Reusable Intermittent Catheters are Acceptable but Product Innovation is Needed: An Interview Study of Catheter Users' Experiences.

The purpose of this study was to explore the experiences of intermittent catheter users after using both reusable and single-use catheters, with a particular focus on factors that affected acceptability. Qualitative descriptive study following a clinical trial. Thirty-six participants who had used both reusable and single-use catheters in a clinical trial were interviewed between June 2022 and March 2024. All were living at home in England or Wales, UK. Participants were invited to interview following one-year's use of a reusable catheter as part of a clinical trial. The reusable catheter was used in combination with their usual single-use catheter. Semi-structured telephone and video interviews were used to enable participants to describe their experiences. Data were analyzed using inductive methods and framework analysis to develop themes and subthemes. Data analysis identified 4 themes. Successful use of the reusable catheter depended on capacity, confidence and willingness of the individual to adapt. Most people found reuse easier to do at home but there were significant barriers when going out. The design of the catheter used in the trial and the process of reuse did not suit everyone. While there was a desire to continue reuse, this was conditional on the provision of single-use catheters to enable users to mix and match both types in different situations. This study presents data from participants who were enthusiastic to try reusable catheters, mainly for environmental reasons, as part of a trial. For most there was a desire to mix and match, combining single use and reusable catheters for different situations. Innovation is needed to create a range of reusable catheter designs and cleaning processes that better meet individual needs.

Creating an Ellipsys percutaneous arteriovenous fistula after a failed ipsilateral WavelinQ fistula: A case report of an endovascular approach for access restoration.

The introduction of devices for endovascular dialysis access creation (WavelinQ and Ellipsys) offers practitioners more options for access management in dialysis patients. Especially in terms of reducing the usage of central venous catheters, a native fistula is desirable as an initial dialysis access. We present a case in which a failed WavelinQ type fistula was reactivated using the Ellipsys procedure on the same arm. This specific rescue method is based on the idea that the proximal part of an endoAVF from an earlier WavelinQ procedure which resulted in adequately dilated veins, comprising the perforating vein, may allow a subsequent Ellipsys procedure. This case report shows how the use of endovascular techniques such as WavelinQ and Ellipsys can be incorporated in a clinical context and create new options for the patient.

Literature Review : Prevalensi Jumlah Leukosit Pada Sampel Urine Pasien dengan Pemasangan Kateter

The use of urinary catheters is very common in hospitals. Urinary catheters are the most common cause of bacteriuria. Urinary tract infections are the cause of more than 1/3 of all hospital-acquired infections. Most of these infections (at least 80%) are caused by invasive procedures or urinary tract instrumentation, usually in the form of catheterization. Urine sediment examination aims to detect and identify insoluble materials in urine. The purpose of this study was to determine the prevalence of leukocyte counts in patients with catheter placement based on a literature review and to analyze the number of leukocytes in patients with catheter users based on a literature review. The method used was Systematic Literature Review (SLR). The results of this study obtained the results of the number of samples based on gender in women as many as 223 people and in men 147 people, with a total number of patients as many as 370. then the results of the number of samples based on patient age, the number of patients who were most catheterized at the age of 56-65 as many as 101 patients (27.0%), followed by age 46-55 as many as 96 patients (25.0%), age 36-45 as many as 68 patients (18.0%), age 26-35 as many as 39 patients (10.0%), age 17-25 as many as 30 patients (8.0%), and age> 65 as many as 36 patients (9.0%) with a total of 370 patients. The results of the study can be concluded that catheter installation can cause urinary tract infections.

Poor mid-term functional patency and post-operative outcomes in diabetic patients who undergo arteriovenous graft creation.

