Prevalence of sexual abuse and intimate partner violence in adults with spina bifida.

BACKGROUND: People with disabilities and chronic medical conditions are known to be at higher risk of sexual abuse (SA) and intimate partner violence (IPV). People with spina bifida (SB) are vulnerable, but little is known about the prevalence of abuse in this population. OBJECTIVE: To evaluate the prevalence and risk factors of SA and IPV in adults with SB. METHODS: An anonymous international cross-sectional online survey of adults with SB asked about history of SA ("sexual contact that you did not want") and IPV ("hit, slapped, kicked, punched or hurt physically by a partner"). RESULTS: Median age of the 405 participants (61% female) was 35 years. Most self-identified as heterosexual (85%) and were in a romantic relationship (66%). A total of 19% reported a history of SA (78% no SA, 3% preferred not to answer). SA was more frequently reported by women compared to men (27% vs. 5%, p < 0.001) and non-heterosexual adults compared to heterosexuals (41% vs. 15%, p < 0.001). Twelve percent reported a history of IPV (86% no IPV, 2% preferred not to answer). IPV was more frequently reported by women compared to men (14% vs. 9%, p = 0.02), non-heterosexuals compared to heterosexuals (26% vs. 10%, p = 0.002), and adults with a history of sexual activity versus those without (14% vs. 2%, p = 0.01). CONCLUSION: People with SB are subjected to SA and IPV. Women and non-heterosexuals are at higher risk of both.

Autoestima y calidad de vida en los pacientes con disfunción neurogénica y derivaciones urinarias continentes y/o procedimientos para enemas anterógrados / Self-esteem and quality of life in patients with neurogenic dysfunction and continent urinary diversion and/or procedures for anterograde enemas

Introducción y objetivo La importancia de evaluar la autoestima y la calidad de vida de los pacientes con enfermedades crónicas se ha tornado cada vez más relevante.

The Microbiological Burden of Short-Term Catheter Reuse in Individuals with Spinal Cord Injury: A Prospective Study.

Despite the risk of developing catheter-associated urinary tract infections (CAUTI), catheter reuse is common among people with spinal cord injury (SCI). This study examined the microbiological burden and catheter surface changes associated with short-term reuse. Ten individuals with chronic SCI reused their catheters over 3 days. Urine and catheter swab cultures were collected daily for analysis. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) analyses were used to assess catheter surface changes. Catheter swab cultures showed no growth after 48 h (47.8%), skin flora (28.9%), mixed flora (17.8%), or bacterial growth (5.5%). Asymptomatic bacteriuria was found for most participants at baseline (n = 9) and all at follow-up (n = 10). Urine samples contained Escherichia coli (58%), Klebsiella pneumoniae (30%), Enterococcus faecalis (26%), Acinetobacter calcoaceticus-baumannii (10%), Pseudomonas aeruginosa (6%) or Proteus vulgaris (2%). Most urine cultures showed resistance to one or more antibiotics (62%). SEM images demonstrated structural damage, biofilm and/or bacteria on all reused catheter surfaces. XPS analyses also confirmed the deposition of bacterial biofilm on reused catheters. Catheter surface changes and the presence of antibiotic-resistant bacteria were evident following short-term reuse, which may increase susceptibility to CAUTI in individuals with SCI despite asymptomatic bacteriuria.

Periprocedural antibiotics for urodynamic studies of pediatric neurogenic bladder, empiric or culture-guided? A retrospective cohort study.

