COMPREHENSIVE ANALYSIS OF CATHETER-ASSOCIATED URINARY TRACT INFECTIONS: RISK FACTORS, MICROBIAL DYNAMICS, AND ANTIMICROBIAL CHALLENGES IN A TERTIARY CARE SETTING

Introduction: Indwelling urinary catheters are frequently employed in medical procedures; yet, they pose a considerable risk, with catheter-associated urinary tract infections (CAUTIs) being a global healthcare challenge. CAUTIs account for 30–40% of nosocomial infections, contributing to heightened morbidity and mortality. Objective: Our objectives included investigating CAUTI incidence, exploring factors contributing to UTI risk, examining the correlation between bacteriuria and symptomatic CAUTI, and recording microbiological profiles and antibiotic sensitivities for insights into microbial dynamics and treatment strategies. Method: We aimed to assess patient and catheter-related factors influencing urinary tract infections (UTIs) in 105 catheterized patients. Results: Among the studied cohort, with an average age of 47.73 years, various catheter sizes were employed, and post-operative catheterization was the predominant indication. Microbial presence in urine samples was detected in 31.4% of cases, with a 21% prevalence of symptomatic UTIs. Diabetes mellitus showed a significant association with increased UTI occurrences (p=0.019). Notably, catheterization outside the operating theater (OT) and prolonged catheterization duration were significantly associated with increased infection rates (p=0.000 and p=0.003, respectively). Despite antibiotic treatment, Escherichia coli remained the most prevalent organism causing infection (17.1%), and antibiotic resistance trends were observed, highlighting the challenges of antimicrobial stewardship. Conclusion: The study emphasizes the importance of preventive measures, such as reducing catheterization duration and meticulous diabetes management, to mitigate the burden of CAUTIs. In conclusion, this study provides valuable insights into the prevalence, risk factors, and microbial dynamics of CAUTIs, urging a shift toward proactive prevention strategies and judicious antibiotic use to enhance patient outcomes and alleviate the strain on health-care resources.

A 27-Year Experience With Day Surgery Transurethral Resection of the Prostate.

Introduction Transurethral resection of the prostate (TURP) is the standard surgical procedure forobstructive symptoms of the lower urinary tract when medical management fails. Progression in TURP procedures has led to reduced catheterization time following transurethral prostatic resection. This study describes the methods and results of TURP performed in the day surgery setting. Materials and methods This retrospective study was performed at a day surgical hospital serving a patient population of more than 200,000 people. Over a 27-year period, a total of 1,123 patients with a mean age of 73.6 years (range: 49 to 91 years) underwent same-day conventional (electrosurgical monopolar) transurethral prostatic resection. Of the procedure, 43 patients (11%) received spinal anaesthesia, and the remainder received general anaesthesia. Results Over the years, there has been an increase in the use of medication to manage bladder outflow obstructive symptoms, which has led to the preoperative post-micturition volumes of urine being increased (>200 ml) at the time of surgical intervention. The mean American Urological Association (AUA) score was 22 (range: 10-35). Due to the reduced bladder tone preoperatively and the noted intraoperative distension of the bladder, early catheter removal is contraindicated in these patients. The mean duration of catheterization was 6.4 days (range: two to 28 days). No patient was readmitted to the hospital for retention of urine. However, 11 patients in the series had re-catheterization due to failure of micturition after the removal of the catheter. No patients were admitted to the hospital for clot retention or sepsis postoperatively. This resulted in the patients being discharged home with a catheter in place, which became our standard practice. Conclusion Conventional transurethral resection of the prostate can be effectively managed in the day surgery setting with minimal morbidity. This improves the patient's quality of life as well as the burden on hospital costs. Additionally, the outpatient nature of day surgery may lead to decreased overall healthcare expenses for both the patient and the healthcare system. As healthcare systems continue to prioritize streamlined and patient-centred approaches, day surgery for TURP emerges as a viable and advantageous option.

