Adverse events related to laser fibers and laser machines during ureteroscopy and stone lithotripsy: Insights from an updated 10-year analysis of the US MAUDE database.

INTRODUCTION: Ureteroscopy has become increasingly chosen as a treatment of choice for patients with kidney stone disease and laser as the energy source for stone lithotripsy is a key part of this. Our aim was to analyse a national database to evaluate the burden of adverse events related to laser fibers and laser machines. METHODS: Search was performed of the Manufacturer User and Facility Device Experience (MAUDE) database in the United States for all events related to holmium laser fibers and holmium laser machines during ureteroscopy between 2012-2021. Information collected included the following: problem, timing, prolonged anaesthesia, early termination of procedure, injury and retained parts. RESULTS: 699 holmium laser fiber events were reported and these had been manufactured by 13 different companies. The commonest problems were breakage outside the patient while in use (26.3%) and breakage of the laser fiber tip (21.2%). Manufacturers concluded root cause to be device failure in 8.9%. 29% of issues occurred before the laser had been activated. 5.2% of cases had to be cancelled as a result of an event. Significantly more injuries were sustained intra-operatively by operating staff compared to patients (6% vs. 0.2%, p < 0.001). All these injuries were superficial burns to the skin with the hand being the most affected body part (88.1%). Zero ocular injuries were reported. Only eight events were related to laser machines and all involved sudden hardware failure but no patient injury. CONCLUSIONS: Laser fibers are fragile. Most adverse events are due to operator error. Direct patient injury from laser fiber is scarce but operating staff should be aware of the risk of sustaining minor burns. Laser machines rarely incur problems and, in this study, did not result in any safety issues beyond need to abort the procedure due to lack of spare equipment.

First clinical evaluation of a flexible digital ureteroscope with direct in scope suctioning system (Pusen DISS 7.5Ch): prospective multicentric feasibility study.

PURPOSE: A new digital single-use flexible ureteroscope, Pusen direct in scope suction (DISS) 7.5Fr (PU3033AH), was evaluated with respect to manoeuvrability, suction quality, visibility and clinical efficiency. METHODS: A prospective cohort study was conducted in six tertiary reference centers in Europe and Asia between February-April 2024. Adult patients who underwent flexible ureteroscopy and laser lithotripsy (fURSL) for urolithiasis were included. Demographic, intraoperative and follow-up characteristics were recorded. Quality parameters were rated by each surgeon using a Likert scale. RESULTS: a total of 57 fURSL were performed. Preoperative characteristics revealed a mean stone volume of 480.00mm3 (mean Hounsfield Unit- 998). 57.9%(n = 33) of the patients were pre-stented, and a ureteric access sheath was used in 64.9%(n = 37). Integrated-suction was deemed helpful in 94.7%(n = 54) fURSL as reported by the operators. An initial stone free rate (SFR) confirmed by postoperative imaging was achieved in 84.21%(n = 48). Quality parameters of the scope reached a mean Likert score of 4.5, with a "very good" mean evaluation for "scope placement", "visual quality", "irrigation", "deflection", "manoeuvrability", and "weight". "Suction quality" and "overall performance satisfaction" were rated "good". Comparing the Pusen DISS scope with other previously used scopes, overall satisfaction was rated 4.1. When asked if the surgeons would be willing to use the Pusen DISS 7.5Fr scope in the future, all the six surgeons answered positively. CONCLUSION: The DISS 7.5 Pusen ureteroscope displayed good visibility, manoeuvrability and suction quality, with excellent operative results. Further evaluation with larger comparative cohorts will help understand the potential of in-vivo use of integrated suctioning systems for fURSL.

Trends of European School of Urology (ESU) training and resident education: an overview of 2 decades of EAU education programme.

