[Modified Dyplay technique in the treatment of anterior hypospadias. Immediate and long term results in 321 cases and review of the literature].

OBJECTIVES

Description of a surgical technique in the treatment of anterior hypospadias, a frequent malformation for which the treatment is not devoid of complications. Evaluation of the short-term as well as the long-term results.

MATERIAL AND METHODS

Retrospective study of 321 patients treated according to this method. 58 patients were reviewed with a mean follow-up of 71 months.

RESULTS

The immediate results were marked by the development of 16 fistulas (5%), 4 of which closed spontaneously. Five cases (1.6%) of meatal retraction and 6 meatal stenoses (1.9%) were observed. The overall complication rate requiring specific treatment was 5.6%. The long-term results showed meatal retraction in 20.7% of cases, meatal stenosis in 1.7% of cases and fistula in 3.5% of cases. This is the series with the longest mean follow-up. Comparison with the currently proposed technique suggests that this technique is indicated in the treatment of anterior hypospadias. Long-term analysis of the results strongly encourages regular and prolonged follow-up of children treated for hypospadias in the first 2 years.

CONCLUSION

The modified Duplay technique is reliable, can be easily performed, and gives perfectly satisfactory results, even in the long-term, for the treatment of anterior hypospadias.