Description of a novel robotic early post-prostatectomy anastomotic repair technique and institutional outcomes

ObjectiveA vesicourethral anastomotic leak (VUAL) is a known complication following robotic-assisted radical prostatectomy. The natural history of a VUAL has been well described and is frequently managed with prolonged catheterization. With increasing emphasis on patient reported outcomes, catheter duration and VUAL are associated with significant short-term quality of life impairment. We aimed to present a case series of our robotic early post-prostatectomy anastomotic repair technique, defined as revision within 6 weeks from index surgery. MethodsA single institution prospective database identified eleven patients with a VUAL from July 2016 to October 2022 who underwent robotic early post-prostatectomy anastomotic repair by a single surgeon. Patients were diagnosed with a VUAL on pre-operative CT urogram or CT/fluoroscopic cystogram. The primary outcome was resolution of the anastomotic leak, defined as no contrast extravasation on post-operative cystography. Secondary outcomes included post-repair catheter duration and continence on the last follow-up defined as pad(s) per day. ResultsThe mean time to intervention after robotic-assisted radical prostatectomy was 21 days. Eight of the eleven (72.7%) patients had no evidence of extravasation on post-repair cystogram. The range from intervention to first cystogram was 7–20 days. The median catheter duration for those with successful intervention was 10 days. The median catheter duration for those with the leak on initial post-operative cystogram was 20 days. At a mean follow-up time of 25 months, eight (72.7%) patients reported using no pads per day, and three (27.3%) patients reported one pad per day. ConclusionManagement of a VUAL has traditionally relied on prolonged catheter drainage and the tincture of time. As the role of robotic reconstruction has been shown to be a viable modality for management of bladder neck contracture, it is important to reconsider prior dogmas of urologic care. Our case series suggests that an early repair is safe and has a high success rate. Early robotic intervention gives providers an additional tool in aiding patient recovery.

Neuropathic pain after orthopaedic surgery with continuous peripheral nerve block.

Continuous peripheral nerve blocks (cPNBs) have shown favourable post-operative pain control results but may be associated with a risk for long-term neurological complications. This study sought to examine factors associated with persistent post-operative pain and potential neuropathy after orthopaedic lower-limb surgery with the use of post-operative cPNB. Patients who underwent lower limb orthopaedic procedures with cPNBs between November 2021 to May 2022 were included. Patient demographics and perioperative data were noted. At discharge, patients completed the PainDetect (PD) questionnaire and were followed up six months after discharge. Seventy-seven patients with a total of 171 catheters completed the follow up. The median time to follow-up was 214 days after catheter removal, and 18 patients (23%) had a PD score ≥ 13. Univariate analysis showed that multiple variables were associated with a PD score ≥ 13 at the six-month follow-up. Multiple logistic regression showed that a high PD score at discharge, high BMI and longer duration of cPNBs were associated with higher risk of having a PD score ≥ 13 at the six-month follow-up. Several factors were associated with a higher risk of having possible neuropathy after six months. BMI, duration of catheter and PD score at discharge were correlated with risk of possible neuropathic pain. None. The study was a quality control project and therefore did not require registration under Danish law.

Does Anterior Plating of Pelvic Ring Fractures Increase Infection Risk in Patients With Bladder or Urethral Injuries?

Evaluate the effect of anterior fixation on infection in patients with operative pelvic fractures and bladder or urethral injuries. Retrospective. Eight centers. Adult patients with closed pelvic fractures with associated bladder or urethral injuries treated with anterior plating (AP), intramedullary screw (IS), or no anterior internal fixation (NAIF, including external fixation or no fixation). Deep infection. There were 81 extraperitoneal injuries and 57 urethral injuries. There was no difference in infection between fixation groups across all urologic injuries (AP: 10.8%, IS: 0%, NAIF: 4.9%, P = 0.41). There was a higher rate of infection in the urethral injury group compared with extraperitoneal injuries (14.0% vs. 2.5%, P = 0.016). Among extraperitoneal injuries, specifically, there was no difference in deep infection related to fixation (AP: 2.6%, IS 0%, NAIF: 2.9%, P = 0.99). Among urethral injuries, there was no statistical difference in deep infection related to fixation (AP: 23.1%, IS: 0%, NAIF: 7.4%, P = 0.21). There was a higher rate of suprapubic catheter (SPC) use in urethral injuries compared with extraperitoneal injuries (57.9% vs. 4.9%, P < 0.0001). In the urethral injury group, SPC use did not have a statistically significant difference in infection rate (SPC: 18.2% vs. No SPC: 8.3%, P = 0.45). Early removal of the SPC before or during the definitive orthopaedic intervention did not significantly affect infection rate (early: 0% vs. delayed: 25.0%, P = 0.16). Surgeons should approach operative pelvic fractures with associated urologic injuries with caution given the high risk of infection. Further work must be done to elucidate the effect of anterior implants and SPC use and duration. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Urinary catheter placement and adverse urinary outcomes with a focus on elevated risk in men with indwelling Foley catheters.