Diabetes mellitus is a leading cause of renal failure in the US and has been associated with higher mortality when compared to nondiabetic patients. This remains true despite initiation of renal replacement therapy. As such, we were interested in identifying any potential differences in access durability and postoperative outcomes in diabetic patients who receive arteriovenous fistulas versus grafts for hemodialysis. Diabetic patients undergoing their first arteriovenous (AV) access creation surgery in the Vascular Quality Initiative from January 2011 to January 2022 were included in our study. After exclusions, the study included two groups: those receiving AV fistulas and those receiving AV grafts for hemodialysis. Demographic characteristics were summarized and compared between these two groups using chi-square analysis or unpaired t-test. After propensity score matching was conducted, the effect of procedure type on functional patency, along with secondary outcomes including wound infection were assessed using chi-square analysis. A total of 20,159 diabetic patients who used their hemodialysis access were included in our study; 16,205 received AV fistulas while 3954 received AV grafts. Patients receiving AV grafts were more likely to be older, female, and have higher pre-operative catheter usage. After propensity score matching, patients who received AV grafts had a shorter time-to-use their conduit (50 vs 166 days, p < 0.0001), however, patients who received AV fistulas were more likely to have longer functional patency use for hemodialysis when compared to those who received AV grafts (mean survival time: 3.3 vs 2.9 years, p < 0.0001). These results were consistent between diabetics with insulin-dependent or insulin-independent diabetes. Patients diagnosed with diabetes mellitus had an increased risk for significantly inferior clinical outcomes related to newly created AV grafts, including lower rates of mid-term functional patency and higher rates of worse post-operative outcomes when compared to diabetics who received AV fistulas.

A Novel Approach for Reducing Catheter Associated Urinary Tract Infections in Intermittent Catheter Users

Catheter-associated urinary tract infections (CAUTI) are a recurring problem for individuals with neurogenic bladder who rely on frequent intermittent catheterization. Dysbiosis of the urine microbiome, characterized by the presence of pathogenic organisms and insufficient levels of Lactobacilli, is common in this population. We propose that introducing beneficial Lactobacilli via a catheter lubricant could act as a prophylactic "live barrier" to enhance beneficial bacteria in the urethra. The IC TF1 Catheter Lubricant gel discussed in this study is a freshly prepared viscous gel composed of sterile gelling components and a dry Lactobacillus Rhamnosus spp. powder. The gel prepared on- site by simple mixing, is usable for 24 hours with predictable and precise viability counts. Our investigation focuses on the design, physical attributes, manufacturability with quality control criteria, stability of probiotic viability, antimicrobial properties, cellular toxicity, and tissue compatibility of the IC TF1 gel. The gel demonstrates promising physical properties and biocompatibility, leading to the need for further pre-clinical and human trials to assess its safety and effectiveness in reducing pathogenic urethral colonization. The localized delivery of probiotic supplementation through catheter lubrication has the potential to enhance the well-being of individuals with neurogenic bladder and aid in the management of CAUTI.

Bladder irrigation with tap water to reduce antibiotic use for urinary tract infections in catheter users.

To evaluate the safety and effectiveness of bladder irrigation (BI) with tap water to reduce antibiotic use for the treatment of urinary tract infections (UTIs) in patients with recurrent UTI symptoms and to assess the treatment satisfaction of BI. This prospective, observational study included patients with an indwelling catheter or performing clean intermittent catheterisation (CIC) who had recurrent UTI symptoms between July 2022 and March 2024. BI with tap water was used for the treatment of UTIs without systemic symptoms (e.g., fever, flank pain or delirium). Patients started daily irrigation at the onset of UTI symptoms and used a tapering schedule. The number of antibiotic treatments for UTIs, UTI incidence rate ratio (IRR), UTI-related hospitalisations, treatment satisfaction and quality of life (QoL) were compared between a 3-month period before and after BI with tap water. A total of 60 patients were included with a median (interquartile range) age of 64.5 (50.4-72.6) years, 66.7% were male, and 83.3% were performing CIC. Antibiotic use was decreased on average by 38.1% (IRR = 0.62; P = 0.016) and catheter-associated UTIs by 37.9% (IRR = 0.62; P = 0.005). No increase was observed in the incidence of UTIs with systemic symptoms or UTI-related hospitalisations. In addition, no differences were observed in the health-related QoL. The majority of patients were positive about the subjective effectiveness (81%), ease of use (86%) and overall satisfaction (85%) of BI with tap water. These findings emphasise the potential of BI with tap water as a promising and patient-friendly alternative for the treatment of UTIs in patients with urinary catheters. BI with tap water significantly reduces antibiotic use and UTI incidence in patients with recurrent UTIs and is a safe and patient-friendly alternative that can be easily implemented in the management of UTIs.

