Summary: | The artificial urinary sphincter (AUS) is most known for its use in the treatment of moderate to severe post-prostatectomy stress urinary incontinence. However, another lesser-known indication includes stress incontinence related to intrinsic sphincter deficiency (ISD) in the neurogenic bladder population. The purpose of this review is to discuss specific technical considerations related to device implantation in this population, efficacy, durability, and complications.
We performed a non-systematic literature review using the PubMed Database to identify articles specifically related to treatment of neurogenic urinary incontinence using an artificial urinary sphincter.
More proximal placement of the cuff at the bladder neck is preferred in the neurogenic population due to higher rates of erosion and complications related to frequent clean intermittent catheterization or cystoscopic procedures when placed along the bulbar urethra. Robotic-assisted laparoscopic cuff placement has emerged as a safe and effective alternative to open surgery in select patients. Although continence rates are highly variable due the subjectivity of the term, functional continence (≤1 pad, ± nighttime incontinence) is reported to be between 75-90%. The need for secondary surgery for explanation with or without revision/replacement is higher in neurogenic patients compared to non-neurogenic patients.
Neurogenic urinary incontinence is a complex condition due to the interplay of urethral resistance and bladder function/compliance. While there are a variety of strategies to treat neurogenic incontinence, high quality data from direct comparisons are lacking. Although AUS comes with a high revision rate, functional outcomes for continence with bladder neck placement are promising in this population. |
