  Sacral Nerve Stimulation for the Treatment of Urge Urinary Incontinence

Description:
Sacral nerve stimulation, also known as sacral nerve neuromodulation (SNM), involves the implantation of a permanent device that modulates the neural pathways controlling bladder function.
 
Treatment using sacral nerve neuromodulation, also known as indirect sacral nerve stimulation, is one of several alternative modalities for individuals with urinary incontinence (urge incontinence, significant symptoms of urgency-frequency, nonobstructive urinary retention) who have failed behavioral (e.g., prompted voiding) and/or pharmacologic therapies. Urge incontinence is defined as leakage of urine when there is a strong urge to void. Urgency-frequency is an uncontrollable urge to urinate, resulting in very frequent, small volumes. Urgency-frequency is a prominent symptom of interstitial cystitis. Urinary retention is the inability to completely empty the bladder of urine.
 
The SNM device consists of an implantable pulse generator that delivers controlled electrical impulses. This pulse generator is attached to wire leads that connect to the sacral nerves, most commonly the S3 nerve root. Two external components of the system help control the electrical stimulation. A control magnet is kept by the individual and can be used to turn the device on or off. A console programmer is kept by the physician and used to adjust the settings of the pulse generator.
 
Prior to implantation of the permanent device, patients undergo a peripheral nerve stimulation test to estimate potential response to SNM. This procedure is done under local anesthesia, using a test needle to identify the appropriate sacral nerve(s). Once identified, a temporary wire lead is inserted through the test needle and left in place for several days. This lead is connected to an external stimulator, which is carried by individuals in their pocket or on their belt. The results of this test phase are used to determine whether patients are appropriate candidates for the permanent device. If individuals show a 50% or greater reduction in incontinence frequency, they are deemed eligible for the permanent device.
 
The second type of testing is a 2-stage surgical procedure. In the first stage, a quadripolar-tined lead is implanted (stage 1). The testing phase can last as long as several weeks, and if patients show a 50% or greater reduction in symptom frequency, they can proceed to stage 2 of the surgery, which is permanent implantation of the neuromodulation device. The 2-stage surgical procedure has been used in various ways. They include its use instead of percutaneous nerve evaluation, for individuals who failed percutaneous nerve evaluation, for individuals with an inconclusive percutaneous nerve evaluation, or for individuals who had a successful percutaneous nerve evaluation to refine individual selection further.
 
The permanent device is implanted with the individual under general anesthesia. The electrical leads are placed in contact with the sacral nerve root(s) via an incision in the lower back, and the wire leads are extended through a second incision underneath the skin across the flank to the lower abdomen. Finally, a third incision is made in the lower abdomen where the pulse generator is inserted and connected to the wire leads. Following implantation, the physician programs the pulse generator to the optimal settings for that patient. The patient can switch the pulse generator between on and off by placing the control magnet over the area of the pulse generator for 1–2 seconds.
 
Regulatory Status
In 1997, the Medtronic Interstim Sacral Nerve Stimulation system received U.S. Food and Drug Administration (FDA) approval for marketing for the indication of urinary urge incontinence in patients who have failed or could not tolerate more conservative treatments. In 1999, the device received FDA approval for the additional indications of urgency-frequency and urinary retention in patients without mechanical obstruction. In 2006, the InterStim II® System (Medtronic) was approved by the FDA through the premarket approval process for the treatment of intractable cases of overactive bladder and urinary retention. The new device is smaller and lighter than the original and is reported to be suited for those with lower energy requirements or small stature. The device also includes updated software and programming options.
 
In 2019, the Axonics® Sacral Neuromodulation System (Axonics) received premarket approval from the FDA for treatment of urinary retention and symptoms of overactive bladder. This system has a rechargeable battery that has a device life of 15 years after implantation.
 
In 2023, the Virtis™ Sacral Neuromodulation System (Nuvectra) was approved by the FDA for treatment of urinary retention and symptoms of overactive bladder, including urinary urge incontinence and significant symptoms of urgency-frequency in patients who have failed more conservative treatments.

Rationale:
Literature published since these 2000 was searched in October 2002 to update this policy.
 
