Abstract
INTRODUCTION If the use of intermittent catheterization has revolutionized the prognosis of neuro-urology patients, it seems necessary to question the ecological cost of single-use catheters, in a process of decarbonization of the health sector. The aim of this work is to identify the environmental impact of intermittent catheterization and potential solutions to reduce it. METHODS A review of the literature on the environmental impact of intermittent catheterizations was conducted. Potential solutions to reduce this impact and possible alternatives were then studied based on data from the literature. RESULTS Only two studies were identified. The first estimated the amount of waste generated by intermittent catheterization in the USA to be between 4400 and 38,964 tons per year. The second study showed a higher overall environmental impact of thermoplastic polyurethane (TPU) catheters than polyvinyl chloride (PVC) catheters and catheters made from polyolefin material. Reuse of catheters would reduce the amount of waste, but the paucity of data does not allow us to determine if the incidence of urinary tract infection would be affected. Alternative micturition methods, in addition to the complications they may cause, require the use of collection bags or pads, which also have an environmental impact. Other treatments for dysuria exist, but the evidence is limited and does not cover all patient populations. CONCLUSION With limited alternatives, it appears essential to develop more environmentally friendly catheters.

A Study of DNA Methylation of Bladder Cancer Biomarkers in the Urine of Patients with Neurogenic Lower Urinary Tract Dysfunction. BIOLOGY 2023; 12:1126. [PMID: 37627010 PMCID: PMC10452268 DOI: 10.3390/biology12081126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 08/03/2023] [Accepted: 08/09/2023] [Indexed: 08/27/2023]
Abstract
Background: Bladder cancer (BCa) in patients suffering from neurogenic lower urinary tract dysfunction (NLUTD) is a significant concern due to its advanced stage at diagnosis and high mortality rate. Currently, there is a scarcity of specific guidelines for BCa screening in these patients. The development of urine biomarkers for BCa seems to be an attractive non-invasive method of screening or risk stratification in this patient population. DNA methylation is an epigenetic modification, resulting in the transcriptional silencing of tumor suppression genes, that is frequently detected in the urine of BCa patients. Objectives: We aimed to investigate DNA hypermethylation in five gene promoters, previously associated with BCa, in the urine of NLUTD patients, and in comparison with healthy controls. Design, setting and participants: This was a prospective case-control study that recruited neurourology outpatients from a public teaching hospital who had suffered from NLUTD for at least 5 years. They all underwent cystoscopy combined with biopsy for BCa screening following written informed consent. DNA was extracted and DNA methylation was assessed for the RASSF1, RARβ, DAPK, TERT and APC gene promoters via quantitative methylation-specific PCR in urine specimens from the patients and controls. Results: Forty-one patients of mixed NLUTD etiology and 35 controls were enrolled. DNA was detected in 36 patients' urine specimens and in those of 22 controls. In the urine specimens, DNA was hypermethylated in at least one of five gene promoters in 17/36 patients and in 3/22 controls (47.22% vs. 13.64%, respectively, p = 0.009). RASSF1 was hypermethylated in 10/17 (58.82%) specimens with detected methylation, APC in 7/17 (41.18%), DAPK in 4/17 (23.53%), RAR-β2 in 3/17 (17.56%) and TERT in none. According to a multivariate logistic regression analysis, NLUTD and male gender were significantly associated with hypermethylation (OR = 7.43, p = 0.007 and OR = 4.21; p = 0.04, respectively). In the tissue specimens, histology revealed TaLG BCa in two patients and urothelial squamous metaplasia in five patients. Chronic bladder inflammation was present in 35/41 bladder biopsies. Conclusions: DNA hypermethylation in a panel of five BCa-associated genes in the urine was significantly more frequent in NLUTD patients than in the controls. Our results warrant further evaluation in longitudinal studies assessing the clinical implications and possible associations between DNA hypermethylation, chronic inflammation and BCa in the NLUTD population.

Abstract
Background Urinary bladder cancer is the eighth-most frequent carcinoma in men, commonly occurs in elderly male. Major risk factors are smoking, chronic cystitis, urinary stones. The most common histologic variant of bladder cancer is urothelial carcinoma (UC), but certain variants are unusual yet aggressive for which there is no consensus guideline of therapy. Those entities include neuroendocrine tumors both primary and metastatic, squamous cell carcinoma, and sarcomatoid carcinoma. Neuroendocrine tumors comprise carcinoid, small-cell carcinoma, and large-cell carcinoma. Aim The present study is undertaken to highlight certain biological features of these unusual aggressive histological forms of bladder carcinoma and their recent treatment modality to prevent recurrence, metastasis, upgrading of tumor stage, and enable surprisingly complete remission. Methods This piece of hospital-based perspective study was done from June 2018 to May 2020. Both transurethral resection of bladder tumor and cystectomy surgical samples of the symptomatic patients were collected from the urology department of our institute along with demographic data. Then processed, stained in both routine H and E stain and immunohistochemical stains (Immunohistochemistry [IHC]) like PanCK, NSE, synaptophysin, chromogranin, etc. Results Total number of bladder cancer encountered was 42 cases; of these five rare variants were observed, i.e., one case each of primary and secondary small cell neuroendocrine carcinoma, one large cell carcinoma, one squamous cell carcinoma (SCC), and one case of sarcomatoid carcinoma. Histomorphology with IHC conferred the diagnosis then multimodality therapy (neoadjuvant/radiotherapy/surgery) was installed and followed up. Conclusion The unconventional forms of UC can be easily diagnosed by histomorphology and can have better survival with the help of the recent multimodal treatment approach.

