Management of Small Testicular Masses: A Delphi Consensus Study.

Background And Objective: The majority of small testicular masses (STMs) are benign and therefore radical orchidectomy (RO) may represent overtreatment. In appropriately selected patients, surveillance or testis-sparing surgery (TSS) is an alternative option to preserve testicular function. Since there are no clear guidelines, we aimed to develop consensus recommendations on the management of STMs.

Imaging findings in suspected penile fracture: alternative diagnoses and surgical correlation.

Objectives: The primary objective is to compare the imaging and surgical findings in a cohort of patients with suspected penile fracture (PF).

Methods: Retrospective cohort study of all patients with suspected PF over an 11-year period at a tertiary referral andrology centre. All dedicated presurgical imaging with ultrasound (US) and MRI was analysed and correlated with intraoperative findings; alternative diagnoses were recorded.

Review of the role of imaging in the diagnosis of priapism.

Imaging has a specific role in the diagnosis and management of priapism. The primary imaging modality is ultrasound with colour Doppler (CDUS) which can accurately assess the hemodynamics of the cavernosal arteries. This is particularly useful in equivocal cases and can help differentiate ischemic from non-ischemic priapism as well as confirm the presence and location of arterio-venous fistulae post penile trauma.

Severe emphysematous pyelonephritis as a complication of klebsiella pneumonia and uncontrolled diabetes mellitus.

A female in her 40s, with poorly controlled Type I diabetes mellitus, was brought to our tertiary hospital by ambulance after being found drowsy. Six days prior, she had self-discharged from the Intensive Care Unit whilst being treated for a Klebsiella pneumonia. At re-admission, she had an acute kidney injury with abdominal pain and clinical features of sepsis.

Therapeutic outcomes and analysis of Doppler findings in 25 patients with non-ischemic priapism.

Non-ischemic priapism (NiP) is painless partial tumescence caused by genital trauma and the formation of intracorporal arterio-venous fistula. This is a retrospective study of 25 men with NiP and reports the long-term erectile function and colour doppler ultrasound (CDUS) findings after treatment for NiP. Unstimulated CDUS was performed at diagnosis, 1 week and at last follow-up after treatment.

Thrombus Distribution in Vaccine-induced Immune Thrombotic Thrombocytopenia after ChAdOx1 nCov-19 Vaccination.

Vaccination strategies have been at the forefront of controlling the COVID-19 pandemic. An association between vaccine-induced immune thrombotic thrombocytopenia (VITT) and one of these vaccines, the ChAdOx1 nCov-19 vaccine, is now recognized. The purpose of this study was to investigate the frequency and location of thrombosis in each vascular system using CT, MRI, and US to identify additional sites of thrombus in a United Kingdom-wide sample of patients with confirmed VITT.

Transcriptomic Profiling of Tumor-Stromal Cell Paracrine Crosstalk Identifies Involvement of the Integrin Signaling Pathway in the Pathogenesis of Mesenteric Fibrosis in Human Small Intestinal Neuroendocrine Neoplasms.

Aim: Analysis of the pathophysiology of mesenteric fibrosis (MF) in small intestinal neuroendocrine tumors (SI-NETs) in an paracrine model and in human SI-NET tissue samples.

Methods: An indirect co-culture model of SI-NET cells KRJ-I and P-STS with stromal cells HEK293 was designed to evaluate the paracrine effects on cell metabolic activity, gene expression by RT2 PCR Profilers to analyse cancer and fibrosis related genes, and RNA sequencing. The integrin signaling pathway, a specific Ingenuity enriched pathway, was further explored in a cohort of human SI-NET tissues by performing protein analysis and immunohistochemistry.

MRI in the Management of Prostate Cancer.

Multiparametric MRI has a changing role in prostate cancer diagnosis. Internationally recognized consensus documents such as prostate imaging reporting and data system version have been developed and adapted to standardize the acquisition and reporting of prostate MRI. The improvement in scanning techniques and development of highly sensitive functional sequences have improved the detection of clinically significant prostate cancer as well as treatment planning and follow up.

Percutaneous Renal Ablation.

