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.
We know of a number of planets outside our own solar system. The first one was discovered in 1995, and their numbers are approaching three hundred. Distances vary, and one (OGLE-2005-BLG-390Lb) is reported at 21,500 light years away.As you can imagine, they're very hard to see.In our solar system, we know of only the two dwarf planets beyond Neptune: Pluto and Eris. There may be more, but we don't know. The Kuiper belt begins at about the orbit of Neptune, and there is a lot of material in it to construct a planet.s you can imagine, they're very hard to see.
