Whether the separation of the renal pelvis has any effect on the fetus needs to be judged according to the cause. If it is physiological separation of the renal pelvis, it has no effect on the fetus, and regular checkups will be enough; if it is pathologic separation of the renal pelvis, it will have some effect on the fetus, and it needs to be treated under the guidance of a professional doctor in a timely manner.
If the separation of the renal pelvis is physiological, it is generally normal and will not affect the fetus, so there is no need to be overly nervous, but it may be due to the presence of urine in the bladder of the fetus during the examination process, so such symptoms will appear, and regular checkups will be sufficient.
If it is caused by pathological factors, it will have a certain effect on the fetus. Functional obstruction and other clinical diseases may lead to fetal hydronephrosis, which may directly affect fetal development, and in severe cases, may also lead to fetal developmental malformations, which need to be examined in a timely manner and treated under the guidance of a doctor.
Regular checkups are needed to understand the development of the fetus.
