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,...

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...

Can continence and volitional voiding be achieved in bladder exstrophy?

Bladder exstrophy is a challenge to the paediatric urologist; here in the UK, repairs are now undertaken at two centres in order to concentrate experience. The ultimate aim is to achieve urinary continence and volitional voiding. In this study, John...

Long-term risks of augmenting the bladder in spina bifida patients

Bladder augmentation is utilised to treat children with neuropathic bladders secondary to spina bifida that results in hostile urodynamics, renal deterioration and / or urinary incontinence. Whilst it is associated with an improved quality of life and low mortality, it...

Rare and Complex Urology

Diseases that are rare or of low prevalence pose challenges to provision of high-quality care because of limited available knowledge and sparse good-quality evidence regarding uncommon presentations, mechanisms of disease, and optimal treatments. Approximately 80% of rare diseases are of...

PFMT in males

Pelvic floor muscle training (PFMT) has been described since ancient times in Rome but Kegel popularised it to improve sexual and urinary health after childbirth. In the paediatric population, there is a paradigm shift towards biofeedback-based PFMT for lower urinary...

Assessing resolution of isolated hydronephrosis – is APPD superior to the SFU system?

Antenatal scanning detects urinary tract dilatation in 1-5% of pregnancies. Isolated hydronephrosis (i.e., that not due to secondary dilatation e.g. bladder dysfunction) is known to resolve or improve in most; some patients may, however, require intervention through deterioration of obstruction...

A tale of two cities – hypospadias outcomes

As urologists, it is important to know our results. In terms of hypospadias surgery, which is commonly undertaken after the age of one year in the UK, long-term follow-up is required to fully acquire this knowledge. Long-term urinary outcomes and...

Is robotic pyeloplasty in the under-ones as good as open repair?

Pelviureteric junction obstruction (PUJO) is a common cause of paediatric hydronephrosis. Indications for intervention include reduced renal function (<40%), symptoms (urinary tract infection or pain) and increasing dilatation. Although the Anderson-Hynes open pyeloplasty (OP) has long been the gold standard...

Robot-assisted ureterocalicostomy

Ureterocalicostomy was first introduced by Neuwirt (1947) and further described by Jameson et al. (1957) as an alternative procedure for repair of pelviureteric junction (PUJ) obstruction associated with an intrarenal pelvis. Performing ureterocalicostomy for PUJ repair has been suggested in...
