Urinary undiversion in myelodysplasia: criteria for selection and predictive value of urodynamic evaluation

Area of Science:

• Pediatric Urology
• Neurogenic Bladder Management
• Spinal Cord Anomalies

Background:

• Myelodysplasia often necessitates urinary diversion, such as ileal conduits, in children.
• Ileal conduits can present long-term management challenges.
• Assessing the potential for successful urinary undiversion is crucial for improving quality of life.

Purpose of the Study:

• To describe the evaluation process and selection criteria for urinary undiversion in children with myelodysplasia and ileal conduits.
• To identify factors influencing the success of urinary undiversion.
• To assess the utility of external urethral sphincter electromyography in predicting outcomes.

Main Methods:

• Retrospective review of 15 children with myelodysplasia undergoing urinary undiversion from ileal conduits.
• Evaluation of neurologic and psychologic factors.
• Utilizing external urethral sphincter electromyography for predictive assessment.

Main Results:

• Two-thirds of the selected children achieved a successful outcome after urinary undiversion.
• Neurologic and psychologic factors played a significant role in the selection and outcome.
• External urethral sphincter electromyography was helpful in predicting postoperative continence and managing neurogenic bladder.

Conclusions:

• Urinary undiversion is a viable option for select children with myelodysplasia and ileal conduits.
• Careful patient selection, considering neurologic and psychologic status, is paramount.
• Electromyography of the external urethral sphincter is a valuable tool in managing these complex cases.
