UNASSIGNED: Spinal cord injury often results in neurogenic bladder affecting storage or emptying functions of the bladder. Clean intermittent catheterization (CIC) is considered the gold standard for patients with neurogenic bladder dysfunction. Our study aims to assess the adherence of patients to CIC following discharge from rehabilitation.
UNASSIGNED: PRIMARY: To assess the adherence of patients with spinal cord injury in the community to self-CIC within 12 months of discharge. SECONDARY: To study the reasons and analyze the factors associated with discontinuation of CIC and to assess the perception of patients regarding CIC.
UNASSIGNED: Prospective follow-up of a retrospective cohort in 121 individuals with paraplegia who were trained to do CIC for bladder management. After obtaining telephonic consent, a questionnaire-based interview was conducted.
UNASSIGNED: Out of 121 patients, 97 (80.2%) were males and 24 (19.8%) were females. The mean age was 35.8 ± 11.6 years. About 89 (73.6%) patients were continuing CIC as the primary mode of bladder management after discharge. However, only 18 (15%) patients were fully compliant with the CIC technique, 71 (59%) were partially compliant and 32 (26%) patients discontinued CIC. Reasons for the discontinuation of CIC included medical complications (78%), including leaks, recurrent UTI, hematuria, ulcers, back pain, and spasticity, and other factors like difficulty in following the timing of CIC (12.5%), issues with positioning (3.1%), and difficulty in restricting fluid intake (6.3%).
UNASSIGNED: This study highlights the need for regular follow-up as well as education of patients regarding CIC technique, complications, care, and hygiene while doing CIC which can result in improved adherence to CIC.

Urinary catheters have been used for more than 3000 years, although materials have changed from wood to silver to rubber. Research continues to try and find the optimal catheter materials, which improve safety and quality of life. Advantages when comparing newer catheter materials are not always obvious but catheters coated with a hydrophilic layer may reduce urethral trauma and the incidence of urinary tract infections. However, extrapolation of the data is limited by lack of end-point standardization and heterogenous populations.

OBJECTIVE: To explore the data comparing single- vs multi-use catheters for clean intermittent catheterisation (CIC), consider if the widespread use of single-use catheters is warranted given the cost and environmental impact, and put forth ideas for future consideration.
METHODS: A primary literature review was performed in PubMed over the past 50 years. Studies that performed comparative analysis of single- and multi-use catheters were included in our review. All studies that reported on primary data were narratively summarised.
RESULTS: A total of 11 studies were identified that reported on primary data comparing single- and multi-use catheters. There was no appreciable evidence suggesting reusable multi-use catheters were inferior to single-use catheters from an infection or usability standpoint. In addition, the environmental and monetary burden of single-use catheters is significant.
CONCLUSIONS: The intermittent catheter landscape in the USA has a complex past: defined by policy, shaped by industry, yet characterised by a paucity of data demonstrating superiority of single-use over multi-use catheters. We believe that the aversion to reusable catheters by many patients and healthcare professionals is unwarranted, especially given the cost and environmental impact. Moving forward, better comparative data and more sustainable practices are needed.

OBJECTIVE: 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.

