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 discovered two natural satellites of planets in the Solar System, namely Uranus 's satellite Miranda and Neptune 's satellite Nereid. In addition, he discovered carbon dioxide in the atmosphere of Mars and the existence of a methane-laced atmosphere above Saturn 's satellite Titan in 1944. Kuiper also pioneered airborne infrared observing using a Convair 990 aircraft in the 1960s.
