A new haemostatic agent in tubeless PCNL

Various agents have been...

Urolithiasis – metabolic considerations

Case 1 A 32-year-old female patient is diagnosed with a ureteric calculus for the first-time. What type of metabolic evaluation investigations should be performed? When should stone analysis be repeated? What are the most common metabolic abnormalities associated with calcium...

The role of continuous prophylactic antibiotics following JJ stent insertion

Urinary tract infections (UTI) and stent-related symptoms (SRS) are frequently recognised complications of ureteric stent placement. Antibiotic administration at induction prior to ureteric stent insertion is recommended by the European Association of Urology (EAU). Commencing prophylactic antibiotics for the ‘entire...

Why bother? Metabolic screening for stone formers

Introduction Despite the considerable increase in the incidence of stone disease in the UK and elsewhere in recent years, urologists have engaged with preventative strategies to only a limited degree. With mounting evidence of the strong correlation between obesity and...

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...

Pyonephrosis: is the kidney always doomed?

The management of renal calculi – Pt 2

Renal calculi can be managed according to four treatment options: conservative management, extracorporeal shock wave lithotripsy (ESWL), flexible ureterorenoscopy (FURS) and percutaneous nephrolithotomy (PCNL). Having addressed conservative management and ESWL in the last edition of Urology News, the second article...

Percutaneous ultrasound guided endoscopic lavage of perinephric abscess – different, but not necessarily better

Perinephric abscess is an uncommon but serious form of urosepsis. It develops as a consequence of the extension of an infection outside of the parenchyma of the kidney in acute pyelonephritis, or more rarely from haematogeneous spread of an infection...

Do stones still kill?

This paper is a retrospective analysis of deaths ascribed to stone disease in England and Wales over a 15-year period. The data was obtained from the Office of National Statistics, based on mortality derived from death certificates. One thousand, nine...

Stepwise voltage ramping causes less renal haematomas than fixed maximal voltage ESWL

Extracorporeal shock wave lithotripsy (ESWL) remains the recommended first line treatment for stones <2cm in the renal pelvis and upper or mid-pole calyces (Türk C, Knoll T, Petrik A, et al. European Association of Urology Guidelines on Urolithiasis. 2014). There...
