Managing External Urinary Catheters

This narrative review explores the use of external urinary catheters. These devices are available in various types and materials for male and female patients. The indications for the use of external urinary catheters include managing incontinence linked to overactive bladder and neurogenic lower urinary tract dysfunction. Contraindications to the use of external urinary catheters include urinary obstruction. Proper skin care and proactive infection control measures are necessary to prevent complications. The collection of a urine specimen for culture requires a standardized technique to prevent contamination. Clinician-led patient education on catheter management plays a important role in ensuring patient comfort and safety.

Efficacy of expanded periurethral cleansing in reducing catheter-associated urinary tract infection in comatose patients: a randomized controlled clinical trial

BACKGROUND

The effect of the periurethral cleansing range on catheter-associated urinary tract infection (CAUTI) occurrence remains unknown. The purpose of this study was to evaluate the efficacy of expanded periurethral cleansing for reducing CAUTI in comatose patients.

METHODS

In this randomized controlled trial, eligible patients in our hospital were enrolled and allocated randomly to the experimental group (expanded periurethral cleansing protocol; n = 225) or the control group (usual periurethral cleansing protocol; n = 221). The incidence of CAUTI on days 3, 7, and 10 after catheter insertion were compared, and the pathogen results and influencing factors were analyzed.

RESULTS

The incidences of CAUTI in the experimental and control groups on days 3, 7, and 10 were (5/225, 2.22% vs. 7/221, 3.17%, P = 0.54), (12/225, 5.33% vs. 18/221, 8.14%, P = 0.24), and (23/225, 10.22% vs. 47/221, 21.27%, P = 0.001), respectively; Escherichia coli and Candida albicans were the most common species in the two groups. The incidences of bacterial CAUTI and fungal CAUTI in the two groups were 11/225, 4.89% vs. 24/221, 10.86%, P = 0.02) and (10/225, 4.44% vs. 14/221, 6.33%, P = 0.38), respectively. The incidences of polymicrobial CAUTI in the two groups were 2/225 (0.89%) and 9/221 (4.07%), respectively (P = 0.03). The percentages of CAUTI-positive females in the two groups were 9.85% (13/132) and 29.52% (31/105), respectively (P < 0.05). The proportion of CAUTI-positive patients with diabetes in the experimental and control groups was 17.72% (14/79), which was lower than the 40.85% (29/71) in the control group (P < 0.05).

CONCLUSION

Expanded periurethral cleansing could reduce the incidence of CAUTI, especially those caused by bacteria and multiple pathogens, in comatose patients with short-term catheterization (≤ 10 days). Female patients and patients with diabetes benefit more from the expanded periurethral cleansing protocol for reducing CAUTI.

Understanding the challenges faced by men learning to live with clean intermittent self-catheterisation

Clean intermittent self-catheterisation (CISC) is considered the preferred option to an indwelling catheter for emptying the bladder in people with a range of voiding dysfunctions. CISC has a lower risk of complications and urinary tract infections. This narrative review of previous qualitative research explores the quality-of-life impacts and highlights the challenges that men face. It will provide nurses who teach CISC with some useful insights into the male experience and the issues of concordance and adherence. This will help to better inform and guide clinical practice in this specialist area of nursing practice.

Catching Up With Clean Intermittent Catheterization: Guide to Products, Tips, and Tricks

Clean intermittent catheterization (CIC) is the gold standard for the management of urinary retention. Students with special healthcare needs who require CIC can be supported by school nurses who have knowledge and expertise in the management of CIC including an understanding of available products, reinforcement of proper technique, and resources available to promote student independence. This article will discuss the variety and unique features of CIC products and tips to overcoming barriers in bladder management.

Safety and efficacy of fluoroscopy-guided urethral catheterization in case of failed blind or cystoscopy-assisted urethral catheterization

This retrospective study evaluated the safety and efficacy of fluoroscopy-guided urethral catheterization in patients who failed blind or cystoscopy-assisted urethral catheterization. We utilized our institutional database between January 2011 and March 2023, and patients with failed blind or cystoscopy-assisted urethral catheterization and subsequent fluoroscopy-guided urethral catheterization were included. A 5-Fr catheter was inserted into the urethral orifice, and the retrograde urethrography (RGU) was acquired. Subsequently, the operator attempted to pass a hydrophilic guidewire to the urethra. If the guidewire and guiding catheter could be successfully passed into the bladder, but the urethral catheter failed pass due to urethral stricture, the operator determined either attempted again with a reduced catheter diameter or performed balloon dilation according to their preference. Finally, an appropriately sized urethral catheter was selected, and an endhole was created using an 18-gauge needle. The catheter was then inserted over the wire to position the tip in the bladder lumen and ballooned to secure it. We reviewed patients' medical histories, the presence of hematuria, and RGU to determine urethral abnormalities. Procedure-related data were assessed. Study enrolled a total of 179 fluoroscopy-guided urethral catheterizations from 149 patients (all males; mean age, 73.3 ± 13.3 years). A total of 225 urethral strictures were confirmed in 141 patients, while eight patients had no strictures. Urethral rupture was confirmed in 62 patients, and hematuria occurred in 34 patients after blind or cystoscopy-assisted urethral catheterization failed. Technical and clinical success rates were 100%, and procedure-related complications were observed in four patients (2.2%). The mean time from request to urethral catheter insertion was 129.7 ± 127.8 min. The mean total fluoroscopy time was 3.5 ± 2.5 min and the mean total DAP was 25.4 ± 25.1 Gy cm2. Balloon dilation was performed in 77 patients. Total procedure time was 9.2 ± 7.6 min, and the mean procedure time without balloon dilation was 7.1 ± 5.7 min. Fluoroscopy-guided urethral catheterization is a safe and efficient alternative in patients where blind or cystoscopy-assisted urethral catheterization has failed or when cystoscopy-urethral catheterization cannot be performed.

Comparison of digital and speculum-guided methods of transcervical Foley catheter insertion in primigravida undergoing cervical ripening at term gestation: a noninferiority randomized clinical trial

BACKGROUND

Foley catheter insertion is frequently used for cervical ripening during the induction of labor. However, the insertion failure, safety, maternal side effects, complications, and satisfaction of digital compared with speculum-guided Foley catheter placement have not been evaluated in a large trial involving primigravida.

OBJECTIVE

The study aimed to compare the insertion failure rate of digital and speculum-based transcervical Foley catheter placement in primigravida. The co-primary outcome was insertion-associated pain. The secondary outcomes were the time required for successful insertion, maternal satisfaction, and maternal complications within 24 hours of Foley insertion.

STUDY DESIGN

This randomized, open-label, parallel-arm, noninferiority clinical trial was performed in a large tertiary care university hospital. Primigravida aged >18 years with term gestation (≥37 weeks) were included in this study. Additional inclusion criteria for enrollment in this study were singleton pregnancy with a cephalic presentation, intact membrane, a Bishop score of ≤5, and reassuring preinduction fetal heart rate tracing. All women planned for cervical ripening were assessed for eligibility and were randomized into digital or speculum arms. Foley catheter insertion was performed in a supine lithotomy position. Vaginal and cervical cleaning were performed before insertion. A 22-French Foley balloon catheter was guided digitally or via speculum to position the bulb at the level of the internal os using water-soluble lubricant. Insertion-associated pain was measured using a visual numeric rating scale, and maternal satisfaction was assessed using a set of questions.

