What does fetal renal pelvis separation mean?

Renal pelvis separation usually occurs when kidney stones appear, causing urine to accumulate and be unable to be excreted, so that the renal pelvis will gradually swell and enlarge. In fact, this situation is quite common, but many pregnant women don’t know much about it. In the case of fetal renal pelvis separation, the pregnant mother can perform some limb exercises to treat or relieve it. If the fetus needs to take medication, the side effects will only be greater. What pregnant women need to do is to have regular prenatal checkups and resolve any problems with the fetus in a timely manner.

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 is holding back urine.

Basic Definition

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 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.

Treatment

If shoulder presentation is found in the late pregnancy, the correction method is the same as breech presentation. If it is ineffective, external version can be tried to change to head presentation and the abdomen can be bandaged to fix the fetal head. If it fails, the patient should be hospitalized in advance to prepare for delivery. The correction method is as follows:

(1) Knee-chest position: after 30 weeks (7.5 months) of pregnancy

Method: Kneel on the bed with legs shoulder-width apart, with knees at a 90-degree angle to the bed. Press the chest down as close to the bed as possible and raise the hips as high as possible. Do this for 15-20 minutes each time when you wake up in the morning and before going to bed on an empty stomach, depending on how long you can bear.

This method uses the change in the fetal center of gravity and the lateral resistance of the pregnant woman to increase the chance of the fetus turning to a head position. One course of treatment is 7 days. If it is unsuccessful, it can be continued for another 7 days. The effective rate is 60%-70%. A small number of pregnant women experience dizziness, nausea, and palpitations when doing the knee-chest position and cannot persist. In this case, other methods need to be used to correct the fetal position.

Serious attention : When the fetus turns, the umbilical cord may be wrapped around a part of the fetal body or even strangle the neck, causing fetal hypoxia and abnormal fetal movement. Therefore, it is necessary to conduct weekly check-ups under the guidance of a doctor to monitor the fetal heart rate and record and compare abnormal fetal movements.

(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.