BACKGROUND: Over the last 2 decades, various education and training programmes have been launched by the European School of Urology (ESU) on behalf of the European Association of Urology (EAU) Education Office. These include e-learning platforms, in-person meetings, courses, podcasts, webinars, sub-specialisation meetings and the European Urology Resident Education Programme (EUREP), all of which aim to achieve standardisation in urological education (SISE) and training at the highest level. METHODS: Data from the last 2 decades of all ESU activities were collected by the EAU/ESU office and analyzed for attendance, geographical, gender and age trends. Demographic data on registrations and attendances at EUREP were also monitored and analysed. A descriptive analysis of participation and trends is provided. RESULTS: A total of 4750 participants have completed ESU courses (including guideline courses, specialization courses and webinar courses). Similarly, a total of 5958 trainees attended the EUREP from 2004 to 2022 of which the male: female ratio was 3.75:1. However, the proportion of females increased 3.5-fold from 10.7% in 2004 to 37.1% in 2022(p < 0.001). There is a growing interest in the meeting, with increasing registrations over this time (353 in 2004 to 599 in 2023, p < 0.001). The mean age of participants is constantly decreasing (32.6 years in 2004 to 31.54 in 2022), with a mean yearly decrease of -0.18% (p < 0.001). CONCLUSION: ESU courses have had increasing interest and participation from young urologists worldwide. During EUREP, while the trainee age has decreased, there has been a surge in the proportion of female trainees. ESU is providing all modes of education and training across the world with both virtual and in-person meetings and courses, which would help in the development and preparation of urologists of the future and provide the best patient care.

Urology Malpractice Litigation and Complaints Referred to the General Medical Council: A UK-based analysis of Trends, Demographics, and Outcomes over the Last Two Decades.

BACKGROUND AND OBJECTIVE: Surgical specialties account for a significant proportion of malpractice litigation claims and complaints to the regulatory body. The aim of our study was to analyse trends and outcomes for urology malpractice claims and complaints to the General Medical Council (GMC) in the UK over the last two decades. METHODS: Data were requested from the GMC and NHS Resolution under the Freedom of Information Act 2000. This included the number of malpractice claims in urology, including damages paid, and annual complaints about urologists to the GMC since 2006. For complaints to the GMC, demographics, case outcomes, and reasons for complaints were also provided. KEY FINDINGS AND LIMITATIONS: Over the study period, there was a 2.9-fold increase in successful (settled or closed) malpractice claims (from 2006-2007 to 2022-2023) and a 1.5-fold increase in complaints to the GMC about urologists (from 2007 to 2024). There were 2511 successful malpractice claims, resulting in a total payout of £145 million. The GMC received 1118 complaints regarding 1045 urologists, of which 26.0% (291/1118) were investigated, 2.4% (27/1118) resulted in a hearing, and 0.5% (6/1118) resulted in the doctor involved being erased from the medical register. Demographic distributions, including gender, ethnicity, and place of medical qualification, for the group involved in complaints differed significantly in comparison to the overall urologist population. CONCLUSIONS AND CLINICAL IMPLICATIONS: The numbers of successful urological malpractice claims and complaints to the regulatory body and associated costs have risen. A small proportion of complaints to the GMC led to a medicolegal hearing and subsequent erasure of the doctors involved from the medical register. PATIENT SUMMARY: We analysed trends and outcomes for malpractice claims and complaints in urology over the last two decades in the UK. The numbers of successful urological malpractice claims and complaints and associated costs have risen, with a small proportion of doctors removed from the medical register.

Gender Demographics in Urology in Europe: Trend Analysis over a 10-year Period.

