Assessment of distal ureteral and ureterovesical junction visualization on contrast-enhanced voiding urosonography.

Pediatr Radiol 2021 Feb 12. Epub 2021 Feb 12.

Department of Medical Imaging, Ann & Robert Lurie Children's Hospital, 225 E. Chicago Ave., Chicago, IL, 60611, USA.

Background: Contrast-enhanced voiding urosonography (CEVUS) uses intravesically administered microbubble contrast to detect vesicoureteral reflux (VUR) and urethral anomalies with ultrasound. Multiple studies have suggested CEVUS can replace voiding cystourethrogram (VCUG) as a radiation-free alternative. Analysis of the ureterovesical junction and ureters on VCUG documenting the ureterovesical junction position, ureteral duplication, periureteral diverticula and ureteroceles is important as anatomical variations may affect management and surgical approach.

Congenital Anomalies of the Upper Urinary Tract: A Comprehensive Review.

Radiographics 2021 Mar-Apr;41(2):462-486. Epub 2021 Jan 29.

From the Department of Radiology, Diagnósticos da América SA (DASA), Av Juruá 434, Alphaville Industrial, Barueri, SP 06455-010, Brazil.

The upper urinary tract is the most common human system affected by congenital anomalies. Congenital anomalies of the kidneys and ureters comprise a wide spectrum of disorders ranging from simple variants with no clinical significance to complex anomalies that may lead to severe complications and end-stage renal disease. They may be classified as anomalies of renal form, which are subclassified as structural anomalies (eg, persistent fetal lobulation, hypertrophied column of Bertin, and dromedary hump) and fusion anomalies (eg, horseshoe kidney and pancake kidney); anomalies of renal position (eg, renal malrotation, simple renal ectopia, and crossed renal ectopia) and renal number (eg, renal agenesis and supernumerary kidney); and abnormalities in development of the urinary collecting system (eg, pyelocaliceal diverticulum, megacalycosis, ureteropelvic junction obstruction, duplex collecting system, megaureter, ectopic ureter, and ureterocele).

Diagnostic clues, pitfalls, and imaging characteristics of '-celes' that arise in abdominal and pelvic structures.

Abdom Radiol (NY) 2020 11;45(11):3638-3652

Department of Internal Medicine, Pratumthani Hospital, 7 Ladlumkaew Muang District, Pratumtani, 12000, Thailand.

'-Celes' is an ancient Greek language suffix that means 'tumor,' 'hernia,' 'swelling,' or 'cavity.' There are many '-celes' in the abdomen and pelvis that may be encountered during routine imaging interpretation, including santorinicele, choledochocele, ureterocele, lymphocele, mucocele, rectocele, cystocele, peritoneocele, varicocele, spermatocele, hydrocele, hematocele, pyocele and syringocele. Most '-celes' are detected incidentally at imaging for other clinical indications, but some deserve more attention due to a range of clinical symptoms or functional disorder that can adversely affect patient quality of life.
