Pdf Summary

Sacral neuromodulation (SNM) is a minimally invasive treatment option for patients with urinary and bowel symptoms that have failed conservative treatment options. The Interstim® Therapy system is commonly used for this procedure. The initial test phase can be performed using a percutaneous nerve evaluation (PNE) or a staged permanent quadripolar tined lead procedure. Patients who report a greater than 50% reduction in symptoms during the test period are considered candidates for permanent implantation with SNM.<br /><br />A retrospective chart review was performed to assess the success rate of implantation using a bilateral advanced test procedure in patients with refractory urinary and/or bowel control. Of the 119 patients who underwent the bilateral advanced test procedure, 98.3% successfully proceeded to permanent implantation. The rate of adverse events, including lead removal and revisions, was 24.4%.<br /><br />Previous studies have reported success rates of up to 77% with unilateral lead placement. However, this study found a higher success rate with bilateral lead placement during the test period. The rate of adverse events was similar to that of previous studies.<br /><br />Careful patient selection was attributed to the high rate of successful implantation. The authors conclude that bilateral advanced test sacral neuromodulation is an effective treatment option for patients with refractory urinary and bowel symptoms.<br /><br />This study provides evidence for the efficacy of bilateral advanced test sacral neuromodulation as a treatment option for patients with refractory urinary and bowel symptoms. However, further research is needed to compare the outcomes of bilateral and unilateral lead placement.
