Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? How big is the fetus at 23 weeks of pregnancy?Doctor's answer:
Such issues generally require timely diagnosis based on self-examination results, while maintaining a balanced diet, consuming fresh fruits and vegetables, avoiding spicy foods, drinking plenty of water, getting adequate rest, and supplementing with multiple vitamins for early recovery.Normal fetal kidneys may have mild separation in the collecting system, with a separation diameter of up to 6 mm. However, hydronephrosis is diagnosed when the renal pelvis dilation is ≥10 mm or there is dilatation of the renal calyces after 30 weeks of gestation. Hydronephrosis is classified into two types.
One type is reversible: The hydronephrosis width ranges from 1.01 to 1.63 cm, with relatively thick renal parenchyma (1.02 to 0.58 cm). After birth, changes in the environment cause the hydronephrosis to disappear. This is often seen in cases where the fetal bladder is significantly filled with urine or due to certain causes of ureteral rhythmic contraction dysfunction. In some cases, the ureter may have certain anatomical abnormalities.
The other type is irreversible: The hydronephrosis width ranges from 2.15 to 2.56 cm, with thin renal parenchyma (0.3 to 0.2 cm). This is commonly associated with congenital ureteral stenosis, often accompanied by changes in secretory function, requiring timely treatment after birth.
