Patient's question:
Premature Baby: 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 episode of urination, time of urination unclear), a color Doppler ultrasound revealed resolution of right renal pelvis dilatation and a residual left renal pelvis dilatation of 0.24 cm.2. The mother's pregnancy history:
1. Had a medication-induced abortion in 2007.
2. Experienced a full-term fetal stillbirth in January 2009.
3. Became pregnant again in April 2009. In May, anemia was detected, and from late July to early August, there was placental membrane separation. After a course of progesterone treatment, the placental membrane separation resolved. On December 1, 2009, at 1:45 AM, the baby was born prematurely. The attending physician noted that the placenta was sticky and there were residual placental tissues in the uterus.
Gestational age: 30–33 weeks. The cause was unknown.
Doctor's answer:
Based on your detailed information and the ultrasound examination, it is considered that there should be no congenital developmental abnormalities. The renal pelvis, calyces, and fat tissues are collectively referred to as the collection system on ultrasound or color Doppler ultrasound, appearing as strong echoes. Generally, ultrasound focuses on analyzing whether there are changes in hydronephrosis by measuring the distance of low echoes (liquid) within the collection system. Under normal circumstances, the separation is usually less than 10 mm. According to the color Doppler ultrasound examination after 9 hours of birth (with one urination during this period, the time of urination is unknown), the right renal pelvis separation disappeared, while the left renal pelvis separation was 0.24. This indicates that it is normal, and there is no need to be anxious.Regarding the uterine condition, it generally can recover. It is considered that a uterine curettage may be necessary to clear any residual tissue, along with hemostatic, anti-inflammatory, and fluid replacement treatments. Appropriate use of hormones to regulate the endometrium can help improve the condition.
Pay attention to gynecological hygiene and change underwear frequently. Also, ensure warmth, moderately enhance nutrition (especially consuming more protein-rich and blood-boosting foods), and supplement vitamins, trace elements, calcium, iron preparations, etc. Regular follow-up visits are recommended.
