“…Lower moiety complications are VUR, renal scarring and PUJ obstruction. Our data are consistant with current literature where upper moiety complication is significantly more common than lower moiety complication, with upper moiety obstruction associated with a ureterocele being the most prevalent complication . VUR and renal scarring are the most common complications found in lower moiety duplex kidneys .…”

“…Duplex kidneys are a common abnormality of renal tract development, carrying an incidence of approximately 1%. [1][2][3] This diagnosis is defined as a renal unit comprised of two pelvicalyceal systems and is the most frequent congenital anomaly of the urinary tract. [4][5][6] There is much variation within the condition, therefore it is often further classified as either complete or partial.…”

“…Recognising these patients early is important as severe complications are symptomatic and can be treated effectively by early intervention. 2,13,14 Some of the most frequent complications are associated with ectopic insertion of the upper moiety ureter of a complete duplex, often occurring with an ureterocele, 8 (Fig. 2).…”

Introduction: Duplex kidneys are common, mostly asymptomatic and of no clinical significance. However, they can be associated with significant pathology, often with long-term morbidity. There is minimal literature on the review of the duplex kidney, its associated anomalies and complications. The purpose of this paper is to review our experience of imaging the spectrum of abnormalities associated with duplex kidneys in the paediatric population and correlate this with contemporary literature. Method: A retrospective review of the radiology database in a tertiary paediatric centre was performed. A word search of the Radiology Information System for 'duplex' of patients under the age of 16 was undertaken and limited to studies performed between 2006 and 2013. Results: Two hundred seventy-four patients were identified (age range 0-16, median 3 years, gender 59.9% female) who had 836 studies: ultrasound 598/836 (71.6%), nuclear medicine 180/836 (21.5%), micturating cystourethrogram 52/836 (6.2%), MRI 5/836 (<1%) and CT scan 1/836 (<1%). Patients were categorised as duplex and no complication (151/ 274 = 55.1%), upper moiety obstruction, lower moiety reflux/scarring, multicystic dysplastic kidney, abnormal ureteric insertion and other pathology. Conclusion: Duplex kidneys are common and often not clinically significant. However, this study demonstrates almost 50% of paediatric patients investigated for duplex kidneys had complications requiring treatment. The most common complications were upper moiety obstruction associated with a ureterocele and lower moiety vesicoureteric reflux. Ultrasound was the most common modality for early detection of these complications.
