A simplified system for collecting 24-hour urine samples.

Area of Science:

• Urology
• Clinical Chemistry
• Biomedical Engineering

Background:

• Accurate 24-hour urine volume measurement is crucial for diagnosing various renal and metabolic conditions.
• Traditional 24-hour urine collection methods using large bottles can be cumbersome and prone to patient non-compliance.
• Existing methods may present challenges in sample stability and accurate volume determination.

Purpose of the Study:

• To describe a novel system for collecting small aliquots of each voiding.
• To enable accurate calculation of 24-hour urine volume and facilitate chemical analysis.
• To present a reusable and cost-effective alternative for urine sample collection.

Main Methods:

• A system designed to collect small, sequential urine aliquots from each voiding.
• Pooling of collected aliquots for laboratory analysis.
• Utilizing reusable components within the collection system.

Main Results:

• The described system facilitates the collection of multiple small urine samples throughout a 24-hour period.
• Pooled samples allow for accurate determination of total 24-hour urine volume.
• The system enables subsequent chemical analysis of the pooled urine sample.
• Reusable components contribute to a reduced cost per collection compared to conventional methods.

Conclusions:

• The novel aliquot collection system provides an efficient and accurate method for 24-hour urine volume assessment.
• This approach offers a practical and potentially more cost-effective solution for clinical urine sample collection.
• The system supports both quantitative volume measurement and qualitative chemical analysis of urine.