RESULTS

Four hundred and sixty-nine pregnant women were assessed for eligibility, and 446 patients were enrolled and randomized. The median age of the parturients was 24 (19-40) and 24 (18-38) years, respectively. The body mass index, gestational age at randomization, the incidence of postdated pregnancy, and prerandomization Bishop scores were comparable. Insertion failure was observed in 24 (10.8%) and 17 (7.6%) women in digital and speculum arms, respectively (relative risk=1.41 [95% confidence interval, 0.78-2.55]; P=.25). Requirements of >1 attempt (5.4% vs 3.6%) followed by the change in hands (3.6% vs 2.7%) were the most common reasons for insertion failure. The median (interquartile range) visual numeric rating scale was comparable (6 [2-9] vs 5 [2-10]; P=.15). The time taken for successful insertion was similar (58 [12-241] vs 54 [10-281]; P=.30). 9.4% and 10.8% of women required additional methods of cervical ripening. More women in the speculum group (41.7% vs 33.2%; P=.06) felt a medium level of discomfort than the digital group.

CONCLUSION

Insertion failure and insertion-related pain in the digital approach were comparable to the speculum-guided approach for transcervical Foley catheter insertion in primigravida for cervical ripening. Nevertheless, maternal satisfaction was higher in the digital group because of a lesser level of discomfort.

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.

Improved emptying performance with a new micro-hole zone catheter in adult male intermittent catheter users: A comparative multi-center randomized controlled cross-over study

AIMS

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.

CONCLUSION

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.

Reduction in catheter-associated urinary tract infections following a diagnostic stewardship intervention

Catheter-associated urinary tract infections (CAUTIs) are a frequent hospital-acquired infection and public health concern. In an attempt to reduce the number of CAUTIs, an intervention that emphasized the appropriate laboratory evaluation by ordering providers was implemented. This intervention supplemented ongoing standard bundle protocols. Compared to the 16 months before the intervention, there was a significant decrease in the number of CAUTIs during the 12-month intervention period.

Patient Removal of Urinary Catheters After Urogynecologic Surgery: A Randomized Controlled Trial

OBJECTIVE

To compare postoperative urinary retention rates in the early postoperative period between home and office catheter removal. Secondary outcomes included pain, difficulty, satisfaction, likelihood to use again, and health care utilization.

METHODS

We conducted a nonblinded, randomized controlled, noninferiority trial of women undergoing surgery for stress incontinence and prolapse from March 2021 to June 2022. Exclusion criteria were preoperative voiding dysfunction (need for self-catheterization or postvoid residual [PVR] greater than 150 mL), urethral bulking, and need for prolonged postoperative catheterization. Participants discharged with indwelling catheters because of an initial failed void trial were randomized 1:1 to home compared with office removal on postoperative day 3-4. For home removal, participants were instructed to remove the catheter at 7 am and to drink two glasses of water. If they had difficulty voiding 5 hours after catheter removal, they came to the office for a void trial. For office removal, participants returned for a backfill void trial with PVR assessment. Our primary outcome was rate of early postoperative urinary retention , defined as confirmed retention (PVR greater than half the voided volume) after catheter removal. Secondary outcomes were assessed at a 2-week call. Health care utilization (telephone calls and office visits) related to catheter issues was also assessed. At 80% power and α=0.05, we needed 100 participants (50/group) to detect a noninferiority margin of 11%.

RESULTS

Among 117 participants, the home (n=59) and office (n=58) removal groups were similar in mean age (60 years vs 61 years), mean body mass index (29 vs 30), pelvic organ prolapse quantification system stage 3 or 4, and proportion who underwent hysterectomy or apical suspension. Sling procedures were more common in the office group (45.8% vs 77.6%). For our primary outcome, the rate of early postoperative retention was 11.9% in the home group and 22.4% in the office group ( P =.13). Our predetermined noninferiority margin was greater than the upper bound of our 95% CI; thus, we conclude noninferiority of home removal. For secondary outcomes, the home removal group was more likely to report "no pain" ( P =.02) and "very likely" to use this method again ( P =.004). There were no differences in difficulty or satisfaction between groups. Number of nursing calls was not different ( P =.66); however, number of office visits was higher in the office group (median 0 [interquartile range 0-1] vs 1 [1-1], P <.001).

CONCLUSION

Postoperative urinary catheter removal by the patient at home was noninferior to office removal when early urinary retention rates were compared. Participants in the home removal group had fewer office visits and reported low pain, low difficulty, and high satisfaction.

Early Onset Clean Intermittent Catheterization May Decrease Prevalence and Severity of Urinary Concentration Defects in Myelomeningocele Patients with Neurogenic Bladder: A Retrospective Cohort Study

PURPOSE

Myelomeningocele is the most severe form of spina bifida. Management of urologic consequences of spina bifida is life long, demanding and costly for both the patient and the public health system. There is a paucity of data in the literature regarding concentration defects and their consequences on this disease. This paper aims to describe retrospectively the effect of early onset clean intermittent catheterization (CIC) in on the severity of urinary concentration defects in myelomeningocele patients with neurogenic bladder in a retrospective observational study.

MATERIALS AND METHODS

In this 10-year retrospective cohort study, children with myelomeningocele were selected with the Convenience sampling method. Demographic characteristics, polyuria index ratio (PIR) defined as 24 hour urine output of each patient divided by the maximum normal urine output of the same patient in a healthy state, and nocturnal polyuria index (NPI) were compared between early starters (< 2 years old) or late starters (≥ 2 years old) groups.

RESULTS

Seven patients who underwent cystoplasty were excluded and 130 patients (63.8% male, 5.4 ± 3.2 years old, 14.3 ± 2.83 Kg, 28.5% early onset CIC) were investigated. PIR > 1 in inset (1.7 ± 0.2 vs. 2.2 ± 0.5, P = 0.021) and outset (1.5 ± 0.32 vs. 2.5 ± 0.7, P = 0.004) were lower in early starters group than in late starters group. NPI in inset (0.2 ± 0.007 vs. 0.32 ± 0.10, P = 0.018) and outset (0.25 ± 0.15 vs. 0.42 ± 0.095, P = 0.007) were also lower in the early starters group. No further adverse events were reported during the follow-up period.

CONCLUSION

Early onset CIC is more effective than late-onset CIC in preserving the urinary ability of kidneys in myelomeningocele patients.

Effect of precision management scheme based on the best evidence summary on reducing catheter-associated urinary tract infection

OBJECTIVES

Catheter-associated urinary tract infection (CAUTI) is an important cause of prolonged hospital stay, which increases economic and medical burden for patients and hospitals, and it is a key focus of hospital infection prevention and control. However, there are currently few studies that convert evidence-based scientific evidence on CAUTI prevention and control into clinical applications and evaluation on its practical effects in combination with standardized infection ratio (SIR), the critical indicator of infection prevention and control. This study aims to establish a precision management plan for reducing the incidence of CAUTI, driven by the findings of a comprehensive evidence summary, to apply this plan across all the nursing units within the entire hospital, followed by a comparative analysis of CAUTI incidence, SIR, the average duration of indwelling urinary catheter for each patient, and the compliance rate on hand hygiene protocols for medical staff before and after the implementation of the precision management plan.

METHODS

Based on a comprehensive review of the best evidence for preventing CAUTI, a precision management plan was meticulously developed through panel discussions and 2 rounds of expert consultations using Delphi technique. Subsequently, a historical control study was conducted to evaluate the plan's effectiveness. A total of 17 658 patients with indwelling urinary catheter in inpatient departments from January to December 2021 comprised the control group. These patients received standard nursing measures for CAUTI. Another 18 753 patients with indwelling urinary catheters in the inpatient departments from January to December 2022 comprised the intervention group, underwent the precision management scheme based on the best available evidence, to enhance CAUTI prevention. The incidence and SIR of CAUTI, the average duration of indwelling urinary catheter for each patient, and the compliance rate on hand hygiene protocols for medical staff were compared between the 2 groups.