OBJECTIVE: To confirm the improved performance of the micro-hole zone catheter (MHZC) compared to a conventional eyelet catheter (CEC) in male users of clean intermittent catheterizations (CICs).
METHODS: Male self-catheterizing subjects, who used hydrophilic sleeved soft/flexible CIC as the only bladder emptying method, were enrolled into a multi-center, randomized, cross-over study performed across six European sites. Subjects tested the MHZC, featuring a drainage zone with 120 micro-holes and a CEC with two eyelets. The study consisted of four study visits (V0-V3), during which endpoints related to catheter performance (urinary flow-stops, bladder emptying, and intra-catheter pressure) were measured and two 4-week test periods at home (T1 and T2) where dipstick hematuria and user perception between catheters were evaluated.
RESULTS: Seventy-three male subjects with non-neurogenic and neurogenic bladder dysfunction (3:2) were enrolled. On average, catheterizations with the MHZC led to close to mean zero flow-stops compared to ≥1 flow-stops with the CEC, during both HCP- and self-led catheterizations (both p < 0.001). Residual urine at first flow-stop was significantly reduced for the MHZC compared to CEC (p = 0.001 and p = 0.004, for HCP- and self-led catheterizations, respectively). This was substantiated by a significantly smaller pressure peak at first flow-stop, a proxy for minimized mucosal suction (both HCP- and self-led catheterizations, p < 0.001). After home-use catheterizations, dipstick hematuria was comparable between catheters, whereas catheterizations were associated with significantly improved perception in favor of MHZC regarding bladder emptying, less blocking sensation, and improved hygienic catheterization compared to the CEC.
CONCLUSIONS: This study confirmed the evidence of improved bladder emptying with the MHZC compared to a CEC without the need to reposition the catheter. The MHZC therefore offers an enhanced benefit for the dependent CIC user securing complete bladder emptying in an uninterrupted free flow and reducing the need to reposition the catheter during emptying.

UNASSIGNED: Our aim was to evaluate trends and regional differences in the use of indwelling and intermittent urinary catheters in the community setting in the Netherlands from 2012 to 2021.
UNASSIGNED: For this population-based cohort study, data on catheter use was collected from the Drug and Medical Devices Information System of the National Healthcare Institute of the Netherlands. This database contains information on the Dutch insured population, which was 100% of the total population in 2018. Users were divided into 12 provinces according to the Nomenclature of Territorial Units for Statistics codes. The number of catheter users was adjusted for the total population of the provinces by sex and age, and was expressed by users per 100,000 people. Negative binomial regression (NBR) was used to test for differences in clean intermittent catheter (CIC) and indwelling catheter (IDC) users across Dutch provinces.
UNASSIGNED: Between 2012 and 2021, IDC users increased by 44.6% from 41,619 to 60,172, and CIC users increased by 27.3% from 34,204 to 43,528. The greatest increases were mainly observed among IDC users over 85 years old and male CIC users over 65 years old. NBR showed significant differences for IDC and CIC users between the 12 provinces. CIC incidence was higher in Drenthe and Groningen (Northern Netherlands) compared to Zuid-Holland (Southern Netherlands). IDC incidence was higher in seven provinces dispersed throughout the Netherlands compared to Noord-Holland.
UNASSIGNED: CIC and IDC users have continued to increase in recent years; this was especially observed among older men. In addition, there were regional differences in the number of CIC and IDC users; CIC was more prominent in the northern region of the Netherlands, and IDC varied between multiple provinces. Practice variation in urinary catheterization may result from patient population differences or healthcare provider preferences and their alignment with guidelines.

Urinomas are an accumulation of urine in the perirenal or paraureteral space due to urinary tract leakage. Stimulation of an inflammatory response results in the formation of a thick wall that encapsulates the urine. Etiologies of urinomas include trauma, surgery, or spontaneous occurrence. Complications when untreated vary and include peritonitis, fibrosis, abscess formation, and septic shock. We present a 52-year-old male with a neurogenic bladder who developed a rectus urinoma from the thorax to the scrotum. This likely developed from urethral trauma from intermittent self-catheterization. The patient received antibiotic therapy and percutaneous drainage catheters were placed in the rectus and pelvis, resolving the urinoma. We conclude that patients who perform intermittent self-catheterization may be more susceptible to formation of urinomas due to improper catheter usage. The intricate fascial connections between the pelvis and abdomen make proper interventions for suspected urinary tract injury crucial in patients who self-catheterize.

