We reviewed the available studies on efficacy and safety of percutaneous tibial nerve stimulation (PTNS) and sacral nerve modulation (SNM) for overactive bladder (OAB) symptoms not responsive to conservative treatments. We limited our search to randomized trials, in English, with at least 20 adult patients, and 6 mo and 12 wk of follow-up for SNM and PTNS, respectively, published between January 1998 and December 2017. Therapeutic success ranges from 61% to 90% for SNM and from 54% to 79% for PTNS. Both techniques are effective and safe, with no life-threatening adverse effects...

Urinary incontinence and erectile dysfunction are relatively common conditions in the aging male population. Surgical interventions for urinary incontinence include placement of an artificial urinary sphincter (AUS), perineal sling, or sacral nerve stimulator and injections of periurethral bulking agents. Erectile dysfunction can be treated surgically with placement of a penile prosthesis. The complications of these devices can be broadly categorized as device component malposition, malfunction, and infection...

Sacral nerve stimulation (SNS) has been recognised as an effective treatment option for faecal incontinence (FI) when conservative therapy has failed. Refinement of the procedural technique and the use of a curved stylet may improve the functional outcome. AIM: To explore the relationship between lead-model, functional outcome, stimulation amplitude and need for extra visits during the first year of follow-up. METHOD: Patient data from May 2009 to February 2017, which was prospectively collected in a local database, were extracted and analysed for differences between lead model and improvement in incontinence scores, stimulation amplitude and the need for additional visits during the first year of follow-up...

Lower urinary tract dysfunction (LUTD) is common and causes a spectrum of morbidity and decreased quality of life (QoL) for patients. LUTD can range from urinary retention to urge incontinence, and includes a variety of syndromes, with the most common and widely recognized being overactive bladder (OAB). The classic treatments of LUTD and OAB comprise different strategies including behavioral therapies, medications and minimally invasive or invasive surgical procedures. Generally, once patients have tried behavioral modifications and oral medical therapy, and have not experienced adequate relief of their symptoms, the next step is to consider minimally invasive therapies...

Background: Understanding of the prevalence, pathophysiology, and management of fecal incontinence (FI) in inflammatory bowel disease (IBD) patients without an ileal pouch anal anastomosis (IPAA) is suboptimal. We conducted a systematic review and meta-analysis on the prevalence, pathophysiology, and management of primary FI in IBD patients without IPAA. Methods: We searched MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews (1966 through March 2017) for studies on the prevalence, physiology, or management of FI in IBD patients without IPAA...

Electrical stimulation of peripheral nerves controlling the bladder is an alternative, nondestructive medical treatment for urinary incontinence and retention. In this study, we aimed to identify the most efficient sensory and motor spinal nerve roots involved in the micturition reflex. Unilateral L5-S2 dorsal and ventral roots were electrically stimulated, and bladder reflex contractions were recorded under isovolumetric conditions. Repeated stimulation of the L6 and S1 dorsal roots not only abolished bladder reflex contractions but also induced a poststimulation inhibitory effect, whereas repeated stimulation of the L5 and S2 dorsal roots had no effect...

BACKGROUND: Robotic-assisted techniques have been implemented in the surgical treatment of tumors in the pelvis, abdomen, and thorax. In pelvic tumors, robotic-assisted techniques evade the need for sizable surgical exposure, but make stimulation of the nerves of the sacral plexus very difficult. OBJECTIVE: To describe how laparoscopic robotic-assisted surgery can couple with tools such as the nerve stimulator to aid in the resection of presacral masses emanating from the neural elements and potentially improve neurological outcome by preventing inadvertent injury to involved nerves...

The differential diagnosis of anuria in emergency department (ED) is broad. Secondary to intraabdominal mass pressure or infections, symptoms of micturation difficulties or disuria accompanying to back pain may arise with the interruption of sacral nerve stimulation. Here, we report a patient who admitted to ED with back pain and anuria and diagnosed acute appendicitis (AA) after advanced investigation despite of not to have any abdominal pain. A 36-year-old man admitted to our ED with a 6-h history of back pain and urination difficulty...

With increased use of explosive devices in warfare, anal trauma is often seen coupled with more complex pelviperineal injury. While the associated mortality is high, casualties that survive are often left with disabling fecal incontinence from damage to the anosphincteric complex. After resolution of the acute insult, the initial evaluation mandates a thorough physical exam, including endoscopic evaluation with rigid proctoscopy and flexible sigmoidoscopy, as well as adjunctive testing, specifically anal manometry and endoanal ultrasound...

AIMS: Lumbar to sacral rerouting surgery can potentially allow voiding via a skin-central nervous system-bladder reflex pathway. Here, we assessed if this surgery was effective in treating neurogenic bladder dysfunction/sphincter in felines. METHODS: Eight cats underwent spinal cord transection (SCT) at thoracic level 10/11. Unilateral L7 to S1 ventral root anastomosis was performed 1 month later in six cats. Two cats served as transection-only controls. Electrical and manual stimulation of L6-S1 dermatomes, and urodynamics were performed at 3, 5, 7, and 9/10 months post transection...
