DURAN ALVAREZ, Sandalio et al. Progress of children with urinary tract anomalies and proposal of pregnancy cessation. Rev Cubana Pediatr [online]. 2014, vol.86, n.1, pp.77-85. ISSN 0034-7531.

Introduction: prenatal ultrasound diagnosis performed in normal pregnancies has shown that one significant urinary tract anomaly occurs per 500 pregnancies. Under different circumstances, termination of pregnancy may be suggested or recommended, which may be accepted or rejected by parents. Objectives: to compare the pre-and postnatal diagnoses, and to assess the progress in 8 patients who were recommended to terminate their pregnancies, but they rejected this idea. Results: in 6 cases, the termination of pregnancy was suggested on account of bilateral hydronephrosis diagnosis in their fetuses; in one case due to bilateral renal cysts diagnosis and in the other case due to unilateral hydronephrosis and contralateral multicystic renal dysplasia. There was full agreement between the prenatal and postnatal diagnoses in 2 newborns; in a neonate with high grade reflux, the prenatal study revealed bilateral ureterohydronephrosis whereas this study showed just hydronephrosis for other two fetuses. One patient has non-obstructive bilateral megaureter and the other presents bilateral pyelectasy. The fetus with bilateral renal cysts presented, according to the postnatal study, a double right excretory system, being the upper obstructed and the lower with grade III vesicoureteral reflux, but his left kidney was normal. In the follow-up period, the medical behavior varied according to the postnatal diagnoses. Upon finishing this period, one patient had phase III chronic renal disease and the other seven had preserved renal function. Conclusions: the indication of termination of pregnancy based on the prenatal ultrasonographic diagnosis of a renal or urinary tract anomaly has an error index that must be further studied, and it is necessary to look for high life risk indicators because the predictive factors are not well detailed.