Urge Incontinence.
A multicenter, randomized controlled clinical trial, conducted as part of the U.S. Food and Drug Administration (FDA) approval process, concluded that SNM reduced urge incontinence compared to control patients. This well-designed trial, using standardized clinical and functional status outcomes measurements, enrolled patients with severe urge incontinence who had failed extensive prior treatments. The magnitude of effect (approximately one half of the patients become dry, three quarters experience at least 50% reduction in incontinence) was fairly large, probably at least as great as with surgical procedures, and larger than expected from a placebo effect or from conservative measures such as behavioral therapy or drugs. However, due to the protocol that selects patients who are likely to benefit based on the peripheral nerve evaluation test, this magnitude of effect is overestimated relative to the total pool of patients with refractory urge incontinence. On the other hand, this screening step avoids an invasive procedure and implantation of the SNS device in patients who are less likely to benefit, thus reducing morbidity and unnecessary treatment.
 
The therapy evaluation test, in which the device is turned off and patients thus serve as their own controls, provided further evidence that the effect on incontinence is due to electrical stimulation, and demonstrates that the effect of SNS is reversible. The cohort analysis of the clinical trial provides some evidence that the effect of SNS is maintained for up to 2 years. There was a high rate of adverse events reported in this clinical trial. Most of the adverse events were minor and reversible; however, approximately one third of patients required surgical revision for pain at the operative sites or migration of the leads. It is not known to what extent these adverse events and the need for surgical revisions may improve as more experience with the device accumulates.
 
There were inadequate data on other indications for SNS, including treatment of urge incontinence due to neurologic conditions, stress incontinence, or other chronic voiding dysfunctions. An update of the literature since the 1998 Assessment again found insufficient data on these indications. No controlled studies were found for urge incontinence due to neurologic conditions, stress incontinence, or other chronic voiding dysfunctions.
 
An additional prospective randomized controlled trial of 44 patients with urge incontinence became available after the 1998 Assessment.  At 6 months, the implant group showed significantly greater improvement on standardized clinical outcomes, as compared to those receiving conservative therapy. The magnitude of effect was substantial. This study provides further evidence of the beneficial effect of SNS for urinary urge incontinence.
 
Urinary Urgency/Frequency
Data on Sacral nerve neuromodulation for the treatment of urinary urgency and frequency was reviewed.  The data considered in this policy review consisted of 1 published randomized controlled trial, a long-term, single-arm cohort study, and additional data submitted to the FDA as part of the approval process. In the multicenter randomized clinical study of 581 patients with a variety of urinary dysfunctions, 220 had significant urgency-frequency symptoms. After 6 months, 83% of patients with urgency-frequency symptoms reported increased voiding volumes with the same or reduced degree of frequency. At 12 months, 81% of patients had reached normal voiding frequency. Compared to a control group, patients with implants reported significant improvements in quality of life, as evaluated by the SF-36 health survey. There has also been interest in the use of sacral nerve stimulation as a treatment of interstitial cystitis, a condition characterized by painful urinary urgency and frequency. A literature search identified 3 cases series of 15, 20, and 25 patients with interstitial cystitis. These studies reported a decrease in both urgency/frequency and pain. There is no separate policy statement for patients with interstitial cystitis, as they would be considered candidates for sacral neuromodulation therapy based on the presence of urgency and frequency alone.
 
Urinary Retention
In the randomized clinical study submitted to the FDA as part of the approval process, 177 of 581 patients had urinary retention.  Patients with urinary retention reported significant improvements in terms of volume catheterized per catheterization, a decrease in the number of catheterizations per day, and increased total voided volume per day. At 12 months post-implant, 61% of patients had eliminated the use of catheterization. Patients with implants also reported improved quality of life.
 
