Ileocecal bladder augmentation in myelodysplasia.

Area of Science:

• Pediatric Urology
• Gastrointestinal Surgery
• Reconstructive Urology

Background:

• Myelodysplasia frequently leads to bladder dysfunction requiring surgical intervention.
• Bladder augmentation is a common procedure to improve bladder capacity and compliance.
• The ileocecal segment is one option for bladder augmentation, but its long-term outcomes require evaluation.

Purpose of the Study:

• To evaluate the urodynamic and clinical outcomes of bladder augmentation using the non-detubularized ileocecal segment in children and adolescents with myelodysplasia.
• To identify potential complications and areas for improvement in this surgical technique.

Main Methods:

• A retrospective review of 14 pediatric patients with myelodysplasia who underwent bladder augmentation with an intact ileocecal segment.
• Urodynamic evaluations were performed pre- and post-operatively in 13 patients, with follow-up ranging from 1 to 8 years.
• Analysis of clinical outcomes, including reoperations and complications such as ureteroileal stenosis and urinary tract calculi.

Main Results:

• Postoperative bladder capacity and compliance were normalized in the evaluated patients.
• Cecal contractions occurred in 8 patients despite anticholinergic medication.
• Reflux was observed in 4 patients during cecal contractions, though upper tract issues were not prevalent.
• Three patients required reoperation due to ureteroileal stenosis and/or urinary tract calculi.

Conclusions:

• Non-detubularized ileocecal segment bladder augmentation provides satisfactory clinical results in pediatric myelodysplasia.
• The occurrence of cecal contractions and reflux highlights potential drawbacks of this technique.
• Future strategies involving detubularized bowel segments and intussuscepted valves may mitigate these complications and improve outcomes.
