Abstract
The proper performance of the lower urinary tract is dependent on an intact neural innervation of the individual structures involved. Therefore, any congenital neurological anomalies, diseases, or lesions of the central, peripheral, or autonomic nervous systems can result in lower urinary tract symptoms. Lower urinary tract dysfunction (LUTD) secondary to neurological disorders can significantly reduce quality of life (QoL) and may also give rise to serious complications and psychological and social sequelae. The goals of management of LUTD in patients with neurological disorders are to prevent serious complications and to improve the patient's QoL. Understanding the physiology and pathophysiology of micturition is critical to selecting appropriate treatment options. This article provides an overview of the clinical characteristics, diagnosis, and management of LUTD in patients with certain central and peripheral neuropathies and common lesions.

Abstract
CONTEXT There is a lack of evidence about the efficacy and safety of anticholinergic drugs and about the optimal anticholinergic drug, if any, for the treatment of adult neurogenic detrusor overactivity (NDO). OBJECTIVE Review the current evidence on the efficacy, safety, and tolerability of anticholinergic drugs in the treatment of adult NDO. EVIDENCE ACQUISITION A literature search was conducted from 1966 to May 2011. Meta-analysis of all published randomised controlled trials (RCTs) comparing anticholinergic drugs with placebo and comparing different types, doses, and routes of administration of anticholinergic drugs, in adults with NDO, was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement. The primary outcome was patient-reported cure/improvement of overactive bladder symptoms. Secondary outcomes were quality of life (QoL) changes, bladder diary events, urodynamic outcomes, adverse events, and costs to health services. EVIDENCE SYNTHESIS A total of 960 patients from 16 RCTs with mean follow-up of 3.8 wk were included. Anticholinergic drugs were associated with statistically significantly better patient-reported cure/improvement (risk ratio: 2.80; 95% confidence interval [CI], 1.64 to 4.77), higher maximum cystometric capacity (weighted mean difference [WMD]: 49.49; 95% CI, 15.38 to 84.20), higher volume at first contraction (WMD: 49.92; 95% CI, 20.06 to 79.78), and lower maximum detrusor pressure (WMD: -38.30; 95% CI, -53.17 to -23.43) when compared with placebo. The dry-mouth rates were statistically significantly higher with anticholinergics, with no difference in withdrawals because of adverse events. There was no statistically significant difference in any of the outcomes between oxybutynin and other anticholinergics or among different doses and preparations of anticholinergic drugs. No study reported QoL changes or costs to health services. CONCLUSIONS Compared with placebo, anticholinergic treatment in patients with NDO is associated with better patient-reported cure/improvement and significant reduction of maximum detrusor pressure; however, there is a higher incidence of adverse events. None of the anticholinergic drugs or different dosages assessed in this review was superior to another.

Abstract
Lower urinary tract symptoms (LUTS), overactive bladder, (OAB), and benign prostatic hyperplasia (BPH) are very commonly experienced in men. The mainstay of pharmacotherapy for OAB is the antimuscarinic class of drugs. There has been reluctance to prescribe these agents to men with BPH due to the risk of precipitating urinary retention. Several trials have supported the efficacy and safety of antimuscarinics in treating men with LUTS, alone, or in combination with α-blocker therapy. The combination of 5-α-reductase inhibitors with antimuscarinic agents or surgery are other effective treatments for men with BPH and OAB.

Abstract
Both the physiological role of muscarinic receptors for bladder function and the therapeutic efficacy of antimuscarinic agents for overactive bladder syndrome are well documented. We investigated the effect of antimuscarinic agents with different subtype selectivity on urodynamic parameters in nonhuman primates and rodents and compared plasma levels of these agents between species. Anesthetized rhesus monkeys were transurethrally catheterized, and the bladder was infused with saline. Urodynamic parameters were measured before and after intravenous drug administration. Tolterodine (nonselective) and oxybutynin (moderately M(3)-selective) increased bladder capacity at lower doses than those required to decrease micturition pressure. However, higher doses of darifenacin (M(3)-selective) were needed to increase the bladder capacity than those needed to decrease the micturition pressure. In rats, tolterodine had no effect on the bladder capacity but decreased the micturition pressure at all of the doses administered. Oxybutynin also decreased micturition pressure and increased bladder capacity at the highest dose. Plasma levels of these drugs overlap in both species. These results suggest that, in addition to the M(3) receptor, other muscarinic receptor subtypes contribute to regulate bladder storage function in nonhuman primates, since less subtype-selective tolterodine and oxybutynin showed higher specificity to the bladder capacity effect than the effect on micturition pressure compared with M(3)-selective darifenacin. In addition, the role of muscarinic receptors in bladder storage function varies between primates and rodents. Compared with rodents, muscarinic receptors may play a more active role during the storage phase to regulate the functional bladder capacity in primates.