INTRODUCTION: Urodynamic studies are fundamental in the care of children with neurogenic bladder. Children with neurogenic bladder who perform clean intermittent catheterization (CIC) are considered a high-risk group for infection after urodynamic studies. Current guidelines are not uniform regarding the duration, type, the need of prophylactic antibiotic treatment or performance of urine culture before urodynamic studies. OBJECTIVE: To assess whether antibiotic prophylactic therapy before urodynamic studies should be empiric or culture-guided in children with neurogenic bladder who perform CIC. STUDY DESIGN: Urine samples were collected from children with neurogenic bladder who require CIC before undergoing a urodynamic study. Urine cultures were collected via sterile urethral catheterization one week before urodynamic studies between 2010 and 2018. Children with signs of urinary tract infection (UTI) or children with bladder augmentation were excluded. Resistance to commonly prescribed periprocedural antibiotic treatments was documented. The probability of antibiotic resistance according to sex, vesicoureteral reflux (VUR) status, consumption of prophylactic antibiotics, and self/caregiver performed CIC was determined by a χ2-test. RESULTS: A total of 278 urine cultures were collected from 185 children with neurogenic bladder. The median age was 8 years (IQR 5-12). The most common etiology for neurogenic bladder was spinal dysraphism (n = 146, 77%). Bacterial growth was detected in 216 (78%) cultures, and the most commonly detected bacterial species was Escherichia. coli (n = 155, 72%). Thirty-six (19%) children had VUR, and 14 of them received continuous prophylactic antibiotics. The probability of resistance to oral antibiotics was amoxicillin (22%), cephalexin (21%), cefuroxime (14%), ciprofloxacin (10%), nitrofurantoin (21%), and sulfamethoxazole/trimethoprim (SMX/TMP) (23%) (See "summary table") No significant differences were found by χ2-test in the probability of resistance to antibiotics according to sex, VUR status, continuous antibiotic prophylaxis or self/caregiver performed CIC. DISCUSSION: The study reveals high resistance level to commonly prescribed oral antibiotic treatments (20-30%). Several studies have challenged the need of routine urine cultures before urodynamic studies due to low risk of post-procedural infection. However, it should be mentioned that not all the patients participating in those studies were with neurogenic bladder or routinely performed CIC. Hence, in this specific group of children, routine urine cultures should not be abandoned. The limitations of the study are: Single-center, retrospective study with no data availability regarding the development of UTI after the urodynamic studies. CONCLUSIONS: Urine cultures of children with neurogenic bladder who require CIC demonstrate significant levels of resistance to commonly prescribed oral antibiotics. These findings support culture-guided periprocedural antibiotic prophylaxis.

Distal renal tubular acidosis presenting with an acute hypokalemic paralysis in an older child with severe vesicoureteral reflux and syringomyelia: a case report.

BACKGROUND: Distal renal tubular acidosis (dRTA) is the most common type of renal tubular acidosis (RTA) in children. Pediatric dRTA is usually genetic and rarely occurs due to acquired issues such as obstructive uropathies, recurrent urinary tract infections (UTIs), and chronic kidney disease (CKD). Although persistent hypokalemia frequently occurs with dRTA, acute hypokalemic paralysis is not frequently reported, especially in older children. CASE PRESENTATION: An eight-year-old girl presented with an acute first episode of paralysis. A physical examination revealed normal vital signs, short stature consistent with her genetic potential, and decreased muscle strength of her upper and lower extremities. Preexisting conditions included stage 4 CKD due to recurrent UTIs, severe vesicoureteral reflux and bilateral hydronephrosis, neurogenic bladder, and multisegment thoracic syringomyelia. Her laboratory work-up revealed hypokalemic, hyperchloremic metabolic acidosis with a normal anion gap. She also had a urine osmolal gap of 1.9 mOsmol/kg with a high urine pH. Intravenous potassium replacement resulted in a complete resolution of her paralysis. She was diagnosed with dRTA and discharged with oral bicarbonate and slow-release potassium supplementation. CONCLUSIONS: This case report highlights the importance of considering dRTA in the differential diagnosis of hypokalemic acute paralysis in children. Additionally, in children with neurogenic lower urinary tract dysfunction and recurrent UTIs, early diagnosis of spinal cord etiology is crucial to treat promptly, slow the progression of CKD, and prevent long-term complications such as RTA.

Synthetic mid-urethral slings for the treatment of stress urinary incontinence in women with neurogenic lower urinary tract dysfunction: a systematic review.

INTRODUCTION AND HYPOTHESIS: The aim of our study was to evaluate the efficiency and safety of synthetic mid-urethral slings (sMUS) for the treatment of stress urinary incontinence (SUI) in women with neurogenic lower urinary tract dysfunction (NLUTD). METHODS: A systematic review was performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. MEDLINE, Embase and Cochrane controlled trials databases were systematically searched from January 1995 to April 2021. Studies including adult women with NLUTD who had a sMUS for SUI were considered for inclusion. Primary outcome was success of the surgery according to study criteria. Secondary outcomes were complications, especially de novo urgency, urinary retention, tape exposure and revision for complications. RESULTS: A total of 752 abstracts were screened and 9 studies were included, representing 298 patients. The mean age was 52 years and median follow-up was 41.3 months. sMUS insertion was successful in 237 patients (79.5%). The median rate of de novo urgency was 15.7% (range 8.3-30%). In patients with spontaneous voiding, the median rate of retention was 19.3% (range 0-46.7%) and 21 out of 26 patients required intermittent self-catheterisation. Four cases of tape exposure were reported, and 8 patients underwent a revision for complications. CONCLUSIONS: This review suggests that sMUS might offer interesting success rates and acceptable morbidity and could be considered for the treatment of SUI in women with NLUTD. Further studies are required to define which patients would be more likely to benefit from this intervention, as well as its place among the other surgical treatments for SUI.

