What is a voiding cystourethrogram (VCUG)? A voiding cystourethrogram (VCUG) allows us to evaluate your child's urethra and bladder size, shape, and capacity. This procedure uses x-rays and a contrasting agent that is administered by catheter into your childâs bladder. A VCUG can also help us determine whether your child has reflux â a condition where urine from the bladder goes upward back to the kidneys.
Finally, after five years of searching, on August 30, 1992, Jewitt and Luu announced the Discovery of the candidate Kuiper belt object (15760) 1992 QB1. Six months later, they discovered a second object in the region, (181708) 1993 FW.
The Kuiper-Edgeworth Belt is named for the astronomers Gerard Kuiper, who theorized about a disk of material in the outer reaches of the solar system, and Kenneth Edgeworth, who had the idea that the outer solar system contained a number of small bodies, perhaps left over from the formation of the Sun and planets.he Kuiper Belt extends from roughly the orbit of Neptune (at 30 AU out to about 55 astronomical units from the Sun. The main body of this belt covers much of this region, ranging from nearly 40 AU to 48 AU.