BACKGROUND AND OBJECTIVE: We analysed gender trends for urology trainees and consultants across nine European countries (Spain, UK, Netherlands, Norway, Germany, France, Belgium, Italy, and Switzerland) over a 10-yr period (2012-2022) to gain insight into gender dynamics in urology and determine if there is increasing representation of women in the profession. This information will help in the development of more effective strategies to promote gender equality. METHODS: Data from the past decade were collected, encompassing trainee and consultant records nationally. The project focused on gender demographics within the field of urology, looking at trends in the nine countries. Information was obtained from national registries and supplemented with additional data sources where necessary. KEY FINDINGS AND LIMITATIONS: Our results reveal significant variations in gender composition of urology trainees, displaying a slight increase in the presence of female trainees across most countries. This trend was particularly remarkable in Spain and Belgium where the proportion of female urologists exceeded 50%, indicating a potential generational shift within the field. Furthermore, among consultants, there was a global annual increase of 6.7% in female representation, with notable rises in the UK, France, Swiss and Belgium. These trends were also reflected in the membership affiliation data of the European Association of Urology during the same timeframe. CONCLUSIONS AND CLINICAL IMPLICATIONS: The observed growth in female trainees and consultants offers valuable insights for educational and workforce planning. It is important to understand the evolving dynamics in the field of urology, especially for trainee demographics. Furthermore, the potential engagement of this with more countries could provide a comprehensive view of urology trends across Europe and worldwide. PATIENT SUMMARY: We looked at the proportion of urology trainees and consultants who are women across Europe. We found that overall, the percentage of females in these roles increased from 2012 to 2022, especially for urology trainees, but there are differences by country. Even if these trends continue, it will take many years before there is equal representation of men and women doctors in urology.

International Alliance of Urolithiasis (IAU) consensus on miniaturized percutaneous nephrolithotomy.

Over the past three decades, there has been increasing interest in miniaturized percutaneous nephrolithotomy (mPCNL) techniques featuring smaller tracts as they offer potential solutions to mitigate complications associated with standard PCNL (sPCNL). However, despite this growing acceptance and recognition of its benefits, unresolved controversies and acknowledged limitations continue to impede widespread adoption due to a lack of consensus on optimal perioperative management strategies and procedural tips and tricks. In response to these challenges, an international panel comprising experts from the International Alliance of Urolithiasis (IAU) took on the task of compiling an expert consensus document on mPCNL procedures aimed at providing urologists with a comprehensive clinical framework for practice. This endeavor involved conducting a systematic literature review to identify research gaps (RGs), which formed the foundation for developing a structured questionnaire survey. Subsequently, a two-round modified Delphi survey was implemented, culminating in a group meeting to generate final evidence-based comments. All 64 experts completed the second-round survey, resulting in a response rate of 100.0%. Fifty-eight key questions were raised focusing on mPCNLs within 4 main domains, including general information (13 questions), preoperative work-up (13 questions), procedural tips and tricks (19 questions), and postoperative evaluation and follow-up (13 questions). Additionally, 9 questions evaluated the experts' experience with PCNLs. Consensus was reached on 30 questions after the second-round survey, while professional statements for the remaining 28 key questions were provided after discussion in an online panel meeting. mPCNL, characterized by a tract smaller than 18 Fr and an innovative lithotripsy technique, has firmly established itself as a viable and effective approach for managing upper urinary tract stones in both adults and pediatrics. It offers several advantages over sPCNL including reduced bleeding, fewer requirements for nephrostomy tubes, decreased pain, and shorter hospital stays. The series of detailed techniques presented here serve as a comprehensive guide for urologists, aiming to improve their procedural understanding and optimize patient outcomes.

A systematic review of robot-assisted simple prostatectomy outcomes by prostate volume.

