How does fetal bilateral renal pelvis dilation occur?
Disease description:
The older sister living next door gave birth to a baby this year, but the child was sent to the intensive care unit right after birth. I heard it's because the fetus had kidney problems, possibly caused by the mother's improper diet during pregnancy. The baby's entire body is swollen. May I ask what is the cause of fetal bilateral hydronephrosis?

Fetal bilateral renal pelvis dilation has complex and varied causes, potentially related to multiple congenital developmental abnormalities, urinary tract obstruction, genetic disorders, and other factors.
1. Congenital factors: Such as congenital ureteral stricture, horseshoe kidney, or duplicated kidney malformations. These developmental abnormalities may obstruct urine outflow, leading to hydronephrosis.
2. Urinary tract obstruction: Obstruction at any site along the urinary tract can cause kidney dilation, such as ureteral obstruction.
3. Vesicoureteral reflux: Backflow of urine from the bladder into the ureters may also lead to hydronephrosis.
4. Multicystic dysplastic kidney: This is a genetic disorder that may also result in bilateral renal pelvis dilation.
5. Other factors: Chromosomal abnormalities, cystic kidney disease, and others may also be associated with bilateral renal pelvis dilation.
