Perfil epidemiológico da hipospádia na região Bragantina do estado de São Paulo, Brasil

Abstract

Study model: a Prevalence study. Objective: Evaluating the epidemiological profile of hypospadias cases assisted in the Hospital Sao Francisco na Providencia de Deus of the Universidade Sao Francisco (HUSF), Braganca Paulista, Brazil, in the last 10 years (2007-2017), relating the types of hypospadias with associated malformations and age at the first corrective surgery. Methodology: A survey of hypospadias cases assisted between 2007 and 2017 in HUSF was carried out with patients from the Bragantina region of the state of Sao Paulo. The types of hypospadias were related to the associated malformations. The following data were collected from the medical records: type of hypospadias, age at first surgery, ultrasound imaging, ethnicity, place of birth, associated malformation. Data were statistically analyzed using Chi-squared, F-test and Kruskal-Wallis tests. Results: In 1401 pediatric assistances, it was found 45 cases of hypospadias with a prevalence of 0.7/1000 births. From the total, 29 cases were classified as distal, six cases of medium, and 10 cases as proximal types [F-test (2.8)=5.552, P=0.003, χ2=9.3117, P=0.009]. Cases of distal hypospadias had 16 associated malformations, and for medial and proximal types there were seven associated malformations in each one (KW=3.322, P=0.19). The largest number of cases was surgically corrected between three and four years of age. Conclusion: Distal hypospadias were the most prevalent in the Bragantina region in the last 10 years. It was also observed that the age at first surgery is in disagreement with the range proposed for the corrective approach of hypospadias.