Bladder cancer detection in patients with neurogenic bladder: are cystoscopy and cytology effective, and are biomarkers pertinent as future diagnostic tools? A scoping review. World J Urol 2022; 40:1897-1913.

Abstract
PURPOSE To summarize the current state of knowledge on bladder cancer diagnosis and screening in neurogenic bladder patients, and to explore the potential contribution of biomarkers in this context. METHODS A scoping review was performed to retrieve cystoscopy and urinary cytology performance for bladder cancer detection in neurogenic bladder patients. We also retrieved information of certified urinary biomarkers in bladder cancer detection and their potential application for this specific population. RESULTS A total of 1092 articles were identified; 19 of them were included in the scoping review regarding cytology and cystoscopy performance in patients with neurogenic bladder and 33 were included as related to biomarkers in bladder cancer. No significant study stood out to recommend bladder cancer screening in this specific population using cytology and cystoscopy because of the scarcity of results, low level-of-evidence studies, and lack of studies specifically designed to assess the test performance in this population. Two biomarkers were retained as potential future diagnostic tools: FISH analysis to detect chromosomal changes, and PCR for TERT and FGFR3 promoter mutation detection, associated or not with KRAS mutation detection. CONCLUSION There is no sufficient quality data to support cystoscopy and urinary cytology as effective tools for the diagnostic and surveillance of bladder cancer in neurogenic bladder patients. FISH analysis to detect chromosomal changes, and PCR for TERT and FGFR3 promoter mutation detection, associated or not with KRAS mutation detection, stand out as candidates of interest for bladder cancer detection in this specific population and should be prospectively tested.

Abstract
Small-scale studies indicate that spinal cord injury (SCI) may lead to significant gastrointestinal and bladder dysfunction. However, how the prevalence of chronic disease related to these dysfunctions compares with non-SCI individuals and whether there are robust relationships to level and severity of injury are still unclear. Here, our goal was to provide high-level evidence on the association between bladder and gastrointestinal dysfunction and SCI using population-level data from the Canadian Community Health Survey (CCHS) and the SCI Community Survey. Data from more than 60,000 individuals in the 2010 CCHS and 1500 individuals with SCI from the SCI Community Survey were analyzed. We used bi-variable and multi-variable logistic regression to examine relationships between explanatory and outcome variables. We found that SCI was associated with increased odds of urinary incontinence (adjusted odds ratio [aOR] = 5.0, 95% confidence interval [CI]: 3.4-7.1), bowel disorders (aOR = 2.3, CI: 1.5-3.4), as well as gastric ulcers (aOR: 3.3, CI: 2.1-4.8), even after adjusting for key confounding variables. Additionally, we found that complete SCI was associated with increased odds of urinary tract infections (aOR = 2.0, CI: 1.6-2.5) and bowel incontinence (aOR = 2.1, CI: 1.7-2.6). Individuals with SCI are at increased odds for having bladder and gastrointestinal dysfunction, certain aspects of which are dependent on the level and severity of injury. Targeted intervention and prevention strategies to manage bladder and bowel problems after SCI should be a priority for both caregivers and policy makers.

Abstract
PURPOSE Neurogenic bladder due to spinal cord injury has significant consequences for patients' health and quality of life. Regular surveillance is required to assess the status of the upper and lower urinary lower urinary tracts and prevent their deterioration. In this review, we examine surveillance techniques in neurogenic bladder, describe common complications of this disease, and address strategies for their management. METHODS This work represents the efforts of SIU-ICUD joint consultation on Urologic Management of the Spinal Cord injury. For this specific topic, a workgroup was formed and comprehensive literature search of English language manuscripts regarding neurogenic bladder management was performed using key words of neurogenic bladder. Articles were compiled, and recommendations in the chapter are based on group discussion and follow the Oxford Centre for Evidence-based Medicine system for Levels of Evidence (LOEs) and Grades of Recommendation (GORs). RESULTS At a minimum, patients should undergo an annual history and physical examination, renal functional testing (e.g., serum creatinine), and upper tract imaging (e.g., renal ultrasonography). The existing evidence does not support the use of other modalities, such as cystoscopy or urodynamics, for routine surveillance. Urologic complications in neurogenic bladder patients are common and often more complex than in the general population. CONCLUSIONS There is a shortage of high-quality evidence to support any particular neurogenic bladder surveillance protocol. However, there is consensus regarding certain aspects of regular genitourinary system evaluation in these patients. Proper surveillance allows the clinician to avoid or address common urological complications, and to guide, alter, or maintain appropriate therapeutic regimens for individual patients.

Abstract
Patients with long-term suprapubic cystostomy can rarely develop squamous cell carcinoma (SCC) of the suprapubic cystostomy tract. In addition to the few reported cases in the literature, this paper reports a case of suprapubic cystostomy SCC in an 88-year-old man without bladder involvement. Vigilance about any abnormal lesion at the site of suprapubic cystostomy is important among health providers and patients for early detection of SCC.

Abstract
AIM To perform a systematic review of the literature regarding epidemiology, diagnosis, management and prognosis of bladder cancer in the neuro-urological patient population, in order to serve as a basis for future recommendations and research. METHODS A systematic review was performed according to the PRISMA-Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Statement. Embase was searched for studies providing data on epidemiology, diagnosis, management and prognosis of bladder cancer in neuro-urological patients. RESULTS After screening 637 abstracts, 15 studies (13 retrospective and 2 prospective studies) were included in this study. We identified 332 patients (0.3%) who were diagnosed with bladder cancer. This mostly affected mostly men (59.3%) and spinal cord injured patients (98.8%). Mean age at diagnosis was 56.1 years. Bladder cancer occurred after a long period of evolution of the neurological disease (24.9 years). Gross hematuria was the predominating presenting symptom (31.6% of cases). Indwelling urethral or supra-pubic catheters were used in 44.5% of patients. The most frequent histological subtype of bladder cancer was transitional cell carcinoma (53.1%), followed by squamous cell carcinoma (33.5%). Muscle-invasive bladder cancer was reported in 67.7% of patients. The mean cancer-specific mortality rate was of 47.1%. CONCLUSIONS The prevalence and high mortality rate of bladder cancer in neuro-urological patients underlines the importance of long-term follow-up in this specific population. This highlights the necessity of further studies in this field.

