J Pannek
The term OAB (overactive bladder) describes a symptom complex. Therefore, initial treatment should be based on clinical symptoms and the results of basic diagnostics. Patient preference is essential for the choice of the initial treatment. Behavioural therapy, electrostimulation and medical treatment are available treatment options. If these are not effective, extended diagnostic examinations should be performed prior to minimally invasive treatments, like onabotulinumtoxin injections in the detrusor or sacral neuromodulation...

Post-prostatectomy urinary incontinence (PPUI) has significant impact on the quality of life of patients who undergo radical prostatectomy. Stress and overflow incontinence may result from the procedure, with sphincteric incompetence and detrusor hypocontractility implicating their development, respectively. In many cases, treatment begins with conservative approaches, including pelvic floor muscle training/biofeedback. Pharmacotherapy can be used to treat overactive bladder. For stress incontinence, transurethral bulking agents are utilized in select patients, however AUS and male slings are the most efficacious options with good success rates...

Intrinsic mechanisms to restrain smooth muscle excitability are present in the bladder, and premature contractions during filling indicate a pathological phenotype. Some investigators have proposed that c-Kit(+) interstitial cells (ICs) are pacemakers and intermediaries in efferent and afferent neural activity, but recent findings suggest these cells have been misidentified and their functions have been misinterpreted. Cells reported to be c-Kit(+) cells colabel with vimentin antibodies, but vimentin is not a specific marker for c-Kit(+) cells...

OBJECTIVE: It is difficult to differentiate multiple system atrophy (MSA) from Parkinson's disease (PD) at least in the early stage. Urodynamic study (UDS) is useful in differentiating MSA from PD. We aimed to clarify which UDS parameter was useful in differentiating MSA from PD. METHODS: We retrospectively reviewed 273 cases and performed UDS and external anal sphincter electromyography (EAS-EMG) in patients with MSA (n=182) and PD (n=91). We analyzed the utility of UDS parameters, including postvoid residuals (PVR), detrusor overactivity (DO), degree of bladder contraction, and mean duration of motor unit potentials (MUPs) in EAS-EMG, for differentiating MSA from PD...

In clinical practice, many patients cannot empty their bladders within an acceptable duration. Common complaints include weak urinary stream and incomplete emptying, which may affect quality of life. Bladder emptying requires sufficient detrusor contractile power, velocity, and durability. The urodynamic term for inadequate detrusor contraction is detrusor underactivity (DU). Although this definition was provided by the ICS, it may not be clinically practical. Analogous to the relationship between overactive bladder (OAB) and detrusor overactivity (DO), the symptom complex caused by DU is termed underactive bladder (UAB)...

INTRODUCTION: The risk of incomplete bladder evacuation requiring catheterization after intravesical onabotulinumtoxinA (BoNT-A) is well established. However, the rates reported in the literature are highly variable and low overall in clinical trials. We attempt to evaluate the rate of symptomatic acute urinary retention requiring catheterization after initial BoNT-A in a private practice setting of patients with idiopathic overactive bladder. METHODS: We performed a retrospective study from 2010 to 2014 for patients with idiopathic overactive bladder undergoing their first BoNT-A...

PURPOSE OF REVIEW: To understand the current literature on age-related neural and detrusor changes associated with overactive bladder symptoms. RECENT FINDINGS: Recent functional magnetic resonance imaging (fMRI) studies have unveiled an age-related decrease in the neural control of continence, represented in the insula, anterior cingulate cortex (ACC) and prefrontal cortex (PFC). Older individuals with overactive bladder symptoms also demonstrate heightened activation of the ACC with low volumes, representing increased bladder sensitivity or sense of urgency...

During filling, urinary bladder volume increases dramatically with little change in pressure. This is accomplished by suppressing contractions of the detrusor muscle that lines the bladder wall. Mechanisms responsible for regulating detrusor contraction during filling are poorly understood. Here we describe a novel pathway to stabilize detrusor excitability involving platelet-derived growth factor receptor-α positive (PDGFRα(+)) interstitial cells. PDGFRα(+) cells express small conductance Ca(2+)-activated K(+) (SK) and TRPV4 channels...

Functional and morphological changes in C-fiber bladder afferent pathways are reportedly involved in neurogenic detrusor overactivity (NDO) after spinal cord injury (SCI). This study examined the morphological changes in different populations of bladder afferent neurons after SCI using replication-defective herpes simplex virus (HSV) vectors encoding the mCherry reporter driven by neuronal cell-type-specific promoters. Spinal intact (SI) and SCI mice were injected into the bladder wall with HSV mCherry vectors driven by the cytomegalovirus (CMV) promoter, CGRP promoter, TRPV1 promoter or neurofilament 200 (NF200) promoter...

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 (NA), are involved in bladder hyperactivity secondary to pBOO. However, little is known about the role of MAO-A, an enzyme oxidizing 5-HT and NA, in the pathogenesis. METHODS Female Sprague Dawley rats were subjected to sham or pBOO operations for 7 days, then their bladders were isolated...

Interstitial cystitis is a chronic disease characterized by lower abdominal pain and some nonspecific symptoms including an increase in urinary frequency and urgency. Sphingosine 1-phosphate (S1P) is a bioactive sphingolipid that controls smooth muscle tone via G-protein coupled receptors (S1P1-3 receptors). S1P production is known to take place both in physiological states and some pathological situations, such as in overactive bladder syndrome. The intracellular mechanism of S1P-induced contractile response was investigated in β-escin permeabilized detrusor smooth muscle of rats having cyclophosphamide-induced cystitis...

AIMS: OnabotulinumtoxinA (onaBNTa) for treating neurogenic detrusor overactivity (NDO) is widely used after its regulatory approval in adults. Although the administration of onaBNTa is still considered off-label in children, data have already been reported on its efficacy and safety. Nowadays, there is a lack of standardized protocols for treatment of NDO with onaBNTa in adolescent patients in their transition from the childhood to the adult age. With the aim to address this issue a consensus panel was obtained...