Fecal Incontinence
A literature search identified 4 cases series of 15, 16, 20, and 23 patients, respectively, with fecal incontinence who were treated with sacral neuromodulation as an alternative to anal sphincter surgery.  All series included patients with a variety of etiologies of fecal incontinence, including obstetric injury, spinal cord injury, prior surgery, or idiopathic incontinence.  While sacral neuromodulation for urinary disorders focuses on patients with urinary tracts that appear to be structurally intact but functionally impaired, in contrast, the majority of patients with fecal incontinence have structural impairment of the anal sphincter. Similar to patients with urinary incontinence, placement of the permanent device was preceded by implantation of a temporary electrode to assess treatment effect. However, 3 of the case series on fecal incontinence focus only on those receiving the permanent implant, so it is unknown how many patients were initially evaluated. One case series reported that 20 of 23 patients responded to the temporary electrode and progressed to permanent implantation.  In general, the case series reported improvements in episodes of incontinence and improvements in quality of life in those undergoing permanent implantation. There were also improvements in objective measures, such as anal sphincter resting pressure. The longest follow-up was 24 months. These small case series provide inadequate data to permit scientific conclusions. The trials of patients with urinary incontinence have typically included an arm in which symptoms were evaluated with the device turned off in a blinded manner to evaluate a placebo effect. No such component was included in these case series of fecal incontinence.
 
Constipation
Two small case series were identified that focused on patients with slow transit constipation.  While both reported promising results, these case series of 4 and 8 patients, respectively, are inadequate to permit scientific conclusions.
 
Chronic Pelvic Pain
Siegel and colleagues reported on a case series of 10 patients with chronic pelvic pain.  Their research interest was prompted by the concomitant decrease in pain reported by patients receiving sacral neuromodulation for urinary disorders. The authors did not detail the etiology of the pain syndromes in their case series, but reported that 9 of the 10 patients had a decrease in pain. These data are inadequate to permit scientific conclusions.
2012 Update
A literature search was conducted using the MEDLINE database. There was no new information that would prompt a change in the coverage statement.
 
A 2011 series by Groen and colleagues in The Netherlands was identified (Groen, 2011). A total of 60 patients had at least 5 years of follow-up after SNM for refractory idiopathic urge urinary incontinence. Success was defined as at least a 50% decrease in the number of incontinent episodes or pads used per day. The success rate was 52 of 60 (87%) at 1 month and gradually decreased to 37 (62%) at 5 years. The number of women who were completely continent was 15 (25%) at 1 month and 9 (15%) at 5 years. At the 5-year follow-up, SNM was still used by 48/60 (80%) women. A total of 57 adverse events were reported in 32 of 60 (53%) patients. The most frequent adverse events were hardware-related or pain or discomfort. There were a total of 23 reoperations in 15 patients. In most cases, pain problems were managed conservatively.
 
2013 Update
A literature search was conducted using the MEDLINE database through May 2013. There was no new information identified that would prompt a change in the coverage statement.
   
2014 Update
A literature search conducted through May 2014 did not reveal any new information that would prompt a change in the coverage statement. The key identified literature is summarized below.
 
Ongoing and Unpublished Clinical Trials
InSite for Over Active Bladder (InSite - OAB) (NCT00547378)( MedtronicNeuro, 2014): This randomized open-label trial is comparing the safety and efficacy of sacral neuromodulation using the InterStim device to standard medical therapy in patients with overactive bladder who failed at least 1 previous medication. Patients will be followed for 5 years. The primary efficacy outcomes, change in overactive bladder symptoms at 6 months, were published in 2014 (Seigel, 2014). The primary safety outcome, safety of the tined lead, will be reported at 5 years. The estimated study completion date is November 2016.
 
Refractory Overactive Bladder: Sacral NEuromodulation v. BoTulinum Toxin Assessment (ROSETTA) (NCT01502956): This randomized, open-label trial is comparing the safety and efficacy of sacral neuromodulation (InterStim) with injections of botulinum toxin A for the treatment of refractory urge urinary incontinence. Patients will be followed for 24 months; primary outcomes are changes in urge incontinence symptoms at 6 months. The estimated study completion date is December 2016.
 
Chronic Pelvic Pain
A 2013 systematic review of studies on nerve stimulation for chronic pelvic pain did not identify any RCTs on SNS for treatment of chronic pelvic pain or bladder pain (Tirlapur, 2013). The published evidence is limited to case series. For example, in 2012 Martelluci et al reported on 27 patients with chronic pelvic pain (at least 6 months) who underwent testing for SNM implantation. After a 4-week temporary stimulation phase, 16 of 27 patients (59%) underwent implantation of an InterStim device. In the 16 implanted patients, mean pain on a visual analogue scale was 8.1 before implantation and 2.1 at the 6- and 12-month follow-ups. An earlier study by Siegel et al reported on 10 patients and stated that 9 of the 10 experienced a decrease in pain with SNS stimulation (Seigel, 2001).
 
