My 8 month old baby has a multiseptated cystic lesion on/near her ovary.

Our beautiful baby girl was diagnosed at an ER in Florida (while we were on vacation) with a UTI.  They put her on an antibiotic and told us to check with our Dr. when we arrived home.  After 10 days on antibiotics they tested her urine again for continued infection.  They found that she still had a UTI and sent us for an ultrasound to check for obstructions and reflux.  On July 10, 2008 the ultrasound was performed and they noted ureter thickening (often related to reflux) and also found a 2.4 x 1.1cm "multilocular cystic lesion" at the base of her bladder, on/near her left ovary.  Her ovary was not seen.  Our pediatrician sent us to a pediatric urologist for further examination of the reflux and a second ultrasound to see the mass clearer.  She was put on a low dose antibiotic for the reflux and UTI.  At the urologist he suggested a VCUG to confirm the suspicion of vesicoureteral reflux.  After the VCUG and ultrasound (July 22) the urologist said that she definitely had stage II reflux and that most of these the children will grow out of it.  But in the mean time we must keep her on a low dose antibiotic to reduce the chance of infection of the bladder and to protect her kidneys.  He stated that the mass near her ovary was still there and that he would not comment on it because he was unsure what/where it is.  He referred us to a pediatric surgeon based on the radiologist's recommendations.  The radiologist now said that it measured 3 x 1.4cm and he called it "multiseptated cystic lesion".  They are still unsure of the etiology and location.  The pediatric surgeon requested a CT done before the appointment.  CT is scheduled for July 31 and surgeon appointment August 18.  Right now we are just supposed to wait and see.  How does one wait this long knowing that something seems to be growing inside their child and the professionals can not tell us what it is and what to do about it?
