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,...

Pyonephrosis: is the kidney always doomed?

Pyonephrosis (Greek pyon ‘pus’ + nephros ‘kidney’) is defined in Campbell-Walsh Urology [1] as an infected hydro-nephrosis associated with suppurative destruction of the renal parenchyma which results in total or near total loss of renal function. The true incidence of...

UTI and VUR in children with mild antenatal hydronephrosis

This paper describes a retrospective analysis of 760 (608 males, 162 females) patients identified with mild antenatal hydronephrosis (defined by an anteroposterior (AP) pelvic diameter of 7-10mm in the third trimester and persistent postnatal dilation) looking at the incidence of...

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...

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...

Laparoscopic transposition of renal lower pole crossing vessels

The vascular hitch procedure for pelvi-ureteric junction obstruction (PUJO) was initially described by Hellstroem in1951 and has become popular again since the introduction of laparoscopy. There is still much controversy as to its efficiency. The authors of this paper analyse...

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)...

Urological Complications of Malignancy

Case 1 1. What does this sagittal magnetic resonance imaging (MRI) scan show? 2. Which cancers commonly cause this? 3. What is the acute management? Case 2 1. What is the diagnosis? 2. What local effects can this mass cause?...

Radiology quiz

We are delighted to introduce something new for the Uroradiology Focus – our very own Jane Belfield has put together a urology imaging quiz with 10 cases designed to grab your interest and test your knowledge. Good luck and let...

Bladder debris on ultrasound as a predictor for positive urine culture

One of the common ultrasound findings in children who undergo renal tract evaluation is ‘debris in the bladder’. The aetiology of bladder debris is varied and the likelihood that urinary debris represents positive urine culture is debatable. The authors of...

Emergency department revisits for patients with ureteral stones

The authors aimed to identify clinical predictors for emergency department (ED) revisits in patients diagnosed with ureteral stones. Patients presenting between 2010 and 2013 were included. Those who were admitted at the initial presentation were excluded. CT scans were reviewed...

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...
