[Prolonged spinal and sacral neurostimulation in children with pelvic organ dysfunction: preliminary analysis]. / Dlitel'naya spinal'naya i sakral'naya neirostimulyatsiya u detei pri narusheniyakh funktsii tazovykh organov: predvaritel'nyi analiz.

OBJECTIVE: To evaluate the clinical efficacy of long-term spinal and sacral programmable neurostimulation for pelvic organ dysfunction in patients with myelodysplasia and chronic dysfunction of the bladder and rectum. MATERIAL AND METHODS: A retrospective study included 32 children aged 1-17 years (mean 10.7) with myelodysplasia, pelvic organ dysfunction and ineffective therapy including botulinum therapy and exclusion of tethered spinal cord syndrome. All children underwent comprehensive urodynamic examination with analysis of bladder and residual urine volume, mean flow rate, intravesical pressure and total urine volume, as well as electromyographic examination. Examination was carried out before surgery, after 6, 12 and 36 months. We applied urinary diary, NBSS questionnaire and urodynamic examination data. All patients underwent neurological examinations (neurological status, magnetic resonance imaging of the spinal cord, computed tomography and radiography of the spine, electroneuromyography). The study was conducted at the neurosurgical department of the Republican Children's Clinical Hospital in Ufa between 2014 and 2022. There were 32 implantations of epidural neurostimulators for pelvic organ dysfunctions. RESULTS: Patients used epidural spinal and sacral stimulation up to 6 times a day for 10-15 min turning on the pulse generator. This method significantly increased urinary volume, decreased episodes of urinary leakage and fecal incontinence, residual volume after urination and number of periodic catheterizations compared to baseline data. Sixteen patients were very satisfied, 10 ones were moderately satisfied, and 2 patients were not satisfied with therapy. The number of bladder catheterizations per day decreased by 51.1%. Urine volume significantly increased from 131.5±16.1 to 236±16.7 ml, intravesical pressure decreased from 23.5±4.2 to 18.5±2.1 cm H2O (by 20.3%). CONCLUSION: Chronic epidural spinal and sacral stimulation can improve the quality of life in patients with pelvic organ dysfunction. This technique may be effective for pelvic organ dysfunction caused by myelodysplasia.

Acupoint selection rules of acupuncture and moxibustion in treating neurogenic bladder based on data mining. / 基于数据挖掘技术分析针灸治疗神经源性膀胱的选穴规律.

OBJECTIVES: To explore the rules of acupoint selection in the treatment of neurogenic bladder (NB) with acupuncture and moxibustion by using data mining. METHODS: The clinical research literatures on acupuncture treatment of NB were collected from PubMed, Embase, Cochrane Library, CNKI, Wanfang Database, VIP Database and China Biology Medicine from retrieved to January 1, 2023. The acupoint prescription database was established using Excel 2019. SPSS Modeler 18.0 and SPSS Statistics 26.0 softwares were used to conduct the frequency, meri-dians, locations, specific acupoints analysis and association rules analysis, factor analysis, cluster analysis, etc., to explore the characteristics and rules of acupoint selection in acupuncture and moxibustion treatment of NB. RESULTS: Totally 313 papers were included, including 110 acupoints with a total frequency of 1 995. The high-frequency acupoints are Zhongji (CV3), Guanyuan (CV4), Sanyinjiao (SP6), etc. The commonly used meridians are the Bladder Meridian of Foot Taiyang and Conception Vessel. The involved acupoints are mostly located in the lumbosacral region and abdomen, and intersection acupoints, mu-front acupoints and back-shu acupoints are the majority in the specific acupoints. The core acupoints group was analyzed, and 17 groups of association rules, 7 factors and 6 effective cluster groups were obtained. CONCLUSIONS: Acupuncture and moxibustion treatment of NB follows the therapeutic principles of toni-fying the kidney, invigorating the spleen, and soothing the liver. The core acupoints group is CV3-CV4-SP6.

The protein kinase A signaling pathway mediates the effect of electroacupuncture on excessive contraction of the bladder detrusor in a rat model of neurogenic bladder.

