BACKGROUND In earlier studies, one in six adults had overactive bladder which may impair quality of life. However, earlier studies have either not been population-based or have suffered from methodological limitations. Our aim was to assess the prevalence of overactive bladder symptoms, based on a representative study population and using consistent definitions and exclusions. METHODOLOGY/PRI...

The spontaneously hypertensive rat (SHR) has been proposed as an overactive bladder model, driven, at least partially, by alterations in bladder innervation. To assess the functional role of sensory bladder afferents we evaluated the conscious cystometric response to prostaglandin E(2) (PGE(2)) or acetic acid (AA) bladder infusion. SHR demonstrated a hypersensitivity to PGE(2) and AA, as indica...

Rat cystometry is increasingly being used in research on overactive bladder and is a research tool for investigating bladder functions during the storage and voiding phases. Measurement of the pressure in the bladder is an essential part of cystometry, although that pressure is the sum of both detrusor and intra-abdominal pressures. In anesthetic cystometry, measurement of the intra-abdominal p...

PURPOSE The Study of Urgent PC vs Sham Effectiveness in Treatment of Overactive Bladder Symptoms (SUmiT) was a multicenter, double-blind, randomized, controlled trial comparing the efficacy of percutaneous tibial nerve stimulation to sham through 12 weeks of therapy. The improvement in global response assessment, voiding diary parameters, and overactive bladder and quality of life questionnaire...

PURPOSE We quantified and described the economic burden of overactive bladder and stress urinary incontinence in Korea. We calculated direct costs by identifying public and private data sources that contain population-based data on resource utilization by patients with stress urinary incontinence and overactive bladder. METHODS For estimating indirect costs (productivity loss), the human capi...

PURPOSE Cystoscopic intradetrusor injection of botulinum toxin has helped patients with refractory overactive bladder but with the increased risks of urinary tract infection and urinary retention. We assessed whether catheter instillation of 200 U onabotulinumtoxinA formulated with liposomes is safe and effective for the treatment of overactive bladder. MATERIALS AND METHODS This 2-center, do...

Background: This meta-analysis aimed to evaluate the efficacy and safety of tibial nerve stimulation (TNS) anticholinergic drugs (ACDs) for treatment overactive bladder syndrome (OAB).

Imidafenacin is an antimuscarinic agent with high affinity for the M(3) and M(1) muscarinic receptor subtypes and low affinity for the M(2) subtype, and is used to treat overactive bladder. Several animal studies have demonstrated that imidafenacin has organ selectivity for the bladder over the salivary glands, colon, heart, and brain. In Phase I studies in humans, the approximately 2.9-hour el...

PURPOSE We investigated improvements in overactive bladder symptoms and depressive symptoms after solifenacin treatment in overactive bladder patients with or without depressive symptoms. METHODS We performed a prospective study of patients who had been diagnosed with overactive bladder from July 2013 to June 2014. Based on the Beck Depression Inventory questionnaire, the test subjects were d...
