Background: congenital defects of the kidney and urinary ducts are frequent developmental anomalies in man, leading to 30-50 % of end-stage renal failure. Its early diagnosis and treatment are important to minimize kidney damage.
Objective: to describe the results of the prenatal diagnosis of congenital defects of the kidney and urinary ducts, by using ultrasonography, in Las Tunas from January 2011 to December 2016.
Method: a retrospective and descriptive study was performed on the results of the diagnosis of congenital defects of the kidney and urinary ducts through the provincial register of congenital malformations. The following variables were analyzed: prevalence of renal congenital defect and its ducts, area of origin, age groups, trimesters of pregnancy and morpho-functional classification of the anomaly. The results were analyzed according to descriptive statistics.
Results: the prevalence of renal and urinary ducts defects was 3.9 x per 1000 live births (LB), with a higher number of cases in 2016 (5,4 x 1000 LB). The municipality of Las Tunas showed the highest number of defects (43). In pregnant women, the 20 to 34 age group prevailed with 109 cases (75,1 %). In the second trimester of pregnancy, the most representative casuistry was diagnosed (100). Follow-up prevailed over interruptions of pregnancy. There was no substantial difference between the number of renal defects (72) and that of the urinary ducts (73).
Conclusions: the study found a high prevalence of anomalies in the kidney and its ducts. Their diagnoses were possible by using ultrasonography, which is a useful prenatal diagnostic tool.Downloads
