    Artificial sphincters show mixed results for urinary incontinence treatment. While 38% of patients improved, significant complications like urethral erosion and infection occurred, necessitating device removal in some cases.

    Area of Science:

    • Urology
    • Medical Device Technology

    Background:

    • Urinary incontinence affects a significant patient population.
    • Various etiologies contribute to urinary incontinence, including post-prostatectomy, myelodysplasia, and post-surgical female incontinence.
    • Artificial sphincters represent a surgical option for managing refractory urinary incontinence.

    Purpose of the Study:

    • To evaluate the efficacy and complications of artificial sphincter implantation for urinary incontinence treatment.
    • To assess patient outcomes following artificial sphincter implantation.

    Main Methods:

    • A cohort of 21 patients (2 female, 19 male) received artificial sphincters between December 1977 and November 1978.
    • Patients presented with diverse causes of incontinence, including post-prostatectomy, myelodysplasia, and failed bladder neck suspension.

  • Outcomes were assessed based on postoperative improvement, persistent incontinence, and device-related complications.

    • Main Results:

    • 38% of patients demonstrated excellent or improved outcomes post-implantation.
    • 24% of patients experienced persistent, unabated urinary incontinence.
    • 24% of patients developed urethral erosion at the cuff site, and 14% required device removal due to infection.

    Conclusions:

    • Artificial sphincter implantation offers a potential treatment for urinary incontinence, with a notable percentage of patients experiencing improvement.
    • However, the procedure is associated with significant complication rates, including urethral erosion and infection, impacting overall success.
    • Careful patient selection and surgical technique are crucial to mitigate risks and optimize outcomes for artificial sphincter use.
