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...Missed Meyer-Weigert duplex ureter during emergency ureteric stenting for ureteric stones
The Meyer-Weigert rule is a fundamental anatomical principle in urology that describes the typical orientation of ureteral orifices in duplex kidneys. In a duplex system, the upper pole ureter usually inserts inferomedially, while the lower pole ureter inserts superolaterally. This...Urinary retention in women: what a general urologist should know
Urinary retention (UR) is classified by the International Continence Society (ICS) into acute (AUR) and chronic (CUR). AUR is defined as the “inability to pass any urine despite having a full bladder which is painfully distended and readily palpable or...Andrology (2016)
Case 1 Image A. Image B. Who is the mythological figure depicted in image A and how does he relate to a urological emergency? Define priapism and list five causes. In the context of a patient presenting with priapism, what...Prostatic fruit
In this series of articles, I am going to show you some of the exhibits contained in the Museum of Urology, hosted on the BAUS website (www.baus.org.uk). The topic for this month’s article was stimulated by two recent occurrences. The...
Predicting resolution of the primary obstructed megaureter
Primary obstructive mega ureter (POM) is the congenital dilatation of the ureter in the absence of other structural urinary tract anomalies and comprises 10–20% of prenatal hydronephrosis cases. It is often detected during workup for prenatal hydronephrosis and confirmed using...Seminal vesicle calculi
Epidemiology Seminal vesicle calculi are uncommon with just over 100 cases being reported in the literature, although the true incidence is likely to be higher [1-9]. Patients usually present aged between 30 and 45 years old and although the pathogenesis...Nocturia – the Cinderella of lower urinary tract symptoms
Nocturia is defined as waking during the night (at least once) to urinate. The important part of the definition relates to the necessity of sleep to precede the episode (although whether sleep must follow the episode is less clear). The...
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...