American College of Obstetricians and Gynecologists (ACOG):
  • A 2005 position statement considered SNS to be beneficial for treating chronic voiding dysfunction (ACOG, 2005).
  • A 2004 position statement recommended that SNS be considered as a treatment option for chronic pelvic pain. According to the ACOG website, accessed in March 2014, the practice bulletin on chronic pelvic pain is no longer maintained (ACOG, 2014).
 
2016 Update
A literature search conducted through May 2016 did not reveal any new information that would prompt a change in the coverage statement. The key identified literature is summarized below.
 
Noblett and colleagues published a twelve-month follow-up of the Insite trial (Noblett, 2014). The analysis included patients included in the SNS group of initial RCT plus additional patients enrolled and implanted in the interim. A total of 340 patients underwent test stimulation, 272 underwent implantation, and 255 completed 12 months of follow-up. In a modified completers’ analysis, the therapeutic success rate was 82%. This modified completers’ analysis included patients who were implanted and had either a baseline or 12-month evaluation, or withdrew from the trial due to a device-related adverse event or lack of efficacy. In an analysis limited to study completers, the therapeutic response rate was 85%. The Noblett analysis did not include data from the control group of patients receiving only standard medical therapy.
 
American Urological Association
In 2014, the American Urological Association issued an updated guideline on diagnosis and treatment of overactive bladder (AUA, 2015). The guideline states that sacral neuromodulation may be offered as a third-line treatment in carefully selected patients with severe refractory symptoms or in those who are not candidates for second-line therapy (eg, oral anti-muscarinics, oral 􀁅3-adrenoceptor agonists or transdermal oxybutynin) and are willing to undergo surgery
 
2017 Update
A literature search conducted through May 2017 did not reveal any new information that would prompt a change in the coverage statement. The key identified literature is summarized below.
 
URINARY INCONTINENCE
Amundsen and colleagues reported on a RCT comparing intra-detrusor injection of onabotulinumtoxinA (n=192) with SNM (n=189) in women with refractory urgency urinary incontinence, defined least 1 supervised behavioral or physical therapy intervention and the use of a minimum of 2 anticholinergics (or inability to tolerate or contraindications to the medication) (Amundsen, 2016). In intention-to-treat analysis, patients in onabotulinumtoxinA-treated patients had greater reductions in urge incontinence per day in SNM-treated patients: 3.9 vs 3.3/ day (mean difference: 0.63; 95% CI 0.13 to 1.14, P=0.01). OnabotulinumtoxinA -treated patients had greater reductions in some overactive bladder-related quality of life questionnaire related measures, although the clinical meaningfulness of the changes was uncertain. Patients in the onabotulinumtoxinA-treated group were more likely to have urinary tract infections (UTIs, 35% vs 11%; risk difference -23%, 95% CI -33% to -13%, P<0.001).
 
2018 Update
A literature search conducted using the MEDLINE database through May 2018 did not reveal any new information that would prompt a change in the coverage statement.
 
2019 Update
A literature search was conducted through May 2019.  There was no new information identified that would prompt a change in the coverage statement.  
 
2020 Update
A literature search was conducted through May 2020.  There was no new information identified that would prompt a change in the coverage statement.  
 
2021 Update
Annual policy review completed with a literature search using the MEDLINE database through May 2021. No new literature was identified that would prompt a change in the coverage statement. The key identified literature is summarized below.
 
A 2018 guideline on urinary incontinence from the Association makes the following statements (EUA, 2018):
 
"Sacral nerve neuromodulation is more effective than continuation of failed conservative treatment for cure of urge urinary incontinence [UUI], but no sham controls have been used."
"Sacral nerve neuromodulation is not more effective than OnabotulinumA toxin 200 U injection at 6 months."
"In those patients who have been implanted, at long-term, 50% improvement of UUI is maintained in at least 50% of patients and 15% may remain cured."
"The use of tined, permanent electrodes in a staged approach results in more patients receiving the final implant than occurs with temporary test stimulation."
 
