Between 1985 and 1989, 54 boys underwent a MAGPI procedure. Excellent cosmetic and functional results were achieved in 94% of our cases in the early period. In order to assess the long-term results of this procedure, 41 boys attended long-term re-evaluation between 6 and 40 (mean 29) months postoperatively. MAGPI was a very satisfactory procedure for micturition function. We observed in 22% of cases partial and in 15% complete regression. On the long term, excellent cosmetic results were achieved in all glanular cases but in only 65% of coronal and 15% of subcoronal cases. We believe that the MAGPI procedure is not a suitable operation for subcoronal hypospadias.
