Preputial bacterial colonisation in uncircumcised male children: Is it related to phimosis?

Objective: to evaluate the presence of uropathogens in the periurethral skin and the effect of phimosis on bacterial colonisation. methods: the observational cohort study was conducted in samsun research and training hospital,samsun,turkey from june to december,2014,and comprised patients undergoing circumcision. before circumcision,all children were examined in the operating room and the presence of phimosis was recorded. all patients had circumcision performed by the same surgical team under general anaesthesia. before the procedure,samples were taken from preputial skin of all patients by swab before cleansing with polyvidone-iodine. the samples were inoculated on 5% sheep blood agar and eosin-methylene blue agar. results: themedian age of the 117 children was 5 years (range: 1-12). of the total,19(16.2%) children had complete phimosis,and 72(61.5%) had partial phimosis. in all,91(77.7%) children had phimosis and 26(22.3%) had no phimosis. of the 91 patients with different degrees of phimosis,52(57.1%) had clinically significant uropathogenic bacterial colonisation >100,000 colony-forming units per millilitre [cfu/ml]). of the 26 patients without phimosis,13(50%) had clinically significant colonisation. thus,there was no effect of the presence of phimosis on bacteria colonisation (p=0.655). conclusions: important uropathogens colonise the preputium in uncircumcised male children. there was no effect of phimosis on colonisation. © 2016,university of economics - prague. all reserved.
