Summary
Sacral nerve stimulator reprogramming needs vary by diagnosis. Patients with urinary retention require more initial adjustments, while interstitial cystitis patients need more post-implantation sessions.
Area of Science:
- Urology
- Neuromodulation
Background:
- Sacral nerve stimulation is increasingly used for interstitial cystitis.
- Reprogramming requirements after sacral nerve stimulator implantation are not well-defined.
- Variability in reprogramming needs based on pre-implantation diagnosis is unknown.
Purpose of the Study:
- To determine overall reprogramming requirements for sacral nerve stimulators.
- To investigate if reprogramming needs differ based on preoperative diagnosis.
Main Methods:
- Retrospective review of 17 patients who underwent sacral nerve stimulator implantation (June 2002-October 2004).
- Analysis of reprogramming sessions during stage 1 (testing) and stage 2 (permanent implantation).
- Comparison of reprogramming frequency across diagnoses: urgency/frequency/incontinence, urinary retention, and interstitial cystitis.
Main Results:
- Average stage 1 reprogramming sessions: 0.9 (urgency/frequency/incontinence), 3.5 (urinary retention), 2.3 (interstitial cystitis).
- Average stage 2 reprogramming sessions at 12-month follow-up: 2.8 (urgency/frequency/incontinence), 3.0 (urinary retention), 6.9 (interstitial cystitis).
- No stimulator removals due to reprogramming failure.
Conclusions:
- Patients with urinary retention may need more reprogramming during the initial testing phase (stage 1).
- Patients with interstitial cystitis appear to require more reprogramming sessions after permanent implantation (stage 2).