UNASSIGNED: Transient increases in postvoid residual urine volume (PVR) requiring clean intermittent catheterization (CIC) have occurred with onabotulinumtoxinA treatment for overactive bladder (OAB).
UNASSIGNED: To evaluate onabotulinumtoxinA safety and the effect of age, gender, and maximum PVR (PVRmax) on CIC initiation in adults with OAB and urinary incontinence (UI).
UNASSIGNED: This was a pooled post hoc analysis of four placebo-controlled, multicenter randomized trials that included adults with idiopathic OAB after first onabotulinumtoxinA treatment (NCT00910845, NCT00910520, NCT01767519, NCT01945489). Patients had at least three urgency UI episodes over 3 d and at least eight micturitions per day, had inadequate management with at least one anticholinergic agent, and were willing to use CIC.
UNASSIGNED: We measured the following outcomes: PVRmax within 12 wk after first treatment; CIC incidence; estimated functional capacity; PVR ratio (PVR/estimated functional capacity).
UNASSIGNED: Of 1504 patients, 87.7% were women and 88.8% were White. The mean age was 60.5 yr across 10-yr age groups, baseline PVR was 13.8-35.0 ml, and estimated functional capacity was 293.5-475.7 ml. Mean baseline PVR was 21.3 ml overall versus 34.0 ml in the group that started CIC. The CIC incidence was 6.2% for women (range 1.1-8.4%) and 10.5% for men (range 0-14.6%). Higher CIC rates were observed for PVRmax >350 ml (women 91.9%, men 84.6%) in comparison to PVRmax of 201-350 ml (women 32.5%, men 17.4%) and PVRmax <200 ml (women 1.2%, men 1.6%). Overall, 2/1504 patients (both women) were unable to void spontaneously. The mean PVR ratio was highest at week 2. Some subgroups had small sample sizes.
UNASSIGNED: CIC incidence was low overall, was less frequent for women, was rare with PVRmax ≤200 ml, and did not appear to correlate with baseline PVR.
UNASSIGNED: After onabotulinumtoxinA treatment for OAB, patients sometimes insert a catheter to help in emptying their bladder after urinating. In this study, few patients needed a catheter, especially when less urine volume remained after urination.

Treatment of urethral stricture is a complex reconstructive urology treatment. Previous surgery in the treatment of urethral stricture increases the risk of urinary incontinence. Therefore, this study aimed to assess the outcome of comparing two preservative or nonsurgical methods, clean intermittent catheterization (CIC) or hydraulic urethral dilatation (HUD). Forty-eight patients diagnosed with symptomatic urethral stricture were enrolled in the study. Patients were randomly divided into two groups: Nelaton-based dilatation and HUD treatment. Patients were assessed using patient-reported outcome measure for urethral stricture surgery (USS-PROM) through direct clinical interview and were followed up for 12 months. The rate of urinary infection, the need for surgical intervention, and the patient\'s quality of life were considered as outcomes of the interventions. SPSS software, version 20.0, was used for statistical analysis. Overall, 23 (47.9%) patients underwent HUD of stricture and Nelaton-based dilatation of stricture was done in 25 (52.1%) patients. We found that surgical intervention was required in four patients in the HUD group, but 15 patients in the CIC group required surgical intervention. Also, the need for surgical intervention and urinary tract infection (UTI) was significantly greater in the CIC group compared with the HUD group. With respect to the patient-reported outcomes, the mean Peeling\'s voiding picture (Q8) and EQ-VAS score (Q16) in the HUD group (p = .02) were significantly greater than those in the CIC group (p = .02). We obtained excellent results by using an HUD catheter. This safe, simple, well-tolerated, home-based procedure reduced the need for hospital admission to operate for repeat.

There is evidence that there is no difference in the incidence of urinary tract infections between multiple-use catheters that are cleaned after use and single-use catheters for intermittent catheterization. Despite the very significant economic and environmental advantages of multiple-use catheters, the single-use option is still promoted. The increasing focus on sustainability in urology may prompt a shift in practice to multiple-use catheters or other novel solutions in this setting. PATIENT SUMMARY: In intermittent catheterization, a patient or their caregiver periodically inserts a catheter to drain the bladder of urine. Single-use catheters are more expensive and have a greater impact on the environment than resuable catheters that are cleaned after use. To improve sustainability in health care, a switch from single-use to multiple-use catheters or other novel soultions for intermittent catheterization should be considered.