Implementation of a Standardized Process of Coude Catheter Insertion Decreases Traumatic Catheterizations

ObjectiveTo address the issue of traumatic foley catheterization we developed and implemented a coude catheter education program for operating room nurses as well as standardize the usage of a coude catheter for male patients. Traumatic catheterization leads to patient morbidity and increased healthcare costs. MethodsA retrospective review was conducted to identify all traumatic catherizations over a 6-month period for several surgical services at our institution. A nursing education program was implemented that included basic urological anatomy, coude urethral catheter insertion techniques, and catheter safety. We conducted our trial over a period of 2-months with all catheterizations tracked. Following the trial, the process and outcomes were reviewed and then implemented for all male patients >18 years old requiring indwelling catheter placement in the operating room. ResultsOn retrospective review there were 18 traumatic foley catheterizations of patients on the three surgical services out of a total 601 catheter placements (3% traumatic placement rate). The total cost of these traumatic catherizations was $27,793 when accounting for additional procedures, supplies, and additional OR time required for each traumatic catheterization. The average cost per patient was $1,544. After full implementation of the process across all operating room services in June 2021 there have been 2038 catheterizations performed using a coude catheter kit with 4 traumatic foley placements through May 2022 (0.2% traumatic catheterization rate). ConclusionImplementation of the nursing education program and utilization of the coude catheter for all male catheterizations reduces costs, decreases iatrogenic urethral injury, and improves patient safety.

Holmium laser enucleation of the prostate versus transurethral resection of the prostate in treatment of benign prostatic hyperplasia: A meta-analysis of 13 randomized control trials

Abstract Background The prevalence of benign prostatic hyperplasia (BPH) in older men increases with age, beginning at 40–45 years and reaching to 60% by 60 years and 80% by 80 years. Surgical procedures such as holmium laser enucleation of the prostate (HoLEP) and transurethral resection of the prostate (TURP) are the preferred treatments for BPH. Nevertheless, there is disagreement regarding the most efficient and safe treatment for BPH. The objective of this meta-analysis was to assess the efficacy and safety of HoLEP and TURP based on existing evidence. Materials and methods This meta-analysis was performed in accordance with the PRISMA guidelines. In February 2023, a literature review was conducted using PubMed, ScienceDirect, and the Cochrane Library, and the meta-analysis was performed using RevMan V.5.4. Results A total of 656 patients underwent HoLEP, and 653 patients underwent TURP. There was no statistically significant difference in the International Prostate Symptom Score at 1 month or at 3, 6, 18, 24, and 36 months; the HoLEP group showed a significant difference at 12 months. The pooled data from the maximum urinary flow rate at 1–12 months revealed no significant findings, but the TURP group showed significant results at 24 months. Meanwhile, the HoLEP group showed significant postvoid residual results. There was no significant difference in the quality of life between the groups. Patients who underwent HoLEP had shorter hospital stay and catheter usage period and had lower hemoglobin drop. The operating time was shorter in the TURP group. The difference in specimen weight between the 2 groups was not statistically significant. The overall complications were similar in both groups, but the HoLEP group received significantly fewer blood transfusions. Conclusions Holmium laser enucleation of the prostate demonstrated excellent efficacy and safety, with fewer hematological changes and complications; however, TURP had a shorter operating time.