RESULTS

Compared with the control group, the incidence of CAUTI in the intervention group was significantly decreased (0.48‰ vs 1.12‰, χ2=20.814, P<0.001), SIR was decreased in the intervention group (0.55 vs 1.37); the average duration of indwelling urinary catheter for each patient was significantly decreased [(4.33±1.55) d vs (4.43±1.79) d, t=11.941, P<0.001]. The ratio of compliance rate of medical staff with strict hand hygiene protocols higher than 95% in the intervention group was significantly higher than that in the control group (93.3% vs 83.3%, χ2=5.822, P=0.016).

CONCLUSIONS

The implementation of the precision management plan for reducing CAUTI based on a summary of the best available evidence on CAUTI prevention and control in patients with indwelling urinary catheters has found to be effective. This approach significantly reduces the incidence of CAUTI, reduces the average duration of indwelling urinary catheter, and enhances hand hygiene compliance among medical staff. It provides a scientific and efficient strategy for preventing and controlling CAUTI in the hospital, ultimately saving patients from unnecessary medical expense.

Biomimetic urine flow control can preserve bladder function in patients with indwelling catheterization

For patients with long-term indwelling catheterization, bladder function will be affected. It is necessary to explore whether biomimetic urine flow control (BUFC) can improve bladder function in patients undergoing indwelling catheterization. A retrospective, data-only, cohort study was carried out. The patients admitted to the intensive care unit, who had retained catheter and been continuously using a urodynamic monitoring system for over 30 days were selected. They were divided into 2 groups based on whether they were using BUFC function. The urodynamic monitoring data of the 2 groups were compared and analyzed. A total of 30 patients were included in the final analysis, including 15 in the BUFC group and 15 in the unobstructed group. The Urinary Volume and maximal urinary flow rate of the unobstructed group showed a continuous downward trend, while the BUFC group remained stable, and there was a statistical difference (P < .05) between the 2 groups since day 20. The bladder ultrasound imaging showed that the bladder volume of the BUFC group did not decrease significantly on the 30th day. BUFC technology, which provided by a urodynamic monitoring system, has potential protective effects of the bladder function after indwelling catheterization.

Is Urethral Catheterization Necessary in Retzius-sparing Robot-assisted Radical Prostatectomy?

OBJECTIVE

To analyze whether urethral catheter (UC)-free anastomosis during Retzius-sparing radical prostatectomy (RP) results in worsening immediate perioperative and postoperative complications.

METHODS

We retrospectively reviewed records of patients undergoing robotic-assisted RP with or without indwelling UC placement by a single surgeon between January 2020 and March 2022. Clinical and pathological characteristics were evaluated. An independent t-test was used to compare continuous variables, and Pearson's chi-square test or Fisher exact test was used to compare categorical variables.

RESULTS

One hundred fifteen patients underwent robotic prostatectomy from January 2020 to June 2022. Sixty-two patients had both a UC for 12 hours postoperatively and a suprapubic catheter for 6days, while in 53 patients a UC was omitted. There was no significant difference noted between the groups regarding age, body mass index, American Society of Anesthesiology score, prostate-specific antigen, stage, node status, or positive margins. There were no significant differences in the rates of anastomotic leak, ileus, or urethral stricture. Patients had a significantly higher pad-free rate in the suprapubic catheter-only group (P = .04) at 3months. There was no difference in average number of pads used or the number using more than 1 pad/day.

CONCLUSION

Omission of urethral catheterization during Retzius-sparing RP is safe and doesn't result in an increased risk in perioperative or postoperative complications, but rather appears to be associated with a significantly improved 3-month pad-free rate.

Improved Performance With the Micro-Hole Zone Intermittent Catheter: A Combined Analysis of 3 Randomized Controlled Studies Comparing the New Catheter Technology With a Conventional Eyelet Catheter

PURPOSE

To assess the performance of a new urinary intermittent catheter (IC) prototype designed with a micro-hole drainage zone compared to a conventional eyelet catheter (CEC) in terms of flow-stop, bladder emptying, and hematuria.

DESIGN

Randomized controlled crossover studies.

SUBJECT AND SETTING

The sample comprised 15 male healthy volunteers (HV) and 15 IC users, along with 15 female HV and 15 IC users. The age range was lower for HV participants than for IC users (range: 20-57 years for HV vs 21-82 years for IC users). The study setting was the Department of Urology, located in Rigshospitalet, Copenhagen.

METHODS

Number of flow-stop incidents, residual urine volume at first flow-stop (RV1), and dipstick hematuria were measured during and after catheterization by a health care professional (HV) and by self-catheterisation (IC-users). Results from the 3 studies were combined for HV and IC users on RV1 and number of flow-stop incidents but separated on sex. For incidents of hematuria, an effect of underlying condition was assumed, and a combined analysis on sex was performed, separating HV and IC users.

RESULTS

When compared to the micro-hole drainage zone design, catheterizations with CEC resulted in a significantly higher mean RV1 (mean difference: 49 mL in males and 32 mL in females, both P < .001) and average number of flow-stop incidents (8 and 21 times more frequent for males and females, respectively, both P < .001). The likelihood for hematuria was 5.84 higher with CEC than with micro-hole drainage hole design, P = .053, during normal micturition in HV postcatheterization. No serious adverse events were reported.

CONCLUSION

The micro-hole drainage zone catheter provides IC users fewer premature flow-stops. This design feature reduces modifiable urinary tract infection risk factors, such as residual urine and micro-trauma; additional research is needed to determine its effects on bladder health.

Risk factors for urinary tract infections associated with lower quality of life among intermittent catheter users

BACKGROUND

Evidence shows that intermittent catheterisation (IC) for bladder emptying is linked to urinary tract infections (UTIs) and poor quality of life (QoL).

AIM

To investigate the association between UTI risk factors and QoL and patient-reported UTIs respectively.

METHODS

A survey was distributed to IC users from 13 countries.

FINDINGS

Among 3464 respondents, a significantly poorer QoL was observed when experiencing blood in the urine, residual urine, bowel dysfunction, recurrent UTIs, being female, and applying withdrawal techniques. A lower UTI risk was found when blood was not apparent in urine (RR: 0.63; 95% CI: 0.55-0.71), the bladder was perceived empty (RR: 0.83; 95% CI: 0.72-0.96), not having bowel dysfunction (RR: 0.86; 95% CI: 0.76-0.98), and being male (RR: 0.70; 95% CI: 0.62-0.79).

CONCLUSION

This study underlines the importance of risk factors and their link to QoL and UTIs, highlighting the need for addressing symptoms before UTIs become problematic.

[Intermittent catheterization: What are the environmental impacts and how can they be reduced?]

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.

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.

Assessment of patient satisfaction with home vs office indwelling catheter removal placed for urinary retention after female pelvic floor surgery: a randomized controlled trial

BACKGROUND

Postoperative urinary retention is burdensome for patients. We seek to improve patient satisfaction with the voiding trial process.

OBJECTIVE

This study aimed to assess patient satisfaction with location of indwelling catheter removal placed for urinary retention after urogynecologic surgery.