Incidental small renal cell cancers are increasingly being diagnosed on cross-sectional imaging. This review article describes the indications for percutaneous ablation of small renal cell cancers, choice of ablation technologies and imaging follow-up.

Renal Cell Carcinoma: The Evolving Role of Imaging in the 21st Century.

Kidney lesions are commonly an incidental finding on cross sectional studies carried out for a variety of reasons. The detection of renal cell carcinoma (RCC) has increased accordingly. There are a variety of different contrast-enhanced CT imaging protocols that have been developed to help diagnose and stage RCC.

Viabahn stent graft in the management of a grade 3 coronary perforation.

Background: Coronary artery perforation during coronary intervention has high morbidity and mortality. This case describes the collaboration between interventional cardiologists and Interventional radiologists to successfully deploy a peripheral arterial stent graft in a coronary artery that demonstrated persistent extravasation after coronary specific stent graft placement.

Case Presentation: An 84 year old female patient presented with acute coronary syndrome and coronary angiography identified a right coronary artery lesion.

Clinicopathological correlations of mesenteric fibrosis and evaluation of a novel biomarker for fibrosis detection in small bowel neuroendocrine neoplasms.

Purpose: Mesenteric fibrosis (MF) in small intestinal neuroendocrine neoplasms (SINENs) is often associated with significant morbidity and mortality. The detection of MF is usually based on radiological criteria, but no previous studies have attempted a prospective, multidimensional assessment of mesenteric desmoplasia to determine the accuracy of radiological measurements. There is also a lack of non-invasive biomarkers for the detection of image-negative MF.

Predictors of antiproliferative effect of lanreotide autogel in advanced gastroenteropancreatic neuroendocrine neoplasms.

Purpose: The antiproliferative properties of lanreotide autogel (LAN) in gastroenteropancreatic neuroendocrine neoplasms (GEP NENs) were demonstrated in the CLARINET study. However, there is limited literature regarding factors that affect progression-free survival (PFS) in patients with GEP NENs treated with LAN.

Methods: We identified a total of 191 treatment-naive patients with advanced GEP NENs and positive SSTR uptake on imaging (Octreoscan or Gallium DOTATATE Positron Emission Tomography [GaPET]) who received first-line LAN monotherapy, albeit at various starting doses (60, 90 or 120 mg/month).

Transarterial Chemoembolisation of Colorectal Liver Metastases with Irinotecan-Loaded Beads: A Bi-institutional Analysis of 125 Treatments in 53 Patients.

Purpose: To retrospectively review outcomes in patients treated for colorectal liver metastases with DEBIRI.

Materials And Methods: A retrospective analysis of patients with CRLM treated with DEBIRI was performed between 2008 and 2017 between two tertiary centres. Outcome parameters were overall survival and hepatic progression-free survival, as well as safety.

Abnormal deep dorsal vein resulting in veno-occlusive erectile dysfunction.

A 59-year-old man with a 6-year history of erectile dysfunction presented to the andrology outpatient clinic. Multimodality assessment with ultrasound, MRI venography and fluoroscopic venography demonstrated an aberrant emissary vein arising from the corporal bodies causing venogenic erectile dysfunction. Selective coil embolisation of the collateral vein resulted in an almost immediate and sustained improvement in his erections.

Microbubble-enhanced ultrasound to demonstrate urethral transection in a case of penile fracture.

A 47-year-old man attended the emergency department following trauma during sexual intercourse after which he developed penile swelling and haematuria several hours later. A penile fracture was suspected but given the slightly atypical history, ultrasound was performed to look for a fracture. Given the history of haematuria, both a standard Doppler ultrasound and a microbubble-enhanced retrograde ultrasound urethrogram were performed.

Utility of MR enterography and ultrasound for the investigation of small bowel Crohn's disease.

Unlabelled: Cross sectional Imaging plays an increasingly important role the diagnosis and management of Crohn's disease. Particular emphasis is placed on MRI and Ultrasound as they do not impart ionising radiation. Both modalities have reported high sensitivity for disease detection, activity assessment and evaluation of extra-luminal complications, and have positive effects on clinical decision making.