Evaluating the Effectiveness of Enoxaparin in Treating Pediatric Arterial Thrombosis in Saudi Arabia.

Thrombosis is the abnormal formation of blood clots within blood vessels; it results from an imbalance between fibrinolytic, pro-coagulant, and anticoagulant systems. Pediatric arterial thrombosis, especially related to catheter usage, is an emerging issue with limited evidence. This study evaluates the efficacy of enoxaparin in treating arterial thrombosis in pediatric patients at a single center. A retrospective single-center study included children under 14 years old diagnosed with catheter-related arterial thrombosis (CAT) and treated with low-molecular-weight heparin (LMWH) at King Abdulaziz Medical City between 2016 and 2021. Patients without follow-up at our institution or those using other anticoagulants were excluded. Data collected included age, sex, weight, catheter type, location and degree of thrombosis, ultrasonographic results, treatment duration, hemoglobin and platelet levels, and missed refills. Radiologic confirmation of CAT was required for inclusion. This study included 111 children treated with enoxaparin for non-cerebral arterial thrombosis. The median age at diagnosis was 3 months, with 58% being male patients. Most cases (87%) involved cardiac catheterization, and all were confirmed using ultrasonography. Complete thrombus resolution was achieved in 90% of patients, partial resolution in 8.1%, and 1.8% had no resolution. The median duration of enoxaparin therapy was 20 days. Multivariate analysis indicated that higher age and lower body weight were associated with a higher risk of non-resolution. Indwelling catheters also posed a greater risk of non-resolution compared to cardiac catheters. Enoxaparin proved effective in treating catheter-related arterial thrombosis in children, with high resolution rates and few side effects. This study helps inform treatment strategies in pediatric thrombosis management and highlights the need for further research to refine treatment durations and address patient risk factors.

Catheter Selection in Home Parenteral Nutrition Patients and Noteworthy Definitions in The Diagnosis of Catheter Infections

The rising number of patients in need of long-term parenteral nutrition has necessitated home parenteral nutrition. Extended usage of central venous catheters and parenteral nutrition has given rise to its own complications. Among them, catheter-related bloodstream infections (CRBSI) are linked to life-threatening complications, especially sepsis, septic shock, and metastatic infections. The principal objective of this review is to define diagnostic methods, notable clinical and laboratory findings, and catheter salvage strategies towards preventing CRBSI, which include defining and interpreting blood culture and its results, its confounding variables and common shortcomings in routine practice. We will discuss the types and relative advantages and disadvantages of differing methods of central venous access and compare the common diagnostic definitions used by existing guidelines. CRBSI remains a serious complication, and we aim to debate when timely intervention will be necessary in light of the existing literature.

Left Ventricular Perforation Following Transcutaneous Pigtail Catheter Placement Mimicking Anterior Wall Myocardial Infarction: An Unusual Complication.

In modern medical practice, procedures that involve the use of catheters are common. These procedures can range from percutaneous coronary and peripheral vascular interventions to using catheters to drain fluid. However, complications associated with catheter usage can arise, and the most severe one is the puncture of a vital organ due to catheter misplacement. In this case, we present a rare complication related to the use of a pigtail catheter, which caused perforation of the left ventricular free wall. The patient presented with an electrocardiogram showing ST segment elevation in the anterior wall, indicative of a heart attack. The patient underwent coronary angiography, which showed that the coronary arteries were unblocked. However, during the procedure, the medical team suspected that the pigtail catheter was stuck in the left ventricle chamber, based on the use of fluoroscopy. This suspicion was later confirmed using computer tomography. To address the issue, the patient underwent an emergent cardiorrhaphy, which was performed immediately. Fortunately, the patient survived the complication.

