Assessment and management of percutaneous nephrostomies

Nephrostomies are a valuable uroradiological intervention which enables drainage of the obstructed kidney, amongst other indications. Complications associated with nephrostomies following placement are not uncommon, with re-presentation to the emergency department or surgical emergency unit. In this review we will...

Dietary citrate substitution in urolithiasis patients

Stone formation is dependent on supersaturation of urinary salts and urinary crystal retention. Urinary promoters (protein aggregates, cell debris) and inhibitors (citrate, magnesium, urinary macromolecules such as glycosaminoglycans and proteins) are involved in the process of stone formation [1]. Hypocitraturia...

Occupational tumours of the urinary tract: The work of Denis Poole-Wilson

In this series of articles I am going to show you some of the exhibits contained in the Museum of Urology, hosted on the BAUS website (www.baus.org.uk). In the last article I said I would be taking you to the...

Demanding cases or nightmares in endourology? Sep/Oct 2015

One of the most interesting aspects of attending international meetings is the rare but invaluable, honest presentation of complex cases. We aim to present the readers with some complex and challenging ongoing cases in endourology. Case 1 A general practitioner...

Urinary retention in women: what a general urologist should know

All you need to know about percutaneous nephrolithotomy: supine versus prone and mini versus traditional

Introduction Since the first percutaneous nephrolithotomy (PCNL), the technique has undergone many innovations, including modifications in positioning, miniaturisation of instruments and combination with retrograde intra-renal surgery (see Table 1 for an outline of the history of the technique). Controversy has...

Hypercalciuria in children with monosymptomatic nocturnal enuresis

A new haemostatic agent in tubeless PCNL

Tubeless percutaneous nephrolithotomy (PCNL) is increasingly being used in carefully selected patients to reduce hospital stay and analgesia requirements, especially in those with little bleeding who become stone free or have insignificant residual fragments (usually <4mm). Various agents have been...

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...

Nocturia – the Cinderella of lower urinary tract symptoms
