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...

Modern management of small renal masses

With the advent of widespread cross-sectional imaging there has been a surge in incidental detection of small renal masses (SRMs) and renal cell carcinoma (RCC) is now the seventh most common cancer in the UK. Whilst surgical excision for larger...

What is new in lasers for endourology: looking into the future

From the first cystoscopic argon and neodymium-YAG (yttrium-aluminium-garnet) laser used for bladder tumours in 1976 by Staehler et al. [1], lasers have proven to be a versatile and an evolving tool in the therapeutic management of a variety of urological...

PUJO: Hellstrom principle revisited

This paper describes the result of four out of twenty-three cases (two males, two females) of pelvi-ureteric junction obstruction - PUJO - (mean age 18.25 years, range 16-20), mean follow-up two years (range six months – three years) that were...

The best stone man north of the border

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 1860, Sir Henry Thompson (1820–1904), the famous 19th century English surgeon and...

Is outpatient robotic surgery feasible in children?

Minimally invasive surgery has helped to achieve shorter hospitalisations, reduce postoperative pain and analgesia requirements and provides better cosmetic results. Robotic urological outpatient surgery has been examined in recent times in the adult population; here Neheman et al. look at...

Supranormal function on MAG-3 – what is its significance and how to predict?

Differential renal function (DRF) on MAG-3 scans is typically used in patients with pelvic ureteric junction obstruction (PUJ obstruction). Supranormal DRF is when the kidney with PUJO has higher DRF than the normal contralateral kidney. The authors in this study...

Sacral agenesis and neurogenic bladder: long-term outcomes of bladder and kidney function

These authors looked at single institution outcomes for sacral agenesis (without spina bifida) with reference to renal function and bladder function. All had urodynamics either at diagnosis (56%) or soon after. Of 43 patients (23 female, 20 male), 37 had...

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...

CRP to predict the need for surgical intervention in acute renal colic

A previous paper has suggested that C-reactive protein (CRP) is a useful serum marker for determining the likelihood of a patient with renal colic requiring surgical intervention, the cut-off level being >28mg/l (specificity 88.9%, sensitivity 75.8%). This prospective observational study...

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...

Urinary NGAL, KIM-1 and L-FABP concentrations in antenatal hydronephrosis

he elusive search for being able to diagnose pelvi-ureteric junction obstruction (PUJO) continues and this group of researchers investigated the possible clinical application of urinary neutrophil gelatinase-associated lipocalin (uNGAL), urinary kidney injury molecule-1 (uKIM-1) and urinary liver-type fatty acid-binding proteins...
