Abstract
This study explores 15-year urological complications in chronic spinal cord injury (SCI) patients and investigates the predictive factors from video-urodynamic study (VUDS) and bladder management. Analyzing 864 SCI patients with a mean 15.6-year follow-up, we assessed complications and utilized multivariate logistic regression for risk evaluation. VUDS factors such as autonomic dysreflexia, detrusor sphincter dyssynergia, vesicourethral reflux (VUR), contracted bladder, and high voiding detrusor pressure significantly increased the likelihood of recurrent urinary tract infections (rUTI). Low bladder compliance, VUR, and contracted bladder notably raised the risk of hydronephrosis, while contracted bladder and detrusor overactivity with detrusor underactivity heightened chronic kidney disease risk. Volitional voiding reduced rUTI and VUR risk, whereas Valsalva maneuver-assisted voiding increased hydronephrosis risk. In conclusion, a contracted bladder identified in VUDS is associated with long-term urological complications in SCI, we propose that patients already experiencing a contracted bladder should prioritize volitional voiding as their preferred bladder management strategy to minimize the risk of additional complications such as rUTI and VUR. These findings unveil previously unexplored aspects in research, emphasizing the need for proactive management strategies in this patient population.

Duration of detrusor overactivity as an independent predictive factor of upper urinary tract deterioration in patients with traumatic spinal cord injury: results of a retrospective cohort study. Spinal Cord 2024; 62:328-335. [PMID: 38575739 DOI: 10.1038/s41393-024-00988-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 03/26/2024] [Accepted: 03/27/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE To determine whether duration of detrusor overactivity (DO) during a cystometric study is an independent predictive factor of upper urinary tract deterioration (UUTD) in patients with traumatic spinal cord injury (TSCI). STUDY DESIGN Retrospective cohort study. SETTING A rehabilitation facility in Chiang Mai, Thailand. METHODS Data were obtained from medical records of patients who underwent cystometric evaluation at 6-12 months after TSCI. The independent predictor of interest is the duration of DO, which was evaluated by the DO/cystometry ratio (DOratio). Other conventional urodynamic parameters (maximum detrusor pressure, cystometric capacity, bladder compliance, and detrusor-sphincter dyssynergia) and clinical parameters (age, sex, level and severity of injury, comorbidities, bladder emptying method, and history of urinary tract infection) were determined. The outcome was UUTD, which is indicated by chronic kidney disease (GFR < 60 ml/min/1.73 m2), hydronephrosis, and/or vesicoureteral reflux. Multivariable Cox regression analysis was used to determine the independent associations between DOratio and UUTD by adjusting with all other parameters. RESULTS Medical records of 194 patients with TSCI were included in the study. During a combined total of 1260 follow-up years of those patients, 34 UUTD events were identified, indicating an incidence rate of 27.0 cases per 1000 person-years. After adjusting for all other parameters, a high DOratio (≥0.33) was significantly associated with UUTD (hazard ratio = 3.00 [95% CI: 1.12-7.99], p = 0.025). CONCLUSION DOratio may be an independent cystometric predictor of UUTD in patients with TSCI. However, further prospective study is needed prior to applying DOratio as a predictor of UUTD in clinical settings. CLINICAL TRIAL REGISTRATION There was no clinical trial registration since this study is not a clinical trial.

Clinical characteristics and molecular mechanisms underlying bladder cancer in individuals with spinal cord injury: a systematic review. BMC Urol 2024; 24:111. [PMID: 38778291 PMCID: PMC11110351 DOI: 10.1186/s12894-024-01457-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 03/15/2024] [Indexed: 05/25/2024] Open
Abstract
BACKGROUND Patients with spinal cord injury have a relatively high risk for bladder cancer and often complicated with bladder cancer in advanced stages, and the degree of aggressiveness of malignancy is high. Most of the literature is based on disease clinical features while, our study reviews the clinical characteristics and molecular mechanisms of spinal cord injury patients with bladder cancer, so that it might help clinicians better recognize and manage these patients. METHOD We searched PubMed, Web of Science and Embase, using retrieval type like ("Neurogenic Lower Urinary Tract Dysfunction" OR "Spinal cord injury" OR "Spinal Cord Trauma") AND ("bladder cancer" OR "bladder neoplasm" OR "bladder carcinoma" OR "Urinary Bladder Neoplasms" OR "Bladder Tumor"). In Web of Science, the retrieval type was searched as "Topic", and in PubMed and Embase, as "All Field". The methodological quality of eligible studies and their risk of bias were assessed using the Newcastle-Ottawa scale. This article is registered in PROSPERO with the CBD number: CRD42024508514. RESULT In WOS, we searched 219 related papers, in PubMed, 122 and in Embase, 363. Thus, a total of 254 articles were included after passing the screening, within a time range between 1960 and 2023. A comprehensive analysis of the data showed that the mortality and incidence rates of bladder cancer in spinal cord injury patients were higher than that of the general population, and the most frequent pathological type was squamous cell carcinoma. In parallel to long-term urinary tract infection and indwelling catheterization, the role of molecules such as NO, MiR 1949 and Rb 1. was found to be crucial pathogenetically. CONCLUSION This review highlights the risk of bladder cancer in SCI patients, comprehensively addressing the clinical characteristics and related molecular mechanisms. However, given that there are few studies on the molecular mechanisms of bladder cancer in spinal cord injury, further research is needed to expand the understanding of the disease.

Int Urol Nephrol 2024; 56:1205-1216.