PURPOSE: The aim of our study is to assess the differences in functional outcomes during the perioperative and postoperative period after RASP depending on BPH volume. METHODS: We searched 2 databases: MEDLINE (PubMed) and Google Scholar using the following search query: robot* AND "simple prostatectomy". The search strategy and review protocol are available at Prospero (CRD42024508071). RESULTS: We included 25 articles published between 2008 and 2023. Preoperatively, patients with prostate size < 100 cm3 had more severe symptoms while postoperatively all of them had only mild lower urinary tract symptoms (LUTS). In larger BPH, two authors reported moderate LUTS after RASP: Fuschi [1] (mean IPSS 8.09 ± 2.41) and Stolzenburg [2] (mean IPSS 8 ± 2.7). Postoperative Qmax was also noticeably higher in smaller BPH (mean value range 28.5-55.5 ml/s) compared to larger BPH (mean Qmax 18-29.6 ml/s), although in both groups it was within the normal range. Postoperative post-void residual (PVR) was normal as well except in one study by Stolzenburg et al. [2]. Blood loss was comparable between the groups. The complications rate in general was low. CONCLUSION: RASP is effective in terms of subjective and objective urination indicators, and a safe procedure for BPH. In the lack of data on implementation of RASP in small prostate volumes, this procedure can be seen as an upper size «limitless¼ treatment alternative. Currently, comparative data regarding prostate volume is lacking, and future trials with subgroups analysis related to BPH volume might help to address this issue.

Ureteroscopy and lasertripsy for lower pole stones <2 cm, in situ vs displacement? A systematic review and meta-analysis.

OBJECTIVE: To investigate the outcomes of ureteroscopy and lasertripsy in lower pole renal stones <2 cm when treated in situ compared to displacement to the upper pole. PATIENTS AND METHODS: Using the Medical Literature Analysis and Retrieval System Online (MEDLINE)/PubMed, the Excerpta Medica dataBASE (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Library, and Clinicaltrials.gov we identified adult population, English language, studies published until March 2023 comparing surgical outcomes and stone-free rates (SFRs) in relation to lower pole stones <2 cm managed in situ vs those displaced (International Prospective Register of Systematic Reviews [PROSPERO] identifier: CRD42023432750). Analysis was performed using R with the 'meta' package. Bias analysis was performed using the Cochrane Risk of Bias 2 tool for randomised trials and the Newcastle-Ottawa scale for observational studies. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach was used to ascertain the certainty of evidence. RESULTS: A total of five studies were included, comprising two retrospective cohort studies, three randomised trials, with a total of 408 patients. Meta-analysis demonstrated SFRs are significantly higher in those patients undergoing displacement vs those managed in situ (risk ratio 1.21, 95% confidence interval [CI] 1.10-1.34, P < 0.001). There was no significant difference in complication rates. Operative time was significantly longer in the displacement group (mean difference 5.62 min, 95% CI 0.40-10.83 min; P = 0.03). Overall risk of bias was moderate. Certainty of evidence was moderate for stone-free status, and very low for all other outcomes. CONCLUSIONS: This systematic review and meta-analysis demonstrates that for lower pole stones <2 cm displacement strategies have significantly higher SFRs than treatment in situ, with no significant difference in complications. There is significantly increased operative time in the displaced group, but an additional 6 min is unlikely to be clinically significant.

Suction use in ureterorenoscopy: A systematic review and meta-analysis of comparative studies.

Objectives: Ureterorenoscopy is seeing a bloom of technological advances, one of which is incorporating suction. The objective of this study is to systematically review existing literature regarding suction use in rigid and flexible ureterorenoscopy and perform meta-analysis of studies comparing suction versus no suction ureteroscopy or mini percutaneous nephrolithotomy (PCNL). Methods: A literature search was performed (November 2023) in MEDLINE, Embase and Cochrane CENTRAL. Study protocol was registered at PROSPERO (CRD42023482360). Comparative studies (observational and randomized) were eligible for inclusion if they compared suction versus no suction group and reported at least one primary outcome of interest (stone-free or complication rate). Results: Sixteen studies (5 randomized and 11 observational), analysing 1086 and 1109 patients in standard and suction groups, respectively, were included. Final stone-free rates (SFRs), overall and infectious complications and length of hospital stay exhibited significant improvement when suction was used. When mini-PCNL was compared with flexible ureterorenoscopy with suction, no differences were found in terms of stone-free and infectious complications rates. Conclusions: Ureterorenoscopy is a commonly performed endoscopic procedure for urolithiasis treatment, the success of which is defined by SFRs and complication rates. Application of suction via ureteral access sheaths, ureteral catheters or scopes may provide improved SFRs, reduced overall and infectious complication rates, along with a reduction in length of hospital stay. Further randomized studies are needed to validate these findings and standardize indications and protocols.

