This study tested the hypothesis that sacral neuromodulation, i.e. electrical stimulation of afferent axons in sacral spinal root, can block pudendal afferent inhibition of the micturition reflex. In α-chloralose anesthetized cats, pudendal nerve stimulation (PNS) at 3-5 Hz was used to inhibit bladder reflex activity while the sacral S1 or S2 dorsal root was stimulated at 15-30 Hz to mimic sacral neuromodulation and to block the bladder inhibition induced by PNS. The intensity threshold (T) for PNS or S1/S2 dorsal root stimulation (DRS) to induce muscle twitch of anal sphincter or toe was determined...

BACKGROUND: Male urinary incontinence adversely affects health-related quality of life and is associated with significant psychosexual and financial burden. The two most common forms of male incontinence are stress urinary incontinence (SUI) and overactive bladder (OAB) with concomitant urge urinary incontinence (UUI). OBJECTIVE: The objectives of this article are to briefly review the current understandings of the pathophysiological mechanisms in SUI and OAB/UUI, and offer a set of practical, action-based recommendations and treatment strategies...

Bladder pain syndrome/interstitial cystitis (BPS/IC) is a common debilitating disease and there has not been consistently effective treatment. We aimed to evaluate all available literature regarding the efficacy and safety of sacral neuromodulation (SNM) for refractory BPS/IC. A comprehensive search of Pubmed, Web of Science and Cochrane Library through May 2016 was conducted. A total of 17 studies enrolling 583 patients were identified. Pooled analyses demonstrated that SNM was associated with great reduction in pelvic pain (weighted mean difference [WMD] -3...

OBJECTIVES: Sacral neuromodulation (SNM) is a well-established treatment for overactive bladder (OAB) and non-obstructive urinary retention (NOR). During test stimulation, the lead is positioned along the third sacral nerve, which ideally results in a response in all four contact points (active electrodes). However, it is unclear whether the position of the lead (depth, angle, deflection) and the number of active electrodes is related to the outcome of SNM. METHODS: All patients who underwent test stimulation using the tined lead between January 2011 and September 2016 were included in this retrospective study...

OBJECTIVE: Sacral neuromodulation (SNM) is proposed to treat different anorectal dysfunctions but its mechanism of action is not yet known. Our previous study demonstrated how SNM can significantly increase neuronal nitric oxide synthase NOS (n-NOS) and inducible NOS (i-NOS) expression in the anus and rectum of rats. There are no reports regarding the relation between SNM and NOS in colonic cells: our aim was to assess NOS expression in colonic rat model after SNM. MATERIALS AND METHODS: Twenty-six female Sprangue-Dawley rats were considered: group I, normal control rats; group II, sham treatment rats, in whom electrodes for electrical stimulation were placed in S1 foramen bilaterally and left in place, without performing neuromodulation; group III, rats in whom SNM was performed...

INTRODUCTION: We aimed to introduce our technique describing the removal of a chronic implanted tined-lead in patients with a sacral neuromodulator implant. MATERIALS AND METHODS: We performed a retrospective review of patients who had chronic sacral neuromodulator (InterStim) implanted by a single surgeon from 2001 through 2015. This simple surgical technique was developed and successfully performed to remove the leads. Primary reasons for removal were elective due to poor symptoms control and failure to maintain response or lead migration...

AIM: Sacral neuromodulation (SNM) is a minimal invasive therapy for functional-constipation (FC) and is most often used to treat adults. Recent studies suggest that SNM may also beneficial in children. However, comparative data regarding preferred age of SNM for FC are lacking. Therefore, long-term results of SNM for FC were compared between children and adults. METHOD: All patients treated with SNM for FC between 2004 and 2015 were evaluated. Outcomes of children (age 10-18 years) were compared with adults (≥18 years)...
