[Application of buccal mucosa with Snodgrass procedure for repair of hypospadias].

Objective:To present method and experiences in using the buccal mucosa with the Snodgrass procedure for repair of hypospadias. Methods:Between August 2012 and April 2015, 55 boys with hypospadias were treated with Snodgrass procedure combined with buccal mucosa. The age ranged from 1 to 7 years (mean, 4 years). There were 32 cases of distal penile type, 14 cases of proximal penile type, and 9 cases of coronal sulcus type. The buccal mucosa taking from inner cheek was fixed into the incised urethral plate. The urethral plate was tubularized over a catheter. Results:All the patients were followed up 3-25 months (mean, 11 months). After operation, 1 patient had urethral stricture and fistula after repaired urethra was infected, and 5 patients had fistula. For the others, the urination was smooth, the appearance of penis was satisfying, the urethral stricture did not occur, and the penis was straightened completely. Conclusion:Compared with traditional Snodgrass procedure, the application of buccal mucosa can increase the reconstruction material of urethral and reduce the stricture of the repaired urethra after operation.