Operative outcomes 24 hours after retrograde intrarenal surgery for solitary renal calculi using a flexible and navigable suction ureteral access sheath. A prospective global multicenter study by the European Association of Urology Section on Urolithiasis.

BACKGROUND: Suction techniques showed potential to improve outcomes of retrograde intra-renal surgery (RIRS). We assessed the 24-hour stone-free rate (SFR) and complications after RIRS using flexible and navigable suction ureteral access sheaths (FANS-UAS). METHODS: Sixteen centers prospectively contributed to data (August 2023-October 2023). Inclusion criteria: age ≥18 years, single renal stone, pre and 24-hour post-RIRS CT scan. Exclusion criteria were: ureteral stone, anomalous kidney, multiple stones. SFR was divided into: 1) grade A - no fragments; 2) grade B - fragments ≤2 mm; 3) grade C - fragments 2.1-4 mm; and 4) grade D - fragments >4 mm. A multivariable logistic regression analysis model was performed to assess factors associated with the odds of having grade A stone-free status. Data are expressed as median (interquartile range), absolute numbers and frequencies, odds ratio (OR), and 95% confidence interval (CI). RESULTS: One hundred forty-two patients with a median age of 52 years (40-61) were enrolled. 61.3% were males. Median stone volume was 1165 mm3 (656-1936). Median operative time was 48.5 (36.25-71.75) min. Transient fever (37°C-37.5°C) occurred in 10 (7%) patients. No sepsis case occurred. 96.5% of patients were stone-free (Grade A+B). Grade A SFR was 52.8%. All patients were discharged within 48 hours. Bone window (OR 3.156 95% CI 1.177-9.130, P=0.027) was the only factor significantly associated with higher odds of 100% SFR, while stone volume (OR 0.999, 95% CI 0.999-1.000, P=0.007) was significantly associated with lower odds. CONCLUSIONS: Imaging and clinical evidence demonstrate excellent perioperative outcomes just 24 hours post RIRS with FANS-UAS. The technique demonstrates a good safety profile, ability for immediate high SFR, and a low rate of infective complications.

Comparing thulium fiber versus high power holmium laser in bilateral same sitting retrograde intrarenal surgery for kidney stones: Results from a multicenter study.

PURPOSE: Traditionally, bilateral urolithiasis treatment involved staged interventions due to safety concerns. Recent studies have shown that same-sitting bilateral retrograde intrarenal surgery (SSB-RIRS) is effective, with acceptable complication rates. However, there's no clear data on the optimum laser for the procedure. This study aimed to assess outcomes of SSB-RIRS comparing thulium fiber laser (TFL) and high-power holmium:yttrium-aluminum-garnet (Ho:YAG) laser in a multicenter real-world practice. MATERIALS AND METHODS: Retrospective analysis was conducted on patients undergoing SSB-RIRS from January 2015 to June 2022 across 21 centers worldwide. Three months perioperative and postoperative outcomes were recorded, focusing on complications and stone-free rates (SFR). RESULTS: A total of 733 patients were included, with 415 in group 1 (Ho:YAG) and 318 in group 2 (TFL). Both groups have similar demographic and stone characteristics. Group 1 had more incidence of symptomatic pain or hematuria (26.5% vs. 10.4%). Operation and lasing times were comparable. The use of baskets was higher in group 1 (47.2% vs. 18.9%, p<0.001). Postoperative complications and length of hospital stay were similar. Group 2 had a higher overall SFR. Multivariate regression analysis indicated that age, presence of stone at the lower pole, and stone diameter were associated with lower odds of being stone-free bilaterally, while TFL was associated with higher odds. CONCLUSIONS: Our study shows that urologists use both lasers equally for SSB-RIRS. Reintervention rates are low, safety profiles are comparable, and single-stage bilateral SFR may be better in certain cases. Bilateral lower pole and large-volume stones have higher chances of residual fragments.

