Controversy has...

A guide to percutaneous nephrolithotomy

Percutaneous nephrolithotomy (PCNL) is now the gold standard approach to treating large renal stones. Since its development in the 1970s, it has undergone a series of refinements that could only have been possible with the symbiosis of both radiological and...

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...

Radiological appearances of non-vascular renal anatomical variants

Anatomical variants of the renal tract are common and, although often asymptomatic, may present with complications. It is essential to identify anatomical variants, as this may have an impact upon surgical planning and management. This article aims to demonstrate radiological...

Increasing patient hydration through technology

Achieving optimal hydration is crucial particularly for patients with nephrolithiasis. Research suggests that intake should approach 2.5–3.5 litres per day to allow for the daily excretion of 2–3 litres of dilute urine [1]. Unfortunately, patient compliance is known to be...
