Infundibulopelvic angle assessment: non-contrast computed tomography vs. traditional methods

Area of Science:

• Radiology and Medical Imaging
• Urology
• Anatomy

Background:

• The infundibulopelvic angle is a critical anatomical measurement.
• Conventional methods for measuring this angle often involve contrast agents, which carry risks and costs.

Purpose of the Study:

• To evaluate the efficacy of non-contrast computed tomography (CT) for quantifying the infundibulopelvic angle.
• To compare measurements from non-contrast CT with traditional contrast-based techniques (intravenous urography or retrograde pyelography).

Main Methods:

• Retrospective analysis of 35 patients undergoing simultaneous kidney multirow CT and contrast-based imaging.
• Measurement of infundibulopelvic angles using both non-contrast CT and conventional methods.
• Paired t-test to compare measurements from the two techniques.

Main Results:

• No statistically significant difference was found between infundibulopelvic angle measurements obtained via non-contrast CT (41.58° ± 16.15°) and traditional methods (42.02° ± 16.96°).
• The p-value was greater than 0.05, indicating comparability.

Conclusions:

• Non-contrast CT provides a reliable and comparable method for measuring the infundibulopelvic angle.
• This novel methodology simplifies the procedure, eliminates the need for contrast agents, reduces costs, and may shorten hospital stays.
