Effects of Electroacupuncture on Urodynamics and Expression of ERK/CREB/Bcl-2 Pathway in Spinal Cord of Rats with Neurogenic Bladder after Suprasacral Spinal Cord Injury / 中国中医药信息杂志

Objective To observe the effects of electroacupuncture at"Ciliao","Zhongji","Sanyinjiao"and"Dazhui"on urodynamics and expression of ERK/CREB/Bcl-2 pathway in spinal cord tissue of neurogenic bladder rats after suprasacral spinal cord injury.Methods Sixty female SD rats randomly selected 24 and divided into blank group and sham-operation group(12 rats in each group),the remaining 36 rats were subjected to surgical modeling.After modeling,rats were randomly divided into the model group and the electroacupuncture group,with 12 rats in each group.The electroacupuncture group received unilateral electroacupuncture stimulation at acupoints"Ciliao","Zhongji","Sanyinjiao",and"Dazhui"for 30 minutes each time,once a day,for 7 consecutive days.After administration,urodynamic testing was performed,HE staining was used to observe the morphology of bladder detrusor tissue,TUNEL method was used to detected apoptosis in spinal cord tissue,Western blot was used to detected expressions of p-ERK1/2,p-CREB,p-p90Rsk,CRE,Bcl-2,and Bax proteins in spinal cord tissue.Results Compared with the sham-operation group,the basal pressure,maximum pressure,and leakage point pressure of the bladder in the model group increased significantly(P<0.01),while the maximum capacity and compliance of the bladder decreased significantly(P<0.01);the structure of bladder smooth muscle cells was severely damaged and disorderly arranged,accompanied by a large amount of inflammatory cell infiltration;the apoptosis rate of spinal cord tissue cells significantly increased(P<0.01),and the expressions of p-ERK1/2,p-p90Rsk,p-CREB,CRE,and Bcl-2 proteins in spinal cord tissue were significantly decreased,while the expression of Bax protein significantly increased(P<0.01).Compared with the model group,the basal pressure,maximum pressure,and leakage point pressure of the bladder in the electroacupuncture group decreased significantly(P<0.05),while the maximum capacity and compliance of the bladder increased significantly(P<0.05,P<0.01);the integrity of bladder smooth muscle cells was enhanced,the degree of cell edema was reduced,and inflammatory cell infiltration was reduced;the apoptosis rate of spinal cord tissue cells was significantly reduced(P<0.05),and the expressions of p-ERK1/2,p-p90Rsk,p-CREB,CRE,and Bcl-2 proteins in spinal cord tissue significantly increased,while the expression of Bax protein was significantly decreased(P<0.05,P<0.01).Conclusion Electroacupuncture can promote the repair of bladder detrusor tissue in rats with neurogenic bladder model after suprasacral spinal cord injury,increase the maximum capacity and compliance of the bladder,alleviate the high pressure state in the bladder,and its mechanism is related to activating the ERK/CREB/Bcl-2 pathway,reducing secondary apoptosis of damaged neurons,effectively improving bladder innervation,and protecting bladder function.

Características clínicas y urodinámicas de las mujeres con detrusor hipoactivo / Clinical and urodynamic features of the hypoactive detrusor in women

RESUMEN Objetivo : Determinar las características clínicas y urodinámicas en mujeres con detrusor hipoactivo (DU). Material y métodos : Estudio de serie de casos de corte transversal, retrospectivo, comparativo, entre 2 grupos de pacientes femeninos con síntomas del tracto urinario inferior (STUI). Grupo 1: pacientes con DU según criterios urodinámicos, presión del del detrusor en el flujo máximo de 30 cm H20 (PdetQmax30) o eficiencia del vaciado de la vejiga (BVE) y grupo 2: pacientes sin DU. Se utilizaron medidas de tendencia central y proporciones para la descripción de los datos y pruebas paramétricas para la comparación entre grupos. Resultados : Ciento cincuenta y cinco pacientes fueron incluidos, 44 con DU (grupo 1) y 111 sin DU (grupo 2), con una media de edad de 60,8 ± 16,3 y 55,7 ± 13,4 respectivamente (p=0,0468). La nicturia (p=0,0061) y el esfuerzo miccional (p=0,000) fueron las únicas variables clínicas que presentaron una diferencia significativa en el análisis bivariado. La media de watts factor (WF) fue 3,2 ± 1,0 y 6,0 ± 2,2 en el grupo 1 y 2 respectivamente (p=0,000), mientras que el promedio de la presión isovolumétrica proyectada 1 (PIP1) fue de 28,0 ± 7,5 y 45,9 ± 11,2 respectivamente (p=0,000).En el análisis multivariado, la edad > 60 años, la nicturia, el esfuerzo miccional, tuvieron asociación significativa con DU. Conclusión : Las variables urodinámicas como PIP1, índice de contracción vesical (BCI), BVE y WF mostraron una diferencia significativa en el análisis bivariado, siendo el WF <5 y BCI <80 las que mejor identifican la presencia de DU en mujeres.

