Evaluating the effectiveness of early urethral catheter removal combined with intermittent catheterization for promoting early recovery of bladder function after laparoscopic radical hysterectomy: a study protocol for a randomized controlled trial.

BACKGROUND: Bladder dysfunction, notably urinary retention, emerges as a significant complication for cervical cancer patients following radical hysterectomy, predominantly due to nerve damage, severely impacting their postoperative quality of life. The challenges to recovery include insufficient pelvic floor muscle training and the negative effects of prolonged postoperative indwelling urinary catheters. Intermittent catheterization represents the gold standard for neurogenic bladder management, facilitating bladder training, which is an important behavioral therapy aiming to enhance bladder function through the training of the external urethral sphincter and promoting the recovery of the micturition reflex. Nevertheless, gaps remain in current research regarding optimal timing for intermittent catheterization and the evaluation of subjective symptoms of bladder dysfunction. METHODS: Cervical cancer patients undergoing laparoscopic radical hysterectomy will be recruited to this randomized controlled trial. Participants will be randomly assigned to either early postoperative catheter removal combined with intermittent catheterization group or a control group receiving standard care with indwelling urinary catheters. All these patients will be followed for 3 months after surgery. The study's primary endpoint is the comparison of bladder function recovery rates (defined as achieving a Bladder Function Recovery Grade of II or higher) 2 weeks post-surgery. Secondary endpoints include the incidence of urinary tract infections, and changes in urodynamic parameters, and Mesure Du Handicap Urinaire scores within 1 month postoperatively. All analysis will adhere to the intention-to-treat principle. DISCUSSION: The findings from this trial are expected to refine clinical management strategies for enhancing postoperative recovery among cervical cancer patients undergoing radical hysterectomy. By providing robust evidence, this study aims to support patients and their families in informed decision-making regarding postoperative bladder management, potentially reducing the incidence of urinary complications and improving overall quality of life post-surgery.

Hydrophilic catheters for intermittent catheterization and occurrence of urinary tract infections. A retrospective comparative study in patients with spinal cord Injury.

BACKGROUND: Neurogenic bladder dysfunction is a major problem for spinal cord injury (SCI) patients not only due to the risk of serious complications but also because of the impact on quality of life. The main aim of this study is to compare the rate of urinary tract infection (UTI) associated with hydrophilic-coated catheters versus uncoated polyvinyl chloride (PVC) catheters among SCI patients presenting with functional neurogenic bladder sphincter disorders. METHODOLOGY: This was a retrospective cohort study from 2005 to 2020 including adult male or female patients who have an SCI at least more than 1 month ago with neurogenic bladder dysfunction and were using intermittent catheterization (single-use hydrophilic-coated or the standard-of-care polyvinyl chloride uncoated standard catheters) at least 3 times a day to maintain bladder emptying. RESULTS: A total of 1000 patients were selected and recruited through a stratified random sampling technique with 467 (47.60%) patients in the uncoated catheter arm and 524 (52.60%) in the coated catheter groups. The three outcome measures, namely: symptomatic UTI, Bacteriuria, and pyuria were significantly higher in the group using uncoated polyvinyl chloride (PVC) catheters compared to hydrophilic-coated catheters at the rate of 79.60% vs.46.60%, 81.10% vs. 64.69, and 53.57% versus 41.79% respectively. Males, elder patients, longer duration, and severity of SCI were associated with increased risk of symptomatic UTI. CONCLUSIONS: The results indicate a beneficial effect regarding clinical UTI when using hydrophilic-coated catheters in terms of fewer cases of symptomatic UTI. Bacteriuria is inevitable in patients with long-term catheterization, however, treatment should not be started unless the clinical symptoms exist. More attention should be given to the high-risk group for symptomatic UTIs.

Factors associated with symptomatic urinary tract infection in persons with spinal cord lesions who perform clean intermittent catheterization with single-use catheters.

