Is separation of both renal pelvises hereditary?

Bilateral renal pelvic separation can be said to be the place where the kidney and ureter are connected. The expansion of this place can cause kidney stones or ureteral deformities, and even cause abnormal urine excretion. Therefore, when the bilateral renal pelvic separation gradually becomes larger, it will cause local separation. This cannot be ruled out as a genetic factor, and most of it comes from developmental relationships.

The renal pelvis is simply the place where the kidney and ureter connect. Renal pelvic dilatation and separation is caused by kidney stones and ureteral malformations, which prevent urine from being discharged normally, causing the renal pelvis to become filled and enlarged. Renal pelvic separation can also occur when the fetus is holding back urine.

Generally speaking, if the renal pelvis separation does not exceed 10mm, it is within the normal range. If the fetus is not larger than 16mm at birth, there will be no problem. If it continues to grow, regular check-ups and treatment should be considered. You can refer to the following treatments:

(1) Intrauterine treatment: Treatment of hydronephrosis by catheter decompression via uterine puncture

(2) Postnatal surgical treatment: pyeloplasty.

90% of renal pelvis separation occurs in baby boys. For some babies, this problem is solved by peeing when they are born, while for others, due to congenital urinary tract problems (poor urination, backlog in the kidneys), they need surgery to solve the problem.

The symptoms are low amniotic fluid, renal pelvic separation <= 7mm for mild, and renal pelvic separation >= 10mm for severe. However, it is necessary to understand whether the fetal bladder is full. If the bladder is full, it is necessary to wait until the fetus urinates before rechecking. Does the renal pelvic separation gradually increase with the increase of gestational age? Understand whether fetal hydronephrosis develops progressively, the size of the kidneys, and whether the renal cortex becomes thinner. If there is thinning of the renal cortex, it may have a certain impact on the fetus. On the contrary, the impact may not be significant. It should be checked at birth. First, an ultrasound is performed, and if necessary, intravenous pyelography is performed to clarify the kidney function and the location of the obstruction. The operation is somewhat difficult, but it has no impact on the child's life.

Renal pelvis separation is a possible examination result that may appear during prenatal examination of pregnant women. It is normal for the renal pelvis to separate no more than 10 mm. 90% of renal pelvis separation occurs in male babies. For some babies, this problem can be solved by peeing when they are born.

Some babies have congenital urinary tract problems (poor urination, backlog in the kidneys) that require surgery to resolve.