STUDY DESIGN

All adult women who were diagnosed with urinary retention requiring postoperative indwelling catheter insertion after undergoing surgery for urinary incontinence and/or pelvic organ prolapse were eligible for this randomized controlled study. They were randomly assigned to catheter removal at home or in the office. Those who were randomized to home removal were taught how to remove the catheter before discharge, and were discharged home with written instructions, a voiding hat, and 10-mL syringe. All patients had their catheter removed 2 to 4 days after discharge. Those patients who were allocated to home removal were contacted in the afternoon by the office nurse. Subjects who graded their force of urine stream 5, on a scale of 0 to 10, were considered to have safely passed their voiding trial. For patients randomized to the office removal group, the voiding trial consisted of retrograde filling the bladder to maximum they could tolerate up to 300 mL. Urinating >50% of instilled volume was considered successful. Those who were unsuccessful in either group had catheter reinsertion or self-catheterization training in the office. The primary study outcome was patient satisfaction, measured based on patients' response to a question, "How satisfied were you with the overall removal process of the catheter?" A visual analogue scale was created to assess patient satisfaction and 4 secondary outcomes. A sample size of 40 participants per group were needed to detect a 10 mm difference in satisfaction between groups on the visual analogue scale. This calculation provided 80% power and an alpha of 0.05. The final number accounted for 10% loss to follow up. We compared the baseline characteristics, including urodynamic parameters, relevant perioperative indices, and patient satisfaction between the groups.

RESULTS

Of the 78 women enrolled in the study, 38 (48.7%) removed their catheter at home and 40 (51.3%) had an office visit for catheter removal. Median and interquartile range for age, vaginal parity, and body mass index were 60 (49-72) years, 2 (2-3), and 28 (24-32) kg/m2, respectively, in the overall sample. Groups did not differ significantly in age, vaginal parity, body mass index, previous surgical history, or type of concomitant procedures. Patient satisfaction was comparable between the groups, with a median score (interquartile range) of 95 (87-100) in the home catheter removal group and 95 (80-98) in the office catheter removal group (P=.52). Voiding trial pass rate was similar between women who underwent home (83.8%) vs office (72.5%) catheter removal (P=.23). No participants in either group had to emergently come into the office or hospital due to inadequate voiding afterwards. Within 30 days post operatively, a lower proportion of women in the home catheter removal group (8.3%) had urinary tract infection, compared to patients in the office catheter removal group (26.3%) (P=.04).

CONCLUSION

In women with urinary retention after urogynecologic surgery, there is no difference in satisfaction concerning the location of indwelling catheter removal when comparing home and office.

Hygiene management of intermittent self-catheterization using reusable silicone catheters in people with spinal cord lesions: A cross-sectional Internet survey in Japan

OBJECTIVES

To investigate hygiene management and catheter maintenance of reusable silicone catheters for intermittent self-catheterization (ISC) in Japan and examine their relationship with symptomatic urinary tract infection (sUTI).

METHODS

We conducted a cross-sectional Internet survey of people performing ISC using reusable silicone catheters owing to spinal cord lesions in Japan. Hygiene management and catheter maintenance of reusable silicone catheters and the incidence and frequency of sUTI were evaluated. We also examined the significant risk factors for sUTI.

RESULTS

Of 136 respondents, 62 (46%), 41 (30%), and 58 (43%) washed hands with water, washed hands with soap, and cleaned or disinfected the urethral meatus every time or most of the time before ISC, respectively. No significant difference was observed in the incidence and frequency of sUTI between respondents who adhered to these procedures and those who did not. There were no significant differences in the incidence and frequency of sUTI in respondents who changed their catheters every month and in those who changed their preservation solution within 2 days compared with those who did not. In multivariate analysis, pain during ISC, inconvenience of indoor mobility, bowel management problems, and participants' feeling of never having received instruction on catheter replacement were significant risk factors for sUTI.

CONCLUSIONS

There are individual differences in hygiene management and catheter maintenance of reusable silicone catheters, but the influence of these differences on the incidence and frequency of sUTI is not clear. Pain during ISC, bowel management problems, and inadequate instruction on catheter maintenance procedures are factors associated with sUTI.

[Assessing the impact of bladder ultrasound on catheter-associated urinary tract infections and health-care costs: an observational pre-post study]

. Assessing the impact of bladder ultrasound on catheter-associated urinary tract infections and health-care costs: an observational pre-post study.

INTRODUCTION

The placement of a urinary catheter is a standard procedure, but it can cause discomfort, increase the risk of infections and costs. Pelvic ultrasound is a non-invasive assessment of the bladder and bladder catheter placement that can be performed by nurses.

AIM

To assess the appropriateness of urinary catheter placement using bladder ultrasound, to monitor urinary catheter-associated urinary tract infections and costs associated with catheter use.

METHODS

A single-centre pre-post observational study was conducted from September 2021 to August 2022 in patients aged >18 years requiring urinary monitoring; the first 6 months patients were assessed without the use of bladder ultrasound (control group), while the last 6 months with bladder ultrasound.

RESULTS

189 patients were included in the pre-ultrasound group and 175 patients in the post-ultrasound group; the demographic and clinical characteristics of the two groups were comparable. The rate of inappropriate catheterisation was 22.6% in the pre-group, whereas no inappropriate catheterisation was performed in the post-group. There was a 2.2% of absolute reduction in the rate of urinary tract infections (from 8.5% to 6.3%). Costs associated with the use of urinary catheters were reduced by 74.2% (from 173 to 44.8 euros).

CONCLUSIONS

Bladder ultrasound in clinical practice is feasible and reduced the inappropriate use of bladder catheters, reducing patient risks and healthcare costs.

Mechanical and morphological characterisation of porcine urethras for the assessment of paediatric urinary catheter safety

Paediatric urinary catheters are often necessary in critical care settings or to address congenital anomalies affecting the urogenital system. Iatrogenic injuries can occur during the placement of such catheters, highlighting the need for a safety device that can function in paediatric settings. Despite successful efforts to develop devices that improve the safety of adult urinary catheters, no such devices are available for use with paediatric catheters. This study investigates the potential for utilising a pressure-controlled safety mechanism to limit the trauma experienced by paediatric patients during inadvertent inflation of a urinary catheter anchoring balloon in the urethra. Firstly, we establish a paediatric model of the human urethra using porcine tissue by characterising the mechanical and morphological properties of porcine tissue at increasing postnatal timepoints (8, 12, 16 and 30 weeks). We identified that porcine urethras harvested from pigs at postnatal week 8 and 12 exhibit morphological properties (diameter and thickness) that are statistically distinct from adult porcine urethras (postnatal week 30). We therefore utilise urethra tissue from postnatal week 8 and 12 pigs as a model to evaluate a pressure-controlled approach to paediatric urinary catheter balloon inflation intended to limit tissue trauma during inadvertent inflation in the urethra. Our results show that limiting catheter system pressure to 150 kPa avoided trauma in all tissue samples. Conversely, all of the tissue samples that underwent traditional uncontrolled urinary catheter inflation experienced complete rupture. The findings of this study pave the way for the development of a safety device for use with paediatric catheters, thereby alleviating the burden of catastrophic trauma and life changing injuries in children due to a preventable iatrogenic urogenital event.

Pragmatic review of interventions to prevent catheter-associated urinary tract infections (CAUTIs) in adult inpatients

BACKGROUND

Urinary tract infections (UTIs) are one of the most common hospital-acquired complications. Insertion of a urinary catheter and the duration of catheterization are the main risk factors, with catheter-associated UTIs (CAUTIs) accounting for 70-80% of hospital-acquired UTIs. Guidance is available regarding the prevention of hospital-acquired CAUTIs; however, how best to operationalize this guidance remains a challenge.

AIM

To map and summarize the peer-reviewed literature on model-of-care interventions for the prevention of CAUTIs in adult inpatients.

METHODS

PubMed, CINAHL and SCOPUS were searched for articles that reported UTI, CAUTI or urinary catheter outcomes. Articles were screened systematically, data were extracted systematically, and interventions were classified by intervention type.

FINDINGS

This review included 70 articles. Interventions were classified as single component (N=19) or multi-component (N=51). Single component interventions included: daily rounds or activities (N=4), protocols and procedure changes (N=6), reminders and order sets (N=5), audit and feedback interventions (N=3), and education with simulation (N=1). Overall, daily catheter reviews and protocol and procedure changes demonstrated the most consistent effects on catheter and CAUTI outcomes. The components of multi-component interventions were categorized to map common elements and identify novel ideas.