OBJECTIVES: To investigate factors associated with symptomatic urinary tract infection (sUTI) in persons with chronic spinal cord lesion (SCL) who were using single-use catheters for intermittent self-catheterization (ISC). METHODS: Among respondents to an internet survey on the burden of illness on persons with SCL who were considered to be able to perform ISC, 111 persons using single-use catheters were included to examine factors associated with self-reported sUTI by univariate as well as multivariable analysis. RESULTS: The incidence of sUTI was significantly higher in males than in females (56.9% vs. 31.6%, p = .011), persons with stocks of antibiotics than those without it (82.9% vs. 28.6%, p < .011), and persons with more frequent bleeding during catheterization than those with less frequent bleeding (100% vs. 46.5%, p = .036). The incidence did not significantly differ between respective groups when various variables were evaluated by other characteristics of the participants, adherence to ISC procedures, and complications. On multivariable analysis, male gender and stocks of antibiotics were significant independent factors for sUTI. CONCLUSIONS: Male gender and stocks of antibiotics were associated with sUTI in persons with SCL who were performing ISC with single-use catheters.

New micro-hole zone catheter reduces residual urine and mucosal microtrauma in a lower urinary tract model.

Urinary tract infections (UTIs) are the main complication associated with clean intermittent catheterization (CIC) and are facilitated by post-void residual urine and trauma to the mucosa during voiding. The risk of UTI may be diminished by reducing the residual volumes and preventing microtrauma caused by mucosal suction through the eyelets of conventional eyelet catheters (CEC). A new micro-hole zone catheter (MHZC) was developed and tested in an ex vivo porcine lower urinary tract model and in vivo, in pigs, against a CEC. It was shown that, irrespective of the micro-hole diameter, the new catheter ensured increased flowrates and significantly lower residual volumes at the first flow-stop. Furthermore, with a micro-hole diameter of 0.4 mm, mucosal suction was virtually eliminated, regardless of the insertion depth or simulated intra-abdominal pressure mimicking sitting or standing humans. Pressure profile experiments and endoscopy studies indicated that the bladder gradually folds against the drainage tip of the new catheter, without blocking the flow, and, unlike with the CEC, sharp pressure variations and flow-stops did not occur during voiding. The MHZC outperformed the CEC in all tested scenarios and decreased residual volumes, thus potentially decreasing the risk of UTIs.

Investigation of anxiety levels in caregivers who perform clean intermittent catheterization on their children and affecting factors.

PURPOSE: The study aimed to determine the anxiety levels of caregivers who performed clean intermittent catheterization (CIC) on their children and the factors affecting them. METHODS: This descriptive study was conducted between January 6, and May 29, 2023 with caregivers of 42 patients who were followed up by the pediatric nephrology outpatient clinic of a university for CIC. The study data were collected using the "Participant Information Form" and the "State and Trait Anxiety Scale." RESULTS: According to the results, of the children included in the study, 73.8% were female, 64.3% were diagnosed with spina bifida (SB), and 76.2% received CIC applications 4-6 times a day. All the caregivers were mothers, and 76.2% received CIC training from a doctor. However, 78.6% of them found the training insufficient, leading them to rely on self-experimentation when applying CIC to their own children. None of the caregivers received information or training on the CIC application from nurses, and there were no home visits or telephone counseling provided after the hospital discharge. The mean score for the state anxiety scale among the caregivers was 45.90 ± 10.57, while the mean score for the trait anxiety scale was 46.92 ± 8.43. Significantly higher mean trait anxiety scores were observed among caregivers with chronic diseases who did not receive training on the CIC application (p < 0.05). Additionally, caregivers of children who experienced 3-4 urinary tract infections (UTIs) within the last 3 months also had significantly higher mean trait anxiety scores (p < 0.05). The mean trait anxiety level scores of caregivers of children who had 3-4 UTIs in the last 3 months were significantly higher (p < 0.05). CONCLUSIONS: It was concluded that caregivers' lack of training on CIC implementation, having chronic disease, and having frequent UTIs in their children were effective on anxiety levels.

A consensus statement on when to start clean intermittent self-catheterization: An untapped resource?