SUMMARY Objective : To describe the clinical and urodynamic features of the hypoactive detrusor (DU) in women. Methods : Cross sectional comparative study between two groups of women with lower tract urinary symptoms. Group 1 were patients with Pdet Qmax 30 or with the bladder emptying efficiency (BVE) criteria, and Group 2 were patients without DU. Central tendency measures and proportions were used to report results and parametric tests were performed to compare groups. Results : 155 patients were included, 44 with DU (Group 1) and 111 without DU (Group 2); mean age was 60,8 ± 16,3 and 55,7 ± 13,4 respectively (p=0,0468). Nocturia (p=0,0061) and micturition effort (p=0,000) were the only variables identified in the bivariate analysis who achieved statistical significance. Mean Watts factor (WF) was 3,2 ± 1,0 y 6,0 ± 2,2 in Group 1 and 2, respectively (p=0,000), while mean projected isovolumetric pressure 1 (PIP1) was 28,0 ± 7,5 and 45,9 ± 11,2, respectively (p=0,000). The multivariate analysis identified age above 60 years, nocturia and micturition effort associated with DU. Conclusion : Urodynamic parameters such as PIP1, BCI, BE and WF showed significant difference in the bivariate analysis, WF<5 and BCI <80 are best predictors of DU.

Clinical and Urodynamic results of the Argus T® sling in moderate and severe male stress urinary incontinence after radical prostatectomy - a 5 year prospective study

ABSTRACT Purpose: Sling as a therapeutic option for male stress urinary incontinence (SUI) has been reviewed in the last two decades, as it is a relatively simpliest surgery compared to artificial urinary sphincter and has the ability to modulate urethral compression. This study aims to evaluate the efficacy, rate of complications, quality of life and the effects on bladder emptying of the Argus T® compressive and ajustable sling in moderate and severe male SUI treatment. Materials and Methods: Men eligible for stress urinary incontinence treatment after radical prostatectomy were recruited and prospectively evaluated, from March 2010 to November 2016. It was selected outpatient men with moderate and severe SUI, after 12 months of radical prostatectomy, who have failed conservative treatment. All patients had a complete clinical and urodynamic pre and post treatment evaluation, by means of clinical history, physical examination, urine culture, 1-hour pad test and ICIq-SF questionnaire. The UDS was performed after 12, 18 and 24 months postoperatively. Results: Thirty-seven men underwent sling surgery, 19 patients (51.4%) with moderate and 18 (48.6%) with severe SUI. The minimum follow-up time was 5 years. Overall, we had a success rate of 56.7% at 60 months follow-up. After surgery, we did not observe significant changes in the urodynamic parameters evaluated during the follow-up. No patient had urodynamic bladder outlet obstruction (BOO) after sling implantation. Readjustment of the Argus T® sling was performed in 16 (41%) of the patients and 51% of the patients reported some adverse event. Conclusion: We demonstrate a long-term efficacy and safety of Sling Argus T® as an alternative to moderate and severe male SUI treatment. Furthermore, in our study bulbar urethra compression does not lead to bladder outlet obstruction.

Important role of urodynamic study in improving the diagnosis and treatment of pediatric neurogenic bladder / 现代泌尿外科杂志

Of the common urinary dysfunctions in children, pediatric neurogenic bladder (PNB) is the most challengeable abnormality. It is well known that PNB is mostly caused by dysplasia of the lumbosacral spinal cord and nerves, which seriously affects the quality of life and the physical and mental health of children. The clinical symptoms are not obvious in minor cases, but severe upper urinary tract damage occurs in severe cases. Urodynamic study (UDS) is the best way to detect and determine the type of dysfunction at an early stage, and can guide the formulation of accurate and individualized treatment protocol. However, UDS in children has not been popularized in China, which seriously affects the level of diagnosis and treatment of PNB. This article reviews the importance of UDS so as to provide reference for the diagnosis and treatment of PNB.

Urodynamic evaluation of functional urinary incontinence in children / 现代泌尿外科杂志

Pediatric urinary incontinence (PUI) is common in clinical practice and seriously affects the quality of life as well as physical and mental health of patients. PUI is a multi-factorial related abnormality, very complex in etiology and types. The occurrence of PUI is mostly associated with abnormal vesicourethral function. Urodynamic examination (UDS) is the golden standard to assess voiding function and diagnose the type of bladder and urethral function in children with PUI. UDS of PUI is of great clinical value in determining the cause, making treatment protocol as well as evaluating the therapeutic response. However, UDS in children has not been popularized in China, which seriously affects the diagnosis and treatment of PUI. This article reviews the research progress in the clinical application of UDS in the evaluation of PUI, in order to provide reference for improving the diagnosis and treatment of this disease.