CONCLUSION

A range of potential intervention options with evidence of a positive effect on catheter and CAUTI outcomes was identified. This is intended to provide a 'menu' of intervention options for local decision makers, enabling them to identify interventions that are relevant and feasible in their local setting.

Is It Really the Foley? A Systematic Review of Bladder Management and Infection Risk

Background

The belief that intermittent catheterization results in fewer infections than indwelling catheters is commonly expressed in the spinal cord injury literature. Some practice guidelines strongly recommend intermittent over indwelling catheterization due to concerns about infections and other complications. However, studies on this topic are of low quality. Guidelines from the Consortium for Spinal Cord Medicine suggest the data regarding infection risk are mixed, and they do not recommend one bladder management method over the other.

Objectives

To compare risk of bias in studies reporting higher rates of urinary tract infection (UTI) with indwelling catheters to studies that found equal rates of UTI between indwelling and intermittent catheterization, and to describe implications in clinical decision-making.

Methods

A systematic search of PubMed, CINAHL, Embase, and SCOPUS databases from January 1, 1980, to September 15, 2020, was conducted. Eligible studies compared symptomatic UTI rates between indwelling and intermittent catheterization. We used a risk of bias assessment tool to evaluate each study.

Results

Twenty-four studies were identified. Only three of these reported significantly higher UTI risk with indwelling catheters, and all three demonstrated a critical risk of bias. More than half of the studies reported differences in UTI risk of less than 20% between the two methods. Studies with larger (nonsignificant) differences favoring intermittent catheterization were more susceptible to bias from confounding.

Conclusion

The hypothesis that indwelling catheters cause more UTIs than intermittent catheterization is not supported by the scientific literature. Most studies failed to demonstrate a significant difference in UTI risk, and studies with nonsignificant trends favoring intermittent catheterization were more susceptible to bias from confounding. Perceived risk of infection should not influence a patient's choice of catheter type.

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.

Bladder Management With Chronic Indwelling Catheter is Associated with Elevated Mortality in Patients with Spinal Cord Injury

OBJECTIVE

To evaluate the impact of bladder management method, specifically chronic indwelling catheter (IndC), on survival in patients with spinal cord injury (SCI) in Spinal Cord Injury Model System database.

METHODS

Spinal Cord Injury Model System is a multicenter longitudinal database since 1970 with >40,000 patients with SCI. Adult patients (>18 at the time of injury) were screened. Patients who died within 1 year of injury and had 2 or more changes in method of bladder management, or reported normal volitional void were excluded. Outcome of interest was death from nonpulmonary, nonwound related sepsis (NPNWS). Left truncation cox regression method using age as the time-scale was used to calculate hazard ratios.

RESULTS

A total of 13,616 patients were included. Comparison was performed between "IndC" group (n = 4872; 36.1%) vs "Other" (n = 8744; 63.9%). After adjusting for age and change in bladder management method, "IndC" is associated with elevated NPNWS mortality (2.10; 95% confidence interval 1.72-2.56, P < .001). Multivariable analysis, adjusting for age at injury, gender, race, education, insurance status, etiology of SCI, injury level, neurologic impairment level, and change in bladder management method, showed IndC was associated with significantly higher risk of death from NPNWS compared to other methods of bladder management.

CONCLUSION

In a large cohort of SCI patients, bladder management with IndC is predictive of significantly propagated NPNWS related mortality compared to other methods of bladder management. While identifying IndC is an independent mortality risk factor, a better understanding of the underlying mechanisms could inform strategies to improve neurourological care and survival after SCI.

Mode of Anesthesia and Bladder Management Following Orthopaedic Surgery in Children With Cerebral Palsy: A System Level Analysis

BACKGROUND

Postoperative urinary retention (POUR) is a surgical complication more prevalent in children with neurodisability and associated with an increase length of hospitalization. Risk factors include pre-existing bladder dysfunction, type and duration of surgery, anesthesia medications, postoperative opioid pain management, and patient demographics. The purpose of this investigation was (1) to determine the frequency of POUR following hip/lower limb orthopaedic procedures in which epidural analgesia was used for pain management; (2) to explore factors influencing postoperative bladder management.

METHODS

A retrospective analysis of clinical data was performed in an orthopaedic specialty care health care system. A health outcomes network was queried for patients with a diagnoses of cerebral palsy (ICD-9/10 codes) who had one of 57 unique CPT procedure codes corresponding to hip osteotomies or tenotomies from 2011 to 2019. All surgical observations included in analysis required a discrete data element and the confirmation of a secondary proxy. The database was also queried for postoperative medications received and patient demographics of interest.

RESULTS

A total of 704 surgical procedures met inclusion criteria resulting in a patient population with a mean age of 11 years, 58% male, 53% Caucasian, and 55% classified as quadriplegia [51% Gross Motor Function Classification System (GMFCS) levels IV/V]. Three hundred and thirty-five procedures (48%) involved epidural anesthesia. Sixty-five patients required intermittent catheterization (9.2%) postoperatively following foley catheter removal, of which 23 (3.3%) required recatheterization. The rate of recatheterization was similar regardless of anesthesia mode; 1.8% for general and 1.4% for epidural and was associated with a greater number of pain medications. Epidural anesthesia resulted in significantly longer periods of catheterization. For the total group the time to urinary catheter removal differed significantly among cerebral palsy subtypes, GMFCS Level, race, and ethnicity. Factors identified as significant predictors of the length of catheterization were epidural analgesia, number of pain medications, and osteotomy.

CONCLUSIONS

The number of postoperative pain medications utilized was more predictive of POUR than the mode of analgesia delivery; however, epidural analgesia and the type of surgical procedure did significantly impact the length of catheterization.

Two methodologies of the rendezvous procedure to establish ureteral continuity from a delayed ureteral leak following pelvic surgery

BACKGROUND

Ureteral trauma recognized in the operating theater is managed, for the most part, at the same surgical procedure oftentimes with urologic consultation. A delayed urine leak presents unique problems in that direct access to the site of the leak is not possible except by a reoperative procedure.

METHODS

In patients who develop delayed urine leakage following cancer surgery, the leakage may be controlled by the collaborative efforts of a urologist and interventional radiologist. Success depends on placement of a nephroureteral stent by the rendezvous procedure.

RESULTS

The sequence of procedures to reestablish ureteral continuity following a delayed leak are important in the successful placement of a nephroureteral stent. In the first methodology, through a percutaneous nephrostomy, a guidewire is placed in the ureter and down to the ureteral defect. The guidewire is then recovered and advanced into the bladder using a ureteroscope and grasping forceps. A nephroureteral stent is placed over the guidewire to bridge the gap and stent the ureteral defect. In the second methodology, the urologist passed a guidewire into the distal ureter, out of the ureteral defect, and into the free peritoneal space. Under fluoroscopic control, the wire loop must snare the ureteral guidewire and pull it out at the percutaneous nephrostomy. The nephroureteral stent is passed over the ureteral wire into the bladder.

CONCLUSIONS

Two different methodologies were described to complete the rendezvous procedure. It can be successful a large percentage of the time with a delayed ureteral leakage. Success requires a combined interventional radiology and urologic procedure.

Indwelling Urinary Catheter and Dementia Are Associated with Enterococcal Urinary Tract Infections in Hospitalized Patients

BACKGROUND

The recent increase in enterococcal urinary tract infections (EUTI) and the potential morbidity and mortality associated with inappropriate antimicrobial treatment underscores the need for early risk assessment and institution of appropriate empirical antimicrobial therapy.

