To develop a nomogram that could predict spontaneous stone passage (SSP) in patients presenting with acute ureteric colic who are suitable for conservative management.A 2517 patient dataset was utilised from an international multi-centre cohort study (MIMIC, A Multi-centre Cohort Study Evaluating the role of Inflammatory Markers In Patients Presenting with Acute Ureteric Colic) of patients presenting with acute ureteric colic across 71 secondary care hospitals in the United Kingdom, Ireland, Australia, and New Zealand. Inclusion criteria mandated a non-contrast CT-KUB.SSP was defined as the 'absence of the need for intervention'. The model was developed using logistic regression and backwards selection (to achieve lowest AIC) in a subset from 2009-2015 (n=1728) and temporally validated on a subset from 2016-2017 (n=789).Of the 2517 patients, 1874 had SSP (74.5%). Mean age (±[SD]) was 47 (±14.7) years and 1892 were male (75.2%). At the end of the modelling process, gender: male (OR 0.8, 95%CI 0.64-1.01, p=0.07), neutrophil count (OR 1.03, 95%CI 1.00-1.06, p = 0.08), hydronephrosis (OR 0.79, 95%CI 0.59-1.05, p=0.1), hydroureter (OR 1.3, 95%CI 0.97-1.75, p =0.08), stone size5-7mm (OR 0.2, 95%CI 0.16-0.25, p0.0001), stone size7mm (OR 0.11, 95%CI 0.08-0.15, p0.001), middle ureter stone position (OR 0.59, 95%CI 0.43-0.81, p=0.001), upper ureter stone position (OR 0.31, 95%CI 0.25-0.39, p0.001) ), medical expulsive therapy use (OR 1.36, 95%CI 1.1 - 1.67, p = 0.001), oral NSAID use (OR 1.3, 95%CI 0.99 - 1.71, p=0.06), and rectal NSAID use (OR1.17, 95%CI 0.9 - 1.53, p=0.24) remained. Concordance-statistic (C-statistic) was 0.77 (95%CI 0.75 - 0.80) and a nomogram was developed based on these.The presented nomogram is available to use as an online calculator via www.BURSTurology.com and could allow clinicians and patients to make a more informed decision on pursuing conservative management versus early intervention.

AIMS: To evaluate the diagnostic yield of investigations performed on patients with a history of urinary tract infections (UTI). METHODS: A retrospective review was conducted on patients who underwent cystoscopy and imaging for a history of UTI between 2014 and 2019 in a single UK teaching hospital. Data were collected on demographics, cystoscopy and radiological findings requiring further management. The cohort was stratified by age, gender and a confirmed history of recurrent UTI (rUTI). The subsequent algorithm was re-tested in a second cohort to validate its use. RESULTS: Seven hundred patients were included in the primary analysis-427 female and 273 males. Three hundred and thirty-one met the criteria of rUTI. The median age was 64 years (18-97). Imaging abnormalities were equally frequent in men 6.3% (15/241) and women 8% (30/380) and the majority noted in patients aged ≥55 years, 30/45 (66.7%). Amongst those who did not meet the definition of rUTI, abnormal imaging was identified in 5%-7% regardless of age group and gender. Cystoscopy abnormalities (n = 24) were twice more likely in males, 5.5%(15/273) than females, 2%(9/427). About 88%(21/24) were identified in patients ≥55 years. There were no positive findings in women

INTRODUCTION AND OBJECTIVE:Renal colic is a common urological problem with a lifetime incidence of approximately 8-19% in males and 3-5% in females. The MIMIC Study was a 4171 patient cohort study ...

Objectives To analyse the results of the stress urinary incontinence (SUI) audit conducted by the British Association of Urological Surgeons (BAUS), and to present UK urologists' contemporary management of SUI. Patients and methods The BAUS audit tool is an online resource, to which all UK urologists performing procedures for SUI are invited to submit data. The data entries for procedures performed during 2014-2016 were collated and analysed. Results Over the 3-year period analysed, 2917 procedures were reported by 109 surgeons, with a median of 20 procedures reported per surgeon. A total of 2 366 procedures (81.1%) were recorded as a primary surgery, with 548 procedures (18.8%) performed for recurrent SUI. Within the time period analysed, changes were noted in the frequency of all procedures performed, with a trend towards a reduction in the use of synthetic mid-urethral tapes, and a commensurate increase in the use of urethral bulking agents and autologous fascial slings. A total of 107 (3.9% of patients) peri-operative complications were recorded, with no association identified with patient age, BMI or surgeon volume. Follow-up data were available on 1832 patients (62.8%) at a median of 100 days postoperatively. Reduced pad use was reported in 1311 of patients (84.5%) with follow-up data available and 86.3% reported a pad use of one or less per day. In all, 375 patients (85%) reported being satisfied or very satisfied with the outcome of their procedure at follow-up, although data entry for this domain was poor. De novo overactive bladder (OAB) symptoms were reported by 15.2% of patients (263/1727), and this was the most commonly reported postoperative complication. For those reporting pre-existing OAB prior to their SUI surgery, 28.7% (307/1069) of patients reported they got better after their procedure, whilst 61.9% (662/1069) of patients reported no change and 9.4% of patients (100/1 069) got worse. Conclusions This review identified that, despite urological surgeons undertaking a relatively low volume of procedures per year, SUI surgery by UK urologists is associated with excellent short-term surgeon- and patient-reported outcomes and low numbers of low grade complications. Complications do not appear to be associated with surgeon volume, nor do they appear higher in those undergoing mesh surgery. Shortfalls in data collection have been identified, and a longer follow-up period is required to comment adequately on long-term complications, such as chronic pain and tape extrusion/erosion rates.

