Prenatal Diagnosis of Reno-Urinary Malformations in a Tertiary Center of Republic of Moldavia

Abstract

Malformative uropathy in children is one of the most common pathological conditions, with an incidence of 5–14% in newborns. Recent research shows that even in the current conditions, they are often diagnosed only in the advanced stages, when Chronic Kidney Disease is already affirming. This study’s objective is to identify urinary tract anomalies, including malformative uropathies in the prenatal stage, using imaging techniques, namely ultrasound of the pregnant uterus. Using prenatal ultrasonography of the pregnant uterus and postnatal clinical and paraclinical examination, we prospectively evaluated a cohort of fifty children with pyelectasia. We describe the demographic and pathological characteristics of patients diagnosed with renal–urinary abnormalities, as well as their postnatal management. A prenatal diagnosis made during the first 15 to 22 weeks of pregnancy enables the evaluation of early malformative uropathies and the determination of the best time to operate in order to minimize complications. When prenatal ultrasonography, fetal karyotype, tissue sample, and embryonic appendages work together, problems may be partially or entirely revealed by these methods due to mistakes made in imaging examinations. In the case of a pregnancy with an antenatal malformation detected, it is necessary for the delivery to take place in a clinic that can provide favorable services for the survival and investigation of the child born with malformative abnormalities.