BACKGROUND: Neurogenic bladder (NB) is a form of neurological bladder dysfunction characterized by excessive contraction of the bladder detrusor. Protein kinase A (PKA) signaling is involved in the contraction of the detrusor muscle. AIMS: To investigate whether PKA signaling mediates the effect of electroacupuncture (EA) on the excessive contraction of the bladder detrusor in NB. METHODS: Sixty rats were randomly divided into control, sham, NB, NB + EA, and NB + EA + H89 (a PKA receptor antagonist) groups. The modified Hassan Shaker spinal cord transection method was used to generate a NB model. After EA intervention for one week, urodynamic tests were used to evaluate bladder function, hematoxylin and eosin staining was conducted to assess morphological changes, enzyme-linked immunosorbent assay (ELISA) was performed to measure the concentration of PKA, and Western blotting was conducted to measure the protein levels of phosphorylated myosin light chain kinase (p-MLCK)/p-MLC. RESULTS: The results showed that NB resulted in morphological disruption, impairment of urodynamics, and decreases in the concentration of PKA and the protein levels of p-MLCK/p-MLC. EA reversed the changes induced by NB dysfunction. However, the improvement in urodynamics and the increases in the concentration of PKA and the protein levels of p-MLCK/p-MLC were inhibited by H89. CONCLUSION: Our findings indicate that the PKA signaling pathway mediates the beneficial effect of EA on excessive contraction of the bladder detrusor in a rat model of NB.

Timing umbilical therapy in treatment of neurogenic bladder after spinal cord injury based on midnight-noon and ebb-flow doctrine: a randomized controlled trial. / åŸºäºŽå­åˆæµæ³¨ç†è®ºæ‹©æ—¶è„ç–—æ²»ç–—è„Šé«“æŸä¼¤åŽç¥žç»æºæ€§è†€èƒ±ï¼šéšæœºå¯¹ç §è¯•éªŒ.

OBJECTIVES: To observe the clinical efficacy of timing umbilical therapy for neurogenic bladder after spinal cord injury based on the midnight-noon and ebb-flow doctrine. METHODS: Sixty patients with neurogenic bladder after spinal cord injury were randomly divided into a trial group and a control group, with 30 patients in each group. In the trial group, based on the midnight-noon and ebb-flow doctrine, umbilical therapy was given at the time zone, 15:00 to 17:00. In the control group, umbilical therapy was delivered at any time zones except the period 15:00 to 17:00. The herbal plaster was remained on the umbilicus for 4 h each time, once daily. One course of treatment was composed of 2 weeks and the treatment lasted 4 weeks. Before and after treatment, the urodynamic indexes (maximum urinary flow rate [Qmax], maximum detrusor pressure [Pdet-max], residual urine volume [RUV]), voiding diary (average daily number of voiding, average daily number of leakage, average daily voided volume), neurogenic bladder symptom score (NBSS), the score of urinary symptom distress scale (USDS) and the score of World Health Organization quality of life assessment-BREF (WHOQOL-BREF) were compared between the two groups; and the clinical efficacy of the two groups was assessed. RESULTS: After treatment, Qmax, Pdet-max, the average daily voided volume and the scores of WHOQOL-BREF were increased (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the scores of USDS were all reduced (P<0.05) in comparison with those before treatment in the two groups. When compared with those in the control group, Qmax, Pdet-max, the average daily voided volume and the score of WHOQOL-BREF were all higher (P<0.05); and RUV, the average daily number of voiding, the average daily number of leakage, NBSS and the score of USDS were lower (P<0.05) in the trial group. The total effective rate was 96.7% (29/30) in the trial group, higher than that (76.7%, 23/30) in the control group (P<0.05). CONCLUSIONS: Timing umbilical therapy, based on the midnight-noon and ebb-flow doctrine, effectively relieves the symptoms of dysuria and improves the quality of life in patients with neurogenic bladder after spinal cord injury.

Development and Validation of an IoT Neurostimulator for the Treatment of Neurogenic Bladder.