Association and risk of metabolic syndrome and kidney stone disease: outcomes from a systematic review and meta-analysis.

PURPOSE OF REVIEW: Metabolic syndrome (MetS) has emerged as a potential contributor to the development of kidney stone disease (KSD). This study aims to conduct a systematic review of the literature, and meta-analysis of the association between MetS and KSD. RECENT FINDINGS: Systematic review revealed Fifteen articles (433 201 patients) were eligible for analysis. Meta-analysis of 11 studies identified a statistically significant association between MetS and KSD with unadjusted odds ratio of 2.02 [95% confidence interval (CI) 1.96-2.08, P < 0.001], and pooled adjusted odds ratio of 1.22 [95% CI 1.09-1.37, P < 0.001]. Of the different MetS traits, hypertension and impaired glucose tolerance were the most significantly associated with KSD. SUMMARY: This study confirms a significant association between MetS and KSD. Despite variations in MetS definitions across different studies analysed, consistent associations were observed across studies. This may have clinical implications in that guidelines do not currently recommend routine MetS screening in KSD patients.

International Alliance of Urolithiasis (IAU) guidelines on the management of pediatric urolithiasis.

The aim of this study was to construct the sixth in a series of guidelines on the treatment of urolithiasis by the International Alliance of Urolithiasis (IAU) that by providing a clinical framework for the management of pediatric patients with urolithiasis based on the best available published literature. All recommendations were summarized following a systematic review and assessment of literature in the PubMed database from January 1952 to December 2023. Each generated recommendation was graded using a modified GRADE methodology. Recommendations are agreed upon by Panel Members following review and discussion of the evidence. Guideline recommendations were developed that addressed the following topics: etiology, risk factors, clinical presentation and symptoms, diagnosis, conservative management, surgical interventions, prevention, and follow-up. Similarities in the treatment of primary stone episodes between children and adults, incorporating conservative management and advancements in technology for less invasive stone removal, are evident. Additionally, preventive strategies aiming to reduce recurrence rates, such as ensuring sufficient fluid intake, establishing well-planned dietary adjustments, and selective use pharmacologic therapies will also result in highly successful outcomes in pediatric stone patients. Depending on the severity of metabolic disorders and also anatomical abnormalities, a careful and close follow-up program should inevitably be planned in each pediatric patient to limit the risk of future recurrence rates.

ChatGPT in Clinical Medicine, Urology and Academia: A Review.

BACKGROUND: This study aims to provide a comprehensive overview of the current literature on the utilisation of ChatGPT in the fields of clinical medicine, urology, and academic medicine, while also addressing the associated ethical challenges and potential risks. METHODS: This narrative review conducted an extensive search of the PubMed and MEDLINE databases, covering the period from January 2022 to January 2024. The search phrases employed were "urologic surgery" in conjunction with "artificial intelligence", "machine learning", "neural network", "ChatGPT", "urology", and "medicine". The initial studies were chosen from the screened research to examine the possible interaction between those entities. Research utilising animal models was excluded. RESULTS: ChatGPT has demonstrated its usefulness in clinical settings by producing precise clinical correspondence, discharge summaries, and medical records, thereby assisting in these laborious tasks, especially with the latest iterations of ChatGPT. Furthermore, patients can access essential medical information by inquiring with ChatGPT. Nevertheless, there are multiple concerns regarding the correctness of the system, including allegations of falsified data and references. These issues emphasise the importance of having a doctor oversee the final result to guarantee patient safety. ChatGPT shows potential in academic medicine for generating drafts and organising datasets. However, the presence of guidelines and plagiarism-detection technologies is necessary to mitigate the risks of plagiarism and the use of faked data when using it for academic purposes. CONCLUSIONS: ChatGPT should be utilised as a supplementary tool by urologists and academicians. However, it is now advisable to have human oversight to guarantee patient safety, uphold academic integrity, and maintain transparency.