Characteristics and Prevalence of Vancomycin-variable Enterococcus faecium bacteremia in southern Taiwan

BackgroundVancomycin-variable enterococci (VVE) are vanA-carrying Enterococcus faecium that are phenotypically susceptible to vancomycin and can only be detected using molecular methods, leading to the possibility of treatment failure and posing threats to infection control. This study aimed to determine the prevalence of VVE and its associated clinical risk factors. MethodsThis retrospective study was conducted in two hospitals in southern Taiwan. Patients with phenotypically vancomycin-susceptible E. faecium bacteremia were enrolled between 2017 and 2021. VVEs were defined as isolates harboring the vanA gene that were phenotypically susceptible to vancomycin. Vancomycin-susceptible E. faecium (VSE) isolates were phenotypically susceptible to vancomycin and lacked vanA or vanB genes. ResultsOf the 142 enrolled patients, 121 (85.2%) had VSE and 21 (14.8%) had VVE. Resistance rates to penicillin, tetracycline, and fosfomycin were higher in VVE isolates. Malignancy (adjusted odds ratio [aOR] = 4.87; 95% confidence interval [CI] 1.54–15.41, p = 0.007) and central venous catheter usage (aOR = 4.69; 95% CI 1.49–14.78, p = 0.008) were the independent risk factors associated with VVE bacteremia. Being male (aOR = 0.12, CI 0.03–0.44, p = 0.002) was less likely to be associated with VVE bacteremia. Although VVE was not associated with 30-day mortality (38.1% [VVE] vs. 35.5% [VSE], p = 0.822), one case of subsequent vancomycin-resistant enterococci infection in the VVE group with vancomycin treatment (4.8%, 1/21) was identified, which led to subsequent mortality. ConclusionsThe prevalence of VVE was high among E. faecium isolates with vancomycin-susceptible phenotypes in southern Taiwan. Although the current study revealed that VVE bacteremia was not associated with poor clinical outcome, further multicenter surveillance survey is recommended to evaluate the possible impact of VVE on public health in Taiwan.

Efficacy and Safety of Urethral Catheter with Continuous Infusion of Ropivacaine after Urologic Surgery: A Pilot Prospective Randomized Controlled Trial.

Catheter-related bladder discomfort (CRBD) has been found in many patients with urologic surgery. The authors investigated the effect of analgesic-eluting urethral catheters on postoperative CRBD. 60 subjects scheduled for urologic surgery requiring urethral catheterization were randomized prospectively to one of three groups (control arm, 0.5% ropivacaine 1 mL/h arm [Study 1 arm] and 0.5% ropivacaine 2 mL/h arm [Study 2 arm]; n = 20 each). The incidence and severity of CRBD were evaluated postoperatively at 24 h as primary outcomes. The incidence of adverse events regarding urethral catheter utilization was assessed as a secondary outcome. The CRBD incidence at 24 h postoperatively in the control, study 1 and study 2 arms was 50.0%, 10.0%, and 15.0%, respectively (p = 0.002). The CRBD severity at 24 h postoperatively showed that patients in the study 1 and study 2 arms had significantly less postoperative CRBD than those in the control arm (visual analog score [VAS]; the mean VAS of the control, study 1, and study 2 arms: 2.1 vs. 1.6 vs. 0.9, p = 0.045). Urethral pain regarding catheter was significantly less severe in the study arms than in the control (VAS score: 6.2 vs. 1.5 vs. 1.4, p < 0.001). The severity and incidence of adverse events did not differ significantly among groups (p = 0.287). Peri-catheter leakage was more frequent in the study 2 arm (p = 0.057). The proper usage of a ropivacaine-eluting catheter can not only alleviate CRBD but reduce catheter-related urethral pain in patients with urologic surgery followed by catheterization, without major adverse events.

Incidence of fatal and non-fatal pulmonary thromboembolism after removal of tunnelled central venous haemodialysis catheters without ultrasound scan and anticoagulation.