Neurogenic bladder is a dysfunction in the lower urinary tract due to damage to the nervous system. One of the treatments that has shown important results is transcutaneous neuromodulation. The neuromodulation equipment available on the market does not allow remote activation or offer many resources for adjusting the parameters of the generated stimulus, as most devices operate with pre-established parameters in closed packages. For this reason, customizing therapy for each individual can be difficult. Therefore, the objective was to develop and validate a neuromodulation device capable of being remotely programmed and properly monitored. Materials and methods for validating devices were used according to the Brazilian Regulatory Standard (NBR), which deals with general requirements for the basic safety and essential performance of electromedical devices. After verifying the reliability of the device, which was capable of generating a biphasic and symmetrical wave, measured by an oscilloscope, considered safe by the technical requirements, it was tested in a real application. Users reported feeling a comfortable stimulus, similar to other previously used devices, and considered the device easy to use. In this way, it was possible to demonstrate the reliability and validity of the developed device.

Effect of Yiyuan moxibustion on urodynamics and TRPV4/ATP/P2X5 signal pathway of bladder tissue in rats with neurogenic bladder after sacral cord injury. / ç›Šå ƒç¸å¯¹éª¶é«“æŸä¼¤åŽç¥žç»æºæ€§è†€èƒ±å¤§é¼ å°¿æµåŠ¨åŠ›å­¦åŠè†€èƒ±ç»„ç»‡TRPV4/ATP/P2X5信号通路的影响.

OBJECTIVES: To observe the effect of Yiyuan moxibustion on urodynamics and the expressions of transient receptor potential vanilloid 4 (TRPV4), adenosine triphosphate (ATP), tyrosine protein kinase KIT (C-Kit) and adenosine triphosphate receptor P2X5 in bladder tissue of rats with detrusor reflex-free neurogenic bladder (NB) after sacral cord injury (SCI), so as to explore its mechanism in promoting the recovery of urination function of NB rats. METHODS: Female SD rats were randomly divided into sham operation, model, Yiyuan moxibustion, Yiyuan moxibustion+inhibitor (combination) and inhibitor groups, with 12 rats in each group. The model of detruser reflex-free NB after sacral SCI was established by modified Hassan Shaker spinal cord transection method. The behavioral score of Basso Beasttie Bresnahan (BBB) and urodynamic indexes were used to evaluate the model of rats after operation. Fifteen days after modeling, Yiyuan moxibustion was applied to "Shenque" (CV8) and "Guanyuan" (CV4) for 20 min, once daily for 14 days. Rats of the inhibitor and combination groups were given intravesical instillation of HC067047 (1 mL, 1 µmol/L, 30 min). After the interventions, urodynamics was used to evaluate the bladder function of rats. HE staining was used to observe the morphology of bladder tissue. ATP content in bladder tissue was detected by colorimetric method. The positive expression rates of C-Kit and their receptor P2X5 in bladder tissue were observed by immunofluorescence double labeling method, and TRPV4, C-Kit, and P2X5 protein expression levels in bladder tissue were detected by Western blot. RESULTS: Compared with the sham operation group, the maximum bladder capacity and bladder compliance of rats in the model group were increased (P<0.01), the leak point pressure, ATP content, the possitive expression rates of C-Kit and P2X5, and the protein expression levels of TRPV4, C-Kit, P2X5 in bladder tissue were decreased (P<0.01). In comparison with the model and combination groups, the Yiyuan moxibustion group showed a decrease in maximum bladder capacity and bladder compliance (P<0.01), an increase in leakage point pressure, ATP content, the possitive expression rates of C-Kit and P2X5, and TRPV4, C-Kit, and P2X5 protein expression levels (P<0.01, P<0.05)；However, these indicators showed opposite trends in the inhibitor group (P<0.01, P<0.05). CONCLUSIONS: Yiyuan moxibustion can improve the urodynamics and bladder function in rats with bladder detrusor nonreflective after SCI, which may be related to its effect in activating the TRPV4 channel in bladder tissue, promoting the release of ATP from bladder epithelium, thus increasing the expression of bladder Cajal interstitial cells and their purinergic P2X5 receptors.

