Objective: The aim is to evaluate the complications in patients who are circumcised before school age and investigate the effect of diaper use on complications of circumcision. Method: 1,669 cases between 20 days and 7 years of age who were circumcised under local anaesthesia were investigated retrospectively. The patients were divided into two groups. Group 1 consisted of those who used diapers, and group 2 consisted of those who did not use diapers. Those who were operated due to urogenital pathologies and simultaneously circumcised were not included in the groups. The children who normally used diapers continued to be diapered following circumcision. Results: The most common complication following circumcision was bleeding (2.9%). Other complications included infection (2.2%), ecchymosis (2.3%), skin adhesion (1.3%), urinary retention (0.1%), redundant foreskin/circumcision revision (0.1%), and meatal stenosis (0.1%). Bleeding, infection, ecchymosis, skin adhesion, urinary retention, redundant foreskin-circumcision revision and meatal stenosis rates did not vary significantly (p>0.05) between group 1 and group 2. Conclusion: Diaper use was not found to have any effect on complications of circumcision.
