Upper pole pathologies in duplex kidneys: an analysis of predictive factors for surgery and urinary tract infections from the Mid-Atlantic Pediatric Academic Consortium.

J Pediatr Urol 2022 May 29. Epub 2022 May 29.

Department of Urology, University of Virginia, Charlottesville, VA, USA. Electronic address:

Background/objective: While there is significant data on the natural history and outcomes for prenatal hydronephrosis in simplex kidneys, duplex kidneys tend to be less studied. Management can be quite variable based on provider preference. We aimed to describe practice patterns from several tertiary academic institutions, identify clinical predictors for surgical intervention and urinary tract infection (UTI) for upper pole pathology, and demonstrate the natural history of lower pole vesicoureteral reflux (VUR).

Concurrent Multicystic Dysplastic Kidney, Posterior Urethral Valves, and Obstructive Ureterocele in a Male Pediatric Patient: A Case Report.

Urology 2022 Apr 30. Epub 2022 Apr 30.

Division of Pediatric Urology, Department of Surgery, IWK Health Centre, Halifax, Nova Scotia, Canada; Department of Urology, Dalhousie University, Halifax, Nova Scotia, Canada. Electronic address:

Congenital anomalies of the kidney and urinary tract (CAKUT) are diagnosed in approximately 3-6 per 1000 live births and represent a spectrum of urologic conditions impacting the kidneys, ureter, bladder, and urethra. Although both are considered under the classification of CAKUT, there is no known unifying pathophysiologic mechanism for ureteroceles and posterior urethral valves with only 1 case report noted in the literature. Herein we report the only documented case of a patient with CAKUT related to posterior urethral valves, ureterocele, and multicystic dysplastic kidney. Read More

Sonographic differential diagnosis of duplex kidneys.

Karl-Heinz Deeg

Ultraschall Med 2022 Apr 29. Epub 2022 Apr 29.

Pediatric Clinic, University of Erlangen/Nuremberg, Erlangen, Germany.

Duplex kidneys have two renal pelvises and two ureters, which can join on the way to the urinary bladder but can also enter the bladder separately. A distinction must be made between normal and pathological duplex kidneys. In normal duplex kidneys, both renal pelvises are normal in width, and the upper and lower poles are approximately the same size. Read More

Giant hydronephrosis secondary to an ectopic ureter associated with bilateral duplex collecting system: a case report.

Oxf Med Case Reports 2022 Apr 19;2022(4):omac034. Epub 2022 Apr 19.

Division of Urology, Department of Surgery, Tishreen University Hospital, Latakia, Syria.

Giant hydronephrosis is an ultimate rare urologic entity; even rarer when it is secondary to a duplex collecting system. Duplex collecting system is a common urologic anomaly with a wide range of clinical symptoms and a variety of associated urologic abnormalities such as an ectopic ureter, ureterocele, vesicoureteral reflux and ureteropelvic junction obstruction. This report presents a case of an 8-year-old boy who had a bilateral duplex collecting system that was revealed accidentally by a bilateral severe hydronephrosis. Read More

Concomitant occurrence of pyelocalyceal diverticulum and ipsilateral large sized orthotopic ureterocele in an adult: a rare association.

Ravikanth Reddy

CEN Case Rep 2022 Apr 13. Epub 2022 Apr 13.

Department of Radiology, St. John's Hospital, Bengaluru, 560034, India.

Pyelocalyceal diverticulum is an incidental finding detected on routine ultrasonography scans which may also show symptoms of recurrent urinary tract infections secondary to urinary stasis and calculi formation within the diverticulum. Orthotopic type of ureterocele occurs as an isolated abnormality and is mostly confined to adults as opposed to ectopic type of ureterocele which is congenital in origin and commonly seen in children and is almost always associated with a duplicated collecting system. We report a case of concomitant occurrence of pyelocalyceal diverticulum and ipsilateral large sized orthotopic ureterocele diagnosed on high-resolution ultrasonography and confirmed on contrast enhanced computed tomography in a 54-year-old adult female.

Ureterocele as a cause of chronic intractable abdominal pain.

BMJ Case Rep 2021 Nov 11;14(11). Epub 2021 Nov 11.

Pain Management, Cleveland Clinic Foundation, Cleveland, Ohio, USA.

A ureterocele is a submucosal, cystic dilation of the terminal ureter, either congenital or acquired, as it enters the bladder. It is a rare clinical entity that can be entirely asymptomatic and present as an incidental finding or can manifest in the form of distressing symptoms such as unremitting abdominal pain, haematuria, obstructive uropathy, to name a few. The authors present a case of abdominal pain in a 43-year-old woman who was presumptively attributed to various clinical entities and was finally referred to the chronic pain clinic. Read More

Risk of urinary tract infection in patients with hydroureter: An analysis from the Society of Fetal Urology Prenatal Hydronephrosis Registry.

J Pediatr Urol 2021 Dec 21;17(6):775-781. Epub 2021 Sep 21.

CHOC Children's, Division of Pediatric Urology, Orange, CA, USA; University of California, Irvine, Department of Urology, Irvine, CA, USA.

Background: Prenatal hydronephrosis is one of the most common anomalies detected on prenatal ultrasonography. Patients with prenatal hydronephrosis and ureteral dilation are at increased risk of urinary tract infection (UTI) and continuous antibiotic prophylaxis (CAP) is recommended. However, current guidelines do not define the minimum ureteral diameter that would be considered a dilated ureter in these patients. Read More
