Maternal Risk Factors for Infants Born with Congenital Renal and Urinary Tract (CAKUT) Anomalies: A Cross-Sectional Assessment.

Abstract

Congenital Anomalies of the Kidney and Urinary Tract (CAKUT) often results in renal failure. Alhough the pathophysiology of CAKUT is still not completely understood, several maternal risk factors have been identified associated with children with CAKUT so far. Therefore, the aim of this study was to assess the proportion of risk factors of mothers gave birth to the infants with CAKUT. This cross-sectional study was conducted over a six-month period in the Departments of Pediatrics, Pediatric Nephrology, Neonatology and Pediatric Urology in Dhaka Shishu Hospital, Bangladesh from May 2018 to November 2018. A total of 200 infants aged ≤60 days and with a confirmed diagnosis of CAKUT were included in this study. Informed ascend was taken from the parents of the child. A semi-structured questionnaire was used for data collection, and statistical analysis was performed using SPSS version 21.0. This research was undertaken in conjunction with the ethical principles of Declaration of Helsinki. The mean age of the infants with CAKUT was 22.25±15.08 (SD) days with a male to female ratio of 1:1. The presenting anomalies were primary vesico-ureteral reflux (38.0%), pelvi-ureteric junction obstruction (20.0%), agenesis of the kidney (16.0%), posterior urethral valve (12.0%), dysplasia of the kidney (10.0%) and multicystic dysplastic kidney (3.5%). The most common pregestational risk factors were overweight (76.0%), diabetes mellitus (32.5%) and hypertension (29.5%) among the mothers. On the other hand, oligohydramnios (87.5%), gestational diabetes mellitus (67.0%) and gestational hypertension (45.5%) were the most frequently identified gestational risk factors. Pregestational overweight in women, maternal diabetes and oligohydramnios were most commonly identified risk factors among the mothers of CAKUT infant.