Abstract
INTRODUCTION Life expectancy for people with spinal cord injury has shown a marked increase due to modern advances in treatment methods and in neuro-urology. However, since life expectancy of people with paralysis increases, the risk of developing of urinary bladder cancer is gaining importance. MATERIALS AND METHODS Single-centre retrospective evaluation of patient data with spinal cord injuries and proven urinary bladder cancer and summary of the literature. RESULTS Between 1998 and 2014, 24 (3 female, 21 male) out of a total of 6599 patients with spinal cord injury were diagnosed with bladder cancer. The average age at bladder cancer diagnosis was 57.67 years, which is well below the average for bladder cancer cases in the general population (male: 73, female: 77). All but one patient had a latency period between the onset of the spinal paralysis and tumour diagnosis of more than 10 years. The median latency was 29.83 years. The median survival for these patients was 11.5 months. Of the 24 patients, 19 (79%) had muscle invasive bladder cancer at ≥T2 at the time of diagnosis. The type of neurogenic bladder (neurogenic detrusor overactivity or acontractility) and the form of bladder drainage do not appear to influence the risk. Long-term indwelling catheter drainage played only a minor role in the investigated patients. CONCLUSIONS The significantly younger age at onset and the frequency of invasive tumours at diagnosis indicate that spinal cord injury influences bladder cancer risk and prognosis as well. Early detection of bladder cancer in patients with spinal cord injury remains a challenge.

Abstract
OBJECTIVES To conduct a scoping review of all the literature related to bladder cancer in individuals with spinal cord injuries (SCIs). METHODS We searched for trials in MEDLINE, EMBASE, CINAHL and the Cochrane Register. Meta-analysis methods were used to evaluate these studies. RESULTS A total of 18 articles were identified and included as the evidence base for analysis. The incidence of bladder cancer in individuals with SCI is 6‰ (95% confidence interval (CI), 5-6‰, I2=49.2%). Mean patient age at bladder cancer diagnosis was 50 years (95% CI, 45-55 years, I2=92.7%). Length of indwelling catheterization of the patient population ranged from 6 to 29 years, with an average of 16 years (95% CI, 12-20 years, I2=94.4%). The interval between SCI and the first diagnosis of bladder cancer was 24 years (95% CI, 21-27 years, I2=85.3%). In the SCI population the estimated percent of squamous cell carcinoma is 36.8% (95% CI, 31.6-42.5%, I2=32.3%). In addition, 46.3% (95% CI, 33.7-59.4%, I2=40.5%) of the bladder cancer histology was traditional transitional cell carcinoma. Other pathological subtypes account for 17.1% (95% CI, 12.8-22.6%, I2=21.5%). The 1-year overall survival rate after treatment of bladder cancer was 62.1% (95% CI, 56.2-66.7%, I2=21.3%). Cystoscopy demonstrated a sensitivity of 64% (95% CI, 49.3-76.5%, I2=37.7%) for detecting bladder cancer. Cytology demonstrated a sensitivity of 36.3% (95% CI, 21.5-54.3%, I2=40.2%) for detecting bladder cancer. CONCLUSION Bladder cancer is a rare and potentially lethal occurrence in SCI patients. Physicians need to have a high index of suspicion for bladder cancer, particularly among SCI patients managed with long-term indwelling catheters.

Abstract
OBJECTIVE To highlight the current understanding of the epidemiology, clinicopathological characteristics, and management of squamous cell carcinoma (SCC) of the bladder, as it accounts for 2-5% of bladder tumours, with a focus on non-bilharzial-associated SCC (NB-SCC). The standard treatment for bladder SCC remains radical cystectomy (RC). We present an updated clinical profile of bladder SCC and a review of NB-SCC therapeutic approaches, including RC, neoadjuvant and adjuvant treatments, radiotherapy, chemotherapy, and immunotherapy. METHODS Using search terms relating to SCC, urinary bladder, and treatment modalities, we performed a search of the PubMed and Embase databases to identify NB-SCC treatment approaches and outcomes. Peer-reviewed English language reports from 1975 to present assessing SCC management were included. Two authors independently screened and extracted the data. RESULTS Of the 806 articles screened, 10 met the pre-defined inclusion criteria. RC was performed in seven of the 10 studies. Although radiotherapy alone yielded poor outcomes, preoperative radiotherapy and RC were associated with improved survival. There is little evidence supporting the use of chemotherapy in NB-SCC, and its efficacy in relation to RC is not known. CONCLUSION Based on current literature, there is insufficient evidence to provide a treatment recommendation for NB-SCC. Whilst RC is the standard of care, the role of preoperative radiotherapy should be revisited and compared to RC alone. Additional studies incorporating multimodal approaches, contemporary radiation techniques, and systemic therapies are warranted. Immunotherapy as a treatment for bladder SCC has yet to be investigated.