BACKGROUND: Clean intermittent self-catheterisation (CISC or ISC) is used by patients/carers to empty the bladder if needed. Sometimes the urethral lumen leading out of the bladder is blocked; sometimes, the bladder (detrusor) muscle itself or the autonomic motor nerves innervating the bladder are damaged, resulting in a failure of the detrusor muscle to work, leading to a failure of the bladder being able to empty adequately. Prior consensus as to the indications and timing of CISC has yet to be provided. This article aims to provide a multidisciplinary consensus view on this subject. CONCLUSION: It is evident that every patient needs to be considered individually, bearing in mind the symptoms and investigations to be considered. We emphasise the importance of considering the term Bladder Voiding Efficiency (BVE). One group of patients who might find CISC helpful are those with a neurological disorder; these include spinal injury patients, multiple sclerosis, Parkinson's, and a condition called cauda equina. Sometimes bladder problems are treated with anticholinergics, and others may be treated with Botox. These may cause the bladder not to empty at all, which is good for leaks but needs self-catheterisation to empty the bladder. In the past, hospitals used a permanent catheter called an 'indwelling' or a 'suprapubic' catheter. These can have side effects, including infections, stones, and pain. For CISC, disposable catheters are the best option for patients as they come in different sizes and styles to provide individualised care. In conclusion, we would like hospitals to consider each patient separately and not use a general 'one-size-fits-all' bladder function for these patients.

Evaluation of Quality of Life and Self-reported Complications in Patients With Clean Intermittent Catheterization: An Observational Study.

PURPOSE: This study sought to determine health-related quality of life and self-reported complications associated with clean intermittent catheterization (CIC). DESIGN: Observational, cross-sectional study. SUBJECTS AND SETTING: The target population was patients cared for by the urology department at Hospital 12 de Octubre in Madrid, Spain, undergoing CIC for chronic urinary retention of any etiology (neurogenic bladder dysfunction, neobladder, and other). The sample comprised 50 respondents with a mean age of 49 years; a majority (66%, n = 33) were female. Participants performed an average of 4 CICs. METHODS: All participants completed the ISC-Q (Intermittent Self-Catheterization Questionnaire) and a questionnaire about CIC-associated complications. Data were collected in February 2019. RESULTS: A vast majority of respondents (98%, n = 49) indicated preparation for catheterization was simple, and 76% (n = 38) indicated the catheter was easy to insert. One in 5 (20%, n = 10) considered carrying catheters and supplies inconvenient, though 58% (n = 29) indicated it was easy to dispose of the catheters outside the home. Most respondents (98%, n = 49) indicated they felt self-conscious about their need to self-catheterize, and 16% (n = 8) felt that CIC created limitations when visiting friends and family. The most frequent complication was symptomatic urinary tract infections (UTIs); participants reported an average of 1.7 UTIs in the last year. Additional complications, such as epididymo-orchitis, urethral stenosis, and urethral bleeding, were reported by less than 5% (n = 2) of participants. CONCLUSIONS: Participants managed by CIC for chronic urinary retention of any cause reported acceptable levels of satisfaction with the procedure. The reported incidence of complications was low, except for UTIs.

[Intermittent catheterization: What are the environmental impacts and how can they be reduced?] / Sondage intermittent : quels sont les impacts environnementaux et comment les réduire ?

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.

Risk factors associated with recurrent febrile urinary tract infection in children with neurogenic bladder who perform clean intermittent catheterization.

OBJECTIVE: To identify the clinical and urodynamic risk factors associated with the development of recurrent febrile urinary tract infections (FUTIs) in children with neurogenic bladder (NB) who perform clean intermittent catheterization (CIC). METHODS: Children with NB receiving CIC were prospectively enrolled from January to December 2019 and followed up prospectively for 2 years. All data were compared between occasional (0-1 FUTI) and recurrent FUTIs (≥2 FUTI) groups. In addition, the risk factors for recurrent FUTIs in children were evaluated. RESULTS: Complete data from 321 children were analyzed. Occasional FUTIs occurred in 223 patients, and 98 patients experienced recurrent FUTIs. Univariate and multivariate analyses, showed late-initiation and low-frequency CIC, vesicoureteral reflux (VUR), small bladder capacity and low compliance, and detrusor overactivity were associated with an increased risk of recurrent FUTIs. Children with high-grade VUR (grades IV-V) had a higher risk of recurrent FUTIs than those with low-grade VUR (grades I-III) (odds ratio [OR]: 26.95 vs. OR: 4.78, p < 0.001). CONCLUSIONS: Our study suggests that late-initiation and low-frequency CIC, VUR, small bladder capacity and low compliance, and detrusor overactivity were associated with recurrent FUTIs in patients with NB. In addition, high-grade VUR is a crucial risk factor for recurrent FUTIs.

