Cohort study on circumcision of newborn boys and subsequent risk of urinary-tract infection

Study published in The Lancet, Volume 352, Issue 9143, Pages 1813-16, 5 December 1998. doi:10.1016/S0140-6736(98)02392-7. The authors interpreted their findings to "support the notion that circumcision may protect boys from UTI, [although] the magnitude of this effect may be less than previously estimated." The study found that "195 circumcisions would be needed to prevent one hospital admission for UTI in the first year of life."
