Project description:Renal damage and renal failure are among the most severe complications of spina bifida. Over the past decades, a comprehensive treatment strategy has been applied that results in minimal renal scaring. In addition, the majority of patients can be dry for urine by the time they go to primary school. To obtain such results, it is mandatory to treat detrusor overactivity from birth onward, as upper urinary tract changes predominantly start in the first months of life. This means that new patients with spina bifida should be treated from birth by clean intermittent catheterization and pharmacological suppression of detrusor overactivity. Urinary tract infections, when present, need aggressive treatment, and in many patients, permanent prophylaxis is indicated. Later in life, therapy can be tailored to urodynamic findings. Children with paralyzed pelvic floor and hence urinary incontinence are routinely offered surgery around the age of 5 years to become dry. Rectus abdominis sling suspension of the bladder neck is the first-choice procedure, with good to excellent results in both male and female patients. In children with detrusor hyperactivity, detrusorectomy can be performed as an alternative for ileocystoplasty provided there is adequate bladder capacity. Wheelchair-bound patients can manage their bladder more easily with a continent catheterizable stoma on top of the bladder. This stoma provides them extra privacy and diminishes parental burden. Bowel management is done by retrograde or antegrade enema therapy. Concerning sexuality, special attention is needed to address expectations of adolescent patients. Sensibility of the glans penis can be restored by surgery in the majority of patients.

Project description:Vesicoureteral reflux (VUR) is a significant risk factor for pyelonephritis and renal scarring. VUR can occur through a defective ureterovesical junction (UVJ) or an overwhelmed normal UVJ mechanism such as in bladder dysfunction of congenital, acquired, or behavioral etiology. There are numerous causes for the development of a neurogenic bladder from spinal dysraphisms to spinal cord trauma and even centrally based abnormalities in children with apparently normal motor function (inappropriately termed nonneurogenic neurogenic bladder). The foundation of managing reflux in these neurogenic bladders is to maintain low bladder pressures which will commonly mean that compliance will be normal as well. There have been several publications that have shown that if bladder pressures are lowered simply with clean intermittent catheterization and medications that the reflux can resolve spontaneously. Alternatively, the patients that are in need of bladder augmentation can have spontaneous resolution of their reflux with the resulting increase in capacity. Surgical intervention is called for when bladder capacity is adequate and the reflux persists or if it is part of a larger operation to increase capacity and to manage outlet resistance. In some instances, reimplantation is necessary because the ureters interfere with the bladder neck procedure. Aside from open and robotic surgical intervention the use of endoscopic injectable agents is beginning to become more popular especially when combined with intravesical botulinum toxin A injections. Great strides are being made in the management of patients with neurogenic bladders and we are seeing more choices for the urologist to be able to manage these patients.

Project description:ObjectiveTo compare clinical findings and urodynamic parameters according to trabeculation grade and analyze their correlations with trabeculation severity in neurogenic bladder caused by suprasacral spinal cord injury (SCI).MethodsA retrospective chart review was performed of neurogenic bladder caused by SCI. Bladder trabeculation grade was compared with SCI-related clinical parameters and bladder-related urodynamic parameters.ResultsIn SCI patients, factors such as disease duration, bladder capacity, detrusor pressure, peak detrusor pressure values, and compliance were significantly different between different grades of bladder trabeculation, while neurological level of injury, completeness, and detrusor sphincter dyssynergia had no clear relationship with bladder trabeculation grade. In the correlation analysis, vesicoureteral reflux was moderately correlated with trabeculation grade (correlation coefficient 0.433), while the correlation coefficients of disease duration, involuntary detrusor contraction, and bladder filling volume were between 0.3 and 0.4.ConclusionBladder trabeculation with suprasacral-type neurogenic bladder was graded. Although disease duration was positively correlated with bladder trabeculation grade, differences in the neurological level of injury or American Spinal Injury Association Impairment Scale score were not observed. Bladder volume, peak detrusor pressure, compliance, reflex volume, and vesicoureteral reflux also showed significant differences according to trabeculation grade. Vesicoureteral reflux was moderately correlated with trabeculation grade.

Project description:In pediatric patients with neurogenic bladder (NGB), urinary tract evaluation, early diagnosis, and individualized management are important. We aimed to clarify the current status of diagnosis and treatment of NGB in Japanese children. This descriptive, observational, retrospective cohort study using the JMDC claims database included NGB patients aged ≤17 years over a 12-month follow-up period. Of the 1065 pediatric NGB patients, 38.9% had spina bifida. Dermatological and gastrointestinal comorbidities were common in the baseline period. Renal/bladder ultrasound was a commonly performed investigation (38.3%), but urodynamics was infrequently used (3.0%). Of all the overactive bladder medications, anticholinergics were used commonly (17.9% patients), and most patients used anticholinergics alone (without combination therapy). Clean intermittent catheterization (CIC; alone or in combination with medications) was performed in 9.3% of patients, and 3.9% of patients were concomitantly treated with medications. The most common incident complication was lower urinary tract infection (18.1%), which was especially common in patients with open spina bifida (54.1%). Despite guideline recommendations, lower urinary tract dysfunction is not thoroughly evaluated. Adequate understanding of patient status is critical to optimal patient management (behavioral therapy, CIC, and medication) in clinical practice.

