摘　　要：BACKGROUND Complex hypospadias is a surgical challenge.AIM To present the long-term outcomes of two-stage repair of complex hypospadias using a scrotal septal flap.METHODS This was a retrospective study of patients with complex hypospadias who were operated on between January 1st,2001,and January 1st,2019,at a single hospital using a scrotal septal flap(two-stage surgery)or prepuce flap(one-stage surgery;control group).In the scrotal group,the urethra was first repaired using oral mucosa;in the second stage,a scrotal septal flap was used as a second impermeable layer.Maximal/average urinary flow rates after surgery were compared.All patients were followed for≥6 mo(range:6-96 mo).RESULTS Ninety-seven patients were included(46 in the scrotal group and 51 in the prepuce group).The maximal urinary flow rate was 15.4±2.1 mL/s in the scrotal group and 14.3±3.0 mL/s in the control group(P=0.035).The average urinary flow rate was 8.4±2.3 mL/s in the scrotal group and 7.5±1.5 mL/s in the control group(P=0.019).The proportion of patients achieving good therapeutic effects was higher in the scrotal group than in the control group[24(52.2%)vs 16(31.4%),P=0.042;34(73.9%)vs 25(49.0%),P=0.014].The scrotal flap two-stage surgery was independently associated with a higher maximal urinary flow rate(OR=2.416,95%CI:1.026-5.689,P=0.044)and with a higher average flow rate(OR=2.484,95%CI:1.054-5.854,P=0.038).CONCLUSION In complex hypospadias,a scrotal septal flap could be a versatile and reliable option for resurfacing the penis.
