Intravenous vs. oral hydration administration for optimal ureteral opacification in computer tomographic urography

Area of Science:

• Radiology
• Medical Imaging
• Urology

Background:

• Computed tomographic urography (CTU) is the standard for detecting urinary tract diseases.
• Optimizing urinary tract visualization in CTU is crucial for accurate diagnosis.
• Current CTU protocols lack standardized methods for optimal urinary tract opacification.

Purpose of the Study:

• To compare the effectiveness of oral hydration versus intravenous hydration for urinary tract opacification in CTU.
• To evaluate ureteral distention and opacification in patients undergoing CTU with different hydration methods.
• To determine if oral hydration can achieve diagnostic quality comparable to intravenous hydration.

Main Methods:

• Retrospective chart review of 176 patients undergoing CTU in 2013.
• Comparison between an academic institution (IV hydration) and an outpatient center (oral hydration).
• Two experienced radiologists assessed ureteral distention and urinary tract opacification, blinded to hydration method.

Main Results:

• Analysis of 344 ureters showed no statistically significant difference in mean opacification scores between oral and IV hydration methods.
• Mean maximal ureteral widths were largest in the mid and proximal ureter.
• No significant difference in diagnostic quality was observed between the hydration groups.

Conclusions:

• Oral hydration is a viable and effective alternative to IV hydration for CTU.
• Oral hydration protocols are easier to implement, more cost-effective, and require fewer hospital resources.
• Oral hydration can achieve diagnostic quality comparable to IV hydration, supporting its use in cost-containment strategies.
