Introduction: Male urethral stricture affects 100 in 100,000 men. These are investigated using uroflowmetry, retrograde urethrography and cystourethroscopy. Management is usually endoscopic with urethral dilation or direct visual internal urethrotomy, although they have high failure rates.

Article Synopsis
  • - Cystectomy is the preferred treatment for muscle-invasive bladder cancer, with robotic cystectomy gaining popularity due to benefits like quicker recovery, less blood loss, and reduced pain.
  • - The study reviewed the incidence of uretero-enteric strictures (UES) in different cystectomy techniques (open, robotic with extracorporeal diversion, and robotic with intracorporeal diversion) and found open surgery had the lowest stricture rate (9.6%).
  • - While robotic techniques showed higher UES rates, they may involve a learning curve, prompting a need for further research and Randomized Control Trials (RCTs) to compare the effectiveness and safety of surgical options.

Introduction: It is challenging to perform prostate biopsy in men with suspicion of prostate malignancy without a rectum to facilitate prostate biopsy. Nevertheless, such patients are presenting at an earlier stage, due to increased PSA testing in association with improved MRI imaging. We describe a novel technique for prostate biopsy in two such cases.

Unlabelled: Reducing emergency room (ER) use may indicate the improved quality of patient care at index hospitalization. The aim of this study is to determine whether the use of near-infrared fluorescence (NIRF) imaging with indocyanine green (ICG) during coronary artery bypass grafting (CABG) surgery is associated with a lowered 90-day all-cause ER use.

Materials And Methods: This retrospective cohort study included adult patients with inpatient hospitalizations between January 2016 and June 2020 for an isolated CABG procedure at a US hospital.

Background: The purpose of this study is to assess which minimally invasive colon surgery approach may be associated with the least 30- and 90-day inpatient readmission costs from a payer perspective.

Methods: This retrospective claims analysis included adult Medicare and commercially insured beneficiaries who underwent minimally invasive sigmoid, left, or right colon surgery between January 2016 and December 2019. Two cohorts were created based on the use of near-infrared fluorescence (NIF) and were propensity-score matched 1 NIF:5 NoNIF.

Background: As part of 'The Hub' project at Wellcome Collection, a team of eight co-researchers with learning disabilities alongside academics created an online survey to challenge public understanding of learning disabilities. Using creative and arts-based methods, co-researchers remotely co-analysed the survey results amid Covid-19 lockdown challenges. Here, we explore our unexpected 'transition' journey from the physical 'Hub' to the digital space.

Through a process of robust co-design, we created a bespoke accessible survey platform to explore the role of co-researchers with learning disabilities (LDs) in research design and analysis. A team of co-researchers used this system to create an online survey to challenge public understanding of LDs [3]. Here, we describe and evaluate the process of remotely co-analyzing the survey data across 30 meetings in a research team consisting of academics and non-academics with diverse abilities amid new COVID-19 lockdown challenges.

Background: Informed consent is an integral part of the process prior to any surgical procedure [1]. Flexible cystoscopy is a common day case urological procedure and it is the gold standard investigation for visible haematuria [2].

Aim: To assess if postal consent is a suitable form of gaining informed consent for flexible cystoscopy.

Background: The COVID-19 pandemic has seen a change in the numbers of patients presenting to the emergency department (ED) with non-COVID symptoms, resulting in delayed presentations of many medical and surgical conditions.

Aims: To examine the impact of COVID-19 on acute urolithiasis presentations to the ED.

Methods: In this retrospective, single-centre, observational study, we reviewed all CT KUBs (and their corresponding cases) ordered in ED for possible acute urolithiasis in a 100-day period immediately prior to COVID-19 and in a 100-day period immediately afterwards.

Objective: Rezum technology uses heat from radiofrequency-generated water vapour to ablate prostate tissue. We evaluate the introduction of this thermal therapy to an Irish teaching hospital for the treatment of lower urinary tract symptoms related to benign prostatic hyperplasia.

Methods: A pilot study of men with moderate to severe lower urinary tract symptoms who underwent Rezum treatment to the prostate was performed.

Public attitudes towards learning disabilities (LDs) are generally reported as positive, inclusive and empathetic. However, these findings do not reflect the lived experiences of people with LDs. To shed light on this disparity, a team of co-researchers with LDs created the first online survey to challenge public understanding of LDs, asking questions in ways that are important to them and represent how they see themselves.

Background: Radiology interest groups (RIGs) can serve as a means of increasing exposure of the radiology specialty early in the medical curriculum while also increasing educational opportunities. However, the organizational structure and various functions of individual RIGs in Canada are not well-documented. We performed a survey of all active RIGs in Canada for the purpose of better understanding their structure, function, and opportunities for improvement.

Background: Sarcopenia is associated with increased morbidity and mortality in oncologic and transplant surgery. It has a high incidence in chronic inflammatory states including inflammatory bowel disease (IBD). The validity of existing data in IBD and of sarcopenia's correlation with surgical outcomes is limited.

We report an usual case of hepatic portal venous gas (HPVG) in the setting of acute pancreatitis and small bowel ischemia. Interestingly, the HPVG disappeared within 2 hours of the original computed tomography scan, despite the patient having small bowel ischemia. The patient had a complicated clinical course, dying 62 days postadmission.
