“…Some authors have demonstrated that covering the first suture line with single or double dartos flap or spongioplasty may decrease the incidence of fistula development [5,6,7,8,9]. Others have demonstrated some benefits with the use of fibrin glue as a sealant for urethrocutaneous fistula prevention after hypospadias repair and for the closure of fistulas [10,11,12]. However fibrin sealants from a single-donor or multiple donors have some risks of HCV, HBV or HIV contamination, may sometimes lead to a severe allergic reaction, and are also expensive [13,14].…”