Urinary tract infection in patients with lower urinary tract dysfunction.

Lower urinary tract dysfunction (LUTD) is becoming more common in aging societies worldwide. In patients with LUTD, the risk of urinary tract infection (UTI) rises due to several distinct mechanisms, including easy bacterial access to the urinary tract, impaired bacterial washout, and an impaired innate defense system. The pathophysiology of LUTD varies depending on whether it is neurogenic or non-neurogenic, as well as by gender; therefore, the etiology and characteristics of UTI differ according to the type of LUTD. Patients with neurogenic LUTD, especially those with spinal cord injury, have a high risk of febrile UTI, and strict bladder management is required to prevent UTI. Clean intermittent catheterization with or without appropriate pharmacological therapy is also strongly recommended for patients with neurogenic LUTD at risk of febrile UTI, unable to void, or with high post-void residual volume. In contrast, both male and female patients with non-neurogenic LUTD have a lower risk of symptomatic UTI. There is insufficient evidence for non-neurogenic LUTD regarding the association between symptomatic UTI but not asymptomatic bacteriuria and LUTD severity, including the presence of post-void residual volume, or whether therapeutic intervention for LUTS reduces the incidence of UTI, particularly in male patients. In this narrative review, we aimed to highlight the pathogenesis, epidemiology, and management of UTI in patients with LUTD.

Management of complex ischial-urethral fistula in neurogenic patients performing clean intermittent self-catheterization.

INTRODUCTION: Neurogenic patients performing clean-intermittent self-catheterization (CIC) may develop an urethral erosion, resulting in ischial-urethral fistulas (I-UF). In this work we present our single-center experience in dealing with this peculiar complication. METHODS: In this work we included all neurogenic patients performing CIC treated at out Institution for I-UF. All patients had a spinal cord injury or myelomeningocele. We extracted from the patients' medical records the surgical management and postoperative clinical data. We defined failure the persistence of the fistula at X-ray contrast fistulography, retrograde urethrography, or uretrocystoscopy. RESULTS: We treated 11 patients (8 spinal cord injury, 3 myelomeningocele). Four patients have been treated with the placement of a new generation urethral stent (Uventa) after surgical toilette of the skin ulcer and placement of a temporary suprapubic catheter. All patients demonstrated a complete healing of the urethral lesion at stent removal and continued CIC without any difficulty. Four patients have been treated with perineal urethroplasty, requiring a buccal mucosal graft in two cases. In two patients a suprapubic permanent catheter was placed for a simpler bladder management due to the patients' comorbidities. In one case the incidental finding of an high grade muscle invasive urothelial bladder cancer, made it mandatory to perform an uretheroileocutaneostomy. CONCLUSIONS: This work represent a unique series of I-UF in neurogenic patients performing CIC. Surgical urethral reconstruction, often with the use of buccal mucosa in large lesions, may be a difficult solution in neurogenic patients, new generation stents (Uventa) represent a minimally invasive, effective, and safe alternative.

Hydrophilic versus non-hydrophilic catheters for clean intermittent catheterization: a meta-analysis to determine their capacity in reducing urinary tract infections.

