Patient's question:
Patient Age: Just born for 2 daysPremature Infant: Bilateral renal pelvis dilatation was detected at 30 weeks of embryonic development: Left 1.1, Right 0.6
After 9 hours of birth (with one urination episode, time of urination unclear), ultrasound revealed the disappearance of right renal pelvis dilatation and left renal pelvis dilatation reduced to 0.242.
Condition of the infant's mother during pregnancy:
1. Had one medication-induced abortion in 2007.
2. Had one stillbirth at full term in January 2009.
3. Became pregnant again in April 2009. In May, iron deficiency anemia was detected. From late July to early August, there was placental membrane separation. After a course of progesterone treatment, the placenta...
Doctor's answer:
Premature newborn: At 30 weeks of embryonic development, bilateral renal pelvis dilatation was found (left 1.1 cm, right 0.6 cm). After 9 hours of birth (with one urination incident, but the time of urination was unclear), a color Doppler ultrasound examination revealed that the right renal pelvis dilatation had disappeared, while the left renal pelvis dilatation was 0.24 cm.Advice: Generally speaking, if there is no dilatation, it may be a congenital developmental malformation. However, it could also be a postnatal change. It is recommended to continue monitoring and perform follow-up ultrasound examinations. It is possible that it may resolve on its own during the next examination. If the condition persists, it may be necessary to investigate whether it is a malformation. Congenital malformations are usually formed during the embryonic period. If it is a congenital malformation, surgery may be an option. The uterus can recover. Currently, the priority is to stop bleeding. If there is significant residual tissue, a uterine curettage may be required, as it may be difficult to control the bleeding otherwise.