The guideline also gives a strong recommendation for offering sacral nerve modulation to "patients who have UUI refractory to antimuscarinic therapy."
 
Of note, the 2018 guideline was reprinted in 2020 and will be updated in full for 2021 under the European Association of Urology Guidelines on Non-neurogenic Female Lower Urinary Tract Symptoms.
 
2022 Update
Annual policy review completed with a literature search using the MEDLINE database through May 2022. No new literature was identified that would prompt a change in the coverage statement.
 
2023 Update
Annual policy review completed with a literature search using the MEDLINE database through May 2023. No new literature was identified that would prompt a change in the coverage statement. The key identified literature is summarized below.
 
Chartier-Kastler et al published 3-year results from a prospective, observational, multicenter study from France (SOUNDS) (Chartier-Kastler, 2022). Patients with overactive bladder (N=229) underwent InterStim implantation (either a first device or a replacement) and were followed for a mean of 33.7 ± 3.7 months. During the 3-year follow-up, average daily voids and leaks were significantly reduced (all p<.05) and response (defined as 50% reduction in voids per day or return to normal voiding frequency) ranged from 72% to 86%. Quality of life scores were improved at all study visits. About half of the patients experienced adverse events, which were mostly minor, but surgical revision was required in 33% of patients. Lack of a control arm may limit the clinical applicability of these results.
 
Pezella et al published an observational, single-arm, multicenter study (ARTISAN-SNM) of the Axonics system in 129 patients with urinary urgency incontinence (Pezzella, 2021). After 2 years, 93% of the 121 patients that remained in the study met the criteria for response, which was defined as a 50% reduction in urge incontinence episodes. Freedom from urge incontinence episodes (100% reduction) occurred in 37% of patients. Average number of incontinence episodes per day decreased from 5.6 ± 0.3 at baseline to 1.0 ± 0.3 at 2 years (p<.0001). No serious device-related adverse events occurred.
 
Similarly, Blok et al reported 2-year results of the prospective RELAX-OAB study that evaluated the Axonics system in 51 patients with overactive bladder (Blok, 2020). Response to treatment was defined as a 50% reduction in voids or leaks or a return to normal voiding frequency (<8 voids per day), and was assessed 1 month after implantation. Forty patients were followed for the full 2 years. Of these, 30 patients had met the criteria for response at 1 month and 27 were still responders after 2 years. No serious device-related adverse events occurred.
 
In 2018, the International Continence Society published a best practice statement on the use of sacral neuromodulation (Goldman, 2018). The authors specified that the guideline recommendations applied primarily to the Interstim device and may or may not be applicable to future devices that have become available since that time. For both urinary and bowel disorders, first-line interventions include behavioral therapy, physical therapy, and medical management. Sacral neuromodulation can be offered to patients who fail or have an intolerance to first-line interventions. The guideline also states that sacral neuromodulation is appropriate for interstitial cystitis, bladder pain syndrome, Fowler's syndrome, voiding dysfunction, and nonobstructive urinary retention. However, there was a lack of evidence supporting the use of sacral neuromodulation for chronic pelvic pain unrelated to any of the aforementioned etiologies. For constipation, sacral neuromodulation should only be considered for patients who have had symptoms for at least 1 year, whose symptoms cannot be attributed to a mechanically correctable cause, and when conservative treatment has failed. Contraindications to sacral neuromodulation include lack of response during a therapeutic trial and pregnancy. Relative contraindications may include severe or rapidly progressive neurologic disease, abnormal sacral anatomy, anticipated need for magnetic resonance imaging below the head, and spinal cord injury.
 
In 2020, NICE issued guidance on the Axonics sacral neuromodulation system for treating refractory overactive bladder (NICE, 2020). The guidance states that the Axonics system should be considered an option for people with refractory overactive bladder. Similarly, 2004 guidance states that use of sacral nerve stimulation for urge incontinence and symptoms of urgency/frequency is supported by evidence of efficacy and safety (NICE, 2004).
