To assess the effectiveness of percutaneous tibial nerve stimulation (PTNS) on adult patients with overactive bladder syndrome, using a systematic review of randomized controlled trials (RCTs), clinical controlled trials (CCTs), and prospective observational cohort studies. ⋯ PTNS is efficacious for frequency and urgency urinary incontinence. More high quality studies are needed to improve the level of evidence concerning the efficacy of PTNS with regard to urgency and nocturia, to specify patient selection criteria, optimal treatment modalities and long-term effects as well as the effectiveness in more pragmatic trials.

Diabetic cystopathy is typically manifested as bladder voiding dysfunction, and numerous patients are refractory to standard therapy. In this study, we determined whether electrical stimulation (ES) of the sensory branch of the pudendal nerve could engage an augmenting reflex and thereby improve bladder emptying in a diabetic animal model with cystopathy. ⋯ The results of the present study are consistent with the essential role for pudendal sensory feedback in efficient bladder emptying, and electrical activation of the sensory branch of the pudendal nerve was efficient restoring the voiding function in diabetic animals with cystopathy. This could provide an approach to improve bladder emptying in diabetic patients with voiding dysfunction.