INTRODUCTION: Clean intermittent catheterization (CIC) is associated with an increased risk of urinary tract infections (UTI), urethral trauma, urethral stenosis, hematuria, and pain. The first catheters were developed of polyvinyl carbon (PVC). Several types of catheters have been developed to reduce these complications, such as those with hydrophilic coating. OBJECTIVE: To conduct a systematic review and meta-analysis to evaluate the effectiveness of hydrophilic coated catheters compared to uncoated catheters on the rate of UTI in patients using CIC. METHODOLOGY: A systematic literature search was performed in OVID, Embase, Scopus, Web of Science, PubMed, and CENTRAL databases. Randomized controlled trials (RCTs) or randomized crossover trials comparing UTI and hematuria rates in patients using hydrophilic vs. non-hydrophilic catheters for CIC were identified. The selected trials were evaluated for risk of bias using the "Revised Cochrane risk-of-bias tool for randomized trials (RoB 2)." The results were expressed as a risk ratio (RR) with a 95% confidence interval (CI), under a random-effects model. Data were analyzed using Review Manager 5.4 software. RESULTS: Nine studies with a total of 525 patients in CIC were analyzed. Overall, the use of hydrophilic catheters had a lower risk of UTIs compared to uncoated catheters (RR = 0.78; 95% CI 0.62-0.97; I2 = 37%). Five of the studies include patients > 18 years, showing a reduction of UTIs with the use of hydrophilic catheters (RR = 0.83; 95% CI 0.74-0.93; I2 = 0%). There was no difference in UTI development when comparing single-use uncoated vs hydrophilic catheters. However, heterogeneity was high (RR = 0.77; 95% CI 0.59-1.00; I2 = 57%). Regarding hematuria risk reduction, we were unable to identify differences between the use of hydrophilic catheters compared to uncoated catheters (RR = 1.02; 95% CI 0.66-1.60). CONCLUSION: We found a risk reduction of UTIs associated with using hydrophilic catheters in adults, with low heterogeneity. Regarding hematuria, significant differences were not proved. We do not find a significant difference in UTI risk reduction in the pediatric population. Urethral trauma presence could not be meta-analyzed due to a lack of information reported.

Analysis of factors affecting permanent clean intermittent catheterization and bladder function after primary neurosurgical repair of lipomyelomeningocele.

AIMS: This study was conducted to identify potential risk factors for permanent clean intermittent catheterization (CIC) and incontinence in patients with lipomyelomeningocele (LMMC) and evaluate how LMMC affects bladder function prognosis, measured by urodynamic (UD) score. METHODS: This retrospective study analyzed the electronic health records of patients who underwent primary neurosurgical repair for LMMC at a single tertiary referral center between January 2012 and December 2016 and were followed at least 3 years after surgery. Data regarding bladder function were obtained from medical records for multiple time points, including before surgery, after surgery but before hospital discharge, 3 months after surgery, and at outpatient visits during follow-up. RESULTS: This study enrolled 120 patients. At a mean follow-up of 62.6 ± 13.9 months after primary neurosurgical LMMC repair, 22 (18.3%) patients continued to require CIC for bladder emptying, only 7 (31.8%) of whom maintained bladder continence. A multivariate logistic regression model identified age at the time of surgery and the type of LMMC as significant presurgical prognostic risk factors for permanent CIC. In addition, postoperative urinary retention and a UD score greater than or equal to 5 measured 3 months after surgery were identified as significant postsurgical risk factors for permanent CIC and urinary incontinence. A linear mixed model adjusted for age at the time of surgery showed that patients with a transitional or chaotic LMMC type were more likely to experience gradual bladder function decline than patients with other LMMC types. CONCLUSIONS: This study identified both presurgical (age at the time of surgery, LMMC type) and postsurgical (postoperative urinary retention, UD score greater than or equal to 5 at 3 months postsurgery) risk factors for permanent CIC and urinary incontinence. In addition, LMMC type was identified as a prognostic risk factor for bladder function decline. These results will enhance the current understanding of bladder function outcomes in patients who undergo surgical treatment for LMMC.

Impact of early self-clean intermittent catheterization in orthotopic ileal neobladder: prospective randomized study to evaluate functional outcomes, continence status and urinary tract infections.

