Chronic sacral neuromodulation for treatment of neurogenic bladder dysfunction: long-term results with unilateral implants
2001
Abstract Objectives. To investigate the therapeutic value of sacral neuromodulation in patients with neurogenic disorders in whom conservative treatment options were unsuccessful. Neurogenic disorders may result in various forms of lower urinary tract dysfunction. Methods. Twenty-seven patients (19 women, 8 men) aged 18 to 63 years (mean 44.9 years) were subjected to percutaneous test stimulation of the sacral spinal nerves. Their urologic symptoms consisted of bladder storage failure (n = 15) due to detrusor hyperreflexia and/or bladder hypersensitivity, failure to empty due to detrusor areflexia (n = 11), and combined bladder hypersensitivity and detrusor areflexia (n = 1). Twelve patient…
Selective Sacral Nerve Blockade for the Treatment of Unstable Bladders
1987
38 patients with severe urge or urge incontinence, who did not respond to conservative therapy, were treated with selective sacral nerve blockade using a local anesthetic (bupivacaine). 6 patients of this group had definite selective sacral denervation with phenol. In 31 patients a urodynamic study was done previous to the sacral nerve block as well as 10 and 90 min after the injection. Within the first 2-7 weeks the success rate was about 70% in regard to bladder capacity and mean volume at first desire to void. On long-term follow-up (greater than 7 months), the success rate decreased to about 16%. Only 1 patient of the phenol group still has complete detrusor areflexia for now more than …
Die bipolare Stimulation kann die Erfolgsrate des Peripheren Nervenevaluationstests der sakralen Neuromodulation verbessern
2017
Zusammenfassung Fragestellung Die vorliegende Studie vergleicht die unipolare und die bipolare Stimulationstechnik während des Peripheren Nervenevaluationstestes der Sakralen Neuromodulation in einer Kohorte von 100 Patienten mit nicht-neurogenen und neurogenen Harntraktfunktionsstörungen und überprüft die Hypothese, dass die bipolare Technik der unipolaren bezogen auf die Testeffektivität überlegen ist. Material und Methoden In diese Fall-Kontroll-Studie wurden 43 Patienten mit biopolarer und 57 Patienten mit unipolarer Stimulation eingeschlossen. Für die bipolare Stimulation wurden vier Elektroden an S3 und S4 beidseits platziert und die Elektroden von S3 und S4 jeder Seite elektrisch ver…
Transcutaneous sacral nerve stimulation for intraoperative verification of internal anal sphincter innervation.
2017
Background: The current standard for pelvic intraoperative neuromonitoring (pIONM) is based on intermittent direct nerve stimulation. This study investigated the potential use of transcutaneous sacral nerve stimulation for non‐invasive verification of pelvic autonomic nerves. Methods: A consecutive series of six pigs underwent low anterior rectal resection. For transcutaneous sacral nerve stimulation, an array of ten electrodes (cathodes) was placed over the sacral foramina (S2 to S4). Anodes were applied on the back, right and left thigh, lower abdomen, and intra‐anally. Stimulation using the novel method and current standard were performed at different phases of the experiment…
Extracorporeal Stimulation of Sacral Nerve Roots for Observation of Pelvic Autonomic Nerve Integrity: Description of a Novel Methodological Setup.
2017
Introduction: Neurophysiologic monitoring can improve autonomic nerve sparing during critical phases of rectal cancer surgery. Objectives: To develop a system for extracorporeal stimulation of sacral nerve roots. Methods: Dedicated software controlled a ten-electrode stimulation array by switching between different electrode configurations and current levels. A built-in impedance and current level measurement assessed the effectiveness of current injection. Intra-anal surface electromyography (sEMG) informed on targeting the sacral nerve roots. All tests were performed on five pig specimens. Results: During switching between electrode configurations, the system delivered 100% of the set cur…
Management of urinary incontinence in postmenopausal women: An EMAS clinical guide.
2020
INTRODUCTION: The prevalence of urinary incontinence and of other lower urinary tract symptoms increases after the menopause and affects between 38 % and 55 % of women aged over 60 years. While urinary incontinence has a profound impact on quality of life, few affected women seek care. AIM: The aim of this clinical guide is to provide an evidence-based approach to the management of urinary incontinence in postmenopausal women. MATERIALS AND METHODS: Literature review and consensus of expert opinion. SUMMARY RECOMMENDATIONS: Healthcare professionals should consider urinary incontinence a clinical priority and develop appropriate diagnostic skills. They should be able to identify and manage a…
Sacral neurostimulation and neuromodulation in urological practice
2000
The problems associated with treating various forms of lower tract dysfunction by electrical stimulation are reflected in the many years of basic and clinical research in this area. However, better understanding of both neuroanatomy and neurophysiology, and development of new technologies have led to further application of electrical current to restore impaired bladder function. Contemporary knowledge of the potential for both sacral neurostimulation and neuromodulation as a therapeutic option for lower urinary tract dysfunction is reviewed.

The laparoscopic implantation of neuroprothesis (LION) procedure to control intractable abdomino-pelvic neuralgia
2011
Objective. To present different aspects and advantages of the laparoscopic implantation of a peripheral nerve stimulator adjacent to the pelvic nerves, aimed at treating intractable pelvic neuralgia by means of neuromodulation - the laparoscopic implantation of neuroprothesis (LION) procedure. Materials and Methods. We report here a series of three patients with different types and etiologies of chronic pelvic neuralgia who underwent laparoscopy for implantation of a peripheral nerve stimulator for neuromodulation, the first for neuromodulation of the ilioinguinal and pudendal nerves, the second for neuromodulation of the sciatic nerve, and the third for neuromodulation of the sacral nerve …