Prior studies indicated a link between urinary catheter use and urinary complications, highlighting the need for comprehensive, gender-specific investigations. This study explored the association through a national retrospective cohort, emphasizing gender disparities and long-term outcomes. Our study utilized data from the entire population covered by Taiwan's National Health Insurance Research Database from 2000 to 2017. We included 148,304 patients who had undergone Foley catheter placement and their propensity-scores matched controls in the study. We evaluated urinary complications, which encompassed urinary tract cancer, urolithiasis, urethral stricture, obstructive uropathy, reflux uropathy, fistula, diverticulum, caruncle, false passage, prolapsed urethral mucosa, urinary tract rupture, and urinary tract infection. These were assessed using the Fine and Gray sub-distribution proportional hazards model to compare between the Foley and non-Foley groups. Sensitivity analyses were conducted with different matching ratios. In the study, the non-Foley group presented a marginally higher mean age (75.24 ± 10.47 years) than the Foley group (74.09 ± 10.47 years). The mean duration of Foley catheterization was 6.1 ± 4.19 years. Men with Foley catheterization exhibited the highest adjusted sub-distribution hazard ratios for urinary tract cancer (6.57, 95% CI: 5.85-7.37), followed by women with Foley catheterization (4.48, 95% CI: 3.98-5.05), and men without catheterization (1.58, 95% CI: 1.39-1.8) in comparison with women without the procedure. Furthermore, men with Foley catheterization were found to be at the greatest risk for complications such as urolithiasis, urethral stricture, obstructive and reflux uropathy, fistula, diverticulum, caruncle, false passage, prolapsed urethral mucosa, and urinary tract rupture. Conversely, women with urinary catheterization were most susceptible to urinary tract infections. The evidence confirms that urinary catheterization significantly increases urinary complications, particularly among men. Our study underscores the crucial need for healthcare providers to carefully evaluate the necessity of catheterization, aim to shorten its duration whenever feasible, and strictly adhere to established protocols to minimize complications.

Reduction of Urinary Tract Infection in Pediatric Surgical Patients Using NSQIP-P and Quality Improvement Methodology.

Hospital-acquired urinary tract infections (UTIs) have a detrimental effect on patients, families, and hospital resources. The Sydney Children's Hospital Network (SCHN) participates in the NSQIP-Pediatric (NSQIP-P) to monitor postoperative complications. NSQIP-P data revealed that the median UTI rate at SCHN was 1.75% in 2019, 3.5 times higher than the NSQIP-P target rate of 0.5%. Over three quarters of the NSQIP-P identified patients with UTI also had a urinary catheterization performed intraoperatively. A quality improvement project was conducted between mid-2018 and 2021 to minimize catheter-associated UTIs (CAUTIs) at SCHN. NSQIP-P samples include pediatric (younger than 18 years) surgical patients from an 8-day cycle operative log. NSQIP-P data are statistically analyzed by the American College of Surgeons and provide biannual internationally benchmarked reports. The project used clinical redesign methodology with a 6-phase process for quality improvement projects. The objectives of the project were to reduce urinary catheter duration of use, educate parents or carers, and improve catheter care and insertion technique by health staff. The duration of a urinary catheter in situ reduced from a median of 4.5 to 3 days from 2017 to 2021. The median NSQIP-P UTI rate at SCHN was reduced by 47.4% from 1.75% in 2019 to 0.9% in 2022. A multifactorial approach in quality improvement has been shown to be an effective strategy to reduce UTI rates at SCHN, and patient outcomes were improved within a 3-year timeframe. Although this project has reduced UTI rates at SCHN, there remain opportunities for further improvement.

