Assessment of incidence and risk factors for development of postoperative complications of hypospadias surgery at Aliasghar hospital in 2017

Abstract

Background: Due to the relatively high complications of hypospadias surgery, this survey aimed to resolve the incidence and risk factors for hypospadias surgery complications in children undergoing surgery at Aliasghar hospital in Tehran in 2017. Materials and Methods: This descriptive-analytical study was performed on 90 children over six months who underwent surgical treatment of hypospadias. Information on risk factors was collected by a researcher-made questionnaire at the time of admission and at the time of discharge. Also, surgical complications were evaluated two weeks after surgery and up to one year after that and entered in a questionnaire. Findings were analyzed using t-test and chi-square test or Fisher Exact test. Results: The only surgical complication was urethrocutaneous fistula, which was seen in 18.9% of patients. Risk factors associated with complications of hypospadias surgery include low birth weight, preoperative testosterone injection, presence of penoscrotal or scrotal hypospadias, Ducket`s surgical technique and Prolonged retention of the urinary catheter, but the age of the child at the time of surgery, gestational age, and family history of hypospadias were not associated with surgical complications. Conclusion: It is recommended to be more careful in terms of surgical technique, especially in children with low birth weight and penoscrotal or scrotal hypospadias, and if possible, avoid testosterone before surgery and Ducket`s technique for surgery.