Catheter related thrombosis is a common complication of tunnelled central venous catheter (TCVC) usage. There are concerns that TCVC removal could dislodge a thrombus to cause pulmonary thromboembolism (PE). The incidence of PE following TCVC removal is unclear and so the aim of this study was to investigate the incidence of PE and whether it is high enough to warrant screening with ultrasound with a view to systemic anticoagulation prior to TCVC removal. 1102 consecutive TCVC removals without ultrasound and systemic anticoagulation were included in this retrospective study. Data were extracted from electronic health records. Measures to identify PE events included: deaths, computed tomography pulmonary angiogram (CT-PA), isotope lung perfusion scans and D-dimers blood tests within 7 days of removal. Of the 1102 TCVC removals, the mean age of patients was 56.9 years and 57.3% were male. The primary renal diagnosis for 24.5% of patients was diabetic nephropathy. There were seven deaths following removal, none of which had PE as a contributing cause on review of their clinical history and death certificates. Five CT-PAs and one isotope lung perfusion scan were carried out in the 7 days after TCVC removal and none had a positive finding of PE. Three patient had D-dimers measured in blood within 7 days and none of these patients were subsequently diagnosed with PE. There was no evidence of fatal or non-fatal PE's occurring in the 7 days following TCVC removal. This would support the practice of removing TCVCs without the need for ultrasound screening and without a period of systemic anticoagulation.

Assessment of a Protocol for Reducing Indwelling Urinary Catheter Usage: Reduced Infection Without Increased Acute Kidney Injury.

Introduction In 2019, a level one trauma center in St. Louis, Missouri launched a campaign to reduce the use of indwelling urinary catheters (IUC) in the trauma population.Our study assesses whether the campaign achieved the intended effect of reducing catheter-associated urinary tract infection (CAUTI) and whether this came at the cost of increased acute kidney injury (AKI). Methods We examined a cohort of patients from before and after the IUC reduction campaign.We compared days with IUC, UTI, CAUTI, and AKI, both recorded in the registry and based on a direct review of laboratory results.Significance testing is performed with the Student's t-test for continuous variablesand Fisher's exact test for categorical variables.For multivariate analysis, multivariate linear regression is used for continuous outcomes, and multivariate logistic regression is used for binary categorical outcomes. Results On average, the post-campaign cohort was older and more severely injured.There was a modest decrease in IUC usage following the campaign, which was significant when adjusted for common trauma covariates, B=-0.93; p=0.04.There were 10 (0.4%) cases of CAUTI in the pre-intervention group versus 0 post-intervention (p=0.002).Pyuria was significantly lower post-intervention: 118 (40.3%) versus 84 (29.3%), p=0.007.This remained significant on multivariate analysis: odds ratio (OR): 0.52, p=0.008.There were no significant differences in creatinine (Cr) absolute values or temporal trends over the course of admission between the cohorts.There was no increased AKI measured by kidney disease improving global outcomes (KDIGO) criteria. Conclusion The IUC reduction protocol was associated with a significant decrease in CAUTI without a significant increase in AKI.

Drug-Coated Central Venous Catheters – A Comprehensive Review of Strategies in the Development to Overcome Biofilm Formation and Related Infections

Central venous catheters (CVCs) are implantable medical instruments regularly used in intense care units for the easy introduction of medical drugs and medicaments, to give fluids intravenously, nutriments, transfusion of blood and also to withdraw blood samples. Bloodstream infections associated with the usage of catheters are the most recurrent, harmful as well as expensive impediment. This is the omnipresent reason for the introduction of bacteria and related infections. Among the various types of medical devices, the rate of infection, morbidity and mortality are higher with the usage of CVCs than any other types of medical instruments. Biofilm developed due to contamination by microorganisms. The biofilm is a bunch of microorganisms accumulated on the surface of CVCs. These biofilms contribute to the proliferation of microbes and increase antimicrobial resistance against antibiotics, affect the host’s immunity and get spread to the various body parts. Numerous approaches have been evolved to overcome the above mentioned issues associated with the usage of CVCs. In the said review, the authors have summarized the usage of CVCs, biofilm formation, development of infection, strategies and innovations in the modification of CVCs aiming to avoid the CRBSI and subsequent resistance to antimicrobial drugs.

