Detrusorectomy for neuropathic bladder in patients with spinal dysraphism

Area of Science:

• Urology
• Pediatric Surgery
• Regenerative Medicine

Background:

• Spina bifida often leads to neurogenic bladder dysfunction, characterized by poor bladder volume and compliance.
• Urinary incontinence in these patients significantly impacts quality of life and can lead to renal complications.

Purpose of the Study:

• To evaluate the outcomes of detrusorectomy in patients with spina bifida experiencing incontinence due to inadequate bladder capacity or compliance.
• To assess the efficacy of detrusorectomy as a standalone procedure or in combination with other surgical interventions.

Main Methods:

• Detrusorectomy was performed on 35 patients with spina bifida requiring bladder augmentation.
• Procedures were combined with continent catheterizable vesicostomy, ureteral reimplantation, and/or sling/Burch cystourethropexy in select cases.
• Outcomes were assessed based on changes in bladder volume, compliance, and patient continence status.

Main Results:

• Detrusorectomy improved bladder compliance in 46% and bladder volume in 37% of the 35 treated patients.
• Continence was achieved in 19 of 25 patients who underwent combined sling/Burch cystourethropexy.
• Four patients experienced poor results, with 3 requiring secondary ileocystoplasty due to decreased volume and compliance.

Conclusions:

• Detrusorectomy is a safe and potentially beneficial procedure for enhancing bladder volume and compliance in neurogenic bladder dysfunction.
• It may obviate the need for ileocystoplasty in a subset of patients with spina bifida.
• The procedure can be effectively combined with other reconstructive urological surgeries.
