Establishing a national high fidelity cadaveric emergency urology simulation course to increase trainee preparedness for independent on-call practice: a prospective observational study
Background
Whilst competence in the management of a wide range of urological emergencies is a requirement for certification in urology, many conditions are uncommon and exposure during training may be limited. This prospective observational study sought to evaluate the feasibility and effectiveness of a standardised cadaveric emergency urology simulation course aimed at improving operative confidence and competence prior to independent on-call practice in the United Kingdom.
Methods
A two-day cadaveric emergency urology simulation course supported by the British Association of Urological Surgeons (BAUS) was implemented at two pilot centres. All delegates that undertook one of the initial series of courses were invited to complete online pre- and post-course questionnaires relating to prior operative experience, documented competence and perceived confidence in being able to perform specific emergency procedures independently. Primary outcome was a self-reported ‘confidence score’ selected from a linear numeric scale ranging from 1 (not at all confident to perform a given procedure independently) to 10 (fully confident). Statistical analysis was undertaken using SPSS Statistics for Mac Version 25 and the paired student’s t-test used to compare mean pre- and post-course scores.
Results
One hundred and four delegates undertook the course during the study period. Of these, 85 (81.7%) completed the pre-course survey and 67 (64.4%) completed the post-course survey, with 61 (58.7%) completing both. The greatest proportion of respondents were Speciality Trainees in Urology of ST5 level or higher (equivalent of Resident/Fellows with 4 or more years of surgical training; n = 31, 36.5%). Delegates reported variable pre-course exposure, with most experience reported in loin approach to the kidney (median 10) and least in exploration and packing of a transurethral resection cavity and emergency nephrectomy (median 0). Following course completion, a statistically significant increase in confidence score was observed for each procedure, with the greatest increases seen for shunt for priapism (4.87 to 8.80, p < 0.001), ureteric reimplantation (3.52 to 7.33, p < 0.001) and primary ureteric anastomosis (3.90 to 7.49, p < 0.001).
Conclusions
A standardised high fidelity cadaveric simulation course is feasible and significantly improves the confidence of trainees in performing a wide range of emergency procedures to which exposure is currently limited

Rationalising the use of investigation for urinary tract infections: Analysis of 700 patients and proposal for a diagnostic algorithm.
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 <55 years. Applying baseline imaging but confining cystoscopy to those aged ≥55 years and men with a confirmed history of rUTI would have saved 44% of procedures, missed no abnormalities with an overall diagnosis detection rate of 9.8% (69/700). This algorithm was validated in a separate cohort of 63 patients; applying it would have saved 46% (29/63) of cystoscopies with a positive diagnostic rate of 9.5% and no missed findings. CONCLUSION: To our knowledge this is one of the largest studies reporting the outcomes of investigations for UTI and rUTI. Our result suggests that imaging is a useful baseline assessment, but cystoscopy should be limited to specific subgroups. We propose and validate a simple decision algorithm to manage investigations for referrals for UTI in secondary care.N

Nomogram predicting the probability of spontaneous stone passage in patients presenting with acute ureteric colic.
OBJECTIVES: To develop a nomogram that could predict spontaneous stone passage (SSP) in patients presenting with acute ureteric colic who are suitable for conservative management. SUBJECT/PATIENTS: 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. METHODS: 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). RESULTS: 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 size >5-7mm (OR 0.2, 95%CI 0.16-0.25, p7mm (OR 0.11, 95%CI 0.08-0.15, p<0.001), 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, p<0.001) ), 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. CONCLUSION: 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
Improved Retinal Function in a Mouse Model of Dominant Retinitis Pigmentosa Following AAV-delivered Gene Therapy
Mutational heterogeneity represents one of the greatest barriers impeding the progress toward the clinic of gene therapies for many dominantly inherited disorders. A general strategy of gene suppression in conjunction with replacement has been proposed to overcome this mutational heterogeneity. In the current study, various aspects of this strategy are explored for a dominant form of the retinal degeneration, retinitis pigmentosa (RP), caused by mutations in the rhodopsin gene (RHO-adRP). While >200 mutations have been identified in rhodopsin (RHO), in principle, suppression and replacement may be employed to provide a single mutation-independent therapeutic for this form of the disorder. In the study we demonstrate in a transgenic mouse simulating human RHO-adRP that RNA interference–based suppression, together with gene replacement utilizing the endogenous mouse gene as the replacement, provides significant benefit as evaluated by electroretinography (ERG). Moreover, this is mirrored histologically by preservation of photoreceptors. AAV-based vectors were utilized for in vivo delivery of the therapy to the target cell type, the photoreceptors. The results demonstrate that RNAi-based mutation-independent suppression and replacement can provide benefit for RHO-adRP and promote the therapeutic approach as potentially beneficial for other autosomal dominantly inherited disorders
