Is there a correlation between hypertrophic pyloric stenosis and congenital abnormalities of the urinary tract in children?

Abstract

Aim-Background: Numerous clinical associations and congenital abnormalities have been described in combination with hypertrophic pyloric stenosis (HPS) in infants. The correlation between HPS and congenital abnormalities has not yet been clarified. The aim of this study is to assess whether there is a common appearance of these two conditions and whether an extra testing of the urinary tract is needed. Patients and methods: Fifty-six children who had undergone surgery for HPS between 2001 and 2005 were retrospectively evaluated. History was obtained and ultrasound screening of the urinary tract was performed. Results: The ultrasound screening revealed a double renal pelvis system in one boy (1.7%). Twelve (21%) children had an incidence of urinary tract infection (UTI) and two boys (3%) had a positive history for nocturnal enuresis. There is no correlation between hypertrophic pyloric stenosis and congenital abnormalities of the urinary tract, since the difference between the incidence of congenital malformations of the urinary tract in the general population and the population with HPS is insignificant. Conclusion: We do not recommend additional testing of the urinary tract in children with HPS, but more research is required to establish whether there are functional disorders of the urinary tract in the population with HPS.