OBJECTIVES

To identify high-risk features associated with hospitalized patients with EUTI.

METHODS

Demographic, clinical, laboratory, and bacteriological data of 285 patients hospitalized with UTI during 2016 were retrieved from the computerized database of Shamir Medical Center. Patients were divided into two groups: EUTI and non-EUTI (NEUTI), according to the presence or absence of enterococcus in the urine culture. The features of the two groups were compared.

RESULTS

We obtained 300 urine cultures from 285 patients. Of the total, 80 patients (26.6%) had EUTI and 220 patients (73.3%) had NEUTI. A higher prevalence of urinary multi-bacterial cultures was found in EUTI compared to NEUTI patients (P < 0.01). Higher prevalence of permanent indwelling urinary catheter and dementia were found in hospitalized patients with community-acquired EUTI and nosocomial EUTI respectively (P = 0.02, P = 0.016) compared to patients with NEUTI.

CONCLUSIONS

Indwelling urinary catheter and dementia are risk factors for EUTI in patients with community and hospital acquired infection, respectively.

Maternal and neonatal outcomes of pregnancies complicated by late fetal growth restriction undergoing induction of labor with dinoprostone compared with cervical balloon: A retrospective, international study

INTRODUCTION

The aim of this study was to compare vaginal dinoprostone and mechanical methods for induction of labor (IOL) in pregnancies complicated by late fetal growth restriction.

MATERIAL AND METHODS

Multicenter, retrospective, cohort study involving six referral centers in Italy and Spain. Inclusion criteria were pregnancies complicated by late fetal growth restriction as defined by Delphi consensus criteria. The primary outcome was the occurrence of uterine tachysystole; secondary outcomes were either cesarean delivery or operative vaginal delivery for non-reassuring fetal status, a composite score of adverse neonatal outcome and admission to neonatal intensive care unit (NICU). Univariate and multivariate logistic regression analysis was used to analyze the data.

RESULTS

A total of 571 pregnancies complicated by late fetal growth restriction undergoing IOL (391 with dinoprostone and 180 with mechanical methods) were included in the analysis. The incidence of uterine tachysystole (19.2% vs. 5.6%; p = 0.001) was higher in women undergoing IOL with dinoprostone than in those undergoing IOL with mechanical methods. Similarly, the incidence of cesarean delivery or operative delivery for non-reassuring fetal status (25.6% vs. 17.2%; p = 0.027), composite adverse neonatal outcome (26.1% vs. 16.7%; p = 0.013) and NICU admission (16.9% vs. 5.6%; p < 0.001) was higher in women undergoing IOL with dinoprostone than in those undergoing IOL with mechanical methods. At logistic regression analysis, IOL with mechanical methods was associated with a significantly lower risk of uterine tachysystole (odds ratio 0.26, 95% confidence interval 0.13-0.54; p < 0.001).

CONCLUSIONS

In pregnancies complicated by late fetal growth restriction, IOL with mechanical methods is associated with a lower risk of uterine tachysystole, cesarean delivery or operative delivery for non-reassuring fetal status, and adverse neonatal outcome compared with pharmacological methods.

The efficacy of amniotic membrane-mediated sequential double-barrier therapy for the treatment of postoperative intrauterine adhesions

To study the efficacy of using amniotic membrane, balloon and intrauterine device (IUD) as barrier therapy to prevent re-adhesion after hysteroscopic adhesiolysis.A total of 45 patients diagnosed with intrauterine adhesions in Changzhou Maternal and Child Health Hospital from June 2014 to December 2017 were included in this retrospective case control study. According to different postoperative isolation barrier methods, the patients were divided into group A (Foley balloon + fresh amniotic membrane Day1 + IUD Day7) (22 cases) and group B (Foley balloon Day1 + IUD Day7) (23 cases). Three months after the surgery, the second hysteroscopy was performed to observe the condition of the uterine cavity and the improvement of menstruation, and to monitor the thickness of the endometrium.The efficacy of hysteroscopic procedure in group A was significantly higher than that of group B (P < .05). After 3 months of treatment, the improvement rate of menstruation was significantly higher in group A than in group B (P < .05). Endometrial thickness in both group A and B was significantly increased compared with that before the surgery (P < .05). The postoperative endometrium of group A was significantly thicker than that of group B (P < .05).Amniotic membrane-mediated sequential double-barrier method is clinically feasible for preventing recurrent intrauterine adhesions.

Postoperative interventions for preventing bladder dysfunction after radical hysterectomy in women with early-stage cervical cancer

BACKGROUND

Bladder dysfunction is a common complication following radical hysterectomy, caused by the damage to pelvic autonomic nerves that innervate the muscles of the bladder, urethral sphincter, and pelvic floor fasciae. Bladder dysfunction increases the rates of urinary tract infection, hospital visits or admission, and patient dissatisfaction. In addition, bladder dysfunction can also negatively impact patient quality of life (QoL). Several postoperative interventions have been proposed to prevent bladder dysfunction following radical hysterectomy. To our knowledge, there has been no systematic review evaluating the effectiveness and safety of these interventions for preventing bladder dysfunction following radical hysterectomy in women with cervical cancer.

OBJECTIVES

To evaluate the effectiveness and safety of postoperative interventions for preventing bladder dysfunction following radical hysterectomy in women with early-stage cervical cancer (stage IA2 to IIA2).

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2020, Issue 4) in the Cochrane Library, MEDLINE via Ovid (1946 to April week 2, 2020), and Embase via Ovid (1980 to 2020, week 16). We also checked registers of clinical trials, grey literature, conference reports, and citation lists of included studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) evaluating the effectiveness and safety of any type of postoperative interventions for preventing bladder dysfunction following a radical hysterectomy in women with stage IA2 to IIA2 cervical cancer.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected potentially relevant RCTs, extracted data, assessed risk of bias, compared results, and made judgments on the quality and certainty of the evidence. We resolved any disagreements through discussion or consultation with a third review author. Outcomes of interest consisted of spontaneous voiding recovery one week after the operation, quality of life (QoL), adverse events, post-void residual urine volume one month after the operation, urinary tract infection over the one month following the operation, and subjective urinary symptoms.

MAIN RESULTS

We identified 1464 records as a result of the search (excluding duplicates). Of the 20 records that potentially met the review criteria, we included five reports of four studies. Most of the studies had unclear risks of selection and reporting biases. Of the four studies, one compared bethanechol versus placebo and three studies compared suprapubic catheterisation with intermittent self-catheterisation. We identified two ongoing studies. Bethanechol versus placebo The study reported no information on the rate of spontaneous voiding recovery at one week following the operation, QoL, adverse events, urinary tract infection in the first month after surgery, and subjective urinary symptoms for this comparison. The volume of post-void residual urine, assessed at one month after surgery, among women receiving bethanechol was lower than those in the placebo group (mean difference (MD) -37.4 mL, 95% confidence interval (CI) -60.35 to -14.45; one study, 39 participants; very-low certainty evidence). Suprapubic catheterisation versus intermittent self-catheterisation The studies reported no information on the rate of spontaneous voiding recovery at one week and post-void residual urine volume at one month following the operation for this comparison. There was no difference in risks of acute complication (risk ratio (RR) 0.77, 95% CI 0.24 to 2.49; one study, 71 participants; very low certainty evidence) and urinary tract infections during the first month after surgery (RR 0.77, 95% CI 0.53 to 1.13; two studies, 95 participants; very- low certainty evidence) between participants who underwent suprapubic catheterisation and those who underwent intermittent self-catheterisation. Available data were insufficient to calculate the relative measures of the effect of interventions on QoL and subjective urinary symptoms.

