Bladder autoaugmentation in adult patients with neurogenic voiding dysfunction

Area of Science:

• Urology
• Surgical Innovation
• Patient Outcomes

Background:

• Bladder autoaugmentation serves as an alternative to enterocystoplasty for non-malignant low-capacity, high-pressure bladders.
• It is particularly effective for neuropathic hyperreflexive bladders resistant to less invasive treatments.
• This procedure allows for future enterocystoplasty or deafferentation if needed.

Purpose of the Study:

• To evaluate the efficacy and outcomes of bladder autoaugmentation in patients with various bladder dysfunctions.
• To assess the impact of bladder autoaugmentation on bladder capacity, compliance, and voiding function.
• To identify factors influencing functional rehabilitation and potential complications.

Main Methods:

• A retrospective analysis of 50 patients undergoing bladder autoaugmentation over seven years.
• Assessment of changes in bladder capacity, compliance, and residual urine.
• Monitoring for functional rehabilitation timelines and adverse events.

Main Results:

• Significant increases in bladder capacity and compliance were observed post-surgery.
• Most patients required intermittent catheterization due to increased residual urine.
• Functional rehabilitation varied, with improvements seen 1-6 months post-surgery, and in some cases, up to a year.
• Low-dose anticholinergics may accelerate therapeutic effects.

Conclusions:

• Bladder autoaugmentation is a favorable treatment for selected patients, offering improved bladder function.
• Patient motivation for delayed functional changes and willingness for intermittent catheterization are crucial for success.
• Potential complications include bladder rupture and treatment failure due to psychogenic factors.