Abstract
Anticholinergics and intermittent catheterization are the cornerstones of bladder management in early multiple sclerosis (MS). In advanced MS however, bladder management is based more on tradition than on evidence. Nurses seem to deal with catheter problems and chronic incontinence. Despite the abundant use of indwelling catheters, there is a lack for guidelines on catheter-induced problems. The psychosexual and social impact of bladder problems in advanced MS is often neglected. The international multidisciplinary special interest group on sexual, urological and bowel dysfunction in MS (SUBDIMS) as a special interest group of the Rehabilitation in Multiple Sclerosis (RIMS) was confronted with a high variability in practice and a lack of guidelines. A literature review was prepared during three multidisciplinary expert meetings. This review will be the basis of further initiatives to improve the urological treatment of patients with advanced MS.

Abstract
Squamous cell carcinoma arising from a urinary stoma is exceedingly rare, and none so far is reported from a cutaneous ureterovesical stoma. Squamous cell carcinoma usually occurs as a late complication of urinary diversion, and we report the first such case in a cutaneous ureterovesical stoma with a review of published literature.

Abstract
Bladder tumor arising in a spina bifida patient is rare and may be clinically latent. We report the case of a 61-year-old female patient with spina bifida, neurogenic bladder, and a history of recurrent urinary tract infections. A B-ultrasound and non-contrast computed tomography scan did not reveal any bladder mass, but an unexplained "well-filled" bladder was observed, which was confusing as the catheter was present and open. However, a subsequent cystoscopic evaluation revealed a large bladder mass measuring 9.5 × 9.0 × 6.5 cm³, which almost filled the entire bladder. The mass had coarse and flocculent surface and seemed to be free from each observed wall of the urinary bladder. It was diagnosed as an infectious necrotic mass based on its appearance. During transurethral resection of the mass, a bladder tumor was suspected as small blood vessels and bleeding appeared within the inner layer of the mass. Pathological examination revealed necrotic material, inflammatory cells, and urothelial carcinoma cells. Then, a radical cystectomy was performed, and the pathological results indicated stage pT3bN0M0 transitional cell carcinoma. In the gross specimen, the base of the tumor measured 3 × 3 cm² on the top of the back wall of the bladder. Bladder tumors may have atypical presentations in patients with spina bifida. Regular screening is helpful for earlier detection and improving outcomes of bladder tumors in such patients.

Abstract
Chronic indwelling urinary catheters (CIDCs) are known as a risk factor for bladder cancer in patients with spinal cord injury (SCI). This study examined the potential risk of bladder cancer from CIDCs in patients without SCI.The National Health Insurance Research Database in Taiwan was used to identify SCI patients (N = 1816). This group was compared against a control CIDC cohort without SCI (N = 1816) and a reference cohort with normal individuals without SCI and a record of CIDC (N = 7264). Comparisons were made based on age and gender matching over a maximum of 11 follow-up years. The incidence risk and hazard ratio (HR) of bladder cancer were estimated in all 3 groups.During the follow-up period, the bladder cancer incidence rates were 68.90 and 102.53 per 100,000 person-years in the SCI and CIDC-non-SCI groups, respectively. These values were both higher than that of the reference cohort (12.00 per 100,000 person-years). Patients who had history of SCI (HR: 6.51; 95% CI, 2.56-16.52) or CIDC without SCI (HR: 9.11; 95% CI, 3.9-21.29) had a higher risk of bladder cancer compared with the reference cohort.Patients with CIDCs may have an increased risk of bladder cancer development, especially in older aged and male patients compared with general population.

Abstract
The costs of spinal cord injury and its complications are high in personal, social and financial terms. Complications include bladder cancer, for which the risk is 16-28 times higher than that of the general population, There is currently little consensus regarding the cause of this discrepancy. As microRNAs are stable biomarkers and potential therapeutic targets of cancer, the present study aimed to explore the underlying mechanisms of this phenomenon by examining changes in the microRNAome. Rats were used to produce models of spinal cord injury. Microarrays and bioinformatics were used to investigate the cancer-associated microRNAs that are upregulated in rat bladders following spinal cord injury. In order to validate the results, quantitative reverse transcription-polymerase chain reaction (qRT-PCR), western blotting and immunohistochemistry were performed. The expression of miR-1949 was found to be deregulated and abundant in the rat bladder following spinal cord injury. Bioinformatics demonstrated that retinoblastoma 1, which is involved in tumorigenesis, is a target gene of miR-1949. qRT-PCR, western blotting and immunohistochemistry confirmed the results of the microarray analysis. In addition, it was shown that miR-1949 expression was not influenced by aging. Furthermore, the expression of miR-1949 was stable until the third month following spinal cord injury, after which it significantly increased. If this increase was prolonged, the expression of retinoblastoma 1 may decline to a carcinogenic level. The present study suggests a role for miR-1949 in the translational regulation of retinoblastoma 1 and in subsequent bladder tumorigenesis following spinal cord injury.

Abstract
Squamous cell carcinoma (SCC) of the bladder is uncommon, but can arise in the setting of long-term bladder catheterization and chronic inflammation. SCC can arise primarily from the suprapubic catheter tract, but fewer than 10 such cases have been reported. We document 2 cases of SCC arising from the suprapubic tract associated with chronic indwelling urinary catheters. SCC must be differentiated from granulomatous conditions, which are quite common in patients with suprapubic catheters.

