Sacral neuromodulation as an effective treatment for refractory pelvic floor dysfunction

Area of Science:

• Urology
• Neurology
• Pelvic Health

Background:

• Pelvic floor dysfunction presents complex challenges, often refractory to conventional treatments.
• Current therapies may yield suboptimal results or significant side effects.
• Sacral nerve stimulation (SNS) emerges as a potential alternative for refractory cases.

Purpose of the Study:

• To evaluate the long-term efficacy of sacral nerve stimulation for pelvic floor dysfunction.
• To assess the complication rates associated with sacral nerve stimulation.
• To determine the effectiveness of test stimulation in patient selection.

Main Methods:

• Sixty-four patients with voiding dysfunction and/or pelvic pain underwent permanent sacral nerve implant after successful percutaneous nerve evaluation.
• Patients were assessed for voiding symptoms (frequency, urgency, incontinence, retention) and pelvic pain using subjective and objective measures.
• Follow-up evaluations occurred at 1, 3, 6, 12, 24 months, and annually thereafter.

Main Results:

• 80% of patients experienced ≥50% improvement in symptoms and quality of life.
• Significant reductions in urinary frequency, incontinence episodes, and pad usage were observed.
• Patients with urinary retention showed improved voiding, and those with chronic pelvic pain reported decreased pain severity (5.8 to 3.7).
• Complications occurred in 18.7% of patients, deemed minimal.

Conclusions:

• Sacral nerve stimulation is a safe and effective long-term therapy for various forms of pelvic floor dysfunction.
• The procedure demonstrates durable efficacy across diverse patient complaints.
• Percutaneous nerve evaluation serves as a reliable predictor of successful long-term outcomes.
