Bladder neck cinch for pediatric neurogenic outlet deficiency

Area of Science:

• Pediatric Urology
• Surgical Techniques
• Neurogenic Bladder Management

Background:

• Urinary incontinence in children with neurogenic outlet deficiency is often managed with fascial bladder neck slings.
• Existing slings typically apply only partial pressure around the bladder neck, limiting their effectiveness.

Purpose of the Study:

• To evaluate the efficacy of a rectus fascia bladder neck cinch procedure.
• This technique aims to increase outlet resistance by applying circumferential pressure and elevation around the bladder neck.

Main Methods:

• Fifteen children with spina bifida and neurogenic intrinsic sphincter deficiency underwent a rectus fascia bladder neck cinch during augmentation cystoplasty.
• A 1-1.5 cm width of rectus fascia was harvested, cinched around the bladder neck, and secured.

Main Results:

• The study included 14 girls and 1 boy aged 4-17 years with poorly compliant or small capacity bladders.
• At 10-36 months follow-up, 60% (9 out of 15) of the children achieved dryness, defined as no leaks or pads for 4 hours post-catheterization and overnight continence.
• All patients continued clean intermittent catheterization post-operatively.

Conclusions:

• The rectus fascia bladder neck cinch is an effective surgical option for managing urinary incontinence in children with neurogenic bladder outlet deficiency.
• However, the procedure's effectiveness was comparable to existing bladder neck slings, not superior.
• The authors noted a subsequent modification of their technique due to results not fully meeting expectations.
