual films or combinations of films from a standard IVU protocol.

Main Methods:

  • Retrospective review of 82 IVU series with confirmed abnormalities.
  • Analysis of sensitivity for each film within an 11-film standard IVU sequence.
  • Assessment of abnormalities detected when specific films were omitted.

Main Results:

  • Omitting any single film decreased sensitivity by 0% to 12%.
  • Omitting the preliminary film led to a 12% failure in detecting abnormalities.
  • A nine-radiograph sequence reduced costs by 18% without sacrificing sensitivity.

Conclusions:

  • A nine-film IVU sequence is effective in reducing costs and processing expenses.
  • Reducing the number of films in an IVU sequence can significantly lower costs without compromising the detection of common urinary tract abnormalities.