Reference values for urinary flow rate in elderly women: based on a national multicenter study / 中华老年医学杂志

Objective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.

Efficacy differences between electroacupuncture and moxibustion for neurogenic bladder after spinal cord injury: a randomized controlled trial / 中国针灸

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.

Impact of deep resection of endometriosis in the pelvis on urodynamic parameters

Purpose: To evaluate the effects of deep resection of endometriosis in the posterior pelvic region on urodynamic parameters. Methods: A prospective observational study conducted with female patients diagnosed with deep pelvic endometriosis before and after endometriosis resection surgery. Clinical history, image exams, the Female Lower Urinary Tract Symptoms questionnaire, urodynamic examination, cystometry, and voiding study were evaluated. Results: Patients aged 30-39 years old, operative duration of 132.5 minutes, and 2.7 days of hospital stay. Uroflowmetry and cystometry showed tendency for an increase after the surgery in the flow duration, time to maximum flow, and first voiding desire and decreased residual volume and maximum cystometric capacity. Opening, maximum urinary flow, and maximum flow pressure decreased at T1, and the closing parameters increased, although statistically non significant. The variables decreased at T1 in the urodynamic, except for detrusor overactivity. Although we observed a reasonable number of low bladder compliance and abnormal bladder sensation, the results were maintained at T1. General scores for filling and incontinence showed a significant decrease after surgery. Conclusions: A significant response in the patient's perception of urinary function was demonstrated after surgery. It is observed that the surgical procedure did not affect the uroflowmetric and cystometric characteristics of the evaluated patients.

Use of Urodynamics by Gynecologists and Urologists in Brazil / Uso da urodinâmica por ginecologistas e urologistas no Brasil

Abstract Objective Urodynamic studies (UDSs) are a set of tests that assess the storage and emptying of urine, and they are widely used by gynecologists and urologists in the management of urinary incontinence (UI), despite the discussion about its indications. The objectives of the present study were to verify whether UDSs are routinely used in the conservative and surgical approaches to female UI, their other clinical indications, and to compare the responses of Brazilian gynecologists and urologists. Methods The present is an opinion survey applied from August 2020 to January 2021 through a semistructured questionnaire about the clinical practice sent by e-mail to all participants. The responses were compared through statistical analyses. Results Of the 329 participants, 238 were gynecologists (72.3%) and 91, urologists (27.7%). Most gynecologists (73.5%) and urologists (86.6%) do not request UDSs before the conservative treatment of UI; but UDSs are indicated in the preoperative period of anti-incontinence surgeries. Most participants request UDSs in the initial approach to overactive bladder (gynecologists: 88.2%; urologists: 96.7%), and the urologist has greater chance to request this study (odds ratio [OR] = 3.9). For most participants, it is necessary to request uroculture before the UDSs. Conclusion Most Brazilian gynecologists and urologists who participated in the present study do not request UDSs before the conservative treatment of UI, according to national and internacional guidelines, and often request it before the surgical treatment for female UI. The indication of this exam in the initial approach of idiopathic overactive bladder should be reviewed by the participants.

Resumo Objetivo O estudo urodinâmico (EU) é um conjunto de exames que avalia o armazenamento e esvaziamento da urina, e é amplamente utilizado por ginecologistas e urologistas no manejo da incontinência urinária (IU), apesar das discussões sobre suas indicações. O objetivo deste estudo foi verificar se a urodinâmica é rotineiramente utilizada nas abordagens conservadora e cirúrgica da IU feminina, além de outras de suas indicações clínicas, e comparar as respostas de ginecologistas e urologistas brasileiros. Métodos Trata-se de uma pesquisa de opinião, realizada entre agosto de 2020 e janeiro de 2021, por meio de questionário semiestruturado composto por perguntas sobre a prática clínica enviado por e-mail a todos os participantes. As respostas foram comparadas mediante análises estatísticas. Resultados Dos 329 participantes, 238 eram ginecologistas (72,3%) e 91, urologistas (27,7%). A maioria dos ginecologistas (73,5%) e urologistas (86,6%) não solicita EU antes do tratamento conservador da IU; mas o EU é indicado no pré-operatório de cirurgias para IU. A maioria dos participantes solicita EU na abordagem inicial da bexiga hiperativa (ginecologistas: 88,2%; urologistas: 96,7%), e os urologistas têm maior chance de solicitar esse exame (razão de chances [RC] = 3,9). Para a maioria dos entrevistados, é necessário solicitar urocultura junto com o EU. Conclusão A maioria dos ginecologistas e urologistas brasileiros que participaram deste estudo não solicita EU antes do tratamento conservador da IU, de acordo com as principais diretrizes nacionais e internacionais, e muitas vezes o solicita antes do tratamento cirúrgico da IU feminina. A indicação desse exame na abordagem inicial da bexiga hiperativa idiopática deve ser revista pelos participantes.