[Efficacy differences between electroacupuncture and moxibustion for neurogenic bladder after spinal cord injury: a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy between electroacupuncture(EA) and moxibustion for neurogenic bladder (NB) after spinal cord injury (SCI). METHODS: One hundred and twenty patients with NB after SCI were randomly divided into an EA group, a moxibustion group, and an intermittent catheterization group, with 40 patients in each group. The patients in the intermittent catheterization group were treated with routine treatment and intermittent catheterization, while the patients in the EA group and the moxibustion group were treated with additional treatments of EA (discontinuous wave, with a frequency of 1.3-1.6 Hz, and intensity based on patient tolerance) and moxibustion, respectively. The acupoints used in both groups were Zhongji (CV 3) and Guanyuan (CV 4), bilateral Zusanli (ST 36), Yinlingquan (SP 9), and Baliao points. Each session lasted for 30 min, once daily, six times a week, for a total of six weeks.The maximum bladder capacity (MBC), residual urine vdume (RUV), detrusor pressure (Pdet) during the filling phase, bladder compliance (BC), maximum renal pelvis separation width of both kidneys, urine white blood cell count, TCM syndrome score, and World Health Organization quality of life assessment-BREF (WHOQOL-BREF) score were compared before and after treatment in the 3 groups. The number of patients in each group who achieved bladder functional balance was recorded, and the clinical efficacy was assessed after treatment. RESULTS: After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were increased (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, urine white blood cell count, and TCM syndrome scores were decreased (P<0.05, P<0.01). In the intermittent catheterization group, MBC, RUV, maximum renal pelvis separation width of both kidneys, and urine white blood cell count were decreased (P<0.05), while BC and WHOQOL-BREF score were increased (P<0.05) after treatment. After treatment, the MBC, Pdet, BC, and WHOQOL-BREF scores in the EA group and the moxibustion group were higher than those in the intermittent catheterization group (P<0.05), while the RUV and TCM syndrome scores were lower than those in the intermittent catheterization group (P<0.05). Moreover, after treatment, the MBC and Pdet in the moxibustion group were higher than those in the EA group (P<0.05), while the RUV, maximum renal pelvis separation width of both kidneys, and TCM syndrome score in the EA group were lower than those in the moxibustion group (P<0.05). The number of patients who achieved bladder functional balance after treatment in the EA group and the moxibustion group was higher than that in the intermittent catheterization group (P<0.05). The cured and effective rate was 85.0% (34/40) in the EA group and 82.5% (33/40) in the moxibustion group, which were both higher than 65.0% (26/40) in the intermittent catheterization group (P<0.05), there was no significant difference between the EA group and the moxibustion group (P>0.05). CONCLUSION: EA and moxibustion could effectively improve the functional state of bladder in patients with NB after SCI. EA is more effective in reducing residual urine volume and excessive activity of the urethral sphincter, and relieving TCM syndromes, while moxibustion is more effective in increasing the pressure of the detrusor during the filling period and establishing the detrusor reflex.

An evaluation of onobotulinumtoxinA as a therapeutic option for pediatric neurogenic detrusor overactivity.

INTRODUCTION: Neurogenic detrusor overactivity (NDO) results in involuntary detrusor contractions during bladder filling or storage risking transmission of pressure to the upper urinary tracts and/or significant incontinence. The goals of bladder management in children with NDO prioritize the preservation of renal function, prevention of UTIs, and optimizing quality of life. First-line measures include intermittent catheterization and anticholinergic medication. However, when conservative measures fail, surgical intervention may be indicated. Historically, the next step was major reconstructive surgery to create a low-pressure urinary reservoir. The introduction of intravesical botulinum neurotoxin A (BoNT/A) for use in children in 2002 offered a less invasive option for management. However, its exact role is still evolving. AREAS COVERED: This article summarizes the mechanism of action of BoNT/A for management of NDO and evaluates the current literature defining common practice and clinical efficacy in children with NDO. The findings of the recently completed phase III trial for intravesical onabotulinumtoxinA in children are discussed in detail. EXPERT OPINION: As the first BoNT/A approved for use in children with NDO, onabotulinumtoxinA appears to be a safe and less invasive alternative to major reconstructive surgery. However, data defining appropriate patient selection and its role as a long-term treatment option continue to develop.

