A '''urinary tract infection''', also commonly known as a '''UTI''', is a bacterial [[infection ]] in the urinary tract (kidneys, ureters, bladder and/or [[urethra]]). UTIs can affect both males and females, although, due to the difference in structures of the male and female urinary tract, infections occur most commonly in girls and women, as the urinary tract is shorter in females than it is in males. UTIs can become serious if undetected, and may lead to permanent kidney damage. However, they are easily and effectively treated with antibiotics.<ref name="ginsburg uti" >{{REFjournal |last=Ginsburg |init=CM |last2=McCracken |init2=GH |url=http://www.cirp.org/library/disease/UTI/ginsburg/ |title=Urinary tract infections in young infants |journal=Pediatrics |date=1982 |volume=69 |pages=409-412}}</ref><refname="McCracken 1989">{{REFjournal |last=McCracken |init=GH.

UTIs are often caused by ''Escherichia coli'' (E. coli) bacteria, to which the infant has no passive immunity. In infant girls UTIs generally originate in the colon, whereas in infant boys they originate from the external environment, strongly suggesting that for boys such infections [[infection]]s are [[iatrogenic]].<ref>{{REFjournal |last=Maskell, |init=R.

Whether intact or circumcised, baby boys sitting in poopy diapers allows ''E. coli'' an opportunity to enter the urinary tract. And, of course, fiddling with the [[foreskin]] and introducing bacteria foreign to the baby's body or his urinary tract can also cause UTI. The tight foreskin of the infant boy acts as a sphincter to allow [[urine]] to flow out, but prevents contaminants and pathogens from coming in.<ref name="Fleiss 1998">{{FleissP HodgesF VanHoweRS 1998}}</ref>

Studies show fairly conclusively that UTIs can be easily prevented. Hospital-borne strains of ''E. coli '' remain the cause of the majority of UTIs, and infection can be resisted by taking certain measures to enhance the immunity of the infant to such pathogens.

In a determined search for an association between the presence of the [[foreskin ]] and UTI, Wiswell et al . (1985) retrospectively examined charts of a number of boys born at U.S. military hospitals.<ref>{{REFjournal |last=Wiswell |init=TE, |last2=Smith |init2=FR, |last3=Bass |init3=JW. |title=Decreased incidence of urinary tract infections in circumcised male infants.

Wiswell's findings generated a great deal of controversy at the time. The prepuce (foreskin) is a protective organ, and one would not normally expect the removal of a healthy organ to reduce the risk of infections.<ref>name="Cunningham N. [http://www.cirp.org/library/disease/UTI/cunningham/ Circumcision and urinary tract infections]. (letter) ''Pediatrics'' 1986; 77(2):267.<"/ref> Nevertheless, the apparent correlation of intact foreskin to bacteriuria (and hence UTI) prompted the American Academy of Pediatrics (AAP) to review the evidence available in 1989.

The problem began with Ginsburg and McCracken's study, which failed to notice that Parkland Hospital had made it hospital policy not to perform non-therapeutic circumcisions in neonates,<ref>{{REFjournal |last=Wallerstein |init=E. [ |url=http://www.cirp.org/library/general/wallerstein/ |title=Circumcision: the uniquely American medical enigma]. '' |journal=Urol Clin North Am'' |date=1985; |volume=12( |issue=1): |pages=123-132.}}</ref> so the majority of its young male client population would have necessarily remained intact. The observation that 95% of the boys were not circumcised, therefore, indicated nothing more than that the majority of male infant patients at Parkland Hospital were not circumcised.

*The parents of some of the intact infants may have been instructed to [[Forced retraction|forcibly retract]] the foreskin and scrub beneath, which would have put the children at a higher risk of infection. The same criticism applies to the later Wiswell studies and other American studies of infant UTI [Herzog, Roscelli] to date: None have taken care to ensure that there was a control group of infants whose foreskins were simply left alone.

*Littlewood (1972) found an association of UTI with maternal infection, perinatal anoxia, and high or low birthweight.<ref>{{REFjournal |last=Littlewood |init=JM. [ |url=http://www.cirp.org/library/disease/UTI/littlewood1/ |title=Infants with urinary tract infection in first month of life]. '' |journal=Arch Dis Child'' |date=1972; |volume=47( |issue=252): |pages=218-26.226}}</ref> Wiswell failed to account for these confounding factors, although they should have been known to him.

*The Wiswell studies considered bacteriuria as diagnostic of UTI. However, a positive [[urine ]] culture alone is not necessarily indicative of symptomatic UTI requiring treatment.<ref>{{REFjournal |last=Schlager |init=TA, |last2=Hendley |init2=JO, |last3=Dudley |init3=SM, |last4=Hayden |init4=GF, |last5=Lohr |init5=JA. |title=Explanation for false-positive urine cultures obtained by bag technique.

