Model to predict malignancy among Bosniak III cysts

This retrospective study over a 15-year period is to identify independent predictors of malignancy in Bosniak III (BIII) renal lesions and to build a prediction model based on identifiable clinical variables. These cysts, characterised by contrast-enhanced computed tomography (CECT), have...

What should we do with the incidentally detected renal cyst in a child?

The introduction of routine prenatal screening in the early 1980s resulted in paediatric urologists being confronted with the dilemma of what to do with antenatally-detected urinary tract dilatation, many of whom, we now know, do not require long-term surveillance or...

I wasn’t expecting that! A series of unexpected radiology findings

Case 1 A 76-year-old diabetic man with a long-term catheter presents to the Emergency Department with rigors and non-specific abdominal pain. He has an elevated white cell count (WCC) and C-reactive protein (CRP). An abdominal and pelvic CT scan was...

Indeterminate renal lesions – a pragmatic imaging approach

The incidence of renal cell carcinoma (RCC) in the UK has increased steadily over the last two decades, largely driven by the increasing use of abdominal imaging and the incidental detection of small renal lesions [1]. The majority of incidental...

Urachal anomalies in children: surgical or conservative treatment?

Urachal anomalies are rare with an incidence of 1:5000-8000 live births. There is still some controversy as to whether to treat them expectantly or surgically with published reports describing malignant changes in adulthood. These authors describe their retrospective series of...

Near-infrared fluorescence in robotic surgery

This is a systematic review and critical analysis of the current evidence on the applications of near-infrared fluorescence (NIRF) in robotic urologic surgery. It uses indocyanine green (ICG), a sterile water-soluble dye which has been tested in various fields. In...

Imaging and Intervention in Urinary Tract Infections and Urosepsis

Urinary tract infections (UTIs) are highly prevalent in the community and account for approximately 40% of hospital-acquired infections. Yet, they are often underestimated and under-diagnosed: as one chapter of this book is entitled, nothing is simple about acute pyelonephritis. This...

LARP – three instrument techniques to reduce costs

The cost of laparoscopic radical prostatectomy (LARP) is high because of both the initial installation cost and, more importantly, high running costs. The main reason for the latter is the limited number of usage of the instruments; generally, each instrument...

A review of the diagnosis and management of urethral caruncles

Introduction The innocuous urethral caruncle is the most common benign urethral lesion in females. It can pose a significant challenge to urologists due to the plethora of differentials and poor evidence surrounding management. In 1926, Ferrier eloquently described the macroscopic...

Male infertility

Definitions Infertility is the inability of a sexually active, non-contracepting couple to achieve spontaneous pregnancy in one year [1]. About 15% of couples do not achieve pregnancy within one year and seek medical treatment for infertility. Semen parameters are standardised...

Characteristics of testicular tumours in prepubertal children

It is well known that testicular tumours in children occur in one of two peaks. Firstly, in the first four years of life where a third to half of these tumours are benign and secondly during puberty where there is...

Prostate abscess

Prostate abscess (PA) is a relatively uncommon clinical condition which is often difficult to diagnose because clinical symptoms are non-specific. It may be associated with a significant fatality rate, estimated to be between 3% and 30%, which may reflect its...