The impact of antegrade continence enemas on bladder function in patients with neurogenic bladder and bowel.

INTRODUCTION: In neurologically intact children with constipation and lower urinary tract symptoms, treatment of constipation frequently results in improved or resolved lower urinary tract symptoms. The impact of treatment of constipation on bladder function in children with a neurogenic bowel and bladder is not well studied. The objective of this study was to evaluate the impact of antegrade continence enemas (ACE) via Chait tube on urodynamic study (UDS) parameters and urinary continence in patients with neurogenic bowel and bladder (NGB). We hypothesized that following ACE some patients would demonstrate improved UDS parameters and improved urinary continence. MATERIALS AND METHODS: A review of patients with NGB who underwent a cecostomy was performed. Inclusion criteria required UDS within 12 months before and after Chait tube placement and no change in clean intermittent catheterization or anticholinergic medications. UDS parameters assessed included bladder capacity, bladder compliance, and bladder stability. In addition, the frequency of antegrade continence enemas and encopresis were reviewed as was the frequency of UTIs before and after the surgery. RESULTS: 8 children met inclusion criteria, including 5 girls and 3 boys, with a mean (range) age of 8.5 years (5-13). All children were on clean intermittent catheterization and 7 were on anticholinergic medications. The patients demonstrated a significant improvement in constipation and encopresis (p < 0.05). All but 1 patient had resolution of encopresis, and 6 of 7 patients who had constipation before ACE management had a resolution of constipation. 2 patients (25%) developed urinary continence (i.e., dry between CIC), and 2 others had improvement in continence. 3, 2, and 2 patients had urodynamic improvement in bladder capacity, compliance, or stability, respectively. However, no significant improvement in urinary incontinence or UDS parameters was demonstrated for the group overall. DISCUSSION: Our data demonstrate that some children with neurogenic bowel and bladder will have improvement in continence and UDS parameters following the initiation of ACE. Despite significant improvement in constipation and encopresis, the frequency of bladder improvement in this population appears less than that reported in neurologically intact children following treatment of constipation. Confirmatory studies with a larger number of children are needed. However, since constipation appears to negatively impact bladder function in some children with neurogenic bowel and bladder, it is reasonable to try to eliminate significant constipation in these patients before increasing pharmaceutical management of their neurogenic bladder.

Efficacy of the magnetic stimulation of sacral nerve roots combined with Tui-na on neurogenic bladder after spinal cord injury: preliminary short-term results.

OBJECTIVE: Neurogenic bladder (NGB) is a serious complication after spinal cord injury (SCI), a destructive neurological disease. This study focused on exploring the efficacy of the magnetic stimulation of sacral nerve roots combined with Tui-na in treating NGB after SCI. METHODS: One hundred patients with NGB after SCI were studied, and intermittent clean catheterization was performed with a water intake program, and patients were grouped into four groups by the random number table method: general treatment group, Tui-na group, magnetic stimulation group, and combined treatment group. A series of relevant factors (voiding diary, urodynamics, and quality of life scores) and clinical efficacy of patients in the four groups before and after treatment were observed. RESULTS: The magnetic stimulation of sacral nerve roots alone, Tui-na alone, and the combination of both were all effective in improving bladder function and quality of life in patients with NGB after SCI, including improvements in voiding frequency, single urine output, maximum urine output, residual urine output, bladder volume and quality of life scores in patients with NGB after SCI. The efficacy of the magnetic stimulation of sacral nerve roots combined with Tui-na was better than that of the magnetic stimulation of sacral nerve roots alone and the Tui-na alone. CONCLUSION: This research demonstrates that the magnetic stimulation of sacral nerve roots combined with Tui-na treatment could effectively improve the urinary system and the quality of life of patients with NGB after SCI, which is worthy of clinical promotion and application.