*The hospital chart data used in the retrospective studies are unreliable. Hospitals frequently omit to record a circumcision on a baby's chart. In Atlanta, O'Brien found that circumcision was recorded only 84.3% of the time for circumcised boys.<ref>{{REFjournal |last=O'Brien |init=TR, |last2=Calle |init2=EE, |last3=Poole |init3=WK. |title=Incidence of neonatal circumcision in Atlanta, 1985-1986. '' |journal=Southern Medical Journal'' |date=1995; |issue=88: |pages=411-5.415}}</ref> If the records used in the retrospective bacteriuria studies are similarly inaccurate, then a statistically significant number of the infants with bacteriuria that were claimed to be intact were, in fact, circumcised. This would naturally overstate the rate of infection in intact boys.<ref>{{REFjournal |last=Van Howe |init=RS. [ |author-link=Robert Van Howe |url=http://www.cirp.org/library/disease/UTI/vanhowe/ |title=To the Editor], '' |journal=Southern Medical Journal'' (unpublished).}}</ref>

*It is very possible that the use of surgical antiseptic (to kill pathogenic organisms during the circumcision procedure itself) was in part responsible for the slight reduction in bacteriuria observed in these studies. This possibility was not accounted for in the studies.

*No information on rooming-in or breastfeeding history for the infants before they were hospitalized was recorded. [[Breastfeeding ]] and rooming-in are important factors in the prevention of UTI.<ref>name="Winberg J ''et al.'' [http://www.cirp.org/library/disease/UTI/winberg-bollgren/ The Prepuce: A Mistake of Nature?] ''Lancet'' 1989, pp.598-99.<"/ref> (See above.)

*Breastfeeding is a major confounding factor in any study of the role of circumcision in UTI. The Wiswell studies and all other studies in the literature fail to control for the effects of breastfeeding. The AAP observes that "breastfeeding status has not been evaluated systematically in studies assessing UTI and circumcision status."<<ref>name="Sreenarasimhaiah S, Hellerstein S.

Wiswell's sensational statistic, that [[circumcision ]] resulted in a "ten to hundred times decrease in urinary tract infections in circumcised boys," has often been quoted; however, it is misleading. In fact, UTIs are so rare in either case that,even giving Wiswell's data the benefit of the doubt, 50 to 100 healthy boys would have to be circumcised in order to prevent a UTI from developing in only one patient. Using more recent data from a better-controlled study, the number of unnecessary operations needed to prevent one hospital admission for UTI would jump to 195.<ref>{{REFjournal |last=To |init=T, |last2=Agha |init2=M, |last3=Dick |init3=PT, ''et al.''

The American Academy of Pediatrics (AAP) formed a 1989 task force under the chairmanship of the late [[Edgar J. Schoen]] to reconsider its 1975 policy statement. This task force issued a statement in 1989 which cited the UTI papers of [[Thomas E. Wiswell]] as a reason that one might circumcise a child., but it included a disclaimer. The report stated:

It should be noted that these studies in army hospitals are retrospective in design and may have methodologic flaws. For example, they do not include all boys born in any single cohort or those treated as outpatients, so the study population may have been influenced by selection bias.<ref>{{REFjournal |last=Task Force on Circumcision. |title=Report of the Task Force of Circumcision '' |journal=Pediatrics'' |date=1989; |volume=84( |issue=4): |pages=388-91.391}}</ref>

The American Academy of Pediatrics (AAP) has issued two statements which, when read together, constitute a substantial change in AAP policy toward the prevention of UTI in infants. First, in 1997, the AAP Workgroup on Breastfeeding recommended breastfeeding as highly beneficial in preventing a wide range of infections including UTI.<refname="AAP 1997">{{REFjournal |last=AAP Workgroup on Breastfeeding.

'' |journal=Pediatrics'' |date=1997; |volume=100( |issue=6) |pages=1035-1039.}}</ref> Second, in 1999, The 1999 AAP Task Force on Circumcision abandoned the previous stance of the 1989 Task Force on Circumcision that circumcision may provide protection against UTI.<refname="AAP 1999">{{REFjournal |last=AAP Task Force on Circumcision. [ |url=http://www.cirp.org/library/statements/aap1999/ |title=Circumcision Policy Statement]. '' |journal=Pediatrics'' |date=1999; |volume=103( |issue=3): |pages=686-693.}}</ref> The 1999 Task Force found that the bulk of the UTI studies were so methodologically flawed—by failing to control for confounding factors-such as breastfeeding—that no meaningful conclusions could be drawn from them. The 1999 AAP Task Force on Circumcision could not, therefore, recommend circumcision to reduce incidence of UTI (or any other disease).<ref>name="AAP Task Force on Circumcision. [http://www.cirp.org/library/statements/aap1999/ Circumcision Policy Statement]. ''Pediatrics'' 1999;103(3):686-693.<"/ref>

The 1999 AAP Task Force on Circumcision did, however, declare that breastfeeding produces a three fold reduction in UTI in infants. Two separate panels of the AAP, the Work Group on Breastfeeding and the 1999 Task Force on Circumcision, now recommend breastfeeding to reduce incidence of UTI.<<ref>name="AAP Workgroup on Breastfeeding.

''Pediatrics'' 1999;103(3):686-693.<"/ref>

The notion that [[circumcision ]] is a useful prophylactic against UTI has been laid to rest by the 1999 AAP Task Force on Circumcision.<ref>name="AAP Task Force on Circumcision. [http://www.cirp.org/library/statements/aap1999/ Circumcision Policy Statement]. ''Pediatrics'' 1999;103(3):686-693.<"/ref> Instead, healthy, natural alternatives such as [[breastfeeding ]] and rooming-in must be given favor. Breastfeeding offers a wide range of benefits for both mother and baby. Circumcision is surgery, and as such it has attendant risks, which include includes UTI itself.The proper treatment of UTI, if it occurs, is antimicrobial.<ref name="McCracken 1989" />
