Hi Makeawish1314,
Yes, good to get another specialist scan else where to scan another time.
If you can, get another gynea opinion too. (Prof George Yeo Seow Heong from KKH - my gynea said that he is the expert in this area of antenatal diagnostic clinic)

Thankful to know that the left kidney of baby is working fine (my gynea told me he has seen some babies with tumour / other illness in the kidneys) - when the baby's born, some may need additional medical intervention, while some actually are rather healthy too.
Not being able to see on ultrasound scan may not mean that baby really does not have the right kidney - afterall,
it is a scan technique that has its set of limitations. (There are many cases where people mistook the genders for baby, down sydrome baby, having tumour in the baby's body, etc, but when the baby is born, he/she is perfectly normal & healthy)
A friend had her detailed scan in Novena Medical earlier - it showed that baby had some enlarged part in brain, but another scan in KKH shows that baby's perfectly normal & she is almost due now.
I saw on some websites that babies with one kidney can still sufficient kidney function to grow & develop normally while some may need to take some precautions.

Do ask your Gynea for more reading materials online ok & look on the bright side? (there are alot of web info that may not be necessary accurate as well, so sources from your gynea will be better)
For our case -
Though the scan looks like our baby's both kidneys has more white patches (indicating that they could be possibly polycystic? which if it does happen, baby may not be able to produce urine at all, and could possibly lead to baby not able to survive through pregnancy as amiotic fluid is partly made up of urine from baby as well).
But as baby's current bladder size &function, kidney function, structure & amiotic fluid volume is all normal, the doctors told us that baby is growing fine & we do not need to worry - we just need to monitor and check again after birth. (We do have to surrender our occasional worries by prayers to God for him daily)
p/s: Our baby no.2 was born with 2 small holes in the heart when he came - but after one year, God heals him as we continue to pray for him to be fully well. Even when he was still having those holes, doctor thinks that these will not affect him performing sports or doing olympics.
His reflux (often throw up after breast feeding, refuse to drink milk) was also gone after 4 months. It was tough initially!
Having a little life growing inside you is a miracle by itself - another amazing thing is that babies does not stay the way it is when the scan is taken as well. They grow & develop beyond what we can imagine or see.
Do take care there & stay on the positive side - as your emotions (stress/anxiety, etc) will very much affect the baby's growth & development...
Will be praying for you & your baby that he/she will be healthy and God's miracles will follow him/her!
Hope to hear good news in time to come! jiayou~!
