Urethral pressure profile measurements in children

Area of Science:

• Urology
• Physiology

Background:

• Neurogenic micturition dysfunction can increase infravesical flow resistance.
• Understanding bladder-urethra junction physiology is crucial for diagnosing urinary issues.

Purpose of the Study:

• To describe pathological changes in neurogenic micturition dysfunctions.
• To present urethral pressure profile (UPP) registration as a method for diagnosing infravesical flow resistance.
• To evaluate the UPP method in children with subvesical urinary dysfunctions.

Main Methods:

• Physiological processes of micturition were reviewed.
• Pathological changes leading to increased infravesical flow resistance were considered.
• Urethral pressure profile (UPP) was registered using a catheter with a lateral eye and constant slow perfusion.
• Preliminary trials were conducted to determine measurement errors.

Main Results:

• The UPP method was established as suitable for determining dysfunctions.
• Measurement errors were identified and quantified through preliminary trials.
• Examples demonstrated the application and findings of UPP in children with various subvesical urinary dysfunctions.

Conclusions:

• Urethral pressure profile registration is an effective method for diagnosing neurogenic micturition dysfunctions and infravesical flow resistance.
• The UPP method provides valuable insights into pediatric urological conditions.
• Careful consideration of measurement errors is essential for accurate UPP interpretation.