Understanding factors influencing primary treatment with intradetrusor onabotulinumtoxinA versus augmentation cystoplasty in patients with spina bifida.

PURPOSE: Surgical interventions in the urologic management of children with neurogenic bladder secondary to spina bifida aim to preserve upper tract function, prevent urinary tract infections, and optimize quality of life. However, since the introduction of intravesical onabotulinumtoxinA (Botox) in the management of these patients, the indications for choosing Botox over augmentation cystoplasty (AC) remain undefined. The objective of this study was to determine which factors lead patients to undergo Botox versus AC as a primary surgical treatment after failing medical management. METHODS: We retrospectively reviewed the records of pediatric patients with myelomeningocele undergoing either primary Botox or primary AC at our institution between 2013 and 2018. We recorded demographic and clinical information. We identified 10 important clinical decision-making factors: bladder trabeculation, vesicoureteral reflux, or hydronephrosis on imaging; end-filling pressure (EFP) ≥40 cm H2O, detrusor overactivity, detrusor-sphincter dyssynergia, or reduced capacity on urodynamic studies; physician-perceived bladder hostility; and patient/family desire for continence and independence. The presence of these factors was compared between patients undergoing either primary Botox or primary AC. RESULTS: We identified 14 and 50 myelomeningocele patients who underwent primary AC and primary Botox, respectively. We found no significant differences in age, sex, race, or history of reconstructive surgery (antegrade continence enema or catheterizable channel). For the 10 decision-making factors, desire for independence/continence (p = <0.001) and reduced capacity (p = 0.002) were significantly associated with AC, while trabeculation (p = 0.006), EFP ≥40 cm H2O (p = 0.029), rising slope (p = 0.019), and physician-perceived hostility (p = 0.012) were significantly more common with Botox. CONCLUSIONS: At our institution, quality of life measures prompted AC over objective urodynamic or imaging findings before attempting Botox. These findings support a shared decision-making approach when considering surgical intervention for neurogenic bladder secondary to myelomeningocele.

Efficacy of peripheral electrical nerve stimulation on improvements of urodynamics and voiding diary in patients with neurogenic lower urinary tract dysfunction: a systematic review and meta-analysis.

BACKGROUND: Peripheral electrical nerve stimulation is a routinely recommended treatment for non-neurogenic overactive bladder but has not been approved for patients with neurogenic lower urinary tract dysfunction (NLUTD). This systematic review and meta-analysis was to elucidate the efficacy and safety of electrostimulation and thus provide firm evidence for treating NLUTD. MATERIALS AND METHODS: We systematically performed the literature search through PubMed, Web of Science, and Cochrane Library databases in March 2022. The eligible studies were identified across the inclusion criteria and the data on urodynamic outcomes, voiding diary parameters, and safety was collected to quantitatively synthesize the pooled mean differences (MDs) with 95% CIs. Subgroup analyses and sensitivity analyses were subsequently used to investigate the possible heterogeneity. This report was achieved in accordance with the preferred reporting items for systematic reviews and meta-analyses statement. RESULTS: A total of 10 studies involving 464 subjects and 8 studies with 400 patients were included for systematic review and meta-analysis, respectively. The pooled effect estimates indicated that electrostimulation could significantly improve urodynamic outcomes, including maximum cystometric capacity (MD=55.72, 95% CI 15.73, 95.72), maximum flow rate (MD=4.71, 95% CI 1.78, 7.65), maximal detrusor pressure (MD=-10.59, 95% CI -11.45, -9.73), voided volume (MD=58.14, 95% CI 42.97, 73.31), and post-void residual (MD=-32.46, 95% CI -46.63, -18.29); for voiding diary parameters, patients undergoing electrostimulation showed lower MDs of incontinence episodes per 24 h (MD=-2.45, 95% CI -4.69, -0.20) and overactive bladder symptom score (MD=-4.46, 95% CI -6.00, -2.91). In addition to surface redness and swelling, no stimulation-related severe adverse events were reported else. CONCLUSIONS: The current evidence demonstrated that peripheral electrical nerve stimulation might be effective and safe for managing NLUTD, whereas more reliable data from large-scale randomized controlled trials are necessary to strengthen this concept.

