Long-term outcome of sacral nerve modulation (SNM) patients after implanted pulse generator (IPG) change for fecal incontinence (FI) is unknown. This study reported the outcome and long-term satisfaction after a change of an exhausted IPG, questioning the need to concurrently change the electrode and looking for factors involved in the maintenance of treatment efficiency. ⋯ Paul-Antoine Lehur has a consulting agreement with Medtronic SA. This had no impact with the results of the study. The other authors have no conflict of interests to declare.

Obstetric anal sphincter injuries (OASI) are a major risk factor for fecal incontinence (FI). Neuromodulation is often used as second-line therapy for FI, but evidence for its efficacy is conflicting. We aimed to evaluate the efficacy and predictive factors of posterior tibial nerve stimulation for obstetric anal sphincter injury-induced FI. ⋯ Of a well-defined cohort of females with FI secondary to OASI, 38% responded to posterior tibial nerve stimulation. Much of this improvement may relate to improvement in stool consistency.

To perform a pilot study using transcutaneous electrical nerve stimulation (TENS) on the dorsal genital nerve and the posterior tibial nerve for improving symptoms of female sexual dysfunction (FSD) in women without bladder problems. We hypothesize that this therapy will be effective at improving genital arousal deficits. ⋯ This study provides evidence that transcutaneous stimulation of peripheral nerves has the potential to be a valuable therapeutic tool for women with FSD.

This study is aimed at determining if tibial nerve stimulation (TNS) can modulate both bladder underactivity and overactivity. ⋯ This study indicates that TNS at different frequencies might be used to treat bladder underactivity and overactivity.

Intrathecal (IT) trial is a prognostic interventional pain management procedure employed to determine the potential success of treating intractable pain with an implantable infusion device system. There is a dearth of data regarding trials with continuous infusion of combination therapy (e.g. opioid combined with local anesthetic). The objective of the this study was to determine the overall outcomes of continuous infusion IT trials and factors influencing long-term success of IT therapy in patients with chronic intractable pain post-laminectomy. ⋯ Patients with refractory low back pain due to FBSS who underwent successful combination IT trial with hydromorphone and bupivacaine infused through a temporary IT catheter had significantly improved pain intensity scores following permanent implant. Higher pre-trial MEDD was correlated with higher trial and post-implant opioid doses and higher rates of opioid dose escalation post-implant.
