In a study of ritually circumcised Jewish male neonates, there was a high prevalence of UTI, suggesting that the procedure puts the infants at an increased risk of UTI[

Furthermore, no effect on the incidence of postoperative UTI was found with circumcision performed during anti-reflux surgery[25].
To clear the confusion, a meta-analysis of 12 studies on circumcision and UTI prevention was conducted and, although the procedure seemed to be more beneficial to boys with recurrent UTI (only 11 needed to prevent 1 UTI) and boys with grade III or more VUR (four needed to prevent one UTI), it was calculated that overall, 111 circumcisions would be required to prevent one UTI, costing £55000 in the United Kingdom. The study concluded that a decision to carry our routine circumcision for normal boys with no risk factors was not supported by that meta-analysis[26].