[Uroflowmetry: A follow-up tool for neurogenic bladder patients treated by transcutaneous tibial posterior stimulation?] / Débitmétrie : outil de suivi chez les patients avec vessie neurologique traités par neurostimulation tibiale postérieure ?

OBJECTIVE: Neurogenic bladders can suffer from overactivity, underactivity or dyssynergia depending on the level of the initial lesion. These symptoms can lead to severe alterations of the upper urinary tract. One of the first-line treatments is the transcutaneous tibial posterior stimulation (TTNS), which was demonstrated to be efficient on urodynamics. But it is an invasive, expensive and sometimes not patient-accepted examination, contrary to the uroflowmetry. The aim of this study is to assess the feasibility of a follow-up with a uroflowmetry when treated by TTNS and show that the maximum flow rate increased after treatment, displaying a better detrusor contraction. METHODS: In total, 38 patients with neurogenic bladder undergoing a 12-weeks TTNS treatment and with 2 uroflowmetries interpretable before and after treatment were included. The maximum flow rate (Qmax), the urinated volume and the post-void residual (PVR) were retrieved from the uroflowmetry, and the USP-score and the urinary discomfort were asked at each appointment. RESULTS: Qmax is increased from 17,53ml/s to 18,26ml/s, as well as the PVR (from 76,97ml to 79,16ml). Urinated volume is decreased from 241,4ml to 193,66ml. Patients feel enhanced after TTNS according to the decrease in the USP-score and the urinary discomfort scale. CONCLUSION: The increase of the cystomanometric capacity and the delay of the detrusor overactivity due to TTNS explains the reduction of the urinated volume and the increase of PVR. Increased Qmax might show a better voluntary bladder contraction, with a restraint due to the lack of abdominal pressure measurement during voiding.

[GAO Wei-bin's clinical experience in treatment of neurogenic bladder with acupuncture].

The paper introduces GAO Wei-bin's clinical experience in acupuncture treatment for neurogenic bladder. In association with the etiology, the location and types of neurogenic bladder and in accordance with nerve anatomy and meridian differentiation, the acupoints are selected accurately in treatment. Four acupoint prescriptions are allocated. For frequent urination and urinary incontinence, the foot-motor-sensory area of scalp acupuncture, Shenshu (BL 23) and Huiyang (BL 35) are used. For all kinds of urine retention, especially the patients who are not suitable for acupuncture at the lumbar region, Zhongji (CV 3), Qugu (CV 2), Henggu (KI 11) and Dahe (KI 12) are selected. For all kinds of urine retention, Zhongliao (BL 33) and Ciliao (BL 32) are applicable. For the patients with both dysuria and urinary incontinence, Zhongliao (BL 33), Ciliao (BL 32) and Huiyang (BL 35) are chosen. In treatment of neurogenic bladder, both biao (root causes) and ben (primary symptoms) are considered, as well as the accompanying symptoms; and electroacupuncture is combined accordingly. During the delivery of acupuncture, the sites where the acupoints located are detected and palpated so as to rationally control the depth of needle insertion and the operation of reinforcing and reducing needling techniques.

Effectiveness and safety of sacral neuromodulation for neurogenic bladder.

