INTRODUCTION: Overactive bladder (OAB) is the most prevalent voiding disorder in childhood, and its main manifestation is urinary urgency. In general, urotherapy and anticholinergics are the first choices of treatment. Parasacral Transcutaneous Electrical Neural Stimulation (PTENS) was introduced as an alternative for the treatment of detrusor overactivity in children, but treatment protocols described to date require several sessions per week or long-lasting sessions, making it difficult for the child to adhere to the treatment...

The vascular supply to the human bladder is derived mainly from the superior and inferior vesical arteries, the latter being directly connected to the internal iliac artery. Aging is associated with an impairment of blood vessel function and changes may occur in the vasculature at the molecular, cellular and functional level. Pelvic arterial insufficiency may play an important role in the development of bladder dysfunctions such as detrusor overactivity (DO) and the overactive bladder syndrome. Chronic ischemia-related bladder dysfunction may progress to bladder underactivity and it would be desirable to treat not only lower urinary tract symptoms (LUTS) induced by chronic ischemia, but also the progression of the morphological bladder changes...

Botulinum toxin A (BoNT-A) has become an important therapeutic tool in the management of refractory overactive bladder (OAB). Over the last decade, there have been growing numbers of patients receiving repeat injections and these outcomes have begun to be reported in large, high-quality cohorts. This article reviews the current evidence for the medium- to long-term use of BoNT-A in adults with idiopathic detrusor overactivity (IDO) receiving repeat injections. We find that medium-term outcomes are encouraging but long-term outcomes are not as extensively reported...

PURPOSE: Low amplitude rhythmic contractions (LARC) occur in detrusor smooth muscle and may play a role in storage disorders such as overactive bladder and detrusor overactivity. The purpose of this study was to determine whether LARC frequencies identified in vitro from strips of human urinary bladder tissue correlate with in vivo LARC frequencies, visualized as phasic intravesical pressure (p ves) waves during urodynamics (UD). METHODS: After IRB approval, fresh strips of human urinary bladder were obtained from patients...

The role of ultrasound imaging in urogynecology is not clearly defined. Despite significant developments in visualization techniques and interpretation of images, pelvic ultrasound is still more a tool for research than for clinical practice. Structures of the lower genitourinary tract and pelvic floor can be visualized from different approaches: transperineal, introital, transvaginal, abdominal or endoanal. According to contemporary guidelines and recommendations, the role of ultrasound in urogynecology is limited to the measurement of post-void residue...

Although the physiological role of muscarinic receptors in bladder function and the therapeutic efficacy of muscarinic antagonists for the treatment of overactive bladder are well established, the role of β3-adrenergic receptors (β3ARs) and their potential as therapeutics is just emerging. In this manuscript, we characterized the pharmacology of a novel β3AR agonist vibegron (MK-4618, KRP-114V) and explored mechanistic interactions of β3AR agonism and muscarinic antagonism in urinary bladder function. Vibegron is a potent, selective full β3AR agonist across species and it dose-dependently increased bladder capacity, decreased micturition pressure and increased bladder compliance in rhesus monkeys...

PURPOSE: Urodynamic studies are crucial to neuropathic bladder management and they often determine surgical intervention. However, current evidence indicates that interpretations show poor agreement across physicians. We sought to determine the interrater reliability of urodynamic interpretation in our practice. We hypothesized that there would be strong correlation among pediatric urologists of similar training in a single academic practice. MATERIALS AND METHODS: We retrospectively identified patients with neuropathic bladder who underwent urodynamics at our institution between 2014 and 2015...

BACKGROUND: Several options exist for managing overactive bladder (OAB), including electrical stimulation (ES) with non-implanted devices, conservative treatment and drugs. Electrical stimulation with non-implanted devices aims to inhibit contractions of the detrusor muscle, potentially reducing urinary frequency and urgency. OBJECTIVES: To assess the effects of ES with non-implanted electrodes for OAB, with or without urgency urinary incontinence, compared with: placebo or any other active treatment; ES added to another intervention compared with the other intervention alone; different methods of ES compared with each other...