Abstract
IMPORTANCE OF THE FIELD The use of anticholinergic medication in bladder dysfunction such as overactive bladder syndrome (OAB) is widespread. However, the benefits and risks of anticholinergics in multiple sclerosis (MS) are unclear because in MS the damage to normal urinary function is both more diffuse and increases with disease progression, and the risk of CNS side effects is higher. AREAS COVERED IN THIS REVIEW The pathophysiology of urinary dysfunction in MS and the efficacy and side effects of anticholinergics is assessed. The review analyzed randomized controlled trials and observational studies using anticholinergics involving persons with a confirmed diagnosis of MS having urinary symptoms. Finally a pragmatic approach to managing urinary symptoms in MS is discussed. WHAT THE READER WILL GAIN The published data provide limited evidence for the efficacy of anticholinergics in MS. The complexity of treating urinary symptoms in the context of other therapies and the changing neurological background seen in MS is comprehensively analyzed. TAKE HOME MESSAGE Anticholinergics could be helpful in particular phases of MS. However, there is inadequate evidence currently available on the use of anticholinergics in MS, and further research on the management of the MS neuropathic bladder is warranted.

Abstract
AIMS Adequate urodynamic assessment of bladder behavior is essential in spinal cord injury (SCI) patients. Ambulatory urodynamics are more sensitive to detect detrusor overactivity (DO) than conventional urodynamics. The primary objective of this study was to determine the value of ambulatory urodynamics for the diagnosis of DO in SCI patients compared to conventional urodynamics. METHODS Twenty-seven SCI patients who were suspected of DO underwent both conventional and ambulatory urodynamics at one day. A single involuntary detrusor contraction (IDC) was defined as a detrusor pressure rise of at least 10 cmH(2)O. DO according to the ICS definition was used in addition to minimize the influence of catheter artifacts. Outcome of urodynamics was used for decisions on treatment. RESULTS Ambulatory urodynamics were more sensitive to diagnose IDC and DO. Conventional urodynamics had a sensitivity of 82% and specificity of 75% for DO diagnosis compared to ambulatory urodynamics. Mean maximum detrusor pressures did not differ significantly between both urodynamics. When the maximum detrusor pressure at conventional urodynamics did not exceed 40 cmH(2)O, 83% (10/12) of patients had a mean maximum detrusor pressure under 40 cmH(2)O at ambulatory urodynamics. Although the inter-individual DO diagnostic agreement was lower for ambulatory than conventional urodynamics (58%, K = 0.201 vs. 77%, K = 0552), the treatment agreement was higher for ambulatory urodynamics (58% vs. 42%). CONCLUSIONS Ambulatory urodynamics do not seem necessary for diagnosis and risk assessment in SCI patients suspected for DO when conventional urodynamics are done properly. The exact role of urodynamics in treatment decision remains to be determined.