Clinical Efficacy of Modified Nonmesh Sacral Colpopexy for Pelvic Organ Prolapse

Importance As an increasing number of mesh-related complications have been reported, the availability of nonmesh alternatives becomes crucial for situations where mesh is not desired or unavailable. A new modified procedure of nonmesh laparoscopic sacral colpopexy (LSC) was performed in our department, which used a nonabsorbable polyester suture (Ethibond) combined with uterosacral ligament suspension. Objective The aim of this study was to evaluate the clinical efficacy of the modified procedure in comparison with traditional LSC in patients with pelvic organ prolapse. Methods This retrospective study assessed the treatment outcomes of 60 patients who were underwent LSC with or without mesh from January 2017 to April 2019. Patients were divided into 2 groups based on the presence or absence of mesh during the operation: mesh group (n = 34) and nonmesh group (n = 26). General data, perioperative indexes, postoperative complications, and recurrence rates were comparatively analyzed between 2 groups. Results In perioperative indexes, the nonmesh group exhibited shorter operation time (P &lt; 0.001) and less intraoperative blood loss compared with the mesh group (P = 0.004). There was no significant difference in postoperative indwelling urinary catheter duration (P = 0.425) and hospitalization time (P = 0.827) between the 2 groups. In postoperative complications, the incidence of postoperative complications showed no significant difference between the 2 groups (P &gt; 0.05). No occurrences of mesh exposure and erosion were observed in the mesh group during at least a 2-year follow-up period. In postoperative recurrence, none of the patients in either group experienced prolapse recurrence. Conclusions In comparison with the traditional LSC with mesh, the modified laparoscopic nonmesh sacral colpopexy presents advantages of reduced surgical trauma, less pain, and lower cost. However, a long-term and large sample study is required for evaluating the surgery’s long-term efficacy.

Study of biofilm formation among uropathogens isolated from catheter-associated UTI patient from a tertiary care hospital

Background: Catheter-associated urinary tract infection (CAUTI) is a serious health threat and challenging infection. CAUTI accounts for up to 40% of all nosocomial infections. Biofilm provides a survival strategy to microorganisms and ultimately leads to re-infections and recurrence of urinary tract infections (UTI) despite a full course of antibiotics. Aims and Objectives: The present study was conducted to determine the prevalence of CAUTI in suspected UTI patients and prevalence of biofilm-forming uropathogens among CAUTI patients. Materials and Methods: The cross-sectional study was done over a period of 6 months among 95 catheterized CAUTI patients. Biofilm production among isolated uropathogens was tested by tissue culture plate, tube test, and congo red agar method. Isolates were identified as biofilm producer if they were tested positive by any one of the all four methods, and isolates were considered biofilm non-producer in consensus with all four methods. Results: In this study, the prevalence of CAUTI was 68.42%. Among 65 isolates most common uropathogen was 28 (43.07%) Escherichia coli. In this present study, the prevalence of biofilm-forming uropathogens was 58.46% (38). Tissue culture plate was the most sensitive (97.36%) method in detecting biofilm formation followed by modified congo red agar (82.21%), congo red agar (71.05%), and tube test (65.78%). Biofilm productions were significantly associated with female gender, diabetes, and prolonged catheterization. Conclusion: Indwelling urinary catheter acts as a nidus for biofilm formation among microorganisms. Duration of catheterization is inversely associated with UTI. Hence, the need for catheter removal should be assessed daily to prevent infection. Periodic surveillance should be done to detect biofilm formation where prolonged catheterization is inevitable.

Pritchard's Regimen: The Effect of 12-Hour Versus 24-Hour Magnesium Sulphate Maintenance Regimen on the Occurrence of Seizures and Maternal Outcome in Women with Severe Features of Preeclampsia: A Triple-Blind Randomized Controlled Trial.

Magnesium sulphate (MgSO4) administered for twenty-four hours is the drug of choice for seizure prophylaxis in patients with preeclampsia with severe features. Due to its narrow therapeutic index, a reduction in the duration of MgSO4 administered in the postpartum period may not only prevent the occurrence of seizures but also reduce the adverse effects associated with this drug. This study aimed to compare the efficacy of the 12-hour and 24-hour Pritchard's MgSO4 maintenance regimen on the occurrence of seizures and maternal outcomes in patients with preeclampsia with severe features. A triple-blind randomized controlled trial was conducted among women with preeclampsia with severe features between 1st June 2022 and January 31st, 2023. The primary outcome measure was the occurrence of seizure in either arm of the study. One hundred and forty-six women were randomized into two groups, those who received a 12-hour MgSO4 regimen and placebo for the remaining twelve hours (Group I) and those who received a 24-hour MgSO4 regimen in the postpartum period (Group II). The collected data was coded and analyzed using Statistical Product and Service Solutions (SPSS) version 26 and p<0.05 was considered significant. There was no statistically significant difference between the two groups concerning the occurrence of seizures, the need to recommence MgSO4, clinical evidence of toxicity and adverse effects of MgSO4. There was also no statistically significant difference between the two groups in the total dose of MgSO4 administered, duration of urethral catheterization and duration of hospital admission. No maternal mortality was recorded in this study. The results of this study suggest that the 12-hour MgSO4 maintenance regimen is as efficacious as the traditional 24-hour regimen in preventing seizures without worsening maternal outcomes.

