Objective To explore the effect of family-centered education using mind mapping technique in children undergoing hypospadias surgery. Methods A total of 154 children undergoing hypospadias surgery were chronologically assigned to a control group (n=77) or an intervention group (n=77), receiving either standard family-centered education or tailored, family-centered education intervention using mind maps. Results The intervention group reported better quality of discharge teaching and higher satisfaction with the education, whereas lower incidence of postoperative adverse events （catheter blockage, catheter dislodgement, and urinary fistula） compared with the control group （all P＜0.05）. Conclusion The use of mind maps in family-centered education can effectively improve family ability of caring for children undergoing hypospadias surgery, reduce the incidence of postoperative adverse events, and enhance quality of care.