BACKGROUND: Urinary diversions after radical cystectomy (RC) have a significant impact on quality of life and body image. Particularly for orthotopic neobladder (ONB), the rate of continence, urinary retention and urinary tract infections can impact on patient's quality of life. The aim of this study was to investigate whether early clean intermittent catheterization (CIC) might improve functional outcomes, continence status, and reduce the incidence of UTIs in patients with ONB. METHODS: In this prospective randomized study patients were divided in two groups. Patients were on a standard postoperative care (group A) or started CIC within the first postoperative month (group B). All patients were evaluated postoperatively at 1, 3, 6, and 9 months after ONB. The CIC was executed 4 times/daily after each voluntary micturition. The postoperative evaluation included: post-void residual volume (PVR), urine analysis and culture, number of pads/day and the self-administrated questionnaire International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). RESULTS: Thirty-nine male and 8 female patients underwent laparoscopic or robotic RC with intracorporeal ONB (37 U shaped and 10 Padua reconstructions). At the first follow up, mean PVR was in group A and B, 136.5 mL and 125.7 mL (P value: 0.105), respectively. The ICIQ-UI SF mean score was 16.2 and 17.1 (P value: 0.243) respectively and the mean no. of pads/day was 3 in both groups. 15 patients in group A and 10 in group B reported episodes of symptomatic UTIs. At 3, 6 and 9 months follow up after surgery the PVR and the ICIQ-UI SF scores were significantly improved (P value <0.0001). The number of pads decreased to 2 pads/day in group A and 1 in group B at 9 months. The episodes of UTIs significantly decreased over the time (P value <0.0001). CONCLUSIONS: Our data support the early introduction of self CIC in patients with ONB after RC. The CIC was significantly associated a reduced risk of incontinence, urinary retention, and UTI with significant improvement in QoL. These encouraging data need to be confirmed by further investigations with a larger number of patients.

Patient Support Program and Healthcare Resource Utilization in Patients Using Clean Intermittent Catheterization for Bladder Management.

PURPOSE: The primary purpose of this study was to evaluate the impact of a patient-centered, chronic care self-management support program of clean intermittent catheterization (CIC) on emergency department (ED) visits and hospitalizations within the first 30 days of starting CIC. Secondary research objectives were to compare reuse of catheters, adherence to healthcare provider-instructed frequency of CIC, and reasons for nonadherence. DESIGN: A correlational survey design with 2 respondent groups. SUBJECTS AND SETTING: Four hundred forty-five respondents met inclusion criteria for this study; 321 respondents enrolled in an intermittent catheter manufacturer-supported CIC support program, and 124 respondents were not enrolled in a support program (comparison group). METHODS: Participants completed a 37-item online questionnaire designed for purposes of this study. Chi-square test was used to assess differences in the proportions of patients with ED visits and overnight hospital admissions comparing respondents enrolled in the patient support program to those not enrolled. Regression analyses were performed to estimate the effect of the CIC support program on ED visit events and on hospital overnight stays. RESULTS: Within the first month of CIC initiation, 16.1% and 10.2% of the respondents in the comparison group reported at least 1 ED visit and at least 1 overnight hospital stay, respectively. Respondents participating in the CIC support program experienced a 47% decrease in ED visits (adjusted rate ratio: 0.53; 95% confidence interval: 0.30-0.94, P = .036) and a 77% decrease (adjusted rate ratio: 0.24; 95% confidence interval: 0.10-0.62, P = .002) in hospital overnight stays within the first month of CIC initiation, while controlling for age, sex, education, duration of CIC use, region, health insurance status, and medical conditions necessitating CIC. Respondents in the CIC support program group reported an 8% higher adherence rate with the healthcare provider-instructed frequency of CIC usage compared to the comparison group (88% vs 80%, P = .039). CONCLUSIONS: The burden of CIC-related complications within the first month of CIC initiation is significant. A patient-centered, chronic care self-management program for CIC was associated with fewer ED visits and overnight hospital stays during the first month of CIC and improved adherence to prescribed frequency of CIC use.

Value of sufficient clean intermittent catheterization in urinary tract infection and upper urinary tract protection in children with neurogenic bladder.

