Buccal mucosa urethroplasty: a 10-year retrospective review of maxillofacial and urological outcomes

[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.