Intravesical injection of onabotulinumtoxinA in neurogenic overactive bladder patients with human T-cell leukemia virus type 1-associated myelopathy: A single-institution case series.

INTRODUCTION: Neurogenic overactive bladder is a main feature of human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis. We successfully performed intravesical onabotulinumtoxinA therapy for refractory neurogenic overactive bladder due to human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis. CASE PRESENTATION: We retrospectively reviewed four neurogenic overactive bladder patients with human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis who underwent bladder wall injections of onabotulinumtoxinA from April to October 2020. All patients were female. Their median age was 66 (range, 63-71) years. They were previously treated with ß3-adrenergic receptor agonists or anticholinergic drugs alone or in combination for ≥12 weeks. However, insufficient results were obtained. After 4 weeks of intravesical onabotulinumtoxinA therapy, overactive bladder symptoms improved and maximum cystometric capacity increased in all cases. CONCLUSION: Intravesical onabotulinumtoxinA therapy may be useful for treating refractory overactive bladder due to human T-cell leukemia virus type 1-associated myelopathy/tropical spastic paraparesis.

Comparison of antegrade and retrograde endoscopic injection techniques for neurogenic sphincteric incontinence in children with neurogenic bladder.

INTRODUCTION/BACKGROUND: Urinary incontinence is common in children with neuropathic bladder. Results of endoscopic injections of bulking agents in the bladder neck are promising but it remains unclear whether they should be performed an antegrade or retrograde fashion. OBJECTIVE: Our aim was to compare the antegrade and retrograde endoscopic injection techniques for the treatment of urinary incontinence. STUDY DESIGN: A prospective study evaluating bladder neck dextranomer-hyaluronic acid polymer injections for urinary incontinence in children with neurogenic bladder was initiated in 1997. Children with normal bladder capacity and compliance and without uncontrolled detrusor overactivity or previous bladder neck surgery were included. Patients were classified as success (dry or significantly improved, the latter defined as no need for more than one pad per day, continent during night, and patient seeking no further treatment) or failure at regular follow-up visits. RESULTS: During 1997-2016, 34 children underwent endoscopic treatment in a retrograde while 17 children in antegrade fashion (mean age 11 years, range 5-20). Most patients (n = 47/51) had neuropathic bladder due to congenital malformations, 13 (25%) had had previous bladder augmentation, and 19 (37%) were in wheelchair. Sex, age, etiology of neurogenic bladder, degree of physical impairment, or era of treatment (1997-2012 vs. 2012-2016) had no influence on success rates (Summary Table). After mean follow-ups of 69 (range 12-156) months, success rates were 71% for the antegrade and 53% for the retrograde technique (p = 0.366). Mean number of injections to obtain success was similar between the techniques (1.4 vs. 1.2). While the proportion of dry patients was similar between the two techniques (35%), the proportion of significantly improved patients tended to be higher after antegrade than retrograde injections (35% vs. 18%, p = 0.181). DISCUSSION: Better visualization of the bladder neck may explain the tendency for improved results of antegrade compared to retrograde technique. Further studies in larger patient samples are needed to define the optimal endoscopic injection technique. CONCLUSION: Long-term results of the antegrade endoscopic bladder neck injections of dextranomer-hyaluronic acid polymer for urinary incontinence in children with neurogenic bladder are promising.

Effects of tibial and parasacral nerve electrostimulation techniques on women with poststroke overactive bladder: study protocol for a randomized controlled trial.