INTRODUCTION: Clean intermittent catheterization (CIC) is a mainstay in the management of neurogenic bladder. OBJECTIVE: To assess the effect of CIC on urinary tract infection and upper renal tract function in pediatric patients with neurogenic bladder, and the influence of duration of CIC on these variables. STUDY DESIGN: A retrospective study was performed in 67 pediatric patients with neurogenic bladder who started CIC between 2014 and 2019 at our institution. The febrile urinary tract infection (fUTI) rate, renal pelvis diameter (measured by antero-posterior renal pelvis diameter, APPD), bladder wall thickness (BWT) on ultrasound, and creatinine level at 6 months and 12 months of CIC were compared with baseline in all patients. The grade of vesicoureteral reflux (VUR) at 12 months of CIC were also compared with baseline. RESULTS: There were no significant differences compared with baseline after 6 months of CIC in the rate of fUTI, APPD, and BWT (p > 0.05); however, all of these parameters significantly improved after 12 months of CIC (p < 0.05). The VUR grade was significantly reduced after 12 months of CIC(p = 0.03). There was no significant change in serum creatinine level with any duration of CIC (both p > 0.05). DISCUSSION: Continuing CIC for more than 6 months had a beneficial influence on protecting the upper urinary tract. Complications of CIC, such as recurrent fUTI and lower urinary tract trauma, are more likely to occur in the early stage of CIC due to poor technique by the caregivers and poor patient compliance underscoring the importance of caregiver education. Study limitations include the retrospective nature and small sample size. CONCLUSION: CIC for less than 6 months may have limited influence on renal protection; however, a longer duration of CIC (12 months) resulted in significant improvement in outcomes. This study demonstrates the importance of proper caregiver education to establish standardized CIC techniques and to improve CIC quality.

The Patient Pathway for Men with Chronic Urinary Retention: Treatments, Complications, and Consequences.

OBJECTIVE: To explore the treatment options for chronic urinary retention (CUR) in men, including treatment-related complications and consequences. METHODS: This retrospective cohort study included male patients diagnosed with a non-neurogenic, symptomatic and/or high-risk, CUR >150 mL in a large Dutch non-academic teaching hospital. Data for treatments, complications, and consequences (eg, diagnostics, additional treatments, and hospital contact) were recorded and incidence rate ratios (IRRs) were calculated. RESULTS: We enrolled 177 patients (median age, 77 years; range, 44-94) with a median follow-up of 68 months (range, 1-319) during which they had a median of 8 events (range, 1-51). Most patients initially received a urethral catheter (74%) and some form of catheterization as their final treatment (87%). Compared with non-surgical cases, catheterization was more likely to be stopped after de-obstructive prostate surgery (IRR, 4.18; P < 0.001). Urinary tract infection (IRR, 3.68; P < 0.001) and macroscopic hematuria (IRR, 5.35; P < 0.001) were more common with catheterization, but post-renal problems were more likely in patients with no catheterization (IRR, 25.36; P < 0.001). The lowest chance of complication was with clean intermittent catheterization, and complications were usually managed in outpatient (77%) or emergency (6%) departments, rather than by admission (17%). CONCLUSION: Most patients require catheterization for CUR, with clean intermittent catheterization preferred due to its comparatively lower complication risk. De-obstructive prostate surgery increases the chance of stopping catheterization and may be considered in suitable cases.

Effects of hydrophilic coated catheters on urethral trauma, microtrauma and adverse events with intermittent catheterization in patients with bladder dysfunction: a systematic review and meta-analysis.

BACKGROUND: Hydrophilic coated catheters are recommended to reduce the side effects of intermittent catheterization (IC) in patients with bladder dysfunction. However, there is lack of Level one evidence to support the use of this intervention. SEARCH METHODS: Several electronic databases were systematically searched to evaluate complication incidences for hydrophilic coated (HC) and non-hydrophilic catheters (NHC). RESULTS: Twelve studies were eligible for inclusion in the review. The meta-analyses exploring microscopic hematuria frequencies (RR = 0.69; 95% CI 0.52-0.90) and urethral stricture frequencies (RR = 0.28; 95% CI 0.13-0.60) showed a lower risk ratio associated with HC in comparison to NHC, whereas gross hematuria was no statistically significant difference in two groups. Subgroup analyses of gross hematuria which was grouped according to "catheterization frequency", "single/multiple catheterization" and "self/other catheterization" were performed and the values of combined RR were also no statistically significant difference. CONCLUSIONS: Compared with non-hydrophilic catheters, the hydrophilic coated catheters have positive significance in reducing the incidence of urethral microtrauma and the urethral stricture. However, more studies are warranted for evaluating effects of hydrophilic coated catheters on the incidence of gross hematuria.

