[Urodynamic disorders of upper urinary tracts in neonates and infants: diagnosis and therapeutic policy]

Area of Science:

• Pediatric Urology
• Neonatal Nephrology

Background:

• Infants present with obstructive and functional urodynamic disorders.
• Accurate differentiation is crucial for appropriate management.
• Existing diagnostic methods may require refinement for neonatal populations.

Purpose of the Study:

• To differentiate between obstructive and functional urodynamic disorders in neonates.
• To propose an original examination scheme for this differentiation.
• To evaluate the efficacy of specific interventions.

Main Methods:

• Examination of 52 neonates with obstructive and 46 with functional urodynamic disorders.
• Development and application of an original diagnostic scheme.
• Assessment of transcutaneous puncture nephrostoma and subcutaneous ureterostomas.

Main Results:

• An original scheme for differentiating neonatal urodynamic disorders was proposed.
• Guidelines for one- or two-staged procedures were established.
• The effectiveness of 23 subcutaneous ureterostomas was found to be poor.

Conclusions:

• The proposed examination scheme aids in differentiating neonatal urodynamic disorders.
• Transcutaneous puncture nephrostoma technique is age-specifically outlined.
• Subcutaneous ureterostomies demonstrate limited therapeutic effect in this cohort.