Catheter-associated urinary tract infections in critically Ill patients with COVID-19: a retrospective cohort study.

Catheter-associated urinary tract infections (CA-UTIs) pose a significant challenge in intensive care unit (ICU) patients with COVID-19. The study aims to assess the prevalence of CA-UTIs, identify the causative pathogens and their resistance profiles, and determine the risk factors and outcomes associated with CA-UTIs in ICU patients with COVID-19. Single-center, retrospective cohort study. The study included 201 adult ICU patients diagnosed with COVID-19 between March 2020 and July 2021. Patients were categorized into CA-UTI (n = 56) and non-CA-UTI (n = 145) groups. Data on demographic characteristics, clinical course, treatment, and outcomes were collected. Logistic regression analysis was used to identify risk factors for CA-UTI. CA-UTIs developed in 28% of patients (n = 56). Incidence density of 15.8 episodes per 1000 catheter days. The average onset occurrence is 7.2 days after ICU admission. Patients with CA-UTI had longer ICU stays (18.8 days vs 10.5 days, p < 0.001) and more elevated mortality rates (75.0% vs 54.5%, p = 0.010), higher mechanical ventilation (MV) usage (98.2% vs 88.3%, p = 0.027), a longer average duration of MV (16.6 days vs 9.1 days, p < 0.001). Longer ICU and hospital stays were significant risk factors for CA-UTI. Other factors, such as the use of corticosteroids, chronic organ insufficiency or immunocompromized status, female sex, age, diabetes mellitus, and the duration of urinary catheterization, did not show significant associations with CA-UTI risk in this cohort. Gram-negative bacteria, particularly Klebsiella pneumoniae (28 cases), was the most common pathogen, with a high prevalence of multidrug resistance (38.8%) with type ESBL, MBL, NDM, and OXA-48. The occurrence of multidrug resistant (MDR) organisms was 68.8%. The findings of this study underscore the prevalence of CA-UTIs in ICU patients with COVID-19, significantly impacting patient outcomes. Effective infection control and targeted antimicrobial therapy are crucial to managing these infections.

Day surgery in the treatment of benign prostatic obstruction with photoselective vaporisation of the prostate: A single‐institution experience

AbstractAimTo assess the feasibility, efficacy and safety of performing photoselective vaporisation of the prostate (PVP) as a day‐surgery procedure for patients with benign prostatic obstruction.Patients and MethodsA prospective single‐arm observational study was performed involving patients with benign prostatic obstruction (BPO) who received PVP between 2017 and 2021. Data were collected on demographics, prostate volume by transrectal ultrasonography, mean peak flow rate (Qmax), post‐void residual urine volume, International Prostate Symptom Score (IPSS) with quality‐of‐life (QoL) index, length of stay, success in weaning off catheter on the day of operation and complications.ResultsPVP was performed successfully in all 37 men between 2017 and 2021. Their mean age was 67 years. The mean prostate volume was 54 mL. The mean duration of operation was 80 min. The mean peak urinary flow rate improved from 9.14 to 16.8, 17.3 and 15.4 mL/s at post‐operative 1, 3 and 12 months, respectively (P = .001). The mean IPSS score improved from 19.5 to 8.94, 6.40 and 5.63 at post‐operative 1, 3 and 12 months, respectively (P &lt; .001). The mean QoL index improved from 4.07 to 2.43, 2.25 and 1.81 at post‐operative 1, 3 and 12 months, respectively (P = .001). The mean duration of catheterisation after PVP was 5.81 h. Thirty‐three (89.2%) patients were discharged on the same day. Overall, the 30‐day complication rate was 27%. The most common complication was haematuria (6 patients, 16.2%). Five patients (13.5%) required readmission and inpatient care. There was one Clavien–Dindo grade III and IV complication (2.6%), respectively.ConclusionThis study demonstrated the feasibility of performing PVP as a day‐surgery procedure with good short‐ and medium‐term functional outcomes and safety profiles.

A comparative analysis of infection and complication rates between single- and double-lumen ports.

