baby's bladder is enlarged at 12 wks, CVS test

I'm 12 weeks pregnant & had an ultrasound today they told me my baby's bladder is enlarged. It is suppose to be 7mm & it's at 15.3mm. I'm having a CVS test done later this week to check for any Chromosome abnormalities. Dr. did explain what the worse case scenario could be, but told me we would wait for the test results go from there. Anyone who has gone through this can you please share your experience (good or bad) I got the impression it's not going to have a good prognosis.

Thanks for your question.
Ultrasound routinely identifies the increase in the dimensions of the fetal bladder from 10 weeks of gestation. The causes of enlarged bladder can be of two types: obstructive and non-obstructive. Obstructive causes may arise from obstruction of the flow of urine out of the bladder, it includes a spectrum of abnormalities and it depends on the sex of the fetus.
Among the obstructive causes it is most commonly in male fetuses the maldevelopment of the urethra, while in female bladder obstruction is usually the result of more complex defects in the development of the urogenital system often grouped under the term “cloacal plate abnormalities”.
Non-obstructive bladder problems are probably amongst the rarest of conditions, which form a heterogeneous group of sometimes complex abnormalities.
I hope I was able to address your query. If you have any further problems, please do not hesitate to go to the doctor.
Wishing you all the best.