Efficacy and Safety of AbobotulinumtoxinA in Patients with Neurogenic Detrusor Overactivity Incontinence Performing Regular Clean Intermittent Catheterization: Pooled Results from Two Phase 3 Randomized Studies (CONTENT1 and CONTENT2).

BACKGROUND: For patients with neurogenic detrusor overactivity incontinence (NDOI), treatment with oral medications is often unsatisfactory. OBJECTIVE: To assess the efficacy and safety of abobotulinumtoxinA (aboBoNT-A) for NDOI. DESIGN, SETTING, AND PARTICIPANTS: Two randomized, double-blind phase 3 studies (CONTENT1, NCT02660138; CONTENT2, NCT02660359) enrolled patients with NDOI who were regularly performing clean intermittent catheterization (CIC) and were inadequately managed with oral therapy. Pooled results from the first placebo-controlled treatment cycle are reported. INTERVENTION: Patients received injections of aboBoNT-A 600 U (n = 162) or 800 U (n = 161) or placebo (n = 162) into the detrusor muscle. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was the mean change from baseline in NDOI episodes per week at week 6. Secondary endpoints reported are the proportion of patients with no NDOI episodes, the volume per void, urodynamic parameters, and quality of life (QoL). Safety was also assessed. Statistical analyses were conducted for the pooled study populations (each aboBoNT-A dose vs placebo). RESULTS AND LIMITATIONS: At week 6, NDOI episodes per week were significantly reduced in each aboBoNT-A group versus placebo (both p < 0.001) and the volume per void had significantly increased. Approximately one-third of patients in each aboBoNT-A dose group reported no NDOI episodes versus 3% of patients in the placebo group. Reductions in urinary incontinence (UI) were reflected in significantly greater improvements in UI-related QoL in the aboBoNT-A groups versus placebo. Urodynamic parameters (bladder capacity and detrusor pressure) were significantly improved with each aboBoNT-A dose versus placebo. Each aboBoNT-A dose was well tolerated. Symptomatic urinary tract infection was the most frequent treatment-emergent adverse event, with incidence comparable across the aboBoNT-A and placebo groups. The studies were terminated prematurely owing to slow recruitment and were not designed for statistical comparison between the two aboBoNT-A doses. CONCLUSIONS: Intradetrusor aboBoNT-A is an effective treatment and alternative option for patients with NDOI who have an inadequate response to oral anticholinergics and are already performing CIC. PATIENT SUMMARY: In patients with bladder muscle overactivity caused by neurological conditions (multiple sclerosis or spinal cord injury) and resulting in urinary incontinence, abobotulinumtoxinA injections improved their symptoms and bladder function, with no unexpected effects.

INTRODUCTION: Clean Intermittent Catheterization (CIC) is the method of choice for bladder emptying in patients having bladder emptying disorders, acquired or pharmacologically induced, whether it is neurologically related or not. The aim of this study is to assess the theoretical and practical knowledge of general practitioners (GP) on CIC. MATERIALS: Observational prospective study (anonymous online questionnaire) was conducted with 224 GP between March and April 2020. Each physician had to complete a questionnaire about the definition of CIC, its indications and usage, the indications of urine culture, antibiotic therapy, and the complications of this method of drainage. RESULTS: Only 18.3% of GP that took part in the study gave an exact definition of CIC. As to the importance of it, 67.9% responded that it protects the upper urinary tract and 37.1% that it prevents urinary tract infections (UTI). Fifty-two per cent of physicians were unaware of the regular frequency at which it should carry out a day. Fifty eight percent prescribed sterile gloves and 57.1% an antiseptic. UTI was considered as the main complication of CIC by 87.1% of physicians and 35.7% requested a systematic urine culture for patients under CIC. For patients with an asymptomatic bacteriuria, 65.6% of GP prescribed antibiotic therapy. CONCLUSION: GP need to improve their knowledge of SIP, its framework, indications, modalities, and the way to deal with colonization or urinary tract infection. This will improve the management of impacted patients.