Project description:PurposeOnabotulinumtoxinA is a well described treatment of neurogenic overactive bladder. While motor effects on the detrusor muscle have been extensively studied, the sensory effects have not. The aim of this study was to evaluate the impact of intradetrusor onabotulinumtoxinA injection on brain activity in female patients with multiple sclerosis and neurogenic overactive bladder.Materials and methodsWe prospectively studied 12 women with stable multiple sclerosis and neurogenic overactive bladder using concurrent functional magnetic resonance imaging and urodynamic studies prior to and 6 to 10 weeks following onabotulinumtoxinA injection. Individual functional magnetic resonance imaging activation maps at the time of strong urgency were averaged before and after onabotulinumtoxinA injection where areas of significant activation were identified.ResultsAfter onabotulinumtoxinA injection functional magnetic resonance imaging activation increased in the right cingulate body (p = 0.0012), the left posterior cingulate (p = 0.02), the left anterior cingulate (p = 0.0015), the right prefrontal cortex (p = 0.0015), the insula (p = 0.0138) and the pons micturition center (p = 0.05). Sparse areas showed decreased activity, including the left cerebellum (p = 0.001), the left fusiform gyrus (p = 0.065) and the bilateral lentiform nucleus (p = 0.026).ConclusionsIntradetrusor injection of onabotulinumtoxinA appeared to increase the activity of most brain regions known to be involved in the sensation and process of urinary urgency in female patients with multiple sclerosis and neurogenic overactive bladder. To our knowledge this is the first study of its kind to evaluate the possible effects of onabotulinumtoxinA at the human brain level where sensory awareness is located. This activation pattern may be used to further phenotype patients to optimize therapy or determine the sensory effects of onabotulinumtoxinA beyond the bladder.

Project description:Urothelium and Lamina Propria (LP) are considered an integrate sensory system which is able to control the detrusor activity. Complete supra-sacral spinal cord lesions cause Neurogenic Detrusor Overactivity (NDO) whose main symptoms are urgency and incontinence. NDO therapy at first consists in anti-muscarinic drugs; secondly, in intra-vesical injection of botulinum toxin. However, with time, all the patients become insensitive to the drugs and decide for cystoplastic surgery. With the aim to get deeper in both NDO and drug's efficacy lack pathogenesis, we investigated the innervation, muscular and connective changes in NDO bladders after surgery by using morphological and quantitative methodologies. Bladder innervation showed a significant global loss associated with an increase in the nerve endings located in the upper LP where a neurogenic inflammation was also present. Smooth muscle cells (SMC) anomalies and fibrosis were found in the detrusor. The increased innervation in the ULP is suggestive for a sprouting and could condition NDO evolution and drug efficacy length. Denervation might cause the SMC anomalies responsible for the detrusor altered contractile activity and intra-cellular traffic and favour the appearance of fibrosis. Inflammation might accelerate these damages. From the clinical point of view, an early anti-inflammatory treatment could positively influence the disease fate.

Project description:IntroductionUrofacial, or Ochoa, syndrome (UFS) is an autosomal recessive disease featuring a dyssynergic bladder with detrusor smooth muscle contracting against an undilated outflow tract. It also features an abnormal grimace. Half of individuals with UFS carry biallelic variants in HPSE2, whereas other rare families carry variants in LRIG2.LRIG2 is immunodetected in pelvic ganglia sending autonomic axons into the bladder. Moreover, Lrig2 mutant mice have abnormal urination and abnormally patterned bladder nerves. We hypothesized that peripheral neurogenic defects underlie LRIG2-associated bladder dysfunction.MethodsWe describe a new family with LRIG2-associated UFS and studied Lrig2 homozygous mutant mice with ex vivo physiological analyses.ResultsThe index case presented antenatally with urinary tract (UT) dilatation, and postnatally had urosepsis and functional bladder outlet obstruction. He had the grimace that, together with UT disease, characterizes UFS. Although HPSE2 sequencing was normal, he carried a homozygous, predicted pathogenic, LRIG2 stop variant (c.1939C>T; p.Arg647∗). Lrig2 mutant mice had enlarged bladders. Ex vivo physiology experiments showed neurogenic smooth muscle relaxation defects in the outflow tract, containing the urethra adjoining the bladder, and in detrusor contractility. Moreover, there were nuanced differences in physiological outflow tract defects between the sexes.ConclusionPutting this family in the context of all reported UT disease-associated LRIG2 variants, the full UFS phenotype occurs with biallelic stop or frameshift variants, but missense variants lead to bladder-limited disease. Our murine observations support the hypothesis that UFS is a genetic autonomic neuropathy of the bladder affecting outflow tract and bladder body function.