Port-a-caths are implanted intravascular chest ports that enable venous access. With more port placements performed by interventional radiologists, it is important to discern differences in infection and complication rates between double- and single-lumen ports. We retrospectively reviewed 1,385 port placements over 2 years at the University of Miami. Patients were grouped by single- or double-lumen ports. Data on duration of catheter stay, bloodstream infections, malfunctions, and other complications (fibrin sheath, thrombosis, catheter malposition) were collected. Multivariate Cox regression was performed to identify variables predicting port infection. The mean patient age was 58.8 years; the mean BMI was 26.9 kg/m2; and 61.5% of these patients were female. Our search revealed 791 double-lumen ports (57.1%) and 594 single-lumen ports (42.9%). The median follow-up was 668 days (range, 2-1,297). Double-lumen ports were associated with significantly higher rates of bacteremia (2.78% vs 0.84%; P = .02), port malfunction (8.3% vs 2.0%; P < .001), fibrin sheath formation (2.2% vs 0.5%; P < .02), catheter tip malposition (1.0% vs 0; P = .01), and catheter-associated thrombosis (1.4% vs 0; P = .003). Multivariate Cox regression analysis, after adjusting for other variables, showed that double-lumen chest ports had 2.98 times (95% confidence interval, 1.12-7.94) the hazard rate of single-lumen ports for developing bloodstream infection (P = .029). Double-lumen chest ports are associated with increased risk for bloodstream infection, malfunction, fibrin sheath formation, catheter tip malposition, and catheter-associated thrombosis. Interventional radiologists may consider placing single-lumen ports if clinically feasible; however, future studies are needed to determine clinical significance. The study limitations included the retrospective study design and the potential loss of patient follow-up.

Assessing the Safety and Effectiveness of Bipolar Technology in Transurethral Prostate Resection: A study in a Tertiary Care Private Hospital

Background: Benign enlargement of prostate (BEP) is a common affliction among aging males, predominantly emanating from the transition zone of the prostate, resulting in lower urinary tract symptoms. Despite the availability of diverse treatment modalities, transurethral resection of prostate (TURP) has conventionally served as a benchmark intervention. Recently, there has been a growing interest in bipolar energy techniques, spurred by their potential advantages in mitigating complications such as TUR syndrome and surgical bleeding. Objectives: The main aim of the study to evaluate the safety profile (including serum sodium and hemoglobin reductions, clot retention, TUR syndrome, catheterization duration, and hospital stay) and efficacy (resection rate, maximum flow rate increase, and International Prostate Symptom Score reduction) within the bipolar technique for the TURP. Methods &amp; Materials: A prospective observational study was conducted at the Department of Urology, Square Hospitals Ltd, Dhaka, Bangladesh, spanning December 2020 to November 2021. The study employed comprehensive preoperative assessments, including bipolar transurethral resection of the prostate (B-TURP) using Olympus ESG-400 energy platform. Surgical parameters, postoperative monitoring, and statistical analysis were meticulously executed to evaluate outcomes and complications for symptomatic benign enlargement of prostate. Results: In a sample of 50 individuals undergoing bipolar transurethral resection of the prostate (B-TURP), the distribution of ages revealed 66.97±7.95 years as the bipolar system's average age, ranging from 53-82 years. The majority resided in urban areas (62%), with family income predominantly in the 25000-50000 bracket (42%). Preoperative baseline variables, including IPSS, Qmax, serum hemoglobin, and sodium levels, exhibited similar values between groups. Intraoperatively, the mean resection rate was 0.56±0.16 gm/min. Postoperatively, B-TURP resulted in a slight ......

Magnitude and Factors Associated with Catheter Associated Urinary Tract Infection, and Antimicrobial Susceptibility Profile at Hawassa, Sidama Regional State, Ethiopia: A prospective Cross-sectional Study

