Objective
Redundantprepuce and phimosis are known risk factors for balanoposthitis. It is usuallycaused by retrograde infection and is related to the preputial bacterial flora.We investigated differences in the preputial bacterial flora between patientswith balanoposthitis and physiological phimosis.

原文：Materialsand MethodsFifty-sixmale children were included in the study. Fifteen patients presented to theemergency room or outpatient department with balanoposthitis. Forty-onepatients with physiological phimosis received a circumcision. Preputialswab cultures were done. Differences in age, body weight, andpreputial flora between these two groups of patients were compared.

材料和方法
本研究包含56名患儿，15名患儿因包皮龟头炎就诊急诊室或门诊，41名患儿因生理性包茎接受了包皮环割手术。均进行包皮的拭子培养。比较分析这两组患儿之间的年龄、体重以及包皮菌群的差异。

Results
Patientswith balanoposthitis in this study were significantly younger. Commonuropathogens were predominant in patients with balanoposthitis, whereas inpatients with physiological phimosis, the main isolates were enteric floraother than common uropathogens. Patients with a body weight higher than the50th percentile of the normal growth curve had a lower risk of balanoposthitis(odds ratio = 0.212).

研究结果

Conclusions
Thepreputial bacterial flora in patients with physiological phimosis may changefrom enteric flora to common uropathogens which are predominant in patientswith balanoposthitis. Furthermore, patients at a younger age and with a lighterbody weight also had increased susceptibility to balanoposthitis.

结论
生理性包茎患儿的包皮细菌群可由肠道菌群向普通尿道病原菌转变，该菌群为包皮龟头炎患儿的主要病菌。此外，年纪较小和体重较轻的患儿易患包皮龟头炎。
