Purpose:
The Stoller peripheral neurostimulation (SANS) is a new therapeutic procedure for bladder dysfunction.
Material And Methods:
Each of 11 patients (8 women, 3 men) underwent 12 SANS treatment sessions.
Indications:
overactive bladder (5 patients), chronic nonobstructive urinary retention (3 patients) and pelvic pain (3 patients). Median follow-up was 3 months.
Results:
In 2 overactive bladder patients, the number of voids was reduced by at least 50%. In one patient with chronic retention, residual urine was temporarily decreased to <100 cc. 2 pelvic pain patients reported a slight improvement. In summary, 50% of the patients demonstrated a temporary response. Only 2 overactive bladder patients reported a permanent objective and subjective improvement. No complications were observed.
Conclusion:
As the success rate was low and the procedure is time-consuming, we recommend the SANS procedure only in selected cases. We perform SANS treatment only in patients with overactive bladder refractory to conservative treatment. Prerequisites for a successful treatment is a high patient motivation.
