What Does It Mean by "Bilateral Renal Pelvis Separation" on a Pregnancy Test?
During pregnancy examination, the so-called bilateral renal pelvis separation mainly refers to the distance between the fallopian tube and the kidney connection. In addition, when examining the fetus, the fetus may also have renal pelvis separation. Generally, the separation distance of the fetus within 1.6cm is considered normal, but if the separation distance is significantly too large, it is considered that there is a high probability of a lesion, and appropriate treatment should be identified as early as possible. The renal pelvis is actually the place where the kidney and ureter are interconnected. Under normal conditions, the residual separation will not exceed one centimeter. When the renal pelvis separation of a newborn child is not greater than 1.6 centimeters, it is also within the normal range, and no major health problems will occur.
What Does the Separation of Bilateral Renal Pelvis in Pregnancy Examination Mean?
1. Bilateral renal pelvis separation of the fetus suggests the possibility of developmental malformation of the fetal urinary system. Under normal conditions, there is a certain degree of separation between the bilateral renal pelvis of the fetus, which generally does not exceed 10 mm.
2. If the separation range is between 10-15 mm, it may indicate the presence of hydronephrosis; if the separation range is above 15 mm, hydronephrosis is diagnosed, which is generally considered to be caused by congenital developmental malformation of the urinary system. In this case, further examination is needed to make a definite diagnosis, evaluate the impact on the fetus's health after birth based on the specific situation, and make reasonable treatment decisions.
(1) Intrauterine treatment: decompression treatment of hydronephrosis by uterine puncture and catheter placement;
(2) Surgical treatment after birth: pyeloplasty.
