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 (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...
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...
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...
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...
Background Pelviureteric junction obstruction (PUJO) is defined as a functionally significant impairment of urine flow from the renal pelvis into the proximal ureter. For more than a century, surgery was considered the first-choice approach to management. However, the widespread use...
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...
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)...
Case 1 A 28-year-old female, 19 weeks pregnant, presents with severe left loin pain. There is no past medical history of note. Blood tests show a white cell count of 14.1x109/L and creatinine of 56umol/L. An ultrasound scan (USS) reports...
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...
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...
