If a problem is detected in the prenatal period, its possible cause, prenatal and postnatal risks and additional anomaly should be investigated.
Factors determining the course of hydronephrosis; time of occurrence of hydronephrosis in pregnancy (<24 weeks worse), severity/grade of hydronephrosis (bad if cortical parenchyma is thin), and cause of hydronephrosis (bad if the anomaly is bladder and below). Since it does not show any symptoms, it can be sent home without any examination. When the disease gives symptoms, often serious damage has developed. Therefore, prenatal diagnosis is very important. Thus, serious risks can be reduced by taking precautions in the early postpartum period.
Severe problems in both kidneys, severe hydronephrosis or a large bladder (megamesane/megasist) should be taken seriously at all stages of pregnancy. The kidneys may deteriorate and the uterine fluid in which the baby floats may decrease. This is a serious condition and the child's lung and kidney development is impaired. Although rare, it can lead to consequences that progress to stillbirth or endanger the life of the baby immediately after birth. Prenatal intervention may be beneficial in anomalies such as exploding excessive swelling of both kidneys, especially in fetuses with severe progressive and bilateral urinary system obstruction accompanied by oligohydramnios.
In the prenatal period, a probe is placed between the mother's uterus and the baby's bladder, so that the urine from the bladder is emptied into the mother's uterus. In this way, complications that may occur in the urinary system and lungs are reduced, and babies can be delivered without death or permanent damage to the fetus and urinary organs.
Irrespective of the severity of hydronephrosis, it should be a standard approach to deliver the baby vaginally at the usual time due to the severe lung development deficiency associated with preterm birth.
