Esiti a lungo termine della mobilizzazione e avanzamento uretrale di Koff nella distalizzazione pediatrica dell'ipospadia e delle reoperazioni: Esperienza di 15 anni in un centro singolo.

INTRODUCTION: Koff urethral mobilization and advancement has shown encouraging results in case of distal hypospadias even though related literature lacks large series and data on long-term follow-up.
