NAZER H, Julio; CIFUENTES O, Lucia  y  RAMIREZ R, Constanza. Urinary malformations among newborns: ECLAMC Registry, 1998-2010. Rev. chil. pediatr. [online]. 2011, vol.82, n.6, pp.512-519. ISSN 0370-4106.  http://dx.doi.org/10.4067/S0370-41062011000600005.

Introduction: Congenital abnormalities of the Urinary Tract are frequent and prevalence has increased since the introduction of routine prenatal sonogram. Objectives: To determine the prevalence rate of congenital urinary malformations at birth at Hospital Clínico de la Universidad de Chile. These data will be compared to other chilean hospitals participating in ECLAMC (Estudio Colaborativo Latino Americano de Malformaciones Congénitas - Latin American Collaborative Study of Congenital Malformations). A longitudinal study will serve to evaluate if significant variation has occurred, and risk factors will be investigated. Patients and Methods: All births occurring between January, 1998 and December, 2010 were included. Prevalence rate of urinary malformations were calculated, and compared to those obtained in previous years. Statistical analysis of proportions was calculated through mean and average comparison was made through Student t test. Results: Urinary anomalies appeared at a rate of 64.5 per 10.000 births. This represents a significant increase from previous studies. Highest risk factor seemed to be "other family members with disease". Most frequent anomaly was Hydroureteronphrosis (24,2%) followed by Hypospadias (17%). The rate of these malformations in ECLAMC participating Chilean hospitales was 23.37/10.000 births. Conclusion: A significant increase in the diagnosis of these anomalies was shown, being the most important risk factor the presence of family members with similar congenital disorders.
