“…In our study including 48 cases of VUR (94 kidneys), no correlation was found between CEC separation and the presence of VUR (including advanced VUR), as shown in Table 5. A variety of methods have been suggested for non‐invasive diagnosis of VUR using renal ultrasonography, but these procedures and their present diagnostic accuracy are not suitable for screening 23−26 . Needless to say, VCUG is the ‘gold standard’ for diagnosing VUR.…”

“…A variety of methods have been suggested for non-invasive diagnosis of VUR using renal ultrasonography, but these procedures and their present diagnostic accuracy are not suitable for screening. [23][24][25][26] Ultrasonographic Screening for Congenital Anomalies of the Kidney and Urinary Tract indicated that the screening cost per child would be ¥1200, and three potential dialysis patients would be found per 55 000 children. If dialysis in these 3 patients could be delayed for 3.7 years, screening would pay for itself.…”

“…Colour Doppler sonography (CDS) improved sonographic VUR diagnosis, particularly in patients with reflecting particles in the urine. Some authors report on CDS allowing VUR detection in patients with clear urine; however, this technique is timeconsuming, equipment/investigator dependent, and tends to work only in dilated ureters [87,88,89]. Finally, various bladder-filling techniques have been introduced for US cystography or reflux sonography (cystosonography, CS).…”

The aim of this study was to describe and discuss the various forms of cystography and their clinical value. Conventional fluoroscopic voiding cystourethrography (VCU), radionuclide cystography and the various sonographic cystographic approaches, including echo-enhanced cystosonography (EECS), are described. Their indications, potential, benefit and setbacks/restrictions are discussed with regard to the literature and the constantly changing clinical demand. With the introduction of EECS a new and reliable tool has been established to be useful for follow-up and screening for vesico-ureteral reflux (VUR); however, with the growing importance of functional disturbances a reliable method to evaluate both function and anatomy/VUR as offered by modified VCU is mandatory, and thus VCU remains to play a major part in evaluating children with urinary tract infection, suspected VUR, hydronephrosis or functional bladder disturbances. While EECS offers a new method for certain indications, such as follow-up examinations in VUR or screening, VCU remains an irreplaceable tool for evaluating anatomy (particularly the male urethra) and bladder function (if performed using the modified technique).

“…In experimental studies on miniswine, ultrasonographic cystograms using microspheres of albumin could demonstrate reflux (77), but the clinical usefulness of this technique has not been proven. Interesting but controversial (78) results have been reported using colour flow ultrasonography (79,80). Common to the various ultrasound techniques are difficulties in anatomical assessment of the bladder and urethra, in grading reflux, in operator dependency and in obtaining universally interpretable images.…”

Diagnosis of vesico‐ureteric reflux

The demonstration and grading of reflux is crucial in examination and follow‐up of any child with upper urinary tract infection. A variety of factors can influence the occurrence of reflux, e.g. race, genetics, state of maturation of the ureterovesical valve, diuresis, infection and bladder dysfunction, including obstruction and neurogenic disorders. Even when reflux is investigated under strictly standardized conditions, two consecutive bladder fillings frequently show different grades of reflux. Voiding cystourethrography is, to date, the only method with a generally accepted, well‐defined grading of reflux. It also allows detection of intrarenal reflux and anatomical and functional information about the bladder and urethra that is unobtainable by other methods. It is therefore usually considered the method of choice. Radionuclide cystography and, possibly, contrast enhanced ultrasonography can be complementary to voiding cystourethrography, but mainly for postoperative follow‐up and screening of siblings.