We aim to provide a general overview of the available UK and European guidelines on non-oncological causes of chronic pelvic pain, and highlight any differences in practice. We have reviewed the current guidelines on chronic pelvic pain syndrome (defined as chronic pelvic pain with no identified underlying cause and/or the pain is non-specific or involves more than one organ) and other specific organ pain syndromes particularly relevant to urological clinical practice, including prostate pain syndrome, bladder pain syndrome and gynaecological causes of chronic pelvic pain. We have identified a relative paucity of UK guidelines, and accept that the European Association of Urology provides a comprehensive and current evidence based reference and guide which is utilised and regarded by most urologists as the ‘gold standard’ in UK practice.

To assess the relationship of white blood cell count (WBC) and other routinely collected inflammatory and clinical markers including stone size, stone position, and medical expulsive therapy use (MET), with spontaneous stone passage (SSP) in a large contemporary cohort of patients with acute ureteric colic, as there are conflicting data on the role of WBC and other inflammatory markers in SSP in patients with acute ureteric colic.Multicentre retrospective cohort study coordinated by the British Urology Researchers in Surgical Training (BURST) Research Collaborative at 71 secondary care hospitals across four countries (UK, Republic of Ireland, Australia, and New Zealand). In all, 4170 patients presented with acute ureteric colic and a computed tomography confirmed single ureteric stone. Our primary outcome measure was SSP, as defined by the absence of need for intervention to assist stone passage (SP). Multivariable mixed effects logistic regression was used to explore the relationship between key patient factors and SSP.In all, 2518 patients were discharged with conservative management and had further follow-up with a SSP rate of 74% (n = 1874/2518). Sepsis after discharge with conservative management was reported in 0.6% (n = 16/2518). On multivariable analysis neither WBC, neutrophils count, nor C-reactive protein (CRP) predicted SSP, with an adjusted odds ratio (OR) of 0.97 (95% confidence interval [CI] 0.91-1.04, P = 0.38), 1.06 (95% CI 0.99-1.13, P = 0.1) and 1.00 (95% CI 0.99-1.00, P = 0.17), respectively. MET also did not predict SSP (adjusted OR 1.11, 95% CI 0.76-1.61). However, stone size and stone position were significant predictors. SSP for stones5 mm was 89% (95% CI 87-90) compared to 49% (95% CI 44-53) for stones ≥5-7 mm, and 29% (95% CI 23-36) for stones7 mm. For stones in the upper ureter the SSP rate was 52% (95% CI 48-56), middle ureter was 70% (95% CI 64-76), and lower ureter was 83% (95% CI 81-85).In contrast to the previously published literature, we found that in patients with acute ureteric colic who are discharged with initial conservative management neither WBC, neutrophil count, nor CRP, helps determine the likelihood of SSP. We also found no overall benefit from the use of MET. Stone size and position are important predictors and our present findings represent the most comprehensive SP rates for each millimetre increase in stone size from a large contemporary cohort adjusting for key potential confounders. We anticipate that these data will aid clinicians managing patients with acute ureteric colic and help guide management decisions and the need for intervention.

The field of liver transplantation is limited by the availability of donor organs. The use of living donor and split cadaveric grafts is one potential method of expanding the donor pool. However, primary graft dysfunction can result from the use of partial livers despite the absence of other causes such as vascular obstruction or sepsis. This increasingly recognised phenomenon is termed “Small-for-size syndrome” (SFSS). Studies in animal models and humans have suggested portal hyperperfusion of the graft combined with poor venous outflow and reduced arterial flow might cause sinusoidal congestion and endothelial dysfunction. Graft related factors such as graft to recipient body weight ratio < 0.8, impaired venous outflow, steatosis > 30% and prolonged warm/cold ischemia time are positively predictive of SFSS. Donor related factors include deranged liver function tests and prolonged intensive care unit stay greater than five days. Child-Pugh grade C recipients are at relatively greater risk of developing SFSS. Surgical approaches to prevent SFSS fall into two categories: those targeting portal hyperperfusion by reducing inflow to the graft, including splenic artery modulation and portacaval shunts; and those aiming to relieve parenchymal congestion. This review aims to examine the controversial diagnosis of SFSS, including current strategies to predict and prevent its occurrence. We will also consider whether such interventions could jeopardize the graft by compromising regeneration.