BACKGROUND: The treatment of neurogenic bladder (NB) is a challenge because conventional therapy often fails. Sacral neuromodulation (SNM) is a minimally invasive technique and an unconventional treatment for neurogenic bladder. Its research is still in the exploratory stage. The research on its effectiveness and safety is not clear. OBJECTIVE: To assess the effectiveness and safety of sacral neuromodulation (SNM) for neurogenic bladder (NB). METHODS: By searching the PubMed databases and Cochrane Library databases, combined with the method of literature tracing, the clinical researches and works on neurogenic bladder and sacral neuromodulation therapy were collected. Two reviewers independently selected and extracted data, (1) determine whether the study meets the inclusion criteria and exclude the literature that meets the exclusion criteria. (2) Researchers' screening results and data, if there are differences in the results, will be discussed to eliminate the differences. (3) Read the full text of the literature carefully to determine the final literature to be included. (4) The relevant data of 11 independent studies, a total of 291 patients, were systematically reviewed using review manager 5.3 software. RESULTS: This research included 11 independent studies with a total of 291 patients. The improvements of main outcomes before and after SNM therapy were significant: incontinence episodes /24 h (WMD -2.52; 95%CI-3.14-1.90; p <0.001), frequency/24 h (WMD-5.96; 95%CI -6.27，-5.66; p <0.001), voiding volume (WMD 116.09 mL; 95%CI 86.68，145.51; p <0.001), cystometric capacity (WMD 129.84 mL; 95%CI 100.53, 159.15; p <0.001), post-void residual volume (WMD-198.00 mL; 95%CI-264.60, -131.40; p <0.001), clean intermittent self-catheterization/24 h (WMD-2.48; 95%CI -2.96, -2.00; p <0.001). CONCLUSION: This systematic review indicated that the sacral neuromodulation treatment for neurogenic bladder was effective and safe.

Repurposing an ACE Malone Channel for Continent Intermittent Catheterization During Re-augmentation Cecocystoplasty: The MACEtrofanoff Procedure.

OBJECTIVE: To describe a surgical alternative option in select patients with neurogenic bladder and a history of Malone antegrade continence enema (MACE) who now require revision augmentation of the bladder, and/or creation of a new continent catherizable urinary channel (CCC). METHODS: Herein, we describe a novel surgical approach for patients who have had prior MACE creation who subsequently require surgical revision and creation of a new CCC. Rather than the traditional approach of creating a new CCC utilizing bowel, we perform a cecocystoplasty and leave the previously created MACE intact. The prior MACE channel becomes repurposed as the new Mitrofanoff, which we have termed the MACEtrofanoff channel. Concomitant cecostomy tube placement for bowel management can be performed at the time of surgery. RESULTS: We have successfully performed this procedure in 2 patients with good outcomes to date. This technique does not require the sacrifice of the prior appendix channel, nor require the formation of a new stoma and channel. Patients are able to adapt easily to clean intermittent catheterization through a channel they are already familiar with for their prior antegrade enemas. CONCLUSION: In select patients, surgeons should consider the MACEtrofanoff procedure to avoid the added morbidity of further bowel mobilization.

Combined acupuncture and moxibustion therapy for the treatment of neurogenic bladder and bowel dysfunction following traumatic spinal cord injury: A case report.

Neurogenic bladder and bowel are two critical autonomic complications following traumatic spinal cord injury (TSCI). Chronic lower urinary tract and bowel dysfunctions can lead to secondary complications, drastically affect the quality of life and significantly increase the risk of hospital readmission and mortality. Other than symptomatic treatments, a few effective therapies are available. Combined acupuncture and moxibustion therapy has positive effects on improving nerve repair and functional recovery in the early phases following TSCI. However, whether it is effective for TSCI-related chronic urinary and bowel dysfunctions remains unknown. This report presents the case of a 26-year-old male patient who experienced neurogenic bladder and bowel dysfunction following TSCI due to an accidental fall from height for more than 10 months and visited our department for combined acupuncture and moxibustion therapy. After 48 treatment sessions, he regained voluntary urination and defecation to a large extent. Urodynamic testing showed recovered bladder compliance and improved detrusor contractility. Symptom assessment with the Qualiveen Short-Form and neurogenic bowel dysfunction scores demonstrated reduced symptom severity. This case suggests that combined acupuncture and moxibustion therapy might help to restore the physiological functions of the lower urinary and digestive tracts following TSCI and might be a promising alternative for the treatment of neurogenic bladder and bowel dysfunction in patients with TSCI.
