question: My grandaughter is 2 1/2 yrs old. In the hospital w/bronchitis and sinusitis. She just did a urine specimin after not voiding for approx. 8 or 9 hrs  in a large clear container. The urine had what appeared to be small bugs in it. Almost looked like fleas. What could this be?  Nurse, states, "probably some type of parasite coming from rectum", but that many? Looked like around 20 or so... No Stool, urine only, no c/o's itching, burning, etc, vomiting, 103 temp, and this just unexpectedly happened...