Transurethral resection and other minimally invasive treatment options for BPH: would we treat ourselves as we treat our patients? Results from EAU Section of Uro-Technology (ESUT) decision-making survey among urologists.

Introduction: With the introduction of novel treatment options for benign prostatic hyperplasia (BPH), decision making regarding surgical management has become ever more complex. Factors such as clinical exposure, equipment availability, patient characteristics and hospital setting may affect what treatment is offered and an informed patient choice. The aim of this study was to investigate how urologists help patients make decisions regarding BPH management and whether their practice would differ if they were the patient themselves. Material and methods: A 52-question survey presenting hypothetical clinical scenarios was distributed to European urologists and trainees/residents online and in person. In each scenario, regarding treatment options for BPH, the participant considered themselves firstly as the treating clinician and secondly as the patient themselves. Details regarding the participants' clinical experience, awareness of treatment options and exposure to these options were obtained. Results: There were 139 participants; 69.8% of whom were consultants, with 82.1% of participants having practiced urology for more than 5 years. A total of 59.7% of urologists consider themselves BPH specialists. Furthermore, 93.5% of those surveyed had performed transurethral resection of the prostate (TURP), whilst procedures performed the least by participants were minimally invasive surgical therapy (MIST) options. Only 17.3% had seen and 1.4% had performed all of the treatment options. When considering themselves as a patient within standard practice, there was a preference for HoLEP amongst participants. Conclusions: The majority of urologists surveyed had minimal experience to newer BPH techniques and MIST, suggesting that more exposure is required. A higher rate of HoLEP was chosen as a treatment option for urologists themselves as a patient than what they would choose as an option for their patients.

Variability in Profiles and Prevalences of Gram-Negative Bacteria in Urinary Tract Infections: A Population-Based Analysis.

Objective: An increase in antimicrobial resistance (AMR) is observed worldwide, partly due to the overuse and misuse of antibiotics, which are ineffective in certain population subgroups. This negatively impacts both the healthcare system and patients. Our study aimed to investigate the current AMR profiles for the most commonly used antibiotics in treating urinary tract infections (UTIs) caused by gram-negative bacteria (GNB) across different age and gender subpopulations. By doing so, we provide valuable information for doctors managing prophylactic and empiric therapeutic treatments. Materials and Methods: We retrospectively analysed over 650,000 urine cultures collected in the Microbiology Department of a referral university hospital in Southern England from January 2014 to December 2022. A population-based analysis for subgroups was performed to rule out differences in AMR patterns. Our report was recorded at UHS as an internal audit (UHS7670). Results: 146,867 cultures were found positive for GNB growth. Nitrofurantoin showed the best sensitivity patterns for all age subgroups (0.93% for patients aged ≤ 18; 1.22% for patients aged 19-40; 2.17% for patients aged 40-60; and 3.48% for patients aged > 60), regardless of gender (male: 6.37%, female: 2.59%). Ampicillin/amoxicillin and trimethoprim showed a poor AMR profile for all age groups (>55% and >28%, respectively) and genders (>60% and >28%, respectively). All the other tested antibiotics (cefalexin, cefotaxime, ceftazidime, ciprofloxacin, co-amoxiclav, gentamicin) showed an overall good profile for GNB resistance across all subgroups. For all antibiotics except trimethoprim, the risk of developing AMR was significantly higher in the male population. We also found that people aged over 60 had a higher risk of AMR compared to the other age groups for all antibiotics, with the exception of cefotaxime and co-amoxiclav. Conclusions: With an overall rise in resistance patterns for GNB-related UTIs, certain antibiotics-particularly ampicillin/amoxicillin and trimethoprim-now exhibit very poor sensitivity profiles. However, antibiotics such as nitrofurantoin and gentamicin remain excellent options for empirically treating UTIs. It is important to note that AMR can vary across different populations, with higher resistance often found in elderly and male patients. Clinicians must stay informed about current guidelines and research to provide the best treatment options while minimizing the risk of further AMR development.