Abstract
INTRODUCTION Over recent years the button vesicostomy has become an alternative management option in children with poor bladder emptying, when clean intermittent catheterisation (CIC) cannot be initiated for reasons of age, sensation, or urethral anatomy. This study reviews recent experience of this technique and evaluates its use. METHODS Retrospective review of patients who had a button vesicostomy to permit bladder drainage between 1998 and 2011. RESULTS Thirty children underwent button vesicostomy insertion aged between 4 days and 16 years. Indications were neuropathic bladders (n = 15), congenital hypotonic bladders (n = 6), functional bladder disorders (n = 5), and post-obstruction bladders (n = 4). The median length of use was 11 months; however, 7 patients still have the button in situ. Minor complications (n = 12) included transient leakage, wound infection, and overgranulation. Major complications included 2 UTIs, 1 device failure, and 2 significant leaks, requiring revision of the tract and removal of the button. CONCLUSION The button vesicostomy is a suitable and safe technique for use in the short- and medium-term. The procedure has minimal morbidity and therefore is acceptable to families. It has a wide scope, including patients with a neuropathic bladder as an alternative to CIC and where temporary drainage is required until bladder function can recover.

Abstract
OBJECTIVE To evaluate the risk of prostate and bladder cancers in patients with spinal cord injury (SCI). MATERIALS AND METHODS We used data obtained from the National Health Insurance system of Taiwan for this study. The SCI cohort contained 54,401 patients with SCI, and each patient was randomly frequency matched with 4 people from the general population (without SCI) based on age, sex, and index date. Incidence rates, SCI cohort to non-SCI cohort rate ratios, and hazard ratios were measured to evaluate the cancer risks. RESULTS Patients with SCI showed a significantly lower risk of developing prostate cancer compared with subjects without SCI (adjusted hazard ratio = 0.73; 95% confidence interval = 0.59, 0.90), after accounting for the competing risk of death. No significant difference in the risk of bladder cancer emerged between the SCI and control groups. Further analyses found a higher spinal level of SCI tended to predict a lower risk for prostate cancer. CONCLUSIONS Patients with SCI incurred a lower risk for prostate cancer compared with people without SCI. The risk for bladder cancer did not differ between people with or without SCI.

Abstract
AIMS Choosing the appropriate bladder management strategy for the spinal cord injury patient with neurogenic bladder and hand function prohibitive of self catheterization (urethral or stomal) catheterization is complex and based on limited literature. We have catalogued the available data in this review. METHODS A literature review was conducted on external sphincterotomy, suprapubic tube, ileal conduit, and ileovesicostomy between 1994 and 2012. Articles on neurogenic bladder focused primarily on spinal cord injury were included. Important aspects of each technique, patient selection, urologic events, and quality of life are described. CONCLUSION The available literature consists primarily of level 3 data. Patient reported outcomes were rarely measured. External sphincterotomy is a good option for males who are candidates for an external catheter and who wish to avoid a complicated reconstruction-most will need re-operations for failure. Suprapubic tube is an option in both genders. Complaints usually involve urine leakage and urinary tract infection, which typically resolve with conservative measures. There is some evidence to support patient satisfaction. Ileal conduit is an option for all patients with quadriplegia, offering continuous drainage and absence of foreign material. Many providers and patients will choose more conservative options first. The ileovesicostomy is best applied to small bladders with severe overactivity. The "reversibility" of this procedure makes it attractive to those not interested in an ileal conduit and who have had complications from prolonged suprapubic tube placement. The authors conclude with recommendations for future research, most importantly more standard reporting of objective data.

Abstract
Herein we report a case of a squamous cell carcinoma of a well-healed suprapubic cystostomy tract scar involving the bladder mucosa in a 56-year-old man. He presented with a spontaneous suprapubic urinary leak from a suprapubic cystostomy tract scar. He had a history of urethral stricture and failed urethroplasty. Preoperative cystoscopy suggested a bladder mass. Transurethral biopsy of the bladder mass revealed a squamous cell carcinoma confined to the suprapubic cystostomy tract involving the bladder mucosa. The patient died 6 months after the start of radiation therapy after lung metastasis and pneumonia.

Abstract
The patient was a 38-year-old man. A cystostomy catheter had been inserted when he was 23 years of age for neuropathic bladder due to cervical spinal cord injury at 20 years of age. Purulent discharge from around the cystotomy had continued for approximately 4 months. Examination revealed the formation of a subcutaneous tumor around the cystostomy, with elevated carcinoembryonic antigen (CEA) levels (459.4 ng/ml) in the blood. Urothelial carcinoma was detected using open biopsy. It was considered that primary urothelial carcinoma of the bladder had progressed along the cystostomy, and clinical stage 4 cT4N2M0 was diagnosed, with intrapelvic lymph node metastasis evident on imaging. Four courses of gemcitabine-cisplatin chemotherapy were administered; a partial response was obtained, after which cystectomy and ileal conduit formation were performed with the main aim of improving difficulty in urination. However, retroperitoneal lymph node and liver metastases were observed 1 month postoperation with rapid enlargement; the patient died approximately 2 months after the surgery. The CEA level was observed to be 18,998 ng/ml before he died. Here, we have reported this case with a discussion of the literature concerning the association between long-term indwelling catheter in patients with spinal cord injury and the development of bladder cancer.

Bladder cancer in individuals with spinal cord injuries. Spinal Cord 2013; 51:516-21.

Abstract
STUDY DESIGN Prospective scoping review. OBJECTIVES To conduct a scoping review of all the literature related to bladder cancer in individuals with spinal cord injuries (SCI). METHODS Literature search of the databases Pubmed, CINAHL, ProQuest, PsychINFO and Scopus up to and including August 2012. Articles related to bladder cancer among SCI patients were identified, and data pertaining to epidemiology, risk factors, screening, prevention and management was reviewed and summarized. RESULTS An association between bladder cancer and SCI was first reported in the 1960s, with some case reports suggesting an alarmingly high rate among SCI patients. More recent epidemiological studies have reported this risk to be substantially lower. However, bladder cancer in SCI patients tends to present at an earlier age and at a more advanced pathological stage than bladder cancer in the general population. Presenting symptoms may be atypical, and early recognition is important to improve prognosis with surgical resection. Several risk factors have been identified, including indwelling catheters, urinary tract infections and bladder calculi. Screening of SCI patients for bladder cancer is routinely recommended in many SCI management guidelines and by expert consensus; however, evidence for screening tools and protocols is lacking. CONCLUSION Bladder cancer is a rare, and potentially lethal occurrence in SCI patients. Physicians need to have a high index of suspicion for bladder cancer, particularly among SCI patients managed with long-term indwelling catheters.

