Tyrosine and tryptophan in urine as biomarkers for prostate cancer: A validation study.

Prostate cancer (PCa) is a common male malignancy and early diagnosis is crucial for successful treatment. The current study aims to validate results from a pilot study that demonstrated an inverse association between urine tyrosine and tryptophan levels and the severity of PCa. This study comprised a cohort of 97 patients with benign prostatic hyperplasia, 93 patients diagnosed with localized PCa, 75 patients diagnosed with locally advanced PCa, and 68 patients diagnosed with metastatic PCa.

The relationship between the force applied and perceived by the surgeon during ureteral access sheath placement: ex-vivo experimental model.

Purpose: To define a peak force of insertion (PFOI) threshold for ureteral damage during ureteral access sheath (UAS) placement on an experimental ureteral orifice model.

Methods: A specially designed water tank using 2 laparoscopic 5 mm ports and 2 different size (10 Fr and 8 Fr) sealing cap adaptors (SCA) as ureteral orifices was used to perform the test. A 10-12 Fr UAS was fixed to a load cell and the force of insertion (FOI) was continuously recorded with a digital force gauge.

Consultation on UTUC II Stockholm 2022: diagnostics, prognostication, and follow-up-where are we today?

Purpose: To summarise the current knowledge regarding diagnostics, prognostication and follow-up in upper tract urothelial carcinoma (UTUC).

Methods: A scoping review combined with expert opinion was applied to provide an overview of the current research field. Based on the published literature and the experts' own experience and opinions, consensus was reached through presentations and discussions at the meeting Consultation on UTUC II in Stockholm 2022.

Identification of early stage and metastatic prostate cancer using electrochemical detection of beta-2-microglobulin in urine samples from patients.

To improve prostate cancer (PCa) diagnosis, it is imperative to identify novel biomarkers and establish effective screening techniques. Here, we introduce electrochemical biosensing of β-2-Microglobulin (β2M) in urine as a potential diagnostic tool for PCa. The immunosensor is composed of a screen-printed graphene electrode coated with anti β2M antibodies.

Kidney stone disease is rapidly increasing with a strong relationship to metabolic syndrome. This review gives a brief overview of the current state and current treatment modalities. Increasing use of CT and ultrasound scans leads to increased diagnosis of asymptomatic kidney stones, which rarely require treatment.

Gadolinium-enhanced MRI visualizing backflow at increasing intra-renal pressure in a porcine model.

Introduction: Intrarenal backflow (IRB) is known to occur at increased intrarenal pressure (IRP). Irrigation during ureteroscopy increases IRP. Complications such as sepsis is more frequent after prolonged high-pressure ureteroscopy.

Healthcare Professionals' Experiences and Perspectives of Facilitating Self-Management Support for Patients with Low-Risk Localized Prostate Cancer via mHealth and Health Coaching.

Self-monitoring of self-management interventions with the use of mobile health (mHealth) can enhance patients' well-being. Research indicates that mHealth and health coaching act symbiotically to providing a more constructive outcome. Nurse coaches seem to have a significant role in translating the patients' tracked data.

Ehlers-Danlos syndrome (EDS) is a group of hereditary connective tissue disorders which are clinically characterized by hypermobility of joints, hyperelasticity of skin and tissue insufficiency, sometimes leading to herniation, bleeding, and organ rupture. This is a case report of a 55-year-old man with EDS and a big bladder diverticulum in which we discuss treatment strategy in patients with EDS and bladder diverticula. Initially, treatment approach should be conservative due to high recurrence rates and potential complications following surgical procedures.

An Intervention Offering Self-management Support Through mHealth and Health Coaching to Patients With Prostate Cancer: Interpretive Description of Patients' Experiences and Perspectives.

Background: Observational management strategies such as active surveillance and watchful waiting are considered to be acceptable approaches in patients with low-risk localized prostate cancer and a safe alternative to aggressive treatment. During observational management, treatment is postponed until the disease progresses, which often never occurs. However, approximately 90% of patients with a low-risk disease choose aggressive treatment owing to anxiety.

International Alliance of Urolithiasis guideline on retrograde intrarenal surgery.

Objectives: To set out the second in a series of guidelines on the treatment of urolithiasis by the International Alliance of Urolithiasis that concerns retrograde intrarenal surgery (RIRS), with the aim of providing a clinical framework for urologists performing RIRS.

Materials And Methods: After a comprehensive search of RIRS-related literature published between 1 January 1964 and 1 October 2021 from the PubMed database, systematic review and assessment were performed to inform a series of recommendations, which were graded using modified GRADE methodology. Additionally, quality of evidence was classified using a modification of the Oxford Centre for Evidence-Based Medicine Levels of Evidence system.

The Danish linguistic validation of the Ureteral Stent Symptoms Questionnaire.

Introduction: The aim of the study was to validate the Ureteral Stent Symptom Questionnaire (USSQ) in Danish for patients with indwelling ureteral stents.

Methods: The linguistic validation of the original USSQ was performed following standardised multi-step translation procedures. Seventy patients with indwelling ureteral stents were asked to complete the Danish USSQ one and two weeks after stent placement and four weeks after stent removal.

Correlation between stage of prostate cancer and tyrosine and tryptophan in urine samples measured electrochemically.

Prostate cancer (PCa) is the second most common cancer in men and one of the leading causes of cancer-related deaths. Early detection is the key to successful treatment and provides the greatest chance to cure the patient. Currently, early detection involves screening for prostate-specific antigen levels in blood, which is not a tumor-specific biomarker.

European Association of Urology Section of Urolithiasis and International Alliance of Urolithiasis Joint Consensus on Retrograde Intrarenal Surgery for the Management of Renal Stones.

Background: Retrograde intrarenal surgery (RIRS) has become the preferred treatment modality for nephrolithiasis. However, because of ongoing uncertainties regarding the optimal perioperative management, operative technique, and postoperative follow-up, as well as a lack of standardization for outcome reporting, consensus is needed to achieve more uniform clinical practice worldwide.

Objective: To develop recommendations for RIRS on the basis of existing data and expert consensus.

Renal stone detection using a low kilo-voltage paediatric CT protocol - a porcine phantom study.

Introduction: Reducing tube voltage is an effective dose saving method in computed tomography (CT) assuming tube current is not concurrently increased. Recent innovations in scanner technology now enable CT tube voltage reduction to 70 kV thereby increasing opportunities for dose reduction in paediatric patients, but it is unclear if the increased image noise associated with 70 kV impacts on ability to visualise renal stones accurately. The purpose was to assess detectability of nephrolithiasis using a bespoke paediatric phantom and low kV, non-contrast CT and to assess inter-observer agreement.
