Will the fetus have renal pelvis separation?

If the fetus does not develop well or the mother does not take proper care of it, the fetus will show symptoms of renal pelvic separation. This symptom usually causes the patient's urine to be unable to be excreted normally, so if such a problem is detected, it must be treated in a timely manner. Specific treatment methods include: knee-chest position, laser irradiation or moxibustion on the Zhiyin acupoint, manual inversion and lateral position, and external fetal rotation.

1. Will the fetus have renal pelvis separation?

Yes. Fetal renal pelvis 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 holds urine.

2. Symptoms of fetal renal pelvis separation

Generally speaking, if the renal pelvis separation does not exceed 10mm, it is within the normal range. If the fetus is no larger than 16mm at birth, there will be no problem. If it continues to grow, regular check-ups and treatment should be considered. The following treatments can be used as reference: (1) Intrauterine treatment: Transuterine puncture and catheterization for decompression to treat hydronephrosis (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.

3. Treatment Methods

(1) Kneel on the bed with your legs shoulder-width apart, with your knees at a 90-degree angle to the bed. Press your chest down as close to the bed as possible and raise your hips as high as possible. Do this position in the morning and before going to bed on an empty stomach, depending on how long you can stand. Try to do it for 15-20 minutes each time.

(2) Laser irradiation or moxibustion at the Zhiyin acupoint : Laser irradiation or moxibustion at the Zhiyin acupoint (0.3 cm beside the outer corner of the toenail of the little toe) is used once a day for 15 to 20 minutes each time. A course of treatment lasts for 5 to 7 days.

(3) Others : manual inversion, side-lying position, etc. Sticking to the left side sleeping position is also very helpful for the baby's turning position.

(4) External fetal position rotation : If the above methods are ineffective and there is no umbilical cord around the neck, external fetal position rotation can be performed at 32 to 34 weeks of pregnancy. External fetal rotation has the risk of inducing premature rupture of membranes, placental abruption, umbilical cord entanglement and premature birth, so it should be used with caution. The pregnant woman should lie flat on her back with both lower limbs flexed and slightly abducted to expose the abdominal wall, check the fetal position and listen to the fetal heartbeat. First, loosen the fetal presenting part. That is, the operator inserts both hands under the fetal presenting part and pulls it upward to loosen it, and then rotate the fetus.