Abstract
Urinary catheterization elicits major histological and immunological changes that render the bladder susceptible to microbial invasion, colonization, and dissemination. However, it is not understood how catheters induce these changes, how these changes act to promote infection, or whether they may have any protective benefit. In the present study, we examined how catheter-associated inflammation impacts infection by Enterococcus faecalis, a leading cause of catheter-associated urinary tract infection (CAUTI), a source of significant societal and clinical challenges. Using a recently optimized murine model of foreign body-associated UTI, we found that the implanted catheter itself was the primary inducer of inflammation. In the absence of the silicone tubing implant, E. faecalis induced only minimal inflammation and was rapidly cleared from the bladder. The catheter-induced inflammation was only minimally altered by subsequent enterococcal infection and was not suppressed by inhibitors of the neurogenic pathway and only partially by dexamethasone. Despite the robust inflammatory response induced by urinary implantation, E. faecalis produced biofilm and high bladder titers in these animals. Induction of inflammation in the absence of an implanted catheter failed to promote infection, suggesting that the presence of the catheter itself is essential for E. faecalis persistence in the bladder. Immunosuppression prior to urinary catheterization enhanced E. faecalis colonization, suggesting that implant-mediated inflammation contributes to the control of enterococcal infection. Thus, this study underscores the need for novel strategies against CAUTIs that seek to reduce the deleterious effects of implant-mediated inflammation on bladder homeostasis while maintaining an active immune response that effectively limits bacterial invaders.

Abstract
PURPOSE There is no consensus on the appropriate urological followup of individuals after spinal cord injury but it is well known that they are at risk for renal deterioration, bladder cancer and stones. We systematically reviewed the literature to evaluate evidence of urological screening in this population. MATERIALS AND METHODS We reviewed 385 abstracts, of which 50 met study inclusion criteria. We rated evidence using American Academy of Neurology 2004 guidelines. RESULTS A total of 12 articles evaluated urinary tract infection screening. Patient reported symptoms used to predict urinary tract infection yielded mixed results and urine dipstick testing had the same accuracy as microscopy. Routine urine culture was unnecessary in healthy, asymptomatic individuals with normal urinalysis. Urodynamics probably must be done periodically (6 articles) but there was no information on frequency. In 11 articles ultrasound was recommended as a useful, noninvasive and possibly cost-effective screening method. Renal scan was a good method for further testing, especially if ultrasound was positive (11 articles). Evidence was sufficient (11 articles) to recommend ultrasound of the urinary tract to detect urinary tract stones with good sensitivity but not plain x-ray of the kidneys, ureters and bladder (2 articles). There was insufficient evidence to recommend urine markers or cytology for bladder cancer screening (9 articles). CONCLUSIONS Based on this review no definitive recommendations for screening can be made except routine renal ultrasound. Urodynamics are an important part of screening but the frequency is unclear. The optimum bladder cancer screening method has not been defined.

Abstract
BACKGROUND Patients with spinal cord injury and a chronic indwelling urinary catheter are known to have an increased risk of bladder malignancy. However, squamous cell carcinoma (SCC) of the epidermis around a suprapubic cystostomy is relatively rare. Here, we report a case of lower abdominal SCC arising from the suprapubic cystostomy tract. CASE PRESENTATION A 58-year-old man with a complete spinal cord injury was referred to our hospital with a chief complaint of an abdominal mass. Abdominal enhanced computed tomography (CT) showed a 7-cm mass surrounding the suprapubic cystostomy and bilateral inguinal and para-aortic lymph nodes metastasis. Histopathological examination of percutaneous biopsy specimens was performed. The diagnosis was stage IV (cT4N1M1) epidermal SCC, which was treated with palliative external radiation therapy. CONCLUSION The SCC in this case was thought to arise from mechanical stimulus of the suprapubic cystostomy. Physicians and patients should pay careful attention to any signs of neoplasms with long-term indwelling catheters, such as skin changes around the suprapubic cystostomy site. This case presentation is only the fourth report of SCC arising from the suprapubic cystostomy tract in the literature. In cases of unresectable tumors and contraindications to chemotherapy, palliative radiotherapy may lead to disease remission and symptom relief.

Abstract
There are only 7 cases reported in the literature of squamous cell cancer of the bladder in patients performing intermittent self-catheterization (ISC). We report on an eighth case, and the first case described in a patient with a Mitrofanoff continent appendicovesicostomy. A description of the case and review of the literature are presented. Risk factors for squamous cell cancer include recurrent urinary tract infections, keratinising squamous metaplasia (leukoplakia) and local mucosal trauma from intermittent self-catheterization. There is no recognized or validated monitoring program for patients performing ISC who may also have these risk factors. Reasonable protocols may include regular urinary cytology and cystoscopy with random or targeted bladder biopsies. Squamous cell cancer may present late in this cohort of patients and is associated with a dismal prognosis.