Development of the European Laparoscopic Intermediate Urological Skills LUSs2 Curriculum: A Delphi Consensus from the European School of Urology.

Background and objective: While programmes such as the European Basic Laparoscopic Urological Skills have made strides in foundational training, a significant gap exists for intermediate and advanced laparoscopy education. Our objective is to develop and validate the European laparoscopic intermediate urological skills (LUSs2) curriculum, which will establish uniformity in the training of urological laparoscopic procedures and facilitate proficiency among practitioners. Methods: The study combines a literature review, cognitive task analysis development by a steering group, and a two-round Delphi survey involving international experts in urological laparoscopy. Consensus was defined as agreement of ≥70% among experts. The survey included statements on various laparoscopic procedures, assessed on a Likert scale from 1 (strongly disagree) to 9 (strongly agree). Key findings and limitations: The Delphi process achieved consensus on 85% (235/275) of statements, indicating a strong agreement on the curriculum's content. Areas covered include renal hilum dissection, major vessel injury management, enucleation and renorrhaphy, vesicourethral anastomosis, and pyeloplasty. Limitations include the nonsystematic nature of the literature review and potential biases inherent in expert-based consensus methods. Conclusions and clinical implications: The LUSs2 curriculum significantly advances the standardised training of laparoscopic urological skills. It offers a detailed, consensus-validated framework that addresses the need for uniformity in surgical education and aims to enhance surgical proficiency and patient care. Patient summary: This study presents the development of a new standardised training curriculum for urological laparoscopic surgery. We intend this curriculum to improve the quality of surgical training and ensure high-quality patient care.

ChatGPT as a Clinical Decision Maker for Urolithiasis: Compliance with the Current European Association of Urology Guidelines.

Background and objective: Generative artificial intelligence models are among the most promising and widely used tools used in health care. This review investigates GPT-4 answers to decision-making questions regarding the diagnosis and treatment of urolithiasis across several clinical settings and their correspondence to the current European Association of Urology (EAU) guidelines. Methods: In March 2024, the GPT-4 model was asked 11 questions, containing a brief description of a patient with urolithiasis. All questions were grouped according to urolithiasis care step: diagnosis, urgent care, scheduled intervention, and metaphylaxis. When responses were received, compliance with the current EAU guidelines was assessed by experienced urologists. Key findings and limitations: Although all responses were provided with information that corresponded to EAU guidelines, six of the 11 answers were associated with missed guideline-provided parts, and incorrect data were given in eight of the 11 answers. GPT-4 is relatively safe in the initial diagnostic flow of patients suspected of having stones within the urinary tract and during treatment planning; however, its understanding of all the nuances of metaphylaxis leaves much to be desired and is far from the dogma given in the EAU guidelines. Moreover, GPT-4 knowledge of strategy and algorithm is not always aligned with the EAU guidelines. Conclusions and clinical implications: Despite the fact that from the perspective of patients with urolithiasis, GPT-4 is capable of answering their questions well, the specificity of questions from urologists is labor intensive for its current version, and necessitates the ability to interpret it correctly and further attempts to improve it. While some aspects of diagnostics are more accurate, these struggle with surgical planning and algorithms in line with the EAU guidelines. Patient summary: The generative artificial intelligence (AI) model GPT-4 is capable of answering urology-related questions, but lacks detailed responses. Although some aspects of the diagnostics are accurate, knowledge of surgical planning is not in line with the European Association of Urology guidelines. Future improvements should focus on efforts to enhance the accuracy, reliability, and clinical relevance of AI tools in urology.
