[Simple method of residual urine determination without bladder catheterization (author's transl)]

Area of Science:

• Urology
• Medical Diagnostics
• Clinical Chemistry

Context:

• Accurate measurement of residual urine is crucial for diagnosing and managing bladder dysfunction.
• Traditional methods like bladder catheterization can be invasive and uncomfortable for patients.
• The need for a non-invasive or minimally invasive, yet accurate, method for residual urine determination persists.

Purpose:

• To introduce a simple photometric method for determining residual urine volume.
• To validate the accuracy of this photometric method against standard bladder catheterization.
• To explore the utility of urine obtained via suprapubic puncture for antibiotic sensitivity testing.

Summary:

• A straightforward photometric technique employing a nomogram was developed to quantify residual urine.
• The method involves suprapubic puncture, allowing for urine collection on an outpatient basis if needed.
• Results demonstrated a strong correlation between the photometric method and traditional bladder catheterization outcomes.

Impact:

• Provides a less invasive and potentially more accessible method for assessing residual urine.
• Facilitates outpatient urine collection for diagnostic purposes, including antibiotic sensitivity testing.
• Offers a validated, simple, and accurate alternative to bladder catheterization in clinical practice.