BACKGROUND: Neurogenic bladder (NB) can affect people after stroke episodes. NB features changes in the normal voiding pattern at the bladder filling and emptying phases. Overactive NB is characterized by urgency symptoms, with or without urinary incontinence, caused by NB. This disorder affects many domains of life (physical, social, psychological, domestic, sexual) that limit personal autonomy and degrade the quality of life. Among the several treatments available, the conservative physical therapy intervention through tibial nerve electrostimulation (TNES) and parasacral electrostimulation (PSES) can help improve patient conditions with a smaller number of collateral effects than those of interventions based on medication. The aim of the present study is to compare the effects of TNES and PSES techniques in women with overactive NB after stroke episodes to assess the impact of urinary incontinence in these women, on their number of incontinence episodes, daytime and nocturnal urinary frequency, and quality of life. METHODS: This is a prospective clinical study to compare two randomized groups based on parallel and blind conditions. Forty-four women who have had a stroke episode at least 30 days before the trial and who have developed overactive NB will be recruited for the trial. All patients will be subjected to initial evaluation and randomly divided into two groups, TNES and PSES. Subsequently, the two groups will be subjected to a 12-session intervention protocol, twice a week. A new evaluation will be performed after the intervention. DISCUSSION: The results of this study will contribute to the physiotherapeutic treatment of women with NB after a stroke episode since such results will add information about the benefits of this treatment, urinary control, and the improvements in the quality of life of these women.

Long-term efficacy and safety of solifenacin in pediatric patients aged 6 months to 18 years with neurogenic detrusor overactivity: results from two phase 3 prospective open-label studies.

INTRODUCTION: The standard recommended treatment for neurogenic detrusor overactivity (NDO) is clean intermittent catheterization combined with an antimuscarinic agent. However, the adverse systemic side-effects of oxybutynin, the most widely used agent, are of concern. OBJECTIVE: To evaluate the efficacy and safety of solifenacin in pediatric patients with NDO, aged 6 months-<5 years and 5-<18 years. STUDY DESIGN: Two open-label, baseline-controlled, phase 3 studies were conducted in pediatric patients with NDO. Patients were treated with sequential doses of solifenacin oral suspension (pediatric equivalent doses 2.5-10 mg) for 12 weeks to determine each patient's optimal dose, followed by a fixed dose ≥40-week treatment period. Primary efficacy endpoint was change from baseline in maximum cystometric capacity (MCC) after 24 weeks. Secondary endpoints included bladder compliance, bladder volume until first detrusor contraction (>15 cmH2O), number of overactive detrusor contractions (>15 cmH2O), maximum catheterized volume (MCV)/24 h, and incontinence episodes/24 h. Safety parameters were treatment-emergent adverse events (TEAEs), serious adverse events, laboratory variables, vital signs, electrocardiograms, and ocular accommodation and cognitive function assessments. RESULTS: After 24 weeks, MCC had significantly increased compared with baseline in patients aged 6 months -<5 years and 5-<18 years (37.0 ml and 57.2 ml, respectively; P < 0.001; Fig.). Improvement was also observed after 52 weeks' treatment. Significant changes were observed from baseline to week 24 in all secondary endpoints in both age groups: increase in bladder compliance, increase in bladder volume to first detrusor contraction as a percentage of expected bladder capacity, reduction in the number of overactive detrusor contractions, increase in MCV, and decreased incontinence episodes. TEAEs were mostly mild or moderate, and there were no new drug-related TEAEs compared with adult studies. Age-related improvements were noted in ocular accommodation and cognitive function. DISCUSSION: These long-term multicenter investigations demonstrated the efficacy and safety of solifenacin in pediatric patients with NDO. The observed increases in MCC were clinically relevant and demonstrated that an increase in fluid volume can be accommodated in the bladder prior to reaching intravesical pressures that endanger kidney function and/or are associated with leakage or discomfort. Solifenacin was well tolerated with low incidences of constipation and dry mouth (typically associated with antimuscarinics), central nervous system-related side-effects, and facial flushing. CONCLUSION: Solifenacin was effective and well tolerated in pediatric patients with NDO, aged 6 months-<18 years, suggesting that it is a viable alternative to oxybutynin, the current standard of care.

Traumatic spinal cord injury confers bladder cancer risk to patients managed without permanent urinary catheterization: lessons from a comparison of clinical data with the national database.