Abstract
STUDY DESIGN Retrospective review. OBJECTIVE Spinal cord injury is a known risk factor for bladder cancer. The risk of bladder cancer has been reported at 16-28 times higher than the general population. Earlier studies have identified indwelling catheters as risk factors. We examined the characteristics of bladder cancers in a spinal cord injury (SCI) population. SETTING Long Beach VA Hospital Spinal Cord Injury Unit, Long Beach, California. METHODS We reviewed SCI patients seen and diagnosed with bladder tumors between January 1983 and January 2007. Data collected included time since diagnosis, method of diagnosis, form of bladder management, pathologic type, treatment of the tumor, and outcome. RESULTS A total of 32 patients with bladder cancer were identified out of 1319 seen. Tumors found were 46.9% squamous cell carcinoma (SCC), 31.3% transitional cell carcinoma (TCC), 9.4% adenocarcinoma, and 12.5% mixed TCC and SCC. The primary form of bladder management was 44% urethral catheter for a mean of 33.3 years, 48% external catheter for a mean of 37.4 years, and 8% intermittent catheterization for a mean of 24.5 years. Nineteen patients had a known method of cancer detection with 42% found on screening cystoscopy. CONCLUSIONS The pathologic makeup of the tumors is similar to that reported earlier. Over 50% of patients diagnosed with bladder cancer in our population did not have an indwelling catheter. This suggests that the neurogenic bladder, not the indwelling catheter, may be the risk factor for bladder cancer. Urologists should consider diligent, long-term screening of all patients with SCI for bladder cancer and not just those with indwelling catheters.

Abstract
This article reviews the literature regarding the possible correlation between infection and occurrence of bladder cancer. The PubMed literature database was searched from inception to January 2008. Keywords of bladder, cancer, parasitic, bacterial, viral and infection, were used. Forty studies were included in the review. Several investigators support the idea that schistosomiasis is aetiologically related to the development of bladder cancer in individuals infected with Schistosoma haematobium. Approximately 70% of those with chronic schistosomiasis who have bladder cancer develop squamous cell rather than transitional cell carcinoma. Several investigators suggest that bacteria may play a role in inducing bladder cancer. Clinically, researchers have linked the development of infection, urinary stones and indwelling catheters with bladder cancer. Nevertheless, to date, no prospective study has examined the association between urinary tract infection and bladder cancer risk. The possibility that infection by human papilloma virus (HPV) is a risk factor contributing to bladder cancer has been investigated but no definite conclusions have been drawn. Thus, the debate remains open as to whether there is any direct link between chronic HPV infection and bladder cancer. Only 15 cases of vesical carcinoma have been reported, to date, in the setting of human immunodeficiency virus (HIV). The rare occurrence of bladder cancer during HIV infection and the lack of correlation with the laboratory markers of HIV disease progression may suggest a trivial association between two unrelated disorders. BK virus is oncogenic in newborn hamsters and can transfer to mammalian cells in vitro, but there is little consistent evidence of a link with human bladder cancer. Studies showed no correlation between herpes simplex virus (HSV) and bladder cancer, but bladder cancer becomes infected with HSV much more easily than non-neoplastic urothelium. In conclusion, with the exception of chronic infection with S. haematobium, the association between the occurrence of bladder cancer and chronic bacterial or viral infections could not be confirmed. Prospective studies with large numbers of patients and controls are required to confirm this issue.

Abstract
BACKGROUND The management of neuropathic bladder dysfunction secondary to spinal cord injury is controversial. With the introduction of clean intermittent catheterization (CIC) and anti-cholinergic medication, urinary tract deterioration in this population has declined. Nevertheless, this strategy is problematic for patients who are unable to perform CIC. Suprapubic cystostomy (SPC) is widely viewed as a secondary option, which has a high satisfaction rating among patients, with acceptable clinical efficacy. Despite early reports of long-term renal and bladder complications, recent evidence has demonstrated that improved anti-cholinergic pharmacotherapy and bladder maintenance strategies can enhance SPC efficacy, with diminished morbidity. We set out to review the current literature on SPC in the neuropathic bladder setting and to clarify future management direction. MATERIALS This investigation consisted of a literature search of the MEDLINE and PUBMED databases. Inclusion criteria were related to SPC, indwelling catheterization, urodynamics, spinal cord injury and bladder dysfunction. Our analysis comprised 56 studies, including retrospective analyses and case reports. Investigations regarding surgical technique as well as short and long-term efficacy were also included. RESULTS Early studies reported accelerated renal deterioration and lower urinary tract complications, including stones, recurrent infections and blocked catheters. Procedural complications were generally rare. In contrast, recent investigations, in which patients were managed with anti-cholinergics, frequent catheter changes and bladder washing, and volume maintenance procedures demonstrated similar morbidity profiles to CIC.

Abstract
UNLABELLED Urinary infections constitute one of the main causes of intrahospitalary infections. At the Clinic for the attention of spinal cord injured (SCI) patients, we observed that these can be the causes of high incidence rates as a consequence of multiple risk factors associated with the neurogenic bladder as: vesical urethral reflux, vesicle lithiasis, diverticula and pseudodiverticula, urethral stenosis and permanent or intermittent catheterization. OBJECTIVES To describe forms of presentation of urinary tract infections (UTI) in spinal cord lesioned patients with neurogenic bladder as well as their microbiological behavior. PATIENTS AND METHOD We performed a descriptive, retrospective-type study on 28 patients in order to schedule a neurorestorative treatment for the affectation of the SCI for six months. They all received clinical, imaging test and bacteriologic assessment, that is, urocultures, uretheral and vaginal exudates to determine risk factors, forms of presentation of the infection, as well as associated complications and microbiological behavior. RESULTS The most frequent forms of presentation of infections are: recurrent symptomatic bacteriuria, asymptomatic bacteriuria, bacterial urethritis, bacterial vaginosis and acute pyelonephrites. Most acute germs are: E. coli (for a 60% of isolation), followed by P. mirabilis (14%), K pneumoniae (10%), Staphylococcus sp. (4%), and other enterobacteria. Sensitiveness to aminoglycosides was kept high, where we observed a growing resistance to sulphas (>70%) and fluoroquinolones (>45%) as well as the frequent circulation of multirresistant microorganisms. CONCLUSIONS Clinical peculiarities of urinary infections in the patient with neurogenic bladder, allow to perform more adequate strategies for treatment as to the clinical, microbiological and epidemiologic criteria.