Abstract
The main problems of neurogenic lower urinary tract dysfunction (NLUTD) in patients with spinal cord injury (SCI) consist of impaired urine storage, impaired bladder emptying, or both. The priorities in the management of SCI-NLUTD should be preservation of renal function, followed by freedom from urinary tract infections and improvement of quality of life. Management of NLUTD in patients with SCI must be based on urodynamic findings rather than clinical evaluations. In the hospital without urodynamic equipment, careful measurement of intravesical pressure and safety functional bladder capacity in conjunction with clinical assessment are also feasible. Identification of high-risk patients is important for preventing urological complications in patients with chronic SCI. The management of NLUTD should start with conservative bladder management and medical treatment. Patients with SCI should be regularly followed up, and any NLUTDs and urological complications should be adequately treated. When surgical intervention is necessary, less invasive and reversible procedures should be considered first, and any unnecessary surgery should be avoided. This article reports the current evidence and expert opinions on the patient-centered bladder management of NLUTD in chronic SCI patients in Taiwan. To avoid renal function deterioration and urological complications, annual active surveillance of bladder and renal function is mandatory, especially for high-risk SCI patients.

Abstract
STUDY DESIGN Qualitative descriptive. OBJECTIVES To describe the experiences of people with Spinal Cord Injury (SCI) re-admitted to the hospital due to continence-related complications. SETTING Inpatient service of a large spinal unit in North-West of Italy. METHODS Semi-structured interviews were conducted on a purposive sample of people with SCI (n = 11; age range 22-66 years, n = 5 females, n = 6 with cervical injuries), audio-recorded, and transcribed verbatim (duration range 38-52 min). Data were analysed inductively using the thematic analysis approach as described by Braun and Clarke. RESULTS Three main themes were identified: (i) managing the frustration of continence-related complications; (ii) finding your way to deal with continence-related complications; (iii) identifying precise needs to deal with continence-related complications. Obtained findings highlighted the perceived emotional and physical burden suffered by people with SCI and their caregivers regarding the constant look for solutions and renounces to social participation, the different strategies implemented to address continence-related complications, and the unmet or partially met needs of people with SCI regarding support in transition to the community, infrastructure, and reliable information or education. CONCLUSIONS Continence-related complications have a significant impact on the lives of people with SCI and their families. Interventions using technological tools and peer participation could reduce the burden associated with continence-related complications. Specific instruments are needed to facilitate evaluation, goal setting, and promote discussion of continence to allow HCPs to support people with SCI. Structured follow-up for SCI survivors should also focus on their needs to improve knowledge, facilitate decision making, and promote preventive behaviours.

Abstract
Objectives To investigate the occurrence rate of urinary tract infections (UTIs) in the early phase after performing intermittent catheterization (IC) and to explore the possible factors associated with UTIs after performing IC among people with spinal cord injury (SCI). Setting An inpatient rehabilitation department of a teaching hospital in China. Design Retrospective chart review. Methods A retrospective chart review was carried out for traumatic and non-traumatic SCI patients after performing IC during their inpatient stay. Demographic information, comorbidity of diabetes, urine analysis results before IC, method of IC (sterile or clean), use of bladder irrigation, cessation of IC and its reasons, and UTI events were collected. Results A total of 183 adult individuals were included, of which 60 (32.8%) of them were women. The median age was 49.0 years. The median time post-injury was 2 months. The overall occurrence rate of UTI after performing IC was 1.31 (95% confidence intervals: 0.96-1.77) events per 100 days. Sixty-nine (37.7%) patients discontinued IC during hospitalization, and UTIs were the leading reason for cessation (50.7%). Female sex, use of antibiotics for infections other than UTI, and use of bladder irrigation were found to be associated with a lower occurrence rate of UTI in the early phase after performing IC, with an odds ratio of 0.38 (p = 0.019), 0.20 (p = 0.022), and 0.24 (p < 0.001), respectively. Conclusion UTI after performing IC is prevalent among people with SCI. The study indicated that antibiotic prophylaxis and routine bladder irrigation might be associated with the reduction in UTI in the early phase after performing IC. Further research is needed to provide more evidence.

Abstract
Urinary tract infections (UTIs) are among the most common bacterial infections seen in clinical practice. The ascent of UTI-causing pathogens to the kidneys results in pyelonephritis, which can trigger kidney injury, scarring and ultimately impair kidney function. Despite sizable efforts to understand how infections develop or are cleared in the bladder, our appreciation of the mechanisms by which infections develop, progress or are eradicated in the kidney is limited. The identification of virulence factors that are produced by uropathogenic Escherichia coli to promote pyelonephritis have begun to fill this knowledge gap, as have insights into the mechanisms by which kidney tubular epithelial cells oppose uropathogenic E. coli infection to prevent or eradicate UTIs. Emerging data also illustrate how specific cellular immune responses eradicate infection whereas other immune cell populations promote kidney injury. Insights into the mechanisms by which uropathogenic E. coli circumvent host immune defences or antibiotic therapy to cause pyelonephritis is paramount to the development of new prevention and treatment strategies to mitigate pyelonephritis and its associated complications.

Abstract
Given the increase in life expectancy, aging with a pre-existing spinal cord injury (SCI) is becoming more common. This condition is challenging as compromised health status and functional independence can worsen. We aimed to provide an updated overview of the consequences of aging with SCI, highlighting the main challenges facing this population in a narrative review of the current literature we retrieved from the PubMed database from 2000 to 2022 on any aspect related to aging in persons with SCI. Here we address adverse circumstances that increase disability and hinder an active lifestyle, such as progressive physical deterioration, secondary health conditions, limitations in personal activity, changes in family and social support structures, aging of caregivers, and depletion of economic resources. Favorable changes are also observed, including psychosocial adjustments that improve quality of life. Additionally, various interventions are discussed to promote well-being, health, and social participation. Due to the relevance of this issue, people with SCI and all those who take care of them must have up-to-date information to carry out the necessary measures to promote healthy aging in a more inclusive social environment.
