[Application of disposable oval circumcision anastomat in pediatric urology].

To summarize the application experience of Ai Tong (Chinese Shang Ring) disposable oval circumcision anastomat in pediatric urology. A retrospective study of 1 481 cases of pediatric urology using a disposable oval circumcision anastomat at Xuzhou Children's Hospital from October 2014 to December 2017 was performed. The average age at the time of surgery was 5.2 (2-14 years) years. Among them, there were 1 226 cases of phimosis, 32 cases of scar phimosis in chronic infection, 23 cases of phimosis or redundant prepuce with urethral duplication, 29 cases of foreskin trauma, 35 cases of phimosis or redundant prepuce with urethral cyst, 3 cases of phimosis or redundant prepuce with urethral stricture, 108 cases of phimosis or redundant prepuce with webbed penis, 6 cases of phimosis with penile downward bending, 4 cases of phimosis with short frenulum preputii, and 15 cases of relatively normal foreskin development, I° and II° hypospadias with unapparent penile downward bending, and megalourethra with complete foreskin hypospadias. All operations were completed successfully. The postoperative circumcision time was less than 5 days on 2 cases(0.1%), and was longer than 25 days on 9 cases(0.6%). The average postoperative circumcision time was 13.2 days. During a follow-up period of 3 months, except for 2 cases (0.1%) of frenulum preputii edema, all other cases had a satisfactory foreskin appearance. They had no obvious foreskin scar hyperplasia, the foreskin cutting edge was neat, the foreskin ligament was intact, the foreskin was left and right symmetrical, and the foreskin was preserved in the absence of erection to cover the coronary sulcus to 1/3 of the glans. All children with hypospadias had no urethral stricture and urethral fistula, and the penis was satisfactory. Ai Tong (Chinese Shang Ring) disposable oval circumcision anastomat is satisfactory in the treatment of various diseases of pediatric urology. With a low incidence of postoperative complications, it may be easy to carry out this procedure at grass-roots hospital.
