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.
Kuiper Belt comets tend to have short orbital periods â usually around 200 years â and are therefore also known as short period comets. Some comets are thought to come from the Oort Cloud, a region almost a light year from the Sun.hey are primarily made of dust and ice. Considered to be remnants of the formation of our Solar System, most comets belong to the Kuiper Belt, a region beyond the orbit of the planet Neptune. Comet PanSTARRS was visible in early 2013.