Abstract
The muscarinic antagonists oxybutynin and trospium are used as spasmolytic agents for the treatment of overactive urinary bladder disease. Recently, it has been shown that trospium, but not oxybutynin, is a substrate of the multidrug efflux carrier P-glycoprotein, but carrier-mediated drug uptake has not been directly analysed for both drugs. However, trospium has been previously shown to exhibit inhibitory potency for the organic cation transporters (OCTs). The aim of the present study was to examine whether trospium and oxybutynin are substrates, i.e. are transported by the human OCTs (hOCT(1), hOCT(2) and hOCT(3)). Therefore, we measured total and specific (decynium-22-sensitive) uptake, and saturation kinetics of the uptake for [(3)H]oxybutynin and [(3)H]trospium in human embryonic kidney (HEK293) cells transiently transfected with the cDNA of hOCT(1), hOCT(2) or hOCT(3). In addition, we determined IC(50) values for inhibition of hOCT-mediated [(3)H]MPP(+) uptake by unlabelled trospium and oxybutynin. Total uptake of [(3)H]oxybutynin was very high in all transfected HEK293 cells and only a small portion was due to specific, decynium-22-sensitive hOCT-mediated uptake. Oxybutynin inhibited [(3)H]MPP(+) uptake by the three hOCTs with IC(50) values between 20 and 130 μM. Direct determination of transport kinetics was measurable only at hOCT(1) with K (m) of 8 μM and V (max) of 484 pmol/mg protein/min. The rank order of affinity (1/IC(50) or 1/K (m)) of specific oxybutynin uptake was hOCT(1) > hOCT(2) = hOCT(3). The observed high non-specific uptake is obviously a consequence of the high lipophilicity of this uncharged drug. Thus, hOCTs may not play a significant role for the overall pharmacokinetics and tissue distribution of oxybutynin. However, and in contrast to oxybutynin, uptake of [(3)H]trospium, an organic cation, was mainly due to carrier-mediated uptake by the three hOCTs. With IC(50) values of 18, 1.4 and 710 μM (at hOCT(1), hOCT(2) and hOCT(3), respectively) and K (m) values of 17 and 8 μM and about identical V (max) values of about 90 pmol/mg protein/min at hOCT(1) and hOCT(2), respectively; the rank order of affinity (1/IC(50) or 1/K (m)) of specific uptake of trospium was hOCT(2) > hOCT(1) > > hOCT(3). Thus, hOCTs very probably contribute to the active tubular and hepatobiliary secretion of trospium. Furthermore, hOCT(1) and hOCT(3) may be involved in the tissue uptake of this drug in the urinary bladder.

Abstract
OBJECTIVES To examine the effects of combined use of trospium chloride and melatonin on in vitro contractility of rat urinary bladder. METHODS Isolated bladder strips from 20 male Wistar rats were examined in an organ bath. Contractions were evoked by acetylcholine (ACh). Initially, effective concentrations of trospium and melatonin to inhibit the contractions were determined. We subsequently tested the effects of combined use of melatonin and trospium on agonist-induced contractions. RESULTS Exposure of bladder strips to 10 microM ACh significantly increased the contractions. After cumulative administration of increasing concentrations of trospium (1, 3, and 5 microM), agonist-induced contractions decreased significantly (P <.05). Similarly, the mean peak amplitude of contractions evoked by ACh was significantly inhibited by melatonin in a concentration-dependent manner (100, 200, and 300 microM) (P <.05). Further evaluation of the effects of combined use of trospium and melatonin on ACh-induced contractions of bladder strips revealed that one-tenth of initially applied dose of trospium (500 nM) in addition to the lowest inhibitory dose of melatonin (100 microM) significantly lowered both the peak amplitude and area under the contractility curve of contractions (P <.05). CONCLUSIONS Our results showed that combined use of low dose trospium and melatonin had strong in vitro inhibitory capability on agonist-induced contractions of rat bladder strips. The present findings may offer an insight into lowering the dose of an antimuscarinic by combining it with an antioxidant and endogenous hormone, melatonin.

Abstract
Pediatric neuropathic bladder dysfunction can cause irreversible renal damage and urinary incontinence. Etiologically, it is usually the consequence of a congenital neural tube defect. The majority of affected children can be successfully managed with the standard medical treatment of clean intermittent catheterization and anticholinergic (typically oxybutynin) medication. A subset of patients experience severe side effects or insufficient suppression of detrusor overactivity on oral oxybutynin. Intravesical instillations offer an effective alternative; this Review considers their indications, administration, safety and efficacy.

Abstract
PURPOSE OF REVIEW To review the most current literature regarding the management of neurogenic bladder in children. RECENT FINDINGS Several recent papers have addressed the investigation and management of children with neurogenic bladder. Bladder wall thickness as measured by ultrasound may identify the children with urodynamic risk factors for upper urinary tract deterioration. Strategies such as maximal anticholinergic therapy, total endoscopic management, conservative management throughout puberty, and isolated bladder neck procedures to avoid bladder augmentation show promise. However, at present, there is inadequate long-term follow-up to recommend widespread application of all of these approaches. As children with neurogenic bladder enjoy longer life spans, issues including risks of malignancy related to augmentation and transition to adult-centered care will continue to gain significance. SUMMARY Pediatric urologists continue to face many challenges in the management of children with neurogenic bladder. This includes identifying predictors of upper urinary tract deterioration, finding efficacious strategies to avoid bladder augmentation, and long-term care. The most recent literature attempts to address these issues. Further prospective studies with adequate follow-up will benefit our understanding of this disease process and help to choose the best strategies to achieve continence and preserve renal function in this population.