AUTHORS' CONCLUSIONS

None of the included studies reported rate of spontaneous voiding recovery one week after surgery, time to a post-void residual volume of urine of 50 mL or less, or post-void residual urine volume at 6 and 12 months after surgery, all of which are important outcomes for assessing postoperative bladder dysfunction. Limited evidence suggested that bethanechol may minimise the risk of bladder dysfunction after radical hysterectomy by lowering post-void residual urine volume. The certainty of this evidence, however, was very low. The effectiveness of different types of postoperative urinary catheterisation (suprapubic and intermittent self-catheterisation) remain unproven.

Effects of Chlorpheniramine Maleate on Catheter-Related Bladder Discomfort in Patients Undergoing Ureteroscopic Stone Removal: A Randomized Double-Blind Study

Catheter-related bladder discomfort (CRBD) associated with intraoperative urinary catheterization is a distressing symptom during recovery from anesthesia. Anticholinergics have been used to manage CRBD. Chlorpheniramine maleate (CPM) is a first-generation antihistamine, which also has anticholinergic effects. This study was undertaken to evaluate the efficacy of CPM in preventing CRBD. Seventy-six adults (19-65 years old) with American Society of Anesthesiologists physical status I, II, or III of either sex, undergoing elective ureteroscopic stone removal under general anesthesia were randomized into one of two groups (each n = 38). Group C (control) received a placebo, and group CPM received 8 mg of intravenous CPM before the induction of anesthesia. CRBD was assessed upon arrival in the post-anesthetic care unit at 0, 1, 2, and 6 h. The severity of CRBD was graded as none, mild, moderate, and severe. Tramadol was administered when the severity of CRBD was more than moderate. The incidence rate and overall severity of CRBD did not differ between the groups at any of the time points (р > 0.05). The incidence of moderate CRBD was higher in group C than in group CPM only at 0 h (26.3% vs. 5.3%, р = 0.025). However, fewer patients in the CPM group required rescue tramadol to relieve CRBD after surgery (31.6% vs. 60.5%, р = 0.011). CPM administration before the induction of anesthesia had little effect on the incidence and severity of CRBD after surgery, but it reduced the administration of tramadol required to control CRBD postoperatively.

Urethroplasty with balloon catheterization in fetal lower urinary tract obstruction: observational study of 10 fetuses

OBJECTIVE

To present the preliminary outcomes of fetal urethroplasty using a coronary angioplasty balloon catheter in lower urinary tract obstruction (LUTO).

METHODS

We included 10 consecutive male fetuses diagnosed with LUTO caused by presumed isolated posterior urethral valves (PUVs), who underwent urethroplasty with a balloon catheter in our center between 2015 and 2018. During urethroplasty, the fetal urethra was dilated using a balloon catheter (diameter, 0.014 inches; balloon size, 2 × 9 mm) inserted under ultrasonographic guidance via an 18-gauge needle introduced into the fetal bladder.

RESULTS

Mean gestational age at the time of urethroplasty was 17.8 (range, 16.5-20.4) weeks. All fetuses survived the procedure without any complications and there was no case of preterm prelabor rupture of the membranes. The procedure was successful in 5/10 (50%) fetuses, while in the other five (50%), we were unable to insert the balloon catheter into the urethra. In the five successfully treated cases, mean gestational age at delivery was 38 (range, 36-40) weeks and presence of PUVs was confirmed after birth. All five neonates micturated spontaneously and presented with normal urine output after birth. During the follow-up period, the parameters of kidney function were within normal limits in two neonates, whereas signs of impaired renal function were seen in another two. The other was diagnosed with renal insufficiency and required kidney transplant with bladder sparing at 2 years of age.

CONCLUSIONS

Urethroplasty with a balloon catheter is a new prenatal treatment option for fetuses with PUVs. By restoring fetal micturition, the procedure can preserve normal urinary bladder and kidney function. Although data on its efficacy and potential to differentiate the etiology of LUTO are sparse, a significant advantage of this method is its safety for the fetus and the mother. Even if the neonates develop renal insufficiency, they may be eligible for kidney transplant with connection to their own bladder, without the need for urostomy. Copyright © 2019 ISUOG.

A simple novel training model for teaching suprapubic catheter (SPC) exchange

OBJECTIVES

To develop a suprapubic catheter (SPC) training model as no specific realistic training model exists to replicate SPC exchange where a catheter tract is present.

MATERIALS AND METHODS

We describe a novel, anatomically realistic, animal simulator model for use in SPC training, which was trialed at a national urology simulation boot camp by new urology trainees and validated by expert urologists. A scale reproduction of an abdominal wall was created using a porcine abdominal wall. A segment of small bowel was stitched around a size 16F Foley catheter to form a tract. Abdominal wall tissue was excised cylindrically to create an opening, and the small bowel tract was passed through the abdominal wall and sutured anteriorly, producing a realistic SPC tract: inferiorly, the tract was anastomosed to a porcine urinary bladder. This model was evaluated by 10 expert urologists for content validity with an 8-item 5-point rating scale used to evaluate domains relevant to the simulator.

RESULTS

The domains were scored between 1 and 5 by 10 expert urologists, 1 being «strongly disagree» and 5 being «strongly agree». The average expert ratings of the domains were then calculated and tabulated following the training course. There was an average global rating of 4.2/5 for the model, with an average usefulness for training score of 4.6/5.

CONCLUSION

The feedback from experts and trainees (informal) was overwhelmingly positive. On average, our experts reported high satisfaction with their experience using this simulator as a training tool.

The evidence supporting single-use intermittent catheters in people with spinal cord injury

Intermittent catheterization (IMC) is the accepted evidence-based best practice for bladder management in people with voiding dysfunction due to neurogenic bladder. The two methods for performing IMC over the decades since this practice was introduced are reuse and single-use catheters. There are perceived advantages and disadvantages of each method of performing IMC. There is considerable evidence that single-use IMC is associated with better health outcomes, including reduced risk of urinary tract infection, urethral trauma, and quality of life. People performing IMC also indicate a preference for single-use, although there are advantages of reuse that need to be acknowledged. Ideally, further research is needed in this area, particularly around the washing and storage of reuse catheters, as well as an adequately powered multicenter RCT comparing reuse with single-use IMC, but there are numerous challenges associated with progressing this research.

Role of noble metal-coated catheters for short-term urinary catheterization of adults: a meta-analysis

OBJECTIVE

To evaluate the efficacy of noble-metal coated catheters in reducing catheter-associated urinary tract infections (CAUTI) in adult patients requiring short term catheterization.

METHODS

An electronic literature search of PubMed, BioMed Central, Embase, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials) and Google scholar was carried out from inception to 10th October 2019. Any prospective study or randomized controlled trial (RCT) on adult patients comparing noble-metal coated urinary catheters with any standard catheter and evaluating the incidence of CAUTI or bacteriuria was included.

RESULTS

A total of 13 studies were included in the systematic review. 12 were RCTs and one was a prospective cross-over trial. Catheters employed in the study group were grouped into two sub-groups: Silver alloy coated or Noble metal alloy-coated (Gold, Silver, and Palladium) catheters. Bacteriuria was the most commonly studied outcome variable across trials. Meta-analysis indicated that silver alloy-coated catheters (RR 0.63, 95%CI 0.44-0.90, P = 0.01; I2 = 72%) and noble metal alloy catheters (RR 0.58, 95%CI 0.41-0.81, P = 0.001; I2 = 0%) significantly reduce the risk of bacteriuria. Sub-group analysis based on the duration of catheterization demonstrated that silver alloy catheters reduce the risk of bacteriuria with >1week of catheterization (RR 0.46, 95%CI 0.26-0.81, P = 0.007; I2 = 63%). Symptomatic CAUTI was evaluated only in four studies with variable results. The quality of the included studies was not high.

