Ipsilateral ureteroureterostomy: does function of the obstructed moiety matter?

Upper pole nephrectomy has been the traditional surgical management of children with poorly functioning upper pole moieties in duplex renal collecting systems having ureteral ectopia and ureterocele. However, ablative surgery confers a risk of functional loss to the remnant moiety...

ABU joins BCG in fight against NMIBC recurrence?

The authors test a hypothesis retrospectively in two cohorts of patients with non-muscle invasive bladder cancer (NMIBC), that endogenous bacteria in the bladder might exert antitumour effects, similar to live mycobacteria (BCG), through local immune-related or other mechanisms, on NMIBC...

Predictive factors for conservative treatment failure in paediatric blunt renal trauma

Blunt renal trauma is managed conservatively in children in the vast majority of cases. Grade IV renal injury is also generally managed non-operatively although occasionally intervention is needed for a urinoma that fails to settle. These authors retrospectively looked at...

Impact of MetS on prostate cancer (PCa)

Metabolic syndrome is associated with an increased risk of finding prostate cancer (PCa) overall and high-grade disease on biopsy. The first objective was to determine if MetS is associated with higher final PCa stage and grade on radical prostatectomy (RP)...

Bladder urothelial neoplasms in children

Urothelial bladder neoplasms are rare in children, occurring in 0.1-0.4% of the population before the age of 20. There are no current paediatric guidelines to their management. This study retrospectively reviews the files of patients from three tertiary centres between...

Performance status may alter outcomes in those treated with abiraterone

The drug therapies available for those with metastatic castrate-resistant prostate cancer have increased over the past few years. Abiraterone, a CYP17 inhibitor, has been proven effective in phase three trials, however those with poor performance status were largely under-represented in...

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...

Upper pole access is safe and effective for paediatric percutaneous nephrolithotomy

Upper pole access for percutaneous nephrolithotomy (PCNL) provides a straight access tract to the ureter with easier placement of a guidewire, good exposure of the pelvis and upper ureter, and comfortable manipulations for the treatment of staghorn, large upper caliceal,...

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...

Comparative effectiveness of nephron sparing surgery vs ablation

Nephron sparing surgery (NSS) and minimally invasive modality of thermal ablation have attracted great attention as an alternative surgical treatment to radical nephrectomy (RN) for renal tumours <4cm. High quality evidence comparing disease specific survival (DSS) is lacking. This issue...

Does stable or decreasing hydronephrosis on ultrasound lead to stable or improved function on diuretic renography?

Antenatal hydronephrosis is noted in approximately 1% of all pregnancies. Persistent renal obstruction may lead to progressive loss of renal function. Renal ultrasound (USS) is the preferred modality for diagnosis and monitoring of paediatric hydronephrosis as it is non-invasive, non-ionising,...

Lower pole vessels in children with PUJO: laparoscopic vascular hitch or dismembered pyeloplasty?

A crossing vessel accompanying pelvi-ureteric junction obstruction (PUJO) occurs in 25-50% of cases. The Hellstrom vascular hitch procedure was first described in 1951 and has regained popularity since 2003 in the era of laparoscopic surgery as it negates the need...
