We present a constrained mixture-micturition-growth (CMMG) model for the bladder. It simulates bladder mechanics, voiding function (micturition) and tissue adaptations in response to altered biomechanical conditions. The CMMG model is calibrated with both in vivo and in vitro data from healthy male rat urinary bladders (cystometry, bioimaging of wall structure, mechanical testing) and applied to simulate the growth and remodeling (G&R) response to partial bladder outlet obstruction (BOO).

Objective: To assess efficacy and tolerability of mirabegron 50mg versus antimuscarinic monotherapies and combination therapies.
Design, Setting, And Participants: Systematic literature review and network meta-analysis of randomised controlled trials (2000-2017) assessing eligible treatments for OAB.
Medical expulsive therapy (MET), in particular α-blockers, have been recommended as supportive medication if observational treatment of a ureteral stone was an option. Over the years, a considerable number of randomized controlled trials (RCT) as well as several meta-analyses have been published on MET, supporting the use of α-blockers. However, several recently published high quality, large, placebo-controlled randomized trials raised serious doubts about the effectiveness of α-blockers.
View Article and Find Full Text PDFImpaired bladder emptying is a well-recognized cause of lower urinary tract symptoms. However, the symptoms produced do not always relate to voiding, and may include frequency, urgency and incontinence. Conversely, the etiology of symptoms of disturbed voiding is not necessarily dependent upon objectively impaired voiding.

Surgical repair is an effective and durable treatment for both conditions. Over the past two decades there has been a trend to enforce or reinforce repairs with synthetic and biological materials.

This review aimed to identify genetic polymorphisms tested for an association with lower urinary tract symptoms or prolapse, and to assess the strength, consistency, and risk of bias among reported associations.
Study Design: PubMed and HuGE Navigator were searched up to May 1, 2014, using a combination of genetic and phenotype key words, including "nocturia," "incontinence," "overactive bladder," "prolapse," and "enuresis.
Context: Although family studies have shown that male lower urinary tract symptoms (LUTS) are highly heritable, no systematic review exists of genetic polymorphisms tested for association with LUTS.
Objective: To systematically review and meta-analyze studies assessing candidate polymorphisms/genes tested for an association with LUTS, and to assess the strength, consistency, and potential for bias among pooled associations.
Evidence Acquisition: A systematic search of the PubMed and HuGE databases as well as abstracts of major urologic meetings was performed through to January 2013.
Aims: To evaluate the utility of the International Prostate Symptom Score (IPSS) and the LUTS Tool when assessing lower urinary tract symptoms (LUTS). Secondary objectives were to examine associations of LUTS and treatment seeking.
Methods: Analyses were performed using EpiLUTS data, a population-based, cross-sectional, Internet survey of men and women (aged ≥40) in Sweden, UK, and US with a sample of 30,000 participants.
Background: Differences in health burden associated with urinary incontinence (UI) subtypes have been previously described, but the majority of studies are in women. Additional research is needed to examine the prevalence and burden of UI subtype including postmicturition incontinence, nocturnal enuresis, coital incontinence, and incontinence for unspecified reasons.
Objective: Examine the burden of UI in men and women in Sweden, the United Kingdom, and the United States.
Context: The use of botulinum toxin A (BoNTA) in the treatment of lower urinary tract dysfunction has expanded in recent years and the off-licence usage list includes neurogenic detrusor overactivity (NDO), idiopathic detrusor overactivity (IDO), painful bladder syndrome (PBS), and lower urinary tract symptoms resulting from bladder outflow obstruction (BOO) or detrusor sphincter dyssynergia (DSD). There are two commonly used preparations of BoNTA: Botox (onabotulinumtoxinA) and Dysport (abobotulinumtoxinA).
Objective: To compare the reported outcomes of onabotulinumtoxinA and abobotulinumtoxinA in the treatment of NDO, IDO, PBS, DSD, and BOO for adults and children.
Objective: • To examine the prevalence and burden of overactive bladder (OAB) with bother in the UK and Sweden compared to OAB without bother and no/minimal OAB/lower urinary tract (LUTS) symptoms, respectively.
Patients And Methods: • A cross-sectional population-representative survey was conducted via the Internet in the UK, Sweden and USA. • Participants rated the frequency and bother of OAB and LUTS.
A classic triad of symptoms (bladder pain, urinary frequency, and urgency) has served to define bladder pain syndrome/painful bladder syndrome/interstitial cystitis (BPS/PBS/IC) syndrome. BPS/PBS/IC is a distinct condition and it is likely that the urgency experienced by these patients differs from that experienced by those with overactive bladder syndrome. It is unclear how best to define urgency in the BPS/PBS/IC setting.
