Sacral Neuromodulation: Encouraging Results in Patients With Urinary Tract Dysfunction

Rios LA, Averbeck MA, Franca W, Sacomani CA, Almeida FG, Gomes CM. Initial experience with sacral neuromodulation for the treatment of lower urinary tract dysfunction in Brazil. Int Braz J Urol. 2016 Mar-Apr;42(2):312-20. doi: 10.1590/S1677-5538.IBJU.2014.0603.

Reports continue to emerge regarding the potential usefulness of sacral neuromodulation (SNM) in treating lower urinary tract conditions. In this initial experience, reported by a group in Brazil, there was a high rate of response and encouraging clinical results in a group of 18 patients treated at one of four outpatient surgical centers. The group included 15 patients with overactive bladder, 2 with urinary retention, and 1 with interstitial cystitis/bladder pain syndrome (IC/BPS). Treatment involves implantation of a pulse generator after a test phase; the test phase was successful in 15 of the patients, or about 83% of the whole group. Although the patients were not followed up over the long term, short-term follow-up suggested most of the patients were having good clinical responses after the implant. Of note, the patient with IC/BPS had a 60% improvement in certain urinary symptoms, and reported a 90% improvement in chronic pain after the test phase.
