From 2014-2017, 29 cases of perineal hypospadias and 60 cases of scrotal hypospadias have been done in my institutions. The ages of the patients ranged from 1 to 10 years (mean=4 years). All children had their urinary catheters removed 4 weeks after the operation. All children had their urinary catheters removed 1, 3, and 6 months, and then reviewed at least once a year for 3 consecutive years. Nine cases of urine leakage occurred within 3 days after the operation. The leakage orifices were all located at the junction of the penis ventral penis and scrotum. The diameter of the leakage orifice was about 2-5mm. One case had urine leakage 3 months after the operation, and 1 case was 5 after the operation. Urine leakage occurred in the first month, and the leakage opening was located in the middle of the ventral side of the penis, with a diameter of about 1mm. It is considered that the needle eye caused the leakage of urine after the absorbable thread was absorbed. One case of urine leakage was caused by skin infection in 1 year after the operation. All the children with urine leakage were repaired after the leakage occurred one year later, and the leakage was successfully repaired at one time. There was no urethral stricture after operation. The one-time success rate of this operation was 87.6% (78/89) and the incidence of urethral fistula was 12.6% (11/89).