ISR 14 - Implementing Initiatives to Reduce Catheter Usage and Catheter-Associated Urinary Tract Infections in Acute Care Hospitals

ISR 14 - Implementing Initiatives to Reduce Catheter Usage and Catheter-Associated Urinary Tract Infections in Acute Care Hospitals

The role of glomerular filtration rate in AVF success: Should we intervene earlier?

End-stage kidney disease (ESKD) patients require life-sustaining kidney replacement therapies, with the natural arteriovenous fistula (AVF) being the preferred vascular access due to its low infection risk, high patency, and fewer complications. Factors like vessel diameter, gender, diabetes, age, and surgical technique influence AVF maturation. Our study focused on short-term AVF creation success, specifically examining estimated glomerular filtration rate (eGFR) levels using the CKD-EPI formula. Patients were categorized according to their eGFR levels to observe the effects of fistula timing and the severity of kidney disease. No significant demographic or outcome differences between eGFR groups have been observed except for gender. AVF maturation was notably associated with distal vein diameter (>2mm), while other factors did not significantly impact maturation rates. As a secondary outcome, it was concluded that the recording of patients' blood pressure values at preoperative and perioperative levels led to the conclusion that blood pressure levels may have an impact on fistula maturation. To ensure vascular access effectiveness, optimizing blood pressure, determining vein diameter, strategic AVF timing, and reducing catheter usage are crucial. Our study aimed to identify eGFR levels conducive to optimal AVF outcomes. Although significant results could not be obtained in this regard, it is considered worthwhile to re-examine the effect of blood pressure in secondary outcomes. Additionally, prospective studies may be appropriate for reevaluating the effect of GFR.

Assessment of Urinary Dysfunction After Midurethral Sling Placement: A Comparison of Two Voiding Trial Methods

Study objectiveTemporary urinary retention after midurethral sling (MUS) surgery requiring indwelling catheter or self-catheterization usage is common. Different methods for assessment of immediate postoperative urinary retention have been described. The aim of this study was to compare postoperative voiding trial (VT) success following active versus passive voiding trial in women undergoing MUS surgery.Design: Comparative retrospective cohort study. SettingFemale pelvic medicine and reconstructive surgery practice at a university affiliated tertiary medical center. PatientsPatients with stress urinary incontinence who underwent surgical treatment during the study period were eligible for inclusion. Excluded were patients under the age of 18, combined cases with other surgical services, planned laparotomy, patients with history of urinary retention and patients for whom their VT was performed on postoperative day 1. The cohort was divided into two groups: 1) patients who underwent an active retrofill of their bladder using a Foley catheter; 2) patients who were allowed to have a spontaneous void. Interventionsnone. Measurements and main resultsTwo hundred and eighty-five patients met the inclusion criteria for the study. Of these subjects, 94 underwent an active voiding trial and 191 underwent a passive voiding trial. There were no statistically significant differences in immediate postoperative urinary retention (30.8% vs. 29.3%, p=0.79) or time from surgery end to voiding trial (233.0 ± 167.6 minutes vs. 203.1 ± 147.8 minutes, p=0.13) between groups. Urinary retention, as defined by a failed voiding trial, increased from 10% to 29.3% when MUS placement was accompanied by concomitant prolapse repair procedure. Multivariate logistic regression analysis revealed that undergoing a combined anterior and posterior colporrhaphy (OR 5.13, p <0.001) as well as undergoing an apical prolapse procedure (OR 2.75, p=0.004) were independently associated with immediate postoperative urinary retention while increased BMI (OR 0.89, p<0.001) lowered likelihood of retention. ConclusionThe method used to assess immediate postoperative urinary retention did not affect VT success. Concomitant combined anterior and posterior colporrhaphy and apical suspension were correlated with greater likelihood of VT failure while increased BMI decreased odds of retention.