Introduction: The use of urinary catheter benefit patients who are unable to urinate for various medical reasons. Despite its use, a urinary catheter during its application may introduce bacteria to the urinary tract and result in Urinary tract infection (UTI). Even though the burden of catheter-associated UTI is expected to be high in resource-limited countries, there is limited data. The aim of this study was to determine the magnitude of culture- confirmed catheter-associated urinary tract infection (CAUTI), associated factors, and antimicrobial susceptibility profiles of bacteria.&#x0D; Methods: This prospective cross-sectional study was conducted at Hawassa University Comprehensive Specialized Hospital (HUCSH), Sidama region, from May-August 2022. One hundred forty-nine catheterized patients at HUCSH were included. Socio-demographic, clinical, and laboratory data were collected using structured questionnaire. Urine specimens were cultured on blood and MacConkey agar. Culture-confirmed catheter-associated urinary tract infection was established if &gt;1 X 105 colonies of bacteria per milliliters of urine was detected. The disc diffusion method was used for antimicrobial susceptibility testing. For data analysis, SPSS version 26 was used. Factors associated with culture-confirmed CAUTI were assessed using binary logistic regression.&#x0D; Results: The magnitude of culture confirmed CAUTI was 30.2% (n=45; 95% CI=22.8−37.6). The most common bacterial isolates were Escherichia coli (n=12; 26.7%), followed by Klebsiella species (n=10; 22.2%), and Staphylococcus aureus (n=6; 13.3%). Duration of catheterization (AOR=9.6, 95% CI=3.8−24.2) and comorbidities (AOR=4.1, 95% CI=1.7−9.8) were significantly associated with culture-confirmed CAUTI. Most Gram- negative bacteria were resistant to commonly prescribed antimicrobial agents.&#x0D; Conclusions: The magnitude of culture-confirmed CAUTI at HUCSH was high. E. coli was the leading bacteria and most of them were resistant to various types of antimicrobial agents. Duration of catheterization and comorbidities were significantly associated with culture- confirmed CAUTI.

Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice

Diagnosis and management of complications following pelvic organ prolapse surgery using a synthetic mesh: French national guidelines for clinical practice

An analysis of the risk factors for invasive fungal infections in preterm infants and a discussion of prevention strategies.

Although the success rate of resuscitation in preterm infants is increasing, the long length of hospital stay in preterm infants and the need for more invasive operations, coupled with the widespread use of empirical antibiotics, have increased the prevalence of fungal infections in preterm infants in neonatal intensive care units (NICUs) year on year. The present study aims to explore the risk factors of invasive fungal infections (IFI) in preterm infants and to identify some prevention strategies. A total of 202 preterm infants with a gestational age of 26 weeks to 36+6 weeks and a birth weight of less than 2,000 g, admitted to our neonatal unit during the 5-year period from January 2014 to December 2018, were selected for the study. Among these preterm infants, six cases that developed fungal infections during hospitalization were enrolled as the study group, and the remaining 196 infants who did not develop fungal infections during hospitalization were the control group. The gestational age, length of hospital stay, duration of antibiotic therapy, duration of invasive mechanical ventilation, indwelling duration of the central venous catheter, and duration of intravenous nutrition of the two groups were compared and analyzed. There were statistically significant differences between the two groups in the gestational age, length of hospital stay, and duration of antibiotic therapy. A small gestational age, a lengthy hospital stay, and long-term use of broad-spectrum antibiotics are the high-risk factors for fungal infections in preterm infants. Medical and nursing measures to address the high-risk factors might reduce the incidence of fungal infections and improve the prognosis in preterm infants.

Single-Port Robotic Radical Prostatectomy Using Transvesical and Transperineal Access in Patients with a Hostile Abdomen.

Introduction: Prostate cancer diagnosis and treatment is challenging in surgically complex patients. Radical prostatectomy can be performed without peritoneal entry using novel single-port (SP) transperineal (TP) and transvesical (TV) approaches. We sought to examine the outcomes of radical prostatectomy using novel TP and TV approaches in patients with extensive prior abdominal surgeries. Materials and Methods: From 2019 to 2023, 51 patients with extensive prior abdominal surgeries were identified who underwent TP (18) and SP TV (33) robotic radical prostatectomy. Indications included history of various surgeries with open laparotomy, including J-pouch reconstruction (22, 43%), active stoma (14, 27%), and open bowel resection (9, 18%). In all patients, 12/51 (24%) had a history of incisional hernia repair with mesh. A retrospective analysis was performed. Results: All cases were completed without open conversion, bowel injuries, or blood transfusions. Length of stay was 5.6 hours for TV and 22 hours for TP. No opioids were prescribed in 91% of TV vs 56% of TP. One intraoperative complication (ureteral injury) occurred in a patient undergoing the TP approach. Postoperative complications were noted in 14/51 (27%), including 10/18 (56%) TP vs 4/33 (12%) TV. High-grade complications (Clavien 3) occurred in three patients (6%, all TP). Pathologic staging showed pT3 in 26/51 (17 TV vs 9 TP), while the remainder were pT2. Biochemical recurrences were noted in four patients (8%, three TV and one TP). Immediate continence was noted in 30% of TV patients. Long-term continence after 12 months was 92% in TV and 67% in TP. Conclusions: In patients with extensive prior abdominal surgeries, radical prostatectomy is feasible using a TP or TV approach. No bowel injuries or open conversion were observed. The SP TV approach offers advantages of shorter hospital stay, shorter catheter duration, less opioid use, fewer complications, and improved continence recovery.

