MRU for diagnosis of paediatric ureteral stricture
Hydronephrosis is diagnosed antenatally in approximately 1-5% of all pregnancies. A rare cause is ureteral stricture, found in 4% of these cases. This study reports a series of 28 strictures diagnosed over a 10-year period by magnetic resonance urography (MRU)...
Refluxing ureteral reimplantation
Obstructed megaureters may be managed with temporising stents, cutaneous ureterostomies, or in older children with ureteral reimplantation (usually if the child is over one year of age). Cutaneous ureterostomies have risks of stomal stenosis, infection and leakage problems over nappies...
Antibiotics and flexible cystoscopy
This study is from Memorial Sloan-Kettering Hospital in New York, USA. Thousands of flexible cystoscopies are performed every day worldwide. Do they need antibiotic cover? Flexible cystoscopy may cause urinary tract infection (UTI) in less than 10% of cases. Asymptomatic...
Convective radiofrequency water vapour thermal therapy for BPH
There are a number of new treatments for benign prostatic hyperplasia (BPH) on the market. This paper reports retrospective data for 129 patients treated with convective radiofrequency water vapour thermal therapy (Rezum) by a single surgeon. There is variable length...
Urinary tract infections and antibiotics – the debate goes on
A large number of hospital patients and primary care patients suffer from recurrent urinary tract infection (UTI) and urosepsis. Some of these patients end up in intensive care units with multi-organ failure. New draft guidance from the National Institute for...Lasers in urology
1. What does LASER stand for? 2. What elements are involved and how is a LASER created? 3. The following cases involve laser surgery. Can you diagnose the pathology, identify which type of lasers can be used, and their wavelengths?...
CROWN initiative – what is it about?
The editors of around 50 journals related to women’s health have joined forces to support the CROWN initiative (core outcomes in women’s health). The aim is to standardise the collection of outcomes for all trials in a specific dataset in...In conversation with Matthew Bultitude
Matthew Bultitude. Can you tell us a little bit about what led you into the field of urology and what have been the highlights so far? Thank you and that is a very interesting question given that my father was...
The potential of statin use in castrate resistant prostate cancer treatment
One of the mechanisms by which prostate cancer achieves castrate resistance is through de novo intratumoral production of androgens. Reactivation of androgen receptors results in promotion of cell survival and proliferation pathways despite castrate serum testosterone levels. As androgen synthesis...
Comparison of PCNL under spinal versus general anaesthesia
There are several advantages of performing percutaneous nephrolithotomy (PCNL) under spinal anaesthesia including lower cost, reduced adverse effects and less tracheal tube displacement. Another advantage is that the patient remains awake throughout making positioning easier and reducing the risk of...
Is TRUS and biopsy obsolete as a diagnostic test for prostate cancer: refining the perineal biopsy technique?
Whilst there has been a dramatic shift in how patients are investigated for potential prostate cancer, transrectal ultrasound (TRUS) and biopsy remains the most commonly used technique for tissue sampling. In this single centre, retrospective analysis, 634 men, over a...
