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.
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered. Pluto was discovered by Clyde Tombaugh in 1930 and was originally considered to be the ninth planet from the Sun. After 1992, its planethood was questioned following the discovery of several objects of similar size in the Kuiper belt. In 2005, Eris, which is 27% more massive than Pluto, was discovered.