PURPOSE: Life expectancy for people with traumatic spinal cord injury (SCI) is increasing due to advances in treatment methods and in neuro-urology. Thus, developing urinary bladder cancer (UBC) is gaining importance. METHODS: Single-centre retrospective evaluation of consecutive in- and out-patient data with spinal cord injury between January 1st, 1998 and December 31st, 2018 was carried out and data were compared with UBC data of the German population from the German Centre for Cancer Registry Data at Robert Koch Institute. RESULTS: A total of 37 (4 female, 33 male) out of 7004 patients with SCI were diagnosed with histologically proven UBC (median follow-up 85 months). Median age at UBC diagnosis was 54.0 years (general population: 74 years). The SCI patients had significantly (p < 0.0001, each) more frequent muscle-invasive tumors (81% ≥ T2) and unfavorable grading (76% G3), compared to the general population. Median survival was 13 months for transitional cell carcinoma (n = 31) and 4 months for squamous cell carcinoma (n = 5) (p = 0.0039), resp. The median survival of the 24 cystectomized patients was 15.0 months. Long-term suprapubic or indwelling catheterization was found in only eight patients for a total of only 5.09% (median 15.5 months) of the latency of all patients. No significant differences for T category and grading were observed between the bladder emptying methods intermittent catheterisation and catheter-free voiding. CONCLUSION: The results indicate that in patients with SCI bladder management even without permanent catheterization represents a considerable risk for the development of UBC.

PURPOSE: OnabotulinumtoxinA has demonstrated efficacy and safety in the treatment of urinary incontinence (UI) associated with neurogenic detrusor overactivity (NDO) and idiopathic overactive bladder (OAB); however, real-world evidence is limited. This postmarketing surveillance study aimed to assess the effectiveness and safety of onabotulinumtoxinA in Korean patients with UI associated with NDO or OAB with an inadequate response or intolerance to anticholinergics. METHODS: Patients received 200 U (NDO) or 100 U (OAB) of onabotulinumtoxinA. Effectiveness (assessed using the validated International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF]) and safety were assessed for 1-4 months after onabotulinumtoxinA administration. RESULTS: Overall, 686 patients (NDO, 161; OAB, 525) comprised the safety population; of these, 612 patients were analyzed for effectiveness. There was a significant decrease (P<0.0001) in the mean (standard deviation) ICIQ-SF scores in the NDO (-6.8±5.5) and OAB (-6.0±6.4) groups after onabotulinumtoxinA administration. A decrease of >5 points from baseline in the ICIQ-SF score was observed in 64.9% and 47.3% of patients in the NDO and OAB groups, respectively. Following treatment, 59.9% in the NDO group and 43.0% in the OAB group were dry. There was no effect of age on effectiveness in either group. Only 10 adverse drug reactions (ADRs) were reported in 5.6% of NDO patients and 20 ADRs in 3.2% of OAB patients. Most ADRs in both groups were related to the lower urinary tract such as dysuria (NDO, 1.2%; OAB, 0.6%) and urinary retention (NDO, 0.6%; OAB, 1.5%). CONCLUSION: Effectiveness and safety of onabotulinumtoxinA in Korea in a real-world setting was demonstrated.

Linguistic Validation of the Intermittent Self-catheterization Questionnaire for Patients With Neurogenic Bladder Who Perform Intermittent Catheterization for Voiding Dysfunction.

PURPOSE: In recent years, the importance of patient satisfaction and quality of life-referred to as patient-related outcomes- has been emphasized, in addition to the evaluation of symptoms and severity through questionnaires. However, the questionnaires that can be applied to Korean patients with neurogenic bladder are limited. Therefore, the current study linguistically validated the Intermittent Self-Catheterization Questionnaire (ISC-Q) as an instrument to evaluate the quality of life of Korean patients with neurogenic bladder who regularly perform clean intermittent catheterization (CIC). METHODS: The validation process included permission for translation, forward translations, reconciliation, backward translation, cognitive debriefing, and proofreading. Two bilingual translators independently translated the original version of the ISCQ into Korean and then combined the initial translations. A third bilingual translator performed a backward translation of the reconciled version into English. Five Korean-speaking patients with neurogenic bladder carried out the cognitive debriefing. RESULTS: During the forward translation process, the 24 questions of the ISC-Q were translated into 2 Korean versions. The terms used in each version were adjusted from the original version to use more conceptually equivalent expressions in Korean. During the backward translation process, several changes were involving substitutions of meaning. In the cognitive debriefing process, 5 patients were asked to complete the questionnaire. All patients agreed that the questionnaire explained their situation well. CONCLUSION: This study presents a successful linguistic validation of the Korean version of the ISC-Q, which could be a useful tool for evaluating treatment satisfaction in patients with neurogenic bladder performing CIC regularly.

