Abstract：Objective: To summarize the operative key points of hypospadias in perioperative period and discuss the precautions for prevention and control of surgical complications. Methods: A total of 156 patients with hypospadias admitted to our urology department from January 2013 to December 2017 were selected as research objects. During the operation, penile bending and urethral plate development were assessed by artificially induced erection, and stage I or stage I operations were performed. The surgical plan was based on urethral plate-based urethral reconstruction technology. Results: There were 123 cases of 156 patients undergoing one stage operation and 33 cases undergoing stage operation. Sixty-seven patients underwent one stage operation and 28 patients underwent stage operation for the first time. Fifty-six patients underwent one stage operation and five patients underwent staging operation. Twenty-one cases of moderate curvature received dorsal penile fold correction, and all cases of severe curvature received dorsal penile fold correction. During the postoperative follow-up period of 6 months to 1 year, there were 11 cases of urinary fistula (7.1%) and 14 cases of urethral stricture (8.9%) [including 6 cases of anastomotic stricture (42.9%) and 8 cases of external urethral stricture (57.1%)]. Sixteen cases (10.3%) were accompanied by downward curvature of the penis, and the degree of penile bending was less than 15°. Conclusion: To evaluate the types of hypospadias and the development of penis comprehensively, choose reasonable operation methods, and master the key points of operation can effectively improve the success rate of hypospadias.
