Abstract:

Urolithiasis remains a significant global health burden, with high recurrence rates following intervention. Ureteroscopy is increasingly preferred due to its safety and efficacy; however, recurrence after ureteroscopy is common and may be influenced by stone composition. This scoping review aims to explore the relationship between stone composition and recurrence rates post-ureteroscopy and to identify gaps in current evidence that could inform clinical practice and research. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines, we conducted a structured literature search (2014-2024) across PubMed, Scopus, MEDLINE, and Google Scholar. Studies were eligible if they reported on adult patients (>=18 years) undergoing ureteroscopy for renal or ureteric stones, provided stone composition data, and reported recurrence (defined radiologically, symptomatically, or via reintervention). Retrospective/prospective cohort studies, clinical trials, and case series (n >10) in English were included. Non-English, paediatric-only studies, case reports, and those lacking recurrence or composition data were excluded. In total, 13 studies met the inclusion criteria. Calcium oxalate was the most frequently reported stone type and appeared to be associated with higher recurrence rates. Reported recurrence ranged from 25.8% at 32 months to nearly 60% at 36 months, particularly in patients without metabolic follow-up. Reporting of uric acid, struvite, and cystine stones was inconsistent, limiting firm conclusions. The majority of studies were retrospective, small-scale, and lacked standardised definitions of recurrence, often conflating residual fragments with true recurrence. Language restriction and lack of granular metabolic data further limited synthesis. Stone composition appears to influence recurrence risk post-ureteroscopy, particularly for calcium-based stones. However, variability in study design, recurrence definitions, and underreporting of metabolic data reduce the strength of current evidence. Future prospective research with standardised reporting and broader linguistic inclusion is essential.

Abstract:
Introduction: The urology multidisciplinary team meeting (MDT) is the key weekly meeting that allows the opportunity to review results and discuss management plans for all urological cancers within a department. As populations age and cancer detection and management improve, the demand for the MDT will increase. We conducted a collaborative transregional study within the UK to evaluate the current workload on the urology MDT. Methods: The study was divided into two parts: a multicenter retrospective audit and a snapshot survey. Three UK hospitals in Birmingham, Liverpool, and Cardiff were recruited into the multicenter study. Each hospital provided full MDT lists for all weekly meetings between August 2017 and 2022. Retrospective data gathered included the number of patients discussed per week, the average age of patients per week, the time allocated to their weekly MDT, and the total number of consultants in the department. The second part of the study involved the distribution of an online questionnaire to urologists across the UK to obtain a snapshot picture with the above parameters. Results Snapshot data from 34 different UK hospitals showed MDT length ranged from 1-6 hours, patients discussed ranged from 10-90 per week, and the maximum average discussion time was 3.8 minutes per case. Furthermore, 76% (N = 28/37) of respondents said unnecessary cases were discussed. Varied suggestions were provided on how the MDT could be improved. Multicenter five-year data showed a rise in mean total numbers of patients discussed per week in all centers: a 34.8% increase in Birmingham (from 34.5 patients to 46.5 patients), a 23.5% increase in Liverpool (27.2 patients to 33.6 patients), and a 38.8% increase in Cardiff (22.7 patients to 31.5 patients). Hours per meeting were Birmingham (2), Liverpool (3), and Cardiff (4), which meant the average minutes per patient discussion were Birmingham (2.6), Liverpool (5.4), and Cardiff (7.6). Conclusion There is a rapidly rising trend across UK regions for the number of patients being discussed in the urology MDT meeting. The MDT structure and function across the country are highly variable. There is consensus that the MDT discusses cases that are unnecessary, and this has been recognized for many years. Widespread implementation of the latest MDT management guidelines is urgently required to ensure MDT meetings are able to function effectively and efficiently into the future.

Abstract:
The ureteral insertion of a silicone tube was first performed in 1967. A validated ureteral stent symptom questionnaire (USSQ) is used for an objective assessment of patient-reported stent-related symptoms. As the impact of stent diameter on the incidence of stent-related symptoms is unclear, we aimed to perform a systematic review and meta-analysis comparing USSQ reported outcomes when using a 6 Fr diameter ureteric stent, versus smaller diameter stents (4.7-5 Fr) when inserted for ureteric stones. All randomized control trials and comparative studies of 6 Fr versus 4.7-5 Fr ureteric stents were reviewed. The USSQ outcomes were considered as the primary outcome measures while stent migration was considered as a secondary outcome measure. A total of 61 articles were identified of which four studies met the eligibility criteria. There was a statistically significant association between the use of wider (6 Fr) diameter stents and the incidence of urinary symptoms as measured by the urinary index score. Larger stent diameters were associated with a statistically significant increase in the pain index score. There was no statistically significant difference in the scores between the compared stent diameters with regard to work performance score, general health index score, additional problems index score, and stent migration. There were insufficient reported outcomes to perform a meta-analysis of sexual matters index score. Our meta-analysis shows that using smaller diameter ureteric stents is associated with reduced urinary symptoms and patient-reported pain. Other USSQ parameter outcomes are statistically similar in the 6 Fr ureteric stent cohort versus the 4.7-5 Fr ureteric stent cohort. Our meta-analysis was limited due to the limited number of studies and gross heterogeneity of reporting parameters in various studies. We hope a large-scale homogeneous randomized control trial will further shed more insight into the stent symptoms response to stent diameter