Bladder tumor ablation with 980-nm and 980-/1470-nm diode lasers: a retrospective study

Abstract Purpose This study evaluated the safety and feasibility of ablation of both non-muscle invasive and muscle invasive bladder tumors using single- and dual-wavelength diode lasers (980 nm and 980/1470 nm). Methods We retrospectively examined 151 patients with bladder tumors of any type from 2009 to 2021 who underwent V-LABT (visual laser ablation of bladder tumor) with both single- and dual-wavelength diode lasers at Shalamar Hospital Lahore, Pakistan. All procedures were performed by the same surgeon. Shalamar Medical and Dental College review board approved this retrospective cohort study (IRB No. -623-2023). The collected clinical data were consolidated into a single group, encompassing various variables such as the patients’ age, tumor size, number of tumors, tumor location, tumor grade, ablation duration, postoperative catheterization time, bladder discomfort, obturator nerve reflex, intraoperative and postoperative complications, and recurrence of tumors at the ablation sites. The patients were monitored for a minimum of 12 months to observe recurrence at the ablation sites through cystoscopy performed postoperatively every three months. The data were analyzed using Chi-square test, and p value &lt; 0.05 was considered significant. Results The average age of the 151 patients was found to be 64.72 ± 13.85 years. The size of the tumors was 4.88 ± 2.16 cm, with 48/151 (31.7%) patients having tumors larger than 3 cm. Among the cases studied, 117/151 (77.4%) patients had a single tumor, while the remaining patients had multiple tumors ranging in size from 5 to 7 cm in aggregate. Ablation took 1.57 ± 0.73 h to complete on average. None of the patients required a conversion to TURBT in 151 patients. No obturator reflexes or bladder perforations were observed in any case. Postoperatively, histopathology results showed 53/151 (35%) and 92/151 (60.9%) high- and low-grade tumors. The average catheterization duration was 6.58 ± 1.47 days. Tumors located on difficult sites, such as the anterior wall, lateral wall, and bladder neck, were ablated with ease. There was no recurrence seen on previously tumor ablated sites till 12-month follow-up. Conclusion Ablation of bladder tumors of any type using single- or dual-wavelength diode laser (980 nm and 980/1470 nm) is safe and feasible. These lasers possess the capability to effectively ablate/coagulate bladder tumors in challenging anatomical locations including diverticular tumors with minimal difficulty.

Clinical outcome and safety of holmium laser prostate enucleation after transrectal prostate biopsies for benign prostatic hyperplasia.

This study aimed to assess the clinical outcome and safety of holmium laser enucleation of the prostate (HoLEP) following transrectal ultrasound-guided prostate biopsy (TR biopsy) in the treatment of benign prostate hyperplasia. We retrospectively analyzed data from 556 patients who underwent HoLEP between 2014 and 2021. The patients were categorized into six groups: Group 1-A (n=45) underwent HoLEP within four months post TR biopsy. Group 1-B (n=94) underwent HoLEP more than four months post TR biopsy. Group 1-C (n=120) underwent HoLEP after a single TR biopsy. Group 1-D (n=19) underwent HoLEP after two or more TR biopsies. Group 1-total (n=139, group 1-A+group 1-B or group 1-C+group 1-D) underwent HoLEP post TR biopsy. Group 2 (control group, n=417) underwent HoLEP without prior TR biopsy. We examined perioperative parameters, safety, and functional outcomes. The age, body mass index, International Prostate Symptom Score (IPSS), uroflowmetry, and comorbid diseases between group 1-total and group 2 were comparable. However, group 1-total exhibited significantly elevated prostate-specific antigen levels and larger prostate volumes (p<0.01). Perioperative factors like enucleation time, enucleation weight, and catheterization duration were notably higher in group 1-total (p<0.01). All groups showed significant improvements in IPSS, postvoid residual urine, and maximum flow rate during the 1-year postoperative period (p<0.05). The rates of postoperative complications were similar between group 1-total and group 2. Enucleation time and catheterization duration were significantly longer in the TR biopsy group. However, postoperative complications were not significantly different between TR biopsy and non-TR biopsy groups.