Project description:IntroductionWe aimed to determine if transcutaneous tibial nerve stimulation (TTNS) is effective at treating overactive bladder (OAB) symptoms among neurogenic and non-neurogenic patients.MethodsWe conducted a randomized, double-blind, sham-controlled study. Adult patients were recruited from one of two groups: 1) women with OAB; and 2) patients with neurogenic disease and bladder symptoms. The intervention was stimulation of the posterior tibial nerve, for 30 minutes, three times per week for 12 weeks at home using transcutaneous patch electrodes. The primary outcome was improvement of the patient perception of bladder condition (PPBC). We used ANCOVA (with adjustment for baseline values) and followed the intention-to-treat principle; we reported marginal means (MM) and a p<0.05 was considered significant.ResultsWe recruited 50 patients (OAB n=20, neurogenic bladder n=30); 24 were allocated to the sham group and 26 to the active TTNS group. Baseline characteristics in both groups were similar. At the end of the study, there was no significant difference in the PPBC between sham or active groups: 13% (3/24) of sham patients and 15% (4/26) of active TTNS patients were responders (p=0.77), and the MM of the end-of-study PPBC score was 3.3 (95% confidence interval [CI] 2.8-3.7) vs. 2.9 (95% CI 2.5-3.4), respectively (p=0.30). Similarly, there were no significant differences in secondary outcomes (24-hour pad weight, voiding diary parameters, or condition-specific patient-reported outcomes). The results were similar within the OAB and neurogenic bladder subgroups.ConclusionsTTNS does not appear to be effective for treating urinary symptoms of people with OAB or neurogenic bladder dysfunction.

Project description:PURPOSE:To determine if self-administered transcutaneous tibial nerve stimulation (TTNS) is a feasible treatment option for neurogenic bladder among people with spinal cord injury (SCI) who utilize intermittent catheterization for bladder management. METHODS:Four-week observational trial in chronic SCI subjects performing intermittent catheterization with incontinence episodes using TTNS at home daily for 30 minutes. Those using anticholinergic bladder medications were given a weaning schedule to begin at week 2. Primary outcomes were compliance and satisfaction. Secondary outcomes included change in bladder medications, efficacy based on bladder diary, adverse events, and incontinence quality of life (I-QoL) survey. RESULTS:All 16 subjects who started the study completed the 4-week trial rating TTNS with high satisfaction and easy to use, without discomfort. Twelve of 14 patients (86%) using anticholinergic bladder medications reduced their dosage and maintained similar frequency and volumes of bladder catheterization and incontinence episodes. Bladder medication reduced by approximately 3.2 mg weekly (95% confidence interval, -5.9 to -0.4) and anticholinergic side effects of dry mouth and drowsiness decreased more than 1 level of severity from baseline (P=0.027, P=0.015, respectively). At 4 weeks, total I-QoL score improved by an average of 3.2 points compared to baseline in all domains. CONCLUSION:This pilot trial suggests TTNS is feasible to be performed at home in people with chronic SCI. Participants were able to reduce anticholinergic medication dosage and anticholinergic side effects while maintaining continence, subsequently improving QoL scores. These results advocate for further randomized, controlled trials with longer duration and urodynamic evaluation to assess long-term efficacy.

Project description:IntroductionCongenital Zika Syndrome (CZS) has been associated with microcephaly and other central nervous system abnormalities including areas that have been implicated in the control of the lower urinary tract. As such, this descriptive case series has aimed to investigate whether CZS is linked with neurogenic bladder. Identifying such an association is paramount in the effort to recognize CZS complications that have putative treatment options that could mitigate the impact of CZS in infected children.MethodsFollowing IRB approval, urological assessment was performed in all patients referred to our clinic between June 2016 and May 2017 who presented with confirmed CZS-associated microcephaly. The research protocol consisted of obtaining clinical history, laboratory tests, lower and upper urinary tract ultrasounds, as well as a diagnostic urodynamic evaluation. ZIKA virus infection was previously confirmed by maternal history and positive PCR in babies and mothers. Microcephaly and other central nervous system abnormalities were established based on neurological assessment and associated imaging of the central nervous system (CT head and/or Brain MRI).ResultsTwenty-two consecutive CZS patients were tested and confirmed to have neurogenic bladder. Of the 22 patients assessed, 21 presented with an overactive bladder combined with reduced bladder capacity and elevated detrusor filling pressures. Clinically significant increases in postvoid residual (PVR) were confirmed in 40% of cases while a urinary tract infection (UTI) was identified in 23% of cases.ConclusionNeurogenic bladder, a known treatable health condition, was confirmed in 100% of patients tested in this study, most presenting with high-risk urodynamic patterns known to lead to renal damage when left untreated. Follow up studies are necessary to provide further insight onto long-term disease progression and to investigate the response to standard therapies for neurogenic bladder. Nonetheless, we emphasize the importance of proactive management of neurogenic bladder and prompt referral so as to help mitigate CZS disease burden for patients and their families.
