Congenital anomalies of kidney and urinary tract (CAKUT) and associated extra-renal anomalies in fetal autopsies

Le résumé fourni par la source

OBJECTIVES AND BACKGROUND: According to studies, 1% of all pregnancies have an abnormality, with 20-30% of those affecting the genitourinary system. Congenital abnormalities of the kidney and urinary tract (CAKUT) is one of the primary causes of perinatal and neonatal mortality in children. Many extra-renal congenital illnesses accompany these defects, affecting the patient's prognosis. This study aims to determine the subtypes, frequency, and extra-renal defects associated with congenital anomalies of the urinary system, which is the major cause of mortality in fetal and infant autopsies throughout the perinatal and neonatal eras. We believe that our study will contribute to the literature because few autopsy investigations can give this data. MATERIALS AND METHODS: The study included 110 fetal autopsies between January 1997 and May 2019. 10% were newborns under the age of one year, and 90% were fetus autopsies. RESULTS: Males accounted for 67.3% of the cases, while females accounted for 35 (31.8%) (the gender of one case could not be determined). Renal dysplasia was the most frequent CAKUT, with a rate of 22.73%, followed by renal agenesis, with a rate of 20.0%. Eighty-four cases (76.3%) showed disease in at least one other organ system. Musculoskeletal system (MSS) abnormalities were the most common associated system anomaly, with one or more MSS anomalies (34.55%) detected in 38 cases. CONCLUSION: Finally, we want to underline that CAKUT and its associated anomalies are not uncommon. Prenatal imaging, genetic investigation, and/or postmortem examination should all be used to screen for CAKUT. This information is helpful for the mother's future pregnancy management and parental genetic counseling.
