I met with my OB today, and got some more clarification about what's going on with our little one's kidneys.
The official diagnosis for what she has is called fetal pyelectasis (click link for more info). A quick definition...
Enlargement of the part of the kidney that collects urine (the renal pelvis) from 4 to 10 millimeters in diameter is called fetal pyelectasis or “renal pelvic dilatation”. Dilation of the renal pelvis to greater than 10 mm is called severe pyelectasis or hydronephrosis.
So, anything in the 4-10 mm range is of concern, and once the kidney size hits 10 mm, it's considered severe. Both of our little girl's kidneys are at 9.8 mm. So, they are still out of the "severe" range, but just barely......a bit too close for my liking. Please pray that they do not get any larger.
It sounds like, in most cases, this issue resolves itself, oftentimes before birth even. She will continue to be monitored via ultrasound until she's born, and then will likely have an ultrasound on her just days after her birth. All of my doctors, as well as the ultrasound tech, have assured me that there's "nothing to worry about"....I wish it were that easy.
Prayers are cherished! And, in case you have forgotten what she looks like....=)
