Case 1 What radiological test is this and what does it show? What is the typical radio-nucleotide used for this study, what is its half-life and how is it excreted? Approximately how long does this study take to perform? What...

Changing concepts in endourological training – SIMULATE trial

Skill acquisition for endourological procedures is markedly different from traditional open surgical procedures, questioning the applicability of the presently used apprenticeship model. The lack of a universal simulation training curriculum has hampered its adoption into mainstream urological training. This study...

Focal therapy trials

Men with localised prostate cancer have traditionally required whole gland treatment involving radical prostatectomy or radical radiation treatment, independent of disease location and size. Increasing evidence supports the use of active treatment only in those men diagnosed with prostate cancer...

The impact of FGM on the genitourinary system: a 2021 perspective

Awareness of female genital mutilation (FGM) in European countries has increased over recent decades as a result of globalisation and migration of populations. The World Health Organization (WHO) describes FGM as procedures that involve partial or total removal of the...

Can PET/CT help in selecting treatment for patients with muscle-invasive bladder cancer more appropriately?

Radical cystectomy is one of the most drastic procedures that urological patients have to undergo with a five-year mortality of around 50% in those with organ-confined disease at presentation. Traditional imaging is with contrast-enhanced computed tomography (CT) but lymphadenectomy often...

Nocturia – the Cinderella of lower urinary tract symptoms

Nocturia is defined as waking during the night (at least once) to urinate. The important part of the definition relates to the necessity of sleep to precede the episode (although whether sleep must follow the episode is less clear). The...

Testing radical prostatectomy in men with prostate cancer and oligometastases to the bone: a randomised controlled feasibility study

Prostate cancer is the commonest cancer and the second most frequent cause of cancer death in Western men [1]. The recent STAMPEDE data suggests a median survival of just 42.1 months in the control arm of metastatic men [2]. Current...

The microbial syndicate: dysbiosis and origins of recurrent UTIs

Traditional dogma held that urine was sterile. However, recent molecular studies have revealed an underground microbial community, known as the urinary microbiome or ‘urobiome’ [1]. Far from being harmful, this community of microorganisms helps modulate immune responses, regulate inflammation, and...

Preoperative risk stratification of high-risk prostate cancer patients

High-risk prostate cancer (HRPCa) is associated with a significant risk of recurrence after radical treatment. While several classification systems exist, the D’Amico criteria – based on clinical T stage ≥T2c, prostate specific antigen (PSA) ≥20 ng/mL, or Gleason score (GS)...

Mechanisms and prevention of catheterisation associated urethral injury (CAUI)

Urethral catheterisation is a common procedure performed by health professionals across different grades and specialties in a variety of clinical settings. An estimated 15-25% of hospitalised patients have a urinary catheter inserted during their inpatient stay and up to 13%...

The emerging role of physician associates in urology

The physician associate (PA) is a new role in the NHS which has expanded across medical and surgical specialties to include urology. In the USA, it has long been an established field of practice where physician assistants work autonomously within...

The future of bladder preservation for muscle-invasive bladder cancer

Localised muscle-invasive bladder cancer (MIBC) has historically been treated with radical cystectomy (RC), but bladder preservation therapy (BPT) has emerged as a credible and increasingly refined alternative. Early work by Herr in the 1980s demonstrated that radical transurethral resection of...