Abstract
AIMS Conditional stimulation of dorsal genital nerves suppresses undesired detrusor contractions (UDC) and consequently increases bladder capacity and prevents incontinence. No clinically applicable sensor exists for reliable bladder activity monitoring as a trigger for conditional stimulation. Primary objective of this study was to determine whether bladder sensation concomitant with UDC may be used for spinal cord injury (SCI) patients to trigger neurostimulation in daily life. METHODS Nineteen male and 7 female SCI patients suspected of detrusor overactivity (DO) underwent conventional and 6-hr ambulatory urodynamics. Patients were instructed to do normal daily activities and to activate event buttons of the ambulatory recorder to mark events: physical activity, bladder sensation, micturition or intermittent catheterization, and urinary incontinence. Detection rate was defined as the number of recorded bladder sensation divided by the total number of recorded UDC during ambulatory urodynamics. RESULTS Bladder sensation was reported by 73% of patients in daily life. Only 41% of patients had analyzable bladder sensation concomitant with UDC during ambulatory urodynamics. For ambulatory and conventional urodynamics, mean detection rates were 23% and 72%, respectively, with mean recording delays of 57 and 16 sec after UDC onset, respectively. CONCLUSIONS Bladder sensation only occurs in a small group of SCI patients combined with a rather low detection rate and long reaction time. Therefore, bladder sensation as a trigger for conditional stimulation does not seem to be suitable for SCI patients with DO. Reliable techniques for chronic bladder activity monitoring are a prerequisite for successful clinical application of conditional stimulation.

Abstract
Bladder symptoms in multiple sclerosis (MS) are common and distressing but also highly amenable to treatment. A meeting of stakeholders involved in patients' continence care, including neurologists, urologists, primary care, MS nurses and nursing groups was recently convened to formulate a UK consensus for management. National Institute for Health and Clinical Excellence (NICE) criteria were used for producing recommendations based on a review of the literature and expert opinion. It was agreed that in the majority of cases, successful management could be based on a simple algorithm which includes using reagent sticks to test for urine infection and measurement of the post micturition residual urine volume. This is in contrast with published guidelines from other countries which recommend cystometry. Throughout the course of their disease, patients should be offered appropriate management options for treatment of incontinence, the mainstay of which is antimuscarinic medications, in combination, if necessary, with clean intermittent self-catheterisation. The evidence for other measures, including physiotherapy, alternative strategies aimed at improving bladder emptying, other medications and detrusor injections of botulinum toxin A was reviewed. The management of urinary tract infections as well as the bladder problems as part of severe disability were discussed and recommendations agreed.

Abstract
PURPOSE To evaluate in a prospective study the impact of the "three-drug therapy" (antimuscarinic, alpha-blocker and tricyclic antidepressants) on the treatment of refractory detrusor overactivity (DO). METHODS Data from 27 consented patients with refractory DO were available for study. They were asked to complete a daily urinary chart and underwent urodynamic evaluation (UD) before and 60 days after treatment. Response to treatment was considered the presence of one or less involuntary detrusor contractions (IDC) on post-treatment UD. Statistical analysis was performed with Fisher and Mann-Whitney tests, besides Spearman's correlation. P values <0.05 were considered significant. RESULTS The mean follow-up was 15 months. The comparison of the daily urinary chart before and after treatment showed significant increase on bladder capacity and decreases on urgency, urge-incontinence and frequency. Objective data from UD showed that the mean maximum bladder capacity (MBC) ranged from 200 to 300 mL (P < 0.001) with treatment. The same trend was observed with the other UD variables. When compared to baseline, the questionnaire OAB-v8 showed significant improvement (P < 0.01). Main side effects comprised dry mouth and constipation (40%), with average scores of 5.16 and 3.08, respectively (visual scale from 0 to 10). CONCLUSIONS Triple therapy may be an effective, easily employed and well-tolerated option to refractory DO treatment. More studies are necessary to achieve more consistent data on the matter.
