To the Editor.
—Drs Spach, Stapleton, and Stamm1 reported in the February 5 issue of The JOURNAL that "lack of circumcision increases the risk of urinary tract infection [UTI] in young men." Although their series was controlled within their population sample, it is not representative. Each of these men presented at a sexually transmitted disease clinic. This means that each person who presented had urinary symptoms whether or not they were circumcised. It would be better had the authors' conclusion read "lack of circumcision increases the risk of urinary tract infection in young adult males who present to sexually transmitted disease clinics."