CONCLUSIONS

Our review indicates that bacteriuria may be reduced with the use of noble metal-coated catheters during short-term catheterization of adults, however, the quality of evidence is not high. It is not clear if these catheters reduce the risk of symptomatic CAUTI. Further homogenous RCTs are needed to provide clarity.

Considerations for Bedside Urologic Procedures in Patients With Severe Acute Respiratory Syndrome Coronavirus-2

Objective

To provide guidance when performing bedside urologic procedures on severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) positive patients and offer considerations to maximize the safety of the patients and providers, conserve supplies, and provide optimal management of urologic issues.

Methods

Urologic trainees and attending physicians at our institution, who are familiar with existing safety recommendations and guidelines regarding the care of infected patients, were queried regarding their experiences to determine an expert consensus on best practices for bedside procedures for SARS-CoV-2 positive patients.

Results

Our team developed the following general recommendations for urologic interventions on SARS-CoV-2 positive patients: maximize use of telehealth (even for inpatient consults), minimize in-room time, use personal protective equipment appropriately, enlist a colleague to assist, and acquire all supplies that may be needed and maintain them outside the room. Detailed recommendations were also developed for difficult urethral catheterization, bedside cystoscopy, incision and drainage of abscesses, and gross hematuria/clot irrigations.

Conclusion

As patients hospitalized with SARS-CoV-2 infection are predominantly men over 50 years old, there are significant urologic challenges common in this population that have emerged with this pandemic. While there is tremendous variation in how different regions have been affected, the demographics of SARS-CoV-2 mean that urologists will continue to have a unique role in helping to manage these patients. Here, we summarize recommendations for bedside urologic interventions specific to SARS-CoV-2 positive patients based on experiences from a large metropolitan hospital system. Regulations and requirements may differ on an institutional basis, so these guidelines are intended to augment specific local protocols.

Postoperative Complications After Colorectal Surgery: Where Are We in the Era of Enhanced Recovery?

PURPOSE OF REVIEW

Individual elements in enhanced recovery pathways may be associated with specific complication risks. In this review, we highlight three areas of controversy surrounding complications in enhanced recovery: (1) whether enhanced recovery is associated with increased rates of acute kidney injury, (2) whether NSAID use is associated with anastomotic leaks, and (3) whether early urinary catheter removal is justified following colorectal surgery.

RECENT FINDINGS

Acute kidney injury has been reported at several institutions following implementation of enhanced recovery pathways highlighting the importance of institutional data tracking. NSAID use has been implicated in anastomotic leak rates for non-elective colorectal procedures, and criteria for its use should be implemented. Early urinary catheter removal has been supported despite increased urinary retention rates in order to decrease urinary tract infections. Enhanced recovery protocols will continue to evolve, and risk profiles associated with individual elements should continue to be evaluated.

Cervical ripening: Why we do what we do

More than 20% of pregnant women have their labor induced and at least half of them will require cervical ripening due to an unfavorable starting cervical exam. The use of cervical ripening methods has been shown to decrease the risk of cesarean delivery when compared to initiating an induction with oxytocin in women with an unfavorable cervix. However, among the different cervical ripening methods themselves, while there may be differences in time to delivery and differences in the safety profile of different cervical ripening methods, there is no clear evidence that any one cervical ripening method reduces the risk of cesarean compared to another method. The objectives of this manuscript are to discuss the pathophysiology of cervical ripening including the biochemical processes that lead to cervical ripening; to review the different methods of cervical ripening including both mechanical and pharmacologic methods, and to evaluate the evidence and efficacy for different doses, routes, and techniques employed when using various cervical ripening methods.

Inadvertent Antegrade Urethral Placement of a Suprapubic Catheter

Presentation A 55-year-old male patient with neuropathic bladder secondary to multiple sclerosis (MS) presented to the EmergencyDepartment (ED) with abdominal pain and no output from his suprapubic catheter (SPC) that was changed 24 hourspreviously. Diagnosis On examination, the SPC-tip was clearly visible at the external urethral meatus. Treatment The patient was managed by gently deflating the anchoring balloon, exchanging the SPC and a period of observationto ensure adequate catheter drainage. Conclusion Important learning points from this case are to observe urine draining after routine SPC change and to examine thegenitalia when a misplaced SPC is suspected.

Catheter management after benign transurethral prostate surgery: RAND/UCLA Appropriateness Criteria

OBJECTIVES

To formally assess the appropriateness of different timings of urethral catheter removal after transurethral prostate resection or ablation. Although urethral catheter placement is routine after this common treatment for benign prostatic hyperplasia (BPH), no guidelines inform duration of catheter use.

STUDY DESIGN

RAND/UCLA Appropriateness Methodology.

METHODS

Using a standardized, multiround rating process (ie, the RAND/UCLA Appropriateness Methodology), an 11-member multidisciplinary panel reviewed a literature summary and rated clinical scenarios for urethral catheter duration after transurethral prostate surgery for BPH as appropriate (ie, benefits outweigh risks), inappropriate, or of uncertain appropriateness. We examined appropriateness across 4 clinical scenarios (no preexisting catheter, preexisting catheter [including intermittent], difficult catheter placement, significant perforation) and 5 durations (postoperative day [POD] 0, 1, 2, 3-6, or ≥7).

RESULTS

Urethral catheter removal and first trial of void on POD 1 was rated appropriate for all scenarios except clinically significant perforations. In this case, waiting until POD 3 was deemed the earliest appropriate timing. Waiting 3 or more days to remove the catheter for patients with or without preexisting catheter needs, or for those with difficult catheter placement in the operating room, was rated as inappropriate.

CONCLUSIONS

We defined clinically relevant guidance statements for the appropriateness of urethral catheter duration after transurethral prostate surgery. Given the lack of guidelines and this robust expert panel approach, these ratings may help clinicians and healthcare systems improve the consistency and quality of care for patients undergoing transurethral surgery for BPH.

Change in staff perspectives on indwelling urinary catheter use after implementation of an intervention bundle in seven Swiss acute care hospitals: results of a before/after survey study

OBJECTIVE

To evaluate changes in staff perspectives towards indwelling urinary catheter (IUC) use after implementation of a 1-year quality improvement project.

DESIGN

Repeated cross-sectional survey at baseline (October 2016) and 12-month follow-up (October 2017).

SETTING

Seven acute care hospitals in Switzerland.

PARTICIPANTS

The survey was targeted at all nursing and medical staff members working at the participating hospitals at the time of survey distribution. A total of 1579 staff members participated in the baseline survey (T₀) (49% response rate) and 1527 participated in the follow-up survey (T₁) (47% response rate).

INTERVENTION

A multimodal intervention bundle, consisting of an evidence-based indication list, daily re-evaluation of ongoing catheter need and staff training, was implemented over the course of 9 months.

MAIN OUTCOME MEASURES

Staff knowledge (15 items), perception of current practices and culture (scale 1-7), self-reported responsibilities (multiple-response question) and determinants of behaviour (scale 1-7) before and after implementation of the intervention bundle.

RESULTS

The mean number of correctly answered knowledge questions increased significantly between the two survey periods (T₀: 10.4, T₁: 11.0; p<0.001). Self-reported responsibilities with regard to IUC management by nurses and physicians changed only slightly over time. Perception of current practices and culture in regard to safe urinary catheter use increased significantly (T₀: 5.3, T₁: 5.5; p<0.001). Significant changes were also observed for determinants of behaviour (T₀: 5.3, T₁: 5.6; p<0.001).

CONCLUSION

We found small but significant changes in staff perceptions after implementation of an evidence-based intervention bundle. Efforts now need to be targeted at sustaining and reinforcing these changes, so that restrictive use of IUCs becomes an integral part of the hospital culture.