Bladder Neuromodulation in Acute Spinal Cord Injury via Transcutaneous Tibial Nerve Stimulation: Cystometrogram and Autonomic Nervous System Evidence From a Randomized Control Pilot Trial.

Aim: Percutaneous tibial nerve stimulation is used to decrease incontinence in chronic neurogenic bladder. We report the findings from a subset of patients in a randomized control trial of transcutaneous tibial nerve stimulation (TTNS) for bladder neuromodulation in acute spinal cord injury (SCI) in whom heart rate variability (HRV) was recorded before and after cystometrogram (CMG). The aim was to correlate autonomic nervous system (ANS) changes associated with the CMG changes after the trial using HRV analyses. Methods: The study was a double-blinded sham-controlled 2-week trial with consecutive acute SCI patients admitted for inpatient rehabilitation, randomized to TTNS vs. control sham stimulation. Pre- and Post- trial CMG were performed with concurrent 5-min HRV recordings with empty bladder and during filling. Primary outcomes were changes with CMG between/within groups and associations to the HRV findings. Results: There were 10 subjects in the TTNS group and 6 in the control group. Pre-trial baseline subject characteristics, blood pressures (BPs), and CMG were similar between groups. In both groups, the pre-trial systolic BP increased during filling CMG. After the trial, the control group had significantly increased detrusor pressure and counts of detrusor-sphincter dyssynergia on CMG, not seen in the TTNS group. Also, the control group did not maintain rising BP post-trial, which was observed pre-trial and remained in the TTNS group post-trial. HRV was able to detect a difference in the ANS response to bladder filling between groups. Post-trial HRV was significant for markers of overall increased parasympathetic nervous system activity during filling in the controls, not seen in the TTNS group. Conclusion: Preliminary evidence suggests that TTNS in acute SCI is able to achieve bladder neuromodulation via modulation of ANS functions.

Intra-bladder wall transplantation of bone marrow mesenchymal stem cells improved urinary bladder dysfunction following spinal cord injury.

BACKGROUND: In the most of previous experiments, intrathecal administration of stem cells (SCs) was seen in the management of neurogenic bladder (NGB) following contusion or complete transaction in the rodent model of spinal cord injury (SCI). Here, we aimed to investigate whether intra bladder wall autologous bone marrow mesenchymal SC (BM-MSCs) transplantation, as a minimally invasive method, could improve bladder dysfunctions after a chronic phase of hemi- and complete-transection SCI in a female rat model. MATERIAL AND METHODS: A total of forty-two female Wistar rats were randomly divided into 6 groups (each in 7) and subjected to complete and incomplete spinal cord transection by a laminectomy at the T9 vertebral level. Four weeks after SCI operation, BM-MSCs (1 × 106/120 µl) were transplanted in six areas of the bladder muscle in rats with complete SCI (cSCI) and hemi SCI (hSCI) groups. In the rats from sham, cSCI and hSCI negative control groups, normal saline was injected instead of BM-MSCs. Four weeks post-cell transplantation, rats were subjected to conscious urodynamic for voiding function assessment. RESULTS: All bladders in cSCI and hSCI groups were the hyperreflexic type. The amplitude of uninhibited contraction in cSCI + BM-MSC group was decreased (p = 0.046). we noted that compliance was recovered in the hSCI + BM-MSCs group (p = 0.041). Residual volume was increased significantly after SCI while cell transplantation decreased this index in both hSCI and cSCI +BM-MSCs groups. The statistically significant result was only seen in the hSCI group (p = 0.046). Data showed that collagen deposition was markedly increased in the SCI group compared to the control or sham groups. These changes were decreased post-treatment in the hSCI group (p = 0.042). CONCLUSION: Our study added a notion that urinary dysfunction associated with SCI, was improved following direct injection of autologous BM-MSC transplantation to bladder wall in the chronic phase of SCI injury.

Neomycin-polymyxin or gentamicin bladder instillations decrease symptomatic urinary tract infections in neurogenic bladder patients on clean intermittent catheterization.

