What are the symptoms of hydronephrosis in pregnant women? Three aspects will tell you

Hydronephrosis during pregnancy is caused by blockage of the ureter, which prevents normal urination, so urine is stored in the kidneys. Hydronephrosis during pregnancy has certain manifestations, such as reduced urination and pain, so pregnant mothers must improve their knowledge.

1. One is that there are ureteral stones or ureteral stenosis before pregnancy , and the hydrops worsens or remains unchanged after pregnancy. The other is that after pregnancy, due to the increase in progesterone levels in the body, the tension of the ureter decreases and the peristalsis weakens. In addition, the enlarged uterus presses on the ureter at the first lumbar vertebra, causing varying degrees of obstruction.

2. Fetal pressure during pregnancy is a common cause of hydronephrosis in women. Because the fetus is in the uterus, it will inevitably press on the kidneys of women, causing hydronephrosis in pregnant women. Mild hydronephrosis is common during normal pregnancy, and it will disappear after delivery.

3. Pregnant women with hydronephrosis can be divided into two types: one is physiological hydronephrosis and the other is pathological hydronephrosis. Most cases of hydronephrosis in pregnant women are physiological, and the pain is generally not obvious, and the pain often occurs on the right side, while the pain of pathological hydronephrosis is strong.
