Elderly patients suffering from lower urinary tract symptoms with benign prostatic hyperplasia (BPH) are widely prescribed α1-adrenoceptor blockers (α1-blockers) to improve voiding and storage symptoms. The mechanism of action for improvements in voiding symptoms is well understood; tonus of the urethra and prostate are decreased and urinary flow rate is increased by α1-blockers. However, the mechanisms underlying storage symptoms have remained unclear, although detrusor hyperactivity has been identified as a significant factor...

OBJECTIVE: To investigate changes in expression and activity of monoamine oxidase A (MAO-A) in rats with partial bladder outlet obstruction (pBOO). Previous studies suggested that monoamines, such as serotonin (5-hydroxytryptamine [5-HT]) and noradrenaline, are involved in bladder hyperactivity secondary to pBOO. However, little is known about the role of MAO-A, an enzyme oxidizing 5-hydroxytryptamine and noradrenalin, in the pathogenesis. MATERIALS AND METHODS: Female Sprague Dawley rats were subjected to sham or pBOO operations for 7 days, then their bladders were isolated...

Bladder hyperactivity is described as the presence of "voiding urgency, generally associated with increased daytime frequency and nocturia, with or without urinary incontinence, in the absence of urinary tract infection or other obvious pathology". Onabotulinum toxin A (BTA) is a recommendable therapeutic option in case of failure, contraindication or refusal of the conservative therapy or other non-pharmacological therapies. The injection of BTA in the detrusor has been performed under local, regional or general anesthesia either in the conventional or major ambulatory surgery operative room or in the cystoscopy room...

Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are confirmed to be expressed in bladder interstitial Cajal-like cells (ICC-LCs), but little is known about their possible role in cystitis-associated bladder dysfunction. The present study aimed to determine the functional role of HCN channels in regulating bladder function under inflammatory conditions. Sixty female wild-type C57BL/6J mice and sixty female HCN1-knockout mice were randomly assigned to experimental and control groups, respectively...

BACKGROUND: Neurogenic detrusor hyperactivity (NDH) is a urodynamic observation characterised by involuntary detrusor contractions during the filling phase that are caused by an underlying neurological disease. The common and severe complications that can result from NDH warrant the preparation of healthcare protocols for the proper management of patients with NDH. OBJECTIVE: The aim of this study is to standardise the criteria for the decision-making process in the management of patients with diagnosed or suspected NDH, providing personalised medical care...

INTRODUCTION: Detrusor hyperactivity with impaired contractility (DHIC) is a challenging condition to manage. Sacral neuromodulation (SNM) is a proven treatment modality for both the individual aspects of DHIC. To date, data reporting the outcome of SNM for DHIC are lacking. MATERIALS AND METHODS: Consecutive patients undergoing SNM for DHIC were followed prospectively, from April 2013 to October 2016. Patient demographics, bladder diaries, subjective response rates, ICIQ-OAB, and PGI-I scores were recorded...

Bladder and bowel dysfunction (BBD) describes a spectrum of lower urinary symptoms (LUTS) accompanied by fecal elimination issues that manifest primarily by constipation and/or encopresis. This increasingly common entity is a potential cause of significant physical and psychosocial burden for children and families. BBD is commonly associated with vesicoureteral reflux (VUR) and recurrent urinary tract infections (UTIs), which at its extreme may lead to renal scarring and kidney failure. Additionally, BBD is frequently seen in children diagnosed with behavioural and neuropsychiatric disorders such as attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD)...

EP3 is a receptor for prostaglandin E2 (PGE2), and although its effect on bladder excitability has attracted considerable attention, the underlying mechanism remains unclear. To investigate whether the hyperpolarization-activated cyclic nucleotide-gated (HCN) channels in the interstitial cells of Cajal (ICCs) of the bladder are involved in the effect of EP3 activation on bladder excitability, wild-type mice, HCN1 knockout (HCN1(-/-)) mice and rats were used in our study. Double immunofluorescence staining and immunoprecipitation assays demonstrated the interaction between EP3 and the HCN channels...

AIMS: To investigate the local, regulatory role of the mucosa on bladder strip contractility from normal and overactive bladders and to examine the effect of botulinum toxin A (BoNT-A). METHODS: Bladder strips from spontaneously hyperactive rat (SHR) or normal rats (Sprague Dawley, SD) were dissected for myography as intact or mucosa-free preparations. Spontaneous, neurogenic and agonist-evoked contractions were investigated. SHR strips were incubated in BoNT-A (3 h) to assess effects on contractility...

With increasing age many women suffer from lower urinary tract dysfunction (LUTD) and female sexual dysfunction. An increasing body of evidence supports an association between the 2 conditions. Especially women with urodynamically proved detrusor hyperactivity suffer from sexual dysfunction and there is some evidence that in patients with stress incontinence sexual health improves after successful surgery.

Detrusor underactivity (DU) is defined as a contraction of reduced strength and/or duration during bladder emptying and results in incomplete and prolonged bladder emptying. The clinical diagnosis of DU is challenging when present alone or in association with other bladder conditions such as detrusor overactivity, urinary retention, detrusor hyperactivity with impaired contractility, aging, and neurological injuries. Several etiologies may be responsible for DU or the development of an underactive bladder (UAB), but the pathobiology of DU or UAB is not well understood...