INTRODUCTION: Recurrent urinary tract infections (UTIs) are common in patients with neurogenic bladder (NGB) performing clean intermittent catheterization (CIC) treated with or without oral antibiotic prophylaxis. OBJECTIVE: The authors aim to determine if daily neomycin-polymyxin or gentamicin bladder instillations reduce the rate of symptomatic UTIs, the need for oral antibiotic prophylaxis, emergency department (ED) visits for UTI, and inpatient hospitalizations for UTI in patients with NGB on CIC. The authors also aim to investigate resistance patterns in urine microorganisms in patients treated with antibiotic bladder instillations. STUDY DESIGN: The authors retrospectively reviewed the records of all-age patients cared for in the pediatric urology clinic with NGB on CIC having symptomatic UTIs and on daily intravesical instillations of neomycin-polymyxin or gentamicin between 2013 and 2017. Symptomatic UTIs were defined as a positive urine culture with greater than 10,000 colony forming units/mL associated with one or more of the following patient complaints: cloudy/foul-smelling urine, fevers, chills, increase in bladder spasms, pain, urinary leakage, or physician decision for antibiotic treatment. Multidrug-resistant organisms were resistant to two or more classes of antibiotics. RESULTS: Fifty-two patients with a median age of 14.5 years and 192 distinct urine cultures were identified. 90.4% and 9.6% of patients received neomycin-polymyxin and gentamicin instillations, respectively. After initiation of intravesical antibiotics, the rate of symptomatic UTIs was reduced by 58% (incidence rate ratio [IRR]: 0.42, 95% confidence interval [CI]: 0.31-0.56; P < 0.001), the rate of ED visits was reduced by 54% (IRR: 0.46, 95% CI: 0.30-0.71; P < 0.001), and the rate of inpatient hospitalizations for UTI was reduced by 39% (IRR: 0.61, 95% CI: 0.37-0.98; P = 0.043). Fewer patients received oral antibiotic prophylaxis after initiation of antibiotic instillations (odds ratio: 0.12, 95% CI: 0.02-0.067; P = 0.016). There was a trend toward a decrease in multidrug resistance and no change in gentamicin resistance in urine microorganisms. DISCUSSION: This study describes a feasible alternative treatment for patients with NGB on CIC who have persistent UTIs despite oral antibiotic prophylaxis, and for some patients, it may suggest a possibility of discontinuing oral prophylaxis. Limitations include a retrospective design with a small cohort of patients and varying dosages of neomycin-polymyxin. CONCLUSIONS: Antibiotic bladder instillations appear to decrease frequency of symptomatic UTIs, ED visits for UTI, inpatient hospitalizations for UTI, and the need for oral antibiotic prophylaxis in patients with NGB on CIC. There was no increase in multidrug resistance or gentamicin resistance in UTI organisms with use of intravesical antibiotic instillation.

Safety, Feasibility, and Efficacy of Transcutaneous Tibial Nerve Stimulation in Acute Spinal Cord Injury Neurogenic Bladder: A Randomized Control Pilot Trial.

OBJECTIVES: We investigated whether transcutaneous tibial nerve stimulation (TTNS) in acute spinal cord injury was safe and feasible, and could achieve neuromodulation and improve cystometrogram parameters during acute inpatient rehabilitation. MATERIALS AND METHODS: Participants were consecutive acute traumatic spinal cord injury patients admitted for acute inpatient rehabilitation, randomized to a 2-week trial of TTNS v sham stimulation. Primary outcomes were safety and feasibility of TTNS and secondary outcomes were bladder measures based on pre- and post-TTNS cystometrogram by group and within groups, including bladder capacity, detrusor hyperreflexia, pressures, and detrusor-sphincter dyssynergia, as well as filling sensations and desire to void. The principle investigator and subjects were blinded to treatment allocation. RESULTS: A total of 19 subjects consented to the study and completed the stimulation protocol. Morbidity was similar between groups and compliance was 100% to the TTNS protocol. Based on a lack of rehabilitation interruptions and comments from staff, TTNS was feasible. Post-cystometrogram parameters were significant for lower volumes until sensation in the control group and prolonged volumes until sensation in the TTNS group. The control group had significant changes of increased detrusor-sphincter dyssynergia and decreased bladder capacity. This was not significantly changed in the TTNS group. CONCLUSIONS: TTNS is a safe and feasible modality that can be performed during inpatient rehabilitation of acute traumatic spinal cord injury. Bladder capacity and episodes of detrusor-sphincter dyssynergia significantly worsened in the control group and did not significantly change in the TTNS group, suggesting that TTNS can alter the course of neurogenic bladder via neuromodulation.