Abstract
The relation between Schistosomiasis and bladder cancer is well-established and accounts for the high rates of bladder cancer in a number of developing countries, including Egypt. In developed countries, transitional cell carcinoma is the predominant type of bladder cancer, whereas in Schistosomiasis-endemic regions, squamous cell carcinoma is the most common type. In this review, experimental and observational data on infection, inflammation, and bladder cancer are summarized with special emphasis on transitional cell carcinoma. Findings from numerous studies suggest that inflammation is likely to have an important role in bladder carcinogenesis in developed countries. Future studies need to focus in greater detail on risk factors that increase inflammation of the bladder, examine genetic susceptibility to inflammatory pathways, and include markers of inflammation measured prior to cancer diagnosis. Understanding the role of inflammation on transitional cell carcinogenesis may provide important insights on how to prevent the sixth most common cancer in the United States.

Abstract
Deaths from metastatic carcinoma are almost exclusively viewed as wholly natural deaths. However, if it can be shown that a cancer has arisen as a result of a prior traumatic injury and the body's healing response to the injury, or treatment thereof, then in select cases, the manner of death shall reflect that of the precipitating injury. This case report is that of a woman who was rendered quadriplegic from spinal cord injury sustained in a motor vehicle crash when she was 22 years old. She died at the age of 49 years from widely metastatic squamous cell carcinoma of the urinary bladder. Her bladder cancer most likely arose from decades-long chronic irritation of the bladder epithelium by physical contact with an indwelling Foley catheter and urinary infections. Over the years, the chronic bladder irritation likely precipitated metaplastic, dysplastic, and finally neoplastic changes of the bladder epithelium, providing a link between her spinal cord injury, the indwelling Foley catheter, and her bladder cancer, engendering an accidental manner of death. The manner of death reflected the circumstances of her injury that predisposed her to the cancer that eventually caused her death.

Abstract
In the past, renal failure was the leading cause of death after spinal cord injury (SCI). Today mortality from SCI has declined dramatically partly owing to the improved management of urologic dysfunction associated with SCI. The goals of bladder management in spinal cord injury patients are intended to (1) ensure social continence for reintegration into community, (2) allow low-pressure storage and efficient bladder emptying at low detrusor pressures, (3) avoid stretch injury from repeated overdistension, (4) prevent upper and lower urinary tracts complications from high intravesical pressures, and (5) prevent recurrent urinary tract infections. This article provides an overview of neurogenic bladder dysfunction associated with SCI and current management options.

Abstract
INTRODUCTION Although many studies have reported that upper urinary tract stones in patients with nonfunctioning kidneys are associated with malignancy, the incidence and frequency of the tumor cell type remain unclear. Therefore, we aimed to investigate the percentage of malignancies present in patients with nonfunctional kidneys who underwent nephrectomy. MATERIALS AND METHODS From July 1995 to December 2005, we reviewed a total of 47 patients who underwent nephrectomy to treat a nonfunctional kidney due to urolithiasis with clinical symptoms such as complicated chronic infection. Pathology revealed malignancies in 24 patients. Relationships between clinical presentations and malignancy were analyzed. RESULTS Malignancy was diagnosed in 24 patients after nephrectomy. Image studies revealed possible malignancy in only 7 patients before surgery. A high incidence (17/24) of transitional cell carcinoma was noted. The remaining malignancies included 5 renal cell carcinomas, 1 squamous cell carcinoma and 1 epidermoid carcinoma. There were 5 deaths during the follow-up interval. CONCLUSIONS There is a high incidence of malignancy associated with nonfunctional kidney caused by stone disease. We suggest careful examination of the pathological specimens from nephrectomy for nonfunctional kidney regardless of clinical manifestations.

Abstract
OBJECTIVE The role of urinary tract diseases in bladder cancer (BC) etiology is not well established. To gain more insight on the role of urinary tract diseases in bladder cancer risk, we analyzed data from a large case-control study of bladder cancer. METHODS Epidemiological data were collected via in-person interview. Logistic regression analyses were used to estimate BC risk in association with prior history of urinary tract diseases. RESULTS A total of 659 BC patients and 689 age-, gender-, -ethnicity matched controls were included in the analyses. Increased bladder cancer risk was associated with history of cystitis (OR = 1.52, 95% CI: 1.12, 2.06), however, the risk was attenuated for infections diagnosed >1 year from the time of BC diagnosis or interview. In contrast, a history of four or more kidney infections was associated with a significant decreased risk of BC (OR=0.17, 95% CI: 0.04, 0.69), and there was a significant dose-response relationship between number of episode and BC risk (P for trend = 0.002). The joint effect of smoking with cystitis, kidney infection, bladder stone, kidney stone, and prostate infection was studied but revealed no significant interaction between smoking and these urinary tract diseases. CONCLUSION This study does not support the concept that urinary tract infections play a major role in the development of BC. Our study has the strength of collecting diagnosis time data of urinary tract diseases to allow analyzing the impact of timing of diagnosis between cancer and urinary tract diseases. This enables us to effectively address the issue of detection bias in case-controls studies of prior urinary diseases and BC.
