Further analysis of the Glans-Urethral Meatus-Shaft (GMS) hypospadias score: Correlation with postoperative complications

The Glans-Urethral Meatus-Shaft (GMS) classification provides a means by which hypospadias severity and reporting can be standardized, which may improve inter-study comparison of reconstructive outcomes. There is a strong correlation between complication risk and total GMS score. Degree of chordee (S score) is independently predictive of fistula rate.
