Fetal bilateral renal pelvis without separation What does that mean?

The renal pelvis refers to the position where the ureter is connected to the kidneys. If there is no separation of the bilateral renal pelvis of the fetus, it means that the renal pelvis is normally developed and does not cause separation. It is recommended that pregnant women do not worry too much. This is the phenomenon of normal growth and development of the fetus, but if renal pelvis separation occurs, the general gap is about 10 mm, and there is also the possibility of recovery.
