Liu Chunxi, an expert in special needs clinic of Shanghai Jiangdong Hospital, said: Hypospadias surgery is strictly a kind of plastic surgery in urology, with high accuracy and great difficulty in actual operation. It is so difficult to urinate after operation, which shows that urethral stricture is serious and urethral dilatation cannot be solved, so it needs reoperation. Dysuria caused by urethral stricture has a bad effect on the proximal urinary tract. Urethral stricture and urinary fistula can be cured by one operation. Shanghai Jiangdong Hospital is a characteristic hospital of hypospadias. He signed a contract to ensure that the success rate of staged surgery was higher than 95%, and refused to urinate after operation.
